您在健身房的哥们说起自己正在使用肌肉和力量训练健身产品时滔滔不绝。您想知道,它们都安全吗?
 
根据美国FDA的规范审查专员药学博士CDR Mark S. Miller的说法,包含类固醇或类固醇类似物的健身产品有可能导致潜在的严重健康风险,如肝脏伤害。“有些肝脏伤害可能致命”,CDR Miller说到。

CDR Miller是评价2009年7月至2016年12月上报至FDA的数百份不良事件报告的负责人。35份报告显示严重的肝损伤。

除了肝损伤外,合成代谢类固醇也有严重的反应,如严重的痤疮、脱发、情绪变化、易怒、攻击性增加和抑郁。它们还与危及生命的反应有关,如肾脏损害、心脏病发作、中风、肺栓塞(肺部的血凝块),以及深静脉血栓形成(在身体深处的血管中出现血块)。

这些健身产品被做为增加肌肉的质量和力量的荷尔蒙产品和/或合成代谢类固醇的替代品来推广。很多这些产品都声称,活性成分能够增强或减少雄性激素、雌激素或类似于孕激素的作用,但实际上却含有合成类固醇或类固醇类似物质、与男性荷尔蒙睾酮相关的合成激素。
 
健身产品可能含有类固醇

美国FDA膳食补充剂项目高级顾问Cara Welch博士解释说,许多在网上和零售商店出售的健身产品都被贴上了“膳食补充剂”的标签。“事实上,”她说,“许多产品根本不是营养补充剂,而是非法销售、未经批准的新药。”在这些公司开始销售之前,FDA尚未对这些产品进行安全性、有效性或质量的审查。

FDA监管事务办公室的监管部门官员Jason Humbert说,在为人体健身推广的产品中可能存在潜在有害的、有时隐藏的成分,这仍是一个令人担忧的问题。他说:“制造这些产品的公司通过利用一个容易获得的市场将这些产品推向消费者,从而触犯了法律。”“最后,消费者通过服用被宣传为有奇效的或口头承诺的产品的危险成分,但并不了解这些风险,从而将自己置身危险的境地。”
 
一些使用健身产品的人热衷于“堆叠”,使用多种产品(包括提供虚假的肝保护的兴奋剂或产品)来提高效果或“增加收益”。这些组合可能会给消费者带来更大的风险,导致严重和威胁生命的反应。

需要做些什么
如果您正在服用任何声称含有类固醇或类固醇类物质的健身产品,FDA建议您立即停止服用,因为使用这些药物有潜在的严重的健康风险,CDR Miller说。FDA还建议您:
•与您的医护人员谈谈您已经或正在计划采取的任何健身产品和/或配方,特别是如果您对这些成分不确定时。
•如果你可能有这些产品相关的症状,特别是恶心、虚弱或疲劳、发烧、腹痛、胸痛、呼吸短促、黄疸(皮肤或眼白发黄)、或褐色或变色的尿液,请咨询您的医护人员。

FDA正在开展监管行动
除了发出警告信外,FDA还可以对这些非法产品的销售者采取其他监管或执法行动。然而,这是很困难的,特别是当卖方只在网上经营的时候。“公司名称或网站经常容易改变,或者产品可以换包装以逃避当局和诈骗消费者,”CDR Humbert说。

FDA鼓励消费者和卫生保健专业人员向FDA的MedWatch安全信息和不良事件报告项目(MedWatch)报告不良事件或与使用这些产品有关的严重副作用。

平衡做母亲和健身的5个贴士

In her farewell post for Today’ ...查看全部

In her farewell post for Today’s Parent, Kristin shares the best tips she’s learned along the way in her journey toward motherhood and optimal fitness.

After the stick turned blue, I swayed in the bathroom for a few minutes by myself, heart racing.

I still held on, in the corner of my mind, to that deeply ingrained expectation that I was destined to be a single mom of one. That I was a bit too old for new beginnings; that my baby days were over.

Logically, I knew that I was no longer single, of course. I knew that my new husband sat outside the closed door, madly typing code into his computer. I understood that we’d made a commitment to be a family, but I think a large part of me expected that our family would include the two of us and my six-year-old son. That was enough. It was so much more than enough. I was rich, provided inexplicably with another shot at unity even after I had failed so miserably the first time. I didn’t really believe that I deserved a second chance.

But the stick was in my hand, and it was blue, and I was going to call Corey in a moment to tell him. But I needed a minute to panic first. I loved our life, the way it was. I loved our party of three, our easy family holidays, our laughter and weekends spent at the gym, running together and skipping and lifting weights. I loved that my son Nolan was my special minion, and that we had a rare and unbreakable connection. I loved that, at the age of 35, I could see my ab muscles clearly for the first time in my life, and that I had more energy and raw, available physical prowess than I’d ever had before. I didn’t know whether I wanted that to change.

I opened the bathroom door, craned my head towards my husband’s desk and said, “I think I might have a faulty pregnancy test. We need to get another one.”

