Abstract Resume

Background: Post-exercise recovery is part of the physical training in athletes and represents the return of some systems to baseline, including metabolic. The Cold Water Immersion
(CWI) is presented as a recovery strategy and consists of immersing parts of the body in water with a temperature equal to or lower than 15°C. How muscle fatigue is a result of training, and one of
his markers is the concentration of lactate, is of fundamental importance viable recovery strategies for their removal. Therefore, the objective was analyze the immediately recovery after a training
and to verify the metabolic parameter about lactate from the use of immersion in cold water as recuperative technique.

Methods: A sample of 64 soccer players were randomized into two groups, control group (CG) and experimental group (EG). Participants underwent a training (50 minutes) and immediately
after the intervention performed for 15 minutes, GE received the CWI (13 ± 1 ° C) and GC stay sitting. The blood lactate concentration was measured during specific recovery times up to maximum two
hours post-training. Statistical analysis was performed using the statistical package SPSS Statistics 22.0. Initially, sphericity of the data was tested by Mauchly’s test. In case of violation of the
sphericity assumption, the Greenhouse-Geisser corrections were used. The mean and standard deviation were considered. Data were analyzed using Repeated Measure Analysis of Variance (Bonferroni’s test)
which provides information of time, group and interaction effects. Effect size (ES) was calculated using partial eta squared and interpreted as small (≥0.01), medium (≥0.06) or large (≥0.14).

Results: Both groups recovered at the same time (2 hours after exercise), the time effect 0.00 (ES: 0.752), group time effects of 0.164 (ES: 0.033) and the effect group was 0.0049
(ES: 0,075 ).

Conclusions: The recovery of the lactate behavior in blood, a metabolic variable, occurred at the same time for both groups (2 hours post-exercise), showing that CWI does not
interfere with removal of lactate post-exercise compared to passive recovery.
