Abstract:
Objective:To explore the effect of aerobic plus resistance training on the intervention of adolescents with moderate mental retardation and to provide reference for healthy development among specific need population.
Methods:Totally 29 adolescents with moderate mental retardation, aged 12-17 years from one middle school in Shunde district of Foshan, were divided into intervention group and control group (16/13) with random number table. The intervention group was subjected to aerobic combined resistance exercise for 11 weeks. The control group maintained the original activities. The changes in body composition, muscle strength, cardiorespiratory endurance and balance ability of the two groups of subjects before and after intervention were compared.
Results:After the intervention, the intervention group s skeletal muscle (22.90±3.63)kg, muscle mass (39.75±5.57)kg, lean body mass (41.52±6.79)kg, sitting arm support (49.19±35.28)s, standing timing test (22.13±6.01)s, half crunches (20.12±6.48), grip strength [left (15.98±4.86)kg; right (16.37±5.46)kg], heart rate immediately after 2 min stepping exercise (91.43±13.44)frequency/min, Standing on one foot with eyes closed [left (5.82±5.20)s; right (6.02±5.56)s] compared with before exercise, the body fat decreased(t=2.57,2.72,2.07,2.10,3.31,2.92,2.76,3.44, 2.86,2.04,2.38, -2.92,P<0.05); after the intervention, the sitting arm support and closed eyes standing(right) improved(P<0.05).
Conclusion:Aerobic combined resistance exercise can improve muscle strength and endurance, aerobic endurance and balance ability in adolescents with moderate mental retardation and adaptability of teenagers with moderate mental retardation.
