Lecture 23 : Tapering Flashcards
(51 cards)
what is tapering
strategic reduction in training load before competition to reduce accumulated fatigue, optimise physiological adaptations and peak performance
training adaptations are masked by … and what does tapering do to help this
training adaptations are masked by fatigue, tapering removes fatigue to reveal peak capacity
peak performance usually occurs wehn
7-14 days after beginning tapering
4 physiological mechanisms behind tapering (well 4 like categories - examples within them)
decreased cortisol, increased testosterone = improved hormonal profile
increased glycogen resynthesis and mitochondrial efficiency
decreased inflammation, increased muscle contractile properties
improved HRV, parasympathetic recovery
what happens to fibre types in tapering
get a shift to type IIx
tapering reduces …
CNS stress > restores neural drive and motor cortex excitability
this is due to reduction in cortisol
tapering reduces CNS stress which leads to improved
motor unit recruitment
rate coding (faster firing rate)
synchonrisation of motor units
inter-muscular coordination
tapering increases
rate of force development
what are the mechanisms of tapering that lead to increased rate of force development
reduced neuromuscular inhibition
improved muscle stiffness and tendon compliance
enhanced firing speed of fast twitch fibres
lower muscle damage from tapering means
clearer neuromuscular signalling
reduced co-contraaction from tapering means
better economy of movement
why is tapering important (3 reasons)
reduces fatigue while maintaing or even increasing fitness (fitness fatigue model)
improves neuromuscular function, psychological readiness and technical sharpness
leads to supercompensation : enhanced performance due to reduced training stress + recovered symptoms
essential components in tapering include a change in one of what three variables
volume
frequency
intensity
best performance outcomes occurred in a study when volume intensity and frequency were altered how in taper
volume : reduced by 41-60%
intensity : maintained or slightly increased
frequency : reduced by <20%
why reduce volume and not intensity
volume reduces cumulative fatigue
why is intensity maintained or slightly increased in tapering
preserves CNS adaption like power (higher decay rates)
competition ready : we want them training at competition intensity, you need to train the way you will compete
frequency reduced by <20% in tapering keeps ….
technical and skill elements sharp
what happens if you reduce both volume and intensity
leads to neuromusclar detraining
what happens in people who detrain compared to those who taper
people could maintain performance in tapering group where as detraining group had a decrease in performance
what are the physiological effects of reducing volume and intensity
decreased motor unit recruitment
decreased muscles stiffness
decreased rate coding
what are the psychological effects of reducing volume and intensity
psychological disengagement
decreased arousal
what are the three main tapering methods
linear
step
exponential
what is linear taper
gradual reduction in volume over time
long taper (2-4 weeks)
who is linear taper often seen
typically seen in more endurance athletes
