Test and Prescription Exam #1

Ability to carry out daily tasks with alertness and vigor, without undue fatigue, and withe nough reserve to meet emergencies or enjoy leisure pursuits.

Freedom from disease, with ability to carry out tasks of daily living.
Measuring- cardio, body comp., flexibility, muscular strength/endurance.

Ability to perform well in sport.
Measuring- Aerobic Power (Vo2max), anaerobic power and capacity, body comp., flexibility, muscular strength/endurance, motor ability (speed, agility, reaction time, vision.)

Physicaly Activity Readiness QuestionnaireTells you if you should check with a doctor b4 starting exercise.

V02 max. (Maximal oxygen uptake)

Energy or oxygen cost of performing work in exercise

V02= Qc(a-v)O2 difference
Qc= Cardiac Outputa= Arterialv= venous

Qc= HR * SV
Qc= Cardiac OutputHR= Heart RateSV= Stroke Volume
MAP/TPR
MAP= Mean Arterial PressureTPR= Total Peripheral Resistance

- Length (Increased in exercise)-Viscosity (Resistance to flow. b/c of increased pressure due to posture. Standing up etc.)-Diameter (Local vasodilation vs general sympathetic vasoconstriction.)
Increase in vasodilation = decrease in TPRIncrease in vasoconstriction = increase in TPR

At rest = evidence of hypertension
exercise test= for safety. To determine onset of angina ( chest pain, tells heart not enough BF.), to ensure increase in CO with an increase in work rate.

Pros- larger values then cycle egrometercons- can fall, difficult to measure EKG
