Outline of Final Research Achievements

In the realm of long-distance running training, various types of workouts are involved, such as high mileage and high-speed training. However, the specific effects of these training methods on the bones remain unclear. Therefore, this study aimed to determine the impact of different long-distance running training modalities on bone health.
The results of this study revealed that an increase in the weekly running mileage resulted in significant muscular damage and bone resorption suppression. Conversely, engaging in high-speed training during long-distance running exhibited a bone formation-dominant metabolic profile. Overall, these findings shed light on the effects of distinct training modalities on bone health and contribute to our understanding of long-distance running training strategies.

Academic Significance and Societal Importance of the Research Achievements

これまで明らかにされていなかった長距離選手のトレーニングの質と量が骨に及ぼす影響を明らかにした最初の研究となる。骨の状態やGPS搭載のスマートウォッチを用いて走行距離や走速度を定量化したことから、トレーニングの骨への影響を正確に把握できることを示した。得られた結果は、長距離選手のトレーニング計画立案の一助になると考える。
