Integrative neuromuscular training protects juvenile female athletes from knee injury / 中国组织工程研究

ABSTRACT

BACKGROUND: Compared with single proprioceptive training and simple neuromuscular training in the trunk and hip, the integrative neuromuscular training possesses comprehensive effect, which not only prevents sport-induced knee injury, but also improves the athletes' sport ability.OBJECTIVE: To validate whether the integrative neuromuscular training can enhance sport quality of juvenile female athletes and improve biomechanical pattern of the lower limb when jumping.METHODS: Eighteen juvenile female tennis athletes were selected and randomized into experimental and control groups. The athletes in the experimental group received 8-week integrative neuromuscular training and technical training involving the strength of the lower limb, core stability, plyometrice training, dynamic equilibrium, agility and speed. Those controls were subjected to 8-week traditional physical training and technical training. The vertical jump dynamic equilibrium, agility and biomechanics of the lower limb were measured at 1 week before intervention and 7 weeks after intervention to quantize the effect of integrative neuromuscular training on the sport ability and prevention of knee injury.RESULTS AND CONCLUSION: The vertical jump, agility, overall stability index, the knee extension angle as well as knee adduction and abduction moment in the experimental group were significantly improved (P < 0.05). Integrative neuromuscular training cannot only enhance the explosive strength of the lower limb, dynamic equilibrium, and agility when juvenile female athletes exercising, but also improve the biomechanics of the lower limb when jumping, increase the knee extension angle, and reduce knee adduction and abduction moment
