physiological adaptations from strength training

Question 1

what are neural structural adaptations

Answer 1

-increased recruitment of motor units
-decrease inhibition of stretch reflex

Question 2

what is the functional effect of increased recruitment of motor units

Answer 2

increased force of contraction
-improved coordination of motor units

Question 3

what is the functional effect of decrease inhibition of stretch reflex

Answer 3

increases force of contraction from agonist
-decrease inhibition of antagonist
-increase stretch from antagonist

Question 4

what are structural adaptations of muscular and connective tissue adaptations

Answer 4

-muscle hypertrophy
-increased bone density
-increased strength of ligaments and tendons
-increased size of contractile proteins and myofibrils

Question 5

what is the effect of muscle hypertrophy

Answer 5

-increase force of contraction
-max and explosive training will increase size of FG
-strength endurance training will increase size of FOG fibres

Question 6

what is the effect of increased bone density and mass

Answer 6

-increase absorption of calcium
-decreases risk of osteoporosis

Question 7

what is the effect of increase strength of ligaments and tendons

Answer 7

increase joint stability
-decrease risk of injury

Question 8

what is the effect of increased size of contractile proteins and myofibrille

Answer 8

increase force of contraction
-increase of actin myosin filaments and cross bridges
-increase protein synthesis

Question 9

what are structural adaptations of metabolic adaptations

Answer 9

-increase phosphocreatine, glycogen and ATP stores
-increase enzyme activity
-increase buffering capacity
-increase muscle mass

Question 10

what is the effect of increase phosphocreatine, glycogen and ATP stores

Answer 10

-increase capacity for alactic energy production
-increase speed energy

Question 11

what effect does increase enzyme activity have

Answer 11

-increase efficiency of anaerobic energy production
-increased activity of ATPase, créatine kinase
-reduces the onset of fatigue

Question 12

what effect does increased buffering capacity have

Answer 12

-increases tolerance and removal of lactic acid
-delay OBLA
-increase metabolic rate

Question 13

what effect does increased muscle mass have

Answer 13

-improve body composition
-increased metabolic rate
