How much does body weight effect swimming speed?

This has been something I've wondered the last few years. I used to be a college swimmer, fit and trim, but the 10 years since then I've drank my fair share of beer and ate plenty of cheeseburgers. Just curious what peoples' take is on how much the extra baggage really effects swim races. I don't really fit the swimmer mold anymore. I'm 31, 6'2", and 270lbs with a huge beer gut. I got some strange looks since the meet i was in recently was a USAS meet and I outweighed my competition by 100lbs in many cases. My first race in about 5 years i went 23.4 in the 50y free. I didn't expect to be that fast at this weight but at the same time I almost wonder if the added intertia is helping me more on the start and turns. Followed it up with a low 52 in the 100y free but I had a horrible reaction on the start and incorrect pacing. I think if i raced again today that'd be deep in the 51 range. For reference, typical non-taper times for me in college were in the low-mid 22 range at just a tick over 200lbs but I was obviously a lot stronger, younger, and doing a TON more yards at the time, that's why it makes me wonder just how much the weight is actually holding me back. How much time do you think I stand to drop if i were 50lbs lighter? Could it be a measurable difference or something just slight? I guess I ask that to see if it'd be worth my while to drop that much weight quickly by dieting in addition to the swimming i'm doing. I don't really like dieting, and i generally eat what I want, when i want. Not gorging myself at every meal doesn't really seem to fit into my lifestyle :blush: Anyone have a similar story? "I dropped XX lbs and went XX seconds faster because of it." Maybe it's an immeasurable, but I thought I'd ask for opinion anyway. I'm hoping it doesn't turn into a "to diet or not to diet" discussion though.

  • I am 56, 6"2 and weigh about 207. I was up to 220 but I made a few adjustments (including leaving a high pressure job) and dropped over 10 lbs. When I was in my early thirties I weighed around 165. Some of the added weight was muscle mass from weight training, but there was also mid section fat. My point is that nearly everyone gains weight as they get older. I also ate what I wanted, when I wanted and how much I wanted. No more. That is not a sustainable lifestyle. My goal is now to get below 200 without losing muscle mass.So if you are 270 at your age you are headed for a real health problem and you have to make a change now. And this has nothing to do with how fast you swim - it's about your health. Swimming is not the optimal activity for losing weight. But for most of us that is irrelevant, because we like to swim. Swimmers on all levels carry more body fat than other athletes at that level. Some fat is advantageous in swimming. And we have all seen really great swimmers at the pool who are also fat. I can't imagine an overweight runner. There are a number of reasons for this but I believe the main reason is that swimming is more more of a skill and technique sport than running. Also, the effect of gravity is much less in the water. What I am saying is that IMHO you may very well be able to swim fast for short distances but what about longer distances? I think that the longer you swim, the more your "extra baggage" will slow you down.
