Eleven moderately trained men (19 to 30 years old) participated in three blind graded maximal treadmill tests for each of two different aspirin doses and a placebo condition. The treatments consisted of the following: an acute dose of 975 mg of aspirin 1 hour prior to exercise; a chronic dose of 975 mg of aspirin 3 times a day for 4 consecutive days; and a placebo of three comstarch‐filled capsules, 3 times a day for 4 consecutive days. Maximal performance was not significantly different among the treatments. However, chronic treatment resulted in significantly higher 5‐minute postexercise lactate levels (p < 0.001), a decrease in time to reach ventilatory threshold (Tvent), and a shorter time to exhaustion (p < 0.01) compared with the acute and placebo treatment Acute treatment also resulted in significantly higher 5‐minute postexercise lactate concent...","PeriodicalId":403174,"journal":{"name":"Sports Medicine, Training and Rehabilitation","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117127909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 3‐day dietary record was collected from seven oligomenorrheic and 10 eumenorrheic female athletes. Fasting blood samples were collected to determine serum estradiol, iron, hemoglobin, hematocrit, and red blood cell levels. There was no signiflcant difference between the groups in either the serum estradiol, iron, albumin, hemoglobin, or hematocrit levels. Most subjects in both groups consumed less than 50% of the recommended daily allowance for iron, zinc, vitamin B6, and estimated safe and adequate daily dietary intake for copper. The results show significant lower body fat in the oligomenorrheic group and a low nutrient intake in both groups. Strenuous exercise plus an inadequate nutrient intake could pose long‐term nutritional problems for athletes.","PeriodicalId":403174,"journal":{"name":"Sports Medicine, Training and Rehabilitation","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121840283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subjects (n = 24) completed a 30‐second Wingate (WG) test, and four 90‐second AGP tests on a cycle ergometer. In the 90‐second cycle ergometer test, several different trials were made with an ergometer resistance set at 2%, 6%, 8%, and 10% of a subject's body weight (BW). Physiological measurements (heart rate, blood pressure, blood lactate concentration) and a psychological measurement (rating of perceived exertion) were made before a test, immediately after it, and after 30 minutes of recovery from the exertion. Statistically, both the WG and AGP tests produced a significant change (p ≤ 0.05) in the physiological and psychological measures. These results were variable but did show that the 6% and 8% AGP tests were the most stressful.

Breathing in cold or dry ambient air causes heat and water loss from the nasal and bronchial mucosa, which has been related to the onset of cough. The relationship between the presence of cough, asthma, and bronchial responsiveness has not been studied properly. This study investigates the prevalence of cough after exercise and its relationship to the presence of bronchial reactivity, asthma, and exercise‐induced symptoms of asthma in a group of elite athletes. The subjects were 130 well‐trained athletes of international category. Forty of the 130 athletes (31%) practiced aquatic sports, and 90 (69%) were involved in nonaquatic sports. The presence of cough was analyzed by a questionnaire, and the presence or absence of asthma or asthma induced by exercise was determined by evaluation of the clinical history, a questionnaire, and a physical examination.

This venue will be the site of opening and closing ceremonies, as well as all of the athletics competition. The measurement periods were during late July and early August, the period corresponding to the planned 1996 Games competition days. Whereas the 1992 data were of a more general nature, and thus preliminary, in 1993, 1994, and 1995 detailed measurements were made at 5‐minute intervals during selected 4‐hour periods. The potentially high temperature, humidity, and radiant heating in Atlanta during the Games period to which athletes, spectators, officials, and media could be exposed warranted such detailed studies. Measurements included dry bulb temperature, wet bulb temperature, and black globe temperature. From these values, the heat stress index temperature was calculated.

Three testers took three counterbalanced BP measures on 30 subjects at rest on land and in water. Generalizability theory was used to determine reliability.
