| Outline of Final Research Achievements |
The purpose of this study was to compare the effects of 1) different rest methods in hypoxic training (active rest [AR] vs. passive rest [PR] during an interval hypoxic training) and 2) plyometric training (PLY) in different directions (horizontal vs. vertical) on running economy (RE) at high-intensity and maximal oxygen uptake (VO2max). Five consecutive days of hypoxic training (combined sprint interval training in hypoxia and interval hypoxic training) showed no significant improvement in RE at high intensity in both groups but significant improvement in VO2max in the AR group. Both directions PLY on three times a week for four weeks showed no significant improvement in RE at high intensity and VO2max. These results suggest that improvements in RE at high intensity may be more difficult to obtain than in RE at low intensity.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では高強度REを改善させるトレーニングを明らかにできなかったが, 5日間の低酸素トレーニングによってVO2maxの改善を認めた. 専門的な長距離ランナーはすでに優れたVO2maxを有しているため, 短期間でVO2maxを改善させることは困難であると知られているが, わずか5日間で改善できることが確認された.
研究代表者はすでに5日間の低酸素トレーニングによって低強度REを改善させることを明らかにしている(研究課題:17H07403). つまり, これらの知見を組み合わせることによって, 長距離ランナーの有酸素性能力に応じた短期間の低酸素トレーニングをオーダーメイドできると考えられる.
