Answer 1

lol you will loose fat but not loose weight

cuz muscles weigh more than fat

so its OK to be a little heavy

We runners love numbers. Whether it's our pace, finishing times, or resting heart rate, we view figures as a sign of our progress, our accomplishments, our dedication to the sport. So it's no surprise that many of us struggle with one number that increases each year, regardless of how hard we train: our age. But thanks to all the health benefits that running brings, you don't need to sweat each time a candle is added to your cake. "There's a big difference between biological age (how old your body says you are) and chronological age (how old the calendar says you are)," says Steven Hawkins, Ph.D., professor of exercise science at California Lutheran University. "The biological ages of runners are at least 10 years younger than their chronological ones, and the gap widens with time." To ensure that you keep that biological clock fooled, we present a decade-by-decade look at the life span of a runner, filled with advice from doctors, trainers, nutritionists, and amazing runners who define peak performance.

Teens

Decade of Innocence

Ah, youth. Without even trying, you're gaining  speed and recovering instantly. Your body is catapulting into adulthood, and everything from muscle mass, strength, bone density, and VO2 max (the volume of oxygen your body takes in and processes) are on the rise. "A weakness?" says Jeremy Acosta, a 17-year-old cross-country star from Palmdale, California, who lists hills and his final kick as his fortes. "Um, maybe the middle mile of the race?" Yet even a young career can encounter roadblocks. As a freshman, Acosta suffered from Osgood-Schlatter, a common condition that strikes athletes during growth spurts. It causes tenderness just below the knee, and resolves itself once development slows. Acosta ran through it, and when it subsided, he grew into one of his region's top runners.

Your Strengths

Runners in the throes of puberty have superpowers--literally. A British study compared 12 boys and 13 men doing 10 sets of 10-second sprints. The boys sustained their power output better than the men, partly because teens regenerate creatine (a compound that supplies muscles with energy) more quickly than older runners. Also, levels of lactate, the by-product that accompanies intense efforts, are naturally lower in teens. Girls share the same ability to pour on the power--and can sustain it even better than boys. Japanese researchers found that in a series of sprints, teenage girls lost 10 percent less power than boys their age did. That said, as muscle mass piles on, boys have a distinct upper hand--or, in this case, quad. "Boys develop proportionally more muscles than girls do and get the natural power advantage," says Cameron Blimkie, Ph.D., professor of kinesiology at McMaster University in Ontario.   As they develop, running--or other weight-bearing exercise--helps make bones as dense as possible. Blimkie coauthored studies that looked at the bones of female runners, triathletes, cyclists, and swimmers. Runners had the highest bone-mineral density and strength of the four groups.

As fit as you are, your growing body still needs to be handled with care. Bones develop faster than their supporting ligaments and tendons. As a result, joints and muscles can be prone to injury.

Many young female runners who repeatedly miss their periods develop a condition called amenorrhea, says Anne Hoch, D.O., director of the Women's Sports Medicine Program at the Froedtert & the Medical College of Wisconsin. One study determined that 30 to 41 percent of 422 high school– and college-aged female runners had the disorder. Amenorrhea is a red flag for all female runners but is especially troubling for teens in the midst of their bone-building years. (Menstruation releases estrogen, which is vital for calcium absorption.) Experts advise both girls and boys to not take on too much mileage too soon, though there isn't a con--sensus on what exactly "too much" is. Each year, a group of middle school and high school students runs the Los Angeles Marathon with a 90 percent finishing rate and very few medical problems on race day, according to Rudra Sabaratnam, M.D., medical commissioner of the race. Other experts think the marathon is worth waiting for. Lyle Micheli, M.D., director of sports medicine at Children's Hospital Boston, prefers a conservative approach: an upper limit of three miles, five days a week for kids younger than 14, and six miles most days a week for kids 14 to 18.

20s

Inherently stronger and faster than a teenager, you likely run because you love it--and you're good at it. Not because one of your teammates is cute, which is why Nick Symmonds (right), 24, a world-class 800-speedster in Eugene, Oregon, got started. "People typically race their best from their early 20s to their early 30s, when they have a high capacity for work and for recovery," says coach Greg

Increases sexual stamina.

That's why I run.
