Effects of a circuit training programme on agility and reaction time of non-athletes in Port Harcourt, Rivers State

Abstract

This study examined the effects of a 10-week circuit training program on agility and reaction time in 60 non-athlete university students. Participants were randomized to either the experimental group (n=30) that completed progressive circuit training 3 days/week for 10 weeks, or a control group (n=30) that maintained usual activity. Agility (Illinois Agility Test) and reaction time (ruler drop test) were measured pre- and post-intervention. There was a significant group x time interaction for agility (p=.016), with the experimental group demonstrating a mean 9.48 sec faster agility time from 31.07-sec pre-test to 21.59-second post-test. In comparison, the control group showed minimal change (pre: 26.03 sec, post: 26.27 sec). However, changes in reaction time were non-significant (p=.367), although the experimental group exhibited a slight 0.03 sec decrease versus controls. In conclusion, circuit training is an efficient, effective exercise modality that improves agility regardless of baseline fitness. Optimal configurations maximizing adaptations warrant identification. The recommendation is to introduce tailored circuit training programs, possibly extending their duration to improve reaction time, particularly among special populations. It is urged to widely promote the adoption of these programs in both athletic and clinical settings.
