Introduction Athlete Information Needs Analysis Testing Results Interventions
Overview
Performance dictated by several variables◦ Running Economy
VO2 Kinetics Lactate Threshold Muscle Fibre Distribution
◦ Psychology Self Talk Goal Setting Imagery
◦ Nutritional Status Hydration Levels Muscle Glycogen Fuel Utilization (Billat et al., 2004)
Introduction
10 k: 42:48 Half marathon: 1.38
Goals working towards: A 10k personal best time at the end of April Would like to run a full marathon in the next
year
Current Personal Bests....
Needs Analysis
Running Economy◦ Improved running economy refers to O2 cost of
running for a given velocity or the volume of O2 consumed per distance.
VO2MAX◦ Greater levels of VO2max will provide improved
O2 delivery to working muscles.◦ This will decrease levels of fatigue in working
muscles
(Billat et al., 2004)
Aerobic Capacity
Lactic acid is a waste product of distance running.
Levels of blood lactate rise as intensity of run increases.
Build up of hydrogen ions will cause muscular short term fatigue decreasing running velocity.
Lactic Acid can be trained, so that lactate threshold occurs at greater running velocities.
Lactate shuttle hypothesis (Brooks, 1998)
(Gladden, 2008)
Lactic Acid System
Performance Profiling ◦ Indicate what athlete believes to be important
variables to success.◦ Identify personal issues in athletes game plan to
improve on. Goal Setting
◦ Identify long-term goal.◦ Divide long-term goal in to smaller achievable short-
term goals. Imagery
◦ Use of visualising success in races and faster running velocities.
Psychological Needs
Athlete needs to remain in energy balance. (Energy coupling)
Glycogen stores optimised before training. (upper limit of storage~1050g)
Glycogen stores replenished post training. (Ivy 2001)
Keep hydrated and in fluid balance at all times. Adequate protein & essential fatty acids. To achieve RDA’S of all vitamins, minerals and
trace elements.
Nutritional Needs
Baseline Testing- VO2 max test- Lactate Testing- Food diary- 3 day food and
hydration diary kept- Training diary- Athlete has
kept a detailed training log over the past year

Training intervention
No interval work Rest days-training days not always
consistent ratio Sessions tend to mainly consist of long runs Very little pacing work Some hill work and jogging on uneven
terrains but structure needs to be implemented

Nutritional Recommendations
3 Day Food diary completed for 2 week days and a weekend day. (Yang 2010)
Fluid intake contained mainly energy drinks, fizzy drinks and coffee.
Carbohydrates came from mainly white sources.
Diet includes little protein Fruit and vegetable intake is limited.
Food Diary Findings
Cut energy drinks and fizzy drinks: replace with more water and isotonic sports drinks.
Cut coffee intake: replace with herbal teas
Weight in and out of training sessions to determine fluid loss. Try and replace fluids lost. 1 litre per kg lost
Keep alcohol to a minimum
Fluid and Hydration Advice
Aim for 5 fruit and vegetables a day. Add alternative snacks: nuts, fruits, yoghurt,
vegetable sticks etc. Try replace white carbs with wholemeal ones. and maintain a low GI diet except for post
training High GI foods are best to ensure glycogen replenishement. (Sui & Wong 2004)
Add more protein in the form of lean meats i.e. chicken, turkey or from non meat sources i.e. eggs, pulses.
Food Intake Advice
Has good breakfast timings for replenishing overnight depletion of glycogen stores.
Try to eat as soon as possible after training to replenish stores lost in from exercise. The sooner the better. (Ivy 2001)
Time snacks before training to get maximum energy. (Hawley & Burke 1997)

Butler and Hardy (1992)
Outcome Goals Ultra marathon: 33 miles Then….53 mile race
● Process Goals Focus on improving pacing Overcome nerves
Pre Performance Routine?
Goal Setting
Can be used before and during a race to maintain focus and concentration – help lower pre race nerves?
“I can maintain my pace throughout” “ I will run better than my last race” “I don’t need to overtake to run well”
Mission Statements
Self Talk
Imagery as part of a pre performance routine can help with pacing and nerves
Use imagery to see himself in races not overtaking, but maintaining his pace
Encouraging imaging to be carried out before a race in correct environment/clothing
Making the image feel real
Imagery
Positive self talk Imagery
A pre performance routine will enhance focus and concentration leading up to a race and take mind off any nerves – more likely to perform better
