The influence of crank rate on peak oxygen consumption during arm crank ergometry

The aim of this study was to assess the influence of three imposed crank rates on the attainment of peak oxygen consumption ( V O 2peak ) and other physiological responses during incremental arm crank ergometry. Twenty physically active, although non-specifically trained, males volunteered for the study. They completed an exercise protocol using an electrically braked arm ergometer (Lode Angio, Groningen, Netherlands) at crank rates of 60, 70 and 80 rev·min -1 . The order of tests was randomized and they were separated by at least 2 days. Peak V O 2 was significantly higher ( P ? 0.05) at 70 and 80 rev·min -1 than at 60 rev·min -1 . Peak ventilation volume increased as a function of crank rate and was higher ( P ? 0.05) at 80 than at 60 rev·min -1 . Peak heart rate was higher ( P ? 0.05) at 70 and 80 rev·min -1 than at 60 rev·min -1 . Furthermore, 70 and 80 rev·min -1 resulted in an extended test time compared with 60 rev·min -1 . The greater physiological responses observed during the tests at the two faster crank rates might have been the result of a postponement of acute localized neuromuscular fatigue, allowing for more work to be completed. We recommend, therefore, that an imposed crank rate between 70 and 80 rev·min -1 should be used to elicit V O 2peak and other physiological responses in arm crank ergometry.

领导者工作之“三讲”

领导者在工作中要正确地履行其职责,应该自觉做到"三讲"。所谓"三讲"是指讲境界、讲能力、讲良好的个性与习惯。境界是领导者正确履行职责之基础,能力是领导者正确履行职责之依托,而良好的个性与习惯则是领导者正确履行职责的必要条件。     

The work avoidance goal construct: Examining its structure,antecedents, and consequences

Work avoidance goals have been relatively neglected in the literature with most research focusing on mastery and performance goals. The central aim of this study was to examine the structure, antecedents, and consequences of the work avoidance goal construct. Four studies were conducted. Study 1 investigated the construct validity of work avoidance, while Study 2 focused on its antecedents. Using a longitudinal panel design, Study 3 examined the impact of work avoidance—alongside mastery and performance goals—on engagement and achievement, while Study 4 explored its relationship to broader well-being outcomes. Results showed that work avoidance was distinct from mastery and performance goals. Entity theory of intelligence positively predicted work avoidance goal pursuit, while teacher and peer support buffered against it. Pursuing work avoidance goals was found to be associated with less engagement, lower grades, and greater negative affect. The impact of work avoidance on achievement and well-being outcomes seem to be more salient compared to the oft-examined mastery and performance goals. Implications are discussed.

Mothers of Soldiers in Wartime: A National News Narrative

National news media represent mothers of US combat soldiers in the Iraq War as archetypal good mothers, that is, mothers who continue their maternal work even after their children are deployed. However, not all mothers are depicted as the archetypal patriotic mother, i.e., a good mother who is also stoic and silent about the war and her child's role in it. Mothers of soldiers are portrayed as good mothers who sometimes also voice their attitudes about the war effort. The maternal attitudes ranged from complete support for the war to opposition to the war but support for the soldiers. The findings suggest a picture of wartime motherhood that is more nuanced than the historical image of the patriotic mother suggests.
