ADAPTATIONS TO AEROBIC ENDURANCE TRAINING PROGRAMS
WHAT ARE THE CARDIOVASCULAR EFFECTS OF ACUTE AEROBIC EXERCISE?
- INCREASED CARDIAC OUTPUT
- INCREASED STROKE VOLUME
- INCREASED HEART RATE
- INCREASED O2 UPTAKE
- INCREASED SYSTOLIC BP
- INCREASED BLOOD FLOW TO SKELETAL M
- DECREASED DIASTOLIC BP
WHAT ARE THE RESPIRATORY RESPONSES TO AEROBIC EXERCISE?
- INCREASED O2 UPTAKE
- INCREASED O2 DELIVERY TO TISSUES
- INCREASE CO2 DELIVERED TO LUNGS
- INCREASED MINUTE VENTILATION
WHAT IS THE IMPACT OF AEROBIC ENDURANCE TRAINING ON CAPILLARY DENSITY
INCREASED CAPILLARY DENSITY
WHAT IS THE IMPACT OF AEROBIC ENDURANCE TRAINING ON ENZYME ACTIVITY?
- INCREASED CREATINE PHOSPHOKINASE ACTIVITY
- INCREASED MYOKINASE ACTIVITY
WHAT IS THE IMPACT OF AEROBIC ENDURANCE TRAINING ON METABOLIC ENERGY STORES?
- INCREASED STORED ATP
- INCREASED STORED CP
- INCREASED STORED GLYCOGEN
- INCREASED STORED TRIGLYCERIDES
WHAT IS THE MOST SIGNIFICANT CARDIOVASCULAR ADAPTATION WITH LONG TERM AEROBIC ENDURANCE TRAINING?
INCREASED MAX CARDIAC OUTPUT
WHAT NERVOUS SYSTEM ADAPTATIONS OCCUR WITH AEROBIC ENDURANCE TRAINING?
- INCREASED EFFICIENCY
- DELAYED FATIGUE OF CONTRACTILE MECHANISMS
MOST ADAPTATIONS IN MAXIMAL OXYGEN CONSUMPTION CAN BE ACHIEVED IN WHAT TIME PERIOD?
6-12 MONTHS
WHAT IS ONE OF THE MOST IMPORTANT FACTORS IN IMPROVING AND MAINTAINING AEROBIC POWER?
INTENSITY OF TRAINING
WHAT TYPE OF INTERVAL WORKOUT IS BEST FOR IMPROVING MAXIMAL OXYGEN UPTAKE?
SHORT HIGH INTENSITY BOUTS OF SPRINTS WITH SHORT INTERIM REST PERIODS
WHAT ARE TWO ADAPTATIONS THAT OCCUR EARLY ON IN ACCLIMATIZATION TO HIGH ALTITUDE?
- INCREASE IN PULMONARY VENTILATION (HYPERVENTILATION)
- INCREASE IN CARDIAC OUTPUT (SECONDARY TO INCREASED HEART RATE)
AFTER HOW MANY DAYS AT ALTITUDE DO HEART RATE AND CARDIAC OUTPUT BEGIN TO RETURN TO NORMAL LEVELS?
10-14 DAYS
WHY DO HEART RATE AND CARDIAC OUTPUT BEGIN TO RETURN TO NORMAL LEVELS AFTER 10-14 DAYS AT A GIVEN ALTITUDE?
INCREASED RED BLOOD CELL PRODUCTION
WHAT ARE THE CHRONIC PHYSIOLOGICAL AND METABOLIC ADJUSTMENTS THAT OCCUR DURING PROLONGED ALTITUDE EXPOSURE?
- INCREASED HEMOGLOBIN AND RED BLOOD CELL PRODUCTION
- INCREASED DIFFUSING CAPACITY OF OXYGEN THROUGH PULMONARY MEMBRANES
- INCREASED CAPILLARIZATION
- MAINTENANCE OF ACID-BASE BALANCE OF BODY FLUIDS THROUGH HYPERVENTILATION AND RENAL EXCRETION OF HCO3
WHAT IS THE MINIMUM DURATION NEEDED FOR AN ATHLETE TO ADAPT IN MODERATE ALTITUDE?
3-6 WEEKS
