Body Science Road to Recovery There are several remedies you can try to quicken your recovery after a long run or race, so that you can focus on your next goal sooner – especially if you’re not used to high-impact mileage. We look at some tried-and-tested tips, and debunk some others. – BY SSISA’S ANDREW BOSCH & LAUREN VAN DER VYVER 1 STRETCHING There is little evidence that stretching helps speed up recovery. Stretching before an event can actually reduce muscle power, and long-term stretching reduces running economy, as the muscle-tendon loses springiness. A low running economy, in turn, means that more oxygen is needed to run at a given speed. Nevertheless, there is a point when a runner becomes so inflexible that some stretching is needed. 2 MASSAGE Many runners use it because there is a perception of reduced soreness, but this does not translate to improved strength, power or endurance. Light massage will loosen the muscles, but don’t book that deep tissue massage just yet! 3 COMPRESSION There have been many studies on whether compression garments aid performance and reduce delayed onset muscle soreness, but there’s little effect. However, there is some improvement on enhancing lactate removal (reducing stiffness) and reducing muscle oscillation (the slight vibration you feel in your legs after high-impact running). 4 HOT AND COLD Research focuses on water temperature, length of immersion, depth of immersion, etc. While it may have some benefit in contact sports, evidence of a positive effect in running is minimal. The theory behind the ‘hot/cold’ baths for recovery is that warm water causes vasodilation (the widening of blood vessels), which lowers blood pressure, while the cold causes vasoconstriction, which is the narrowing of blood vessels, increasing local blood flow. The contraction and relaxation of the lymph vessels improves inflammation, too. 5 EATING RIGHT One’s glycogen stores are depleted after a long run and should be restored quickly. There is potential improvement when athletes use whey protein or protein hydrolysate ingested together with carbohydrate post-training, and the amount of protein ingested should be around 20g. 6 RUNNING AGAIN The stiffness felt after a long race is due to muscle damage, and it is best to wait until post-race stiffness has disappeared before training again. The first run should be an easy 20 to 30-minute run, gradually rebuilding to normal training. Don’t go in too quickly! If you’ve been building up mileage for a while, three to four rest days are important. Nutrition The 4 R’s for Recovery After your Two Oceans run, it’s important to eat and drink properly to replenish glycogen stores and to rehydrate. These guidelines will help you to recover quicker, so you can get started on chasing down your next running goal. – BY CHRISTINE PETERS, REGISTERED DIETICIAN REHYDRATE Consuming 20 to 25g of protein soon after exercise enhances repair of damaged muscle and stimulates muscle protein synthesis. Whey protein contains the key ‘trigger’ amino acid leucine, which promotes muscle growth. Dairy also contains whey, so milk and yoghurt have become an inexpensive solution for repair. Replacement of 120 to 150% of fluid losses incurred during exercise is recommended (1.2 to 1.5L for every 1kg lost during the run) within the first one to three hours after your finish. Rehydration solutions and salty foods in meals and snacks help fluid and electrolyte replacement. REFUEL Images: Istock REPAIR REVITALISE Total carb requirement post-exercise is determined by the intensity and the duration of your session. Athletes should have 1g of carb per kilogram of body weight after exercise, at regular intervals (i.e. each hour for the first four hours) and then resume normal eating patterns. It must be stressed that this is for runners who intend training within the next eight to 24 hours. There’s less stress on ultra-runners who intend to take it easy after their long run. Athletes should incorporate a range of vitamins and minerals during
