Sled-Pull Training Protocol Increases Critical Speed In Female Collegiate Soccer Players, Andrew J. Hartz, John A. Brasher, Jenevieve L. Roper, Robert V. Musci

International Journal of Exercise Science: Conference Proceedings

Critical speed (CS) is the speed one can sustain while maintaining blood lactate, phosphocreatine, and oxygen uptake levels. “Distance capacity beyond CS” (D’) is the reserve an athlete can draw from to run faster than their CS. By increasing CS and D’, athletes can sustain a faster threshold pace (CS) and have a greater sprint capacity (D’). Unlike distance traveled and speed, which do not reflect the metabolic strain of an exercise, CS and D’ assess the relative intensity of an activity to provide individualized inter- and intra-competition insight. PURPOSE: This investigation evaluated CS and D’ among men and women …

Effect Of Treadmill Surface Stiffness On The Running Economy Benefits Of A Highly-Cushioned Racing Shoe: A Pilot Study, Zane A. Thornton, Dustin P. Joubert

International Journal of Exercise Science: Conference Proceedings

Running economy (RE) is defined as the oxygen consumption (VO₂) at a given running speed. The Nike Vaporfly line of racing shoes, which includes more compliant and resilient midsole foam and a carbon-fiber plate, have been shown to improve RE during treadmill testing. Previous research suggests that RE in general is worse on treadmills with stiffer running platforms. However, it is unclear if the magnitude of the RE benefits provided by these new shoes relative to a control shoe differ based on treadmill stiffness. Given that some treadmill platforms allow more flex or compliance, this may be an …