***
Jude Austin was born 10 months later, of course, and I started crying the moment the nurse placed him on my chest. He reached out his miniature hands to grab my face and fiercely stared into my eyes to tell me very clearly that my heart was complete now. At the time, it didn’t matter that my previously fit body was surrounded in a layer of baby padding, that my six-year-old son was no longer my only star. It didn’t matter that I hadn’t expected to be in this position, it only mattered that I was here. By awkwardly navigating our broken and tangled paths, my husband and I managed to find each other to create this insanely perfect new life, and have the family that we were meant to have.

I started a diary after Jude was born, to splice together the pieces of critical monotony and raw, heartstring moments that merge together after a baby is born. I wrote what I was doing and what I wanted to do and, on the side, I wrote here at Today’s Parent about getting back in shape and the quest to regain my fitness.

Truthfully, my fitness represents my mental health, because I’m one of those people who need hard and fast physical release in order to function highly at both professional and emotional levels. I set a goal of bouncing back after four months postpartum, without knowing exactly what that would mean.

I did bounce back physically after that time period as planned and, although I was sideswiped temporarily by abdominal separation, I could see my stomach muscles by four months postpartum. I could deadlift 250 pounds and fling myself around various pull-up bars at the gym. And it felt really good. Getting back into shape quickly required the help of my husband and my family and, though it was feasible and rewarding, that six-pack didn’t seem to matter as much as it used to.

That’s the thing about having a baby: Everyone tells you that your life will change and that you will never be the same but they fail to go into details. The thing is that a baby’s raw, innocent love hurtles into your life on the day you first meet, and nothing else matters — no matter how much you want it to, or how much it mattered before.

I understood that my previous priorities needed to take a backseat for awhile and that was OK, I wanted them to. Down the road, I’d have ample opportunity to work on my weaknesses, to re-emerge into the world where miracles aren’t shooting clearly out of every moment.

***
I have a full-time career, and it’s not an easy one. I have a seven-year-old boy and I need to reassure him that he is still a giant in my life. I have a spirited eight-month-old, and I have my pre-pregnancy body back. By all counts, I have bounced back. It’s time for me to leave this space and figure out what’s next, but I wanted to at least leave you with something practical. I believe fully that exercise must be fun and rewarding in order to be consistent and, as my last post for Today’s Parent, I wanted to pass along every spare piece of wisdom that I have, keeping in mind, of course, that I know no more than the next person.

1) Just do it
There are a million reasons you can’t get down to the gym today: You have meetings, you are exhausted from being up all night with the baby. You’re too old, you want to be able to enjoy your life and eat donuts whenever you want. You are fine if you can’t run a fast mile, there are more important things in life to worry about.

Those things are all true. But there is also truth in the fact that there is nothing better than feeling strong, fit and capable. You will never squeeze out a lunchtime run in the park and regret it afterward. You children will not suffer if you hire a high school babysitter for an hour, and you will not die if you get up an hour early, even if you are exhausted (in fact the early morning exercise will probably make you feel much more alert afterward.) Tell yourself that you are just going to do it. Give yourself permission to stop 10 minutes into it if you really want to. I bet you won’t want to.

2) Turn your diet into a lifestyle
I’ve experimented with diets extensively over the last five years and found that the only one that works is the one where I don’t feel hungry. I like the Paleo diet because it allows for whole unprocessed foods and doesn’t place any emphasis on portion control, measuring food, cheat days, etc. The food is delicious and hearty. Corey and I have landed on a mostly Paleo diet, though we do use cheese here and there and I have recently cut out red meat and pork again. It’s a diet that works to keep us both lean, fuelled and energetic for the kids and I would endorse it fully. If Paleo seems too restrictive, try just cutting out gluten. That made an insane difference to me.

3) Record what you’re doing
There is nothing more gratifying than witnessing your body gain power and efficiency as you get older. We’re told by glossy magazines and on TV that we’re supposed to slow down and fade a bit as we get older.

So when you move, record it. Prove to yourself that it’s totally possible and awesome to get faster and better as you ripen. Run a 5K with everything you’ve got and then, six months later, run the same route and compare your time. It’s amazing how motivating it is to see how we can improve. I record all of my Crossfit workouts, as improvement is an integral part of the sport, but I encourage it for all kinds of fitness: Running, skiing, swimming, whatever. Improving and getting better — and knowing it — is a key part of sticking with it.

4) Know that guilt is useless
If you miss a workout or inhale a cheesecake while watching Here Comes Honey Boo Boo, brush off the graham cracker crumbs and get back to it tomorrow. If you need to go on a business trip to help provide the kind of lifestyle that will allow your family to flourish, don’t feel bad about enjoying that time. An hour of kickboxing will not irreparably harm your new baby. Never allow guilt to prevent you from forging ahead, and remember that now is the only time that matters.

5) Understand that you do not fade to black once you have kids
Often, the Internet will have us believe that we are lesser moms for taking time for ourselves. If we exercise too much, we’re depriving our children. If we don’t breastfeed till XYZ age, our children will suffer. Women spend a lot of time criticizing each other’s choices, and I know I’ve spent a lot of wasted time wondering if some of the judgment was valid.

The thing is, we don’t fade to black once we have children. Many of us are in our late-twenties and thirties — in the prime sweet spot of our lives. We have flourishing careers and deep interests, a passion for our family and for outside interests. We are still beautiful, thriving people and taking the time to follow our own dreams and passions will not detract from our abilities as totally loving mothers. Too much of what I’ve read has suggested that women must give up all of their own pleasures to attend to their kids: My view is that tending to my own happiness makes me a better mom and, in turn, makes my kids happier too.

