Isokinetic Fatigue Index in a Population of Triathletes

The aim of this study is to evaluate the relevance of carrying out a measure of muscular fatigability by isokinetism, in the search for factors favouring micro-traumatic lesions of the lower limbs in a population of triathletes.This is a prospective monocentric pilot study of the before/after type in which the patient is his or her own control, in high-level triathletes practising an endurance sport, who have had more than 7 consecutive days off running due to a musculoskeletal injury during the previous sporting year.

Inclusion Criteria:Having had a practical running break of more than 7 consecutive days due to a musculoskeletal injury of a lower limb during the previous sport yearWilling to comply with all study proceduresHaving given written consentSocially insuredExclusion Criteria:Pain that does not allow an isokinetic test to be performedKnee joint amplitude less than 100° of flexion or flessum greater than 5°.History of rupture or ligamentoplasty of the anterior cruciate ligament less than 2 years agoHistory of knee surgery less than 2 years
