test: training for strength Flashcards
define: strength
the ability to apply a force
what are the two types of strength?
in terms of movement
static and dynamic
define: static strength
the ability to apply a force against a resistance without any movement occurring
the muscle length remains constant
define: dynamic strength
the ability to apply force to overcome a resistance where movement occurs
the muscle length changes
what types of strength are there?
strength endurance
maximum strength
explosive/elastic strength
define: strength endurance
the ability to sustain repeated muscular contractions over a period of time
define: maximum strength
the ability to produce a maximum amount of force in a single muscular contraction
define: explosive/elastic strength
the ability to produce a maximal amount of force in one or a series of rapid muscular contractions
what are examples of strength endurance?
swimming
rowing
what are examples of maximum strength?
weight lifting
rugby
what are examples of explosive/elastic strength?
netball
long jump
what are the 2 factors that affect strength?
- the muscle fibre type being recruited
- the cross sectional area of the muscle
how does the muscle fibre type being recruited affect strength?
- fast glycolytic muscle fibres exert greater force with a faster speed of contraction than other fibre types
how does the cross sectional area of the muscle affect strength?
- the larger the cross sectional area of the muscle, the greater the strength or force of contraction
- age, gender and training all affect the cross sectional area of the muscle
what are the two tests for strength endurance?
abdominal curl test
press up test
