4 Nutrition for Performance
Nutrition for XC and Role of Coaches Nutrition for Performance Runners bodies need to continuously be fueled and refueled to sustain energy and support all workouts and races. Proper nutrition is essential for performance, progress and health throughout the season and year round. Supporting healthy habits sets the tone for lifelong success and well being.

5 High School Running Nutrition Goals
Nutrition for XC and Role of Coaches High School Running Nutrition Goals Refuel Rehydrate Recover Ideal day starts off with: Prioritizing sleep Having a balanced breakfast

6 High School Running Culture
Nutrition for XC and Role of Coaches High School Running Culture Performance Perfectionism Pressure Typical day starts off with: Lack of sleep and/or Lack of fuel

7 Influential Factors Affecting Eating
Numbers driven Teammate starts “diet” Initial weight loss with faster time Nutrition for XC and Role of Coaches Body image, leanness Influential Factors Affecting Eating

8 Nutrition for XC and Role of Coaches
In spite of this, I had my best year of track to date, and the best year I may ever have. I was an All-American in the 10k, runner up in the 5k and 10k at the Big 12 Conference meet, and ran USA nationals, ending the season with a personal best. Eating disorder or not, I was fast, and I was not about to change my habits that were working so well. Things hurt, my body couldn’t recover from anything, and the life was being sucked out of me.  My last track seasons were filled with a stress fracture, loads of cross training, and a lot of self-disappointment. 

9 Eating Behaviors What we see in high school running community

10 Nutrition for XC and Role of Coaches
Prevalence Eating disorders in 31% of elite female athletes in “thin build” sports compared to 5.5% of control population Disordered eating behavior as high as 62% Prevalence of secondary amenorrhea as high as 65% in long distance runners 21.8% of female high school athletes met at least one criteria of Female Athlete Triad

11 school year, over 769,000 female athletes in high school interscholastic running sports in US Cumulative seasonal incidence of injury for female runners ranges from 34.0% to 52.0%! 1 in 5 runners will sustain stress fracture each year. Evidence shows the three Triad components may place female runner at greater risk for musculoskeletal injury

12 Interrelationships among - energy availability - menstrual function
Nutrition for XC and Role of Coaches Female Athlete Triad Interrelationships among - energy availability - menstrual function - bone mineral density

13 Relative Energy Deficiency in Sports
Nutrition for XC and Role of Coaches Relative Energy Deficiency in Sports Goal of ACSM is for every girl and woman’s physical condition to be coincident with the green triangle, which represents the healthy athlete who adjusts her dietary energy intake to compensate for exercise energy expenditure Thick arrows indicate that energy availability promotes bone health and development indirectly by preserving eumenorrhea and estrogen production that restrains bone resorption, and directly by stimulating production of hormones that promote bone formation. Red triangle = low energy availability impairs bone health and development by inducing amenorrhea and removing estrogen’s restraint on bone resorption, and directly by suppressing hormones that promote bone formation.

14 Triad Components Energy Availability
Nutrition for XC and Role of Coaches Triad Components Energy Availability dietary energy intake minus exercise energy expenditure normalized to fat-free mass ( )/51 = 27.5 kcal/kg of FFM/day Menstrual Function Eumenorrhea to amenorrhea. Pituitary gland not secreting pulses of LH (within 5 days of low EA) Bone Mineral Density density and internal structure of bone mineral and quality of bone protein measured by Z score

16 Types of Eating Disorders
Nutrition for XC and Role of Coaches Types of Eating Disorders Anorexia consistent restriction of energy intake, distorted perception of body image Bulimia binge eating, loss of control compensating via laxatives, purging, exercise, etc Other specified feeding and eating disorders (OSFED) Psychological and biological based and triggered by emotional and cultural factors

17 Consequences of Negative Energy Balance
Nutrition for XC and Role of Coaches Consequences of Negative Energy Balance Delayed recovery Inability to adapt to training regimen Diminished performance Loss of the cushioning and insulation in the body Decrease in fat and lean tissue used for fuel Compromised immune function, respiratory infections Nutrient deficiency Psychological problems associated with eating disorders Loss of the enjoyment of eating and social dining occasions Overtraining syndrome

