EXSC 201 Physical Activity Concepts

Study Notes

Physical Activity

Defined as bodily movement produced by skeletal muscle contraction, increasing energy expenditure beyond basal levels.
Categories include mode, intensity, and purpose, with modes defined as types of activity.
Purposes can be occupational, leisure, household, self-care, and transportation.
Exercise participation may be analyzed separately from leisure-time activities.

Exercise

A planned, structured, repetitive type of physical activity aimed at improving or maintaining physical fitness.
Often referred to as exercise training, emphasizing leisure activities for health benefits.

Activities of Daily Living (ADLs)

Essential tasks for daily living encompassing eating, bathing, toileting, dressing, and basic mobility.

Aerobic Exercise (Training)

Focuses on aerobic energy systems, enhancing capacity and efficiency, notably improving cardiorespiratory endurance.

Anaerobic Exercise (Training)

Utilizes anaerobic energy systems to enhance capacity and acid-base balance tolerance during high-intensity exertion.

Balance Training

Involves static and dynamic exercises to improve stability against postural challenges and environmental factors.

Endurance Exercise (Training)

Characterized by repetitive dynamic contractions of large muscle groups over extended periods, including activities like running and cycling.

Flexibility Exercise

Aims to improve joint range of motion through specific stretching exercises.

Instrumental Activities of Daily Living

Activities promoting independent living such as meal preparation, financial management, and housework.

Leisure-Time Physical Activity

Voluntary activities beyond essential daily tasks, encompassing sports, exercise, and recreational pursuits.

Lifestyle Activities

Everyday tasks contributing to energy expenditure, such as walking instead of driving or taking stairs over elevators.

Resistance Training

Focused on increasing skeletal muscle strength, endurance, power, and mass through weight or resistance exercises.

Accumulation

Concept of reaching physical activity goals by performing short activity bouts throughout the day, e.g., three 10-minute sessions to meet a 30-minute goal.

Dose

Refers to the amount of physical activity, comprising frequency, duration, and intensity.
Frequency is the count of sessions per day/week; duration is the time spent in each bout; intensity reflects the energy required for the activity.

Dose Response

Describes the relationship between physical activity dose and specific health or fitness outcomes.