So I am going to work hard, Crossfit passionately, eat when I want to and enjoy the strength and pride that comes from all of that. I am going to love my boys fiercely and be the best mom I can be by choosing to be the best physical me. I hope you will too.

Thank you so much for following my journey here, and best of luck in your own journeys.

美国梅奥诊所:瑜伽有助于减肥吗?

来自医学博士Donald Hensrud的回答。

一般来说,体育锻炼更有可能防止体重增加,而不是促进减肥。瑜伽似乎也是这样。

大多数瑜伽在消耗能量方面与有氧运动不是一个水平。例如,一个150磅(68公斤)的人进行一小时常规瑜伽可消耗240卡路里,而有氧运动能消耗360卡路里。

但是任何体育锻炼都是有益的。瑜伽至少可让您动起来,并对健康有益,比如改善血脂水平、提振精神。

有规律的体育锻炼应纳入任何的减肥计划中。要减肥,您需要减少能量摄入并增加能量消耗。如您想要练习瑜伽,恰当的方式是将其与骑自行车、慢跑或游泳等有氧运动一并列入运动计划。

来自Katherine Zeratsky, R.D., L.D. 的回答。

您步行的长短和强度以及饮食爱好可能有助于减肥。但是通过改吃低能量的食物似乎比体力活动更有效。

这不是说像步行这种锻炼方式对减肥不重要,而是说如果您在每日饭后可以慢走30分钟的话,一天可以燃烧大约150卡路里的热量。(想一周减掉一磅的话,通常一天就得消耗500卡路里的热量),当然您走的越多、步子越快,燃烧的卡路里也就越多。

为了从运动中获得更多的好处,您的锻炼强度要保持在一个中等或高强度水平。对于减肥而言,您锻炼的强度越大,时间越长,消耗的卡路里就越多。然而,保持平衡很重要,过度运动会增加疼痛、伤害和倦怠的风险。如果您准备进行有规律的锻炼,在刚开始时要进行轻微运动,逐渐地增加到中等或高强度的锻炼。

一旦体重降下来,锻炼就更为重要了,运动有助于预防体重反弹。事实上,研究表明,人们要通过长期有规律的运动才能维持体重。所以,应该坚持步行,但必须遵从健康的饮食习惯。

美国梅奥诊所:全身震动是一个减肥和健身的好方法吗?

来自医学博士Edward R. Laskowski的回答。

全身震动可以提供一些健身和健康的好处,但尚不清楚其是否和定期锻炼一样有益。

全身震动时,你可以站着、坐着或躺在有震动平台的机器上。当机器震动时,它可以将能量传递到您的身体,每一秒您的肌肉可以收缩和放松几十次。这种运动可以让您感觉你自己在运动。

您可以在当地的健身房找到一个全身震动机,或者可以买一个放在家中使用。

支持者建议,一周内运动三次,每次只要15分钟的全身震动即可以减轻体重、燃烧脂肪、提高柔韧的、增强血液流量、减轻运动后的肌肉酸痛,增强肌肉力量,并降低应急皮质醇激素的分泌。

但我们缺乏类似全身震动的综合性的研究。尚不清楚全身震动是否可以像散步、骑自行车或游泳等锻炼一样提供同样的健身益处。

一些研究表明,全身震动可有助于提高肌肉力量,并可以削减卡路里的热量,从而降低体重。

除了运动和健身外,全身震动还有其他的作用。一些研究表明,当正确使用,或必要时在医生监督下使用,全身震动可以:

  • 减少背部疼痛 ,
  • 改善老年人身体的平衡能力 ,
  • 减少骨质流失。

尽管如此,如果您想减肥和改善健康,也要享受健康的饮食,并在日常活动中进行身体锻炼。如果您选择全身震动,记得也要做有氧运动和力量训练。

由于在某些情况下,全身震动是有害的,所以请在使用前与您的医生确认一下,特别是在如果您怀孕或有任何健康问题的情况下。

美国梅奥诊所:尊巴包含什么,它是一种有效的锻炼吗?

来自医学博士Edward R. Laskowski的回答。

尊巴是一种健身项目,包含拉丁音乐和国际音乐舞蹈动作。尊巴常规动作包括快慢节奏交替的间歇训练和阻力训练。

美国卫生与公众服务部(HHS)建议大多数健康成年人每周进行150分钟温和的有氧运动或75分钟剧烈的有氧运动。尊巴作为一种有氧运动,可计入这些时间里。有氧运动可降低健康风险,控制体重超标,强壮心脏,提振精神。如您喜欢尊巴,您就更可能定期进行尊巴锻炼,并体验到其作为有氧运动的益处。

像其他所有运动一样,如果某一动作或姿势伤着您,请调整您的锻炼,以避免剧烈活动。同时,在进行阻力训练时,切记方法正确很重要。别陷在舞蹈里而忘了正确形式。

来自医学博士Edward R. Laskowski的回答。

负重呼啦圈对您的锻炼计划是个很好的补充,特别是当您可以一次可以转呼啦圈10分钟及以上时。事实上,任何形式的呼啦圈运动,包括负重呼啦圈或常规呼啦圈,都可以帮助您实现您的运动目标和提供有氧运动。

