線上直播階梯有氧和拳擊有氧團體課程對體適能表現及停止訓練後之影響
Effects of Online Live Step-move and Kickboxing Aerobics Group Courses on Physical Fitness Performance and Detraining in Healthy Adults
摘要
目的：本研究為比較線上直播階梯有氧之連續耐力訓練，和拳擊有氧之間歇訓練課程，於健康成人對體適能表現和停止訓練後之影響。方法：招募20位有接觸有氧團體課程經驗之健康成人，隨機分配至二組：階梯有氧組（SMA, n =10）、拳擊有氧組（KBA, n =10）。由專業有氧團課教練透過線上直播進行課程訓練，每週2次，每次60分鐘，共8週。運動介入之前（前測）、介入之後（後測）及停止訓練8週後（保留測），分別進行身體組成、體適能評估、功能性動作檢測、Y平衡測試，及跑步機進行多階段漸速跑（採血測乳酸值）。結果：顯示二組各項檢測皆後測優於前測，Cohen'd（SMA: 0.31 ～ 1.80, KBA: 0.28 ～ 1.60）。另外，後測與保留測相比，除了二組之三分鐘登階、及KBA組的Y平衡測試外，其餘各項檢測均是後測優於保留測，顯示停止訓練後影響體適能水準而導致下降。二組間各變項相比之改變量無統計差異。結論：線上直播階梯有氧和拳擊有氧課程皆有助於提升體適能之表現，及持續規律運動之重要性，可提供給相關專業人員做為線上運動指導之參考。

Purpose: This study investigated the effects of online live step aerobic and kickboxing aerobic courses on physical fitness performance among healthy adults after an 8-week period of detraining. Method: A total of 20 healthy adults who had participated in aerobic group classes were recruited and assigned to two groups: step aerobic (SMA, n = 10) and kickboxing aerobic (KBA, n = 10) groups. The courses were conducted for 8 weeks by a qualified professional instructor through online livestreaming twice a week, with each session lasting 60 min. The study assessed the participants' body composition, physical fitness, functional movement, Y-Balance test (YBT) performance, and multistage treadmill running performance on a before the exercise interventions (pretest), after the interventions (posttest), and after an 8-week period of detraining (retention test); blood samples were collected to measure lactate levels. Results: The posttest results were more favorable than the pretest results in both groups (SMA group: Cohen's d = 0.31-1.80; KBA group: Cohen's d = 0.28-1.60). Except for the 3-min step test results in both groups and the YBT results in the KBA group, all other test results were more favorable in the retention test than in the pretest, indicating that the participants' physical fitness levels decreased after detraining. No statistical difference was observed in the extent of changes between the two groups. Conclusion: Online live step and kickboxing aerobic courses can help improve physical fitness performance, underscoring the importance of regular exercise. These findings serve as valuable reference for professionals in designing online exercise courses.
