The effect of body position, configuration, and orientation on cycling performance
… manipulation of five body positions (seat tube angle) and configurations (hip angle) on cycling performance while controlling for body orientation (trunk angle with respect to the ground). Sixteen male subjects (21-35 years of age) were tested in each of five different body positions (0, 25, 50, …

Model Free Human Pose Estimation with Application to the Classification of Abnormal Human Movement and the Detection of Hidden Loads
… of human gait to estimate an observed subject's hip angle. The hip angle is then used to calculate a normality index of the gait. The hip angle estimate and normality index are then used as inputs to a neural network. It is shown through experiment that this system provides an accurate …

A Biomechanical Analysis of Male and Female Intermediate Hurdlers and Steeplechasers
… USA Outdoor Track and Field National Championships. A 2-D analysis was performed on each subject to determine differences between events and genders for the following variables: loss of horizontal velocity, peak center of mass relative to hurdle height, horizontal position at peak center of …

A Biomechanical Analysis of Sprinters vs. Distance Runners at Equal and Maximal Speeds
… each trial was collected at 180 Hz, monitoring hip, knee, thigh, and shank positions, as well as stride length, and contact time. <strong>RESULTS:</strong> Significant differences (p < .05) between the sprint and distance groups at maximal speed were found in the following areas: speed, minimum …

Biomechanical measures of lower limb variability, and prediction of non-contact knee injuries risk factors in male athletes
… of frontal plane projection angle (FPPA) and hip adduction angle difference between legs and over season, and its relationship with injury. Methodology: After assessing the validity and reliability of FPPA and hip adduction angle during single leg squat (SLS) and single leg …

Differences in Maximal Speed Running Between Baseball Players and Sprinters
… each subject's minimum knee flexion, minimum hip angle, knee extension at toe off, contact time, stride length, center of mass at touchdown and shank angle were measured. ANOVA with repeated measures found that sprinters and baseball players display significant differences in their sprinting …

The Effects of the Environmental Design Instruction on the Students' Gymnastics Skill Refinement
… tuck jump and they were: (1) the participant's hip angle while they jumped at the highest point, (2) the participant's back point while they jumped at the highest point, and (3) the participant's jump height. Two dependent variables were measured in the experiment of mushroom circles and they …

Approaches to functional electrical stimulation induced cycling and application for the child with a spinal cord injury
… modern sensor and computing technology, two new hip-angle-based strategies (both of which utilise a limb-mounted sensor) and a “traditional” crank-angle-based strategy have been developed and incorporated into a PDA-based multi-functional FES system. Through both simulation and tricycle-based …

The Effect of Different Set-Repetition Protocols on Squat Technique In Resistance Trained Individuals
… for each repetition was recorded as well as the hip and knee angles at the bottom of each repetition. A three-way (gender x condition x time) analysis of variance with repeated measures (MANOVA) was used to analyze the data. Significance was set at p < 0.05.</p> <p><strong>Results: …

Biomechanical characteristics of multidirectional single-leg landing
… biomechanical characteristics and the relationship between different types of SLL may provide important information to help understand how individual joint biomechanics behave under different types of SLL to meet the demands of sport. Four themed studies are included in this thesis. The first …

CHILDREN’S HIPS: INNOVATION IN THE DIAGNOSIS, MONITORING AND TREATMENT OF CHILDREN’S HIP DISEASES
… an idiopathic osteonecrosis of a developmental hip that is most frequent in Northern Europe. Currently, the absence of a common set of standardized outcomes makes comparisons between studies of different interventions challenging. The overarching aim of this thesis was to understand and enhance …

Effect of workload, upper body posture, and saddle set-back on full body angular joint kinematics, muscle activity, and lower limb haemodynamics
… to assess the effects of workload, trunk and hip angle, and saddle set-back on lower limb blood flow haemodynamics. It is unclear to what extent saddle setback affects lower limb and trunk muscle activity and cycling performance, and yet the sub-disciplines of cycling use markedly different …
