Sprints / Hurdles / Jumps / Throws NUTRITION FOR SPEED ATHLETES These notes accompany the presentation given by Glenn Kearney on ‘Nutrition for Power Speed Athletes’ held in Loughborough on Saturday 21 May 2011. BASIC NUTRITION PRINCIPLES
1. Eat frequent, small to medium sized meals Eating in excess at one single meal combined with infrequent meals throughout the day can lead to poor training gains and poor recovery. This feeding pattern can lead to loss of lean body mass and an increase in fat mass.
Eating frequently and choosing healthy food choices such as high quality low fat protein, complex fibre-‐rich carbohydrates, and good fats are essential for all athletes who are training to gain lean body mass and maximal strength.
A small meal consisting of a complex carbohydrate, protein and good fats should be eaten 5-‐6 times per day. This usually translates into a small meal every 2-‐3 hours throughout the day. This type of feeding pattern will help to keep your energy levels high and to give you the proper nutrients for recovery between hard workouts.
2. Eat protein with all meals Protein is a very important nutrient, especially for athletes who are trying to increase maximal strength and lean body mass. There is strong evidence pointing to the importance of having a little bit of protein with each meal to assist with increasing lean body mass along with .
It is critical that you choose good sources of protein. Some good examples are; milk protein blends are yogurt, low fat cottage cheese, whey protein, and casein protein. Other good sources of protein are: chicken, low fat beef, canned (or fresh) tuna/salmon, prawns turkey, egg whites, all fish, lean pork cuts, and finally nuts and seeds.
Remember all your meals should contain some protein. Most experts recommend approximately1.5 grams of protein per kilogram of body mass for healthy adults who are engaging in daily rigorous physical activity. There is evidence that high performance athletes can achieve even better results with 2.0 to 2.5 grams of protein per kilogram of body mass. To determine the appropriate protein intake multiply your body weight (in kg’s) by 2.0. For example, an athlete weighing 80 kg would need:
80 kg x 2.0 grams = 160 grams of protein/day
It is critical to mention that you do not need to eat excessive amounts of protein to gain muscle. Having small frequent meals throughout the day, and a good hourly energy balance is far more critical for gaining muscle.

3. Eat more food after training During exercise your body’s protein structures are broken down and carbohydrate stores are depleted. Following exercise your body is “hungry” to replace these nutrients. It is critical that out of your six meals in the day that the biggest meals are eaten following your workout.
Once again, choose healthy carbohydrates, fats and proteins.
4. Zero tolerance for sweets and fatty carbohydrates Your body is a temple. Eating sweets and fatty carbohydrates such as potato chips, high sugar juices, fizzy drinks, chocolate bars, ice cream, chicken wings, and most pizza’s should be avoided by athletes.
Eating sweets and fatty carbohydrates will result in increased fat mass, big blood sugar fluctuations, and poor recovery. If you are serious about your training, you will have the self-‐discipline to completely avoid these items.
5. Drink plenty of water Throughout the day you lose body water in sweat, breath, tears and other fluids. For athletes this is a huge concern because even a small change in hydration levels can cause decreases in performance.
Proper hydration is crucial for all athletes. You are advised to carry a water bottle with you throughout the day. Sip the water at frequent intervals to maintain hydration. As an alternative to coffee, drink green tea.
PRE- AND POST-WORKOUT NUTRITION
Rationale • Evidence strongly suggests that the acquisition of muscle protein is a result of the
workout stimulus PLUS the proper nutrition during the workout and more importantly during the 24 hours immediately after the workout.
• As a result of this evidence, it is critical that you begin to either: improve, refine or continue the use of proper nutritional recovery strategies.
General Recommendations • Mix 0.8 g/kg body mass of carbohydrates with 0.4 g/kg body mass of protein in 1 L of
water pre-workout. Drink this throughout your workout. For example Sports drink and whey protein.
• Mix 0.8 g/kg body mass of carbohydrates with 0.4 g/kg body mass of protein in 1 L of water post-workout. Drink this after your workout. A good mix is Gatorade and whey protein.
• Have 2-3 tbsp of flax oil or a high quality fish oil throughout the day. Essential fatty acids are very important for your health and recovery.
MAKE ABSOLUTELY SURE that you eat plenty of high quality, nutrient rich food in the 24 hours post-‐workout-‐ if you miss one meal you are IMPEDING your recovery. Every workout contributes to an accumulation of proteins-‐ if you eat poorly for 30% of your meals you will be missing 30% of your results!

