Athletic Training

The role of the athletic trainer is for the care and prevention of athletic injuries. If an athlete is injured on the athletic field, he/she needs to be evaluated by the athletic trainer who will either be on site or available via a walkie talkie. The athletic trainer will evaluate the injury and decide if a doctor's referral is necessary. If the school physician does not need to be summoned, then rehabilitation of the injury will start right away.
Evaluations, treatment and rehabilitation of athletic injuries are performed during or after the academic day. An injured athlete can seek attention from the athletic trainer during their free period, consultation, or X period. No appointment is necessary. If the student does not have a free period, they can come after school.

Pre-season is the best time to prepare the body for a rigorous season. All major strength and power gains should be accomplished during this time. Once the athlete enters his/her sports season, it is then vital to continue to strength train once or twice per week to maintain the pre-season gains. Each athlete will gradually lose what he/she has gained as the in-season progresses; however, in-season lifting will help to slow down this de-conditioning process.
We strive to accomplish these goals throughout our program:
  • Develop strength, power, speed, agility, and durability
  • Design programs based on needs of team, sport, and athlete
  • Increase overall athleticism
  • Set a proper foundation for lifetime health and wellness
  • Decrease sport specific injury
  • Emphasize full body movements and train full range of motion
  • Build discipline and work ethic
  • Prepare each athlete for the next level of athletics
The Al-Rashid Strength and Conditioning Center is open during the academic day. Please contact Coach Rienzo and Coach Wise for assistance with a specialized training program and schedule to meet your goals.