负重呼啦圈与传统呼啦圈相比更大且更重。您可以用负重呼啦圈作为您整个健身计划的一部分来增加锻炼的多样性或简单地作为活动身体的一种娱乐方式。

呼啦圈可以和其他类型的有氧运动如跳舞,包括萨尔萨舞、草裙舞、肚皮舞,实现一样的锻炼效果。一个普通女性转30分钟呼啦圈可以消耗165卡路里能量,一个普通男性转30分钟呼啦圈可以消耗200卡路里能量。

请牢记,对于大部分健康成人,美国卫生和人类服务部建议每周至少要做150分钟的中度有氧运动或75分钟的剧烈有氧运动。

如果您想尝试负重呼啦圈运动,选择合适您大小的呼啦圈。呼啦圈静止垂直竖立在地面时应该位于您的腰和胸之间。呼啦圈的重量取决于您自己。越小越轻的呼啦圈,需要消耗更多体力去维持它的转动;反之越大越重的呼啦圈,越容易让它转动,这也意味着您可以让它维持更长的时间。您可以尝试一下不同的呼啦圈再确定您更喜欢的类型和大小。

负重呼啦圈在许多运动商城和网上零售店、甚至一些健身俱乐部都有出售。

如果您有健康问题,特别是背部疾病史,在使用任何形式的呼啦圈前与您的医生确认一下。如果有任何疼痛或其他不适症状,和其他体育锻炼一样,应停止呼啦圈运动并咨询您的医生。

来自医学博士Edward R. Laskowski的回答。

当您散步时,行走杖可以通过功能性的运动让您的手臂、肩膀、胸部和上背的肌肉都活动起来,可以把你日常的散步变成一个全身的锻炼,这种运动也称为北欧式键走(越野行走)。

大多数的行走杖都有个橡胶端头,可以牢牢的抓住人行道;还有一个防静电护腕可以让您胳膊的轴点保持安全。每个手中都可以握个行走杖,每走一步抓下把柄,结实的行走杖可以专为登山设计,称为远足或登山杖。

行走杖有如下好处:

  • 行走杖伴随的手臂可以增加您的有氧运动,帮助燃烧更多的能量。
  • 行走杖可以改善平衡和稳定性
  • 行走杖可以帮助您保持正确的姿势,特别是上背部,可能有助于加强背部肌肉的力量。
  • 行走杖可以帮助降低下背部、臀部和膝盖的负担,如果您的关节或背部有问题,行走杖可能会有所帮助

各种固定或可调节的行走杖均可以在网上商城或运动用品商店内购买到。

美国梅奥诊所:儿童每天需要多大的运动量?

豌豆爸爸 发表了文章 • 0 个评论 • 1130 次浏览 • 2014-10-10 21:39 • 来自相关话题

来自医学博士 Edward R. Laskowski ...查看全部

来自医学博士 Edward R. Laskowski的回答。

Guidelines from the Department of Health and Human Services say that children and adolescents age 6 and older need at least an hour a day of physical activity. Most of the hour should be either moderate or vigorous aerobic activity. In addition, children should participate in muscle-strengthening and bone-strengthening activities at least three days a week.

Many classic activities — such as playing on playground equipment and jumping rope — cover all the bases at once. Organized sports are a great way to stay fit too. But team sports or dance classes aren't the only options.

Get creative as you search for activities your child enjoys. If your child is artistically inclined, take a nature hike to collect leaves and rocks for use in a collage. If your child likes to climb, head for the nearest jungle gym. If your child likes to read, walk or bike to a local library for a book. Or simply turn on your child's favorite music and dance in the living room.

Exercise with your child to better your own health while helping modeling for and stimulating your child to develop good exercise habits.

Remember, incorporating physical activity into your child's daily routine sets the foundation for a lifetime of fitness and good health.

来自Edward R. Laskowski的回答。

对大多数成年人来说,美国卫生和公众服务部(HHS)推荐这些运动指南:
•有氧运动。每周至少150分钟的适中有氧运动或75分钟的剧烈有氧运动。您也可以让适中有氧运动与剧烈有氧运动交错进行。指南建议将这些运动分布在一周的不同时间完成。
•力量训练。一周至少做两次力量训练运动。指南没有特别指明每项强度训练的时间。

适中的有氧运动包括快走、游泳、割草。剧烈有氧运动包括跑步和有氧健身舞蹈。力量训练包括负重器械练习或者攀岩或高强度园艺劳动。

作为一个一般的目标,力争每天至少做30分钟的体力活动。如果您想减肥或达到特定的健身目标,您可能需要更多的运动。想要力争更高的目标?如果您加大运动到每周300分钟,您可以获得更多健康益处,包括减肥。

担心没有整块的时间来锻炼?即使简短的一次次活动也是有好处的。比如,如果您不能适应一次行走30分钟,可以试下分3次行走10分钟。最重要的是让规律的体育锻炼成为你生活的一部分。

美国FDA:警告!健身产品有风险

豌豆爸爸 发表了文章 • 0 个评论 • 402 次浏览 • 2017-06-26 11:20 • 来自相关话题

您在健身房的哥们说起自己正在使用肌肉和力量 ...查看全部


您在健身房的哥们说起自己正在使用肌肉和力量训练健身产品时滔滔不绝。您想知道,它们都安全吗?
 
