<b>A Comparative Study of Weight Training and Power Lifting in School Children below 19 Years</b> Strength training in children, in combination with plyometric and or agility training, has become an increasingly popular tactic for school children below 19 years to gain a competitive edge in weight training and power lifting during the off season. Children can improve strength by 30 to 50 after just 8 to 12 weeks of a well designed strength training program. Youth need to continue to train at least 2 times per week to maintain strength. The case reports of injuries related to strength training, including epiphyseal plate fractures and lower back injuries, are primarily attributed to the misuse of equipment, inappropriate weight, improper technique, or lack of qualified adult supervision. Children who establish regular exercise habits will ideally continue them into adulthood. strength, children, weight training, power lifting, school, exercise, supervision 21-25 Issue-6 Volume-6 Dr. Yashpal Singh Bhati
