Transforming,storing and consuming athletic experiences: a coach’s narrative of using a video application

The analysis of sport performance in competitive contexts has become synonymous with the use of a range of software applications and hardware e.g. heart rate monitors and gps systems. With the prevalence of technology in mind, a small but growing corpus of literature has begun to consider this phenomenon and its influence upon the coaching process. This study adds to this literature by detailing the autoethnographic experiences of a case study coach; Derek. A contextualised and richly described narrative account of Derek’s experience of using coaching applications is provided. Analysis of Derek’s narrative suggests that technology can be a useful means by which individuals make sense of their experience. Specifically, (1) technology can be a ‘ready-to-hand’ instrument that enhances the coaching process. Unfortunately, (2) technology may become the only and ‘calculative’ means by which individuals come to understand their performance. In such instances, it is important to note that (3) the videos we use to understand our performance are transformed and incomplete representations of lived athletic experiences. Thus, Derek’s story illustrates how technology can be both an enabler and barrier to athletes who wish to holistically understand their own lived experiences and engage in coach-athlete relationships. The accompanying analysis draws upon concepts from Heideggerian philosophy to add insight into the use of technology within the coaching process. In so doing, the study prompts coaches to critically view their coach-athlete relationships as situated in a wider world which contains, and can be mediated by, technology. In addition, Derek’s story (re)directs researchers and coaching practitioners interested in technology to a useful literature (philosophy of technology) which may further inform their understanding of coach-athlete relationships.

The Persuasive Influence of Nollywood Film in Cultural Transmission: Negotiating Nigerian Culture in a South African Environment

The popularity and viewership of Nollywood films have expanded across African and Western cities especially those with considerable Diaspora population. This study seeks to investigate whether watching Nollywood films is likely to lead to cross-cultural transmission of Nigeria’s cultural heritage to audience members in South Africa. Data for the study were collected using observation and surveys with Likert-type scales involving participants from a South African college. Results show that watching Nollywood films was significant in increasing participants’ knowledge and appreciation of Nigerian culture. Observed patterns indicate that a small portion of participants could mimic or reproduce some common Nigerian expressions and exclamations while a negligible percentage of participants could actually speak a smattering of Igbo, one of Nigeria’s three major languages.
