Brief summary

Objective: The aim of the present investigation was to determine whether using cryostimulation (partial-body cryostimulation) impacts sleep quality in professional soccer players. Different exposure durations at -180°C were tested randomly after standardized training sessions in 9 professional soccer players (no cryostimulation, 180-s exposure, two 90-s exposures separated by a 5-min rest at room temperature, and 90-s exposure), and the effects on sleep quality using 3-dimensional accelerometers worn during sleep were assessed.

Interventions

each player experienced different exposure durations at -180°C in a partial-body chamber (Cryotechno®, Castelnau le Lez, France) in a random order (no cryostimulation, 180-s exposure, twice 90-s exposure separated by a 5-min rest at room temperature, and 90-s exposure). These exposures are separated by a Week. A partial-body chamber consists of an open tank in which the subject is exposed to cold, excluding the head and neck. The cold temperature is obtained by spraying nitrogen (expanded nitrog

These exposures are separated by a Week. A partial-body chamber consists of an open tank in which the subject is exposed to cold, excluding the head and neck. The cold temperature is obtained by spraying nitrogen (expanded nitrogen) inside the tank. Such devices have already been described. In the cabin, the subjects wore bathing suits, a pair of gloves, socks, and slippers. The subjects were instructed to turn around continuously in the cabin during the exposure period. The cryostimulation sessions were undertaken under medical supervision. The exercise physiologist administrated the intervention and the mode of administration was one-on-one.
