DrSugar Answers: Postworkout Weakness?

DrSugar — Wed, 03 Dec 2008 05:30:00 PST

DrSugar is in the house and answering your questions.

Dear DrSugar,
Sometimes after a rigorous cardio workout (one hour, doing intervals for the first half hour and steady pace for the second half), I come home and start feeling queasy and weak, then need to lie down. Sometimes I feel this way for an hour or more postworkout, well after I've showered and eaten. There have been a few times when I've lost my stomach as well. But it usually goes away after an hour or so of resting/lying down. What's going on? I try to be well hydrated and have a little snack a bit before working out, but sometimes, it doesn't seem to help.

If you're curious to see how DrSugar answers this question, just

Feeling queasy or weak following or during rigorous exercise could be due to a variety of factors; however, lactic acidosis is the most likely cause of your symptoms. Lactic acid is produced by muscles during anaerobic metabolism. Lactic acidosis most commonly occurs after long, rigorous exercise like you’ve described. Common symptoms of lactic acidosis include nausea, weakness, fast heart rate, hyperventilation, and sometimes even anxiety. Lactic acidosis can be more of a problem when coupled with dehydration, prolonged exercise, starvation, alcohol use, and strenuous exercise when not in excellent physical condition.

Preventing lactic acidosis can be difficult if your goal is prolonged anaerobic exercise such as sprints or intervals. The first step is to maintain adequate hydration before, during, and after your workouts. Another way to avoid this problem is to separate your aerobic and anaerobic workouts on alternate days by jogging Mondays, Wednesdays, and Fridays and doing sprints, intervals, and/or weights Tuesdays and Thursdays.

The other possible cause of your symptoms is low blood sugar, which can also cause weakness or queasiness during or after exercise. To prevent low blood sugar you can avoid prolonged exercise on an empty stomach, before breakfast, or before dinner if you didn’t eat an adequate lunch. And, of course, always avoid starvation diets. They don’t work and they are dangerous. Sometimes these post-exercise symptoms can be related to an underlying metabolic problem such as diabetes or liver disease, therefore it is highly recommended that you see a physician if the problem persists.

3 Ways Walkers Can Benefit From Going Barefoot

Jenny Sugar — Thu, 10 May 2012 13:57:41 PDT

If you're into running, there's no doubt you've heard the buzz about barefoot running. It's become trendy for a reason: running barefoot can help you have better form and technique, preventing injury and pain. Runners aren't the only ones who can benefit from ditching their footwear. If walking is your exercise of choice, here are some reasons you'll want to try going barefoot.

Active and engaged muscles: Slipping on shoes may protect your feet from dangers, but it also means the muscles in your feet don't have to work as hard. The cushioned sole of a shoe absorbs all the sensations and pressures, which means your feet have become more passive over time. Because weak muscles are more prone to strain, pain, and injury, walking barefoot allows you to engage your body more, making feet stronger and better able to handle workouts.
Better walking form: One way a walker can have incorrect form is by roughly pounding the ground with each step. Cushiony sneakers absorb the force, so you're not even aware that you may be walking incorrectly. Remove your shoes and you'll instantly walk lighter, causing less jarring impact on your joints. Even though walking is considered a low-impact sport, it's still hard on your feet. Improving form means less risk for injury.
Busting through the walking plateau: Walking the same way, day in and day out, means using identical muscles every time you head out for a walk. Your body quickly strengthens the muscles in use, easily adapting to the demands placed on them. Without the opportunity for new challenges, muscles won't become stronger and can actually become injured from overuse. Walking barefoot forces your body to use other muscles not normally used when walking with sneaks, which helps you achieve a more effective and different type of workout. You'll especially feel the difference when walking barefoot on different surfaces.

5 Tricks to Get the Most Out of Your Outdoor Run

Shape — Thu, 03 May 2012 04:11:45 PDT

We are pumped to share one of our fave stories from Shape here on FitSugar. This week Shape turns to celebrity trainer Jay Cardiello for some help!

The weather is getting nice and you may have been bitten by the "run bug." To make the transition from indoor runs to the great outdoors seamless and safe, I compiled a list of my top five tricks to get the most out of your outdoor run. Whether you have had some success running on the treadmill, or you are completely new to outdoor running, there are two crucial factors that you must understand.