根据美国FDA的规范审查专员药学博士CDR Mark S. Miller的说法,包含类固醇或类固醇类似物的健身产品有可能导致潜在的严重健康风险,如肝脏伤害。“有些肝脏伤害可能致命”,CDR Miller说到。

CDR Miller是评价2009年7月至2016年12月上报至FDA的数百份不良事件报告的负责人。35份报告显示严重的肝损伤。

除了肝损伤外,合成代谢类固醇也有严重的反应,如严重的痤疮、脱发、情绪变化、易怒、攻击性增加和抑郁。它们还与危及生命的反应有关,如肾脏损害、心脏病发作、中风、肺栓塞(肺部的血凝块),以及深静脉血栓形成(在身体深处的血管中出现血块)。

这些健身产品被做为增加肌肉的质量和力量的荷尔蒙产品和/或合成代谢类固醇的替代品来推广。很多这些产品都声称,活性成分能够增强或减少雄性激素、雌激素或类似于孕激素的作用,但实际上却含有合成类固醇或类固醇类似物质、与男性荷尔蒙睾酮相关的合成激素。
 
健身产品可能含有类固醇

美国FDA膳食补充剂项目高级顾问Cara Welch博士解释说,许多在网上和零售商店出售的健身产品都被贴上了“膳食补充剂”的标签。“事实上,”她说,“许多产品根本不是营养补充剂,而是非法销售、未经批准的新药。”在这些公司开始销售之前,FDA尚未对这些产品进行安全性、有效性或质量的审查。

FDA监管事务办公室的监管部门官员Jason Humbert说,在为人体健身推广的产品中可能存在潜在有害的、有时隐藏的成分,这仍是一个令人担忧的问题。他说:“制造这些产品的公司通过利用一个容易获得的市场将这些产品推向消费者,从而触犯了法律。”“最后,消费者通过服用被宣传为有奇效的或口头承诺的产品的危险成分,但并不了解这些风险,从而将自己置身危险的境地。”
 
一些使用健身产品的人热衷于“堆叠”,使用多种产品(包括提供虚假的肝保护的兴奋剂或产品)来提高效果或“增加收益”。这些组合可能会给消费者带来更大的风险,导致严重和威胁生命的反应。

需要做些什么
如果您正在服用任何声称含有类固醇或类固醇类物质的健身产品,FDA建议您立即停止服用,因为使用这些药物有潜在的严重的健康风险,CDR Miller说。FDA还建议您:
•与您的医护人员谈谈您已经或正在计划采取的任何健身产品和/或配方,特别是如果您对这些成分不确定时。
•如果你可能有这些产品相关的症状,特别是恶心、虚弱或疲劳、发烧、腹痛、胸痛、呼吸短促、黄疸(皮肤或眼白发黄)、或褐色或变色的尿液,请咨询您的医护人员。

FDA正在开展监管行动
除了发出警告信外,FDA还可以对这些非法产品的销售者采取其他监管或执法行动。然而,这是很困难的,特别是当卖方只在网上经营的时候。“公司名称或网站经常容易改变,或者产品可以换包装以逃避当局和诈骗消费者,”CDR Humbert说。

FDA鼓励消费者和卫生保健专业人员向FDA的MedWatch安全信息和不良事件报告项目(MedWatch)报告不良事件或与使用这些产品有关的严重副作用。

平衡做母亲和健身的5个贴士

In her farewell post for Today’s Parent, Kristin shares the best tips she’s learned along the way in her journey toward motherhood and optimal fitness.

After the stick turned blue, I swayed in the bathroom for a few minutes by myself, heart racing.

I still held on, in the corner of my mind, to that deeply ingrained expectation that I was destined to be a single mom of one. That I was a bit too old for new beginnings; that my baby days were over.

Logically, I knew that I was no longer single, of course. I knew that my new husband sat outside the closed door, madly typing code into his computer. I understood that we’d made a commitment to be a family, but I think a large part of me expected that our family would include the two of us and my six-year-old son. That was enough. It was so much more than enough. I was rich, provided inexplicably with another shot at unity even after I had failed so miserably the first time. I didn’t really believe that I deserved a second chance.

But the stick was in my hand, and it was blue, and I was going to call Corey in a moment to tell him. But I needed a minute to panic first. I loved our life, the way it was. I loved our party of three, our easy family holidays, our laughter and weekends spent at the gym, running together and skipping and lifting weights. I loved that my son Nolan was my special minion, and that we had a rare and unbreakable connection. I loved that, at the age of 35, I could see my ab muscles clearly for the first time in my life, and that I had more energy and raw, available physical prowess than I’d ever had before. I didn’t know whether I wanted that to change.

I opened the bathroom door, craned my head towards my husband’s desk and said, “I think I might have a faulty pregnancy test. We need to get another one.”

