Soccer. The beautiful game. But physical poetry isn't always as pretty as it looks.

Hi, I'm Dr Greg Wells. Olympic soccer players face an astounding number of physical demands. During a 90 minute match they'll run the equivalent of 10km, often at a full speed sprint. But then, at any time, they have to forget their fatigue and tap into fine motor skills to execute a precise shot. And ideally, score!

Here's how. Soccer players utilize a sequence called the kinetic chain. It's a powerful body snap releasing targeted energy. First, a player plants their foot, then they transfer energy through the body's segments in sequence, until the power reaches the opposite foot. This whips the kicking leg through, unleashing a precise shot that's wickedly fast.

Scoring in soccer is all about precision, and that depends upon your body's ability to supply your muscles with enough energy. Running and sprinting don't leave a lot left over for skills, so how do they stay powered up?

Training stimulates an athlete's DNA to produce more and stronger mitochondria. Mitochondria are tiny structures inside our muscle cells. They're energy powerhouses that fuel every move we make.

Crack the whip...And build the perfect energy factory. That's how you strike...for gold!

足球，优美的比赛，但身体的运作却往往不如外在优美。

我是维尔斯博士。奥运足球选手要面对大量体能要求。90分钟的球赛中，他们要跑相当于10公里，而且往往是全速快跑。但他们必须完全忘却疲劳，并展现出精细的动作技巧去完成射门，最好能够入球。

这是其中原理。足球选手运用一连串称为动力链的机制，那是一个身体开关，可释放目标能量。球员首先要一只脚站稳，随后把能量沿身体各部逐段传送，直到力量到达另一只脚，从而驱动那条腿，踢出速度奇高且准确的一球。

足球的得分关键在于精确，这取决于身体向肌肉提供能量的能力。跑步和冲刺已经消耗大量体力，他们如何保持足够能量？

训练可刺激运动员的DNA产生更多、更强的线粒体。线粒体是肌肉细胞中的微小结构是供应我们每个动作所需能量的工厂。

训练自我，建立完美的能量工厂，这就是你夺金的途径！
