    Well, lets do a rough sum for "girl on top". Lets assume that she weighs 60kg and bobs through a vertical distance of 100mm at a rate of 1Hz. Allowing for the lower legs not being lifted she is moving say 50kg of her body. Work done per stroke is 50kg x 9.81N/kg x 0.1m = 49 Joules. At 1Hz this gives power of 49Watts or 2940 Joules per minute. Now a dietary calorie is 4,180 Joules so she does mechanical work equal to 0.7 calories per minute. The efficiency of human muscle has been measured (in the context of rowing and cycling) at 18% to 26%. (rubbish BTW relative to a modern diesel engine but I digress - its hard to concentrate with the "girl on top" image at work). So allowing for the efficiency she expends between 2.7 and 3.9 calories per minute.

    I would like to do a calculation for the contribution of frictional losses but I'm definitely loosing focus on the maths now.

    Seriously though, that's amazing. 2-3 calories a minute?! I wonder how that compares to other forms of exercise?

    Thanks for the link 8-)=

    It reminded me that I had overlooked the energy lost to the tuned mass dampers aka norks. Got to be good for a couple of calories a minute I guess (fantasise).

    Nicole-it would be interesting if they did an 'equivalent' study comparing a man's heart rate during sex and measured it against his heart rate whilst watching football (Champions League final etc!).

    Back to your original post, for me it does! The gym increases testosterone levels so...

    Just got back from the gym, now feeling very horny, so must be true!

    I think the main situation in which exercise impacts negatively on sex drive is with endurance sports and the training for them. I think this is fairly well documented and the reasons understood.

    I guess long distance cycling would be a case in point, for very obvious reasons!

    I can't wait til they start offering it as an alternative to zumba at the local gym.

    There is not much you can say to that!

    What would the class size be?

    On the other hand, I've just returned from a 5 mile cross-country race, and what I fancied more than anything else was a nice big mug of tea. Having said that, I was cold, muddy and soaking wet from the rain, which probably isn't much of a turn-on for most people.

    You'll be surpised to find out that there have been courses like this in the past - although the ones I've found before have been in the US. I'll have to find links at some point. I know one might be starting up in the next year.

    I really need to work on my sexercise more ;-)
