An Assessment by a Registered Dietitian with experience in Sports Nutrition should include:

Body Composition Assessment

 

Body Composition Assessment for hydration (BIA), muscle mass and fat mass for your sport and position played. A test can show if athletes are anabolic or catabolic. Periodic testing shows if athletes are meeting their goals.

 

Hockey

What position do you play? Did you know that you may have a different body type and muscle mass depending on the position you play and the training you do to be your best in your position. Goalies have a large muscle mass and are more like 'body building gymnasts'. Defensemen or women like to be strong and fast and may carry more body mass than other team members. This is important as defenders. Forwards like to be fast and train to have short bursts or energy in 30 to 40 second intervals. More recently forwards are becoming taller and still very fast.  Nutrition needs are different for these positions.

Hydration is very important in all sports. Do you know how much weight (water) a goalie loses in a game? How much does a defenseman lose? Weigh yourself before and after a game. For every pound of weight (.5 kg) loss athletes need to take in more than 600 ml of water or 2+ cups.

Vitamins and Minerals

Dietary Recommended Intakes (DRI)

Registered Sports Dietitians Assess


•Sport energy expenditure •Current intake with a computerized intake analysis •Body composition needs for sport using a clinical bioimpedance •Estimation of overtraining •Fluid loss in training and replacement •Lab data from your MD (Hgb, ferritin, immune system tests) •Training Plan •Competition Days Plans •Travel needs and food intolerances •Make a meal plan and recommend supplements


Carb Replacement During Training

Athletes Can Begin to Replace Carbs in training after the first half hour (if they are not upside down)This depends on your muscle mass and stage of growth. More muscle mass adds more carbs per half hour

20-30 gms carbs every 30 minutes


Drink (per 100 ml)              Carb gms       Sodium mg             Potassium mg


Orange Juice                    10                       1                            200

* Also contains Ca: 5 mg, Mg: 5 mg, Zn: 1 mg


Recovery After Training

Within 15 minutes and again at 2, 4, 6 hours post exercise 40 to 100 grams of Carb

Examples of 75 grams of Carb

  1. 375 ml (12 ounces) orange juice and 1 bagel with2 slices of meat or cheese
  2. 500 ml (16 ounces) of choc milk and 1 bagel

•Fluids

Losses in Exercise

  • Sweat (super sweater)
  • Respiration
  • Symptoms of Dehydration
  • Fatigue
  • Reduced work capacity
  • Loss of 1% of body weight can reduce muscular work capacity by 5% to 7%
  • Cyclists can work maximally for only 6 minutes
Fluid Needs

Weigh yourself before and after exercise
  • 2+ cups (600 ml) water = one pound
  • losses 2 pounds per hour = 1.2 litres
  • gut absorbs 1 litres per hour
  • take fluids before, during and after activity
  • may choose water or use a drink with glucose (7.5%) & electrolytes
  • don’t wait for thirst, its too late

Rowing

Rowers are unique athletes who train in endurance and power and compete in sprints.   These unique demands have important needs. Athletes will lose muscle mass and drop or slow their progress without good diet and impeccable timing of food intake. Nutrition Assessment specializes in weight class sports and has a proven record with weight loss and top performance in competition with rowers. The Queen’s University light weight womens' program is second to none in Canada. Race days require careful planning for optimal timing of food intake and race times.

Erin Armitage, rower and fellow sports dietitian has written a series of article on Rowing Nutrition.  The below link has the initial article on hydration and to receive the full set of article register and contact us to receive them all.

Football

Football players are unique athletes who train in power and compete in sprints. These unique demands have important needs. The blocker will be a totally different body composition and nutrient needs than a quarterback. Athletes will lose muscle mass and drop or slow their progress without good diet and impeccable timing of food intake. Nutrition Assessment looks at optimal weight for each position. Like no other sport football requires excellent eye-hand coordination which means even blood glucose levels for both training and games right until the end of the last quarter. Nutrition Assessment can provide solutions for these challenges.

Endurance Sports

Sports such as cross country running and skiing, triathlon, cycling, mountain biking, biathlon, distance swimming and sailing require special attention to nutrition for training and competitions. For example endurance athletes who no longer use red meat and or have chosen organic grains and cereals may be at risk of anemia and need their hemoglobin and ferritin checked every 3 months.

Extreme or Ultra Exrtreme Sports

Training for extreme sports requires a healthy intake and sometimes results in unwanted weight gain. A nutrition assessment helps athletes assess effective muscle mass and target ideal weight for training and for the competition. Adequate intake of all nutrients prevents injury with the many hours of periodized training all year round. An example of a an Ultra event would be the training for ultramarathons, the Death Race or the Mantracker TV series. In these events, total nutrition on the go is required. Athletes must learn to eat whole foods in these events and cannot survive on power products alone.

Rugby

Rugby is a sport that attracts athletes of many different body types and thus varied nutrition needs

Volleyball

Basketball

Exercise Record

Weight Class athletes can maintain muscle and reduce body fat to perform at their optimal level. For effective weight loss a dietitian can provide optimal protein recommendation and assure minerals are balance to allow normal levels of body water.

Weight Class Advice

Weight Class athletes can maintain muscle and reduce body fat to perform at their optimal level. For effecive weight loss a dietitian can provide optimal protein recommendation and assure minerals are balance to allow normal levels of body water.

Food Intake Analysis

Food intake Analysis is the best way to determine calorie needs in addition to estimates from computer models for nutrition and activity. To Download a food diary click here.

Weight Management Advice

When reducing body fat for sport most people who only change their diet and not their activity will have a drop in their metabolism of up to 200 kcal/per day.

Lab Reports

Relevant laboratory values related to your sport. Eg hemoglobin and ferritin

Patient Progress Reports

Information on hydration and sweat losses in exercise. After an assessment is completed, a nutrition plan from a registered dietitian should include:

A hydration plan based on needs.

  • A sample meal plan or some basic suggestions depending on your goals, learning style and readiness to make changes
  • An idea of what vitamins and minerals may need replacement in your diet
  • Food replacement for exercise
  • A food intake and exercise diary
  • Some targets related to your nutrition and performance goals
  • A follow-up plan
