Is Simple Reaction Time Influenced by Arm Span, Neck Length and Arm Span to Height Ratios of individuals?

Background: Aims: The purpose of this study was to examine the relationship between arm span, neck length and arm span to height ratio (AHR) with simple reaction time (RT). Methods: The study was conducted amongst 501 (232 females and 269 males) untrained University of Cape Coast students whose ages ranged from 17-29 years. Results: In this study it was found that there was significant correlation between AHR and RT in both males and females, there washowever no significant correlation between arm span nor neck length of participants and RT. Conclusion: AHR appears to significantly correlate with simple reaction time, but the direction of correlation appears to differ in males and females
