The purpose was to determine the effects of a 12-week, 3-days/week low-impact aerobic dance program on the cardiovascular endurance (CVE) of adults with intellectual disabilities (ID). The experimental group (8 males, 7 females) were adults (M age = 39) receiving employment training at a sheltered workshop. The control group (7 males, 5 females) were adults (M age = 37) affiliated with the same facility but employed offsite. Rockport Fitness Walking Test (RFWT) data were collected five times (pretest, and at 4, 8, 12, and 18 weeks). Repeated measures ANOVAs indicated that the experimental group performed significantly better than the control group on RFWT heart rates on the 8- and 12- week trials and on RFWT walk times at the posttest. Once the 12-week program was over, participants did not exercise. Follow-up measurements at 18 weeks revealed no significant differences between groups.

The purpose was to determine whether publications pertaining to adapted physical activity (APA) pedagogy in the core serials from 1988 to 1998 adhere to library science laws. A bibliometric analysis was conducted on 770 articles in 259 serials selected from 4,130 serials initially identified in four databases (Article First, ERIC, Medline, Sport Discus). Results indicated that 1,720 authors have constructed the early APA pedagogy literature. Of these, only 11 contributed four or more articles. The scatter of APA pedagogy literature over four zones, with 4, 15, 64, and 176 journals in the zones, respectively, supports Bradford’s law of scattering. Price’s law was not supported because most authors contributed only one article. Most pedagogy articles (n = 184) were published in Adapted Physical Activity Quarterly, Medicine and Science in Sport and Exercise, Physician and Sports Medicine, and Palaestra. Graduate education should include exposure to bibliometrics and collaboration with library and information science specialists.

A strategy is presented for temporally aligning ground reaction force and kinematic data. Alignment of these data requires marking both the force and video records at a common event. The strategy uses the information content of the video signal, which is A/D converted along with the ground reaction force analog signals, to accomplish this alignment in time. The vertical blanking pulses in the video signal, which define the start of each video field, can be readily identified, provided the correct A/D sampling rate is selected. Knowledge of the position of these vertical blanking pulses relative to the synchronization pulse makes it possible to precisely align the video and analog data in time. Choosing an A/D sampling rate of 598 Hz would enable video and analog data to be synchronized to within 1/1,196 s. Minimizing temporal alignment error results in greater accuracy and .reliability in calculations used to determine joint kinetics.

The purpose of the current study was to examine the viability of conducting a theory-based physical activity (PA) intervention on men with prostate cancer, and the impact of PA on quality of life (QOL). Participants were 31 men, average age of 67 years, with localized or metastatic prostate cancer undergoing androgen deprivation therapy (ADT). Global QOL, fatigue, and PA measures were conducted at baseline and following the 12-week intervention. An additional follow-up testing was conducted 4 months following the intervention (n = 18). Both moderate and strenuous bouts of exercise, as well as functional capacity, increased significantly from pre- to posttest. Both fatigue severity and resting heart rate decreased significantly at posttest. A trend toward improved global QOL was also noted. It was concluded that a 12-week home-based PA intervention may provide health and QOL benefits for prostate cancer patients undergoing ADT. Practitioners are encouraged to promote PA for prostate cancer survivors.
