Core 2: Critical Q3 Flashcards
How can nutrition and recovery strategies affect performance? (49 cards)
What does our body require?
Our bodies require the right ratio of nutrients to function effectively
What are macronutrients?
- Carbohydrates
- Proteins
- Fats
What are carbohydrates?
Provide substantial energy for movement
- Simple (sugar)
- Complex (Starch and fibre)
What are proteins?
Assist in growth and development and repair muscle damage after exercise
What are fats?
Provide energy, warm the body and insulate organs
What are micronutrients?
- Vitamins
- Minerals
What is the significance of vitamins for performance?
Assist in bone, teeth and tissue growth
What is the significance of minerals for performance?
Keeps tissues healthy and are required for chemical reactions
What is the significance of water for performance?
- Hydration is an essential part of a balanced diet
- Chemical reactions, maintain bodily functions, remove waste and perspiration
What is the aim of Pre-performance nutrition and hydration?
To provide adequate energy and optimal hydration for the performance ahead
What is a pre-performance meal plan for nutrition
- 3 hours before complex carbohydrates (Slow release allows for continual energy supply)
- 1-3 hours before avoid large meals and consume snacks
- 1 hr before simple carbohydrate snacks
What is a pre-performance meal plan for hydration for an endurance athlete?
- 24 hours increase regular fluid intake
- 2-3 hours 500ml of water
- 15 mins before 200ml of water
What are some further considerations for pre-performance on nutrition and hydration?
- Maintain a balanced meal
- Consume easily digestible foods
- Consume familiar foods
- Don’t eat immediately before an event
- Longer events = more carbs and hydration
What is carbohydrate loading?
Loading muscles with glycogen and tapering training in the 2-3 days before an event
What nutrition are required by power-based athletes before performance?
Eat some protein 1 hour before
What is the aim of during-performance nutrition?
To maintain endurance and delay the onset of fatigue
What are the strategies for endurance athletes during performance?
- Simple carbohydrates snacks (Sports gels: highly concentrated, easily consumed and digested quickly)
- 200-300 ml of sports drink every 15 minute
What are the strategies for power-based athletes during performance?
- Simple carbohydrates snacks (Sports gels: highly concentrated, easily consumed and digested quickly)
- 200-300ml of water every 15 minute
What are the further considerations for nutrition and hydration during performance?
- Strategies which work for one athlete may not work for another
- Athlete should only consume foods they are familiar with - Avoid trying new supplements on day of event
- Some athletes lose more fluids during performance than others - Replace a practical amount of fluids
What is the aim of post-performance nutrition and hydration
To return the body to pre-performance state as quickly as possible
What are the 3 Rs of recovery?
- Refuel glycogen stores
- Repair muscle damage (Physical activity causes microtrauma)
- Rehydrate after fluid loss (If not, athletes may experience dehydration, heat stroke & prolonged heat exhaustion)
What are the post-performance strategies for power-based athletes?
- <1 hour after -> 1g of simple, high GI carbohydrates per kg of body weight
- <1 hour protein powder shake
What are the post-performance strategies for endurance athletes?
- <1 hour after -> 1g of simple, high GI carbohydrates per kg of body weight
- 1-6 hours 1g of carbs per kg of weight, integrating complex carbs over time
- 4-6 hours 1.5 L of fluid per kg of weight lost during activity
Why are performance enhancing substances used?
Have the potential to improve energy systems or eliminate energy constraints, but also each have potential health effects
