Does Shaving Your Body Actually Help You Swim Faster
This episode of DNews is brought to you byHarry's. Body shaving is a tradition in some sportsâ€¦Maybe I should try it outâ€¦ you knowâ€¦ for sports. Shaving in sports is a big deal, cyclistsdo it to reduce road rash, and cut drag; swimmers do it to feel slicker in the water, and cutdrag, and body builders do itâ€¦ wellâ€¦ to look like thisab. Wowza. Whewâ€¦ Anyway,you can see that speedy sports shave their bodies to CUT DRAG. They're saying, cleaningoff these follicles are going to help you win a race! How do you feel about leg shavingfor swimmersé Mehé! Yeahâ€¦ That's how I felt about it. Kind of just like, okay, go ahead!As long as you feel better! But science says
I might have been playing down a SIGNIFICANTadvantage without knowing it! Drag reduction in speed sports is a huge deal.Cyclists have been doing it for over 100 years. But it wasn't until 1987 that a study wasconducted for Bicycling Magazine by an engineer in a wind tunnel. This study determined thespeed savings were 0.6 percent. Which is just sad. That's SO small. Maybe enough to savefive seconds over an hour at 23 mph (37kph). The results were so piddling, and wind tunnelsso expensive to use, no one ever repeated the experimentâ€¦ until now. A special bicyclespecific wind tunnel wasbuilt by the Specialized cycling company,
and the researchers had free use of it fortesting! Coincidentally, one of their riders had shaved that day, so they figured, whynoté Don't cost nothing, and they found the shaving had reduced the cyclists drag 7 percent!!SEVEN. This meant, a cyclist in a 25 mile (40km), one hour race could save 79secondsby simply shaving their bod! These findings were revolutionary, so to doublecheck theytested five more cyclists. They all saved 5082 seconds over 40 km. WHATé! They alsotested different helmets, different positions and longsleeved racing gear finding significantpower savings here and there. They were shocked. Shaving works, at least in cycling.
In swimming, the jury is still in over itshead. Common wisdom is shaving is mostly psychological. HowStuffWorks says, quot;Razors strip dead skincells off the body in addition to hair, exposing a fresh layer of sensitive skin cells.quot; Becauseof that, the swimmer FEELS better in the water. Though a 1989 study, the only one I couldfind, tested the physiology of shaved and unshaved swimmers while also testing theirdrag reduction. Turns out, physiologically, there were no differences in heart rate, oxygenuse, or lactic acid buildup (which is what makes your muscles burn during exercise).There WERE, however, noticeable drag reductions. Mentally, swimmers probably believe themselvesto be slicker and more powerful in the water,
even without science, but we're here to backthem up. Ladies and dudes, you're totally slicker. Some runners will also get into the habitof body shaving, expecting that over a long race they might reduce drag, but more oftenthe clothing worn will produce more drag than the lack of hair could ever make up for. Soinstead, most Olympic runners today wear computerdesigned, NASA influenced running suits, designed tohelp them glide through the air. Or so they say!.
Best Way to Get Rid of Muscle Knots in Your Back
What is the best way to get rid of muscleknots in your backé I suppose a fancy massage isn't in yourbudget. Not if I want to get one as often as I getback pain like this. You probably get them from using the musclestoo much. The lactic acid is building up to the point that the myofascial points are painful. These knots are in my back, not my face. Myofascial trigger points is the term muscleknots. I don't think I'm overusing the muscles.In fact, I'm out of shape.
Muscle knots may be caused by muscle injuries,such as pulling muscles in your back or overusing them. Conversely, they may be caused by backspasms when you try to use them. If the muscles are overused, they shouldn'tstay tensed up like this. Next time, ramp up your activity over timeinstead of assuming a half hour of hard exercise makes up for not doing anything all day. I need a solution for today, not the nextworkout. Taking a pain reliever like ibuprofen willwork. A hot water jet may help, as would massaging them yourself.
Except that doing so hurts. It hurts less than if you leave it alone ina tensed state for hours. Aside from managing your activity level, howcan I prevent this from happeningé Stay hydrated to flush lactic acid out ofyour system. Get plenty of calcium and potassium to ensure that your muscles have the rightminerals to function. I heard about guys eating bananas before aworkout. Bananas are high in potassium. What else can I doé
When things start to hurt, stop. What happened to no pain no gainé Working too hard one day derails your workoutregimen. You shouldn't work out until it hurts, because then you won't be able towork out over the next few days. I've heard I need to stretch more. Stretch before and after workouts. And neverhunch over even if you aren't working out.
