Abstract: (301 Views)

Background & Aims: Electrical activities are required for muscular contractions and physical activities. Understanding the electrophysiological attributes of the upward and downward phases of squats and lying leg raises provides a strong scientific basis for modifying physical exercises to suit specific fitness and rehabilitation goals. The aim of the study was to determine the effects of the upward and downward phases of squats and lying leg raise work-outs on electroencephalograms and electrocardiograms in healthy male individuals.
Materials & Methods: Ten healthy young adult males averaging 19.6 of age and meeting the inclusion criteria were selected. Squat and lying leg raise work-outs were conducted at a rate of 12 reps per minute. Electroencephalograms and electrocardiograms were recorded using the PowerLab 26T system.
Results: The study results showed that during the downward phase of squat work-outs, beta wave frequency was higher compared to the downward phase of lying leg raise work-outs. Both the upward and downward phases of squat work-outs caused a reduction in alpha/beta and alpha wave frequencies compared to the corresponding upward and downward phases of lying leg raise. Additionally, the downward phase of squats resulted in a lower RR interval than the upward phase.
Conclusion: The findings of the study highlighted the electroencephalographic and electrocardiographic characteristics of the upward and downward phases of squat and lying leg raise work-outs in healthy male individuals. Compared to the downward phase of lying leg raises, the downward phase of squats was characterized by higher beta wave frequency, lower alpha wave frequency and a lower alpha/beta ratio. The downward phase of squats elicited greater cortical activation relative to lying leg raises.
