Exam 3- Lecture 15 Flashcards
What is the “training effect?”
The gradual adaptation of the tissue or system to overload/stress
Is it possible to reach a point where no further physiologic adaptation is possible?
Yes
What is overload/ workload determined by?
- Mode
- Intensity
- Duration
- Frequency
- Rate of Progression
Moderate endurance exercise leads to
- Enhanced mitochondrial capacity
- Little adaptation in glycolytic capacity
Sprint exercise leads to:
- Enhanced glycolytic capacity
(oxidative adaptation is protocol dependent) - Increased capacity for short bursts of high intensity activity
Do VO2max gains achieved through one activity transfer well to others?
No
What can training adaptations be divided into?
- Peripheral (oxidative capacity)
- Central (blood volume, cardia function, hemoglobin concentration)
Explain peripheral adaptations
- highly tasks specific
- only muscles activated in the task will show adaptations to that task
Explain central adaptations
- More readily transfer between activities
- Higher blood volume
- Higher sweat rate
- Ventricular hypertrophy
Cross training potential benefits
- Periods of rest and recovery reduce stress on overworked muscle and connective tissue
- May reduce overuse injury incidence
- Trains accessory tissues to reduce injury reduce injury risk associated with muscle imbalance
- Physiological
Factors that can determine the ability of a healthy individual to respond to training programs?
- Initial fitness
- Genetic factors
- Psychological influences
Exercise prescriptions must account for:
- individual participant’s fitness level
- possibility of adjustment to individual actual response to exercise load
Reversibility principle
Adjustments to exercise training are transient and reversible upon cessation or reduction of training
reduced training for up to how many weeks has no effect of VO2max?
15 weeks
It is inadequate to maintain training effect with fewer than:
2 days/week at <50% VO2max
<10 minutes
