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 warm-up needs should be emphasised especially in subelite 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.
