The effect of Therapeutic exercises and plus whey protein in hamstring tear treatment of volley ball players

The purpose of the study was to determine the role of rehabitaion exercises and whey protein in hamstring tear treatment of volley ball players injured with hamstring minor tears , they were diagnosed and divided to two equal groups (14volley ball players), Age between (18 : 23Y) ,group 1 treated with rehabitaion exercises and group 2 treated with rehabitaion exercises plus whey protein (30 grams) , twice daily, healing time , AST,ALT,UREA, creatinine concentrations, CPK, SOD, cortisol, together with isotonic leg muscle strength and pain scale were performed before and after rehabitaion exercises and exercises plus whey protein was detected . Blood sample (5 ml) was drawn for biochemiecal tests ,muscle strength was evaluated using dynamometer, pain test was evaluated, rehabitaion exercises were executed in three phases , one week each, the first stage was in negative rest and in positive rest during the other two stages after the suggestion of
specialists insport medicine, whey protein capsules (30gr,twice/daily), were ingested daily for three weeks. results revealed a reduction of protein metabolites in the two groups with a further decline after whey protein ingestions in case of muscle strength , there was a significant increase after whey protein ingestion plus exercises compared to rehabitaion exercises , also decreased creatine phosphokinase (CPK), aspartate, alanine transamilnase (AST,ALT) .In conclusion , whey protein administration induced faster healing time and a higher muscle strength together with lower pain test , it is recommended to use a supplement as whey
protein for the process of muscle healing together with the rehabitaion exercises.
