LECTURE 13: Physiology and metabolic responses of repeated sprint activities
Repeated sprint ability
- The ability to perform repeated sprints with minimal recovery between sprint bouts
oScientific literature is growing
oThought to be an important aspect of team sport competition
- Physiological and metabolic responses of RSA will be influenced by variations in exercise
protocols
oIe how they train for RSA
- If the physiological and metabolic responses of RSA protocols are to be specific and relevant
to team based sports
oSprint and recovery patterns need to replicate the movement patterns in these
sports
oTraining principle of specificity
Repeated effort ability
- Ability to do repeated sprint activities with other activities as well
oBetter represents physiological demand
oIe hockey running with hockey stick
- RSA and REA are different
- addition of extra skills increases physiological response; its cognitively harder
movement patterns in field based team sports
- time motional analysis used to study distance and duration of common movement patterns
ostanding, walking, jogging, striding and sprinting
osome kill related activities ie tackle, ball, possession
- GPS
oMost common
oCommonly used to monitor training loads in athletes on a daily basis
oNeeds to be outside, radio waves interrupt signal
- Video analysis
- Manual
- Audio
- Use info to make program

RSA and fatigue
- Factors other than RSA contribute to decline in performance
oEnergy expenditure during eccentric contractions
In quads when running down a hill
oChange of direction movements
Large energy cost
oJogging or striding for extended periods
- Sprint metabolism
oConsiderable variation oin energy system contributions in the literature

Document Summary
Lecture 13: physiology and metabolic responses of repeated sprint activities. The ability to perform repeated sprints with minimal recovery between sprint bouts: scientific literature is growing, thought to be an important aspect of team sport competition. Physiological and metabolic responses of rsa will be influenced by variations in exercise protocols: ie how they train for rsa. If the physiological and metabolic responses of rsa protocols are to be specific and relevant to team based sports: sprint and recovery patterns need to replicate the movement patterns in these sports, training principle of specificity. Ability to do repeated sprint activities with other activities as well: better represents physiological demand, ie hockey running with hockey stick. Gps: most common, commonly used to monitor training loads in athletes on a daily basis, needs to be outside, radio waves interrupt signal. Factors other than rsa contribute to decline in performance: energy expenditure during eccentric contractions.
