Sažetak
AIM: The aim of this study was to determine the effects of warm-up on the blood lactate concentration and 300 meters shuttle run performance. METHODS: The research was conducted on a sample of 20 soccer players (mean±SD: age 23.1±1.45 years ; height 174.78±5.74 cm and weight 67.83±3.37 kg). All players were members of a local lower level clubs (sub-elite level). Immediately after the 300-m shuttle run test blood lactate concentration was determined for each subject. The overall result of the 300 m test (R300m) as well as the split times for all 20-m runs (R20m1-15) was analyzed accordingly. RESULTS: Warm- up significantly improved 300-m shuttle run performance and increase blood lactate concentration. The mean lactate value for the players who completed the warm-up protocol was 10.74±1.02 mmol · L-1 with a range between 9.3 to 13.0 mmol · L-1. Significantly lower (p<0.05) lactate values were found at 6.72±1.08 mmol · L-1 (range = 4.4 - 7.9 mmol · L-1) without a warm-up. CONCLUSION: Warm up increases exercise performance. Therefore, the awareness of warmup needs should be emphasised especially in sub-elite athletes. Warm-up should be an integral part of any organized activities in order to achieve better results and prevent injuries. The intensity of warm-up must be taken into account because intense warm up may negatively influence the metabolic processes.
