摘要:
BACKGROUND:In isokinetic testing researches,the effect of sport training on the development of teenager muscle groups is less reported. OBJECTIVE:To assess the muscle strength of shoulder,hip and knee joints in different teenager populations with isokinetic testing system. DESIGN,TIME AND SETTING:The contrast observation was performed at the laboratory of Institute of Physical Education,Hebei Normal University between October and December 2006. PARTICIPANTS:Control group included 30 volunteers without sport training randomly selected from four middle schools in Shijiazhuang,15 male and 15 female;training group included 30 volunteers with sprint training randomly selected from Shijiazhuang Sports School,15 male and 15 female. METHODS:We used Kinitech isokinetic testing system(Kylingk,Austrilia) to test the shoulder,hip and knee joint of the 60 participants according to 3 different angular velocities:60( ?) /s,120(?) /s and 240( ?) /s. MAIN OUTCOME MEASURES:Peak torque(PT) values of extensor and flexor groups in shoulder,hip and knee joints. RESULTS:The 60 volunteers were all included in the result analysis. PT values of shoulder joints were bigger in the male training group than in the control group at 60( ?) /s,120( ?) /s and 240( ?) /s(P 0.05) ;PT values of hip joints were bigger in the male training group than in the control group at 60( ?) /s,120( ?) /s and 240( ?) /s(P 0.05) ;PT values of knee joints were bigger in the male and female training group than in the control group at 60( ?) /s,120( ?) /s and 240( ?) /s(P
