The passage and the lecture both discuss about treatment for damaged muscle. The passage claims that the most superior treatment for damaged muscle is to apply heat on the muscle. However, the lecture refutes this. The lecture states putting heat on an injured muscle is bad.

 

First, the passage says that heat is effective because it helps draw blood into the sore muscle. He supports this by stating that by placing a heating pad on the muscle reduces the swelling visibly. On the other hand, the lecture disagrees. The lecture says that applying heat to an aching muscle immediately can encourage the swelling. The lecture suggests that the ice pack should be used to reduce the swelling.

Second, the passage claims that heat can help reduce contraction of injured muscle. The passage says that after using heat, it will be easier for a person to move the muscle without causing further damage. Again, the lecture disagrees. The lecture states that putting heat to an injured muscle can relax the muscle so much that the injured muscle can be underestimated just how bad the injury is. The lecture adds that the muscle can be damaged when it is overly used.

 

To sum up, the passage says that putting heat on a muscle is the best care for injured muscle. However, the lecture claims that applying heat will worsen the damage. The lecture says that an injured muscle requires special care to make it heals properly by taking into account how bad the injury is, not overly soothing them by applying heat to it.
