Modelling the respiratory control system in human subjects for excercise conditions
A model is a very helpful tool to describe, interpret and explain the behaviour of a highly complex system such as the human respiratory system. The research work presented in this thesis is concerned with the development of a nonlinear dynamic simulation model of the respiratory control system in …

Aetiology of fatigue during maximal and supramaximal exercise
… Fatigue during maximal and supramaximal excercise has traditionally been modelled from the peripheral context of an inadequate capacity to supply metabolic substrate to the contracting muscles to meet the increased energy demand.

A Pavilion for Time
… time as experienced. It is a heuristic excercise. Its goal is to encourage or rather enhance an understanding of phenomenological time. This thesis does not attempt to answer the question "What is time?" but rather, with architecture, examines the question "How do we, as cognizant human …

Eye movements and processing of semantic information in the parafovea during reading
… cognition via behavioral measures during the excercise of an everyday task. The process of reading is not limited to the directly fixated (or foveal) word but also extends to surrounding (or parafoveal) words, particularly the word to the right of the gaze position. This process may be …

Effects of muscle contractions on biceps brachii oxygenation investigated by near-infrared spectroscopy
Oxidative metabolism is the dominant source of energy for skeletal muscle. To investigate muscle oxidative metabolism, it is necessary to measure muscle oxygen (O2) consumption during exercise. Near-infrared spectroscopy (NIRS) allows for the noninvasive investigation of muscle oxidative metabolism …

Effects of physical activity and exercise on physical and mental health outcomes in female older adults with arthritis
Background: Arthritis is a chronic, degenerative disease, which affects two million older Canadians, of which the majority are older females (65+ years). With no cure, methods to improve arthritic symptoms are essential to maintain physical and mental health. Physical activity (PA) and exercise may …

Performance characteristics of elite softball players: Changes and determinants of performance related to the lower body
Study 1: Relationship between ground reaction force and ball velocity during windmill softball pitching The purpose of this research was to (1) determine the reliability of measuring ground reaction force (GRF) in multiple pitching trials and (2) investigate the relationship between ground reaction …

An investigation into the use of exercise as a medium for mental health promotion among institutionalised children
It is widely documented that institutionalised children represent a vulnerable sector of the population as they carry a high risk for the development of psychological problems. Recently, there has been a surge of interest in the use of exercise as a medium for mental health promotion. Various …

Pilot study on Nordic pole walking and individuals with cancer: effects on physical function and health-related quality of life
Individuals diagnosed with cancer experience a high symptom burden that has a significant impact on their quality of life and an individualized, community-based Nordic pole walking (NPW) program may help to alleviate this. The primary objective of this eight-week multi-centred randomized controlled …

A goal setting approach to a healthy lifestyle in adolescent females
Obesity and overweight, caused by unhealthy lifestyle behaviours such as physical inactivity and an unbalanced diet, contribute to a multitude of problems for both individuals and the community. The literature has demonstrated that risk factors that contribute to unhealthy lifestyle behaviours …

The acute effects of whole-body vibration and heavy resistance exercise on countermovement jump
Postactivation potentiation (PAP) has been recognised as an improvement in muscle-twitch force following conditioning contractile activity. The phosphorylation of myosin regulatory light chains has been identified as the principal mechanism underlying PAP. Contractile activity has been shown to …

Physical inactivity among adolescents with physical disabilities attending high schools in Kenya
Physical inactivity together with overweight and obesity has emerged as a major health risk factor for chronic disease of lifestyle as coronary heart disease, diabetes type 2, and hypertension affecting adolescents with physical disabilities in developed countries. This has contributed to the …
