TEMPERATURE AND PERFORMANCE 4
This second issue of Volume 13 of Coaching Science Abstracts reviews articles concerned with heat, cold, temperature, and fluid regulation in sports. Three previous issues, Volume 3(6), Volume 7(2), and Volume 10(2), also dealt with this topic. The information from those sources as well as that contained in this issue, will yield an extensive knowledge base of recent research in this aspect of sporting performance.
