When posture changed from maximum flexion, through neutral, to maximum extension, the span with better MVC output seems to move from a smaller span to a larger span. as T-level, it took more time on the later period of exertion. 20 subjects participated in Eexperiment 2 in which MVC and time needed to reach different levels of exertion were measured using 3different kinds of gloves.results indicate that femal performed MVC was 55% of male and wearing gloves decreased the MVC of grip .
