Comparison of the effects of two types of progressive muscle relaxation (7 and 16 muscle groups) on selected psychophysiological and psychomotor parameters following repeated sub-maximal intensity exercise in young athletes

摘要

Kajian ini bertujuan untuk membandingkan kesan dua jenis teknik relaksasiudotot berperingkat (7 dan 16 kumpulan otot) ke atas parameter psikofisiologi danudpsikomotor terpilih selepas latihan berintensiti sederhana tinggi. Dua puluh enamudorang remaja lelaki aktif dengan purata umur 13.4 ± 0.5 tahun, berat 50.8 ± 8.1 kg,udBMI 19.2 ± 1.7 kg.m ¹, VO2max 54.48 ± 6.67 ml.kg ¹.min ¹ and HRmax 201.7 ± 1.5udbpm telah mengambil bahagian dalam ujikaji ini. Mereka dibahagikan secara rawakudkepada kumpulan kawalan (n = 8) dan dua kumpulan intervensi: ‘ProgressiveudMuscle Relaxation (PMR)’ 16 kumpulan otot (n = 9) dan ‘Progressive MuscleudRelaxation (PMR)’ 7 kumpulan otot (n = 9). Setiap peserta dinilai dalam tiga sesiudujian; permulaan intervensi, pertengahan intervensi (selepas 6 sesi latihanudrelaksasi) dan akhir intervensi (selepas 12 sesi latihan relaksasi).ududThe present study was undertaken with an objective to compare theudeffectiveness of two types of Progressive Muscle Relaxation (PMR) (7 and 16udmuscle groups) on selected psychophysiological and psychomotor parametersudfollowing repeated sub-maximal intensity exercise. Twenty six physically activeudyoung males with the mean age 13.4 ± 0.5 years old, weight 50.8 ± 8.1 kg, BMIud19.2 ± 1.7 kg.m ¹, VO2max 54.48 ± 6.67 ml.kg ¹.min ¹ and HRmax 201.7 ± 1.5udbeats.min ¹ participated in this study. They were randomly assigned to the controludgroup (n = 8) and two intervention groups: 16 muscle groups Progressive MuscleudRelaxation (n = 9) and 7 muscle groups Progressive Muscle Relaxation (n = 9).udEach participant was tested in three experimental sessions; pre-intervention, midinterventionud(after 6 sessions of relaxation training) and post-intervention (after 12udsessions of relaxation training).ud
