HemoNIRS: a Paradigm Shift in the Process of Musculoskeletal Rehabilitation of ACL Injuries in Cyclic Sports Athletes.

"An incremental interval test of 4\' of work for 1\' of rest will be performed at an individual intensity below the aerobic threshold. At the end of the rest minute, the load shall be increased slightly. In order to be as adjusted and individualised as possible, the subjective physical condition level stated by the patient during the sociodemographic data collection shall be taken as a reference for the establishment of the initial load, being a value of power (W) in cycle ergometer and speed (km/h) in treadmill. Never less than 50W or 6 km/h, respectively.~The minimum incremental values will be 25W or 0.5km/h until you are unable to complete a full interval. An incomplete interval shall also be recorded and analysed.~During the one minute rest period, as will have been well emphasised during the explanation of the test, no part of the body may be moved at all, so at the end of the 4 minutes of work, the evaluator will count down for the patient to get ready and remain stil"
