HTH 100 Ch. 7 Flashcards
(30 cards)
Physical Activity
Refers to all body movements produced by skeletal movements produced by skeletal muscles, resulting in substantial increases in energy expenditure
Exercise
Planned, structured, and repetitive bodily movement done to improve or maintain one or more components of physical fitness
Sedentary
Activity that expends no more than 1.5 times the resting energy level while seated or reclined
MET
A metabolic equivalent or resting level of energy expenditure (3.5 ml · kg^-1 · min^-1)
Physical Fitness
A balance of health-related attributes that allows you to perform moderate to vigorous physical activities on a regular basis and complete daily physical tasks without undue fatigue
Cardiorespiratory Fitness
The ability of the heart, lungs, and blood vessels to supply oxygen to skeletal muscles during sustained physical activity
Aerobic Exercise
Prolonged exercise that requires oxygen to make energy for activity
Aerobic Capacity (Power)
The functional status of the cardiorespiratory system; refers specifically to the volume of oxygen the muscles consume during exercise
Muscular Strength
The amount of force that a muscle is capable of exerting in one contraction
Muscular Endurance
A muscle’s ability to exert force repeatedly without fatiguing or the ability to sustain a muscular contraction for a length of time
Flexibility
The range of motion, or the amount of movement possible, at a particular joint or series of joints
Body Composition
The relative proportions of fat and fat-free (muscle, bone, water, organs) tissues in the body
FITT
Acronym for frequency, intensity, time, type; the terms that describe the essential components of a program or plan to improve a health-related component of physical fitness
Frequency
As part of the FITT prescription, refers to how many days per week a person should exercise
Intensity
As part of the FITT prescription, refers to how hard or how much effort is needed when a person exercises
Time
As part of the FITT prescription, refers to the duration of an exercise session
Type
As part of the FITT prescription, refers to what kind of exercises a person needs to do
Target Heart Rate
The heart rate range of aerobic exercise that leads to improved cardiorespiratory fitness (64% to 96% of maximal heart rate)
Perceived Exertion
The subjective perception of effort during exercise that can be used to monitor exercise intensity
One Repetition Maximum (1 RM)
The amount of weight or resistance that can be lifted or moved only once
Static Stretching
Stretching techniques that slowly and gradually lengthen a muscle or group or muscles and their tendons
Dynamic Stretching
Gradual transitions in movement and body position that progressively increase the range of motion through repeating the movements
Hyponatremia or Water Intoxication
Overconsumption of water, which leads to a dilution of sodium concentration in the blood, with potentially fatal results
Traumatic Injuries
Injuries that are accidental and occur suddenly
