🚨New sprint accel paper in Journal of Sports Sciences 🚨 Congrats to @dannking98 on his first paper! We know ratio of forces (RF) is important for accel, but are there any kinematic features which relate to higher RF over the initial steps after block clearance? 🏃‍♂️🧐📉 tandfonline.com/doi/full/10.10…

Ryu Nagahara new study on 44 female and 102 male sprinters (performed 60-m sprints on force platforms). Interesting results distinguishing performance level! 🙏 pubmed.ncbi.nlm.nih.gov/37805986/ #sprintperformance
