Question	Answer
Describe concurrent periodisation	Training multiple goals at the same time
Describe the post activation potentiation protocol	1rm back squat followed by explosive
During hypertrophy training mitochondria density decreases, capillary density decreases or remains the same	True
The athletes training status is defined as what?	An analysis of the athletes performance
The inhibition of type 1 motor units and the recruitment of those fibres required to facilitate and explosive response from the athlete describes what?]	Selective recruitment
Lactate can also be transported in the blood to the liver, where it is converted to glucose. This process is referred to as the Cori cycle	Muscle spindle adaptions with strength trainin
Mitochondrial density decreases Capillary density No change or decreases. What is this describing?	Muscular adaptions to hypertrophy
HIIT sprints and cycling significantly increase H+ buffering capacity	True
Anaerobic overtraining how it does not affect performance	Altered neuron function
With intramuscular EMG a needle electrode, or a needle containing two fine-wire electrodes, is inserted through the muscle of interest to accurately record localized motor unit action potentials	True
Surface EMG is often more effective for monitoring superficial muscle, as it is unable to bypass the action potentials of superficial muscles and detect deeper muscle activity	True
The force produced when both limbs contract together is lower than the sum of the forces they produce when contracting unilaterally. What does this describe?	Bilateral strength deficit in untrained individuals
Research has shown that the corresponding EMG activity is lower during bilateral contractions.	True
Results focused goals	Outcome goal
To improve the athletes individual performance	Performance goal
The athlete has control over skill, technique or strategy based	Process goal
Neural activation is higher during high intensity muscular efforts?	True
Only 71% of muscle tissue is activated during maximal efforts in untrained populations	True
Motor units are recruited in an ascending order according to their recruitment thresholds and firing rates. Which principle does this describe?	Size principle
Recruitment of high-threshold units to rapidly achieve more force and power. What is this the definition of?	Slective recruitment
Research has shown that as muscle size increases it does not require as much neural activation to lift a given load	True
Motor unit synchronization is potentially more critical to the timing of force production and less significant with regard to the overall level of force developed	True
The phosphagen or creatine phosphate system is also known as what system?	Anaerobic alactic
The glycolytic system is otherwise known as which system?	Anaerobic lactic
Exercises such as sprints and plyometric drills (10s work complete recovery) primarily stress which type of energy system?	Phosphagen system
Longer-duration interval-type with shorter rest of 20-60s uses which energy system?	Glycolytic system
Training one limb typically results in an increase in EMG activity in the untrained limb. What is this describing?	Cross education associated with resistance training
An increase in bone matrix density brought about by the elevated levels of collagen molecules. What is this describing?	Connective tissue adaptions
What are collegen fibres are laid down by?	Osteoblasts
Prepare, competition transition	Matveyev major divisions
Energy system,, movement pattern, training status, environment. What are these measures of?	Performance measures
Cortisol levels increase dramatically when rest periods are low and volume is high. What does this describe?	Cortisol response to training
Movement analysis, injury analysis, physiological analysis. What does this describe?	Sports analysis
Heavy strength training followed by plyometrics	Post activation potentiation
An increase in muscle isometric twitch and low frequency tetanic force following a conditioning actuvity	PAP
The rate at which nerve impulses arrive is known as what?	Motor unit firing rate
An increase in the angle of pinnation, myofibrillar volume and sarcoplasmic reticulum density. What is this describing?	Muscular adaptions associate with resistance training
Increased levels of testosterone, HGH and cortisol for up to 15-30mins.	Hormonal response to resistant training
Hydrogen ion accumulation may be a primary factor influencing growth hormone and cortisol release	True
Hypertrophy/endurance - strength - power - peaking	Linear training
Vertical jump, 1RM power clean, horizontal jump, Wingate ergometer test are tests for which component?	max power output
The manipulation of load according to the athletes subjective perception of the intensity of effort and effects of loading	Cybernetic periodisation
