Investigation of Blood Lactate Levels, Hearth Rates and Technical Performance of Hearing-Impaired Elite Male Greco-Roman Wrestlers

Abstract

This study was conducted with hearing-impaired elite greco-roman wrestlers to determine the relationships and variations in heart rates (HR), blood lactate (La) levels and number of performances during the maximal effort and recovery periods. Voluntary 8 hearing-impaired elite male wrestlers with an average age of 21,75±2,05 years participated into present experiments. Resting heart rates of the athletes were determined before the maximal effort, blood samples were taken for lactate levels, athletes took warm up and stretching exercises for 15 minutes. For maximal effort, athletes performed hip-headlock throw technique for 2 minutes in 3 periods. Proper performances were counted and heart rates were measured in between the periods. To determine recovery characteristics of the athletes after maximal effort, HR and La levels were determined at 3rd, 15th and 30th minutes after maximal effort.Heart rate responds to hip-headlock throws at the end of the 1st period were lower than the heart rates at the end of the 2nd and 3rd periods and heart rates at the end of the 2nd period were lower than the heart rates at the end of the 3rd period (p<0.05). Number of performances in the 1st period was greater than the number of performances in the 2nd and 3rd periods and number of performances in the 2nd period was greater than the number of performances in the 3rd period (p<0.05). HR values increased and number of performances decreased with the progress of periods. There were significant differences in HR and number of performances of the periods (p<0.05).HR and La reached to the maximum levels right after the end of wrestling game and a significant decrease was observed after the 3rd minute of resting (p<0.00). Significant decreases continued at the 15th and 30th minutes of the resting as compared to the 3rd minute (p<0.00). Blood lactate levels also reached to the maximum at the 3rd minute of resting with the effort spend in the 3rd period; then significant decrease was observed at the 15th minute of resting (p<0.00) and significant decreases were also observed in blood lactate levels between the 15th and 30th minutes of resting (p<0.00).It was concluded based on present findings that increasing heart rates negatively influenced number of performances. In other words, tiredness had negative effects on number of performances. Present findings also revealed that during the recovery period, lactate levels decreased quite slower than heart rates. In this sense, it was assumed that La level was the primary criterion of the recovery.
