Abstract
  • This study explored the relationship between strength, physical activity, and fractioned reaction time. This study also examined the influence of gender on these relationships. The variables examined included peak strength, relative strength, pre-motor time, electromechanical delay, and total reaction time. A sample of 12 males and 12 females, 18-29 years old, performed five trials of a maximal voluntary isometric contraction in the hamstring muscle group to determine strength and fractioned reaction time. A significant inverse relationship between peak strength and total reaction time was observed (r = -0.455, p = 0.026). Additionally, a significant inverse relationship was observed between relative strength and total reaction time (r = -0.448, p = 0.028). No other relationships examined were significant. Gender significantly influenced the relationships between peak and relative strength and TRT by rendering the correlations non-significant but no other gender influence was observed. These findings suggest that stronger individuals will display shorter reaction times.
