Abstract

The influence of exercise mode and practice qualities on the stress reduction benefits of exercise was examined. College students in swimming, body conditioning, hatha yoga, fencing, exercise, and lecture-control classes completed the Profile of Mood States and the State Anxiety Inventory before and after class on three occasions. Swimmers had unusually positive initial moods and reported less tension and confusion after swimming only on the first day of testing. Participants in yoga, an anaerobic activity that satisfied three of the four mode requirements, were significantly less anxious, tense, depressed, angry, fatigued, and confused after class than before on all three occasions. Supporting the importance of the four mode characteristics, participants in the exercise control activity of fencing reported improvements only in vigor. A possible influence of practice conditions was observed when members of the body conditioning class reported significant increases in fatigue, but no other mood changes. Results of this study supported the possibility that exercise mode and practice requirements in the proposed taxonomy moderate the stress reduction benefits.  相似文献

This study investigated the effect of a 12-week pedometer-based intervention on daily step counts of 147 older adults randomly assigned to an intervention or wait-list control group (M age = 72.9 years, SD = 8.8). The intervention group significantly increased their daily step counts after 12 weeks (M = 639, SD = 2,239) and continued to significantly increase during a 12-week maintenance period (M = 680, SD = 1,721). The control group exhibited no change during the control period (M =-393, SD = 2,050) but had a significant increase in daily step counts (M = 1,580, SD = 2,305) when enrolled in the intervention. The pedometer-based intervention was effective in increasing participants' daily step counts.  相似文献

Abstract

Retention and relearning of five novel gross motor skills after a long period of no practice were studied. College women were classified into high, average, and low skill groups in a previous experiment, and this classification of 36 of the original subjects was retained in the present retesting study. A high degree of skill was retained after approximately one year of no practice. Relearning to previously attained skill levels was rapid. There were significant differences among classified high, average, and low skill groups in learning, retention, and relearning.  相似文献

Reading comprehension is a challenge for K-12 learners and adults. Nonfiction texts, such as expository texts that inform and explain, are particularly challenging and vital for students?? understanding because of their frequent use in formal schooling (e.g., textbooks) as well as everyday life (e.g., newspapers, magazines, and medical information). The structure strategy is explicit instruction about how to strategically use knowledge about text structures for encoding and retrieval of information from nonfiction and has consistently shown significant improvements in reading comprehension. We present the delivery of the structure strategy using a web-based intelligent tutoring system (ITSS) that has the potential to offer consistent modeling, practice tasks, assessment, and feedback to the learner. Finally, we report on statistically significant findings from a large scale randomized controlled efficacy trial with rural and suburban 4th-grade students using ITSS.  相似文献

Abused children are believed to develop in a harsh environment with minimal contingency of parental responses to their behavior. Seligman proposed that noncontingent caregiving produces helplessness. In this study, helplessness was assessed by measures of persistence and locus of control and by an experimental manipulation which varied contingency feedback. Compared to matched nonabused peers, abused children showed no less persistence in working for rewards, made equivalent use of contingency information to maintain persistence, and assumed equivalent responsibility for success. However, they took less responsibility for failure. Family learning history may render abused children helpless primarily in avoidance of aversive outcomes.  相似文献
