In endurance sports such as cycling and running, hitting the wall or the bonk describes a condition caused by the depletion of glycogen stores in the liver and muscles, which manifests itself by sudden fatigue and loss of energy. Milder instances can be remedied by brief rest and the ingestion of food or drinks containing carbohydrates. The condition can usually be avoided by ensuring that glycogen levels are high when the exercise begins, maintaining glucose levels during exercise by eating or drinking carbohydrate-rich substances, or by reducing exercise intensity.作者: stunyap 時間: 2013-3-6 21:41
不太明白這個例子，為何比較兩個唔同的跑手？一個跑2：0X，一個跑2：2X，兩人體能都不同。如是同一人，沒有補給的話，跑快會早一點撞牆，跑慢會遲一點撞牆。樓上位師兄的回覆亦有說："The condition can usually be avoided by ... reducing exercise intensity"作者: tango 時間: 2013-3-7 08:51
係咪真唔會見到至top 跑手撞牆，或者掉轉黎講，俾你見到佢撞牆果一場，佢唔係至top 果個
(重申，我仲未界定到乜叫撞牆)
