What is the "marker" physiologist measure to see improvement in aerobic training? For anaerobic training?
|
VO2 max; none, so far
|
|
|
How is ANAEROBIC CAPACITY tested?
|
By using the WINGATE TEST to measure the POWER OUTPUT during high intensity exercise over a short 30 second period
(Power output = joules/sec, or Watts) |
|
|
What is the WINGATE TEST PROTOCOL?
|
steps: (for cycle ergometer)
1. accelerate pedaling frequency with zero load to around 100 rpm 2. quickly load 10% of the athletes body mass (i.e., 70 kg = 7 kp load; for non-athletes, use 7.5% body mass) 3. maintain highest pedal frequency possible for 30 seconds 4. calculate Power Output |
4 things
|
|
What is PEAK POWER OUTPUT in the WINGATE TEST EVALUATION? What does it measure?
|
the highest power output of an individual; measured in Watts/kg BW
*it measures the ability of PCr systems to generate ATP* (greater ATP production, the more power one can produce) |
|
|
What is the MINIMAL POWER OUTPUT in the WINGATE TEST EVALUATION?
|
the lowest power output of an individual; measured in Watts/kg BW
|
|
|
What does the MEAN POWER OUTPUT show in the WINGATE TEST EVALUATION?
|
the average power output of an individual over 30 seconds
*It shows the combined ability of PCr and glycolytic system to generate ATP* |
|
|
What does the FATIGUE INDEX show us in the WINGATE TEST EVALUATION?
|
the peak to minimum power output difference divided by time
(peak - min.)/time [measured in Watts/minute] *tells us how well the individual can maintain power output* |
|
|
What are the components of the WINGATE TEST EVALUATION a physiologist must look at in measuring one's anaerobic capacity?
|
1. peak power output
2. minimal power output 3. mean power output for 30 seconds 4. fatigue index |
|
|
What do we want to improve in the WINGATE TEST?
|
1. increased peak power
2. decreased fatigue index *This will show that power is increase and maintained longer. |

|
What are the main things we see with METABOLIC ADAPTATIONS TO ANAEROBIC TRAINING?
|
1. increased ATP-PCr and glycolytic enzymes
2. increased muscle oxidative capacity (for sprints longer than 30 seconds) 3. increased muscle buffering capacity 4. increased muscle strength |
4 things
|
|
What are some ADAPTATIONS to ANAEROBIC exercise?
|
1. Increased ATP-PC and glycolytic enzymes
2. increased muscle oxidative capacity (for sprints longer than 30 sec) 3. increased muscle buffering capacity 4. increased muscle strength |
4 things
|
|
Comparing aerobically trained athletes to anaerobically trained athletes, what is a large contributing factor to overall improvement of INDIVIDUAL types?
|
ENZYMES; aerobically trained athletes have increase aerobic enzymes, while anaerobically trained athletes have increased anaerobic enzymes.
|
|
|
Comparing aerobically trained athletes to anaerobically trained athletes, what is a large contributing factor to overall improvement of BOTH types?
|
POWER OUTPUT increases in both types of trained athletes.
|
|
|
Performance improvements after ANAEROBIC training (short, high-intensity training) appear to be related more to __________ than _______.
|
muscular strength gains; improvement in the anaerobic yield of ATP through the ATP-PC and glycolytic systems
|
|
|
ANAEROBIC training improves ________ but does little to ______.
|
muscle buffering capacity; increase the muscles' capacity to tolerate sprint-type activities.
|
|
|
What does improved muscle BUFFERING capacity allow?
|
allows sprint-trained athletes to generate energy for longer periods before fatigue limits the contractile process
|
|
|
What are the IMPORTANT ADAPTATIONS to ANAEROBIC training?
|
from greatest to least importance:
1. increased muscular strength 2. increased muscle buffering capacity 3. increased glycolytic enzymes |
