32 weeks of yoga training
yoga classes 2 times per week for 32 weeks
Other Name: activity intervention
- peak joint moments [ Time Frame: difference from baseline to 16 wk ]These are the torques produced by the muscles during performance of the yoga poses
- peak joint moments [ Time Frame: difference from 16 wk to 32 wk ]These are the torques produced by the muscles during performance of the yoga poses
- time to stand and sit from a chair 5 times [ Time Frame: baseline, 16 and 32 weeks ]In the 5-Repetition Chair Stand Test, we record the time it takes for a participant to repeatedly stand and sit on a chair 5 times.
- number of heel-rise repetitions [ Time Frame: baseline, 16 and 32 weeks ]The Heel-Rise Test is a measure of plantar-flexion endurance. Here, we record the number of full range-of-motion, heel-rise repetitions the participants can complete before fatigue.
- Time to complete Up & Go test [ Time Frame: baseline, 16 and 32 weeks ]In the Up & Go Test, a measure of mobility, we record the number of seconds it takes to rise from a chair, walk 8 feet, return and sit in the chair.
- Number of marching steps completed within 2 minutes [ Time Frame: baseline, 16 and 32 weeks ]In the 2-Minute Step Test, a measure stepping endurance, we record the number of complete marching steps the participant can perform within a 2-minute period
- Distance participant can reach forward from a sitting position [ Time Frame: baseline, 16 and 32 weeks ]The sit and reach test measures overall sagittal-plane flexibility. The participant is asked to reach as far as possible toward their dominant limb while remaining seated.
- Distance between fingers of opposing hands as participant attempts to touch fingers while reaching posteriorly. [ Time Frame: baseline, 16 and 32 weeks ]The Back Scratch Test measures upper extremity flexibility. Here the distance between finger-tips is recorded as the participant reaches posteriorly and attempts to touch opposing hands.
- Maximum passive wrist flexion, extension, radial-deviation, and ulnar-deviation, range of motion (in degrees). [ Time Frame: baseline, 16 and 32 weeks ]These tests measure the range of motion of the wrist in the sagittal and frontal planes.
- Maximum height participant can reach while standing [ Time Frame: baseline, 16 and 32 weeks ]Here we quantify the maximum vertical height participants can reach while standing.
- Maximum distance participant can reach forward while standing [ Time Frame: baseline, 16 and 32 weeks ]THe Maximum Forward Reach test is a measure of strength and flexibility. Here we record the maximum distance the participant can reach forward while standing.
- stride length during walking [ Time Frame: baseline, 16 and 32 weeks ]Here we quantify the stride length of participants during walking at a self-selected pace.
- Maximum joint angle [ Time Frame: baseline, 16 and 32 weeks ]Here we quantify the maximum joint angles of the ankle, knee, hip, trunk, shoulder, elbow, and wrist during performance of the yoga poses.
- Sway distance of the center of pressure [ Time Frame: baseline, 16 and 32 weeks ]Here we quantify the movement of the center of pressure as participants stand as still as possible
- Electromyographic activity of muscles [ Time Frame: baseline, 16 and 32 weeks ]Here we record the electromyographic activity of the Anterior Deltoid, Triceps surae, Obliques, Rectus Abdominus, Erector Spinae, Gluteus Maximus, Lateral Hamstrings, Vastus Lateralis, Gastrocnemius, and Gluteus Medius, muscles during performance of the yoga poses.
- SF-36 score [ Time Frame: baseline and 36 weeks ]Health related quality of life and mood will be assessed with the RAND Short Form-36 (Hays, 1993). The SF-36 includes sub-scales that measure: 1) health-related limitations in physical function; 2) health-related limitations in role and in social function; 3) emotional function (including positive and negative mood states); 4) pain.
