Outline of Final Research Achievements

We examined the investigation between the results of muscle training and bone composition in university athletes, using an ultrasonic bone densitometer to observe changes in bone during the training process. Observations of changes in muscle and bone during the training process revealed that weight training focused on physical strength was significantly correlated with cortical bone thickness, and weight training focused on power was significantly correlated with cancellous bone density. We will continue to investigate changes in bone composition due to differences in sporting activities and training methods in future, mainly by means of ultrasound densitometer.
