AIM: The first aim of this study was to compare the VO2 at lactate threshold (LT) and maximum rate of fat oxidation (Fatmax) intensity in wrestlers. A secondary aim was to compare the different recovery trials in wrestlers for finding effective methods of lactate removal post-match.
METHODS: Eight wrestlers (mean±SD; age, 23.2±1 year; VO2max, 55.2±3.4 mL.min-1.kg-1) completed four recovery trials in a counter-balanced order. Maximal oxygen uptake (VO2max), Fatmax, individual anaerobic threshold (IAT), individual ventilatory threshold (IVT), and LT were determined during a graded exercise test. Different recovery methods were performed at a similar time of the day after three 2 min wrestling match. Lactate concentration was obtained at rest, and at 0, 5, 10, 15 and 20 min of post-match.
RESULTS: In wrestler, Fatmax was significantly correlated with LT (r=0.47, P<0.05) and lactate concentration (mean±SD) significantly increased during the match from (1.7±0.2 mmol.L-1) to (15.1±1.3 mmol.L-1). At 5 minute, IVT method provides greater reduce in blood lactate (79% ∆La) and in other time point (10, 15 and 20 min) Fatmax intensity provides more reduce.
CONCLUSION: Fatmax intensity is the most effective method for removal lactate concentration in wrestlers. There may be a relationship between improve in endurance capacity and training at the Fatmax intensity.
