Effects of Low Impact Aerobic Dance and Fitball Training on Bone Resorption and Health-Related Physical Fitness in Thai Working Women.

Abstract

OBJECTIVE:

To investigate the effects of low impact aerobic dance and fitball training on bone resorption in Thai working women.

MATERIAL AND METHOD:

The samples of this study consisted of 47 females at the age from 35-45. The subjects were divided into two groups: A) 23 females in a low impact aerobic dance (20 min) and fitball (15 min) training group, and B) 24 females in a low impact aerobic dance training group (35 min). Both groups wore a heart rate monitor during the exercise training. The sessions in the training program over 12 weeks were performed a 3-day a week, 35-minute for work out per session at an intensity of 60-80% of maximum heart rate. Before and after the 12-week training program, bone resorption (Telopeptidecrosslinked: β-CrossLaps) and bone formation (N-terminal propeptine of procollagen type 1: P1NP) including physiological and fitness data were assessed. The data of pre and post trainings within and between the groups as well as the data of changes in dependent variables were compared and analyzed by using paired t-test and independent-test. The statistically significant difference was set at the 0.05 level.

RESULTS:

Both the low impact aerobic dance and fitball training group and the low impact aerobic dance training group revealed their lower level of bone resorption (β-CrossLaps) while the first group showed statistically significant change (p < 0.05). In addition, there were no significant changes of bone resorption (β-CrossLaps) and bone formation (P1NP) between these two groups. However; both groups had not only a significant decrease in resting heart rate, systolic and diastolic pressure, but also an increase in muscular strength and endurance and maximum oxygen uptake when the training was completed. Flexibility ofthe group withfitball was increased significantly (p < 0.05).

CONCLUSION:

Low impact aerobic dance and fitball training has the positive effect of slowing down bone resorption and is beneficial to healthy bones. They concurrently increase lower back flexibility.
