Major Principles of Training: Overload Principle - Answer A system does not improve until it is
forced to perform above and beyond the normal/usual daily demands.
Overload can be accomplished by... - Answer increasing intensity, frequency, or duration either
alone or in combinations
Frequency Overload - Answer The more days you exercise per week, the greater the change in
VO2 max. It does level off eventually (there is a limit to what you can reach)
Duration Overload - Answer The longer you work, the greater the adaptation will be. VO2 max
levels off but exercising to lose fat won't)
Major Principles of Training: Specificity of Training - Answer The only system that improves is
the system which is overloaded
Ex: not gonna improve your squat by bench pressing
There is a greater increase in VO2 max when ________ and greater increase in ATP-PC system
when ________ - Answer endurance training; sprint training
CV System is being trained no matter what activity you're doing
Major Principles of Training: Heredity - Answer The success of a training program is limited by
genetic endowment
e.g. body type, gender, initial system levels, adaptation capacity, adaptation rate, etc.
Factors affecting Performanc - Answer Diet, CNS Function, Strength/Skill, Environment, Energy
Production
,increases both hypertrophy and hyperplasia
Training Considerations: Metabolic Systems - Answer Desired result is to reduce rate of fatigue
(increased rate of ATP re synthesis)
1. Increased number of metabolic system enzymes
2. Increased availability of energy substrates
3. Increased removal of metabolic by-products
needs helps from improved cardio-respiratory system
Training Considerations: Cardio-Respiratory Systems - Answer Desired result is to promote
delivery and removal system (note: if one improves VO2 max this result will occur)
1. Increase stroke volume
2. Alter blood factors
3. Increase A-V O2 difference (need to improve metabolic systems)
Biochemical changes in Skeletal Muscle following Metabolic Specific Training: Immediate System
(1st of 3) - Answer 1. Increase in muscular stores of ATP and CP
25% increase in ATP amount and 40% increase in Creatine Phosphate amount
Biochemical changes in Skeletal Muscle following Metabolic Specific Training: Immediate System
(2nd of 3) - Answer 2. increased concentration and activity of system enzymes (e.g. CPK & MK)
Usually increase in both enzymes and substrates cause if you increase enzymes but not
substrate you will run out twice as soon
MK takes two ADPs to make ATP (matches increase in ATP)
CPK matches Creatine Phosphate increases

, Biochemical changes in Skeletal Muscle following Metabolic Specific Training: Glycolytic System
(1st of 3) - Answer 1. Increased glycogen storage (>2x)
After 20 weeks of intense training, double amount of glycogen stores
Biochemical changes in Skeletal Muscle following Metabolic Specific Training: Glycolytic System
(2nd of 3) - Answer 2. Increased concentration and activity of glycolytic enzymes
PFK doubles with increased glycogen, HK doesn't cause its used anytime glucose enters cells
HK doesn't increase as much as PFK cause it is used mored and PFK is only used in Glycolytic
System which is further down the chain (after immediate)
Why can't you do more than double your glycolytic capacity? - Answer It requires space and
space is limited
Biochemical changes in Skeletal Muscle following Metabolic Specific Training: Glycolytic System
(3rd of 3) - Answer 3. Increased concentration and activity of gluconeogenic enzymes
increased conversion into glucose
Biochemical changes in Skeletal Muscle following Metabolic Specific Training: Oxidative System (
1st, 2nd of 12) - Answer 1. Increased glycogen storage (150%)
2. Increased muscular stores of triglycerides (about 140%)
Biochemical changes in Skeletal Muscle following Metabolic Specific Training: Oxidative System
(3,4,5 of 12) - Answer 3. Increased myoglobin (80%)
4. Increased concentration and activity of pyruvate handling enzymes (doubles)
5. Increased concentration and activity of beta-nidation enzymes (doubles_
Doubling oxidative system needs twice as much oxygen and twice as many oxygen carriers
(myoglobin)
