Kinesiology

Purpose

learn the basis and technique involved in administering the YMCA Cycle Ergometer Test, Astrand-Ryhming and Bruce Treadmill Test for estimating Aerobic capacity/power.

Aerobic is

with oxygen

For Muscles to be supplied with increased oxygen these must occur

1) increased cardiac output
2) increased ventilation
3) a diversion of a greater proportion of the cardiac output to the active muscles.

Cardiac Output

the amount of blood pumped by the heart each minutes, is usually expressed as liters/minutes

Cardiac output =

HR x SV

Stroke Volume

the amount of blood pumped per beat of the heart

VO2Max

SV x HR x A-VO2 difference

A-VO2 difference

the difference between the amount of O2 extracted or consumed by the muscles and body(arterial minus venous blood O2 difference).

The YMCA and Astrand-Ryhming cycle test and Bruce Treadmill Test can be used as a test of___

Physical Work Capacity (PWC) or cardiorespiratory fitness and can be used to ESTIMATE maxVO2

Tests are based on the following

1) as cardiorespiratory fitness increases, heart rate at a given sub-maximal workload decreases
2) the higher cardiorespiratory fitness results in a higher max VO2

Tests used to estimate maxVO2 include:

step-bench tests, the 9 and 12-min run tests and 1 to 1.5 mile run tests.

Maximal Oxygen Uptake(VO2max) estimates in

Liters per minute (l/min) for the Astrand-Ryhming Test

Tables

Heart Rate vs Work Load.
Age Correction

YMCA Cylce Test

Can be used to predict VO2 based on the linear relationship between HR and work rate (VO2) at a heart rate over 110

YMCA Test

mustextrapolate HR-work rate relationship out to max HR

Cycle at____ RPM

50

1st Workload = _______

150 kgm = 0.5 kp

Each stage lasts ________

3 minutes

Take heart rate during the last ______

2 min of each stage

Heart rates during last 2 min of each stage should be within __ beats of each other, if not add 1 additional minute

5

Complete ____one work stage past the stage where a HR of 110 was reached

ONLY

Draw line through HRs starting at

HR>110

ml/kg/min =

(L/min x 1000)/body wt in kg

___min stages
