Effect of the Degree of Hill Slope on Acute Downhill Running Velocity and Acceleration [Article Review]
This study by Ebben, Davies, and Clewien investigates the acute effects of varying downhill hill slopes on sprint acceleration and maximal running velocity in athletes. Forty-four male athletes performed 40-yard sprints on five different downhill slopes (2.1°, 3.3°, 4.7°, 5.8°, and 6.9°) and a flat surface. The primary aim was to determine the optimal slope for maximizing acute sprint performance, both in terms of acceleration (measured over the first 10 yards) and maximal ve
