BlazeSports Institute for Applied Science CDSS Level I Curriculum 1 Injury Prevention for Athletes with Physical Disabilities 2 We would like to thank the following people for their contributions to the content of this presentation: Ben Johnson, EdD, CDSS Professor and Chair Dept. of Physical Education and Exercise Science Brooklyn College City University of New York Jackie McParlane, DO, FACOEP Director - Emergency Medicine Residency Program Botsford Hospital Farmington Hills, MI 3 OBJECTIVES This session will provide basic sport science insights into how injuries occur in sport and physical activity and their prevention through proper planning and training and conditioning programs. The goal is to provide the participant with an understanding of how acute and chronic injuries occur and ultimately can be reduced or even eliminated through sound planning and training. 4 OBJECTIVES 1. The session participant will identify the areas of specialization under the sports medicine umbrella and learn the important components of the coach’s role in the absence of a Certified Athletic Trainer (ATC). 2. The session participant will learn about the relationship of stress and strain on musculoskeletal tissues and how each relates to both acute and chronic injuries. 3. The session participant will learn about the components of fitness and the principles of training and conditioning. 4. The session participant will learn to identify specific aspects of disability sport and physical activities that may contribute to injury. 5 SPORTS MEDICINE The American College of Sports Medicine (ACSM) defines sports medicine as multidisciplinary, including the physiological, biomechanical, psychological, and pathological phenomena associated with exercise and sport. 6 WHAT IS YOUR ROLE?

Any incorrect response indicates concussion and requires removal from the playing field for further medical evaluation 69 CONCUSSIONS • Which field are we at? • Which team are we playing today? • Who is your opponent at present? • Which half/period is it? • How far into the half is it? • Which side scored the last touchdown/goal/point? 70 CONCUSSIONS www.cdc.gov/concussion 71 INJURY PREVENTION STRATEGIES Safe environment Appropriate, well maintained equipment Individualization of training Warning signs of impending injury Warm-up, stretching, and cool-down Appropriate training prescription (mode, duration, frequency, intensity, progression) 72 INJURY PREVENTION STRATEGIES Rest and Recovery FATIGUE FATIGUE FATIGUE The chance of musculoskeletal injury increases significantly when fatigued 73 TAKEAWAYS FROM THIS PRESENTATION Use basic common sense and logical thinking to prevent or reduce injuries! Remember that FORCE leads to MOTION that leads to ENERGY that leads to INJURY The body’s tissues have physiological/biomechanical limitations that, if exceeded, will lead to injury One must limit or reduce force applied to and by the body while also avoiding extreme deformation of body tissues in unnatural positions. Chronic fatigue and overtraining is the enemy of the athlete with or without a disability 74 ADDITIONAL RESOURCES Baechle, T. R., & Earle, R. W. (Eds.). (2008).
