Calf Compression Sleeves Change Biomechanics but Not Performance and Physiological Responses in Trail Running.

The aim of this study was to determine whether calf compression sleeves (CS) affects physiological and biomechanical parameters, exercise performance, and perceived sensations of muscle fatigue, pain and soreness during prolonged (~2 h 30 min) outdoor trail running. Fourteen healthy trained males took part in a randomized, cross-over study consisting in two identical 24-km trail running sessions (each including one bout of running at constant rate on moderately flat terrain, and one period of all-out running on hilly terrain) wearing either degressive CS (23 ± 2 mmHg) or control sleeves (CON, <4 mmHg). Running time, heart rate and muscle oxygenation of the medial muscle (measured using portable near-infrared spectroscopy) were monitored continuously.

[P3S: Secured fitness trail set up in Guadeloupe, a tool to fight against physical inactivity: A device that has proved itself].

Objective: The objective is to introduce an original device already set up in Guadeloupe, the P3S: it is a secured fitness trail; it aims to raise awareness of the harmful effects of physical inactivity and to fight against physical inactivity.

Material And Methods: The P3S device was financed by the Regional Council of Guadeloupe and includes: (1) a first space to perform a warm-up and gymnastics; (2) the route to the market; (3) 8 physical activity workshops. Coaching by educators sportsmen and teachers of activity physics adapted is proposed, provided by the ARS of Guadeloupe.
