Purpose: The purpose of this study was to analyze the impact of match results (win-loss, score differential) on the physical performance of rugby union teams to improve training and conditioning and provide ideas for use on the playing field. Methods: Data were obtained from 45 official matches over the 2013, 2014, and 2015 seasons of one team. Global positioning system units with built-in accelerometers were worn by the players; the per-match total distances, accelerations, and impact forces were calculated for the forwards and backs. Match results consisted of two elements: win–loss result and score differential. Results: Data showed that each parameter had high values in closely fought matches when a team lost or when the point differential was small. In addition, physical performance was impacted differently from one position to another. Forwards engaged in significantly less high-acceleration and high-impact activity in wins but significantly higher activities in close matches (p < 0.05). Backs engaged in significantly higher impacts (i.e., harder/more tackles) in close matches (p < 0.05). Conclusions: Based on these data, some suggestions for new approaches that can be adopted by strength and conditioning coaches to optimize training-related performance and prevent sports injuries have been included.

肋骨の疲労骨折は,ゴルフなどで生じる中位から下位の肋骨骨折がよく知られているが,第一肋骨の疲労骨折の報告は比較的少ない。われわれは,大学生チアリーダーに発生した第一肋骨の疲労骨折を経験した。左肩甲部痛で発症し,さらに左上肢尺側のしびれと痛みを自覚した。安静および低出力パルス超音波治療によって加療するも骨癒合は得られなかったが,1年後には競技に復帰できた。X線検査では評価が困難な同部位の評価に3DCTは,有用であった。
