We present here a spreadsheet using the principles of partitional calorimetry to estimate how a given environmental condition and/or clothing ensemble affects the ability of the body to gain or lose heat during prolonged exercise.,%http://sportsci.org/jour/0003/ka.html'~wSchool of Exercise and Sport Science, University of Sydney, Sydney, NSW 2141, Australia.

Lack of regulation of quality control and labeling of products in the supplement industry makes it impossible to identify supplements and sports foods that are risk free. Incentives or punishments for the supplement industry to improve manufacturing processes are therefore needed. Meanwhile sports authorities place the responsibility for a positive test with the athlete, necessitating better education of athletes, coaches and support staff.,&http://sportsci.org/jour/0003/lmb.html'~wDepartment of Sports Nutrition, Australian Institute of Sport, Belconnen 2616, Australia.

The impact factor is therefore an objective measure of influence of journals in a discipline. The four journals with the highest impact factors in sport and exercise science are Exercise and Immunology Reviews (impact factor 2.9), American Journal of Sports Medicine (2.3), Medicine and Science in Sports and Exercise (2.1), and Journal of Applied Physiology (2.1). All other journals in this discipline have impact factors of 1.5 or less. Researchers concerned about their career development should take impact factors into account before submitting an article for publication.,&http://sportsci.org/jour/0003/wgh.html'Department of Physiology and School of Physical Education, University of Otago, Dunedin, New Zealand 9001.

However, weight training based on high-intensity low-repetition sets is likely to improve the performance of most gymnasts by increasing strength with minimal muscle hypertrophy.,&http://sportsci.org/jour/0003/was.html' Department of Kinesiology, California Lutheran University, Thousand Oaks, CA 91360; Department of Physical Education, Health and Recreation, Eastern Washington University, Cheney, WA 99004; University of Rennes, Rennes, France.
