Developing Max Power

Question 1

Elements for increasing muscular power

Answer 1

Strength, speed and a good strength-speed relationship

Question 2

What factors influence the ability to generate max power?

Answer 2

Muscle morphology,
Muscle mechanics,
Neural factors,
muscle environment

Question 3

Which muscle fibre is recruited first eg. Whilst holding a weight

Answer 3

IIb as they are high force however they are also high fatigue so then IIa and I are recruited

Question 4

How might increasing firing freq increase the force generated by a muscle?

Answer 4

It increases the rate at which muscle action potentials stimulate the muscle fibre, at shorter intervals the relaxation between contractions diminishes (summation), resulting in a stronger force and tetanus

Question 5

What is tetanus?

Answer 5

State of max contraction

Question 6

What’s intermuscular co-ord and intramuscular co-ord?

Answer 6

Inter - between the diff muscles in the body eg. Agonists and antagonist
Intra - between the indiv fibres in the muscle eg. MU recruitment and FF
