A Survey of Opinions and Attitudes Toward Exercise Following a 12-month Maintenance Exercise Program for People with COPD

Purpose

To determine the opinions and attitudes toward exercise in people with chronic obstructive pulmonary disease (COPD) who had completed a randomised controlled trial of 12-months maintenance exercise.

Methods

Participants were eligible for recruitment to the maintenance exercise study if they had COPD and had completed an 8-week pulmonary rehabilitation program. They were randomized into an Intervention Group (IG) that consisted of once weekly, supervised hospital-based maintenance exercise plus home exercise for 12 months or a Control Group that undertook unsupervised home maintenance exercise for 12 months. At the end of the 12 months, participants completed a survey consisting of 23 questions using a visual analogue scale (VAS) of 100 mm.

Results

Forty-eight participants completed the 12 month study and 36 participants (75%) completed the survey [IG mean (SD): age 65 (8) years, FEV₁ 58 (20) % predicted; CG: age 66 (8) years, FEV₁ 67 (17) % predicted]. No between group difference was found for the importance of exercise, the benefits of the program or the importance of support from the physiotherapist. However, the IG reported exercising more regularly, having more enjoyment of being involved in the maintenance exercise program, greater benefit in general well-being, and better physical fitness.

Conclusions

At the completion of the 12 month exercise study, the survey results showed that all participants reported positive attitudes towards both supervised and unsupervised maintenance exercise programs, with the IG reporting greater benefits.Key Words: COPD, survey, maintenance exercise program     

Age-related differences in repeated-sprint ability in highly trained youth football players

Abstract

In this study, we investigated the age-related differences in repeated-sprint ability and blood lactate responses in 134 youth football players. Players from the development programme of a professional club were grouped according to their respective under-age team (U-11 to U-18). Following familiarization, the participants performed a repeated-sprint ability test [6 × 30-m sprints 30 s apart, with active recovery (2.0–2.2 m · s^?1) between sprints]. The test variables were total time, percent sprint decrement, and post-test peak lactate concentration. Total time improved from the U-11 to U-15 age groups (range 33.15 ± 1.84 vs. 27.25 ± 0.82 s), whereas no further significant improvements were evident from U-15 to U-18. No significant differences in percent sprint decrement were reported among groups (range 4.0 ± 1.0% to 5.5 ± 2.1%). Post-test peak lactate increased from one age group to the next (range 7.3 ± 1.8 to 12.6 ± 1.6 mmol · l^?1), but remained constant when adjusted for age-related difference in body mass. Peak lactate concentration was moderately correlated with sprint time (r = 0.70, P > 0.001). Our results suggest that performance in repeated-sprint ability improves during maturation of highly trained youth football players, although a plateau occurs from 15 years of age. In contrast to expectations based on previous suggestions, percent sprint decrement during repeated sprints did not deteriorate with age.     

Irreconcilable Differences: Black Teachers’ Lives and K-12 Schools

The mind of a plagiarist

The ease with which material may be ‘copied and pasted’ from the Internet into written work is raising concern in educational institutions, and particularly in those disciplines that use online sources and methods in their curriculum. A case of ‘serial plagiarism’ is discussed, in the work of a graduate student in an online distance education program. The complexity of the student’s thinking is emphasized, and the manner in which the case was handled by the teacher and the university. The use of an online plagiarism‐checking technology (Turnitin.com) and the value of such services are discussed. The case illustrates the importance of explaining the precise nature of plagiarism to students, of providing clear warnings about its consequences and of developing a careful institutional approach to plagiarism detection and prevention.     

The Effects of Goal Origin and Implementation Intentions on Goal Commitment,Effort, and Performance

Self-set goals, selected by students for themselves, have known motivational benefits leading to increased autonomy and intrinsic motivation. In spite of the motivational benefits, students often fail to accomplish self-set goals because they lack the social motivator ascribed to assigned goals. The purpose of this research was to investigate methods of increasing students' commitments to self-set goals using implementation intentions: plans for when, where, and how to work toward a goal. The results of two studies revealed that implementation intentions increased students' performance on self-set goals relative to assigned goals through enhanced goal commitment and effort. Our findings suggest that the positive effects of self-set goals are greater when they are coupled with implementation intentions.     

Moving toward a grand theory of development: in memory of Esther Thelen

This paper is in memory of Esther Thelen, who passed away while President of the Society for Research in Child Development. A survey of Esther Thelen's career reveals a trajectory from early work on simple movements like stepping, to the study of goal-directed reaching, to work on the embodiment of cognition, and, ultimately, to a grand theory of development--dynamic systems theory. Four central concepts emerged during her career: (1) a new emphasis on time; (2) the proposal that behavior is softly assembled from the interaction of multiple subsystems; (3) the embodiment of perception, action, and cognition; and (4) a new respect for individuality. Esther Thelen communicated these ideas to scientists and practitioners alike, so the ultimate benefactors of her work were children.     

The Boehm Test of Basic Concepts as a predictor of academic achievement in grades 2 and 3

Ninety-four second- and third-graders from a suburban New Jersey school who had taken the Boehm Test of Basic Concepts as kindergarteners were given the Stanford Achievement Test, Form W. The obtained grade scores in each subject area as tested by the Stanford were then correlated with the Boehm Test scores. The resulting coefficients indicated a strong association between deficiencies in early concept mastery as measured by the Boehm Test of Basic Concepts and academic achievement in the second and third grades. These results therefore support the use of the Boehm Test of Basic Concepts as an early predictor of school achievement.     

The role of the printed answer in programmed instruction

Using a variety of programmed materials, this series of studies showed that students observed available answers in the program far less than 100% of the time. Answer observing was found to be correlated with student error on the related frame. The view that the printed answer in a program is always a reinforcer for the preceding response(s) is severely questioned.
