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 …
