Comparison of Different Forms of Recovery on the Functionality After Physical Exercise

Summary

Delayed onset muscle soreness (DOMS) and decrease of musculoskeletal function are due to high intensity training and / or sports activities. These occur due to micro lesions of muscle tissue resulting in nociceptor sensitization. Non-pharmacological interventions to attenuate DOMS and favor muscle recovery have been studied. These interventions aim to maintain performance levels, especially in competitions. Among these interventions, cryotherapy (cold water immersion) and active recovery already have good clinical evidence. Currently a new proposal has been gaining ground for myofascial self-release (foam roller), however its mechanisms and clinical evidence are not yet well established. The aim of the present research is to compare the effects of passive recovery, active recovery, cold water immersion recovery and recovery through myofascial self-release on DOMS and the functionality of healthy volunteers undergoing resistance exercise.

Foam Roller Recovery

Myofascial self-release will be developed through the foam roller (FR), where participants will use a custom-made foam roller constructed from a hollow polyvinyl chloride tube that will have an outside diameter of 10cm and a thickness of 0.5cm and will be surrounded by neoprene foam with a thickness of 1cm. Each volunteer will be shown the technique for the 5 muscle groups involved and the technique used for each muscle group. FR will consist of 45s of rolling for each muscle in the left lower extremity, 15s of rest, 45s in the lower right extremity. They will be instructed to begin with the practice on the most distal portion of the muscle. They will be instructed to place as much tolerable body mass on the FR at all times and to roll their body mass back and forth along the roller as smoothly as possible at a rate of 50 beats per minute (ie , 1 rolling motion for 1 to 2s). The total technique time is estimated at 10 to 15min (PEARCEY et al., 2015).

OTHER

Active recovery

Active recovery for 20 minutes (MIKA et al., 2016) will consist of pedaling on a stationary bike at a speed of 50 to 60 rpm. The load (49 ± 9 W) will be adjusted individually so that the heart rate is close to 100 bpm (about 50% of the theoretical maximum heart rate). This effort intensity is similar to that used in the literature (CRISAFULLI et al., 2003; FAIRCHILD et al., 2003; VANDERTHOMMED; MAKROF; DEMOULIN, 2010)

OTHER

Immersion in cold water

Immersion in cold water will consist of the individual sitting in a plastic pool with water at the water level of the umbilical scar. Water temperature is between 11 and 15ºC, for a period between 10 and 15 minutes immediately after the exercise protocol (MACHADO et al., 2016b; MCDERMOTT et al., 2009). Water temperature will be controlled by adding or removing ice. This method has been applied by studies conducted by our research group (MISSAU; SIGNORI, 2017).

OTHER

Passive recovery

Volunteers will be seated for 20 min after the resistance exercise session (TEIXEIRA et al., 2014a, 2014b).
