High-intensity interval running is perceived to be more enjoyable than moderate-intensity continuous exercise: implications for exercise adherence

The aim of this study was to objectively quantify ratings of perceived enjoyment using the Physical Activity Enjoyment Scale following high-intensity interval running versus moderate-intensity continuous running. Eight recreationally active men performed two running protocols consisting of high-intensity interval running (6 × 3 min at 90% VO(2max) interspersed with 6 × 3 min active recovery at 50% VO(2max) with a 7-min warm-up and cool down at 70% VO(2max)) or 50 min moderate-intensity continuous running at 70% VO(2max). Ratings of perceived enjoyment after exercise were higher (P < 0.05) following interval running compared with continuous running (88 ± 6 vs. 61 ± 12) despite higher (P < 0.05) ratings of perceived exertion (14 ± 1 vs. 13 ± 1). There was no difference (P < 0.05) in average heart rate (88 ± 3 vs. 87 ± 3% maximum heart rate), average VO(2) (71 ± 6 vs. 73 ± 4%VO(2max)), total VO(2) (162 ± 16 vs. 166 ± 27 L) or energy expenditure (811 ± 83 vs. 832 ± 136 kcal) between protocols. The greater enjoyment associated with high-intensity interval running may be relevant for improving exercise adherence, since running is a low-cost exercise intervention requiring no exercise equipment and similar relative exercise intensities have previously induced health benefits in patient populations.     

Student workshops and neighborhood revitalization

This paper describes an effort to integrate neighborhood technical assistance and student field training through a student workshop. In the spring of 1978, ten students in the Department of Urban and Regional Planning at the University of Illinois at Urbana-Champaign provided technical assistance to the South Austin Realty Association (SARA), a leading neighborhood organization in Chicago. Working in close collaboration with neighborhood leaders, the students produced a report which concluded that South Austin was an excellent location for neighborhood revitalization and that housing rehabilitation was the recommended approach for a demonstration block. The students received academic credit, a positive educational experience, and $72.87 for production costs of the finished report. Neighborhood leaders used the report to help develop plans for a project on the block, then used these plans in a proposal which resulted in a $120,062 contract from the Office of Neighborhood Development of the U.S. Department of Housing and Urban Development. This paper examines the way in which students provided a neighborhood organization with a written plan, assistance in raising funds, and working relations with a university. It also examines the way in which students received substantive knowledge and skills, credentials for future education and careers, and valuable new experiences. It concludes with analysis of the major lessons learned and of the practical problems and questions for educators.This paper is based in part on work done under contract with the South Austin Realty Association to the Bureau of Urban and Regional Planning Research at the University of Illinois at Urbana-Champaign. The views reported are solely those of the authors, not the South Austin Realty Asociation or the University of Illinois.     

A social learning explanation for age-related changes in children's conceptual behavior

A social learning explanation for children's conceptual development is proposed. Recent training research on conservation is discussed, and it is concluded that it fails to support three key assumptions underlying Piaget's theory (a) Children are able to learn to conserve without being “in transition,” (b) nonconservation experiences are successful in promoting developmentally immature cognitive functioning, and (c) there is evidence of inconsistencies in children's cognitive functioning across tasks assessing the same cognitive stage. Two aspects of children's conservation responding are explained according to a social learning position: decalages and the shift from perceptual cues to quantitative cues. This explanation involves consideration of cognitive factors such as prior rule learning as well as impinging social experience.
