Exercise test Prescrip Quiz

Physical Activity (PA)

is any bodily movement produced by skeletal muscle contraction that results in a substantial increase in caloric requirements over resting energy expenditure.

Exercise

is a type of recreation PA consisting of planned, structured, and repetitive bodily movement done to improve and/or maintain one or more components of physical fitness.

Energy Expenditure (EE)

the total amount of energy or calories your body uses to perform essential life functions, digest food, and engage in physical activity

Aerobic

PA that is oxygen dependent

Anaerobic

PA that is oxygen independent

Physical fitness

Outcome of PA and exercise. Attained set of attributes or characteristics individuals have or achieve that relate to their ability to perform PA and activities of daily living.

What are the four situational domains of Physical Activity context?

Recreation, Transport, Occupation, and Household.

Transportation PA

walking to work, walking to a bus stop to ride to work, or biking vigorously at a challenging pace to work.

Occupational PA

one of the largest components of PA-related expenditure; has declined over past 50 years –there are less labor-focused jobs.– This form of EE has declined 100+ calories/day over past 50 years.

Household PA

Gardening, cleaning, and childcare; has also declined in some populations over past 50 years.

Recreational PA

Leisure-time movement performed for enjoyment rather than obligation; Like Sports.

Metabolic equivalent (MET)

used to estimate the amount of oxygen and energy used by the body during PA.

1 MET equals to what?

where 1 MET equals resting oxygen consumption.

What is the standard MET value expressed in oxygen consumption per unit of body mass?

3.5 ml/kg/min.

what is the MET range for 'Light' intensity activity? Ex)walking

1.6 to 2.9 METs

What is the MET range for “Moderate’’ intensity activity? Ex) fast walk

3.0 to 5.9 METs

What is the MET range for “Vigorous” intensity activity? Ex) Running

≥6.0 METs

Sedentary Behavior

Any waking behavior characterized by an energy expenditure ≤1.5 METs while in a sitting, reclining, or lying posture.

Physical Inactivity

Not doing at least 150 total minutes of moderate intensity, or 75 minutes of vigorous intensity, PA per week for the past 3 months.

What is the formula used to calculate 'MET-minutes'?

MET level X Time

What is the minimum recommendation of MET time per week?

500-1000 MET-minutes per week

List the five components of Physical fitness

Flexibility, Muscular Fitness, Body composition, Neuromotor fitness, Cardiorespiratory fitness.

Cardiorespiratory

to supply oxygen to the body during sustained physical activity.

Muscular fitness

muscular endurance, strength, and power.

Flexibility

Joint’s ability to pass through a given range of motion (ROM) without significant impingement or restriction

Body composition

The relative amounts of muscle, fat, bone, and other vital parts of the body (i.e., organs, body fluids, water, etc.) mass.

Neuromotor fitness

Known as “skilled-related fitness”, Functional fitness encompassing motor skills like balance, agility, and gait speed.

Lean body mass

is fat-free tissue (muscle, bone, organs)

Fat mass

consists of adipose tissue (fat tissue).

What is the physiological role of 'Essential fat'?

It is required for normal physiological functioning and is found in the heart, lungs, and central nervous system.
