การเปรียบเทียบผลของการฝึกเต้นแอโรบิกบนมินิแทรมโพลีนในร่มและกลางแจ้งต่อการสลายมวลกระดูกและวิตามินดีในหญิงวัยทำงาน / ไชยวัฒน์ นามบุญลือ = A comparison between the effects of indoor and outdoor mini trampoline aerobic dance training on bone resorption and vitamin D in working women / Chaiyawat Namboolu
The purpose of this study was to compare the effects of indoor and outdoor mini trampoline aerobic dance on bone resorption and vitamin D levels in working women. The simple random sampling method for this study consisted of 54 female volunteers from Chulalongkorn University aged between 35-45 years. The subjects were divided for 3 groups include 17 females training indoor, 17 females training outdoor mini trampoline aerobic dance training groups and 20 females in the control group. The training group participated on a mini trampoline aerobic dance exercise program while wearing heart rate monitor during exercise. The aerobic dance on mini trampoline by rhythm of the music. All experimented group trained for 3 times per week, 40 minutes a day and training for 12 weeks. The intensity was 60-80% of the maximum heart rate. The control group did not participate in the mini trampoline aerobic dance exercise program. The data were collected both before and after the experiment. The collected data were biochemical bone markers (β-CrossLaps and P1NP) and vitamin D levels (25(OH)D). The obtained data from pre and post training were compared and analyzed by paired samples t-test and analysis of covariance, by using test a significant difference at .05 levels.
The results of this study were followed, after 12-week of training, the biochemical bone markers in the indoor and outdoor mini trampoline aerobic dance training subjects after the training intervention was significantly lower in bone resorption (β-CrossLaps) and bone formation (P1NP) had no significantly difference between the experimental group (Indoor and outdoor mini trampoline aerobic dance training) and control group (p≤.05). Besides, the calcidiol levels (25(OH)D) in the outdoor aerobic dance training subjects after the training intervention was significantly higher when compare between indoor mini trampoline aerobic dance training and control group after the training intervention (p≤.05). Conclusion, the mini trampoline aerobic dance training has the positive effects on biochemical bone markers. In addition, the outdoor mini trampoline aerobic dance training increasing the vitamin D levels and reduce the risk to osteoporosis and new alternative exercise programs for working women.
