Strength Flashcards
static strength (isometric)
ability to apply a force against a resistance without any movement
Dynamic strength (isotonic)
ability to apply a force to overcome a resistance where movement occurs
strength endurance
sustain repeated muscular contractions or single isometric contractions over a period of time
what is max strength
the max force the neuromuscular system can exert in a single contraction
explosive strength (elastic)
produce max force in one or a series of repeated muscular contractions
two factors effecting strength
- muscle fibre type being recruited
- cross sectional area of the muscle
muscle fibre type with the greatest speed and force or contraction producing the highest explosive and max strength
fast glycolytic fibres
5 methods of evaluating strength
- abdominal curl test (bleep test for sit ups)
- press up test (as many as possible)
- 1 rep max (testing strength of specific muscle group)
- grip strength dynamometer
- vertical jump test
1 advantage and 1 disadvantage
+ clear procedure gives valid and reliable results
- technique is open to interpretation so doest give reliable results
training to develop strength
- multigym (equipement with a range of stations)
- free weights (specific)
- plyometrics
- circuit training
LT adaptations muscle and connective tissue
- muscle hypertrophy
- muscle hyperplasia
- increased strength of ligaments and tendons
LT adaptations neural
- increased recruitment of motor units containing FG muscle fibres
LT adaptations metabolic adaptations
increased anaerobic fuel stores
- increased anaerobic enzyme activity
- improved buffering capacity
classifications of strength
max strength
elastic strength
strength endurance
relative strength is
the max force exerted relative to body weight or muscle size
how can overload be progressed
by increasing:
- number of reps of an exercise
- number of sets of the exercise
- intensity by a reduced recovery time
