The purpose of this study was to evaluate physiological performance parameters of the elite karate-kumite athletes via the simulated karate performance test (SKPT). Sixteen elite male karate athletes from The Turkish National Team participated in the study- (age: 23.31±4.27 years, height: 173.4±4.91cm, weight: 68.8±8.17 kg, BMI: 22.85±1.96 kg/cm2). The SKPT protocol included 5 sets of 3 minutes simulated karate competition bouts, which included randomly timed 4 karate techniques (2 hands and 2 foot) in 7 seconds. With higher level of performance, the duration of the attacks increased whereas the rest periods shortened, but the total duration of the level remained constant (3 minutes). The blood lactate concentrations, heart rate, ventilation and oxygen consumption of the athletes were evaluated pre, mid and post SKPT. Statistically significant differences were found in all recorded parameters (p

This study aimed to examine the effects of using a mouth guard in Karate on respiration parameters. The study sample consisted of 10 volunteer elite male karate athletes who participated in the National Karate Team and still practice the sport (24.4±6.3years, 176.2±7.4 cm, 71±4.1 kg). The athletes were exposed to respiration tests without and with mouth guard with 2 days interval that give FVC, FEV1, MVV and PEF values. In the light of the found parameters, were no meaningful differences were observed in measurements of parameters between the measurements with and without a mouth guard (p > 0.05). The athletes continued their routine training between pre-test and post-test. In conclusion it was seen that the use of mouth guard did not directly affect the breathing performance.

Calismaya Karate Milli Takimi’nda yer almis ve aktif spor yasantisi devam eden gonullu 10 erkek elit karate sporcusu (24,4±6,3yil, 176,2±7,4 cm, 71±4,1 kg) dahil edilmistir. Sporcular FVC, FEV 1 MVV, PEF degerlerinin elde edildigi solunum testlerine 2 gun ara ile disliksiz ve dislikli olarak katilmistir. Kaydedilen parametreler isiginda, dislikli ve disliksiz olcumler arasinda istatistiksel acidan anlamli bir iliski gozlenmemistir (p > 0.05). Sporcular on test ve son test arasi rutin antrenmanlarina devam etmistir. Sonuc olarak, dislik kullaniminin solunum performansini direkt olarak etkilemedigi gorulmustur.
