Abstract


Introduction: Badminton is a racquet sport. At a higher level game, being a fast paced sport Badminton demands excellent fitness, aerobic stamina, strength, speed and precision. [1] Playing Badminton also requires good agility, cardiovascular endurance, strength and reaction time. Reaction time is the amount of time taken to respond to a stimulus. It can be improved by practice as it affects the quality of game. [3] Every player and healthcare professionals need to analyze the technique and requirement of the sport in order to modulate the coaching accordingly.  

Aim: To find if there is a correlation between upper extremity muscles strength of dominant hand and reaction time in competitive badminton players.

Material and Method: Isometric muscle strength of pectoralis major, shoulder rotators, triceps, deltoid, wrist flexors and extensor were assessed using the hand-held dynamometer (FET3) and the reaction time was assessed by audio-visual reaction time machine.

Findings: The strength and reaction time of competitive badminton players was assessed of which 7 were males and 30 females. The average age was 18.77 (± 2.75). Both the parameters were correlated by the Pearson’s correlation coefficient test using Microsoft Excel 2007. A negative moderate correlation was found between the upper extremity muscle strength and reaction time. This shows that when the strength of an individual is greater, then, the reaction time is lesser.

Conclusion: This study concludes that there is a negative moderate correlation between the upper extremity muscles and visual reaction time in competitive badminton players, which means that muscle strength, can affect the reaction time to some extent, i.e. strength and reaction time of the dominant upper extremity muscles are directly proportional.
