The next hot PED? How about electrical currents to the brain?

This is fun. And by “fun” I mean it has all of the makings of a hilarious ethical battle in professional sports at some point.

It’s from Outside Magazine, and describes a new technique that could dramatically enhance athletic performance. It’s called transcranial direct current stimulation, and it’s basically giving your brain a little shock in an effort to bypass the central regulator which most researchers believe we all have. Once that central regulator is down, your brain won’t shut your body down when you’re fatigued. You’ll just keep going.

Here’s how it works:

tDCS is disarmingly—almost disturbingly—simple: you connect a voltage source (a 9-volt battery will do) to two electrodes placed on opposite sides of your head. The precise placement of the electrodes determines which regions of your brain the current flows through. As it passes, the current changes the excitability of the neurons in the affected region, making them slightly easier to trigger (or harder, depending on which direction the current flows). Edwards and Putrino’s primary interest in tDCS is to help patients recover from brain and spinal cord injuries—but “rehab and high-intensity training are not as different as people believe,” Putrino says. “Whether you’re a high-end athlete or a patient fighting locked-in syndrome, you’re dealing with the same limitations of muscle fatigue.”

 

The ethical part of all of this will be fun. As the article notes, it tDCS doesn’t give you more power or performance, really. It just unlocks what you’re capable of doing already, breaking down a barrier. Much in the same way a good trainer can train you to fight through pain and fatigue to get that extra bit of oomph. But because it’s new and weird, I assume people will fall into the old PED arguments rather than actually look at the science of it all and see if it works and what the pros and cons are.

Clayton Kershaw struggles with control, walks six Marlins

Dodgers ace Clayton Kershaw entered Wednesday night’s start against the Marlins without having issued a walk in his previous three starts. In fact, his last walk came on April 3 when he issued a free pass to Paul Goldschmidt with the bases empty and two outs in the bottom of the first inning. All told, Kershaw was on a streak of 26 walk-less innings before he took the mound at home to take on the Marlins.

Kershaw started off Wednesday in character, striking out the side in the first inning. He issued a walk in a tough second inning, but escaped without allowing a run. Kershaw walked two more in the third and again danced out of danger. In the fourth, Kershaw walked Lewis Brinson to load the bases with no outs and — you guessed it — didn’t end up allowing a run. His errant control finally came back to bite him in the fifth when Kershaw issued back-to-back two-out walks, then served up a three-run home run to Miguel Rojas down the left field line. His night was done when he completed the inning. Five innings, three runs, five hits, six walks, seven strikeouts, 112 pitches.

The six walks Kershaw issued over five innings marked his first six-walk outing since April 7, 2010 when he issued six free passes to the Pirates in 4 2/3 innings. The only other time he walked as many was on August 3, 2009 against the Brewers in a four-plus inning outing. Kershaw hasn’t even walked five batters in an outing recently — the last time was September 23, 2012 against the Reds.
