Ensuring Rest Time for Injured Athletes A 2014 study by the journal Medicine & Science in Sports & Exercise found that players who return to sports before the brain recovers from a concussion increase the likelihood of having long-term health problems. Injured athletes need physical rest and cognitive rest. Teachers need to make adjustments for an athlete who has had a concussion by limiting their cognitive challenges. Research has shown that athletes should not return to physical activities until their symptoms have returned to normal baseline levels. Athletes often feel frustrated, sad, and even angry because they cannot return to sports right away. It is important for coaches, parents, and medical professionals to offer support to these athletes.

Which two types of support could be added to the section "Ensuring Rest Time for Injured Athletes" to strengthen the overall claim?

1. details related to the challenge of ensuring proper rest for athletes in highly competitive sports
2. an explanation of how proper support decreases an athlete's likelihood of returning to the sport too soon
3. a description of the signs that an athlete is ready for activity again
4. an example of an athlete who chose to leave sports to avoid the risk of injury
5. a comparison of the differing approaches to concussion treatment for high school and professional athletes
