Athlete health and sport performance research for athletes with disabilities has increased substantially over the years as the level of competition and intensity in Paralympic sport has grown. However, relative to able-bodied sport, there remains some key areas of parasport research which are distinctly lacking. Athlete recovery, as a counterbalanc...
Presentation
Full-text available
Background: Current evidence of injuries experienced by varsity athletes is limited to reporting the specific injury type within a specific sex or within a specific sport and is largely from American collegiate sport. This limits any clear understanding of how the female athlete injury profile differs from male athletes. Furthermore, despite increa...

Background The Pilates method has become a popular exercise modality. However, there is little information on the energy expenditure (EE) and aerobic metabolism involved in a Pilates session. This study aimed to compare the EE of three different types of Pilates sessions.Methods Thirty-three sedentary women (22.03 ± 3.32 years old) performed three...
Article
Background Pilates is a form of exercise commonly used in rehabilitation settings that improves muscular fitness and flexibility. However, it is unknown whether the energy expenditure (EE) from Pilates sessions could also lead to the intensity suggested by health organizations to improve physical fitness. This study aimed to quantify and compare th...

Hypoxia with exercise is commonly used to enhance physiological adaptation in athletes, but may prolong recovery between training bouts. To investigate this, heart rate variability (HRV), systemic immune response, and response to an orthostatic challenge were measured following exercise in hypoxia and air. Eleven trained men performed a 10-km cycli...

INTRODUCTION It was quite pleasing to see the discourse that was generated on the topic of pacing. It is an important topic that does not receive a lot of attention in the empirical literature. It was remarkable that Peter Thompson's skill analysis of elite running included four elements, the latter two being perceptual-motor and cognitive in natur...

Near infrared spectroscopy (NIRS) is used to assess muscle oxygenation (MO) within skeletal muscle at rest and during aerobic exercise. Previous investigations have used a single probe placement to measure MO during various forms of exercise. However, regional MO differences have been shown to exist within the same muscle which suggests that differ...
