之前，我写过很多关于不同间歇性训练项目的文章，从单次10分钟强力训练到七分钟、六分钟、四分钟，甚至时间更短的强力训练。

Previously, I have written about a number of different interval programs, involving anywhere from 10 minutes of exhausting intervals in a single session to seven minutes, six, four and even fewer.

运动员们依靠间歇性训练来提高速度，增强力量，不过通常是作为内容更丰富的每周训练项目的一部分——后者还包括时间较长、强度较低的锻炼，比如长跑。

Athletes rely on intervals to improve their speed and power, but generally as part of a broader, weekly training program that also includes prolonged, less-intense workouts, such as long runs.

将传接练习做好，有助于建立起良好的训练情绪与训练节奏。每天的训练项目略有变化，为了让球员在训练中保有挑战性。

Catch drills properly executed can set the mood and tempo of a great practice. We change drills daily to maintain the challenge of executing for the players.