25 Most Deceiving Exercises (They Tone More Than You Think).

First, let's talk about a little guy named Newton. See, Newton has this law that states that for every action, there is an equal and opposite reaction. Are you with me so far? Good. Well, with runners, the concern is what we run on. The harder the surface the greater the ground reaction force, which is basically the force exerted by the ground back onto the body (in this case, our little legs) that are in contact with it, is. To simplify this, surfaces like concrete and pavement will cause a greater reaction back into our joints and legs than an energy absorbing treadmill. This not only makes us work harder, but will tire us out faster and cause greater stress on our joints.

Are Your Workouts Causing Pain? How to Find Out.

Second, the treadmill is a flat belt that provides consistency with each step. There are no stones, traffic, or inclement weather activity that would cause you to be off balance or have to change your gait. Running outdoors forces the body to make constant small adjustments. That said, here is what’s going to make your outdoor run a successful one.

5 Fitness Myths That Mess With Results

Prevention — Mon, 30 Apr 2012 04:31:20 PDT

We are pumped to share one of our fave stories from Prevention here on FitSugar!

By Jenna Bergen, Prevention

With so many people offering advice on weight loss, it can be hard to separate fact from fiction. All too often I’ve overheard a hardworking gym-goer sharing a well-meaning but ill-informed tip with another exerciser. And I’m not the only one who’s heard fitness folklore being swapped on the training room floor. I spoke to top experts in the field to find out the common fitness myths they hear from clients. From the pseudo miracles of the "fat-burning" zone to the misguided magic of working out on an empty stomach, these fitness falsehoods should never be followed.

Nine Exercise Moves You're Doing Wrong

Myth No. One: Keep your heart rate in the fat-burning zone

If you've been exercising at 60 to 70 percent of your maximum heart rate in order to shed flab faster, you could be slowing your slim down. "The fat-burning zone is a complete myth," says Wayne Westcott, PhD, Prevention advisory board member and fitness research director at Quincy College. "While it's true that you burn a higher percentage of fat calories when exercising at a moderate pace, you burn fewer calories overall." For instance, if you get on a treadmill and walk at a 3.5 mph pace for 30 minutes, you might burn 250 calories. If you raise the speed to seven miles per hour, you’d burn 500. Bottom line? "It’s much better to go at the faster speed." Prefer the elliptical trainer? Make sure you're not making one of the top 10 elliptical trainer mistakes.

Myth No. Two: Boosting cardio is the best way to bypass a plateau

"The most effective way to lose weight is to include both cardio and weights in your routine," says Jari Love, star of the Get Extremely Ripped: 1000 Hardcore DVD. "One study found that when individuals cycled for 30 minutes a day, they lost three pounds of fat and gained a half pound of muscle in eight weeks. But individuals who cycled for 15 minutes and weight trained for 15 minutes a day lost 10 pounds of fat and gained two pounds of calorie-burning muscle."

The 4 Things Runners Need to Do Every Week

Jenny Sugar — Wed, 14 Mar 2012 17:08:03 PDT

Running is one of the most popular forms of cardio because it's inexpensive, you can do it anywhere, and it burns major calories while toning your lower body. That said, if you run, here are four things you should be doing every week.

Vary your workouts: Doing the same running workout all the time can not only be boring, but can also lead to overuse injuries in the muscles. Mix up the surface you run on, change up your pace (don't forget sprinting intervals), incorporate hills, and vary the distance you run. You'll be amazed at how strong your body becomes and how mixing it up makes you a better runner. Also be sure to incorporate other forms of exercise such as cycling, swimming, strength training, and yoga to give your body a break from the same movement.
Stretch it out: Don't skip out on stretching after your run (and never static stretch before). It not only feels good, but stretching will also relieve soreness and increase your flexibility - supple muscles are also less prone to pain and injury. Focus on stretches that target the hips, hamstrings, lower back, and shoulders. Follow along with this video to learn a yoga series for runners. You can also use a foam roller to stretch and massage your muscles. Rolling out your IT band can prevent knee, back, or hip issues, and here are five other foam roller exercises for runners.

