Method: 51 students aged 12 – 14 years of Birbhum district, West Bengal, India have been tested on three physical fitness components namely; speed (50 Mt. Dash), agility (Semo agility test), explosive strength (standing broad jump) and reaction time (Nelson Hand Reaction Test). Pearson Product Moment Correlation Coefficient method has been used to find out the relationship.

Result: The result showed no significant relationship between all the three physical fitness components with reaction time with ‘r’ value of 0.053 (speed and reaction time), 0.029 (agility and reaction time) and -0.16 (explosive strength and reaction time).

Conclusion: The result may be due to lower level of physical fitness, socio economic status, physical activity, lifestyle etc. of the selected students.
