Heat, Sickle Cell Trait, and a Short Preseason
It is the first week of preseason for a boys soccer team of 34 players. The heat index is 94°F, and the team practices on a turf field with limited shade. The field has one working fountain at the far end. One player has sickle cell trait and a history of cramping; another is five months post-ankle sprain and has not been cleared for full practice; a third missed summer conditioning and is trying to catch up. The coach has 90 minutes, one assistant, and 24 water bottles. State association heat rules require a five-day acclimatization period with no more than one practice per day and no more than three hours per day. The first scrimmage is in six days. The athletic trainer is available only by phone.
1. Design the 90-minute practice with the heat rules, field, and water supply in mind.

The practice should stay within the state acclimatization rules and be modified for a heat index of 94°F on turf. The coach should not use the full 90 minutes for continuous running. A workable plan is:
- 10 minutes: shade meeting, attendance, symptom check, and review of the emergency plan.
- 15 minutes: dynamic warm-up at low intensity with frequent water breaks.
- 20 minutes: technical work in small groups, with one group in shade while the other works.
- 20 minutes: tactical walk-through or low-intensity pattern work, not repeated sprints.
- 10 minutes: water and shade break; check players for cramping, dizziness, or unusual fatigue.
- 10 minutes: cool-down and dismissal.
The coach should move water to the field, not rely only on the far fountain, and should assign the assistant to monitor the back half of the group. The reasoning is that acclimatization is progressive. The first week is not the time for a fitness test. The coach should document the heat index and any modifications.
2. How should the coach manage the player with sickle cell trait, the player recovering from an ankle sprain, and the player who missed summer conditioning?
Read the worked answer
Each athlete needs an individual plan, not a single team standard.
For the player with sickle cell trait: use gradual conditioning, frequent water breaks, and close monitoring. Do not use punishment running or maximal sustained efforts in heat. Stop immediately if the player reports cramping, pain, shortness of breath, or unusual fatigue, and activate emergency care. The coach should confirm that the athlete and family understand the plan and that the athletic trainer is aware.
For the ankle sprain: the player should not participate in full practice until cleared. The coach can assign modified footwork, upper-body work, or observation, but should not let the athlete talk the staff into full drills. Call the athletic trainer for guidance.
For the player who missed summer conditioning: use a gradual return, not extra running to catch up. The reasoning is that heat illness and injury risk rise when an underconditioned athlete is pushed to make up for lost time in the first week. The coach should record the modifications and communicate them to parents.
3. What emergency and communication steps should the coach set up when the athletic trainer is only available by phone?
Read the worked answer
The coach should have a written emergency action plan for the field. Before practice, confirm the exact address or field access point for EMS, the location of the nearest AED, who will call 911, who will meet EMS, and who will supervise the rest of the team. The assistant should know the plan, and a responsible adult should have the athletic trainer's phone number and the parents' emergency contacts.
If a player shows signs of heat illness or sickle cell-related crisis, the coach should cool the athlete, call 911, and contact the athletic trainer by phone. The coach should not send the athlete home alone or wait for the trainer to arrive. For the ankle injury, the coach should use the phone consultation and follow return-to-play guidance rather than clearing the athlete alone.
The reasoning is that a phone-only trainer cannot be the first responder. The coach must organize people, access, and communication before practice. The plan should be reviewed with the team and documented.
