Our latest research has just been published in the Journal of Sports Sciences!
We studied the rotational mechanics of the standing discus throw—without even holding or throwing a discus—right here in our tiny lab.

We posted a preprint titled “Mechanisms of Body Rotation in the Discus Throw: Contributions of Ground Reaction Forces and the Free Moment to the Angular Momentum of the Body–Discus System” on SportRxiv.

There are different perspectives on MDPI journals. We have shared the review reports for reference. Please consider the value of the paper after reviewing both the paper and the review reports.

Exciting news! Our latest paper is now out in Biomechanics @Biomech_MDPI, exploring a crucial topic for sprint hurdles: the impact of take-off distance. 🏃‍♀️🛑 #Biomechanics #SprintHurdles #Research @MDPIOpenAccess https://t.co/QECxTQ3XTG #mdpibiomechanics

今日は筑波大学さんにお邪魔して研究のお手伝いをしてきました。
久しぶりの動作解析。
あとフォースプレートも使ってます。

どんなデータが出るのでしょうか…。

@KeitaroSeki demonstrates that to achieve greater external work during sledge jumping, producing more mechanical energy at the proximal joint and transferring it to the distal joint could be an effective strategy for improving mechanical efficiency.
