cardiorespiratory fitness

5 essential components of physical fitness

cardiorespiratory endurance, muscular strength and endurance, flexibility, body composition

the ability to sustain vigorous activity

Cardiorespiratory endurance

Participation in many physical activity demands sustained

physical exertion

Endurance level/efficiency is related to the health of systems

cardiac, vascular, respiratory

_ has the greatest implications for lifelong health

cardiorespiratory endurance

Most research indicated that children’s physical fitness is

declining

Andersen test is for

cardiorespiratory endurance in children

sprint intervals, adds up total distance at the end of the test

Andersen test

short bursts of intense exercise, brief intense activity

Anaerobic activity

longer periods of submaximal work, long, moderate, low intensity

Aerobic activity

maximal power exerted during very short-duration, high-intensity work, how well someone’s body can meet a demand

Anaerobic power

highest anaerobic power during a bout of exercise

Peak power

average anaerobic power output for a test

Mean power

maximal amount of ATP resynthesized via anaerobic metabolism

Anaerobic capacity

Tests for anaerobic performance

quebec test, wingate test

Anaerobic performance at any age is related to

body size, metabolic ability, mobilization of oxygen delivery

Why children have less anaerobic power than adults

less muscle mass, smaller energy reserve

Improvement of anaerobic performance across age

energy reserves, improvement of metabolic processes byproduct tolerance

Total work output plateaus in _

females

contributes to improved performance of anaerobic activities

improved muscular coordination

_______ children have better anaerobic performance

mature

With training, children of both sexes have higher _

peak and mean anaerobic power

When training stops, _________ decreases

peak and mean anaerobic power

Differences in trained youth depends on _

length of training, similarity to testing, increased muscle mass, neurological adaptations

Once adult body size is reached, anaerobic performance becomes

stable

Any improvement in anaerobic development as an adult it due to , not __

training, size

Anaerobic capacity sharply declines at age ___

70

Anaerobic capacity declines beginning at age ___

35

Anaerobic performance as an adult is related to

muscle mass, fiber type, sex, and training

Women’s anaerobic development declines faster due to

muscle atrophy and hormonal changes

resistannce training has been shown to be valuable in increasing/maintaining _________ fitness in older adults

anaerobic

physiological responses to prolonged exercise

Aerobic performance

Physiology during prolonged activity

oxidative breakdown of food, depletion of local energy reserved, increased heart and respiratory rates and cardiac output and oxygen uptake

the rate at which long-term oxygen demand is met during prolonged activity

Aerobic power

the body’s total ability to use oxygen efficiency during physical activity

Aerobic capacity

the highest rate of oxygen consumption an individual is capable of during maximum physical effort

Peak VO2

oxygen

Peak VO2 reflects the body's ability to transport and use

Peak VO@ is strongly related to

lean body mass

VO2increases ____ throughout childhood

linearly

Why adults can exercise longer than children

increased heart size, hemoglobin concentration, decreased oxygen extraction

Ability to sustain exercise is relation to

body size and maturity status

Important considerations for training in children

growth status, maturation level, sufficient intensity

Prolonged training can reduce the decline in _ that accompanies aging

peak O2

Youth sport participation predicts adult ____

activity levels
