Standards for Visual Acuity

Occupational fitness standards for beach lifeguards. Phase 2: the development of an easily administered fitness test.

BACKGROUND No task-based fitness standard currently exists for beach lifeguards (BLGs). AIM To formulate an easily administered fitness test for BLGs based on the physical demands identified in Phase 1 of the project (previous paper). METHODS A range of anthropometric and land- and water-based (swimming pool and flume) fitness assessments were administered to 25 male and female volunteer su...

Beach lifeguards: visual search patterns, detection rates and the influence of experience.

PURPOSE Lifeguard surveillance is critical to any water safety program. This study determined the rates of detection of a 'drowning' individual by beach lifeguards, and whether scanning patterns differed between groups of lifeguards (experienced/less experienced, male/females, surf/non-surf). It was hypothesized that (1) Experienced lifeguards would perform better and produce less fixations of ...

However, I was surprised to find that they recommended widespread clinical use of this chart without any clinical data to confirm its suitability. The statistical argument they use is compelling, but surely a comparison with other methods of acuity testing should be undertaken to confi...
