Following the standing calibration trial, subjects performed double-leg drop landings from a 31-cm high box

Also, 5% to 6% of adult sports injuries occur at the hip and pelvis. 9 – 11 It is important for allied health and fitness professionals to be able to recognize common hip musculoskeletal conditions and how they can affect movements, such as the squat. Of interest are the effects of common hip

self-paced treadmill surrounded by a 180° projection screen allows an individual to be immersed in an activity or scene. A self-paced treadmill speed algorithm ( Sloot, van der Krogt, & Harlaar, 2014 ) incorporating anterior–posterior pelvis position relative to the center of the treadmill to control

filtered using a fourth order Butterworth filter with a 6 Hz cut-off, and a 7 segment (pelvis, thighs, shanks and feet) model was constructed. The pelvis segment’s center of mass (COM) position was established 6 and then COM velocity was calculated as the first derivative of COM position. Walking

clusters were used to track the thigh, shank, and foot segments during the movement trials. The pelvis was tracked by the markers placed on the posterior superior iliac spines and on the iliac crests. With the markers in place, a standing calibration trial was captured. The 3-dimensional positions of the

As regards throwing, two parameters were directly and inversely associated with perceived competence, respectively: range of motion of yaw calculated during the cocking phase (ROM Yaw ) and the maximum pelvis vertical

The movement practice of a rider on horseback is associated with greater improvements in muscle strength 8 and activation, 9 and also perceived mental and emotional status. 10 However, the effects of horseback riding exercise are

task trials, particularly the position of the trunk and pelvis. During a DVJ, the body’s COM is relatively confined in the frontal plane considering the large base of support during a double-leg landing task. This is in contrast to a small, single-limb base of support during an SLL task, which would
