What is the difference between fast-twitch and slow-twitch muscle fibers? Is it possible to change your ratio of fast-twitch to slow-twitch muscle fibers through training? Fast-twitch muscle fibers support explosive muscle activity (e.g., lifting heavy objects or sprinting short distances), while slow-twitch muscle fibers support activities requiring endurance (e.g., long-distance running). To some degree, we can train our fast-twitch muscles to have more endurance and our slow-twitch muscles to become stronger, but we cannot actually change the ratio of slow-twitch to fast-twitch fibers that we are born with.  Here’s how fast-twitch and slow-twitch muscle fibers impact sports.

What is the SRY gene? What role does the SRY gene play in sports performance? According to David Epstein, the author of The Sports Gene, no single gene has as much of an impact on an athlete’s performance as the SRY gene found on the Y chromosome. The SRY gene also accounts for the predictable and significant differences in sports performance between men and women. Learn about the SRY gene’s function and its implications for atheltic ability.

What are the reasons for the gender performance gap in athletics? Can men and women compete equally in sports? According to David Epstein, the author of The Sports Gene, gender differences in sports are a decisive testament to the power of genes in determining athletic ability. Because athletic ability is at the mercy of genetics, Epstein argues, women are unlikely to surpass men in most sports. Here’s why men and women can’t compete in sports at the same level.

Is speed ability a matter of genetics or training? Which is more important when it comes to speed in sports? While it’s not a physical characteristic, speed is a necessary trait shared by athletes in many sports. Sports and science have yet to determine the exact recipe that makes an athlete fast. Here’s what research has to say on the matter.

What is the average vision of an MLB player? Is 20/20 vision a necessary prerequisite for a career in baseball? Testimony and measurements from optometrists and ophthalmologists reveals that professional baseball players have eyesight that far exceeds the average person’s. This makes sense, as keeping track of the ball is an integral part of the game.
