You might be interested in reading this about the research of the late prof. Buteyko: @MR04: "controlling your breathing and taking in large breaths increases blood flow and provides oxygen faster to your brain and the rest of your body." Not necessarily. If you lose too much CO2 by breathing too much, you'll actually reduce available oxygen for the ...

It depends why you're running. If you're running to build your general aerobic and cardiovascular fitness, the rule of thumb I learned in the US Marine Corps is not to follow a particular breathing pattern, but to aim for a certain level of exertion. You should be breathing in a way that allows you to talk, but not sing. If you can sing at a normal tempo, ...

Breathing in for 4 lefts and out for 4, like you are doing seems extreme, especially for a beginner runner. In for 2 left, out for 2 is probably what they mean in that article. It also matches most Army running cadences, by the way.

If humans run, their breathing is not connected to their stride. Why don't you just breath the way it is comfortable with you? Especially when you just started to run, you shouldn't worry about anything like breathing patterns. Just try to find the "fun" in running!

When you say breathe in, L, R, L, R; breathe out, L, R, L, R we like to call this 4:4. That is 4 steps on inhale, 4 steps on exhale. This study tries to analyze some of the breathing dynamics of humans during running. While it's pretty long and technical, it's been written about in more layman's terms here. The gist of it suggests that a 2:1 pattern ...

The analysis suffers from causality. A measured amount of exercise to produce a heart rate does not necessarily mean the reverse. I see that false statistic used for hot Yoga burns more calories as the heart beats faster. In heat the blood vessels in the surface of the skin dilate and blood flow increases to help cool the body. This is not blood ...

Short while ago i did dinghy sailing for a couple of hours. The wind was strong but i was sailing with little effort under reduced sail. My heart rate was very high not because of physical exertion but out of alertness. My watch predicted that i burnt 1.800 calories in two and a half hours which is waay off. The formula does not include factors driven by ...

Worth noting, without data from an ECG (heart rate monitor) and face mask based gas analyzers, along with details of the gradient, wind speed, and surface there aren't any accurate equations. The best you can do is to estimate a VO2 (mL·kg-1·min-1) figure, and convert that into a Kcal one: Kcal/Min ~= respiratoryExchangeRatio * massKg * VO2 / 1000 ...

Just to provide some background, lightning is a real problem and causes a lot of casualties. From Medicine for Mountaineering, 6th Edition: Lightning was the second most common cause of weather-related death over the forty-year period from 1962 to 2002. Only floods, many of which are also produced by thunderstorms, killed more people during this ...

The Nike Hyperfeel Shoes are intended to offer a light, barefoot feel. However, if they are causing blisters for the user then it would be advised to use a low no-show sock with them to prevent the blisters. If you’re looking for a completely unique barefoot feel experience check out the Nike Free 1.0 Cross Bionic Here is a newer shoe that may fill ...

Based on the information in the answer to a question on the benefits on the benefits of running in the heat, you may indeed be reaping some benefits. At least one study shows: Heat acclimation improves the body’s ability to control body temperature, improves sweating and increases blood flow through the skin, and expands blood volume allowing the heart ...

The current theory states that there's two types of muscle mass, sarcoplasmic, and myofibrallar. Sarcoplasmic is mostly fluid, nigh useless. You can elicit sarcoplasmic adaptation through high reps, low intensity. Think body building. Myofibrillar is actual functional mass, i.e. a farmer who bales hay all day every day. So, in the end, make sure the ...

If your goal is general fitness then you're doing plenty of running, walking, and swimming, but your deadlift is quite light. Sixteen reps is also a lot for the deadlift. If it's possible to use more weight but fewer reps per set, do that. 60kg to 100kg should be entirely doable for you within a few months. Other ways to get good use out of your limited ...

There are a few things you can do: When I start running and start to feel pain I decrease my speed and focus on my running form. If the pain doesn't stop after 1000-2000 meters I simply stop running. Probably you don't do the warming up the way you need to. Check for some foam roller exercise. You can do them with big glass bottle like wine one too. You ...

At 8 I would not worry about it. She hasn't even hit her growth spurt yet. If she is still slower than others by 11, then worry about it. Many parents had their kids doing all sorts of speed training at 4-8 and by the time the kid is 12, are out of sports due to injury.

There are two main ways to decrease the size of a muscle; Don't use the muscle Or at least use it only when necessary. If you don't use the muscle, it won't be hypertrophied. From there, it could remain at its current size, or decrease in size (atrophy). Overuse the muscle (not recommended) Basically, if you use the muscle a lot, but don't provide it ...

Like @Mårten said, you either lose fat over your entire body, or nowhere at all. You can't pick and choose where to gain/lose fat. As for losing then gaining weight, the difference lies in your diet. You mention that you dieted when you lost weight, and after that you started to gain weight again. This should be a telltale sign. And it's a well-established ...

You cannot burn fat in a specific location, legs do not use only leg fat, and so on. If you want less fat on your legs you will need to reduce fat overall.

I have a counter-question for you. If running doesn't work for you, but biking does, why suffer trying to run more than you can? I can't claim that cycling will have a lot of carryover into running (it might initially), but it is a very effective way to get aerobic exercise. Like most physical activities, starting too hard, too quickly can be detrimental ...

I have been working out with the Suunto Foot Pod Mini since 2012 and I have to admit that I love this gadget. It measures your current speed and distance and is compatible with the HR monitors (watches) from Suunto (e.g. Suunto t6d or Suunto M5) and quite accurate (measured 31,3km on a 31,1km run, I think that is an acceptable deviation). Furthermore it does ...

Dont get wireless head phones. Just get some head phones that have a plastic part that hooks around your ear. Then the cords can be heavy and even flop around or get pulled on while being under your shirt without falling off. These dont need to be expensive, so check out Marshalls or TJ Max.

I asked this question a year ago and it got blocked/edited/removed! I figured out on my own after reading some books on running form, or at least an idea of why not to do this: The energy lost due to carrying weight like the two other answers said. The weights seem to spread out my stride while slowing down my cadence. A similar gain in stride seemed ...
