TL;DR: Overall, the current literature supports clearly the dose-response relationship between physical activity and the seven chronic conditions identified, and higher levels of physical activity reduce the risk for premature all-cause mortality.

TL;DR: There is strong evidence that aerobic exercise conducted 20–40 min and 3–5 days per week is beneficial for enhancing aerobic fitness, walking speed and walking endurance in people who have had mild to moderate stroke and are deemed to have low cardiovascular risk with exercise after proper screening assessments (grade A recommendation).

TL;DR: In this article, the authors seek evidence-based support for the PAR-Q and PARmed-X forms, identify whether further revisions of these instruments are warranted, to determine how people responding positively to questions on thePAR-Q can be safely cleared without medical referral, and to develop exercise clearance procedures appropriate for various clinical conditions across the human lifespan.

TL;DR: In healthy active individuals, a physical activity program of at least 30 min in duration for three sessions/per week is associated with consistent improvements in health status, including body composition and VO2max.

TL;DR: In this article, the utility and effectiveness of the existing PAR-Q and PPIQ and the PAR-PQ and PIQ-PAQ were evaluated. But, the authors indicated that there are limitations to the utility of existing PARQ and PAQ.
