Arm 1
Experimental
swimming economy
This is a study based on a comparative clinical trial (effect of an imposed V and/or SR on the swimming economy of swimmers or para-swimmers). This longitudinal study is carried out on a representative sample of swimmers and para-swimmers selected for their potential at the Paris 2024 Olympic and Paralympian Games. Following a standardized warm-up, all swimmers will perform intermittent swimming tests of progressive velocity in a 50 m indoor pool in their swimming specialty with or without an imposition of the SR to adopt. During the trials, the swimmers and para-swimmers will be equipped with inertial measurement units, as well as a heart rate monitor and tissue oximeters. The swimming and non-swimming phases will also be filmed continuously. Gas exchanges will be recorded 2 minutes after the warm-up and during the 7 minutes of passive recovery. Micro blood samples will be taken from the earlobe at the end of the warm-up and at 1, 3, 5 and 7 minutes of recovery between each trial.
