HIT uses far more of our muscle tissue than classic aerobic exercise. When you do HIT, you are using not just the leg muscles, but also the upper body including arms and shoulders, so that 80% of the body's muscle cells are activated, compared to 20-40% for walking or moderate intensity jogging or cycling. Active exercise also seems to be needed to break down the body's stores of glucose, deposited in your muscles as a substance called glycogen. Smash up these glycogen stores and you create room for more glucose to be sucked out of the blood and stored. Although 15% of people made huge strides (so-called "super-responders"), 20% showed no real improvement at all ("non-responders"). There is no suggestion that the non-responders weren't exercising properly, it was simply that the exercise they were doing was not making them any aerobically fitter. This can be in 3 minutes of exercise!:happy
Can you make a relevant point in one of your posts instead of posting random, pointless information that everyone here has been aware of for years?
If you are working your muscles at the level of resistance that being a stress that the body normally encounters ie running, walking cardio then this isn't sending the body the message that it needs to change to adapt in order to be able to handle in the future. Look at this from an evolutionary stand point and that is for a few million years the only time we worked that hard is when we were trying to kill some thing or something or someone was trying to kill us. most kills happened in 3 minutes, so the mistakes that most people do is too much training and to often hurting the body. So think about it if you train as hard as you need too you'd have to cut your volume. Remember training is not about how much the body can tolerate i.e "Rocky" but minimal training for maximum results.
A few things - 1. Congratulations on discovering how evolution works and how the human body adapts to new stresses. As I stated earlier, we all already know this so why you are typing out all of your findings I don't know. 2. The context you're using is irrelevant. Yes we evolved to hunt, sprint, throw things, kill things etc but that is in no way relevant to boxing conditioning. If you honestly believe you'd be able to content in a boxing match with 3 minutes high intensity training a few times a week then you really don't know what it takes. Again, that was a study to see how much overweight guys could improved their fitness. If you have a match please try this protocol and have it recorded so we can watch you fail. :rofl
Virus do you think that you could sit out in the sun and tan until your skin is black with out burning?
