Brief summary

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.

Design outcomes

Primary

Measure	Time frame	Description
fatigue index between the injured leg and the healthy leg	the day of inclusion	To compare the fatigue index between the injured leg and the healthy leg in high level triathletes injured in the previous season.

Secondary

Measure	Time frame	Description
difference of the fatigue index to the difference of the Croisier ratio between the injured leg and the healthy leg	the day of inclusion	Correlate the difference in the fatigue index to the difference in the Croisier ratio between the injured leg and the healthy leg.
