Athletes often are required to travel for sports participation, both for practice and competition. A number of those crossing multiple time zones will develop jet lag disorder with possible negative consequences on their performance. This review will discuss the etiology of jet lag disorder and the techniques that are available to shorten or minimize its effects. This includes both pharmacological and nonpharmacological approaches.

Participants found halogen-based disinfected water significantly less palatable prior to the addition of ascorbic acid. Addition of ascorbic acid to treated water created a beverage of similar preference to distilled water. These results may increase compliance with the use of disinfecting tablets by increasing the palatability of drinking water made potable via addition of ascorbic acid to halogen-based chemical disinfection.

A retrospective analysis was performed on data available from RMRG for 2002 to 2008. Data points collected include number of calls, types of calls, location of calls, victim activity, rescue techniques used, and volunteer hours required. Data were analyzed using descriptive statistics and linear regression models.Results.-Injuries related to hiking and climbing activities were the most common activities requiring a search and rescue response. The types of activities associated with a response did not change significantly over time. The number of calls, types of calls, location of calls, and types of required rescue did not change significantly over the study period. Limited medical data were available for collection.Conclusions.-The prevalence and nature of calls to RMRG did not change over time. These data are valuable for assessing volunteer training program requirements, and for assessing necessary evacuation and medical equipment needs for the near future. Improving medical data collection may be beneficial to better plan for future medical emergencies.
