简要总结
Objectives: To analyze the behavior of the effects of massage on clinical, metabolic and functional variables in different scenarios: i) under no stress or massage application; ii) after massage; iii) after exhaustion protocol; iv) after the immediate application of post-exercise massage; v) after application of the massage 1hour post-exercise.
Method: This was a randomized cross-over clinical trial in which 24 participants had their clinical, functional and metabolic outcome data analyzed under different scenarios: i) control scenario (CO): basal condition (under no stress or massage application); ii) Massage (MA): after receiving the massage; iii) Exhaustion protocol (PE): after protocol of exhaustion; iv) PE + immediate massage (EMI): after the protocol of exhaustion followed immediately by massage; iv) PE + delayed massage (EMT): after the protocol of exhaustion and massage received 1h after its end. The exhaustion protocol used consisted of 10 series of 10 jumps and one Wingate test and the manual massage protocol was composed of 12 minutes of massage, 3 minutes for the anterior region of the thigh of each lower limb and 6 minutes to the dorsal trunk. The variables studied were: muscle soreness, perceived recovery, maximal voluntary isometric contraction (MVIC), strength and power in the guided bar, vertical jump and blood lactate concentration [Lac].
Measurements. The primary outcome measures will be measured 2h after the start of each stage, and the secondary outcome measures will be measured at specific times during each stage. The primary outcome includes measures of functional performance, and the measures of secondary outcome includes clinical and metabolic variables.
详细描述
Introduction: Background: Massage has been shown over the years a recuperative technique widely used in sports. Studies demonstrate divergent results of the technique in terms of recovery of functional, clinical and metabolic performance after exercise. The wide methodological variety of these studies, as in relation to the moment of massage application, may be a possible justification for such a scenario. Thus, the study investigating the effects of massage applied at different moments of post-exercise recovery deserves to be highlighted.
Objectives: To analyze the behavior of the effects of massage on clinical, metabolic and functional variables in different scenarios: i) under no stress or massage application; ii) after massage; iii) after exhaustion protocol; iv) after the immediate application of post-exercise massage; v) after application of the massage 1hour post-exercise.

Exhaustion protocol: consisted of 10 series of 10 jumps and one Wingate test. Manual massage protocol: was composed of 12 minutes of massage, 3 minutes for the anterior region of the thigh of each lower limb and 6 minutes to the dorsal trunk.
Measurements. The primary outcome measures will be measured 2h after the start of each stage, and the secondary outcome measures will be measured at specific times during each stage. The primary measures includes the Strength and power test, Maximal voluntary isometric contraction (MVIC) and Squat jump. The secondary measures includes the subjective pain assessment, perception of recovery, psychological questionnaire, belief questionnaire and de analysis blood lactate concentration.

研究组 & 干预措施
S1 (Basal)
The behavior of the variables of functional and clinical outcome will be analyzed under no stress or recovery technique. In this stage, only the functional tests and the collection of clinical data will be performed.
S2 (Massage)
The behavior of the variables of functional and clinical outcome will be analyzed under stress or recovery technique. In this stage, only the functional tests and the collection of clinical data will be performed.
干预措施: Massage Protocol (Other)
S3 (Exercise)
The behavior of the variables of functional, clinical and metabolic outcome will be analyzed before the exercise protocol is performed. In this stage the volunteers will first perform the protocol for exhaustion, and in specific moments the blood lactate and clinical data will be collected, and 2h after the beginning of the exercise protocol, the functional tests will be performed.
干预措施: Stress Protocol (Other)
S4 (Exercise + Immediate Massage)
In this stage, the behavior of the variables of functional, clinical and metabolic outcome will be analyzed from the exercise protocol, followed by massage. Firstly the volunteers will carry out the protocol for exhaustion and the massage application will be done immediately after the end of the exercise. Blood lactate and clinical data will be collected at specific times during this stage. After 2h of the beginning of the stress protocol, the functional tests will be performed.

• S5 (Exercise + Active Recovery + Delayed Massage)
In this stage, the behavior of the variables of functional, clinical and metabolic outcome will be analyzed before the exhaustion protocol and the application of the massage after 1h of passive recovery. Firstly the volunteers will perform the protocol for exercise, followed by a passive recovery of 1h and then the massage application. The functional tests will be performed 2 hours after the stress protocol begins. Again, blood lactate collection and clinical data will occur at specific times.

结局指标
主要结局
Strength test
时间窗: In Stage 1 (Baseline), 2 hours after the intervention in Stage 2, and 2 hours after the stress protocol in Stages 3, 4 and 5.
In a vertical squat with a guided bar, the participants performed squats with continuous movement until the thighs reached the horizontal plane, with the trunk as aligned as possible, and immediately performed the opposite movement, returning to the initial position. For the strength test, the heating was composed of 10 repetitions at 40% of the body mass of the participants. The last trunk extension performed without compensations with the highest possible load was determined as 1RM (one-repetition maximum). There were 2 minutes of rest between sets.
Power test
时间窗: In Stage 1 (Baseline), 2 hours after the intervention in Stage 2, and 2 hours after the stress protocol in Stages 3, 4 and 5.
In a vertical squat with a guided bar, the participants performed squats with continuous movement until the thighs reached the horizontal plane, with the trunk as aligned as possible, and immediately performed the opposite movement, returning to the initial position. The distance performed eccentrically and the concentric velocity of each repetition were recorded by a linear velocity transducer. The eccentric phase was performed at a controlled mean velocity of 0.5 m/s and the concentric phase at maximum velocity (explosively). The warm up was composed of five repetitions with the bar (14 kg) and the test was performed progressively and with increments of 10 kg in each series, with two attempts performed with each load until the participant reached the load closest to his 1RM. There was a 2-minute interval between repetitions. The best attempt with each load was recorded.
Squat jump
时间窗: In Stage 1 (Baseline), 2 hours after the intervention in Stage 2, and 2 hours after the stress protocol in Stages 3, 4 and 5.
For the initial positioning of the test, the participant was instructed to remain with the soles of the feet in contact with the jump platform (Multisprint, Hidrofit, Brazil), lower limbs flexed at 90º, hands at waist, trunk erect and without previous movements. Participants were familiarized with the test procedures, and were instructed to perform a maximum jump keeping the knees extended (180º of angulation)(27). Each participant performed three jumps with rest interval of 30 seconds between them and the best measure was adopted.
Maximal voluntary isometric contraction (MVIC)
时间窗: In Stage 1 (Baseline), 2 hours after the intervention in Stage 2, and 2 hours after the stress protocol in Stages 3, 4 and 5.
Prior to the MVIC assessment, the participants performed a warm-up consisting of 10 repetitions of knee flexion-extension at 180°.s-1 (3.14rad.s-1) throughout all the range of motion(28). Muscle function was determined by the highest torque normalized by participants' body weight (MVIC/weight), obtained through MVIC of the knee extensors of the dominant limb positioned at 60º of knee flexion (with 0º corresponding to the maximum extension) in the isokinetic dynamometer (Biodex System 4 Pro, New York, USA). Participants were instructed and verbally encouraged to perform maximal contractions during the test. There were 2 minutes of rest between the repetitions.
