Registration Number

Lead Sponsor
University of Trieste
Brief Summary

Cold water immersion (CWI) and percussive massage therapy (PMT) are commonly used re-covery techniques in team sports. In particular, despite its wide use, PMT has been scarcely investigated in the literature, especially regarding neuromuscular measures and in comparison with other techniques. This study aims to evaluate and compare the acute and short-term ef-fects (24 h) of CWI and PMT on muscle strength, contractile properties, and soreness after exercise. A randomized crossover study will be performed on sixteen male soccer players (22 y, 20-27) who participate in three experimental sessions involving high-intensity training and 12-min recovery including CWI (10 °C water), bilateral PMT on the anterior and posterior thigh, or passive resting. Outcomes will be assessed immediately after the exercise protocol, after the recovery intervention, and at 24 h. Isometric knee extension (IKE) and flexion (IKF), and tensiomyography (TMG) will be assessed.Muscle soreness and fatigue will be scored from 0 to 10.

Detailed Description

Participants will be invited to participate to a cross-over randomized trial, consisting in 3 experimental sessions at 7 days of distance one from another. During each experimental session, participants will be asked to train for about 45 min at a high-intensity protocol (High-Intensity Intermittent Running, plyometric jumps and isometric chair position). After the exercise, participants will be assessed for neuromuscular function (isometric strength and tensiomyography) as well as perceived soreness and fatigue. Then, in a randomized order, participants will receive three different recovery interventions: cold water immersion, percussive massage, or a passive control condition. After the recovery intervention, outcomes are assessed again, as well as at 24 h. Isometric strength is assessed with a dynamometer during knee extension and knee flexion. Tensiomyography is performed on the thigh muscles, and time to contraction and radial displacement are considered as outcomes. Soreness and fatigue are rated by the participant from 0 to 10.

Arm && Interventions
GroupInterventionDescription
PMTPercussive Massage TherapyThe PMT protocol is performed with the application of a percussive therapy gun (Theragun Elite, Therabody, USA). The participants rests with their underwear and a t-shirt on a treatment bed, and the percussive therapy gun with a "standard ball", 16 mm amplitude of percussions, and a frequency of 30 Hz, is applied to the thigh muscles of both lower limbs, 3 min on the anterior and 3 min on the posterior area of each thigh. The protocol is based on previous literature and adapted to the specific aims of this study.
CWICold Water ImmersionThe CWI protocol consists of participants standing, with only their underwear and a t-shirt, in a portable tub for cold water therapy (Qryo, Italy), with the water to their hips being constantly maintained at 10±0.5 °C by a cooling system that pumped and stirred the water inside the tub and around the participant's lower limbs. Water temperature and the duration of the immersion, which is 12 minutes for all the participants considering they were characterized by similar anthropometrics and body composition, were based on previous literature
Primary Outcome Measures
NameTimeMethod
Muscle fatigueWithin 10 minutes from exercise cessation (Post-Exercise); Within 10 minutes after the intervention (Post-Intervention); 24 hours from the exercise (Post-24 hours)

Subjective evaluation of muscle fatigue from 0 to 10 with a numeric rating scale (NRS), where 0 is no fatigue at all, and 10 is unbearable fatigue

Muscle sorenessWithin 10 minutes from exercise cessation (Post-Exercise); Within 10 minutes after the intervention (Post-Intervention); 24 hours from the exercise (Post-24 hours)

Subjective evalutation of muscle soreness from 0 to 10 with a numeric rating scale (NRS), where 0 is no soreness at all, and 10 is unbearable soreness

Secondary Outcome Measures