***
Jude Austin was born 10 months later, of course, and I started crying the moment the nurse placed him on my chest. He reached out his miniature hands to grab my face and fiercely stared into my eyes to tell me very clearly that my heart was complete now. At the time, it didn’t matter that my previously fit body was surrounded in a layer of baby padding, that my six-year-old son was no longer my only star. It didn’t matter that I hadn’t expected to be in this position, it only mattered that I was here. By awkwardly navigating our broken and tangled paths, my husband and I managed to find each other to create this insanely perfect new life, and have the family that we were meant to have.

I started a diary after Jude was born, to splice together the pieces of critical monotony and raw, heartstring moments that merge together after a baby is born. I wrote what I was doing and what I wanted to do and, on the side, I wrote here at Today’s Parent about getting back in shape and the quest to regain my fitness.

Truthfully, my fitness represents my mental health, because I’m one of those people who need hard and fast physical release in order to function highly at both professional and emotional levels. I set a goal of bouncing back after four months postpartum, without knowing exactly what that would mean.

I did bounce back physically after that time period as planned and, although I was sideswiped temporarily by abdominal separation, I could see my stomach muscles by four months postpartum. I could deadlift 250 pounds and fling myself around various pull-up bars at the gym. And it felt really good. Getting back into shape quickly required the help of my husband and my family and, though it was feasible and rewarding, that six-pack didn’t seem to matter as much as it used to.

That’s the thing about having a baby: Everyone tells you that your life will change and that you will never be the same but they fail to go into details. The thing is that a baby’s raw, innocent love hurtles into your life on the day you first meet, and nothing else matters — no matter how much you want it to, or how much it mattered before.

I understood that my previous priorities needed to take a backseat for awhile and that was OK, I wanted them to. Down the road, I’d have ample opportunity to work on my weaknesses, to re-emerge into the world where miracles aren’t shooting clearly out of every moment.

***
I have a full-time career, and it’s not an easy one. I have a seven-year-old boy and I need to reassure him that he is still a giant in my life. I have a spirited eight-month-old, and I have my pre-pregnancy body back. By all counts, I have bounced back. It’s time for me to leave this space and figure out what’s next, but I wanted to at least leave you with something practical. I believe fully that exercise must be fun and rewarding in order to be consistent and, as my last post for Today’s Parent, I wanted to pass along every spare piece of wisdom that I have, keeping in mind, of course, that I know no more than the next person.

1) Just do it
There are a million reasons you can’t get down to the gym today: You have meetings, you are exhausted from being up all night with the baby. You’re too old, you want to be able to enjoy your life and eat donuts whenever you want. You are fine if you can’t run a fast mile, there are more important things in life to worry about.

Those things are all true. But there is also truth in the fact that there is nothing better than feeling strong, fit and capable. You will never squeeze out a lunchtime run in the park and regret it afterward. You children will not suffer if you hire a high school babysitter for an hour, and you will not die if you get up an hour early, even if you are exhausted (in fact the early morning exercise will probably make you feel much more alert afterward.) Tell yourself that you are just going to do it. Give yourself permission to stop 10 minutes into it if you really want to. I bet you won’t want to.

2) Turn your diet into a lifestyle
I’ve experimented with diets extensively over the last five years and found that the only one that works is the one where I don’t feel hungry. I like the Paleo diet because it allows for whole unprocessed foods and doesn’t place any emphasis on portion control, measuring food, cheat days, etc. The food is delicious and hearty. Corey and I have landed on a mostly Paleo diet, though we do use cheese here and there and I have recently cut out red meat and pork again. It’s a diet that works to keep us both lean, fuelled and energetic for the kids and I would endorse it fully. If Paleo seems too restrictive, try just cutting out gluten. That made an insane difference to me.

3) Record what you’re doing
There is nothing more gratifying than witnessing your body gain power and efficiency as you get older. We’re told by glossy magazines and on TV that we’re supposed to slow down and fade a bit as we get older.

So when you move, record it. Prove to yourself that it’s totally possible and awesome to get faster and better as you ripen. Run a 5K with everything you’ve got and then, six months later, run the same route and compare your time. It’s amazing how motivating it is to see how we can improve. I record all of my Crossfit workouts, as improvement is an integral part of the sport, but I encourage it for all kinds of fitness: Running, skiing, swimming, whatever. Improving and getting better — and knowing it — is a key part of sticking with it.

4) Know that guilt is useless
If you miss a workout or inhale a cheesecake while watching Here Comes Honey Boo Boo, brush off the graham cracker crumbs and get back to it tomorrow. If you need to go on a business trip to help provide the kind of lifestyle that will allow your family to flourish, don’t feel bad about enjoying that time. An hour of kickboxing will not irreparably harm your new baby. Never allow guilt to prevent you from forging ahead, and remember that now is the only time that matters.

5) Understand that you do not fade to black once you have kids
Often, the Internet will have us believe that we are lesser moms for taking time for ourselves. If we exercise too much, we’re depriving our children. If we don’t breastfeed till XYZ age, our children will suffer. Women spend a lot of time criticizing each other’s choices, and I know I’ve spent a lot of wasted time wondering if some of the judgment was valid.

The thing is, we don’t fade to black once we have children. Many of us are in our late-twenties and thirties — in the prime sweet spot of our lives. We have flourishing careers and deep interests, a passion for our family and for outside interests. We are still beautiful, thriving people and taking the time to follow our own dreams and passions will not detract from our abilities as totally loving mothers. Too much of what I’ve read has suggested that women must give up all of their own pleasures to attend to their kids: My view is that tending to my own happiness makes me a better mom and, in turn, makes my kids happier too.

