Energy Systems
A basketball player makes a maximal 3-second sprint to intercept a pass. Name the energy system.
What is ATP.
This component of fitness is the ability to perform movement rapidly.
What is speed.
This training method involves maintaining exercise continuously without planned rest periods and is commonly used to develop aerobic capacity.
What is continuous training.
This training principle means that training should be relevant to the energy system, movements and fitness requirements of the activity.
What is specificity.
This term describes the number of times training occurs within a particular period.
What is frequency.
During a 20-second maximal cycling sprint, the athlete rapidly needs to resynthesise ATP using this system.
What is the ATP-PC system.
This component of fitness is the ability of a muscle or muscle group to exert force against resistance.
What is strength.
This training method involves alternating periods of work and recovery, with the work-to-rest ratio able to be manipulated.
What is interval training.
This principle refers to the planned, gradual increase in training load so that fitness continues to improve.
What is progressive overlaod.
This term describes the magnitude of exertion required during a training session.
What is intensity.
A 1500 m runner increases their pace during the final 300 m. The sudden increase in intensity requires a greater contribution from this energy system.
What is the lactic acid system.
This physiological measure represents the maximum rate at which oxygen can be taken in and utilised during exercise.
What is VO2max.
This training method involves changing intensity and duration throughout a session, often in response to variations in terrain or environment.
What is fartlek.
This principle recognises that training programs should consider an athlete's individual needs, goals, fitness level, motivation and skills.
What is individuality.
An athlete completes repeated 40 m sprints followed by 2 minutes of recovery. The relationship between the duration of work and duration of recovery is represented by this term.
What is work to rest ratio.
During a 10 km run, an athlete spends most of the event at submaximal intensity but occasionally increases intensity above the aerobic threshold. These are the two energy systems that would make the greatest contribution.
What is the aerobic and lactic acid system.
This physiological point occurs when blood lactate begins accumulating faster than it can be removed, limiting the ability to sustain increasing exercise intensity.
What is lactic threshold.
This training method uses stations or exercises arranged in a sequence to develop specific components of fitness.
What is circuit training.
This concept describes the reversal of training adaptations when an athlete stops training or significantly reduces their training load.
What is reversibility.
A coach examines an athlete's performance data, identifies that repeated high-intensity efforts are a major demand, and selects interval training to address this demand. This process demonstrates this QCAA assessment skill.
What is applying/synthesising data to devise a training strategy.
During a long-duration event, an athlete changes repeatedly between lower and higher intensities. The changing contribution of the aerobic and anaerobic systems demonstrates this concept.
What is the interplay of energy systems.
An endurance athlete has improved the amount of blood ejected from the heart with each beat. This adaptation increases this measure of the volume of blood pumped by the heart per minute.
What is cardiac output.
This variation of interval training involves repeated high-intensity efforts with relatively short recovery periods and is designed to place substantial demands on specific energy systems and fitness components.
What is high-intensity interval training.
This process sequences different training phases across an annual plan, including preparatory, pre-competition, competition and transition phases.
What is periodisation.
A coach identifies that an athlete's training program has insufficient specificity for the demands of their sport, modifies the program and uses performance data to explain why the modification should improve performance. This higher-order QCAA process involves these three actions.
What are analysing, evaluating and justifying.
