Lactate threshold
Percentage of VO2 Max at which a specifice blood lactate concentration is observed or the point at which blod lactate concentration begins to increase above resting levels
Maximal lactate stedy state
The exercise intensity at which maximal lactate production ins equal to cleaarance
Wat is considered to be best indicator of aerobic endurance performance
Lactate steady state
Exercise eonomy
A measure of te energy cost of activity at a given exercise velocity
Aerobic endurance trainng variables (5)
Exercise mode, training frequency, training intensity, exercise duration, exercise progression
Exercise mode=
Specific activity performed (cycling, running, swimming)
How does training at a higher intensity and duration effect frequency of training sessions?
Less frequent sessions; more recovery
Injury rates are higher in endurance training when frequency is greater than ___ days per wk
5
Three things critical for recovery
Rehydration, refueling, obtaining sufficient rest
Effect of too high of an intensity and too low of an intnsity training seesion?
Too high results in fatigue and ends training session prematurely; to low does not overload the body's systems and induce physiological adaptations
Most frequently used method to assign aerobic intensity? WHy?
Heart rate; relationship to VO2 max
Heart rate reserve-
Maximal heart rate minus resting heart rate
Target heart rate calculations: Karvonen Method
Age predicted max heart rate (APMHR)= 220-ageAPMHR - resting hrt rate= heart rate reserve (HRR)(HRR x exercise intensity) + RHR= target heart rate
Use the Karvonen method to determine target heart rate for a 30 yr old athlete with RHR of 60beats/min and assigned to exercise intensity of 60-70% of functional capacity
220-30=190 ; 190-60 = 130 130 x (60-70%) + 60138-151 beats per min (23-25 beats per 10 sec interval)
Target heart rate calculations: Percentage of Maximal Heart Rate
APMHR= 220-ageAPMHR x exercise intensity