So I am going to work hard, Crossfit passionately, eat when I want to and enjoy the strength and pride that comes from all of that. I am going to love my boys fiercely and be the best mom I can be by choosing to be the best physical me. I hope you will too.

Thank you so much for following my journey here, and best of luck in your own journeys.

美国梅奥诊所:瑜伽有助于减肥吗?

来自医学博士Donald Hensrud的回答。

一般来说,体育锻炼更有可能防止体重增加,而不是促进减肥。瑜伽似乎也是这样。

大多数瑜伽在消耗能量方面与有氧运动不是一个水平。例如,一个150磅(68公斤)的人进行一小时常规瑜伽可消耗240卡路里,而有氧运动能消耗360卡路里。

但是任何体育锻炼都是有益的。瑜伽至少可让您动起来,并对健康有益,比如改善血脂水平、提振精神。

有规律的体育锻炼应纳入任何的减肥计划中。要减肥,您需要减少能量摄入并增加能量消耗。如您想要练习瑜伽,恰当的方式是将其与骑自行车、慢跑或游泳等有氧运动一并列入运动计划。

来自Katherine Zeratsky, R.D., L.D. 的回答。

您步行的长短和强度以及饮食爱好可能有助于减肥。但是通过改吃低能量的食物似乎比体力活动更有效。

这不是说像步行这种锻炼方式对减肥不重要,而是说如果您在每日饭后可以慢走30分钟的话,一天可以燃烧大约150卡路里的热量。(想一周减掉一磅的话,通常一天就得消耗500卡路里的热量),当然您走的越多、步子越快,燃烧的卡路里也就越多。

为了从运动中获得更多的好处,您的锻炼强度要保持在一个中等或高强度水平。对于减肥而言,您锻炼的强度越大,时间越长,消耗的卡路里就越多。然而,保持平衡很重要,过度运动会增加疼痛、伤害和倦怠的风险。如果您准备进行有规律的锻炼,在刚开始时要进行轻微运动,逐渐地增加到中等或高强度的锻炼。

一旦体重降下来,锻炼就更为重要了,运动有助于预防体重反弹。事实上,研究表明,人们要通过长期有规律的运动才能维持体重。所以,应该坚持步行,但必须遵从健康的饮食习惯。

美国梅奥诊所:全身震动是一个减肥和健身的好方法吗?

来自医学博士Edward R. Laskowski的回答。

全身震动可以提供一些健身和健康的好处,但尚不清楚其是否和定期锻炼一样有益。

全身震动时,你可以站着、坐着或躺在有震动平台的机器上。当机器震动时,它可以将能量传递到您的身体,每一秒您的肌肉可以收缩和放松几十次。这种运动可以让您感觉你自己在运动。

您可以在当地的健身房找到一个全身震动机,或者可以买一个放在家中使用。

支持者建议,一周内运动三次,每次只要15分钟的全身震动即可以减轻体重、燃烧脂肪、提高柔韧的、增强血液流量、减轻运动后的肌肉酸痛,增强肌肉力量,并降低应急皮质醇激素的分泌。

但我们缺乏类似全身震动的综合性的研究。尚不清楚全身震动是否可以像散步、骑自行车或游泳等锻炼一样提供同样的健身益处。

一些研究表明,全身震动可有助于提高肌肉力量,并可以削减卡路里的热量,从而降低体重。

除了运动和健身外,全身震动还有其他的作用。一些研究表明,当正确使用,或必要时在医生监督下使用,全身震动可以:

  • 减少背部疼痛 ,
  • 改善老年人身体的平衡能力 ,
  • 减少骨质流失。

尽管如此,如果您想减肥和改善健康,也要享受健康的饮食,并在日常活动中进行身体锻炼。如果您选择全身震动,记得也要做有氧运动和力量训练。

由于在某些情况下,全身震动是有害的,所以请在使用前与您的医生确认一下,特别是在如果您怀孕或有任何健康问题的情况下。

美国梅奥诊所:尊巴包含什么,它是一种有效的锻炼吗?

来自医学博士Edward R. Laskowski的回答。

尊巴是一种健身项目,包含拉丁音乐和国际音乐舞蹈动作。尊巴常规动作包括快慢节奏交替的间歇训练和阻力训练。

美国卫生与公众服务部(HHS)建议大多数健康成年人每周进行150分钟温和的有氧运动或75分钟剧烈的有氧运动。尊巴作为一种有氧运动,可计入这些时间里。有氧运动可降低健康风险,控制体重超标,强壮心脏,提振精神。如您喜欢尊巴,您就更可能定期进行尊巴锻炼,并体验到其作为有氧运动的益处。

像其他所有运动一样,如果某一动作或姿势伤着您,请调整您的锻炼,以避免剧烈活动。同时,在进行阻力训练时,切记方法正确很重要。别陷在舞蹈里而忘了正确形式。

来自医学博士Edward R. Laskowski的回答。

负重呼啦圈对您的锻炼计划是个很好的补充,特别是当您可以一次可以转呼啦圈10分钟及以上时。事实上,任何形式的呼啦圈运动,包括负重呼啦圈或常规呼啦圈,都可以帮助您实现您的运动目标和提供有氧运动。

