Many recent studies have reported that resistance training can be effective in producing strength gains, altering body composition, enhancing sport performance and reducing rate of injury in children. The strength gains in children can be influenced by factors such as neurological adaptation, motor coordination, frequency and time of the training programme, but not muscle hypertrophy. In the past, resistance training was not recommened for prepubertal children, because of lack of sufficient quantities of circulating androgenic hormones and potential for damage to growth plates. Current research indicates that resistance training can be safe for children provided that qualified supervise, appropriate load, proper lifting and safe training guildlines. Conclusion, given proper supervision and appropriate program design, children participating in resistance training can increase muscular strength and don't appear to be at any risk of injury.
