Chronic Adaptations To Strength Training Flashcards
What are the two measurements of fatigue?
Magnitude
Source/Mechanisms
Adaptation
Body adapts to new stimulus, if muscle fibres are not recruited they are not trained
What are four training methods that have shown a significant improvement in strength?
- Iso-inertial Training
- “metric
- “kinetic
- Neuromuscular Electrical Stimulation
Factors affecting adaptation
Nutritional status
Training programme
Concurrent activities
Age
Training history
Gender
Genotype
Power training increases what three things?
- Neural drive
- Force
- RFD
Strength training increases what four things?
- Neural drive
- Force
- RFD
- Muscle thickness

Hypertrophic response is affected by what things?
Training programme design
Contraction type – importance of eccentric contractions
Age
Gender
Concurrent training
Upper vs. lower body, Muscle group
Region of muscle
Nutritional status
Effects of muscle strengthening on vertical jump height: a simulation study
Increased strength did not improve vertical jump height when coordination was not optimised
When strength and coordination was optimised, there was a marked increase in jump height
Explosive movements rely heavily on preprogrammed muscle activation patterns – optimising takes several weeks
Strength training should be accompanied by practice
Co-activation of sprinter and distance runner muscles in isokinetic exercise
- Hamstrings considerably more active in knee extension than the quadriceps in knee flexion
- Coactivation of the sprinters hamstrings was four times that of distance runners
Reduced Co-activation of Antagonists will theoretically result in what?
Increase in net torque
Most studies comparing training methods have displayed what?
Contraction specificity
The traditional time-course model dictates that strength training results in mainly ** **** in the first * to * weeks of training and ** *** during the later * to * weeks of training
The traditional time-course model dictates that strength training results in mainly neural adaptations in the first 6 to 8 weeks of training and muscular adaptations during the later 8 to 12 weeks of training
Increases in muscle size following strength training are thought to mainly result from what?
Fibre hypertrophy – with preferential hypertrophy of type ll fibres occurring.
Evidence also exists for non-hypertrophic muscular adaptations which include…?
Fibre sub-
type transformations
Changes in muscle architecture
Tendon adaptation
