Speed-based and Mechanical Work Considered HIIT for Football Referees

Majority of the existing studies on the high intensity training of referees are heart rate-based prescription. It is probably the most commonly measured physiological marker used to control or measure exercise intensity in the field.Indeed, speed-based intensity training is more acute than heart rate-based training on the intensity of physical work performed above v/pVO2max. This study the setting of exercise intensity reference the ending velocity of the 30-15 intermittent fitness test.

Inclusion Criteria:the female referees who register as reserve national degree and above for 2022 and 2023.Exclusion Criteria:InjuredAny reason can not complete all the required training sessions.
