The effect of external intervention (different rhythms of music) on some of physical fatigue indices in healthy young females

The aim of this research is to study the effect of external intervention (music) on some of physical fatigue indices in healthy young females . In order to do this study , 38 healthy female students randomly allocated in 3 groups include fast music group or EXPI (N=13 ,M±SD:22±2 years), slow music group or EXP2 (N==13 ,M± SD:23 ± 2 years) and control group (N=12,M± SD:23 ± 2 years). In each session, training program consists of pedaling on ergometer cycle was executed in a 20 watt power with 50 R.P.M, then after each minute, 10 watts was added to workload so that they became exhausted. Training program continued for 6 weeks and two sessions per week. The experimental groups were doing the training as they listened to music by headphone. The EXPI group listened to fast music (Allegro Assay of Mozart by the rhytlun of ){ and the speed of 180 metronomes) and The EXP2 group listened to slow music (Adante of Mozart by the rhythm of 12 and the speed of 60 metronomes) and control group received no musical intervention. Data analysis by ANOVA showed that the pretest differences between fatigue indices in three groups was not significant (P>0.05). But also post test of final workload of subjects (p= 0.022) , HR of exhaustion (p= 0.013) and time to reach exhaustion (p= 0.028) between groups were significant. The post hoc of Tukey showed that there were significant differences between experimental groups with control group in all variables (PO.05).
