Chapter 4: Understanding the Spectrum of Athletes and Performance Flashcards
(18 cards)
developmental stage
youth vs adult - one of the ways SNCs can distinguish/decide where on the spectrum their clients can call
What are 3 different ways SNCs can differentiate where the clients fall on the spectrum?
- sporting type
- developmental stage
- competition level
ventilatory & lactate threshold
a point during exercise in which breathing and lactate get build up quick in our bodies (when we feel fatigue the most)
energy systems
mechanisms in which body produces energy
heart rate variability
the variance of the duration between heart beats
hydration status
the status of water balance in body
BMR - Basal Metabolic Rate
caloric expenditure when body is at rest (people in their adolescent years have higher BMR 10 - 19) since they need the energy to operate their normal body parts and more active throughout the day
General Nutrition Recs for Youth Athletes
Protein percentage
Fat Percentage
Carb Percentage
Protein (15-20% of total calories) 0.8 - 1.2 g/kg
Fat (15% - 30% of total calories)
Carbs (less than 50% of total calories) : 3-8g/kg
How much protein is recommended/needed after exercise?
0,4grams/kg x 3 or 4 through out the day
Anaerobic
without oxygen (weightlifting, sprinting)
Phosphagen System
is a form of anaerobic metabolism. It is the quickest and the most powerful energy source for muscle movement (only about - 10 seconds)
Phosphagen system uses creatine phosphate to create ATP (adenosine triphosphate, which is the chemical used to create all energy and fuels body/muscle movement)
Glycolytic System
is a form of anaerobic metabolism that involves breakdown of glucose to create ATP. it provides energy for - 90 seconds of high intensity exercise
Aerobic
with oxygen (Example can be jogging, dancing, hiking)
Substrate utilization
how certain substance is used up during metabolism - for example how fat and carbs are used up to expend energy during exercise
**represents the contribution of fat and carbohydrates to energy expenditure during exercise
Krab Cycle & electron transport chains
both are part of aerobic systems to create ATP during longer duration, lower intensive exercises
Endurance exercises - marathons
needing aerobic, slow glycolysis fatty acid oxidation but also may include short bursts of energy that require glycolytic and phosphagen energy systems for energy production
They typical require more protein than general public but less than strength biased athletes
Strength biased exercises - powerlifting/weightlifting
needing quick bursts of energy (-10 seconds) getting ATP from creatine phosphate - aerobic
Youths & Adolescents athletes
There’s some evidence that they require more energy surplus - substrate oxidation is different with them than adults. They rely heavily on fat oxidation and have lower ability to use glycogen for energy production than adults.
**adolescents, unlike adults, tend to use less glucose and slightly more fat as fuel during exercise.
