ch. 21 Flashcards
Overtraining
accumulation of training stress that impairs an athlete’s ability to perform training sessions and results in long term decrements of performance
Overreaching
excessive training that leads to short term decrement in performance with adequate rest intervals between training sessions
- (lead to improved performance)
Within how many weeks after cessation of training can reduce Vo2 Max
2 weeks
What is one of the most important influences that contribute to the observed individual variations in training response?
athletes beginning level of fitness
Training an only improve anaerobic performance to a small degree because
- type of skeletal muscle fiber that is best suited for anaerobic performance (type IIx) is determined early in development
What are the general objective sport conditioning
improve performance by increasing muscle force/power output, improving muscular efficiency, and improving muscle endurance
every training session should consist of 3 components:
- warm up
- workout
- cool down
2 objective of warm up
- warm up increases cardiac output and blood flow to skeletal muscles to be used during session
- warm up activity results in muscle temperature which elevates muscle enzyme activity
length of warm up
10-20 min
objective of cool down
- return pooled blood from the exercised skeletal muscles back to the central circulation ,
Benefit or warm up
- feasible that a warm up reduces the risk of muscle and or tendon injury during exercise
Three principal aerobic training methods used by athletes
- interval training
- long, slow distance (low intensity)
- high intensity continuous exercise
what are the variables related to endurance
- improvement of VO2 max
- increase lactate threshold
- improve running economy
The intensity and length of the work interval depends on
what athlete is trying to accomplish
Interval training that is designed to improve VO2 max typically involves intervals longer than
50-60 seconds to increase involvement of aerobic ATP production
high intensity intervals are more effective in improving aerobic power because of
recruitment of fast twitch fibers during this type of exercise
High intensity interval training (HIIT)
describe high intensity intervals lasting 30-120 seconds
- HIIT promotes improvements in aerobic capacity
advantage of interval training over continous running at slower speeds is that
this method of training provides a means of performing large amounts of high intensity exercise in a short time
advantage of interval training over continous running at slower speeds is that
this method of training provides a means of performing large amounts of high intensity exercise in a short time
interval training offers two ways of providing a training overload
interval training can be modified to provide overload in terms of increasing either total number of exercise intervals performed or the intensity of the work interval
When planning an interval training session:
- length of the work interval
- intensity of the effort
- duration of the rest interval
- number of interval sets
- number of work repetitions
What should exercise HR reach during interval training?
85-100% of maximal HR during interval training
rest interval
- time between work efforts which consists of light activity such as walking
length of rest interval is expressed as a ratio of
ratio of the duration of the work interval
For athletes who are not already highly trained, a work:rest ratio of
1:3 or 1:2 may be preferable
set
specified number of work efforts performed as a unit
repetition
number of work efforts within one set
long slow distance exercises involves performing exercise at
low intensity (50-60%) for durations that are generally greater in length than the normal competition distance
historical reason that athletes have used training sessions of long endurance is belief that
improvementsin endurane are proportional to the volume of training performed
What percent intensity is considered optimal
80-100 VO2 max
What work rate provides improvement in maximum aerobic power
work rate that is equal or slightly above the lactate threshold
Benefit of using Measurement of exercise heart rate can be used as an estimate of an athletes relative training intensity
simplicity because athletes can esaily measure their heart rates during exerise using electronic heart rate monitors
Live-High Train Low
training program requires the athlete to spend most of the day resting and sleeping at altitude, but the athlete performs exercise training session at much lower altitudes
Benefit of Live high, train low program?
affords the athlete the benefit of altitude acclimatization, and by training at a low altitude, the athlete’s ability to perform intense training is not hampered by high altitude
training to improve maximal aerobic power has 3 methods
- interval training
- long slow distance exercise
- high intensity continuous exercise
What is the most important factor in improving vo2 Max
intensity and not duration