• Pivotal
• Major player in behaviour modification & feedback/feedforward with nutritionist – if you have access to one. Aim for the “1 - 2” combination.
• Often intimate knowledge of family life, therefore food environment…
• “Tell me what you know about this individual...? How do you push their buttons?”

Physiological and Metabolic Changes During Intense Exercise
Description Change Description Change
ATP levels Depleted Muscle damage Increased
Muscle glycogen
Partially depleted
Immune system Suppressed
Cortisol levels Increased Inflammation Increased
Protein degradation
Increased Fluid loss Increased
Cell membranes - the local control centre
• DNA is merely the hard disk - the nucleus is merely the ‘gonad’
• Real “brain” of the cell is the membrane - the interface between the exterior and interior
• Nutrients, hormones, neurotransmitters
5/23/11

Nutrient Timing • Why it’s important...
• Each day…eat every 2 to 3 hours… consider Raph’s adapation
• Bfast - King, Lunch - prince,…..
• Within a week?
• In your seasonal phases?
Testosterone (T) • T will enhance strength, increase muscle protein synthesis
• Causes additional GH release
• IGF release
• Contributes to neural improvements seen from strength training Cell Mol Neurobiol 16: 357–382, 1996
• Increasing T naturally pre & post training/competition offers a competitive advantage to the athlete
• Ways to prevent levels dropping below normal during periods of over-reaching will also be of benefit
• Excess stress (physical, mental/life) lowers T/C ratio
5/23/11
5
INCREASE; zinc rich foods (essential for T metabolism)
• Grass Fed Beef ! pumpkin seeds, Oysters, ginger root, lamb chops, split peas, brazil nuts, soy lecithin, black pepper, paprika, mustard, chilli powder, thyme, cinnamon, sardines, almonds, walnuts, rye, oats, tuna, anchovies, and haddock
• B complex foods and supplements – support gene transcription and protein synthesis - Methylation
• Good fats – some cholesterol necessary – EGGS !!
Naturally boosting Testosterone
• Anti-Oxidants – protect lipids in membranes and lipoproteins
• Curcumin (turmeric) and other spices
• Vitamin C foods and supplements
• Mixed Vit. E rich foods; increase organic raw nuts and seeds, one handful of nuts per day suggested
Optimising free testo uptake
5/23/11
6
• Optimise receptors… increase clearance of T… signals lowering T to the brain… increases endogenous T production ….
• Carnitine-L-Tartrate (1.5 g) – very promising different in structure & function to L-carnitine Kraemer, et al. 2003; Kraemer, et al. 2006; Volek, et al. 2002)
Receptors – “Docking sites”
• Cortisol is released in response to stress. Increases the “running rate” of the body to cope with stress (also low blood glucose.
• Illustrates importance of stable blood glucose – low GI meals
• A two edged sword. In small to moderate bursts for a short time period it gives a strong competitive edge.
• If too much is released, performance declines, chronic elevation will cause catabolism. Fat & protein catabolism and gluconeogenesis
Cortisol
5/23/11
7
• Glutamine: Lowers cortisol levels (Antonio, 2002)
• Phosphatidlyserine: 600mg shown to reduce cortisol levels when taken after exercise (Starks et al., 2008)
• Vitamin C: 1-1.5g shown to reduce cortisol levels when taken after endurance exercise (Bryer at al., 2006).
• Antioxidants: various antioxidants such as quercetin and polyphenols can help lower cortisol – a tenuous link. However does reduce the levels of free radicals and prevent the cell/tissue damage caused by physical stress.
• Adaptogens (e.g. Rhodiola Rosea): Helps the body to reach a homeostasis thereby reducing stress and fatigue (Olsson et al., 2008).
• L-Lysine and L-Arginine: There are several studies which support the use of these amino acids for normalizing the cortisol stress response in those with high trait anxiety (Smriga et al., 2007).
Possible nutrient cortisol modulators
Enzyme Rich/Anti-inflammatory foods
Anti-inflammatory Compounds:
• Garlic
• Ginger and Thai ginger • Lemon grass • Coriander • Chilli's
• Berries • Tea; green, black, red etc • Grapes/wine
• Olive oil • Chocolate/cocoa, coffee, walnuts,
peanuts, pomegranates, yerba mate, and other fruits and vegetables.
Proteolytic rich foods
5/23/11

