Measuring and evaluating fatigue in sports performance Flashcards
Describe the training process
External load + player characteristics = internal load
Name the training adaptations
Speed and acceleration Agility Muscular strength and power Prolonged intermittent running Technical/tactical skills Repeated effort ability
Name the training modalities
Speed Strongman Conditioning SSG Skills Wrestle
Define internal load
Single or multiple physiological, psychological or mechanical stressor as a stimulus that is applied to a human biological system
What 4 systems do we want to stress?
Cognitive
Cardiovascular
Musculoskeletal
Neuromuscular
What does internal load produce?
Training adaptation
Performance
Injury
What does the graph of fitness and fatigue show?
Fatigue is high in amount but drops off quickly
Fitness less in amount but lasts longer
What does physical performance equal?
Fitness - fatigue
What is fatigue?
Reductions in physical and cognitive function that extend from an exercise-induced impairment of motor-performance through to sensations of tiredness and weakness that accompany some clinical conditions
What categories can fatigue be split into?
Perceived fatigability - homeostasis, psychological state
Performance fatigability - contractile function, muscle activation
What are the causes of transient fatigue (<80mins)?
Acidosis
Substrate depletion
Electrolyte disturbance
Dehydration
What are the causes of acute fatigue (>80mins <72hrs)?
Micro trauma caused by ECC muscle actions during running
Blunt trauma during tackles and collisions
What are the causes of chronic fatigue (>72 hours)?
Inadequate recovery
Excessive training and playing volume/loads
External factors
Should we avoid fatigue?
We need fatigue in order to disrupt homeostasis, super-compensate and then permit adaptation to our psycho-physiological and/or biomechanical systems
How do we make a decision about external load?
