    Size Matters

    Weighing Perfect Performance

    Many consider it a big fitness performance boon to be as light as possible—less drag on bikes, less weight to carry while running or less opponent to go up against in wrestling. But a new book is confirming what some athletes have been privy to for years: skinniest is not always best.

    When you weigh less, you do reduce gravitational pull. In fact, researchers at Hartford Hospital in Connecticut found that each one percent drop in weight corresponds to a one percent improvement in athletic performance. However, dropping the pounds seems to only improve your exercise output up to a certain point. After you lose too many el-bees your body starts almost “eating” your muscle tissue for energy. This makes recovery much more difficult, plus the muscles are not nearly as efficient because they cannot take in as much oxygen as they can at their optimal performance level.

    Interestingly, this acme is different for everyone. A certain percentage of body fat or weight to height ratio cannot predict at which weight each person will be most athletically capable. Even professional athletes must withstand trial and error, the book “Racing Weight: How to Get Lean for Peak Performance,” reports.

    For the average person seeking health, it probably matters little at which weight you perform your absolute best. Anyways, feeling positive about your body’s abilities (even if you’re not Usain Bolt or Lance Armstrong) is more important than setting world records, right?

    Plastic Surgery Surprise

    Before reading on, take a second and guess which elective surgery showed the highest rate of growth in the past year…Perhaps nose jobs? Breast implants? The combo platter?

    It turns out that male breast reduction surgery is tops when it comes to the fastest growing plastic surgery procedures. Why are men worried so much about the “moobs” as some call them? Scientists from the British Association of Plastic Surgery, who have been researching this surgical phenomenon, believe men’s magazines and media images may be to blame.

    While the large majority (about 90 percent) of plastic surgeries performed by members of the Association were for women, the amount of male breast reduction surgeries surged by 80 percent compared to the previous year. It seems that these procedures seem to be recession-proof.

    I understand that this could be an embarrassing situation that some men struggle with, but I would much rather consistently knock out push ups than deal with the recovery pain—not to mention the hospital bill!

    What do you think is the cause for the surge in male breast reduction surgeries? How much pain would you be willing to endure to feel comfortable in your own skin?

    Not just for the ladies…

    Water cooler conversation starter: A nine-year-old girl (yes NINE, so young Associated Press style says I need to spell it out!) gave birth to a healthy baby boy in China late last month. This baby gave birth to a baby on the same day as abstinence-only sex education programs came under fire due to an increase in teen pregnancies. But another report, released days later, found that abstinence-only programs do successfully decrease sexual activity.

    Your thoughts on this touchy subject?

    Walk Wisely

    The Grass is Always Greener…

    On the other side of the street! It’s wise to be conscious of the side of the street you walk or run on when working out around your town. Why you ask? Pollution apparently congregates on one side of the street (at least in areas with buildings around), according to research done at the University of Leeds, UK. Steer clear of the side that is downwind.

    Streets that are very close together can have drastically different amounts of carbon monoxide, this also study found. Save your lungs by simply switching to a side road off of a main thoroughfare. Even though these streets are relatively close together, this small “step” will give you air that has four times less pollution.

    I’ve never considered the pollution much when planning an outdoor route; I usually focus more on making turns with the least traffic and missing the lights. How about you? Do you plan your route to breathe cleaner air? Do you find your workout is harmed by breathing in too much dirty O2?

    Stand (or Sit) Up for Yourself

    Did you know that simply adjusting your posture can increase your confidence?Researchers at Ohio State University found that sitting with your shoulders back and chest open makes you feel more assured of your answers to questions than those who slouch.

    I find myself with rounded shoulders all the time after spending hours (sadly) in front of the computer. This poor posture usually manifests itself in neck and shoulder tension, but I never knew that it could make me less confident! In the past, it seemed as if poor posture was an effect of a lack of confidence, not a cause. This study found that participants weren’t aware that they were more confident than usual. Interesting!

    My freshman high school English teacher kept a sticky note on his computer monitor that simply said “POSTURE!” I might need to do something similar, both for my mental and physical health.

    How’s your posture?

    Water cooler conversation starter: daily caloric consumption in America has obviously gone up since the 1970s, but by how much you ask? Here’s a multiple choice question for you: Calories from what food group have increased the most in the past 40 years?

    A. Added sugars
    B. Dairy products
    C. Protein
    D. Added fats
    E. Flour and cereal grains

    I don’t want to spoil the guesses, so leave your comment then check this out for the answer! (The food group with the greatest caloric increase is listed first in the chart.)
