Factors Affecting Strength Performance. The display of maximum strength depends on three main factors:
1. MUSCLE POTENTIAL
This is the sum of forces performed by all the muscles involved in a movement According to Kuznctsov (1975) and Baroga (1978) the potential to perform force is 2.5-3 times higher than the contemporary performances in weight lifting.
Thus, on the basis of these claims an athlete should be able to lift a weight of up to 800 kg, which obviously is much above current performances.
2. THE UTILIZATION OF MUSCLE POTENTIAL
This refers to the ability to utilize simultaneously many muscle fibers, both central and peripheral. The ability to elevate the utilization of muscle potential is substantially facilitated by employing specific exercises of both natures: defeating and opposing gravity, in addition, exercises performed in a rhythm superior to that of a competition, a high volume of work, and a wise utilization of isometric with dynamic contractions arc considered effective.
A muscle that has an in vitro potential to lift 100 kg is physiologically limited to 30% of its potential (Baroga, 1978) or 30 kg. As previously suggested from a theoretical potential of 800 kg a weight lifter may lift a load of about 240 kg.
However, through a specific training aimed at improving the utilization of muscle potential, technique used as an intermediary, may serve to improve athletes ability to lift a weight up to 80% of his/her maximum potential.
As a result, weight lifters should be able to lift 640 kg and high jumpers to perform 2.60 2.70 m. It seems that the possibility to achieve such performances lies on the ability to involve simultaneously in activity, central and peripheral muscle fibers (Kuznetsov, 1975).