负重呼啦圈与传统呼啦圈相比更大且更重。您可以用负重呼啦圈作为您整个健身计划的一部分来增加锻炼的多样性或简单地作为活动身体的一种娱乐方式。

呼啦圈可以和其他类型的有氧运动如跳舞,包括萨尔萨舞、草裙舞、肚皮舞,实现一样的锻炼效果。一个普通女性转30分钟呼啦圈可以消耗165卡路里能量,一个普通男性转30分钟呼啦圈可以消耗200卡路里能量。

请牢记,对于大部分健康成人,美国卫生和人类服务部建议每周至少要做150分钟的中度有氧运动或75分钟的剧烈有氧运动。

如果您想尝试负重呼啦圈运动,选择合适您大小的呼啦圈。呼啦圈静止垂直竖立在地面时应该位于您的腰和胸之间。呼啦圈的重量取决于您自己。越小越轻的呼啦圈,需要消耗更多体力去维持它的转动;反之越大越重的呼啦圈,越容易让它转动,这也意味着您可以让它维持更长的时间。您可以尝试一下不同的呼啦圈再确定您更喜欢的类型和大小。

负重呼啦圈在许多运动商城和网上零售店、甚至一些健身俱乐部都有出售。

如果您有健康问题,特别是背部疾病史,在使用任何形式的呼啦圈前与您的医生确认一下。如果有任何疼痛或其他不适症状,和其他体育锻炼一样,应停止呼啦圈运动并咨询您的医生。

来自医学博士Edward R. Laskowski的回答。

当您散步时,行走杖可以通过功能性的运动让您的手臂、肩膀、胸部和上背的肌肉都活动起来,可以把你日常的散步变成一个全身的锻炼,这种运动也称为北欧式键走(越野行走)。

大多数的行走杖都有个橡胶端头,可以牢牢的抓住人行道;还有一个防静电护腕可以让您胳膊的轴点保持安全。每个手中都可以握个行走杖,每走一步抓下把柄,结实的行走杖可以专为登山设计,称为远足或登山杖。

行走杖有如下好处:

  • 行走杖伴随的手臂可以增加您的有氧运动,帮助燃烧更多的能量。
  • 行走杖可以改善平衡和稳定性
  • 行走杖可以帮助您保持正确的姿势,特别是上背部,可能有助于加强背部肌肉的力量。
  • 行走杖可以帮助降低下背部、臀部和膝盖的负担,如果您的关节或背部有问题,行走杖可能会有所帮助

各种固定或可调节的行走杖均可以在网上商城或运动用品商店内购买到。

美国梅奥诊所:儿童每天需要多大的运动量?

来自医学博士 Edward R. Laskowski ...查看全部

来自医学博士 Edward R. Laskowski的回答。

Guidelines from the Department of Health and Human Services say that children and adolescents age 6 and older need at least an hour a day of physical activity. Most of the hour should be either moderate or vigorous aerobic activity. In addition, children should participate in muscle-strengthening and bone-strengthening activities at least three days a week.

Many classic activities — such as playing on playground equipment and jumping rope — cover all the bases at once. Organized sports are a great way to stay fit too. But team sports or dance classes aren't the only options.

Get creative as you search for activities your child enjoys. If your child is artistically inclined, take a nature hike to collect leaves and rocks for use in a collage. If your child likes to climb, head for the nearest jungle gym. If your child likes to read, walk or bike to a local library for a book. Or simply turn on your child's favorite music and dance in the living room.

Exercise with your child to better your own health while helping modeling for and stimulating your child to develop good exercise habits.

Remember, incorporating physical activity into your child's daily routine sets the foundation for a lifetime of fitness and good health.

来自Edward R. Laskowski的回答。

对大多数成年人来说,美国卫生和公众服务部(HHS)推荐这些运动指南:
•有氧运动。每周至少150分钟的适中有氧运动或75分钟的剧烈有氧运动。您也可以让适中有氧运动与剧烈有氧运动交错进行。指南建议将这些运动分布在一周的不同时间完成。
•力量训练。一周至少做两次力量训练运动。指南没有特别指明每项强度训练的时间。

适中的有氧运动包括快走、游泳、割草。剧烈有氧运动包括跑步和有氧健身舞蹈。力量训练包括负重器械练习或者攀岩或高强度园艺劳动。

作为一个一般的目标,力争每天至少做30分钟的体力活动。如果您想减肥或达到特定的健身目标,您可能需要更多的运动。想要力争更高的目标?如果您加大运动到每周300分钟,您可以获得更多健康益处,包括减肥。

担心没有整块的时间来锻炼?即使简短的一次次活动也是有好处的。比如,如果您不能适应一次行走30分钟,可以试下分3次行走10分钟。最重要的是让规律的体育锻炼成为你生活的一部分。

健身的范围很广阔,体育只是健身中的一个版块。健身除了体育含括的项目之外,还有很多内容,例如,写字、唱歌、做家务等。健身大致分为器械锻炼和非器械锻炼。 健身也是很多男士和女士用来塑造完美身材的一种锻炼方式,很流行的健身房中的男男女女都喜欢这项运动。
