Chapter 4 Flashcards
10 Principles of Conditioning
- Safety
- Warmup/cooldown
- Motivation
- Overload
- Consistency
- Progression
- Intensity
- Specificity
- Individuality
- Minimal Stress
4 Considerations for continuous training
- Frequency of Activity
- Intensity of Activity
- Type of Activity
- Time of Activity
4 things transportation of oxygen throughout the body involves
- heart
- lungs
- blood vessels
- Blood
Agonist Muscle
Muscle contracting to produce movement
Antagonist Muscle
muscle being stretched in response to contraction of the agonist muscle
ATP
immediate energy source
Ballistic Stretching
bouncing movement, repetitive contractions of the agonist muscles are used to produce quick stretches of the antagonist muscle
Concentric Contraction
muscle shortens in length as a contraction is developed to overcome or move some resistance
(Dynamic)
Dynamic Stretching
Recommended prior to activity
Eccentric Contraction
Resistance is greater then the muscular force being produced, muscle lengthens while continuing to contract
(Dynamic)
Endurance Training
lighter weights, higher reps
Fast Twitch Fibers (aka Type II)
capable of producing quick, forceful contractions but have a tendency to fatigue more rapidly than ST fibers
—> short term, high intensity, anaerobic type activities
Isokinetic Exercise
length of muscle changing while contraction performed at a constant velocity
- biodex is only available isokinetic device
Isometric Contraction
muscle contracts to increase tension but there is no change in the length of a muscle
Isotonic Contraction
may be concentric or eccentric
Example - biceps curl with bicep contraction on elbow flexion and extension
flexion - biceps contracts and shortens - concentric
extension - biceps controlling weight back down - eccentric
normal maximum aerobic capacity for the most college-aged athletes?
45-60ml/kg/min
Plyometric Exercise
A rapid stretch of a muscle eccentrically, followed by a rapid concentric to produce a forceful, explosive movement in a short period of time
*place a great deal of stress on MSK system
Slow Twitch Fibers (aka Type I)
dense with capillaries and are in rich mitochondria and myoglobin, giving the muscle tissue its characteristic red colour
—> carry more oxygen and are more resistant to fatigue than fast-twitch
—> long duration, aerobic activities
Static Stretching
passively stretching a given antagonist muscle by placing it in a maximal position of stretch and holding it there for an extended period of time
Strength training
heavier weights with a lower number of reps
three factors determining the maximal rate at which oxygen can be used
- External respiration
- ventilatory process or pulmonary function
- Gas transport
- accomplished by the cardiovascular system
- Internal respiration
- use of oxygen by the cells to produce energy
Three Phases of of Preparatory Period
- Hypertrophy/Endurance Phase
- Strength Phase
- Power Phase
What is a Macrocycle?
Complete training period
- intensity, volume and specificity of conditioning are altered to achieve peak levels of fitness
What is a Mesocycle?
a series of mesocycles within a macrocycle
- may last for several weeks or even months