18 Negative Energy Balance
Nutrition for XC and Role of Coaches Negative Energy Balance Well fueled athlete will always outperform the under fueled athlete “In athletes, dieting may not lead to clinical eating disorder but rather situation when athlete is told to lose weight and the availability (or lack thereof) weight loss guidance” – ACSM on Female Athletes

19 Consequences of menstrual dysfunction
Nutrition for XC and Role of Coaches Consequences of menstrual dysfunction Hormonal imbalance, endocrine dysfunction Low hormones influences bone formation and remodeling and encourages the withdrawal of calcium from bone Stress fracture 2-4x higher in amenorrhea athletes Infertility Impaired endothelium vasodilation Impaired skeletal muscle metabolism Elevated LDL

20 How to Recognize Behavior Change
For the health and success of your athletes

21 Risk Factors Nutrition for XC and Role of Coaches
At risk for low energy availability: Restrict dietary energy intake Exercise for prolonged periods Vegetarians and vegans Limit types of food intake Low self esteem Family dysfunction Abuse Biological and/or genetic factors Injury Change in “rank” on team

22 Signs and Symptoms Nutrition for XC and Role of Coaches
Anyone is susceptible so be aware of your athletes Preoccupied with food, weight and/or body Dehydration Gastrointestinal problems Intolerance to cold Mood swings Fatigue Weight loss Difficulty concentrating Refuse to eat with teammates Frequent injury

23 Nutrition for XC and Role of Coaches
NCAA – “coaches have considerable influence with their athletes…their motivational climate can influence the risk of disordered eating.” Create community of psychological support and openness Not to criticize (judgement in sport) Provide resources/guidance Encourage optimal fueling for prevention and performance in sport

24 Prevention How to be proactive with your athletes

25 Prevention Education on fueling for performance Open communication
Nutrition for XC and Role of Coaches Prevention Education on fueling for performance May need up to 3,500 calories Open communication Set expectations to train hard and eat healthy Deemphasize weight, focus on other aspects that make up running Pre season physical, biomarkers, growth curves Screening tool (EAT-26) Self report measure of symptoms and concerns characteristic of disordered eating

26 Runner Performance Screen
Nutrition for XC and Role of Coaches Runner Performance Screen Do you currently or have you ever had a stress fracture? Do you ever feel abnormally fatigued during the day or have noticed a decline in your energy at practice? Have you gained or lost 15 pounds or more in the past 3 months? Do you think you need or want to gain or lose weight in the next couple months? Are you experiencing any recurring GI distress, bloating, diarrhea, constipation, etc? Do you exclude any food groups from your diet? Do you skip breakfast or any other meals during the day?

28 Intervention

29 Intervention as Coach When: Nutrition for XC and Role of Coaches
Frequent injuries Stress fractures/low BMD Absent menstrual periods Compromised immune system Inflammation Negative body image/food talk Rapid weight changes Blood work indicative of nutritional deficits (vitamin D, electrolytes – sodium/potassium, ferritin, thyroid, cortisol, insulin, LDL, growth hormones)

30 Intervention as Coach:
Nutrition for XC and Role of Coaches Intervention as Coach: HOW: Meet in private Express concern Respect your athlete Tie to performance (main goals for the season, for race day, recovery) Provide tangible benefits (bone healing, faster recovery from injury, increase in energy levels, concentration)

31 Tips for the season Know the components of the Triad
Nutrition for XC and Role of Coaches Tips for the season Know the components of the Triad Recognize signs and symptoms early on Initiate open communication and positive reinforcement Coaches are the front line for identifying early signs and influencing the athlete!

32 Nutrition Education for your runners
Nutrition for XC and Role of Coaches Nutrition Education for your runners Jenna Stangland (952) option 3 Education session with parents & athletes Nutrient timing, quality of fuel, supplementation, affects of hydration/dehydration, nutrient deficiencies
