Energy Systems• Back Position = Mainly high-intensity

• Creatine Phosphate• Used during tackling and sprinting,

passing, and jumping• Lasts 5-10 seconds• Creatine stores can be maintained by

consuming animal sourced foods(Doyle, Dunford, 2012)

http://www.brianmac.co.uk/energy.htm

• Anaerobic Glycolysis• Main energy system used due to the

“stop and go” of the sport• Used for sprints, or repeated high

intensity sprints of the game• Lasts for as long 2 minutes• Can be maintained with adequate

amount of CHO consumed(Holway, Spriet, 2011)

(Doyle, Dunford, 2012)

Energy Systems

http://www.brianmac.co.uk/energy.htm

• Oxidative Phosphorylation• Is aerobic (uses oxygen)• Used after 2 minutes• Within the sport, used when she is

standing, walking, jogging and running for long periods of time

• Uses fat as the main source of energy

Energy Systems

Training Regime• 6 days/week• 2 hours/day• Mostly endurance training during practices with some aspects of

strength required• Does her own resistance training (1/4 of the time/day)• No specific nutrition plan followed to support training:• Eats healthy and stay hydrated• Does not eat heavy before training/game but instead eats after (usually

high in CHO)

• Nutrients that performance is best dependent on• Water• Low glycemic index CHO

Practical Issues that a Rugby Player Faces

• Hydration during the event• Unless multiple subs, hydration can only occur when a try

occurs• Important to avoid dehydration which can negatively affect

performance

• CHO intake during the event• Again, unless multiple subs CHO intake during a game is

difficult• Important for the delay of fatigue

• Nerves before the game• Can affect GI

Overcoming Practical Issues

• Utilize the rest period • Utilize subs• After scoring a try, consume Gatorade instead of just

plain water

Conclusion

• Based on the one day analysis:• Athlete was not consuming enough CHO before, during and

after the event• Athlete was consuming enough PRO after the event• Athlete was not consuming water during and after the event
