Aim was to identify critical load (CL) in young and elderly apparently healthy male cohorts. To contrast the metabolic, cardiovascular and perceptual responses on CL according to age. We evaluated 12 young (23 ± 3 years) and 10 elderly (70 ± 2 years) apparently healthy active males, who underwent: (1) 1 repetition maximum (1RM) test on a 45° Leg Press; (2) on different days, three high-intensity resistance exercise constant load tests (60%, 75% and 90% 1RM) until fatigue (Tlim). Absolute values of both the CL asymptote and curvature constant (kg) were significantly lower in elderly subjects (P < 0.05). In contrast, elderly subjects demonstrated a significantly higher number of repetitions at CL when compared with young subjects (P < 0.05). As expected, oxygen uptake (VO2) and heart rate (HR) during maximal aerobic exercise testing were significantly reduced in older subjects. However, percent-predicted aerobic capacity were higher in older subjects (P < 0.05). In addition, blood lactate ([La?]) corrected to Tlim and rating of perceived exertion values were greater in younger subjects at all intensities (P < 0.05). These findings, despite reduced force production in older subjects, endurance-related parameters are well preserved according to age-adjusted percent-predicted values in apparently healthy males. 相似文献

Children, as well as adults, can be handicapped when taking a standardized test because of an unfamiliarity with the test format or with the requirements of the testing situation. This review presents a critical analysis of the skills required for test-taking, the training of test-taking skills, and the experimental evidence on the training. Based on the recommendations of psychologists such as Thorndike, Cronbach, and McClelland, practical classroom strategies for test-taking are discussed. Cautions on the pitfalls of training test-taking skills on questionable dimensions, such as on test item content, are also discussed. The review concludes with recommendations for a task-specific instructional unit which trains the necessary skills for test-taking to assure that the score on the test is an accurate measurement of the skill being assessed. 相似文献
