GO THE DISTANCE WITH THE NSPCC’S MARATHON TEAM


W


e would love it if you could join the NSPCC’s teamGO for the Virgin London Marathon 2011.


We need your spirit, passion and determination to help us raise over £1 million. This money will help our vital ChildLine service. ChildLine is the UK’s free, confidential helpline for children and young people. Trained volunteers are on hand to provide advice and support, by phone and online, 24 hours a day. The Virgin London Marathon is a tough


but incredible challenge. We will support you every step of the way. You will receive dedicated training support from Olympic athlete and Commonwealth Games medal winner, Liz Yelling. You can record every step of your training in your free diary, and teamGO’s training plans will help you get in shape for one of the biggest days of your life. And don’t worry, when that day comes, we’ll be there, cheering our lungs out. Once you reach that finish line the teamGO after race party can offer you some well-deserved refreshments and a great massage. Just what you need after


26.2 miles. Paul Day, one of teamGO’s 600 members, ran the marathon with the team in 2010. He said: “The marathon is one of life’s must do’s. The thought that you are raising money for children that have been abused really drives you forward. And everyone at teamGO was great. The after race party was a lifesaver. I never thought a massage would have felt so good!” So if you have your own place in the


Virgin London Marathon 2011, join the NSPCC’s teamGO today and make a massive difference to the lives of vulnerable children. To register or for more information contact gorunning@nspcc.org. uk or call 020 7825 2621. Registered charity numbers 216401 and SC037717.


THE SCIENCE BEHIND COLOSTRUM E


xercise induced gut disorders are common in runners. Runner’s trots is a popular description, but as well as


diarrhoea, cramps and nausea symptoms this problem can also spoil your performance. Medical researchers at Queen Mary’s Medical School in London and sports scientists at Aberystwyth University have joined forces to investigate the cause and the remedy. A group of 12 athletes were asked to


run for 20 minutes at 80 percent of their aerobic maximum. At the end of their run they drank a solution of complex sugars with molecules normally too large to be digested through a healthy gut wall. To the extent that these do enter the bloodstream they can be collected in urine in the following hours to measure the increase in gut permeability. Each candidate’s core temperature was taken. After 20 minutes their core temperatures rose by two degrees and their gut permeability increased by 250 percent. When the group were given a drink of dairy colostrum for two weeks before the trial their permeability increase was

reduced to just 40 percent despite the same effort and temperature rise. Laboratory studies identified the


changes in gut barrier function. Gut cells were cultured at normal 37 degrees body heat and also at 39 degrees to replicate the temperature after exercise. The death rate of gut cells was much increased at the higher temperature. When colostrum was added to the culture medium this rise in cell death rate was reduced by two thirds. The body’s response to increased permeability is to clear the gut contents to avoid toxins from gut organisms entering the bloodstream as these lead to heat stroke, where our internal organs suffer damage. Last year, Neovite sponsored veteran


runner, world record holder Cecilia Morrison took two European gold medals in Hungary despite 36 degree ambient temperatures and high humidity. Cecilia reports fewer heat stress symptoms since starting colostrum four years ago. For more visit www.neovite.com.
