Abstract:
For many individuals, pre-participation clearance using the PAR-Q and the PARmed-X has become a barrier to adopting a physically active lifestyle. An extensive project is therefore planned to reduce the number of medical referrals from the PAR-Q and to revise the PARmed-X so that it becomes more effective, user friendly, and evidence based. The entire process will likely require 3 years to complete; therefore, as an interim solution, we propose giving greater pre-participation screening responsibility to qualified university-educated fitness professionals. The highest level of professional fitness qualification in Canada is the Canadian Society for Exercise Physiology Certified Exercise Physiologist; the requirements for this certification are such that it could serve as a model allowing other countries that use the PAR-Q to develop similarly qualified university-educated fitness professionals who could also be entrusted with greater pre-participation screening responsibility.

Exercise and Muscle Performance
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
