Caffeine Reduces Reaction Time and Improves Performance in Simulated-Contest of Taekwondo

The aim of this study was to investigate the effects of caffeine on reaction time during a specific taekwondo task and athletic performance during a simulated taekwondo contest. Ten taekwondo athletes ingested either 5 mg·kg⁻¹ body mass caffeine or placebo and performed two combats (spaced apart by 20 min). The reaction-time test (five kicks “Bandal Tchagui”) was performed immediately prior to the first combat and immediately after the first and second combats. Caffeine improved reaction time (from 0.42 ± 0.05 to 0.37 ± 0.07 s) only prior to the first combat (P = 0.004). During the first combat, break times during the first two rounds were shorter in caffeine ingestion, followed by higher plasma lactate concentrations compared with placebo (P = 0.029 and 0.014, respectively). During the second combat, skipping-time was reduced, and relative attack times and attack/skipping ratio was increased following ingestion of caffeine during the first two rounds (all P < 0.05). Caffeine resulted in no change in combat intensity parameters between the first and second combat (all P > 0.05), but combat intensity was decreased following placebo (all P < 0.05). In conclusion, caffeine reduced reaction time in non-fatigued conditions and delayed fatigue during successive taekwondo combats.

‘Birthing a Better Future’: A mixed‐methods evaluation of an exhibition on the early years of life

BackgroundOur study aimed to evaluate to what extent Zero2 Expo''s ‘Birthing a Better Future’, a co‐created multimedia exhibition, was effective in raising awareness on the importance of the first 1001 days of life and explore what refinements would help to optimize the impact of future exhibitions.MethodsWe conducted a mixed‐methods evaluation of the exhibition delivered in the John Radcliffe Hospital, Oxford. Through convenience sampling, 14 participants were selected to participate in 12 structured interviews and 19 participants completed a questionnaire. Interviews were thematically analysed alongside quantitative analysis of questionnaire responses through Likert scales.ResultsThe majority (78.6%, n = 11/14) of participants who completed the questionnaire either agreed or strongly agreed that the exhibition raised their awareness about the first 1001 days of life. This was supported by the analysis of interviews. The use of art was found to provoke an emotional engagement from participants. Participants felt that the length of the written pieces and location of the exhibition were important factors for designers to consider in future exhibitions.ConclusionThis study demonstrated that multimedia exhibitions, combining science with art, may be an effective way to raise awareness of public health messages. Engaging with key stakeholders will be an essential step in order to improve future public health exhibitions.Public ContributionWhen designing the study, the public reviewed the study tools, which were refined based on their feedback. At every phase of the study, members of the public who are artists co‐created the exhibition content.     

Mental health promotion for vulnerable African American youth

Fifty-six African American youth between 10–14 years of age participated in a community-based 14-week expressive arts program designed for youth at risk of involvement with the juvenile justice system. Positive and statistically significant findings for pre-post changes in self-control, protective factors, and resilience were found. Difficulty in engaging parents and the strong racial biases of the community appear to have influenced the lack of improvement in self-esteem scores.     

The arts: the real business of education

In the 1990s policy making in education in countries like Australia has been strongly influenced by the depressed economy and prolonged recession. This state of affairs has caused Governments to view education as a means to service the national economic interest. The result is that the arts subjects in the curriculum are clustered together and represent a diminished proportion of a crowded curriculum. Yet major curriculum theorists such as Eisner view the arts as a possible key to educational reform. Also, evidence shows that humans have always used the arts as a means of expression. The authors advocate for the right of children to have experience in each of the creative arts in the curriculum. Three starting points are suggested for including the arts in the basics of education.
