COACHING NUTRITION cholesterol, and higher intakes of fruits, vegetables, whole grains, nuts, soy products, fibre and phytochemicals. KEY NUTRIENTS NEEDED The key nutrients for vegetarians include protein, omega 3 fatty acids, iron, zinc, iodine, calcium, and vitamins D and B12, as these nutrients are often deficient. These deficiencies are often associated with the avoidance of animal foods and products. Vegetarians that include milk and other dairy products, eggs or fish are less likely to suffer from these nutritional risks than vegans who do not consume any animal products. Vegetarians who consume animal products are still at nutritional risk for these nutrient deficiencies, but through careful dietary planning and the intake of selected nutrients these are easily overcome. The Veggie Runner It’s possible for vegetarian athletes to perform well, to be healthy and to have an injury risk no higher than that of other athletes. All they need to do is follow a planned diet containing the necessary nutrients that the body demands. – BY ESMÉ MARÉ, REGISTERED DIETICIAN A vegetarian diet is one that does not include meat (including poultry) or seafood, or products containing these foods. There are many reasons for adopting this lifestyle: To improve one’s health, to boost performance, adherence to spiritual or cultural guidelines, to protect the environment, or to abide by a love for animals. Vegetarian diets are appropriate for all stages of the lifecycle, including pregnancy, lactation, infancy, childhood and adolescence, and athletes can also embrace the benefits of a meat-free eating plan. In terms of benefits, vegetarianism is associated with lower body mass index and lowers overall cancer rates. Vegetarians also appear to have a low-density lipoprotein cholesterol level, lower blood pressure, and lower rates of hypertension and type 2 diabetes than non-vegetarians. Added to that, the diet is associated with a lower risk of death from heart disease, and vegetarians have a reduced risk for chronic diseases because they have lower intakes of saturated fat and T he treadmill can be a lifesaver when it’s dark outside or the weather is bad, but running on a moving belt – especially if it’s too fast for your fitness level – can affect your stride, or worse, lead to specific injury patterns, notably hip-flexor strains among runners who put a lot of miles on the belt, as well as shin, Achilles or ITB pain from running with an overly narrow stance. So, if a treadmill is an important part of your running, consider these strategies for keeping your body healthy. 1. TRAINING INSIDE, RACING OUTSIDE On race day you could face variables such as hills or headwinds, so it’s better to do your long runs outside, but if it’s a choice between a treadmill long run and no long run at all, because of rain, gale force winds, or ice and snow, then hit the belt... but try to vary your pace and incline as much as possible, to resemble the terrain you’ll encounter. Adding a percentage point or two of incline at times will take care of the hills, and will also contribute to varying your pace. Even if you keep the treadmill on the level, vary your running speed instead of trundling at the same pace the whole way. 2. RUNNING ON AUTOPILOT Doing the same workout over and over, at a comfortable pace and incline, can cause problems down the proverbial road, because the belt’s flat, uniform surface works your muscles and joints in a repetitive way. Normally, out on the roads or trails, you would encounter hills, turns, pavements, rocks and more that force your However, consuming the nutrients and the energy you need to participate in endurance events becomes more difficult as you eliminate food groups. Creatine is found to be lower in vegetarian than in non-vegetarian athletes, as its synthesis is not sufficient with low meat intakes. This poses some performance-based concerns. The vegan diet is also associated with the risk for dysmenorrhea, anaemia, vitamin D deficiency and impaired calcium and zinc status. Furthermore, in vegetarianism, the total energy intake is often inadequate and protein gets broken down to satisfy the body’s energy requirement before other anabolic muscle-building or muscle recovery processes can occur. PLANNING MEALS Meat, fish and poultry contain all nine of the essential amino acids, which makes them complete proteins, whereas veggies, beans, lentils, plant proteins and grains are incomplete proteins. Therefore, athletes consuming vegetarian meals should plan their meals in ways that optimise essential amino acid availability. Combining legumes and cereals (samp and beans or rice and lentils), legumes with seeds and nuts (hummus), grain and dairy products or nuts and seeds and dairy products (macaroni and cheese, or muesli and yoghurt) at the same meal ensures for a good distribution of all essential amino acids. With the availability of new products including fortified foods such as soymilks, meat equivalents, juices and breakfast cereals, and dietary supplements, it is possible for vegetarian athletes to meet their key nutrient requirements.

So, if you’re running regularly on a treadmill, try using various preset programmes, doing hill work some days and changing up the pace. The slower uphill workouts build strength and power, while faster flat workouts build stamina, endurance and foot speed. 3. TOO MUCH SPEEDWORK You might enjoy cranking the treadmill up to max speed and then sticking it out for as long as possible, or your time on the treadmill runs out, but because the treadmill keeps moving even as you tire, you may end up over-striding and landing with your foot too far ahead of your body. That can lead to knee, hip and hamstring pain, so try to match your treadmill stride rate to your road stride rate – if your treadmill rate is lower by 10% or more, chances are you’re struggling on the belt and over-striding, thus putting a new stress on your body. Sprinting flat-out on the treadmill may be fun, but is not particularly good for you. 4. PREPARE FOR HARDER SURFACES The treadmill belt offers a relatively soft landing, so prepare your body for racing on harder surfaces: • Strength-train twice a week (lunges, squats, hip extensions, planks, push- ups). • Run outdoors at least once each week during the last four weeks of training. 69
