The nine short months of pregnancy are associated with profound physiological adaptations to the cardiovascular and nervous systems. This includes a 50% increase in blood volume, 30% increase in cardiac output and 20% increase in heart rate at rest.
When activated by stressors such as exercise, sympathetic nerves supplying the heart and muscle blood vessels release a chemical called noradrenaline which causes increases in heart rate and blood vessel constriction.
The optimization of explosive performance is important for enhancing athletic performance and for everyday life, such as recovering from a slip, fall or trip. Explosive performance can be quantified by rate of force development, which is how fast force is produced over a given period of time.
The use of heat exposure has been a growing area of scientific interest with performance and health benefits reported for adults. Athletes typically undertake exercise in the heat to develop adaptations that lead to improved performance.
The Canadian Society for Exercise Physiology (CSEP) recommends that older adults (≥65 years) accumulate 150 minutes of moderate- to vigorous-intensity aerobic physical activity per week. Unfortunately, only ~12% of older adults in Canada achieve this recommendation and most spend ~70-80% of their waking hours engaged in sedentary behaviours like sitting
Walking is a rhythmic motor output that can be performed with little to no conscious effort. Despite seeming like a fairly simple task, walking is actually quite complex with numerous muscles, limbs and joints that must be controlled with precise timing and coordination in order to produce this activity
Evidence for the opposite limb (i.e. contralateral) effect of single limb training has existed for well over a century. This inter-limb transfer effect is commonly described as cross-education whereby single limb strength or skill training leads to an enhancement in the opposite untrained limb
In this study, we aimed to translate the finding demonstrated by research studies in rodents that performing a single treadmill session 24 hours prior to receipt of a class of chemotherapy agents called anthracyclines can protect the heart from the chemotherapy's damaging effects.
Fluid balance is important for optimal physiological functioning, health, and exercise performance. Typically, during exercise in temperatures less than 25oC, team-sport athletes have been found to lose between 1 and 1.5% of pre-exercise body mass.
Circuit resistance exercise has become an increasingly popular method for training and generally involves the use of high-intensity intervals with minimal recovery periods. Many people are adopting circuit training because high-intensity workouts require a shorter time commitment than traditional weight training or aerobic training programs.
