Brief 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.

Detailed Description

The volunteers included in the study will perform an evaluation to verify the eligibility criteria, physical evaluation (weight, height, systemic blood pressure) and functional capacity to determine the exercise parameters. After will be presented to the four interventions, ie the recovery techniques after the exercises favoring their adaptation. There will be four resistance exercise sessions followed by interventions with a one week interval between each session. Interventions (passive recovery = 1, active recovery = 2, recovery with IAF = 3 and recovery with myofascial self-release = 4) will be randomized. Functionality assessments will be performed before and one hour after the intervention protocol. DOMS will be evaluated 24 and 72 hours after the exercise protocol. Evaluators will be blind to interventions.

Primary Outcome Measures

Name	Time	Method
Isometric peak torque	30 minutes after the interventions	Isometric peak torque will be measured by a load cell of a tensile-compression dynamometer (EMGSystem, São José dos Campos, Brazil), with a capacity of 500 Kgf and a resolution of 0.1 kg, a set of fixing cables, a A/D converter board (EMGSystem, São José dos Campos, Brazil), connected to a computer and analyzed by the software EMGSystem Lab V1.2_ 2010. For each muscle group, a minimum of 4 and a maximum of 10 measurements of each movement will be performed. This variation in the number of measurements is so that the last measurement is not the highest value during the test and so that the three highest values differ by less than 5%. For analysis will be considered the highest value (NELLESSEN et al., 2015). During the evaluations, standardized and vigorous verbal encouragement will be performed during the maneuver, with the aim of stimulating the individual to exert maximum effort during the entire muscle contraction time.Data will be presented in kgf.

Secondary Outcome Measures

Name	Time	Method
Delayed onset muscle soreness	DOMS will be evaluated 24, 48 and 72 hours after the exercise protocol.	Delayed onset muscle soreness (DOMS) will be evaluated by visual analog scale (EVA). The scale ranges from 0 (no pain) to 10 (maximum bearable pain).
Subjective exertion perception	30 minutes after the interventions	Subjective exertion perception ny the Borg scale (FOSTER et al. 2001). The scale ranges from 0 (no pain) to 10 (maximum bearable pain). Data will be presented in points average.
Flexibility	30 minutes after the interventions	The flexibility will be assessed by the Bank of Wells and Dilon (SIGNORI et al., 2008) and Lunge Test (CHISHOLM et al. 2012). Data will be presented in centimeter (cm).
Muscle endurance	30 minutes after the interventions	Muscle fatigue strength will be assessed by the sit-up test (TVETER et al., 2014). Data will be presented by the number of repetitions.
Muscle power	30 minutes after the interventions	Muscle power will be assessed by single-limb general function (Single Hop Test) (BOLGLA; KESKULA, 1997). Data will be presented in centimeter (cm).
Agility	30 minutes after the interventions	Agility will be assessed by t-test (LATORRE ROMÁN ; VILLAR MACIAS; GARCÍA PINILLOS, 2017). Data will be presented in seconds (s)
Speed	30 minutes after the interventions	Speed will be evaluated by 30-meter test (PEARCEY et al., 2015). Data will be presented in seconds (s).
Systemic blood pressure	60 minutes after the interventions	Blood pressure (BP) monitoring (Systolic blood pressure - SBP, Diastolic Blood Pressure - DBP and Mean Blood Pressure - MBP) will be performed using a multiparametric monitor (Dixtal, model 2021, Manaus, Brazil). The cuff will be positioned on the right arm with the patient positioned in the supine position on the stretcher. Data will be presented in mmHg.
Heart rate variability	60 minutes after the interventions	Heart rate variability (HRV) will be assessed before exercise and after interventions. The autonomic balance will be evaluated by the HRV, for the acquisition of the signal will be used a Polar frequency pulse model 810i (GAMELIN; BERTHOTOIN; BOSQUET, 2016). The acquisition of the electromyographic signal (ECG sampling rate - 1 kHz) of the RR interval time series will be acquired by continuous interval and will occur before and immediately after the interventions. For data collection the volunteer will remain lying supine at rest for 10 minutes and after standing for the same period of time, after the procedure will be repeated with breath control (16 movements per minute; I / E: 2 / 3) (NARDI et al., 2017). The analysis will be done by spectral power density (European Society of Cardiology \& The North American Society of Pacing and Electrophysiology, 1996). Data will be presented absolute units (ms2) and your normalized units (n.u.).
