Chronic Adaptations To Strength Training

Question 1

Measurements of Fatigue?

Answer 1

Magnitude of fatigue

Source of fatigue

Question 2

Why Measure fatigue?

Answer 2

Perfromance

Injury

Question 3

Improvements in strength training have been observed through

Answer 3

Iso-inertial training
Isometric Training
Isokinetic Training
Neruromusclular electrical simulation

Question 4

Best method of training to improve strength

Answer 4

Iso-inertial Training

Due to eccentric, concentric contractions

Question 5

Factors Affecting Adaptaions?

Answer 5

Nutritional Status
Training Programme Design
Concurrent Activities
Age
Training History
Gender

Question 6

Time course of adaptations

Answer 6

6-8 Weeks - Neural Adaptations

8-12 Weeks - Muscular Adaptations

Question 7

De Freitas et al 2011

Answer 7

Used Weekly training
Measured Responses over 8 weeks
Used CT scanning

Question 8

Muscle Hypotrophy in which fibres

Answer 8

In Type I and Type II

Question 9

What is Cell Hyperplasia?

Answer 9

When cells split into more cells

Question 10

What type of contraction is key to muscular Hypertrophy?

Answer 10

Eccentric contractions

Question 11

Stimuli for muscle hypertrophy?

Answer 11

mTor signalling
Metabolite Accumulation
Training Intensity
Muscle Activation

Question 12

Blood Flow restriction

Answer 12

Has been shown to increase muscle size and strength when used in conjunction with load-load resistance exercise

Question 13

Sarcopenia

Answer 13

loss of muscle mass with ageing

Question 14

What picture does Ultrasound produce?

Answer 14

Cross sectional pictures

Question 15

Strength improvements in the absence of increase in muscle size may result from?

Answer 15

Non-hypertrophic muscular adaptations

Neural adaptations

Question 16

Mechanical Adaptations

Answer 16

Peak Force
Rate of force development
Jump performance

Question 17

What is not a variable that can not be measured during an isometric assessment?

Answer 17

Peak Force

Question 18

Reduced Co-activation of antagonists

Answer 18

Will result in increase in net torque

may be adaptation to skilled performance

Question 19

Gender differences in co-activation

Answer 19

Females have greater due to greater joint laxity

Question 20

Renshaw cells

Answer 20

Involuntary Regulates muscle activation

Question 21

Factors affecting high rates of hamstring recurrence

Answer 21

Reduced flexibility
Muscle Weakness
Selective hamstring atrophy
avoidance of excessive stretch

Question 22

Techniques used for measuring neural change

Answer 22

Surface EMG
Twitch Interpolation
H-reflex, M-wave

Question 23

Increase in nerual drive

Answer 23

Increased motor unit recruitment
Increased firing frequency
Increased synchronisation
