Chapter 1 Flashcards
What percent of people actually exercise when measured by accelerometers
Less than 5%
Any bodily movement produced by the contraction of skeletal muscles that results in a substantial increase in caloric requirements over resting energy expenditure
Physical activity
Any type of physical activity consisting of planned structured and repetitive bodily movement done to improve and or maintain one or more components of physical fitness
Exercise
How much occupational energy expenditure has contributed to wait game
Over the last 50 years it has decreased by more than 100 cal per day there’s accounts for a significant increase in Maine US body weights for men and women
The ability to carry out daily tasks with vigor and alertness, without undue fatigue, and with ample energy to enjoy a leisure time pursuit and meet unforeseen emergencies
Physical fitness
The ability of the circulatory and respiratory system to supply oxygen during sustained physical activity
Cardiorespiratory endurance
The relative amounts of muscle; fat, bone, and other vital parts of the body
Body composition
The ability of muscles to exert force
Muscular strength
The ability of muscles to continue to perform without fatigue
Muscular endurance
The range of motion available at a joint
Flexibility
The ability to change the position of the body in space with speed and accuracy
Agility
The ability to use the senses, such as sight and hearing, together with body parts in performing tasks smoothly and accurately
Coordination
The maintenance of equilibrium while stationary or moving
Balance
The ability or rate at which one can perform work
Power
The time elapsed between stimulation and the beginning of the reaction to it
Reaction time
The ability to perform a movement within a short period of time
Speed
Are useful, convenient, and standardize method for quite to find the absolute intensity of various behaviors and activities
MET
Light physical activity
Less than 3 METs, walking slowly
Moderate physical activity
3-6 METs, 40-59% HRR, walking 3mph = 3 METs
Vigorous physical activity
Greater than 6 METs, 60-89% HRR; jogging at 5 mph = 8 METs
How does physical activity and physical fitness related diseases
Both significantly decrease your chances of CMR disease, but it is still better to be physically fit them physically active
What are the general recommendations for moderate and vigorous physical activity
All Americans should participate in an amount of energy expenditure equivalent to 150 minutes per week of moderate intensity aerobic activity and 75 minutes per week of vigorous intensity aerobic activity or a combination of both that generates energy equivalency to either regimen for substantial health benefits
What risks associated with vigorous exercise and fitness status of the individual
The risks of various cardiac events include acute myocardial infarction, ventricular fibrillation, hospitalization, and death
What are the sudden cardiac death rates
1 per 133,000 men
1 per 769,000 women
