Does this now mean that we are justified in recommending that children not be allowed to run, jump, throw or catch because biomechanical research definitely shows that such activities can produce very large forces on many parts of the growing body? <br>It should be obvious then that there is nothing wrong with running and other normal activities of childhood, and therefore no reason to disallow activities of lesser impact, such as carefully structured programs of weight training.<br>Siff also notes that bone density scans have proven that youngsters who do competitive weightlifting (i.e., the snatch and the clen and jerk) have higher bone densities than children who do not use weights, and that clinical research has not shown any correlation between weight training and epiphysial damage. Further, an extensive Russian study on young athletes, published in a book entitled School of Height, concluded that heavy lifting tends to stimulate bone growth in young athletes rather than inhibit it.<br>Two possible reasons for the fear that weight training could stunt growth are that weightlifters tend to possess more muscle mass than other athletes and that smaller athletes are attracted to the sport. In gymnastics, the average height of elite athletes has steadily declined in the past several Olympics because shorter athletes tend t
