Pacing Flashcards
What is an even-pace pacing strategy?
Jump up to race pace ad hold from start to finish
What is a fast-pace/positive pacing strategy?
Start at a higher velocity and slowly drop
What is an all-out pacing strategy?
Race begins at a low velocity and increases over time
may be adopted in extreme environmental conditions
How can pacing strategies be measured?
Traditionally with splits but can also use power meters on bikes etc
What is the conventional pacing strategy for short duration events (< 1 min)?
All-out
get out fast and maintain high velocity
work on speed and endurance to reduce the drop off
What is the conventional pacing strategy for short duration events (1-5 min)?
Even pace is not best
fast/all-out start is preferred in many sports
What is the mechanism behind the all-out start strategy
Ergogenic in increasing oxidative energy contribution, meaning less anaerobic (less glycogen used and less accumulation of metabolites)
How does stimulation of O2 consumption effect mitochondria?
Chnages in extramitochondrial phosphorylation potential - ATP/ADP/Pi
What is the influence of work-rate on regulators of oxidative phosphorylation?
Higher ADP accumulation during higher-intensity exercise
Similiar responses for Pi
Mucle PCr declines faster during high-intensity exercise
What are the limitations of an extended all-out period?
initial muscle alkalosis due to CK then pH declines reflecting a after rate of muscle glycogen depletion
What are the strengths and weaknesses of leading the pack?
better running eceonomy, can choose shortest distance to run, set the pace but wind resistance
What are pacing strategies like when the race is > 5 min?
More irregular strategies
often involve an even pace with an all-out sprint
Which supplements are beneficial for pacing?
Caffeine - yes
Caf/CHO gum, enhances performance but not overall times
What is the effect of combining all-out exercise within a warm up?
Following a 20-min recovery can be beneficial (seen in 4km race)
What is pacing like when events are > 30 min?
Those who maintain an even place with little variation from mean tend to do better
