Aging is a differentiation process with chronological, biological, psychological and social characteristics, which occurs in the intrauterine period and ends with death. With aging, the structures and functions of tissues are affected and there is a decline in overall physical performance. Asanas in yoga use tonic muscle contraction coordinated with breath control and kinesthetic awareness, which saves energy compared to phasic muscle contraction often observed in physical exercises. We have not encountered a study examining the effect of asanas on muscular activity in old age. Our study will provide support to the literature in this direction.

The study will be carried out on volunteers after the approval of the ethics committee. Before the research, individuals and / or their relatives will be informed about the purpose and content of the study. Participants will first start in mountain (Tadasana) asana. They will then be asked to come to the following asanas in a randomized order. In each of the asanas, you will statically pause for 15 seconds and repeat the movement three times. Participants will rest for 2 minutes between asanas. If deemed necessary during the application, modifications will be made in the movements and security measures will be taken. Warrior 2, elongated triangle, and Light Cluster stances will be evaluated for each limb separately. Muscle activations of individuals to the contralateral external oblique abdominal and ipsilateral adductor longus muscles of the anterior oblique myofascial chain lines and the contralateral latissimus dorsi and ipsilateral biceps femoris long head muscles to the posterior oblique myofascial chain lines will be evaluated using superficial EMG.