Foods that moderate the inflammatory
cascade
• Ginger, Rosemary, Turmeric, Boswellia, Oily Fish, Chili, Carotenoids, Vitamin D, Salicylates
• Some combined commercially eg “Kaprex” by Metagenics
Enzymes - Proteases
Proteases (325 mg pancreatic enzymes, 75 mg trypsin, 50 mg papain, 50 mg bromelain, 10 mg amylase, 10 mg lipase, 10 mg lysozyme, 2 mg chymotrypisn)…. Downhill running…. Placebo controlled…. demonstrated superior recovery of contractile function and diminished effects of delayed-onset muscle soreness after downhill running when compared with the placebo group

NSAIDS and Gut Health Down regulate protein synthesis
Kill GUT FLORA (Fujimori, S., K. Gudis, et al., 2010).
...which produce vitamin K essential for bone repair
Side Effects:
Diarrhoea, Protein loss, Ileal dysfunction
Upper GI
Ulceration, perforation, Bleeding
Blood loss, Malabsorption
“Traditional anti-inflammatory drugs...should, however, be evaluated carefully with regards to gastrointestinal events and their still poorly defined effect on tissue healing.”

Super Sardines
Packed with Omega 3 – as much as Salmon
One can = 30% Daily Calcium, 150 % B12, 65 % Selenium
5/23/11
10
Glutamine
• Potential as cortisol suppressant (Hickson, R., et al 1995)
• Potential as immune supportive agent (Nue, J., & Li, N 2002)
• Cell volumising effect in cells (Candow, D., et al 2001)
• Assists in gut integrity (Lacey, J & Wilmore 1990)
Tyrosine – chicken, turkey, fish, avo’s, almonds, cottage cheese…
• Substrate for catecholamines
• Boosts brain noradrenaline levels (Gelenberg AJ, et al.,1982)
• Useful therapeutically to combat stress & overtraining (Banderet LE, 1989)
• May improve contractile strength of muscle - more likely the perception of fatigue
5/23/11
11
Vitamin C – 500 mg – 1500 mg
• Key component of the immune system and aids the body’s own antioxidant defences
• Mops up free radicals and reduces DNA damage in cells.
• Last 3 years has seen conflicting evidence emerge on the influence to adaptative responses…
• Down-regulates the production of pro-inflammatory cytokines and participates in recycling vitamin E
• A cofactor in collagen synthesis – essential for regenerating tissues. Poses a issue
Supplement essentials • Safe & effective…
• The better the diet gets the more supplements you can throw away
• Adherence… Habitual vs booster days… clean days
• ZMA (caution: Copper & Selenium), Omega source, Multi Vit/mineral (Methylation), bone support, powder protein, Green fuel
• Vit C & Proteases variable
• Check Vit D

Common athlete mistakes
• Inadequate & poor quality breakfast... • Large gaps between meals - greater than 3 hrs,
perception this helps control body composition • Too many processed carbs & inadequate protein -
change the athlete concept of protein • Starchy carb’s in wrong part of day - focus on
training ‘window’ • Low vege & fruit intake - educate on super foods,
use smoothies, salads, greens drinks • Fear of fats - re-educate on benefits, cell
membrane function, hormonal drivers, • Thinking of supplements as first line of action
Super breakfasts • Porridge, flaxseeds, coconut, yoghurt, nuts,
berries
• 2-4 Eggs, Poached, fried in coconut oil, scrambled – adjust number of yolks, combine with B beans for more balanced low GI meal
• Salmon, spinach, tomato scrambled – see next slide
• Sardines on toast, tomato puree, avocado, OJ
• Note. Can start with greens and nuts

Meal examples
Burgers – home made Choose grass fed beef, and combine with good salad this can really work for a power athlete – 1 x week, or make into meatballs with a tom sauce.
Protein Salads Just one example below. Huge amount of variations and you do need a large serving. Maximise greens, top with several protein sources eg cajun chicken, tuna, egg’s, beef strips. Ideal for dinner
Some simple food solutions
Egg, salmon, spinach, tom and parsley scramble This could be a breakfast lunch or dinner option, can add carb’s by eating with brown rice, add extra spinach…put it in a wrap. Versitile & quick
PIZZA – Texas thin crust The thin crust and minimal cheese make this a meal of ideal macronutrient proportions – MUST be topped with a salad – eg rocket, avocado, sundried tom.. Feta etc

