Background and Study Aim. This study aimed to examine the differences between a range of performance parameters in -Greco-Roman and Freestyle wrestlers. The study group consisted of 60 young wrestlers, of which 30 were Greco-Roman, and 30 were freestyle. Material and Methods. The parameters analysed in the study included aerobic endurance, lower and upper extremity anaerobic power and capacity, postural sway, change of direction, sprint (5m-10m-20m-30m), and visual reaction. After calculating mean and standard deviation values with descriptive statistical methods, the conformity of all variables to normal distribution was checked with the Shapiro-Wilk Test. Differences between freestyle and Greco-Roman wrestlers were determined by t-test for independent samples. The statistical significance level was accepted as p<0.05. Results. Aerobic endurance, lower and upper extremity anaerobic power and capacity, postural sway (Right Foot Anterior-Posterior, Left Foot Total, Left Anterior-Posterior, Left Foot Medial-Lateral), change of direction, 5m and 10m sprint values, and visual reaction values of Greco-Roman and Freestyle wrestlers were found similar (p>0.05). In contrast, a significant difference (p<0.05) was seen in 20m and 30m sprints, double foot total, anterior-posterior, medial-lateral, right foot total, and right foot medial-lateral postural sway values Conclusions. Greco-Roman and freestyle wrestlers can be said to show similar performance values despite the different wrestling techniques and training methods they use.

The study aimed to investigate the effect of acutely consuming high-dose isolated 6 g of taurine 90 min before incremental treadmill-running time to exhaustion (TTE) performance on maximal oxygen uptake (VO2max), maximal heart rate (HRmax), TTE, and ratings of perceived exertion (RPE). A total of ten well-trained, competitive male endurance (biathlon) athletes participated in this study. A double-blind, randomized crossover design was used in the study and consisted of three separate testing sessions. During the second and third sessions, 90 min before the exercise protocols, participants consumed ~500 ml of a sugar-free lemonade drink with either 6 g of taurine or nothing added (placebo). The incremental treadmill-running TTE performance started at 6km·h-1, and the participants warmed up for 6 minutes at this constant speed. After a warm-up, the treadmill's speed was increased by 0.016km/h per second, and the slope of the treadmill was increased by 0.5% for each 60 seconds. Oxygen uptake (VO2) and HR were measured while the participant was running on the treadmill. RPE was measured immediately after each trial using the Borg Scale (6-20 points). As a result, the acute ingestion of 6 g of taurine 90 min before incremental treadmill-running TTE performance did not enhance TTE, HRmax, and RPE but did result in a non-significant slight change in VO2max (2%).
