Definitions Flashcards
What is VO2?
The highest rate at which energy is provided via aerobic metabolism
What is oxygen uptake?
The volume of oxygen used under given conditions eg at rest, during submax, during max
Maximal exercise. What is it
When an individual is working at their exercise capacity - highest level of physical exertion that can be sustained ⏫
What is the anaerobic threshold?
The physiological exertion level between aerobic and anaerobic metabolism - where lactate production exceeds removal 📈
Ventilatory threshold?
The point where pulmonary ventilation increases disproportionately relative to increases in O2 consumption during graded exercise 😅
OBLA is..
The onset of blood lactate accumulation. Point during exercise at which lactic acid builds up in the blood, and fatigue sets in 😴 hitting the wall!
Continuous vs interval
- Continuous exercise without rest 🔛
2. Interval is alternating periods of exercise and rest ⏳
Fartlek vs circuit
- ‘Speed play’, alternating speeds of fast and slow 🏃🏼♀️
2. Circuit is alternating modes of aerobic and resistance exercise 🏋🏼♀️
What is running speed?
The interaction of stride frequency 🔢 and stride length ⛸
What is agility defined as..
Ability to change directions and movements at high velocities
What is speed..
Skills and abilities needed to achieve high movement velocities
Speed endurance is..
The ability to maintain maximal movement velocities or repeatedly achieve maximal accelerations and velocities.
Plyometrics is..
Explosive movements that increase the elasticity of muscles, ligaments and joints.
What are the 5 principles of training? RRISO
Overload Specificity Individuality Recovery Reversibility
Eccentric movements
Lengthening, stretch. Opening a bicep curl
Concentric movements
Flex 💪🏼💪🏼💪🏼 shortening, eg bicep curl
Isometric movements
Static, no movement 👀
Contraindications to exercise
Dizziness
Unusual fatigue
Intermittent classification
