3-min all-out effort on cycle ergometer is valid to estimate the anaerobic capacity by measurement of blood lactate and excess post-exercise oxygen consumption

The purpose of this study was to investigate the use of a single 3-min all-out maximal effort to estimate anaerobic capacity (AC) through the lactate and excess post-exercise oxygen consumption (EPOC) response methods (AC_{[La^?]+EPOCfast}) on a cycle ergometer. Eleven physically active men (age?=?28.1?±?4.0?yrs, height?=?175.1?±?4.2?cm, body mass?=?74.8?±?11.9?kg and ?O_2max?=?40.7?±?7.3?mL?kg^?1?min^?1), participated in the study and performed: i) five submaximal efforts, ii) a supramaximal effort at 115% of intensity of ?O_2max, and iii) a 3-min all-out maximal effort. Anaerobic capacity was estimated using the supramaximal effort through conventional maximal accumulated oxygen deficit (MAOD) and also through the sum of oxygen equivalents from the glycolytic (fast component of excess post-exercise oxygen consumption) and phosphagen pathways (blood lactate accumulation) (AC_{[La^?]+EPOCfast}), while during the 3-min all-out maximal effort the anaerobic capacity was estimated using the AC_{[La^?]+EPOCfast} procedure. There were no significant differences between the three methods (p?>?0.05). Additionally, the anaerobic capacity estimated during the 3-min all-out effort was significantly correlated with the MAOD (r?=?0.74; p?=?0.009) and AC_{[La^?]+EPOCfast} methods (r?=?0.65; p?=?0.029). Therefore, it is possible to conclude that the 3-min all-out effort is valid to estimate anaerobic capacity in physically active men during a single cycle ergometer effort.     

Useful terms in psychoeducational reports: A survey of students,teachers, and psychologists

The usefulness of terminology in psychoeducational reports is examined. Students, teachers, and psychology interns rated the usefulness of 25 terms frequently found in reports. Psychology interns also rated each term on the frequency with which they used it in their own reports. Significant differences were found in the usefulness ratings of the terms, depending on major, category, and whether or not the rater had taken a special education course. Special education majors were found to be more comfortable with technical terms than were students who had prepared to be regular classroom teachers or students in other majors. Findings suggest that it is necessary to use clear, unambiguous terms in reports, and to explain more technical terms in context.     

A comparison of regular program and vocational program junior high school students on affective dimensions

The hypothesis that young adolescents in vocational education programs would differ from young adolescents in a regular program along several affective dimensions was examined. The Today Form of the Multiple Affect Adjective Check List (MAACL) was administered twice during the school year to 111 students in a vocational program and to 50 students in regular classrooms. Dimensions of Anxiety, Depression, and Hostility were examined. Significant main effects for all three dimensions were noted for school program (regular vs. CVAE) and for grade (seventh vs. eighth). Students in the vocational program and those in seventh grade scored higher on Anxiety, Depression, and Hostility. These differences persisted across time, with the exception of Depression, for which there was a significant interaction between time (pretest vs. posttest) and school program (regular vs. CVAE), with regular students reporting increased depression at the second testing.     

Locus of control and reading attitude

The relationships between three measures of locus of control and eight dimensions of reading attitude were investigated for a sample of 431 inner-city children. The sample included the intermediate grade children enrolled in the 20 regular classrooms of the three elementary schools from the Columbus, Ohio, Public Schools. Correlation coefficients were computed between locus of control scores and the eight dimensions of reading attitude. Reading Anxiety showed a significant relationship with the I- score. This finding suggests that inner-city children who are willing to accept personal responsibility for negative events in their lives also tend to experience more anxiety about their reading. The other seven dimensions of reading attitude were not significantly related to internality scores.     

Broadway productions and the value of a Tony Award

This article investigates the effect of a Tony nomination or win on the demand facing a Broadway production using a panel of weekly revenues for Broadway productions from 1996 to 2007. Our results indicate that the effect of a nomination or win is positive in the week of the announcement and gradually increases in successive weeks, presumably due to publicity and word-of-mouth. Winners experience an increase in demand as late as 1 year later when awards are publicized for the following season. Moreover, nominees that do not win the award are penalized heavily in the weeks following the Award announcements. We find that winning a Tony Award increases a production’s revenues by 12% in the week immediately following the Awards.

Correlations between serum and salivary hormonal concentrations in response to resistance exercise

The aim of present study was to examine the relationships between serum and salivary values of free testosterone, dehydroepiandrosterone, and cortisol before and after a session of resistance exercise. Twenty-eight healthy men (mean age 40 years, s = 4) participated in the present study. Serum and salivary samples were collected at rest and after a multiple-sets resistance exercise protocol, of approximately 25 minutes duration. Concentrations of free testosterone, dehydroepiandrosterone, and cortisol were measured using radioimmunoassay kits. No significant correlation was observed between serum free testosterone and salivary testosterone (r = 0.22 to 0.26, P > 0.05). Serum cortisol was significantly correlated with salivary cortisol before (r = 0.52, P = 0.005) and after (r = 0.62, P = 0.001) the exercise protocol. Serum and salivary concentrations of dehydroepiandrosterone were significantly correlated before (r = 0.68, P < 0.001) and after (r = 0.7, P < 0.001) exercise. The results of the present study suggest that even under exercise conditions, the salivary values of cortisol and dehydroepiandrosterone can reflect the behaviour of these hormones in blood. However, further studies are necessary to verify if salivary testosterone reflects the behaviour of serum free testosterone during resistance exercise.
