• Personality is the patterns of thought and actions which make us unique as people.  
• An ergogenic aid is classed as ‘a substance, object, or mineral used to improve or enhance performance’. 
• The glycotic system is fueled by glucose. PFK  reacts with glucose to form pyruvic acid, which releases enough energy to resyntheses to moles of ATP in an endothermic reaction. However, because this reaction happens so quickly, there is no time to breakdown glucose and PA forms into lactic acid. If this accumulates the performer may experience OBLA (onset of blood Lactate accumulation
• Adaptations due to strength training can be: increased bone density, increased muscle mass, increased enzyme activity, it also strengthens connective tissues, which will help to prevent injury within rugby players
• Aerobic adaptations: strengthens respitory muscles which can increase tidal volume and utilization of oxygen
• Cardiovascular adaptations: Increased elasticity of arterial walls which improves efficiency of vascular shunt and cardiac output. As well as increasing strength of connective tissue and bone density which improves joint stability and prevent injury. 
• FOG fibre types have a large neuron size, and many fibres per neuron. They also have a large capillary density to allow more oxygen to the muscles to help prevent build up of lactic acid.  
• What occurs at the elbow joint during the preparatory phase of a pass?

  Flexion and extension
• In which plane does flexion and extension occur at the elbow joint?

  Sagittal plane
• Which bones articulate at the elbow joint?

  Ulna, radius, and humerus
• What type of joint is the elbow joint?

  Hinge joint
• What is the agonist muscle during the preparatory phase of a pass?

  Biceps brachii
• How does the biceps brachii contract during the preparatory phase?

  Concentrically
• How does the triceps brachii contract during the preparatory phase?

  Eccentrically
• • During the first stage of taking a step when running, there is extension at the knee joint, where the rectus femoris is the agonist and contracts concentrically, and the bicep femoris relaxes. The fixator is the iliopsoas and gluteal which contract isometrically.  
  • Then as you draw your leg back to bring yourself forward, flexion occurs at the knee joint, the biceps femoris acts as the agonist as it contracts concentrically and the rectus femoris is the antagonist contracting eccentrically. 
  • This is done in the frontal plane 
• Why do the biceps brachii and triceps brachii contract in different ways during the preparatory phase?

  To maximize force and accuracy
• What happens during the execution phase of a pass?

  Extension occurs with hands pointing towards target
• Which muscle becomes the agonist during extension in the execution phase?

  Triceps brachii
• How does the triceps brachii contract during extension?

  Concentrically
• What is the role of the biceps brachii during extension?

  It acts as the antagonist
• How does the biceps brachii behave during extension?

  It lengthens
