Clean and jerk意思
"Clean and jerk" is a term used in weightlifting, specifically in the sport of Olympic weightlifting. It refers to one of the two competition lifts, the other being the snatch. The clean and jerk consists of two parts: the clean and the jerk.
-
Clean: The athlete lifts the barbell from the floor to a position at the front of the shoulders, with the arms straight and the elbows locked. This involves a squatting movement to get under the bar and then standing up with it.
-
Jerk: The athlete then lifts the barbell overhead in one smooth motion, typically by dipping and then extending the legs and arms to lock out the arms overhead.
The clean and jerk is a test of explosive strength, technique, and athleticism. In competition, athletes are scored on the total weight lifted, which is the sum of the highest successful snatch and the highest successful clean and jerk. The clean and jerk is a staple exercise in many strength and conditioning programs, not just for Olympic lifters but also for athletes in various sports who seek to improve their power and overall strength.