In a large bowl mix the following
1 -1.5 kg rolled oats1/2 Cup of coconut - either small bits or larger or a mixture1 Cup of Mixed nuts, I use flaked almonds but you could rough chop whole ones, just use raw, I also added in Cashews sometimes and some peanuts, brazil nuts.1 Cup of seeds, use mixture of pumpkin and sunflower (now optional here to give them a little bit of a dry fry, to do this put in a fry pan with no Oil and on a light heat gently warm them, doesn't take long and just move them around the pan... be real careful but this adds an amazing flavour to them -careful not to burn them.1/3 Cup Seaseme seeds, do the same as above but be REAL careful they cook quick, again flavour is AMAZING1 Cup of dried fruit - again I mixed this up, some raisins, sometimes I chopped up apricots, sometime I used dates - experiment1 heaped dessert spoon of Cinnamon - secret ingredient I reckon !!!!
When you start feeling confident with this you can add some other grains (buckwheat etc). Just make a good simple batch to start with then experiment later on.
Transfer to a plastic container for storage.
Preparation the night before (this only takes 2 mins), - In you cereal bowl add enough for Bfast the following morning, cover with water (optional to add some Apple Juice even 100 mls)- ½ grated apple - also optional
Birchers Muesli
Essentially this is a Oat based Muesli with nut’s and dried fruit added to it (Swiss German in origin). It is superb in summer or winter and is best soaked overnight to increase the moisture content of the meal and predigest some of the grains.
Therefore make a big batch and soak enough for yourself overnight or alternatively pour hot water over the individual serves in the morning, cover with a plate for 5 - 10 mins (i.e. while you are in the shower, then stir thru Yoghurt, fruit etc).
Ingredients i.e. you can either extend a commercially pre-packaged Birchers, or make it from scratch, a good way to save money and eat he perfect breakfast cereal.
Quinoa stir-fry with kale, chili and nuts
This makes a tasty, quick meal when hot, but it’s also good packed into a container and eaten cold at lunchtime. Serves two. - Despite Quinoa being the perfect protein carb combo, this meal could do with more protein added, eg chicken, mackeral.
Serves 4-6 people as a side dish
100g almonds or cashews200g quinoa 5 tbsp olive oil 2 onions, peeled, halved and finely sliced 3 garlic cloves, peeled, halved and finely sliced 1 small red chilli, seeds and membrane removed, finely sliced 2.5cm piece fresh ginger, peeled and finely sliced 140g kale (or chard), shredded 150ml vegetable stock Juice and zest of 1 lemon Salt and freshly ground black pepper Soy sauce, optional
Heat the oven to 180C/350F/gas mark 4. Place the almonds or cashews on a baking sheet and bake until slightly golden and fragrant, stirring once, about six to eight minutes. Leave to cool and chop very roughly.
Cook the quinoa according to the instructions on the packet. While it’s cooking, warm three tablespoons of the oil in a large frying pan over a medium heat, then add the onions and fry until softened and beginning to turn golden. Add the garlic, chilli and ginger, and sauté for a couple of minutes. Throw in the kale and stir-fry for a couple of minutes. Add the stock and simmer until the kale is tender and most of the liquid has evaporated. Add the quinoa, remaining oil, lemon zest and juice, and stir to combine. Finally add the nuts, season to taste and serve hot or cold, with a splash of soy sauce, if you like.
Ideal lunch - excellent Protein & low GI carbs takes 5-10 mins.
Serves 1 - 2 people
Ingredients185 gm drained Tin of salmon or tuna in water (optional to use Sweet Thai chili tuna)1 can Chick peas (rinsed & drained) – Low GI Carbs with good proteinHandful Greens – eg, rocket, spinach and/or any other greens, add as much as you want1 Red onion - raw, finely sliced1/2 Avocado - slice and drizzle with lemon juice1 soft boil egg (4 mins in boiling water, give the rounded end a prick with a knife)1-2 Carrots (finely chopped)2 Tbsp Sweet Thai Chilli sauce - I also use a creole sauce sometimes2 Tbsp lemon juice (juice of one lemon)2 – 3 Pinch of salt & pepper
Simply combine all ingredients together,, ensure to drizzle the lemon juice, & sweet chilli sauce then season with salt and pepper to your taste.
Many variations possible. Just think about different protein sources eg. could use boiled eggs, grilled chicken, tuna, turkey etc. I do a similar meal often for my lunch here at Lee Valley, add some more flavor by lightly frying (in minimal oil) a red onion with a finely chopped Chorizo sausage
Flaked Chili Salmon & Chickpea SALAD
This recipe and itʼs many variations are amongst the best solutions to lunch (or a light dinner) I have come across. It provides low GI carbʼs, very good levels of protein, is high in essential fatty acids (via the fish). This recipe came from a book call “mind, mood foods”, the combination of nutrients leaves you feeling more alert than a lunch based around bread, also with a ʻlighterʼ feeling in the stomach also.

