本研究目的在探討羽球運動對青少年骨質密度之影響，以30名16-18歲身心健康正常的男性為受試者。羽球組15名、對照組15名。對受試者實施兩前臂骨（包括橈骨中、遠端1/3處、尺骨，中遠端1/3處止橈骨遠端處等三個部位）以及慣用邊股骨近端（包括股骨頸處、股骨粗隆處與沃德氏三角區等三個部位）骨質密度（bone mineral density, BMD）的測量，來探討羽球運動對青少年上、下肢BMD的影響。對照組的受試者係年齡、身高、體重與羽球實驗組相近的一般田中男生（p>.05），彼等並未接受任何運動訓練。實驗組與對照組皆未受到影響個體BMD的疾病、遺傳、服藥、攝食或行為不當因素的干擾。受試者在各受檢部位BMD以獨立樣本t-test考驗。結果發現：羽球運動對於個體上肢的橈骨中遠端1/3處與橈骨遠端處等三個部位的BMD作用明顯增進之效果(p<.05)。對於個體下肢的股骨頸處，股骨粗隆處的BMD均有顯著正面的效果。

The purpose of this study was to investigate the effect of badminton exercise on bone mineral density in the teenagers. A total of thirty regular and healthy male ranging from 16 to 18 years old was tested, which includes 15 served as badminton group and the other as the experiment group. In order to explore the influences of badminton exercise to the BMD value of upper and lower limbs in the teenager, the BMD values in the parts of two forearm bone (including parts of medium-to-distal 1/3 radius shaft, medium-to-distal 1/3 ulna shaft and distal radius shaft) and accustomed use near femur (including parts of femoral neck, trochanter and Ward’s triangle regions) were accessed for the test. The group for comparison is the male students of junior high school similar to badminton experimental group in age, body height and body weight respectively. Subjects with hereditary disease, mediation histories, daily diet and behavior malfunctions that might affect evaluation of BMD for the experimental and comparative groups were excluded. The independent t-test was applied. According to the results, it was shown the affections of badminton to the BMD value in the places of the upper limb were obvious (p<.05); whereas, effects of femoral neck and trochanter in the lower limb were positively significant.
