A comparison of EMG output of four lower extremity muscles during selected yoga postures.

The purpose of this study was to use surface electromyography (EMG) analysis to examine the muscle activation of the anterior tibialis (TA), gastrocnemius (GA), rectus femoris (RF) and biceps femoris (BF) muscles during several yoga poses: tree pose (Vrksashana), half moon pose (Ardha Chandrasana) and warrior III (Virabadrasana) when compared to a rest pose (mountain pose). Ten healthy females with more than 3 months of continuous yoga experience who practiced at least 1.5 h per week were recruited.

The effects of a therapeutic yoga program on postural control, mobility, and gait speed in community-dwelling older adults.

Objective: To examine the effects of a 12-week therapeutic yoga program on gait speed, postural control, and mobility in community-dwelling older adults.

Design: Quasi-experimental study with a pretest/post-test design. Researchers evaluated changes over time (pretest to post-test) in all outcome measures.
