Effect of induced alkalosis on swimming time trials.   总被引:1,自引:0,他引:1  
Previous studies have shown that sodium bicarbonate ingestion prior to exercise may improve performance during repeated (interval) bouts. To examine the practical implications of such findings, seven collegiate swimmers participated in simulated swim competitions of multiple events following sodium bicarbonate (B) ingestion, placebo (P) ingestion and control (C--no ingestion) treatments. Each swimmer reported to the laboratory 1 h prior to the simulated competitions (72 h apart) and was randomly assigned to one of the three experimental treatments. Competition consisted of one relay (100 yards; 91.4 m) and two individual (200 yards; 182.8 m) swimming events with 20 min rest between events. Analysis of variance (ANOVA) with repeated measures revealed no significant differences in performance times as a result of the three treatments (P greater than 0.05). The results suggest that sodium bicarbonate ingestion prior to swim competition consisting of significant rest intervals between events is not an ergogenic procedure.  相似文献

Recognizing the role that physical activity has in assisting young children attain desired objectives, early childhood educators should continually be investigating avenues for involving children in movement experiences. Caregivers should be aware that for the child, movement is one of the most utilized vehicles of nonverbal interaction and expression. All children enjoy physical activity. Playing makes a child happy.Wayne Eastman is on the faculty of the Fisher Institute of Applied Arts and Technology (Early Childhood Education), Corner Brook, Newfoundland, Canada.  相似文献

Previous research has found conflicting evidence regarding how early children can effectively use separate answer sheets with achievement tests. This study looked at the effects of separate answer sheets on the California Achievement Test (CAT) scores of third, fourth, and fifth graders. The Mathematics Computation and the Reading Comprehension subtests of the CAT were used. Seventy-one classrooms were randomly assigned to have students record their answers on either: (a) their test booklets, (b) separate answer sheets, or (c) separate answer sheets after being given training in the use of separate answer sheets. The results were consistent across both subtests and grades; no response mode treatment effect was found. Further, no evidence of a treatment by ability interaction was found, which was contrary to previously reported research. The results of this study suggest that students can, as early as grade three, effectively use separate answer sheets without prior training.  相似文献
