本研究目的旨在探討4週複合式訓練對優秀橄欖球選手最大肌力表現影響，並比較橄欖球前鋒與後衛最大肌力表現的差異情形。本研究募集中華臺北7人制橄欖球代表隊男性選手16名（22.13±1.86歲）為研究對象，依位置分成前鋒組及後衛組（各8人）。複合式訓練結合增強式訓練與重量訓練，其計畫為期4週，每週訓練2次，每次60分鐘進行3組，每組5個動作各執行12次，重量訓練強度介於70－80%一次反覆最大重量（one-repetition maximum, l-RM）。本研究於第0週及4週進行問卷調查、體位測量及各項動作l-RM測驗。結果顯示：訓練前前鋒組之蹲舉（160.63±26.25 vs. 136.88±11.93 kg）、胘二頭肌捲舉（64.38±4.17vs.57.50±3.78 kg）及硬舉（158.13±22.35 vs. 132.50±12.8 kg）的最大肌力表現顯著高於後衛組（p < .05），訓練後前鋒組之仰臥推舉（ 133.75±12.46 vs. 117.50±14.14 kg）、胘二頭肌捲舉（68.13±4.58 vs. 60.63±5.63 kg）、肩上推舉（90.00±6.55 vs. 79.38±11.48 kg）及硬舉（171.88±16.68 vs. 146.25±13.02 kg）顯著高於後衛組（p < .05）。經過4週複合式訓練，二組受試者仰臥推舉、蹲舉、肱二頭肌捲舉、肩上推舉及硬舉之最大肌力表現均有顯著進步（p< .05），前鋒組分別進步7.4%、4.7%、5.9%、17.6%及9.4%；後衛組則分別進步4.5%、7.7%、5.3%、11.6%及10.7%。本研究之結論，短期複合式訓練對優秀橄欖球選手最大肌力表現有明顯進步，尤其對上肢肌力提升的訓練效果更佳。

The purpose of this study was to investigate the effects of a short-term complex training program on maximum muscular strength performance in elite rugby players. Sixteen male athletes were recruited from the Chinese Taipei national rugby union team (22.13±1.86 years [mean±SD]) in the study. All subjects were divided by two groups: forward group (n = 8) and back group (n = 8). All subjects completed 60 minutes per day, 2 days a week at 70% of one-repetition maximum (1-RM) for 3 sets (12 repetitions) during weeks 1-2, and 80% of l-RM during weeks 3-4. Measurements of demographical variables, anthropometric indices, and muscular strength (bench press, back squat, biceps curl, shoulder press, and dead lift) were obtained at baseline and after 4 weeks. Measurements were analyzed by independent sample t-test and paired samples t-test in statistics. Results showed that the forward group in maximum strength performance of squat (160.63±26.25 vs. 136.88±11.93 kg), biceps curl (64.38±4.17 vs. 57.50±3.78 kg), and dead lift (158.13±22.35 vs. 132.50±12.8 kg) was significantly higher than the back group at baseline, respectively (p < .05). In addition, the forward group in maximum strength performance of bench press (133.75±12.46 vs. 117.50±14.14 kg), biceps curl (68.13±4.58 vs. 60.63±5.63 kg), shoulder press (90.00±6.55 vs. 79.38±11.48 kg), and dead lift (171.88±16.68 vs. 146.25±13.02 kg) was significantly higher than the back group after 4 weeks complex training, respectively (p < .05). Based on results, both of groups in maximum strength performance of bench press, squat, biceps curl, shoulder press, and dead lift was significantly improved after 4 weeks complex training, respectively (p<.05). The increasing rate in the forward group was 7.4 %, 4.7%, 5.9%, 17.6%, and 9.4%, respectively. The increasing rate in back group was 4.5%; 7.7%, 5.3%, 11.6%, and 10.7%, respectively. In conclusion, we suggested that a short-term complex training program plays an important role in improving maximal strength performance in elite rugby players, in particular, to enhance the effect of the upper limb maximum muscle strength better.
