agility definition-

combines speed with flexibility allowing change of direction with maximal speed and control

two factors effecting agility-

1. muscle fibre type- greater percentage of fast-twitch fibres will increase agility and generate force production.

2. reaction time- the faster the reaction time, greater the agility.

energy system and fitness test being used for agility=

ATP-PC system- cause of short bursts and explosive

Illinois agility test- helping netball player to do sharp pivoting and explosive dodging.

speed definition-

combines rate of motion and ability to move the body as quick as possible from one point to another

two factors effecting speed-

flexibility- greaten the flexibility or stride creating greater speed

reaction time- faster the reaction time, greater the speed.

energy system and fitness test being used for speed-

ATP-PC system- quick leads or explosive jumping for rebounds as a defender. or Anaerobic glycolysis system- high intensity for stop and go movements.

20 metre sprint test- drives physiological adaptations that makes you faster during netball game.

muscular power definition

refers to the ability of a muscle or group of muscles to exert a maximum amount of force in a certain period of time.

factors effecting muscular power

cross section area- allows the larger muscle groups to create greater power potential

speed of muscle contraction- faster the muscle contracts the more power it produces.

energy system and fitness test being used for muscular power

ATP-PC system- as it provides instant, peak muscular power and oxygen free energy bursts.

vertical jump test- directly evaluates a netball player’s lower-body explosive power and muscular strength.

aerobic power definition-

the maximum rate of energy production from the aerobic energy system.

factors effecting aerobic power

age- peaks in mid 20s and decreases with age

sex- males often have higher aerobic power then females due to greater size of lungs.

energy system and fitness test used for aerobic power

aerobic system- assists as engine for match play. It provides the sustained energy required to cover the court over 60 minutes.

VO2 max test (treadmill)- measures a netball player’s aerobic capacity and efficiency. It identifies exactly how much oxygen the body can use during intense exercise.

physiological and psychological perspectives

Physiological- physiological perspectives should be taken into account as current fitness and health outcomes. One of the best ways to gain this information is through completing a pre-participation health screening (PAR-Q).

Psychological- knowing the purpose of the testing for the individuals is an important step in this. A participant who knows their strengths and weaknesses may want to choose a different test to someone else → a questionnaire to determine psychological state of individual.
