The physical condition of a muscle is determined by its freedom from fatigue, its temperature, its stores of energy foodstuffs, its state of training and its ability to recover from bouts of work. Fatigue reduces the excitability, power and extent of contraction of muscle. Unless the stimulus is great fatigue reduces the number of fibers which respond in repeated muscular contractions. Such reduction in the number of contractile elements reduces the power of the contractions.
It’s a nice thought—and people definitely try. But, sadly, you can’t exercise off a crappy diet. Science backs it up. In one study—literally entitled: “It is Time to Bust the Myth of Physical Inactivity and Obesity: You Cannot Outrun a Bad Diet”—published last year in the British Medical Journal, researchers confirmed this, and also argued the over-emphasis on physical exercise at the expense of dieting encourages manufacturers to create a “health halo legitimization of nutritionally deficient products.”
The mechanical action of the levers employed determines the power which the muscle must exert to perform the work. Two factors influence the amount of power which a muscle can supply to its lever: variation in the strength of the pull resulting from different degrees of stretch of the working muscles and the mechanical advantage of the lever. The position of a muscle at contraction affects the strength of the pull of the muscle. The position of greatest pull is one in which the muscle is slightly stretched.
A girl wants to be beautiful; a boy desires to be strong, with a nice-looking physique. These are natural desires-they are ranked at the top of the list as highly valued possessions by youth themselves. Providing that no pathologic condition is involved, a strong physique can be obtained in a comparatively short period of time.
As long as caloric requirements are met and the diet is balanced, there is nothing terribly wrong with three meals per day. On the other hand, mare frequent small meals (4-6 per day) may reduce feelings of hunger and prevent binge eating. Another argument favoring more frequent meals is the fact that food itself stimulates basal metabolism in most individuals.
I love the country from which I’m from, but we have to many fast food joints and restaurants, no one eats home cooked meals anymore. It makes it so hard to make good healthy meals for yourself when you pass by a million places in a row on one street and you can smell the food!
