A new feature starting from this issue is pre-publication of draft articles for further peer review. We have also reformatted some earlier articles into a back issue of Sportscience. %0 Journal Article %9 News %A Hopkins, W.G. %T Polarized training and hypoxic muscles?

Email: will.hopkins=AT=otago.ac.nz %X Training: elite endurance athletes avoid the lactate threshold; explosive training enhanced speed and endurance. Altitude: using a nitrogen house to live high and train low increased maximum oxygen uptake. Nutrition: carbohydrate loading, high-carbohydrate pre-exercise meals, and drinks containing carbohydrate or extra salt enhanced endurance performance; high-fat diets might enhance ultra-endurance under some conditions. Ergogenic and Anabolic Supplements: most studies showed positive effects of creatine on repeated sprints, some showed anabolic effects with continued use, and one showed increased cramps in dehydrating exercise; hydroxymethylbutyrate and a zinc- magnesium supplement appeared to be anabolic, but dehydroepiandrosterone wasn't; ginseng and pyruvate supplements didn't work, but beta-carotene might enhance endurance. Lab Tests: be suspicious of data from your metabolic cart; skinfolds are better than underwater weighing; what's the best lactate test? Miscellaneous: biomechanical studies were mostly descriptive; an initial slow pace may be important in endurance events; the ACE gene isn't a performance gene after all; researchers need confidence limits.

Email: natalie.harlan=AT=nau.edu. %X The High Altitude Sports Training Complex’s Symposium of Sports Science was instituted in 1998 in an effort to bridge the gap between science and coaching in the field of altitude training. This year’s event included presentations on the theory of living high and training low and a pilot study of simulated altitude. The keynote presentation highlighted additional considerations for athletes training at altitude, along with and possible reasons for non- response or negative responses to altitude training. These included unstable health at the start of altitude exposure, too much anaerobic work, and poor nutrition. A printed transcript of the presentations is available. %K acclimatization, elite athletes, hypoxia %0 Journal Article %9 News %A Stewart, A.M. %T Amino acids and athletic performance: a mini conference in Oxford %J Sportsci %B Sportscience %V 3 %N 2 %P sportsci.org/jour/9902/ams.html, 1999 (1108 words) %D 1999 %O Scottish Institute of Sports Medicine and Sports Science, University of Strathclyde, Glasgow, G13 1PP, Scotland. Email: andy.stewart=AT=strath.ac.uk %X Supplementing with glutamine reduces the risk of infections, and supplementing with branched chain amino acids benefits physical and mental performance in long endurance events, according to presenters at this one-day conference. One speaker argued that creatine supplementation was not ergogenic in competitions. A panel suggested renaming overtraining as the underperformance syndrome, but some members of the audience preferred underrecovery. %K branched-chain amino acids, creatine, glutamine, overtraining, supplementation %0 Journal Article %9 News %A Daley, K. %T Moving Together: Newsletter 24 %J Sportsci %B Sportscience %V 3 %N 2 %P sportsci.org/jour/9901/mt24.html %D 1999 %O Department of Exercise and Sport Sciences, Maharishi University of Management, Fairfield, Iowa, USA 52557.
