Any bodily movement produced by the contraction of skeletal muscles that increases energy expenditure above resting levels
Exercise
Planned and structured repetitive movements of physical activity in order to improve or maintain one or more characteristics of physical fitness
Physical Fitness
A group of characteristics a person possesses/achieves related to physical activity:
Cardioresperatory Fitness
Muscle strength
Muscle Endurance
Flexibility
Body Composition
Overload
Increase in stimulus beyond normal to impose demands on the body system to create adaptation
Threshold
Minimum amount of overload required to bring about change.
Excessive Overload
Overuse/injury
Principiles of Training
Specificity
Progression
Overload
Reversibility
Specificity
SAID
The body will adapt to specific training stimuli with specific physical and physiological adaptations
Progression
Incremental increases in workload over period of training
Tissue Adaption/ Remodeling
Stimulus creates demand
Body repairs/remodels
Remodel rate > tissue damage: adaptation occurs
Remodel rate< tissue damage: overuse/injury
Muscular strength
the amount of force a muscle can exert in a single all-out effort (1 Rep Max/1RM)
Muscular Endurance
Muscle's ability to perform multiple submaximal contractions or hold a static contraction
Flexibility
Refers to a joint's Range Of Mobility-ROM
Body Composition
Relative proportion of fat (fat mass) and fat-free (lean mass) tissue in the body.
Cardiorespiratory Fitness
Ability to perform large muscle, dynamic, moderate to high intensity exercise for prolonged periods of time and reflects the functional capabilities of the heart, blood vessels, blood, lungs and relevant muscles during various exercise demands.
Metabolic Equivalent MET
A measure of exercise intensity based on oxygen consumption
