1. Muscle Cross Sectional Area - there is a strong Fnsitive relatiensh:- betn'een -n.cle CSA and strensth'' Muscles increase in strength by increasing their size and by enhancing the recruitment and firing rates of their motor units. I Hypertrophy - an increase in size of a cell such as a muscle fiber Hyperplasia --an increase in nffi6riTGiis such as muscle fibers. -'' ll \r"" - Current research indicates that muscle fiber h-tpertrophy accounts for most, if not all, of the increase in muscle cross-sectional area due to an overload training program. There is evidence that muscle fibe_r hyperplasia occurs in animals, but there is presently no direct evidenqe that it occurs in humans. 2.

Unformatted text preview: Ihq _strenqth to mass ratio directlv reflects an athlete's abiliw to accelerate his or her . body. All else being equal, smaller athletes are stronger pound for pound than larger-athletes. ln comparing performances of Olympic weight-lifters in different weight categories, the most widely used formula is to divide the weight lifted by body weight to the2l3 power. LargQ athletes dominate sport events which requirg,a-ligh level of absolute strength (e.g.ithrowing events in track and field) while sgr_{!e_r athletes dominate sport events w'hich require a high strength/body mass ratio (e.g., gymnastics). 3.
