Skill-Related Flashcards
What is reaction time?
The time in between a signal being detected and the first movement to this signal
What are the factors which affect reaction time?
Distractions, number of responses and optimal concentration/arousal
How does concentration and arousal affect reaction time?
Concentration and arousal leads to quicker and appropriate reactions
How do distractions affect reaction time?
They add to reaction time and slow down responses
How does number of responses affect reaction time?
Reaction time is quickest when there is only one possible response
What is muscular power?
The ability to exert a maximal contraction in one explosive effort
What are the factors which affect muscular power?
Age, gender, fibre type and fibre recruitment
How does age affect muscular power?
It peaks around 25 years of age, and then declines by 1% per year
How does gender affect muscular power?
Males have greater muscle mass than females, therefore greater muscular power
How does fibre type affect muscular power?
Fast twitch fibres can generate muscular power quicker than slow twitch fibres
What is anaerobic capacity?
The ability to produce energy without using oxygen
What are the factors which affect anaerobic capacity?
Age, gender, fibre type and anaerobic training
How does age affect anaerobic capacity?
Anaerobic power tends to peak around 30 years of age and declines by 1% per year
How does gender affect anaerobic capacity?
Males have a greater muscle mass than females, so will have greater stores of anaerobic fuels
How does anaerobic training affect anaerobic capacity?
It greatly improves the muscle’s ability to tolerate the build-up of lactic acid, hydrogen ions and ADP
What is speed?
The ability to move the whole body, or body parts from one place to another in the shortest possible time
What are the factors which affect speed?
Reaction time, muscular strength, range of motion and fibre type
How does fibre type affect speed?
Fast twitch fibres generate greater speeds than slow twitch fibres
How does reaction time affect speed?
Faster reaction times contribute to quicker movement and speed
How does muscular strength affect speed?
The greater one’s muscular strength, the greater their speed will be
What is agility?
A rapid, whole body movement with a change in velocity or direction in response to a stimulus
What are the factors which affect agility?
Speed, reaction time, centre of gravity, range of motion and fibre type
How does centre of gravity affect agility?
Athletes with a lower centre of gravity tend to be more agile
How does reaction time affect agility?
Faster reaction times contribute to quicker movements and agility
How does range of motion affect agility?
The greater the range of motion, the more agile someone will be
What is coordination?
The ability to use the body’s senses to execute motor skills smoothly and accurately
What are the factors which affect coordination?
Sequencing of movements, stage of learning and practice
How does sequencing of movement affect coordination?
The more sequences to a movement, the higher the level of coordination required
How does stage of learning affect coordination?
Elite level performers are more coordinated than lower level performers
What is balance?
The ability to maintain equilibrium whilst stationary or moving
What are the factors which affect balance?
Base of support, centre of gravity and core stability
How does base of support affect balance?
The greater the base of support, the greater the equilibrium
How does centre of gravity affect balance?
By lowering one’s centre of gravity, balance is increased
How does core stability affect balance?
Greater core stability leads to improved balance
