DESCRIPTION

This is an introduction to the H3.7 Unit at Boort Secondary College. It also covers the initial part of the first unit on sports nutrition

TRANSCRIPT

  • 1.H3.7 Physical Education Unit Introduction

2. What Will We Be Learning

  • Sports Nutrition
  • Sports Coaching
  • Biomechanics
  • Sports Injuries
  • Patterns of Participation & Motivation for sports

3. Practical Classes

  • Prac Classes will be held each Friday Periods 4 and 5 unless otherwise mentioned
  • You are required to bring all necessary gear

4. What Types of Sports?

  • We will aim to participate in a variety of Sports For Life
  • These include sports such as

5. SPORTS NUTRITION 6. IS BASED UPON

  • The basic principles that govern general nutrition
  • That is, a balance of all nutrients, a variety of food and moderation of the intake of that food.
  • With that in mind, the importance of the training diet has been recognised.

7. THE TRAINING DIET..

  • Athletes now understand that they must eat well to ensure maximum return from heavy training schedules.
  • The competition diet is established providing athletes with knowledge of special eating practices, before, during and after the event to maximise their performance.

8.

  • Each sports person will have different dietary requirements depending on
  • Training
  • Age
  • Sex
  • Body size
  • Sport played
  • Environment for training and competition

9. GENERAL PRINCIPLES OF SPORTS NUTRITION

  • Recommended balanced diet for average sports person is.
  • 55 60% Carbohydrates
  • 25 30% Fats
  • 10 15% Protein
  • Recommended balanced diet for more strenuous athlete is
  • 70% carbohydrates
  • 15 20% Fats
  • 10 15% Protein

10. GUIDELINES FOR ASPORTS PERSON DIET

  • Increase complex carbohydrates
  • Decrease dietary fat
  • Ensure adequate protein intake
  • Increase dietary fibre
  • Decrease/eliminate alcohol
  • Decrease salt intake
  • Increase water intake

11. COMPETITION DIET

  • It is important to understand nutritionally related factors that cause fatigue & reduced performance.
  • These being : - depletion of muscle stores&dehydration

12. STRATEGIES TO REDUCE, DELAY OR OFFSET THESE FACTORS

  • General preparation of energy stores
  • (increase carbohydrate intake to ensure natural storage capacity)
  • Carbohydrate loading for endurance events
  • (gradually reduce training early in the week, maintain normal diet to maintain carb levels reduce training further and consume high level of carbohydrates
  • 80 85% of kj intake)
  • Pre-competition meal
  • (ensure that glycogen stores are topped up for strenuous exercise, adequate hydration)

13. STRATEGIES CONT..

  • Carbohydrate supplementation (marathons)
  • (generally in fluid form in small amounts and frequent intervals this maintains blood glucose levels and spares muscle glycogen)
  • Glycogen replenishment
  • (first 15 min after exercise eat foods high in glycogen eg fresh fruit, lollies..
  • Following two hours meal high in complex carbs & protein
  • Fluid replenishment
  • Before, during and after

14.

  • CARBOHYDRATES

STARCH SUGARS BREADS, CEREALS, RICE, PASTA AND POTATO TABLE SUGAR, HONEY, FRUIT SUGAR, LOLLIES, SOFT DRINK AND BEER 15.

  • CARBOHYDRATES

COMPLEX (contain other useful nutrients) Preferred option for carb intake due to being an efficient energy source, readily used. Stores depleted quickly so need to be replaced frequently SIMPLE Carbohydrates stored as GLYCOGEN in the muscles and liver. Muscles cannot perform without it. Therefore need to be replenished 16. QUESTIONS.

  • What factors affect the dietary requirements of a sports person?
  • What is the difference between the average athletes intake of carbs, protein & fat and that of an athlete of strenuous activity?
  • List the guidelines for a sportspersons diet?
  • Explain the role of the pre competition meal and carbohydrate loading?
  • List some main sources of complex carbohydrates.

  • Working in Groups of 2 or 3 you are to create a poster detailing the suggestions of healthy eating
  • Posters will be a reference guide for future activities
