- ANSWER >8mmol/L what RPE (both 20 and 10 scale) determines that a person has reached their maximal effort? - ANSWER 20: >17 10: >7 what RER value determines that a person has reached their maximal effort? - ANSWER >1.1 why is the warm-up/initiation phase important? - ANSWER allows body to adjust to changing demands on the physiological, biomechanical, and bioenergetic systems as well as improves ROM and decreases risk of injury why are cool-downs useful? - ANSWER allows the body to return to near resting levels what does cardiorespiratory fitness entail? - ANSWER functional capabilities of the heart, blood vessels, lungs, and skeletal muscles to transport and utilize oxygen to perform physical work what is the FITT principle for cardiorespiratory exercise? - ANSWER F: at least 3 days a week (3-5) I: moderate (40-59% HRR) to vigorous (60-89% HRR) Ti: 30-60mins/day (150mins/week) of moderate or 20-60 mins of vigorous (75mins/week) or a combo of the two Ty: continuous or rhythmic manner that involves major muscle groups [Show More]
