Q

What is the effect of resistance training on energy expidenture?

A

Increases total energy expidentur (TEE)

17
Q

Direct Calorimetry measures what?

A

Resting Energy Expidenture (REE)

a subjects heat production via change in water temp in chamber

18
Q

What is anaerobic threshold?

A

The highest oxygen uptake attained without sustained increase in blood lactate

19
Q

When does anaerobic threshold occur?

A

when O2 required by muscles cannot be totally supported by O2 delivery system.

20
Q

What feeds the energy demands during anaerobic threshold?

A

supplemented by Anaerobic glycolysis and lactate production.

21
Q

Anaerobic threshold is correlated closely with

A

VO2 threshold.

VCO2>VO2

22
Q

Subjective vs. objective test example

A

MMT, 40, plyos

vs. MMT with dynamometry
and isokinetic dynamometry
