Factors Affecting Performance Flashcards
What are the physiological adaptations in response to training?
ACRONYM?
RANDOM STORIES OFTEN HAVE MEMORABLE ENDINGS
Resting heart rate
stroke volume and cardiac output
oxygen uptake and lung capacity
Haemoglobin level
Effect on fast/slow muscle twitch fibres
Resting heart rate
Response to training?
Principles associated
Number of heart contractions per minute while resting
Response to training - greater oxygen transport = contract less frequently
Principles = progressive overload, training thresholds
Stroke Volume & Cardiac Output
Response to training?
Principles associated
Stroke Volume - amount of blood ejected by the left ventricle
Cardiac output - volume of blood ejected per minute (HR X SV)
Response to training? Thicker/stronger heart+walls –> more blood to enter the heart –> available to muscles
Principles = progressive overload, specificity, training thresholds
Oxygen uptake and lung capacity
Response to training?
Principles associated
Oxygen uptake - ability to absorb oxygen through the lungs to blood
Lung capacity - amount of air that can be passed in and out of the lungs
Response to training?
Greater supply of oxygen = greater performance
Principles = progressive overload, training thresholds
Haemoglobin
Response to training?
Principles associated
A molecule in red blood cells that transports oxygen around the body
Response to training?
Increases oxygen carrying capacity of blood. Allows retention of higher intensity for longer periods of time (longer to reach anaerobic threshold)
Principles = progressive overload, specificity
Muscle Hypertrophy
Response to training?
Principles associated
Increase in diameter of muscle + size of muscle cells
Response to training?
Result of resistance training → repeated contraction cause damage → repaired with new fibres
Increase muscular strength/endurance → exert greater force + increase muscular contraction speed
Principles = progressive overload, specificity, variety
Effect on fast/slow twtitch muscle fibres
Response to training?
Principles associated
Slow Twitch = contract slowly, release energy gradually (aerobic system)
Fast Twitch = contract quickly, get tired quickly, explosive activities (anaerobic systems)
Response to training?
Repeated engagement = make more efficient at role E.g. fast: increased glycogen/ATP stores, slow: rely on oxygenated blood to create energy
PRINCIPLES = specificity, variety
Psychological strategies to enhance motivation and mangage anxiety
