I think that in body building, one exercises to the point of injury of
muscle fibers and the body's repair leads to bigger better muscles.
When does this become a negative, with injury to the muscle producing
fibrosis rather than hypertrophy? Body building techniques work to
some extent in older patients, but they maintain strength rather than
getting bulging biceps.
For skeletal muscle, too much exercise may not be that serious, but
what about heart patients? Exercising to reach a target heart rate
may be further injuring an already damaged heart. Do too little exercise
and nothing happens.
