Lecture 4 Flashcards
What are the three planes of motion, and what types of motion does each include?
sagital: flexion and extension
frontal (coronal): adduction and abduction
transverse (horizontal): rotational
what are three energy systems
ATP PCr system, anaerobic glycolysis, aerobic glycolysis
ATP PCr system
energy system that uses phosphate in phophocreatine to create ATP
- doesn’t use oxygen
- lasts 5-10 seconds
- high-intensity work like sprints
anaerobic glycolysis
use of glucose and breakdown of glycogen to create ATP
-doesnt use oxygen
- lasts 10 sec - 2 min
- ex 200 yard dash
- byproduct is lactic acid
Aerobic glycolysis
use of fat, protein, carbohydrates to create ATP
- w/ oxygen
- fat and carbs are primary energy source
- used during prolonged exercise
- lasts 2 min
how does lifting affect the body?
- glycogen stores are depleted from anaerobic glycolysis
- microtears in muscles
what to eat after a lift
protein and carbs within 30 mins of finishing an exercise
what happens to insulin after a workout
insulin response from depletion of glycogen, results in a spike in insulin and shuttles glucose to muscles along with amino acids to rebuild microtears
how much protein and carbs should be consumed after a workout?
0.3 g/kg of protein and 1-1.2 g/kg of carbs
recommendations for protein consumption in sedentary adults
0.8 g/kg of protein/day
recommended protein and carb consumption in active adults/atheltes
1.2-2.0 g/kg of protein a day and 6-10 g/kg of carbs per day
what does pre-workout containing caffeine do to the body
stimulates the central nervous system, can improve response time, decrease fatigue, and increase alertness
recommended caffeine intake by the FDA
less than or equal to 400 mg/day
- the body begins to adapt to dosages so higher dosages are needed for the same benefits/effects
what is creatine monohydrate
shown to increase stregnth and muscle mass, increase body’s stores of phosphocreatine thus making more ATP
what is the dosage of creatine?
the loading phase is recomened at 20 g/day for 5-7 days with maintenance of 3-5 g/day
