Question Answer
PC stores MUSCULAR PC stores will increase. Greater capacity to work at maximum intensity as the ATP-PC system will remain dominant for longer
Glycolytic capacity MUSCULAR Enhanced muscular storage of glycogen and increases in the levels of glycolytic enzymes which increase the capacity of the anaerobic glycolysis system to produce energy without O2.
ATP stores MUSCULAR Increased stores of ATP within the muscles. Greater capacity to work at maximum intensity as the ATP-PC system will remain dominant for longer
ATPase & Creatine Kinase (enzymes) MUSCULAR Increased ATPase and Creatine Kinase (enzymes) result in an increased rate of ATP resynthesis through the breakdown of ATP and PC respectively.
Glycolytic enzymes MUSCULAR Increased Glycolytic enzymes Break down glycogen more efficiently, resulting in the quicker release of ATP for muscular contraction
Hypertrophy of the fast twitch fibres MUSCULAR Fast-twitch fibres increase in size, due to an increase in size and number of myofibrils. This results in an increase in strength and power.
Motor unit recruitment MUSCULAR Increased motor unit recruitment will result in more forceful contractions as more muscle fibres are involved in the action. One motor neuron and the attached muscle fibres make up one motor unit
Lactate tolerance MUSCULAR Lactate tolerance will increase. As a result of anaerobic training, your muscles have an increased ability to work at higher intensities in the presence of increased accumulation of metabolic byproducts.
Increased thickness of the left ventricle wall CARDIOVASCULAR Hypertrophy of cardiac muscle results in the blood being pushed out of the heart with greater force (also leads to a slight increase in SV) *no real benefit to performance*
Anaerobic training methods Plyometrics Short-Interval Intermediate-Interval Resistance Circuit*
