That finding refers to endurance athletes who were continuously bicycling for an hour. It is unclear that it would apply to recreational tennis which is more anaerobic, where the heart rate has a chance to rest every ten minutes or so, and where the large uppper leg muscles are much less stressed. In most tennis matches players aren't huffing and puffing like they would in bicycling or endurance running. In other words there is more opportunity for blood flow to reach the intestines when playing tennis than when performing pure endurance exercise, so intestinal leakage might be minimal. I doubt that recreational doubles players would experience it at all. It would be useful to test tennis players to see.