Salmon & Spinach FrittataServes 2 to 4, prep time 15 mins, cooking time 15-20 mins
Requires a good skillet (non-stick works best) with metal handle so it can go in the oven.
Ingredients & Method
500 g Potatoes (2 big handfuls)6 eggs (can use just 3 yolks to cut fat down if necessary)150 g Spinach (two handfuls washed)1 red Onion6-8 baby tomatoes100 mls Milk1 tin of Salmon (drained)Lemon Juice (half a lemon should be plenty)2 dessert spoons of Capers - not essential but adds fantastic flavourSmall amount of grated cheese – variety of cheeses Salt & Pepper to taste, pesto also an option
• Clean potatoes, cover with water, add salt and boil until almost tender, drain and allow too cool slightly.
• While the potatoes are boiling drain your tin of salmon, add lemon juice and capers and stir through.• Also chop red onion and sauté on low heat in a dash of oil, can also add tomatoes (whole) to pan.
Remove from pan and set aside• Slice semi-cooked potatoes and lightly brown them in a small amount of oil or existing oil in the
pan.• Add, spinach, onions, tomatoes, salmon & caper mix to the pan and reduce heat to low.• Add your 6 beaten eggs (with a dash of milk) to the pan and give the pan a jiggle so the egg mixture
is evenly distributed. Finally grate a small amount of cheese on top• Leave on heat for a couple of minutes then place in an oven set on 180 degrees for approximately 15
minutes. Remove from oven and let stand for 5 mins. You can also cover with a clean tea towel to retain moisture.
• Serve with a fresh green salad, can drizzle some pesto on top and if you love Tomato sauce then indulge perfect eaten cold the next day also
Variations: Use finely sliced Chorizo sausage instead of Salmon, exchange Asparagus or (fresh or canned) for Spinach. Zucchini is another good vege option. Use Tuna or chicken/turkey as the meat option, add olives etc etc
Step by step it should look like this…
Sausage & White Bean StewServes 2 to 4 ~ prep time 5 mins ~ cooking time 15-20 mins
Ideal quick winter dinner ~ Good low GI carbs ~ Perfect for reheating for lunch ~ Serve on Rice
Ingredients & Method
6 quality Sausages - very important to choose high quality sausages, see insert below.1 red or white Onion2-3 clove of Garlic1 can of white beans - cannellini beans work well1 can of tomatoesSalt & Pepper to taste, can also flavour with a spring of Rosemary, for those that like it HOT, add in some finely chopped chilli at the same time as the onion & garlic.
• Brown sausages on a medium heat in a non stick pan, you may be able to get away with adding no oil as some should leak from the Sausages.
• As the sausages begin to brown move them to the side of the pan and gently fry your chopped onion & garlic in the other part of the pan.
• Once the sausages are browned drain and rinse your beans, add them to the pan (or large pot), and add the canned tomatoes also at this stage. Season to taste with salt and cracked pepper.
• Simmer for 15 to 20 mins on a low heat - you could transfer to the oven at this stage (180 degrees).• While the stew is working its magic cook enough rice for dinner and enough to reheat tomorrow.
These types of meals always taste better the next day !
Variations/additions: You can add some more winter vegetables to this meal to make it go further eg chopped carrots, corn kernels etc.
Sausages - quality is key !
An example from M&S, and not a bad price (2 of these packs for £4.50). If you have introduced yourself to your local butcher then you want to ask for a high meat content sausage, and limited processing of that meat. Then combined with the recipe above it works out to be a well balanced meal.
The sausages to the left are 85 % pork that has been free range farmed. Some sausages can be as low as 60 % meat content and even then is is either processed heavily &/or has been intensively farmed. Avoid these.
