Abstract:

BACKGROUND: It has been shown that different types of exercise can enhance bone mineral density in different degrees.
OBJECTIVE: To investigate the effect of volleyball exercise on bone mineral density in females and its age and side differences.
METHODS: Totally 112 participants were divided into young experimental (n=20) and control (n=20) groups, middle-aged experimental (n=20) and control (n=18) groups, and elderly experimental (n=18) and control (n=16) groups. The participants in each experimental group were the female volleyball teachers or those females who performed long-term volleyball exercise, while those in each control group were female teachers, but almost no contact with volleyball. The bone mineral density of the bilateral distal radius 1/3 and L2-L4 vertebrae was measured using Prodigy type Advance dual energy X-ray absorptiometry produced by the United States GE company. Independent-Sample T Test and one-way ANOVA were performed on SPSS 20.0 software.
RESULTS AND CONCLUSION: The bone mineral density of the radius in the experimental groups was significantly higher than that in the control groups at each age bracket (P < 0.05). The L2-L4 bone mineral density in the elderly experimental group was significantly higher than that in the elderly control group (P < 0.05). The observation indexes were significantly different in the elderly and the other two age bracket groups (P < 0.05). These results imply that volleyball exercise has a positive effect on the bone mineral density of radius especially the right radius and lumbar in females. The effect of this exercise on the bone mineral density of radius is different between two sides due to different exercise loads on two arms and lumbar spine in females. Moreover, volleyball exercise can effectively delay the loss of bone mass in the older adults.
