Effects of strength and aerobic training in children Flashcards
Two factors that increase muscular strength in children as they grow?
Size-dependent factors and size-independent factors
At what ages does muscular strength typically peak?
between 20-30
In prepubescent children, strength gains following RT are mainly attributed to?
Neural involvement rather then hypertrophy
Increases in isometric and dynamic leg strength are associated with an…
Increase in voluntary activation of agonist muscles
What were the correlations found between initial strength and gait speed?
RT led to an increase in knee extensor strength of 174 +/- 31% which was attributed to both hypertrophy and neuromuscular adaptations. Gait improved 48% following training
During maturation, motor neuron impulse frequency may be response for?
Increases in utilisation of type 2 motor units and also transformation of type 1 to type 2 fibres during growth
Changes that occur in nerve conduction velocity in children?
NCV in lower limbs decreases with age, but in upper limbs; small increase with age
Sprint speed over a given distance progressively improves during childhood because?
Stride length increases?
