MODERATE RUNNING AND PLYOMETRIC TRAINING DURING OFF-SEASON DID NOT SHOW A SIGNIFICANT DIFFERENCE ON SOCCER-RELATED HIGH-INTENSITY PERFORMANCES COMPARED WITH NO-TRAINING CONTROLS.

The article discusses research conducted to examine, using the Yo-Yo intermittent recovery level 2 (YoYolR2) test and sprint performance, the effects a reduced training program consisting of either moderate running training or plyometric training had on soccer players. Researchers evaluated 29 players. They found that no players in either training group showed any significant training effects on the YoYolR2 performance or 20-meter sprint times compared with a control group.
