Examining Lactate Changes during High Intensity Spinning® Training.

The aim of the study was to examine the changes in the acute blood lactate levels of elite taekwondo players when carrying out high-intensity interval training on Spinning ® bikes. Twenty elite-level taekwondo athletes participated in the study. The subjects were selected from athletes who had been competitors for at least six years. Their average age, height and weight values were determined to be 18.89±2.07 years, 176.8 ± 8.73 cm and 70.59 ± 12.13 kg respectively. In the present study the subjects carried out high-intensity interval training using Spinning bikes based on the Tabata protocol. The loads were applied as a total of four sets of eight repetitions with the principle of 20 seconds of load followed by 10 seconds of rest with one-minute's rest given between sets. The subjects' lactate levels were measured from their fingers using the Accutrend Lactate portable lactate analyzer with the help of the strips provided. Lactate measurements were made five times: before training (Pre), after Set 1 (1S), after Set 2 (2S), after Set 3 (3S) and once the exercise was over (Post). The heart rates (HR) of the athletes were monitored by their coaches before and during exercise. The data were analyzed using One Way ANOVA in the SPSS 22 package program. A statistically significant difference was found among the baseline lactate levels, the 1S, 2S, 3S and post lactate levels in the study (p 0.05). As a result of the study it was observed that Spinning ® training carried out using the high-intensity interval training method caused a rapid increase in acute lactic acid accumulation. In the case of performance athletes, we can say that this exercise could be part of the lactate tolerance training used to counter fatigue.