Get a Grip on Indulgences With Trainer Gunnar Peterson's Tips

Leta Shy — Thu, 26 Jan 2012 14:55:48 PST

Indulgences can get the best of us at any turn. Whether it's a co-worker's plate of cookies or a strong desire to skip a workout in favor of happy hour, it can be hard to stick with a routine when you notice temptations left and right. We recently spoke with celebrity trainer Gunnar Peterson, the man behind some of the curviest bodies in Hollywood, who offered these tips on how to get a grip when we're craving unhealthy food or have skipped a workout.

Have a healthy outlook: Most people have an indulgence or two that leaves them weak in the knees (even Gunnar's got one: "Peanut butter is death for me. I would shank my grandmother in the neck for a Reese's Peanut Butter Cup," he jokes). Instead of banning your favorite junk food from your diet completely, make healthy choices most of the time, but allow yourself some leeway in all aspects of your healthy lifestyle. "Just try and make the right choices most of the time," Gunnar says. "If you make them all the time then you're just flat out boring and then you become a weird fitness zealot, and at the end of the day nobody wants to be around you."

Get out of the kitchen: If the kitchen table is your go-to spot for paying bills or finishing up work in the evening, you may find that just being around all that food can lead to mindless snacking. As Gunnar jokes, "If all bachelor parties were held in movie theaters there would be a lot less bad stuff that happens at bachelor parties." Take temptation out of the equation by getting out of the kitchen after you're done eating for the night.

Mistakes You're Making on the Pilates Mat

Susi May — Tue, 24 Jan 2012 02:51:53 PST

Mat classes are the most affordable way to reap the benefits of Pilates. Taught across the country at gyms and private studios, group classes mean you don't have an instructor cuing and correcting your every move. Make the most of your time on the mat and be mindful of these common mistakes I've seen in classes over the years.

Not Going Deep
There are many benefits to Pilates, but getting in touch with the deep abs, aka the transverse abdominals, is, to me, the most important. If the deep abs are working, then all four layers of ab muscles will be working right along with it, making for a very stable torso. In class, use every exhale as opportunity to reengage your abs and pull them into your spine with a little lift up. If the abs are pooching outward, you're only working the top layer of the abs and training them to pull away from the spine - the opposite effect of what you want.

Momentum Is Not Your Friend
Deliberate pauses are built into the choreography of many Pilates exercises to prevent momentum from taking over the motion. The Pilates method was originally named Contrology (the study of control) to emphasize this very concept. Going slowly is key. Jayme Boyle, the group fitness coordinator and Pillates mat instructor at the SF Equinox, explains the importance of forgoing momentum like this: "Slower pace means you’re turning on stabilizing muscles and you’re creating more isometric contractions." And I have to agree. Pilates is not a race.

From the Community: the Best Exercise You Aren't Doing

Fit Community — Mon, 23 Jan 2012 01:10:46 PST

FitSugar community member (and fitness instructor) livinginthin has shared a how-to on an overlooked exercise that everyone should be doing.

Running, cycling, squatting, jumping, curling, crunches, and lunging - you do it all, right? Well, the one move you aren’t doing is probably the one that can keep you doing all those things (and more), pain and injury-free for a lifetime.

What is it? Dorsiflexion. In layperson’s terms, dorsiflexion is the action of the foot that occurs when you pull your toes back toward your shin, engaging the foot and ankle muscles (the tibialis anterior, extensor hallucis longus, and extensor digitorum longus).

Weak muscles in this part of the leg can cause everything from muscular imbalances to an impaired gait and even tripping and falling (as we age, we lose even more strength in this area, which makes it harder to step properly), says Dr. Yoav Suprun, PT, Dip. MDT, a certified personal trainer, physical therapist, and owner of SOBE Spine in Miami Beach, FL.

What Do You Love Most About Your Gym?

Leta Shy — Thu, 19 Jan 2012 12:29:13 PST

I love going to the gym. Planning a gym schedule each week not only makes me more apt to stick to my workout routine, but it also encourages me to focus on muscle-building exercises - which is my weakness, since I love to run outside but never want to strength-train at home.

Before I signed up for my latest gym, however, I found every excuse to skip the trek to my former club. It was more than a mile away and not convenient to any public transit, so the walk-workout-walk necessity made for a big time commitment.

Now that my new gym is mere blocks from my office, it's easy to squeeze in a short lunchtime workout or stop by after work. While I like the better layout and amenities (especially the classes!) of my new gym over my former one, its convenient location is the most important aspect of staying committed to my workouts. What's yours?
