I can see why someone water jogging or doing water aerobics would not want to be splashed. I do water aerobics and I wear glasses while I'm doing them. Splashes on my glasses make it hard for me to see. But I figure that's what you get when you get when you exercise in a pool. I just try to move a little further from the splasher. And that's what the ladies beside the pool should do - move out of the splash zone or put up with getting wet.
I have done water aerobics at 3 different clubs in 2 cities, and I have visited even more. There is tension between the water aerobics people and the lap swimmers anywhere they have to share a pool. Its one of the reasons I only take exercise in scheduled water aerobics classes. Any disagreements between the class and the lap swimmers will be handled by club management, usually in favor of the scheduled water aerobics class.
But shouldn't someone swimming for fitness not be splashing but cutting through the water. I remember my sister's swim team coach telling them that if they were splashing they were wasting energy throwing water up instead of pushing through the water.
I encountered a swimmer last summer who felt snowflakey (and strange) in his splashing. I don't normally mind getting splashed, but this was an outdoor pool and I have to wear sunglasses (with waterjogging there's normally very little splashing involved as the swimmers were far enough away and the nearest lane is for fast swimmers who tend to have decent technique). This man however managed to splash everything, his style involved rising an arm as high as it went and then hitting water with it as hard as he could. It looked like it was painful and didn't seem to do much for his speed.
Yeah, but he's not *racing*, so it's not about speed. It's about calorie burn and aerobic load.
Swinging his arms probably did increase his aerobic load (you can do aerobic exercises with your arms only), and it definitely increased his calorie burn.
In fact, the less *efficient* method is probably more *effective* in terms of "wasting energy [calories=energy]." If you want to lose weight, you do want, actually, to "waste" (use up) energy (calories).
