4 Foods to Eat Before a Run
If you run, you've probably experienced occasional digestive discomfort. At best, this annoying little side effect can limit your performance. At worst, it can become so intolerable that it forces you to abandon your run altogether. In severe cases, it can even present health risks. 'Gastrointestinal problems are common, especially in endurance athletes, and often impair performance or subsequent recovery,' notes an analysis published in Sports Med. 'Generally, studies suggest that 30–50% of athletes experience such complaints.' No fun at all. Luckily, there are certain foods that can help mitigate the effect—and optimize your performance. Read on to find out exactly what you should be eating before you hit the road for max results. Running and digestion Here's what's going on to cause the upset: When the body exerts physical effort, it redirects blood to the muscles in order to supply them with as much oxygen as possible. This redistribution reduces blood flow to the digestive system, disrupting its function. This can happen during any intense physical activity, and is the reason that most of us were told not to swim right after eating as children. But running is also a high-impact sport, which creates a bit of a double whammy—literally. Each step against the ground results in a shockwave of vibrations that travels up the legs to the body's digestive organs, creating discomfort and cramping. The role of diet and timing Nutrition is the cornerstone of fitness—and for runners, timing is everything. To give the body adequate time to digest before a run, here's a good rule of thumb: Wait two to three hours after a meal, and 30-60 minutes after a snack. Avoid foods that are high in fat, protein, and fiber—all of which are extra difficult and time-consuming to digest. Just as some foods can make digestion difficult before a run, other foods can optimize energy and boost performance. A good pre-run meal or snack should include easy-to-digest carbohydrates to support the body and boost performance, as well as protein to help stabilize blood sugar. 'Appropriate nutritional choices can reduce the risk of gastrointestinal discomfort during exercise by ensuring rapid gastric emptying and the absorption of water and nutrients and by maintaining adequate perfusion of the splanchnic vasculature [abdominal nerves],' the aforementioned review notes.

Heart issues among endurance athletes studied by scientists
Older male endurance athletes may be at higher risk of heart scarring and related complications, according to a new study. Sudden cardiac death is a 'leading cause of mortality' in athletes, experts said as they set out to investigate whether endurance athletes had heart scarring and linked heart rhythm problems. Academics studied 106 former competitive cyclists and triathletes who exercise for more than 10 hours a week for at least 15 years. Experts from the University of Leeds scanned their hearts and had an implantable loop recorder fitted to assess their heart rhythms. They found that 50 of the 106 athletes (47%) had scarring on their hearts, particularly in the left ventricle – the main pumping chamber of the heart. This compares to 11% of 27 non endurance athletes studied for comparison. During a two-year follow up period they found that 22% of the athletes had an abnormal heart rhythm, according to the study which was funded by the the British Heart Foundation and published in the journal Circulation: Cardiovascular Imaging. They concluded that the athletes who had heart scarring were over 4.5 times more likely to experience an abnormal heart rhythm episode – which is linked with an increased risk of sudden cardiac arrest – compared to those without scarring. It is thought that among endurance athletes scarring could be caused by levels of exercise when the heart has to work even harder to pump blood. Dr Sonya Babu-Narayan, clinical director at the British Heart Foundation and consultant cardiologist, said: 'There's no doubt that exercise is good for our hearts – it helps to reduce blood pressure and cholesterol, manage our weight, and it boosts our mental health. 'But in some veteran male athletes, this early research suggests that intense exercise over many years may have affected their heart health. 'More research in veteran endurance athletes – both in men and women – will be needed to identify the small number of people who have the kind of heart scarring, together with other risk factors, that mean their life could be saved by having an implantable defibrillator.' One of the athletes who took part in the trial was Brian Cookson, keen cyclist and former president of British Cycling and Union Cycliste Internationale – cycling's world governing body. The 74-year-old grandfather from Whalley, Lancashire, said the trial could have saved his life. While training at the Manchester Velodrome he started feeling unwell and his sports watch recorded his heart rate had reached 238 beats per minute (bpm), and stayed that way for around 15 minutes. 'I was pushing it a little bit on the track, but not absolutely full gas, as we say in cycling,' Mr Cookson said. He contacted the team involved with the study who reviewed data from his implanted device to record his heart rhythm. They were able to see he had suffered an episode of ventricular tachycardia – an abnormally fast heartbeat where the heart's ventricles contract too quickly and do not pump blood around the body effectively. 'The next day, I got a call. They said, 'Stop riding your bike, don't do anything more strenuous than walking until we can get you in here because we think you need an implantable cardioverter defibrillator (ICD)',' he said. He was fitted with one of the devices in August last year which shocks the heart if it goes into an abnormal rhythm. Mr Cookson, who is still cycling, said: 'I keep a closer eye on my heart rate now and if I'm getting to 150bpm I'll start backing off. 'I'm so grateful to have been part of this study. It might well have saved my life. 'Without it, I might have carried on pushing myself until something more serious happened.' Dr Peter Swoboda, associate professor in cardiology and consultant cardiologist at the University of Leeds, who led the study, said: 'In our study, the athletes who experienced dangerous heart rhythms often had symptoms first. 'I'd encourage anyone who experiences blackouts, dizziness, chest pain or breathlessness, whether during sport or at rest, to speak to their doctor and get it checked out. 'These results shouldn't put people off regular exercise. 'Our study focused on a very select group, and not all the athletes involved were found to have scarring in their hearts. We can all benefit from being more active, and this study is an important step towards helping people take part in sport as safely as possible.'
