“…It is well known, however, that VO 2 max is lower in cycling compared with a running exercise [6] and that the energy cost of running on a treadmill is not similar to running on a track [7,8]. Since this study was performed 10 years ago [5], technological progresses have made it possible to measure all the factors in field experiments by using breath-by-breath portable oxygen analyzers [8][9][10][11][12][13]. Elite athletes, who generally are not available for testing in laboratory conditions, are often more open to field tests.…”

Middle-distance running performances (800-1,500 m) relies on both aerobic and anaerobic metabolisms [1]. The relative contribution of each metabolic pathway during a middle-distance run has already been reported in elite athletes, but the performance was for males only performing on a treadmill [2]. Weyand et al. [3] have demonstrated that middle-distance performances depended more on aerobic capacity than on anaerobic capacity. Indeed, Weyand et al. [3] have shown that, in sub-elite runners (2 min 01 sϮ5 s and 2 min 32 sϮ6 s over 800 m for males and females), the peak oxygen deficit was a moderately strong predictor of middle-distance performances (38 and 27% of the variance of the performances over 800 and 1,500 m). Therefore, the energetic factors of performance were expressed with different units: the anaerobic one was reported as capacity (the "anaerobic work capacity" in J), and the aerobic one was expressed as a power (the "maximal aerobic power" in W).Wilkie's model (see method section) gives a physiological background of the hyperbolic function between the total power output (Ė r ) and the exercise duration. According to Wilkie's equation of [4], the aerobic and anaerobic factors of performance can be calculated with the same dimension because it allows the aerobic power (Ė r max aero ) to be distinguished from the Japanese Journal of Physiology, 54, 125-135, 2004 Key words: anaerobic, maximal oxygen uptake, gender, adolescence. Abstract:The aim of this study was to determine the energetic factors of middle-distance running performance in junior elite runners according to gender and by using measurements from on-track performances. Fifteen elite runners (8 males and 7 females) were investigated by means of an incremental test and an all-out run over 600 m performed with a 2-d interval.We calculated (1) the aerobic maximal power (Ė r max aero , in W kg Ė r max aero explained most of the variance in the performance (the personal best performed 8 weeks later) between genders: 65 and 79% over 800 m (T 800 ) and 1,500 m (T 1,500 ). For females, Ė r max aero explained most of the variance of T 1,500 (r 2 ϭ0.66), and Ė r max anaero improved this prediction (r 2 ϭ0.84). No energetic factor predicted the performance on 800 m run in males. In elite junior athletes, the energetic model with individual data measured over an all-out 600 m performed on a track, provides an explanation for most of the variance in middle-distance running performances between genders. The distinction between aerobic power and anaerobic power allowed an improvement in the prediction of middle-distance running performances. [The Japan-

“…Billat et al (2000) found that V max3par was not different from the maximum speed obtained in 20 m at maximal effort. However, Bosquet et al (2006) suggest that V max3par is smaller than the real V max (obtained by the average speed of the last 10 m of a maximal 40 m effort).…”

“…This statement is controversial and difficult to investigate because of the low reliability of time to exhaustion obtained in constant intensity tests (variability of tlim) (Hinckson & Hopkins, 2005). The SS equivalent to the Severe intensity domain includes performances of approximately 2 to 60 minutes (VO 2max reaching the end of the exercise) with the performance of 400 m in front crawl, the maximum aerobic speed (MAS) and CV 2par lying within that domain Lavoie et al 1983;Lavoie & Leone 1988;Rodrigues 2000;Pelayo et al 2007;Billat et al 2000;Dekerle et al 2010).…”

“…However, Costill (1994) conceptualized ADC 2par as the total work that can be performed by a set of limited power of the human body (phosphagen, anaerobic glycolysis and oxygen reserves) suggesting that the anaerobic energy system is predominant but not exclusive (Gastin 2001 (Billat et al 2000). Dekerle et al (2002) evaluated ten well-trained swimmers, when the objective was to verify the possibility of determining ADC 2par .…”

The purpose of this study was to compare oxygen uptake kinetics, ventilatory threshold of young soccer players according to playing position and to determine relationship between oxygen uptake kinetics and ventilatory threshold of young soccer players. Twenty-three young soccer players joined to study voluntarily (n=23; age: 19.8±0.4 years, body height: 179.4±7.2 cm., body mass: 74.2±7.4 kg., VO2max: 59.7±8 ml/kg/min.). The players were categorized according to playing positions. The VO2max, ventilatory threshold were determined by incremental treadmill test. Then, treadmill test at running velocity determined VO2max was performed and oxygen uptake kinetics were identified by mono-exponentinal model. The time to achieve 95% of VO2max, spending time at VO2max were accepted as oxygen uptake kinetics. The correlation among time to achieve 95% of VO2max, spending time at VO2max and ventilatory threshold values of young soccer were determined by correlation anlyze and differences according to playing positions were identified by one-way analysis of variance. It was determined significiant negative correlation between time to achieve 95% of VO2max and spending time at VO2max (r=-0.526, p<0.05). The no significiant difference among playing positions was found without time to achieve 95% of VO2max. The centerbacks had higher time to achieve 95% of VO2max values than goalkeepers (p<0.05) but no significiant difference among other playing positions was found (p>0.05). Consequently, it could be said that reaching to steady-state level early during exercise could shorten time to achieve 95% of VO2max and increase spending time at VO2max. Key Words: Oxygen uptake kinetics, soccer, play position. GENÇ FUTBOL OYUNCULARININ OKSİJEN TÜKETİMİ KİNETİKLERİNİN MEVKİLERİNE GÖRE KARŞILAŞTIRILMASI ÖzetBu çalışmanın amacı genç futbol oyuncularının oksijen tüketimi kinetikleri ile solunum eşiği değerleri arasındaki ilişkiyi belirlemek ve oyuncuların mevkilerine göre oksijen tüketimi kinetikleri ve solunum eşiği değerlerini karşılaştırmaktır. 23 genç futbol oyuncusu gönüllü olarak çalışmaya katılmıştır (n = 23, yaş: 19.8±0.4 yıl, boy uzunluğu: 179.4±7.2 cm., vücut ağırlığı: 74.2±7.4 kg., VO2max: 59.7±8 ml/kg/dk.). Maksimum oksijen tüketimi (VO2max) ve solunum eşiği değerleri, koşu bandında uygulanan ve koşu hızı giderek artan test protokolüyle belirlenmiştir. Daha sonra VO2max değerine tekabül eden koşu hızında test uygulanmıştır ve oksijen tüketim kinetiği değerleri mono-exponentinal model yardımıyla belirlenmiştir. VO2max değerinin % 95'ine ulaşılan süre ve VO2max değerinde geçirilen süre, oksijen tüketimi kinetikleri olarak kabul edilmiştir. VO2max değerinin % 95'ine ulaşılan süre, VO2max değerinde geçirilen süre ve solunum eşiği değerleri arasındaki ilişkiler korelasyon analiziyle, mevkilere göre farklılıklar ise tek yönlü varyans analiziyle belirlenmiştir. VO2max değerinin % 95'ine ulaşılan süre ile VO2max değerinde geçirilen süre arasında negatif yönlü ve anlamlı bir ilişki tespit edilmiştir (r=-0.526, p<0.05). VO2max değeri...
