Exam 1 Flashcards
physical activity
bodily movement that is produced by the contraction of skeletal muscle and that substantially increases energy expenditure
exercise
a type of physical activity that is planned, structured, and repetitive bodily movement done to improve or maintain one or more components of physical fitness
physical fitness
a multidimensional concept; a set of attributes that people possess or achieve that relates to the ability to perform physical activity, and is comprised of sill-related, health-related, and physiologic components
health
the total of your physical, social, emotional, mental and spiritual status
wellness
having the components of health balanced and at sufficient levels
skill-related physical fitness
associated with sport and motor skill
health-related physical fitness
the ability to perform daily activities with vigor; also referred to as the components of fitness
physiologic fitness
non-performance components that relate to biological influenced by habitual activity
cardiorespiratory endurance
ability of the heart, lungs, and blood vessels to take in, absorb, and deliver oxygen to working muscles, allowing you to walk, run, swim, bike, climb stairs or mountains, and so forth
muscular strength
the maximal pulling force of a muscle or a muscle group
muscular endurance
the ability to move a weight repeatedly without fatigue
flexibility
the range of motion around a joint, or more simply the degree to which you can move your limbs with grace and efficiency
body composition
the relationship between fat mass and lean body mass
social health
the ability to interact well with people and the environment, and have satisfying interpersonal relationships
mental health
the ability to learn and grown intellectually
emotional health
the ability to control emotions so that you feel comfortable expressing them and can express them appropriately
spiritual health
a belief in some unifying force, which will vary person to person but will have the concept of faith at its core
tailoring
having programs specific to needs, fitness levels, and types of activity for individual
chaining
one behavior is linked to a similar behavior and so on
behavior change theory
help explain behavior and help change behavior; if we can explain why a behavior is adopted or not, we can intervene, control, or change that behavior
transtheoretical model
people are at different levels of readiness for change. strategies to facilitate behavior change should be specific to that level
health belief model
suggests other factors are significant determinants of activity
material reinforcement
rewarding positive behavior so behavior will be repeated
social reinforcement
having others pat you on the back for exercising regularly
self-monitoring
the process of observing and recording your own behavior
aerobic metabolism
when ATP is generated by the process of using oxygen
anaerobic metabolism
when ATP is generated without the use of oxygen
immediate energy system
used for high intensity activities that last less than 30 seconds; the muscles use ATP and creatine phosphate (CP) supplies that are already stored in the muscles (shorts & powerlifting)
lactic acid
generates ATP for high-intensity activities lasting from 30 seconds to 3 minutes; in general, events or activities that require a combination of speed and power over short time rely heavily on this system (400- and 800-meter sprints)
aerobic fitness
the ability of the heart, blood vessels and the lungs to deliver oxygen to the exercising muscles in amounts sufficient to meet the demands of the workload
VO2max
the optimal capacity of the heart to pump blood, of the lungs to fill with larger volumes of air, and the muscle cells to use the oxygen and remove waste products produced during process of aerobic metabolism
