Energy consumption of our body

If running can give forrest gump a new life, it will atleast make you happy.

1) You burn more fat when you`re walking than when you`re running
FALSE. For example, you may burn 30% fat and 70% carbs when you run, and 50% fat and 50% carbs when you walk, however, since you burn more energy while running, you end up burning more fat absoltuely.

2) A person who walks 2 km burns the same energy as those who run 2 km.
FALSE. When you run, you definitely spend more energy. The energy spent depends on the speed at when you run. It`s a non-linear graph. Even though the work done is equal on the body, muscular motions dissapate most of their energy as heat, when you run. A much more efficient way to travel 2 km is by cycling, you would agree..

3) It is necessarily to become breathless to lose weight.
FALSE. Infact, one of the tests that you are jogging well, is to check whether you can speak properly.
Breathlessness depends on the power that can be delivered by your cardiovascular system to your muscles(lack of which generates lactic acid). Losing weight is a matter of total energy expended.

I use this tactic: Jog at the speed I don`t become completely breathless, for the whole journey, except for the last 200 metres, when I sprint.

4) Weight training is difficult after cardiovascular training
FALSE. You have glucose reserves of around 2500 kcal in your liver, which is the energy used during one day. Until this energy is fully exhausted, you do not become actually tired. Till then you feel tired only because of lactic acid generation, which relieves itself in minutes.

Infact, in order to keep as much of glycogen possible in the liver, marathon runners load themsleves up with carbs the night before the race.

5) It is necessary to take high protein diet for weight training.
This is one question that I am asked often: What extra do I need to eat. Well, if you`re just beginning, I would suggest: don`t bother about it.
You already take enough protein to build your muscles, which is just converted into carbs (and the extra urea excreted). So, taking extra proteins will just make you fatter. However, as your muscle mass builds up, they need upkeep proteins, and a month into body building, you can start worry about it.

In short: Worry about exercising, not about eating, cause eating is the easier thing to do.

6) Your muscles will keep building up at a linear rate.
FALSE. After a certain mass, your muscle building reaches an asymptote. Then you have to concentrate on diet while maintaining workouts. It does increase slowly then...

7) You feel hungrier when you work out.
I have never felt so. Infact, I`ve felt like eating lesser.

8) If you stop exercising your muscle degrades very quickly
It depends on the person, but in my opinion, there is a lot of hysterisis.

9) I need to eat meat to be a body builder
False. You get all the proteins you need from pulses and milk. Infact, you will take some time to need more proteins than you already eat. You are not a grey wolf.

10) Massaging decreases muscle pain duration
There is no evidence, against or for.

11) Body building is bad for the bones
FALSE. body building increases bone density a lot. The only thing you have to care about is your back, and do care about it well. If you have chronic back problem, do consult the net before embarking on exercises wihch compress or bend it. Posture is very important, and your back should always be straight.

12) I am thin, so I should do weight training
FALSE. There is no need to run, but weight training can improve your looks a lot.

13) The sudden improvement I notice in strenght is due to the build up of muscle.
FALSE. The first reactino of the body in weight training is to improve the neural system aroundt he muscles, and during cardio vasuclar training is the improve power transfer mechanisms of the blood to transfer oxygen. These have decently quick effect.

14) If I starve I will lose weight
True. You lose around one third to half kilos of weight every day of starvation. However, when the urge comes to eat, it is much larger. People tend to oscillate around their reference weight (the weight they consider ideal). More radical weight loss plans have larger oscillations.

15)Don`t neglect lower body strength. It`s very essential. The best way to improve is to do sit ups. with or without weights. Dont`forget that your quadriceps are the largest muscle mass in the body. and can make a large difference in your metabolic rate, your walking confidence and stuff like that

16) More muscle mass means more metabolism:
TRUE. But the effect is not very signficant.

17) Making larger quadriceps lets your run longer.
I`ve not noticed a difference. Actually when you run long distance, your quadriceps are not used too much. It`s your calves and feet muscles. Even they are not often used to their full power.
Much more important for your long distance running is 1) Your weight 2) Your cardiovascular system 3) Your ability to think from your head
