en Electrophysiological analysis of the upward and downward phases of squat and lying leg raise work-out عمومى General پژوهشي orginal article 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.  Alpha wave, Beta wave, Electrophysiology, Lying leg raise, RR interval, Squat 107 114 http://ijrabms.umsu.ac.ir/browse.php?a_code=A-10-439-1&slc_lang=en&sid=1 Mayowa Jeremiah Adeniyi 7jimade@gmail.com 10031947532846003913 10031947532846003913 Yes Department of Physiology, Federal University Health Sciences Otukpo, Nigeria Ayoola Awosika ayoolaawosika@yahoo.com 10031947532846003914 10031947532846003914 No College of Medicine, University of Illinois, USA Samuel Agaba Ameh Samuel.ameh@fuhso.edu.ng 10031947532846003915 0009-0005-0770-5227 No Department of Physiology, Federal University Health Sciences Otukpo, Nigeria John Obogwu john.obogwu@fuhso.edu.ng 10031947532846003916 0009-0009-6715-5860 No Department of Physiology, Federal University Health Sciences Otukpo, Nigeria Samuel Ijoganu ijoganusam@gmail.com 10031947532846003917 10031947532846003917 No Department of Physiology, Federal University Health Sciences Otukpo, Nigeria Phoebe Nwamaka Kanikwu nwakanikwu@gmail.com 10031947532846003918 10031947532846003918 No Department of Nursing, Edo State University Uzairue, Nigeria
