A man's sprint time in the 100 meters is more relevant to tennis than the ability to run a 5K at good time. Tennis points, even at the professional level, are more like jumping rope a little and then shuttle sprinting back and forth. Distance running isn't very relevant to tennis except to the extent that it develops cardio endurance.
yes but a good Aerobic base is required to reach high Levels of anaerobic endurance. you can reach solid Levels with just shuttle drills and other anaerobic drills but to reach a really high Level you Need a good Aerobic base. you don't Need to be a specialist but I'm sure todays pros have a very good Aerobic endurance.
