Purpose: This clinical study was carried out with the aim of investigate whether Hatha Yoga (HY) training affects aerobic and anaerobic power in healthy young adults. Material and method: 33 sedentary, healthy, young adult subjects, aged 18 to 26 were divided into two groups according to age, sex and activity levels. 10 female and 7 male (mean 20.06 ± 2.41 years, range 18-26 years) young adults were trained with Hatha Yoga (HYG). The aerobic exercise group (AEG) consisted of 9 female and 7 male (mean 19.75± 1.81 years, range 18-26 years) young adults who performed aerobic type strength and stretch exercises of at least 60% maximal heart rate or higher. Both training programs were given by a supervisor, one hour per day, four days per week, for six weeks. Subjects in both groups were assessed by Cooper's 12 minutes running test for cardiovascular endurance and vertical jump test for anaerobic power before and after training. Results: Aerobic and anaerobic power increased by %9.8, %5.5 following HY and by %6.6, %2.3 following aerobic training respectively. A significant increase was found in aerobic power and anaerobic power (p0.05). Although there was no substantial differences between the groups concerning cardiovascular endurance (p>0.05), anaerobic power was significantly higher (p<0.05) in the HYG. Conclusion: The results of this study suggest that HY training has positive effects on cardiovascular aerobic and anaerobic power. Therefore HY could be an exercise option for enhancing aerobic and anaerobic power in young adults
