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.
