Ji argued the replacement is not a "compromise", and that the energy consumed in the 20-meter shuttle run is exactly the same amount as that of the long-distance run. "It doesn't mean the long run will be left out. On the contrary, it will still work as an important exercise item for students. Students are extremely encouraged to participate in various exercises," Ji said.
The long distance runs have proves a nightmare for many students. Physical education scores in junior high school are counted into students' total scores for graduation, which means the long-run scores will affect the level of the high school students will get to attend.
"The long-distance run was pure hell. I would have some chocolates before the run. Especially when my grades were related to the entrance examination, I would become cautious," said Cao Yue, a female student.
Meanwhile, some experts doubt that the shuttle run can guarantee students' safety and health. Lu Yuanzhen, professor of the school of physical education and sports science at South China Normal University, called for more prudent consideration before implementing the 20-meter shuttle run.
Questioning whether cardiopulmonary function can be measured through the shuttle run, Lu said the shuttle run cannot reduce the potential harm to students such as passing out and sudden death. Besides, the sudden stops and turning around during the shuttle run will hurt students' knees.
But Ji defended the move. "Compared with years ago, Chinese students are becoming weaker in fitness, such as strength and physical endurance. The reason is from their heavy academic burden. They are forced to pay more attention to academic scores. They have little time to sleep, let alone exercise," Ji said.
