COACHING BODY SCIENCE Custom built & Tailor made In an age where runners are spoilt for choice with regards to running shoes, with manufacturers offering dozens of variations, what may define the end of this decade is customisation and individualisation of running shoes. – BY ERNEST HOBBES I n many ways this revolution is already underway, with the fashion-conscious being able to design their own sneakers by way of colours and materials with the click of a mouse. Some running shoe manufacturers even allow you to select a stack height and heel-to-toe drop of your choosing. Although this is predominantly aesthetic, with limited contributions to performance and injury-prevention, cost has hampered the advancement of fully tailoring running shoes to individual needs somewhat, since much work may still be required to be done by hand. However, automation and 3D printing technology has shattered the ceiling of what was previously felt to be unfeasible. Although all fruits are healthy, there are particular fruits which may provide exceptional benefits to athletes: 1 Bananas: A great source of carbohydrates, which makes them a powerhouse of fuel for your body and muscles. Choose ripe bananas, which naturally have a higher sugar content. Bananas are also great sources of potassium and manganese, which help to replenish electrolytes lost during physical exertion, help to prevent muscle cramps, increase bone strength and endurance, and may help to maintain a healthy blood pressure by maintaining the water balance in your body. Bananas are also an excellent source of vitamin B6, which provides anti- inflammatory benefits. 2 Cherries: One of the most antioxidant-rich fruits and provides athletes with One of the key sectors to customising a running shoe lies in the design of the midsole, especially since this is where most manufacturers boast about the technology and materials used, and the properties they possess. In the near future, not only will runners be able to have their midsoles customised with regards to length and width, but these midsoles will also be designed to provide increased support where needed, based on force profiles for each runner. Currently the research and design departments of some manufacturers are able to scan an athlete’s foot shape and size, record force profiles, analyse running technique, and in a matter of hours printed a midsole designed to optimally suit the runner’s needs. In research settings, the athlete would then run through a battery of tests to determine if or where more improvements in the midsole can be made, and the process is repeated. Although to some extent fully customised running shoes may currently only be available to the very few in the ultra-elite class of runners, it may be of interest to study the effect these personalised running shoes may have on actual running performance. Nike’s Breaking 2 project towards the middle of 2017 probably gave us the best opportunity to determine the effectiveness in controlled “real world” conditions. Although the event was highly controlled with regards to terrain, elevation, and course profile, this was not a laboratory test. So what were the estimated effects on performance of the custom Nike Vaporfly Elite 4%? Considering the shoes were proposed to improve performance by up to 4%, and the best performing runners averaged an improvement of 2.5% (most of which would likely be due to drafting), there may be a droplet of merit to the claim. Additionally it should be noted that those who are at the absolute pinnacle of performance are less likely to see significant improvements, while sub-elite and competitive recreational runners may find greater improvement in performance. Whether custom-designed running shoes have any bearing on performance and injury-prevention is difficult to predict, but the future is exciting with possibility. Only time will tell whether this is just another novelty temporarily capturing our attention, or if this is the opening salvo of a new revolution.

Also high in vitamin E, reducing free- radicals, and may improve stamina during exercise. 5 Citrus: Great sources of fibre, calcium, potassium, folate and vitamin B, oranges also contain a big, healthy dose of vitamin C, which helps to keep the body’s immune system functioning by supporting white blood cell production. Oranges also contain hesperidin, a phytochemical that may lower triglyceride and blood cholesterol levels. Fruity Tips • plenty of health, performance and recovery benefits.
