Discussion Topic … What are some ways to organize your group to optimize training? Keep individualization in mind … athletes will do better with attention to their individual needs

Activity #1: Designing a Set • Break in to 5 groups – coaches with similar athlete age and competitive level. • Each group will focus on 1 energy system • Each group create sample set for their 1 energy system. • Each group presents their set to class for discussion and feedback.
Activity #2: Designing a Practice • Remain in same 5 groups. • Each group creates a 2 hour practice that supports the set they created in the previous activity. • e.g. the group who designed a set to train VO2 Max will design a practice based on a VO2 Max main set. • Each group presents their practice to class for discussion and feedback.

Influence of dietary CHO and training on Glycogen stores Wilmore and Costill, 1994
Functions of Carbohydrate Major energy source , particularly in high - intensity activity Its presence regulates fat and protein metabolism The nervous system relies exclusively on CHO for energy Muscle and liver glycogen are synthesized from CHO
Glycogen • Limited storage in muscle • Anaerobic Training improves glycogen storage • Replacement takes 12 hours to 3 days depending on type of muscle fiber and rate of depletion (intensity and duration of exercise) • Inadequate replacement will compromise subsequent sessions • Consume CHO rich snack immediately after training (0.8 - 1.2g/kg) SNC 301 Module 15
Glycogen Replacement SNC 301 Module 15
Activity #3: Planning a Week • Remain in groups from previous activities. • Each group creates a weekly plan, for a T2C swimmer, based on the average number of practices the coaches in the group have (max 8). • Plan must show order in which energy system was focused on each practice. (top two) • Each group presents their weekly plan to class for discussion and feedback. SNC 301 Module 15
Recovery nutrition Goals: Refuel Repair Re-hydrate Aggressive recovery needed if training more than once per day or training volumes increase SNC 301 Module 15
Recovery nutrition A.S.A.P. Insulin independent glycogen synthesis (30-60 mins post Ex.) Pre-plan and have a portable nutrition source close at hand Fluids: 150% of lost weight or pale urine. 0.8 - 1.2g carb/kg (45+grams) in the first hour and then follow training diet. First snack high on Glycemic Index (GI) then lower GI for later foods. Protein: 10 - 20g every 2 hrs. SNC 301 Module 16
Glycemic Index of Some Common Foods High G.I. (>85) Glucose Sucrose Maple syrup Honey Bagel Candy Corn flakes Carrots Crackers Molasses Potatoes Raisins Bread Soda Med. G.I. (60-85) All-bran cereal Grapes Oatmeal Orange juice Pasta Rice Yams Corn Whole-grain rye bread Baked beans Potato chips • Low G.I. (<60) • Fructose • Apple • Applesauce • Cherries • Kidney beans • Chick peas • Lentils • Dates • Figs • Peaches • Plums • Ice cream • Milk • Yogurt • Tomato soup SNC 301 Module 16
Amount of CHO Highest synthesis occurs with large amounts of CHO 1.0 to 1.2 grams / kg / hour 15 to 60 min intervals for up to 5 hours post exercise Jentjens and Jeukendrup Sports Med 33 (2): 117-144, 2006 SNC 301 Module 16
Practical Tips When appetite is depressed immediately post exercise, there is a preference for drinking fluids rather than solid foods CHO beverages are recommended in the first few hours post exercise Jentjens and Jeukendrup Sports Med 33 (2): 117-144, 2006 SNC 301 Module 16
Dietary Protein Is used for growth, repair and maintenance of body tissues Hemoglobin , enzymes and many hormones are produced from protein RDA for general population - 0.8 g / kg RDA for athletes in heavy training should be approx 2.0 g / kg . This applies to both strength and endurance training

Cue: “How did that feel?” RPE is a measure of how hard the athlete thinks they are working. That is, the total amount of exertion and physical fatigue, combining all sensations and feelings of physical stress and effort.Cue: “How hard did you work?”
