| Summary: | 碩士 === 國立屏東教育大學 === 體育學系 === 100 === The primary purpose of this study was to examine the effects of 12 weeks upper body vibration training on bone muscle strength and muscle damage in underweight female. Thirty-five subjects were recruited from NPUE female students with lower body mass index (BMI＜18.5) at the age between 19 to 22 and were no injured in upper body in the past one month. Subjects were randomly assigned to training group T1(n=8), T2(n=7), T3(n=6), T4(n=7) and control group (n=7). Training groups proceed experiment by following recommended range with four different stimulation types that including: 40 Hz 5 N, 40 Hz 1.5 N, 20 Hz 5 N and 20 Hz 1.5 N. Control group remain life style and has no extra training. All subjects accept following test before and after experiment: determining BMI by measuring weight (kg) and height (standing, m) using a calibrated clinical weight/height scale, muscle strength, and blood test (Creatine Kinase and LDH). The data were analyzed by two-way analysis of variance (group × time) with repeated measures to examine any changes after training and tracing time (p < .05). Based on the data analysis, some key findings are listed briefly as follows: the results from muscular strength test (dominant hand and non-dominant hand) indicated four training groups (T1~T4) were got improvement significantly, but control group did not have any change (p＜.05). There were no significant differences among each group in CK and LDH testing. The study shows that muscular strength (dominant hand and non-dominant hand) was elevated in underweight female after 12 weeks upper body vibration training, and have no negative effect in muscle damage markers (CK and LDH).
