Abstract:

This study was done to find out the effects of one week endurance training in high altitude (Erciyes mt. 2300 m) on some performance, respiration and blood parameters of cross - country skiers. A total of 18 (9 male, 9 fe­male) elite athletes (mean age 16,6 year) voluntarily participated into this study Some performance, respiration and blood parameters of athletes were measured four times (before altitude, 1st day in altitude, after seven days training in altitude and 1st day after altitude ) by using standardized field and laboratory tests. Statistical analysis were done by using student -1 test and Wilcoxon tests. As results of this study; although there were significant improvements in aerobic power of athletes (pO,01), im­portant improvements were not observed in anaerobic power. In addition there were no significant changes in vital capacity (VC), forced vital capacity (FVC) and first second of forced expiration volume (FEVJ at the end of one week training in altitude. Although significant improvements were observedin erythrocyte (RBC) and he-matocrite (Hct) values of athletes before and after training in altitude (p<0,05), improvements in hemoglobin (Hg) were not found significant.
