long term energy system consists of ____ metabolism

T

(T/F) all 3 of these ATP-generating systems ( energy systems) can contribute at the same time

short

Sprinting for 10 sec - 2 min is ____ energy system

immediate

Sprinting for 4 - 6 sec is ____ energy system

work / time

Power = _______

force * distance

work = _____

stair, 40, vertical

____ sprinting, ___ yard dash, and ____ jump are all POWER tests

Wingate

The ______test is an all-out 30 second trial on a stationary bike used to asses anaerobic power

5, 30

In the Wingate test, the highest power output in the first ___ seconds is considered to be peak power.

“Anaerobic work,” which includes contributions of the immediate and short-term ATP generating systems, is the total work over the first ___ seconds

peak power / body mass

In Wingate test:

• Relative peak power = ________

VO2 max, 125%, 25%

Maximally-accumulated oxygen deficit test

• Before this test, subjects do a ____ test.

• Then, on another day, they do a treadmill run at a pace that is ___ % of their pace at VO2max in the previous day’s test.

• They go until they can no longer maintain the pace.

• Can calculate oxygen debt from time that they maintained ___% above VO2max pace

VO2 peak

the measure when a subject says they’ve had enough and shut it down but there’s no evidence of the plateau.

men

Which has a higher VO2 max ( liters / min), men or women?

men

Which has a higher VO2 max ( mL/ kg *min), men or women?

bigger, mass

the relative difference in VO2max between men and women is pretty large when expressed in absolute terms (Liters/min).  That’s because men are generally ___.  The values are closer together when normalized to body _____(ml per kg per min).

women

who has higher body fat, men or women?

treadmill, running

For what condition is VO2max (ml/kg/min) higher: cycling vs treadmill?

Why? ____ requires recruitment of more muscle mas

dec

Aerobic fitness tends to ___after the third decade of age

true

( T/F) aerobic training cannot prevent age-related decline

same

The slope of age-related decline of aerobic fitness is ____ for active and sedentary subjects

activity, heredity, training, sex, size,age

6 Factors influencing VO2max

submax , drops, survey

Ways to predict VO2 max

• HR during ____ exercise

• how quickly HR ___ after a step test
