Hey guys, I am curious about all you runners/joggers out there. Do you go for a run or jog the night before a big match or your first match in a tournament? I know that many of the days I play that if I've gone for a run (3+ miles) the night before, I truly do feel better while playing the next day. I feel like I've got some extra energy and extra endurance. Whether it is a real physical side effect of the run or something mental, I know that I feel better. I expect better play after a jog. I also know that if I play 5 hours at a time and try to play the next day, I am completely worthless and my level drops a few notches. Sometimes days that I've run before playing tennis, I am also worn out. I tend to play to the point of really wearing myself down and I obviously don't recover from that in one night. I expect a lower level of player if I'm out for the second day in a row. So my question is, what do you guys think about a jog or a run the night before playing an important match? Are there benefits? Is "freshness" more important? What all is at play here? Is it the amount of time spent on the activity? Is it how strenuous the activity is? Am I really gaining a near-instant benefit from a run? Am I insane?
