gait speed. 7 , 8 Poor lower limb strength has been associated with slow gait speed and the likelihood of falling, making it an important predictor of functional status in older adults. 9 – 12 The association exists because joint torques at the hip, knee, and ankle are summed in a coordinated fashion

forearm to the upper arm. Inertial properties of the throwing arm segments used for this analysis were estimated based on the method previously described. 40 For the purpose of this study, joint torques are reported as internal joint torques and only peak varus torque at the elbow of the throwing arm

Estimates of in vivo Achilles tendon (AT) force are needed to measure tendon mechanical properties as a function of the measured net ankle joint torque, and to understand AT function using musculoskeletal modeling approaches. The AT moment arm is required to convert the measured external ankle

activation or strength of the hip abductors would decrease the stiffness of the hip joint in the frontal plane. Joint torque is the product of muscle force and muscle moment arm. Therefore, decreased peak activation or strength would directly affect the capacity of a muscle to produce joint torque. 48

]: walking = 43.2% [7.4%]; standard step = 41.2% [8.5%]; high step =34.9% [7.2%] stance). Sagittal plane ankle and midfoot joint powers were calculated as the product of joint torques and relative segment to segment angular velocities (τ·ω). 12 The ankle and midfoot positive and negative total powers were

&R test. Stretching-induced changes in flexibility were associated with changes in functional performance. The details of these findings and their implications are discussed below. Static stretching improves flexibility, joint range of motion, and joint torque. 25 – 28 Older adult fallers display reduced
