AbstRACt
The purpose of this study was to determine the effects of 6-week training programme of yogic asanas on certain compo-nents of Health Related Fitness (i.e., Cardiovascular Endurance, Body Composition, Muscular Strength & Endurance and Flexi-bility). Data were collected on thirty (N=30) female subjects between the age group of 18-25 years (Mean ± SD: age 21.03 ± 1.30 years, body mass 63.40 ± 2.36 kg, height 1.62 ± 0.022 m) from Department of Physical Education (T), Guru Nanak Dev Uni-versity, Amritsar, Punjab, India. The subjects were purposively assigned into two groups: Group-A: Experimental (N1=15) and Group-B: Control (N2=15). All participants were informed about the objective and protocol of the study. The 6 week training programme of yogic asanas brought about significant improve-ment in Cardiovascular Endurance (P<.05), Body Composition (P<.05), Muscular Strength & Endurance (P<.05) and Flexibility (P<.05). It is concluded that, the 6-week training programme of yogic asanas had significant effect on Cardiovascular Endur-ance, Body Composition, Muscular Strength & Endurance and Flexibility. Thus, such yogic asanas may be recommended to improve Aerobic Fitness, Percent Body Fat, Abdominal Strength & Endurance and Trunk Flexibility.
Key Words: Health related fitness, Yogic asanas, Cardiovascular endurance, Body composition, Muscular strength & endurance and flexibility.

IntRoduCtIon
India has a rich tradition of yogic practices. Now-a-days yoga, the ancient practice of postures, breathing and meditation is gaining a lot of attention from healthcare professionals. With increasing scientific research in yoga, its therapeu-tic aspects are also being explored. The word yoga is derived from the Sanskrit root Yuj, which means to join or to yoke. In philosophical terms, yoga refers to the union of the individual self with the universal self. Yoga is one of six branches of classical Indian philosophy and has been practiced for thousands of years. Refer-ences to yoga are made throughout the vedas, ancient Indian scriptures that are among the oldest texts in existence (1). The overall performance is known to be improved by practicing yoga techniques (2) and their effects on physical func-tions were reported (3). Yoga practices can also be used as psycho-physiological stimuli to increase the secretion of melatonin which, in turn, might be responsible for perceived well-being (4). The empirical evidence accumulated over the last several decades supports the yoga-related benefits for physical health. There is also evidence that yoga practice improves muscle strength and endurance, flex-ibility and cardiopulmonary endurance (5).

Data were collected on thirty (N=30) female subjects between the age group of 18-25 years (Mean ± SD: age 21.03 ± 1.30 years, body mass 63.40 ± 2.36 kg, height 1.62 ± 0.022 m) from Department of Physical Education (T), Guru Nanak Dev University, Amritsar, Punjab, India. The subjects were purposively assigned into two groups: Group-A: Experimental (N1=15) and Group-B: Control (N2=15). All participants were informed about the objective and protocol of the study. The criterion of the subject’s inclusion was that they have an optimal physical fitness level.

The experimental group was subjected to 6-week yoga asanas consisting of daily sessions lasting 45 min each. The details of yoga asanas are shown in ta-ble 2. The following variables were recorded: Cardiovascular Endurance (YMCA 3-Minute Step Test), Body Composition (YMCA Skin fold Test), Muscular Strength & Endurance (Curl-Up Test) and Flexibility (Sit-and-Reach Test).

statistical analysis Student’s t-test for independent data was used to assess the between-group
differences and for dependent data to assess the Post-Pre differences. The level of significance was set at P<0.05.
