Joint Motions Of The Knee, Hip, And Trunk During A Single-Leg Step-Down Test And Running, Cody J. Brocato
WWU Graduate School Collection
The purpose of this study was to examine the relationship between kinematic variables at the knee, hip, and trunk during a single-leg step-down test (SDT) and running. Twenty-five healthy subjects (12 male, 13 female) participated in the study; mean ± SD age, 32.8 ± 5.9 years; height, 173.9 ± 8.7 cm; body mass, 70.84 ± 11.3 kg; run volume, 59.5 ± 30.4 km/wk; cadence, 173.1 ± 11.5 steps/min). Dominant leg peak knee flexion was identified during the run (PKF-RUN) and used to find frontal plane knee and hip, and sagittal plane trunk angles. The same treadmill-matched knee flexion angle for …
Does Cycling Cadence Affect Interlimb Symmetry In Pedaling Power In Individuals With Parkinson's Disease?, Gary D. Wiley Jr.
Does Cycling Cadence Affect Interlimb Symmetry In Pedaling Power In Individuals With Parkinson's Disease?, Gary D. Wiley Jr.

Cycling at faster pedaling rates leads to symptomatic improvement in patients with Parkinson’s disease (PD). However, these patients show inter-limb asymmetry in pedaling power when cycling at their slow self-selected cadence. The effects of faster pedaling cadence on symmetry of effort between limbs is unknown. We compared the effect of pedaling cadence on symmetry of crank power output in individuals with PD versus healthy controls. In this case series, two participants with PD and two healthy controls performed 3-minute bouts of stationary cycling at three cadences (50, 65, 80 rpm) at 60W and self-selected workload. Power output contribution of each …

A Comparison Of The Effect Of Conditioning Activity Type On Post-Activation Potentiation, Alexander I. Grey
WWU Graduate School Collection
This study compared the effects of two conditioning exercise types on subsequent countermovement jump performance. Fifteen male collegiate rugby players (age 21.1 ± 2.3) completed two experimental protocols in a randomized order. The first protocol consisted of 3 sets of a 5 second maximal isometric half squat (ISO), with 1 minute rest intervals between sets. The second protocol consisted of 2 sets of 5 depth jumps (DJ) at a platform height which was determined by the athletes’ reactive strength index (RSI). These methods were each adapted from prior literature where post-activation potentiation (PAP) was achieved, in order to determine the …
