Module II - Exercise-Associated Collapse

 

Overview

In this module, the individual will learn how to manage episodes of exercise-associated collapse (EAC) on the race course. He/she will learn best-practice guidelines and preventive medical plans for healthcare professionals, as well as definitions, mechanisms, and symptoms of SCA. The final portion of the module introduces the use of algorithms for informed decision-making.

Learning Objectives

By the end of this module, the learner will know how to differentiate conditions that result in collapse and create a strategy to deploy medical staff along the race course based on data showing common collapse points.

Key Pedagogical Points 

 
  • EAC is the most common cause of collapse in endurance athletes.
  • EAC is a type of postural hypotension related to pooling of the blood in the legs once the calf muscles have stopped working.
  • If a collapse happens during exercise, this is unlikely to be an EAC and may indicate a more severe cause.
  • Runners should be encouraged to keep walking through the finish area, as the abrupt ceasing of exercise heightens the risk of EAC.
  • Elevation of the legs above the level of the heart will help with recovery.
