Q

What is the difference between validity and reliability?

A

Validity refers to a test’s ability to measure what it is meant to assess.

Reliability refers to the ability of a test to reproduce similar results when conducted in similar situations and conditions.

17
Q

What is supplementation?

A

Any addition to an athlete’s regular diet that aims to achieve a particular nutritional goal.

18
Q

What are the 4 forms of supplementation?

A
  • Vitamins/minerals.
  • Protein.
  • Caffeine.
  • Creatine products.
19
Q

What are vitamins? What are minerals?

A

Vitamins are organic substances that assist the body’s use of energy.

Minerals are inorganic substances crucial to upholding bodily function.

20
Q

What are the advantages of vitamin supplementation?

A
  • Very important in energy metabolism and haemoglobin synthesis.
  • Supports lean body mass.
21
Q

What are the disadvantages of vitamin supplementation?

A

Excess consumption is very bad.
- Some vitamins are fat soluble and hence toxic in excess consumption.
- Headaches, muscle and joint pain.
- Urinated out, causing dehydration.

22
Q

What are the advantages of iron supplementation?

A
  • Assists in oxygen transportation (haemoglobin and myoglobin).

Very good for endurance athletes.

23
Q

What are the disadvantages of iron supplementation?

A
  • May cause gastrointestinal problems during performance.
24
Q

What are the advantages of calcium supplementation?

A
  • Improves bone density.
25
Q

What are the disadvantages of calcium supplementation?

A
  • Increased risk of kidney stones.
  • Can interfere with meds.
26
Q

What are the advantages of caffeine supplementation?

A
  • Promotes utilisation of fats as a source of fuel, sparing the use of glycogen stores in muscles.
  • Increases alertness and awareness.
  • Changed perceptions of fatigue.
27
Q

What are the disadvantages of caffeine supplementation?

A
  • Has a diuretic effect in caffeine drinks.
  • Causes impairment of fine motor skills.
  • Over-arousal.
  • Excessive amounts can lead to faster heart rate, urination, nausea, tremors, anxiety.
28
Q

What are the advantages of protein supplementation?

A
  • Assists in the repair and recovery of muscles.
29
Q

What are the disadvantages of protein supplementation?

A
  • Can’t be stored like carbs - will interfere with kidney function.
  • Decreases other vitamin and mineral intake.
30
Q

What are the advantages of creatine supplementation?

A
  • Accelerates gains in muscle size and strength.
  • 5-8% uptake in anaerobic capacity.
  • Prior creatine loading enhances glycogen storage and carb loading in trained muscles.
31
Q

What are the disadvantages of creatine supplementation?

A
  • Transient increase in body weight in the loading phase due to bloating.
  • May be more susceptible to cramps and spasms.
  • Athletes need to drink more water due to water retention.
32
Q

What are the pre-performance nutritional considerations for an aerobic athlete?

A

4-5 days prior they should taper and carb load 7-12g each meal.

The day prior they should consume 4-5L of water.

3-4hrs before eat a mix of simple and complex carbs.

1-2hrs before they should eat high-GI food + 600mL approx of water.

15-20min prior they should drink 150-200mL water and carb gels for simple carbs.

As they approach the event, size of carb intake should become smaller and smaller

They should not try new foods.

33
Q

What are the pre-performance nutritional considerations for an anaerobic athlete?

A

They don’t need heavy alterations to diet, as ATP stores exist and replenish naturally and in time.

They should consume tiny bit of simple carbs before the event and sip some water so they stay hydrated and coordination is not impaired, and so muscles do not get injured - generate power.

34
Q

What are the during performance nutritional considerations of an aerobic athlete?

A

Every 15-20min they should drink 150-200mL of sports drink to replenish electrolytes and hydration.

Eat carb gels intermittently to replenish simple carbs during performance.

35
Q

What are the during performance nutritional considerations of an anaerobic athlete?

A

Just like aerobic, they should stay hydrated.

Sip water to maintain healthy movement.

36
Q

What are the post-performance nutritional considerations for an aerobic athlete?

A

Within the 1st hour consume 50-100g high-GI food to instantly replenish lost energy and get back to pre-performance state.

Next hour, they should consume 50-100g complex carbs. Repeat every hour until 500-600g are consumed.

3:1 ratio of carbs to protein applies. Eat 50-100g protein to repair microtears in muscles.

Drink 1.5L for every kg of bodyweight lost through sweat. Can include sports drinks.

37
Q

What are the post-performance nutritional considerations for an anaerobic athlete?

A

Drink water, eat high-GI foods to replenish energy.

Higher protein intake than aerobic as more muscle microtears occur.

38
Q

What should both anaerobic and aerobic athletes avoid with nutritional considerations?

A

Avoid diuretics as they lead to dehydration and reduces ability to thermoregulate.

High-fibre food before performance as they make it easier to excrete.

New foods - athletes may have a negative reaction.
