| Expected Outcome 1: Using blood biochemical assessments, post-exercise recovery (0-24 hours post-intake) is expected to be found by returning to baseline and / or by a significant difference (p less than 0.05) favorable to the main experimental treatment. (formulated milk drink [FMD]) on immune markers of systemic inflammation (interleukin 6 [IL-6], interleukin 1B [IL-1B], C-reactive protein [CRP] and tumor necrosis factor ([TNF-alpha]); immune cells (leukocytes and subclasses), oxidative stress (reduced glutathione [GSH] and oxidized glutathione [GSSH]), muscle damage (creatine kinase [CK] and myoglobin [Mb]), insulin, cortisol, hematocrit . ;Outcome found 1: Significant decrease (p less than 0.05) in favor of the main experimental treatment (formulated milk drink [FMD]) in markers of muscle damage (creatine kinase [CK] at 24 hours after ingestion; and myoglobin [Mb] at 2 hours after -inquestion); significant increase (p less thas 0.05), favorable to the main experimental treatment (formulated milk drink [FMD]), in serum insulin concentration at 2 hours after ingestion.;Expected Outcome 2: It is expected to find, using color scale and urine specific gravity scale assessments, post-exercise recovery (0-24 hours post-intake) verified by returning to baseline and/or by a significant difference (p less than 0.05) favorable to the main experimental treatment (formulated milk drink [FMD]) in the state of hydration.;Outcome found 2: All treatments provided improvement in hydration status, but without significant difference between treatments (p greater than 0.05).;Expected Outcome 3: It is expected to find, using psychometric scale assessments, post-exercise recovery (0-24 hours post-intake) verified by returning to baseline and/or by a significant difference (p less than 0.05) favorable to the main experimental treatment (formulated milk drink [FMD]) in the perception of muscle pain.;Outcome found 3: No significant difference (p less than 0.05) in the perception of muscl | — |

| Expected Outcome: Expected to be found, verified by specific physical test, post-exercise recovery (0-24 hours) checked by the return to baseline and/or through a significant difference (p less than 0.05) in favor of the main experimental treatment (formulated milk drink [FMD]) on athletic performance in neuromuscular components (jump and speed).;Outcome found: All treatments provided improvement in athletic performance in neuromuscular components (jump and speed), but without significant difference between treatments (p greater than 0.05). | — |
