Physical Activity

Any bodily movement produced by the contraction of skeletal muscles that results in a substantial increase in caloric requirements over resting energy expenditure (REE)

Exercise

Consisting of planned, structured, and repetitive bodily movement done to improve and/or maintain one or more components of physical fitness

Physical Fitness

A set of attributes or characteristics, individuals have or achieve that relate to their ability to perform PA and activities of daily living (Health and Skill Related)

Health Related Components

• Cardiorespiratory endurance

• Body composition

• Muscular strength

• Muscular endurance

• Flexibility

Skill Related Components

• Agility

• Coordination

• Balance

• Power

• Reaction time

• Speed

Cardiorespiratory Endurance

the ability of the circulatory and respiratory systems to supply oxygen during sustained physical activity

Body Composition

the relative amounts of fat and non-fat mass in the body, which influence overall health and physical performance.

Muscular Strength

the ability of muscle to exert force

Muscular Endurance

the ability of muscle to continue to perform without fatigue

Flexibilty

the range of motion available at a joint

Agility

the ability to move quickly and change direction with precision.

Cooridination

the ability to use the senses such as sight and hearing together with body parts in performing tasks smoothly and accurately

Balance

the maintenance of equilibrium while stationary or moving

Power

the ability or rate at which one can perform work

Reaction Time

the time taken to respond to a stimulus.

Speed

The ability to move quickly or cover distance in a short amount of time.

Intensity

How much effort or energy your body expends during physical activity (how hard it would be).

3.5 ml O₂ per kg body weight per min

One metabolic equivalent (MET) is defined as the amount of oxygen consumed while sitting at rest and is equal to __

Light Intensity

1.6-2.9 METs __

Moderate Intensity

3.0-5.9 METs __

Vigorous

≥ 6.0 METs __ 

longer in duration, greater intensity, or both

Individuals who maintain a regular level of physical activity are likely to derive greater health benefits than those who have lesser amounts, if __

moderate amount

Important health benefits can be obtained by performing a __ of physical activity on most, if not all, days of the week.

150 min to 300 min

For substantial health benefits, adults should do at least __ of moderate intensity
