简要总结
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.
详细描述
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.

研究组 & 干预措施
Exercise session followed passive recovery
Prior each to the exercises sessions (4), volunteers will undergo specific warm-up in each exercise adopted (a series of 15 repetitions with 40% of the maximum load obtained in the 10RM test). The exercise sessions will consist of four sets for 10RM, with an interval of one minute between sets and two minutes between exercises. The exercise sequence (extension chair, squat and leg press) will be randomized through a closed brown envelope draw. Prior to the 10RM test and data collection, standardized instructions regarding the experimental procedure and exercise technique will be provided. Verbal stimuli to the volunteer will be performed during the evaluations and exercises (TEIXEIRA et al., 2014a, 2014b). The interval between each exercise session will be one week. Volunteers will not perform any form of recovery for 20 min after resistance exercise session (TEIXEIRA et al., 2014a, 2014b).

结局指标
主要结局
Isometric peak torque
时间窗: 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.
