Repetition Practice interferes with the ability to learn new information is true.
It is impossible to overstate the value of repetition. In fact, it needs to be emphasized again how important repetition is as a learning tool. It enables the transfer of a conscious skill into the subconscious, freeing up working memory and enabling the acquisition of new skills. Repetition gives kids the practice they need to acquire new skills, so it's a good thing. Repetition helps kids learn faster, builds confidence, and fortifies the neural connections in their brains that support learning. Practice doesn't always make perfect while learning a new skill. Zachariah Reagh and Michael Yassa, neurobiologists at UC Irvine, discovered that while repetition improves the factual content of memories, it can decrease the amount of detail associated with such memories.

During exercises, our muscles needed energy for contractions. The heart pumps more rapidly and more powerfully during this time for a few reasons.
First, more oxygen and nutrients like glucose can be transported to the heart. Muscle cells uses oxygen and glucose for aerobic respiration to generate energy.
Secondly, more carbon dioxide and waste can be transported away from the muscles. Waste products from aerobic respiration includes carbon dioxide or water etc. The faster the heart pumps, the faster the blood gets transported so more waste can be carried away.
Thirdly, lactic acid can be carried away too. When oxygen supply is not enough, the cells undergo anaerobic respiration to generate energy. This type of respiration does not require oxygen, but a waste product called lactic acid is produced. Lactic acid must be carried away from cells because they're harmful. Therefore, the faster the heart pumps, the more lactic acid gets carried away.
Last but not least, heat can be carried away too. Part of the energy generated is turned into heat. Therefore, in order to help us cool down, blood travels fast to carry heat away from the heat generating muscle cells.
