There is a lack of research into the police’s physical defense and control tactics training. Approximately 600 officers in the USA form the research population and their opinions are sought about the defense and control tactics training they receive, their experiences in using these tactics and their interest in alternative techniques and training methods. Results support the idea that in‐service training might be improved. There are high levels of dissatisfaction with the training and there are hints as to how training can be improved.

The purpose of this paper is to analyze the effects of wearing compression pants of varying pressure levels on the wearer’s attention/concentration to investigate the appropriate level of compression for sport performance and confirm whether this methodology is feasible as a means of evaluating sportswear functionality.

After wearing compression pants of varying compression levels, spontaneous potentials were analyzed by calculating the spontaneous electroencephalography (EEG) indices: relative low beta (RLB) power spectrum ((12~15 Hz)/(4~50 Hz)), relative mid beta (RMB) power spectrum ((15~20 Hz)/(4~50 Hz)), and ratio of sensory motor rhythm to theta waves ((12~15 Hz)/(4~8 Hz)). The activation of brain waves was mapped and visualized from EEG data using BioScan-Map (BioBrain Inc., Daejeon, Korea).

The influence of pressure levels on brain waves was confirmed: RLB power, RMB power and RST varied by experimental clothing. CP3, the compression pants that applied moderate pressure (1.57±0.41 kPa), was associated with a relatively higher level of attention/concentration – i.e., the results confirmed that sports compression pants that apply approximately 1.0~2.0 kPa to the area between the thighs and shins are improve attention/concentration. It was further confirmed that EEG is a useful tool for evaluating the psychophysiological effects of functional apparel.

Unlike preceding studies that considered only alpha waves and the effects of clothing on comfort, this study investigated the influence of compression garments on attention/concentration.

The purpose of this paper is to help develop the understanding of the nature of coopetition (collaboration as well as competition) and is set in the context of a Taekwondo organisation.

Interviews were undertaken with 25 instructors in various clubs within New Zealand’s “International Taekwondo” (ITKD) together with 25 students and supplemented with triangulation against secondary data such as websites and media reports.

The findings suggest that coopetition can be seen from various perspectives in order that the organisation as a whole benefits. Specifically, while the ITKD is a not-for-profit firm, individual clubs may compete for revenue from students joining them as opposed to rival clubs. However, clubs collaborate in various way such as once registered, students can train free at rival clubs and resources are to some extent pooled so the ITKD as a whole benefits, e.g. sending competitors overseas and bringing in senior people to undertake a promotion grading.

The contribution is to offer insights into the nature of coopetition at the sports marketing/entrepreneurship interface by suggesting that the potential paradox of collaboration and competition can be explained by considering the benefits to an overall organisation as opposed to individual clubs within it.
