Musculoskeletal System
This type of muscle action occurs when a muscle shortens to produce movement at a joint during physical activity
What is a concentric muscle action
This type of injury occurs suddenly and is often the result of a single traumatic event during physical activity
What is an acute injury
This training method uses continuous aerobic activity to improve cardiorespiratory endurance
What is Continous Training
his term describes the amount of blood pumped by the heart in one beat and increases during exercise
What is stroke volume
This term refers to the amount of air inhaled and exhaled in one breath and increases during exercise
What is tidal volume
This muscle fibre type is highly fatigue resistant and suited to sustained aerobic activity
What are Type I slow twitch muscle fibres
his type of musculoskeletal injury develops over time due to repetitive stress with inadequate recovery
What is a chronic overuse injury
This performance enhancing substance is prohibited because it artificially increases red blood cell production and poses significant health risks
What is erythropoietin EPO
These blood vessels have thin walls and are the site of gas exchange between the blood and working muscles
What are capillaries
This state occurs during sustained submaximal exercise when oxygen supply matches oxygen demand
What is Steady State
his principle explains how the agonist contracts while the antagonist relaxes to allow efficient movement at a joint
What is reciprocal inhibition
This intrinsic risk factor increases the likelihood of injury due to previous damage that has not fully healed
What is previous injury history
This performance enhancing method is permitted and improves oxygen availability through exposure to reduced oxygen environments
What is altitude training
This chamber of the heart receives deoxygenated blood returning from the body via the vena cava
What is the right atrium
This concept explains why aerobic energy production cannot immediately meet energy demands at the start of exercise
What is oxygen deficit
This class of lever is most common in the human body and favours speed and range of movement rather than force
What is a third class lever
This term describes an injury to a ligament caused by excessive stretching or tearing at a joint
What is a sprain
his principle emphasises that athletes should prioritise whole foods over supplements to safely support training and performance
What is Food First
This cardiovascular response explains how the heart lungs and blood work together to deliver oxygen and remove waste products to maintain aerobic performance
What is the cardiovascular system supporting oxygen delivery and waste removal during exercise
This structure of the respiratory system is the main site where oxygen and carbon dioxide are exchanged between the air and the blood
What are the alveoli
This theory explains how actin and myosin interact within the sarcomere to produce muscle contraction
What is the sliding filament theory
What are the four stages of rehabilitation that progress an individual from initial injury management to complete functional recovery
protection mobilisation
Open Closed exercises
Sport specific reconditioning
Maintenance prevention
This organisation is responsible for regulating anti doping globally and applies three criteria to determine whether a substance or method is prohibited in sport
What is the World Anti Doping Agency and the three criteria are that it could enhances performance poses an actual or potential health risk and violates the spirit of sport
Photo Question
A) Aorta
B) Left Atrium
C) Left Ventricle
D) Right Atrium
This part of the respiratory system includes structures such as the trachea bronchi and bronchioles and is responsible for transporting warming and humidifying air rather than gas exchange
What is the conducting zone of the respiratory system
