Effects of Intermittent Pneumatic Compression Following Exercise-induced Muscle Damaged (IPC4sports)

This study aims to assess the recovery kinetics following an exercise-induced muscle damage activity (using flywheel) on active healthy university students.

The main questions are:

- Is intermittent pneumatic compression superior to a placebo recovering from EIMD? Participants will perform a fatiguing protocol using flywheel and recover with either intermittent pneumatic compression or with a placebo treatment (micro-current treatment, but the device turned off). They will perform several performance tests before, following the recovery period, and at the 24h and 48h following the intervention

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: IPC; a 30 min high-pressure IPC protocol	Other: intermittent pneumatic compression protocol; A 30 min IPC protocol at about 200mmHg
Placebo Comparator: placebo; A 30 min placebo	Other: Placebo treatment; The electrodes of an electrostimulation device (SP 4.0, Compex, Guildford, United Kingdom) will be positioned on participants' quadriceps. Participants will be informed that they are engaging an innovative microcurrent treatment. This procedure will last for 30 min.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Maximal voluntary contraction (knee extension)	Measures of isometric strength	10 minutes before the fatigue protocol, following the recovery protocol (30 minutes post), 24 hours and 48 hours post intervention
Countermovement jump	Jump height	10 minutes before the fatigue protocol, following the recovery protocol (30 minutes post), 24 hours and 48 hours post intervention
Broad Jump	Horizontal jump	10 minutes before the fatigue protocol, following the recovery protocol (30 minutes post), 24 hours and 48 hours post intervention
Soreness scale	Likert scale of muscle soreness - the scale ranges from from 0 (a complete absence of soreness) to 6 (a severe pain that limits the ability to move)	10 minutes before the fatigue protocol, following the recovery protocol (30 minutes post), 24 hours and 48 hours post intervention
