Muscular Strength and Endurance
People with high levels of muscular strength and endurance are able to perform daily tasks more efficiently. There are two types of muscular strength.
Muscular strengthThe maximum amount of force a muscle or muscle group can exert against an opposing force.
Term to Know

Muscular Strength and Endurance
Muscular endurance is measured by the amount of resistance (or weight) and the number of repetitions (or “reps”).
Muscular enduranceThe ability of the same muscle or muscle group to contract for an extended period of time without undue fatigue.
Term to Know
A person who can properly lift 75 pounds for 15 reps has greater muscular endurance than a person of the same gender who can only do 10 reps with the same amount of weight.

How and Why Muscles Grow
Other researchers contend that a person is born with his or her full number of muscle fibers.
Hypertrophy A thickening of existing muscle
fibers
Terms to Know
According to this view, muscle growth is due to hypertrophy.

FITT and the Principle of Overload
Improving flexibility means increasing FITT factors to achieve overload.
Never change all four FITT factors at the same time, and don’t change any factor too quickly.
![Page 26: What is Resistance Training? Benefits of resistance training Builds and tones muscles Improves metabolism Increases the strength of the tendons, ligaments,](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649d1b5503460f949f08ad/html5/thumbnails/26.jpg)
FITT and the Principle of Overload
Stretch at a minimum frequency of three days a week.
It is best to do some stretching daily.
![Page 27: What is Resistance Training? Benefits of resistance training Builds and tones muscles Improves metabolism Increases the strength of the tendons, ligaments,](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649d1b5503460f949f08ad/html5/thumbnails/27.jpg)
FITT and the Principle of Overload
Exercise care in establishing your intensity needs.
Your goal should be to reach the point where a muscle or connective tissue is stretched just beyond its normal resting state.
You should feel slight discomfort, but no pain.
![Page 28: What is Resistance Training? Benefits of resistance training Builds and tones muscles Improves metabolism Increases the strength of the tendons, ligaments,](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649d1b5503460f949f08ad/html5/thumbnails/28.jpg)
FITT and the Principle of Overload
The time duration of your stretches should begin at 20 to 30 seconds.
As your ROM increases, try to hold each stretch for 30 to 60 seconds, repeating three times per stretch.
![Page 29: What is Resistance Training? Benefits of resistance training Builds and tones muscles Improves metabolism Increases the strength of the tendons, ligaments,](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649d1b5503460f949f08ad/html5/thumbnails/29.jpg)
FITT and the Principle of Overload
To improve the flexibility of a particular joint or body area, you need to apply specificity.
That is, do stretches that affect the nerves, muscles, and connective tissues that control movement around a specific joint or body part.
![Page 30: What is Resistance Training? Benefits of resistance training Builds and tones muscles Improves metabolism Increases the strength of the tendons, ligaments,](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649d1b5503460f949f08ad/html5/thumbnails/30.jpg)
