1
Q

Physical Activity

A

Any body movement carried out by the skeletal muscles and requiring energy.

2
Q

Exercise

A

Planned, structured, repetitive movement of the body designed to improves or maintain physical fitness.

3
Q

Health-related fitness

A

Physical capacities that contribute to health: cardiorespiratory endurance, muscular strength, muscular endurance, flexibility, and body composition.

4
Q

Cardiorespiratory endurance

A

The ability of the body to perform prolonged, large-muscle, dynamic exercise at moderate-to-high levels of intensity

5
Q

Muscular Strength

A

the amount of force a muscle can produce with a single maximum effort

6
Q

metabolism

A

the sum of all the vital processes by which food energy and nutrients are made available to and used by the body

7
Q

Muscular Endurance

A

the ability of a muscle or group of muscles to remain contracted or to contract repeatedly for a long period of time

8
Q

Flexibility

A

the range of motion in a joint or group of joints, flexibility is related to muscle length

9
Q

body composition

A

the proportion of fat and fat-free-mass (muscle, bone, and water) in the body

10
Q

fat-free mass

A

the nonfat component of the human body, consisting of skeletal muscle, bone and water

11
Q

skill-related fitness

A

physical capacities that contribute to performance in a sport or activity: speed, power, agility, balance, coordination, and reaction time

12
Q

physical training

A

the performance of different types of activities that cause the body to adapt and improve its level of fitness

13
Q

specificity

A

the training principle that the body adapts to the particular type and amount of stress placed on it

14
Q

progressive overload

A

the training principle that fitness improvements are lost when demands on the body are lowered

15
Q

exercise stress test

A

a test usually administered on a treadmill or cycle ergometer that involves analysis of the changes in electrical activity in te heart from an electrocardiogram (EKG or ECG) taken during exercise. Used to determine if any heart disease is present and to assess current fitness level.

16
Q

graded exercise test (GXT)

A

an exercise test that starts at an easy intensity and progresses to maximum capacity

17
Q

overtraining

A

a condition caused by training too much or too intensely, characterised by lack of energy, decreased physical performance, fatigue, depression, aching muscles and joints, and susceptibility to injury.
