Speed-based and Mechanical Work Considered HIIT for Football Referees
Study Details
Study Description
Brief Summary
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.

Detailed Description
This study was carried out during the 10 weeks of before the seminar which conducted before the season. The assessments were carried out pre and post training intervention in the before and after week of the intervention, it includes 30-15 intermittent fitness test(VIFT),dynamic Yo-Yo intermittent recovery test, 40m repeat speed ability test, change direction test and cooper test.The experimental group(EG) take 10 weeks Speed-based (VIFT) HIIT protocol performed on each Wednesday and Saturday, 60 min for each session. One EG with mechanical work combined in the HIIT exercises, and another EG is not. The control group during the study performed on the same occasion heart rate-based HIIT.
The TL was assessed using the 0-10-point rating perceived exertion (RPE) scale according to the procedures. With the aim to obtain more detailed information especially the muscle strain, during each occasion (i.e., training session or match) the referees should provide differentiated RPE (dRPE) for respiratory (RPEres) and leg muscle (RPEmus) exertion perception.
