  1. ACHPER NSW PDHPE HSC Enrichment Day 2009 Core 2 Factors Affecting Performance

  2. Factors Affecting Performance Overview How does training affect performance? • energy systems • types of training How can nutrition affect performance? • balanced diet • guidelines for fluid replacement

  3. Energy and physical activity • Energy is the capacity to do work. • In the human body the transformation of of energy within the body from chemical or potential energy (food) to mechanical or kinetic energy (movement) is of most importance.

  4. Production of energy in the body How much ATP can be stored in a cell? energy for muscle movement ATP A P P P Bond broken by an enzyme Energy released for movement and heat ADP is produced More ATP is required A P P P

  5. Resynthesis (recycling) • Only a small amount of ATP can be stored • Phosphate used to rebuild ATP • Three methods of resynthesis All 3 depend on: Time and Intensity 2 occur rapidly (anaerobically) 1 occurs as oxygen reaches the cells (aerobically)

  6. Energy Systems

  7. Tour de France • A road cycling race of 21 stages over a total distance of 3,500 kilometres • 10 flat stages, 5 mountain stages, 4 medium mountain stages, 2 individual time-trial stages and 2 rest days • 4 mountain finishes

  8. The use of energy systems in the Tour de France

  9. Preparing the Tour de France Athlete • Road cycling primarily requires strength and endurance although anaerobic capacity may be called upon in break away, hill climbs and all-out sprints to the finish. • At the elite level, training involves at least daily sessions, with weekly distances tallying 400-1000kms. The majority of this training would be continuous, fartlek and long interval training. Weight training may also be included, with flexibility training used to prevent injury.

  10. Continuous: road rides, rollers, stationary trainer and ergonometer Fartlek: undulating courses, intermittent sprints and pack riding Interval: track work, rollers, stationary trainer and ergonometer Circuit: predominantly general aerobic activities May be done as a circuit Focus on strength endurance 15RM+ Medium speed 3-6 sets Minimal rest Focusing predominantly lower body and core stability Training the Tour de France Athlete Aerobic Training Resistance Training

  11. Feeding the Tour de France Athlete • Elite cyclist aim for low body fat levels to keep the power to weight ratio high in particular for hill climbs, a feature of the Tour de France race. • Long kilometres and hours of training and racing call for a high energy diet rich in protein, vitamins, minerals and carbohydrates. • Elite male cyclist may consume 26,000 kilojoules per day. This involves frequent meals and snacks. • Hydration and carbohydrate replenishment are crucial to success and safety.

  13. A Tour de France cyclist needs to feel like the penguin not the polar beer each morning..
