Abstract Resume

Background: Post-Exercise Recovery Is an Important Process that Increases Functional and Structural Muscle Recovery. Several Methods Have Been Tested, Including Cryotherapy and
Light-Emmiting Diodes (Led) Therapy. The Aim Of This Study Was to Analyze the Effect of Three Different Recovery Methods Post Jiu Jitsu Fight, by Examining Changes in The Variables: Heart Rate (HR),
Blood Lactate Concentrations [La], Rating of Perceived Exertion (RPE) and Handgrip Strength.
Methods: This Is an Experimental Approach Applied in a Cross Over Manner. Ten Male With Less than Two Years of Experience Performed Two Rounds of Fighting During Six Minutes Each,
with Intervals of 15 Minutes, in which the Recovery Intervention Method Was Applied and the Proposed Variables Were Assessed tn the Following Times: [La]: Before 1st Round, Just Post-1st Round, 3, 5,
And 7 Minutes Later, Post-2nd Round, 3, 5, And 7 Minutes Later; –HR: 1, 3, 6 Minutes After 1st Round, Just After Recovery Method, 1, 3, 6 Minutes After 2nd Round; Rpe: Post 1st Round And Post 2nd
Round; Handgrip Strength: Before Fights And Immediately After It. Three Different Recovery Methods Were Applied in Three Different Days with Interval of Roughly One Week: Led Therapy (Two Points Of
The Forearm, Bíceps, Tríceps – 30 Seconds Each, Equipment THOR®, São José dos Campos - Brasil); Cryotherapy (Arms Immersed in Cold Water (10-15ºC) During 10 Minutes), and Passive Recovery (Resting in
Seated Position for 15 Minutes). Data Was Presented in Mean ± Standard Deviation and Analyzed Through Two-Way ANOVA for Repeated Measures. Significance Was Set at P<0.05. Data Was Qualitatively
Analyzed Based on Effect Sizes (ES).
Results: There Was a Significant Time Effect on [La] (P<0.01) with No Effect of the Recovery Method (P=0.69). Baseline [La] Was Significant Lower than the Other Times of Analysis.
There Was No Time or Recovery Method Effect on RPE. For HR, We Observed No Effect of Time, in which It Kept Decreasing During the Recovery Period (i.e., Times 1, 3 And 6 Minutes After Each Round).
However, No Effect Was Observed for The Recovery Method. Finally, There Was No Recovery Method Effect on Handgrip Strength (p=0.45) While a Time Effect Was Observed (p<0.01). The Qualitatively
Analyses Revealed a Moderate Effect Size for Handgrip Strength After Cryotherapy (Post 1st Round: 44.8 ± 6.7 kgF Versus 48.2 ± 5.7 kgF; ES = 0.54) And LED Therapy (Post 1st Round: 45.5 ± 5.0 kgF
Versus 49.0 ± 5.8 kgF; ES = 0.64) Measured Before Starting 2nd Round.
Conclusions: We Observed No Differences Between the Recovery Methods For [La], As Well for the HR and RPE. However, We Demonstrated a Moderate ES for the Strength After Cryotherapy
and Led Therapy Compared to the Post-Round 1 Suggesting that These Recovery Methods Provide Benefits to Muscle Recovery After the Fight.
