Document Summary
Adults, older adults; 150min/week: add balance if needed. 150-300min/week at >moderate intensity: increase frequency time intensity, no more than 10min/session/week. Vo2 max; maximal amount of oxygen in a large-muscle group activity that can be utilized by the cardiovascular system per unit of time at increasing intensity: average (ml/kg/min); 36-48 in women, 42-45 in men. Vo2 plateau (does not increase by 150ml/min) Submaximal testing; sedentary, injury recovering patients: assumes steady state hr has been achieved, hr-vo2 linear relationship at 110- 150bpm: not valid for those with hr altering medications. Order; resting hr and bp, posture and balance, body composition, cr assessment, muscular fitness, flexibility. Absolute (must not be done); acute cardiac events/ angina, acute systemic infection. Relative (caution); hypertension, heart disease, metabolic diseases, mental or physical impairment leading to exercise difficulties. Field tests are inexpensive predictive tests for large groups requires accurate hr measurement. Older adults require longer warm-ups, lower mets, and longer stages.
