For Western tourists Africa embodies the Romantic ideal of 'nature', where they go to have adventures in the game parks and encounters with colourful cultures and picturesque people. In the long list from slavery to colonialism and from liberation to globalisation, international tourism is one of the latest global dynamics engaging the people on the continent, but the agency of the receiving partners is much larger than it was in the colonies. The differences stand out in what constitutes the heart of this book, the encounter in the field between 'hosts' and 'guests'

The functional fitness training program CrossFit® is experiencing fast-growing and widespread popularity with day-to-day varying 'Workouts of the Day' (WOD). Even among tactical athletes, the training program is widely applied. Nevertheless, there is a lack of data on which parameters influence CrossFit® performance. For this reason, the purpose of this study is to conduct a systematic review of the existing literature to identify and summarize predictors of CrossFit® performance and performance enhancement. In accordance with the PRISMA guidelines, a systematic search of the following databases was conducted in April 2022: PubMed, SPORTDiscus, Scopus, and Web of Science. Using the keyword 'CrossFit', 1264 entries are found, and 21 articles are included based on the eligibility criteria. In summary, the studies show conflicting results, and no specific key parameter was found that predicts CrossFit® performance regardless of the type of WOD. In detail, the findings indicate that physiological parameters (in particular, body composition) and high-level competitive experience have a more consistent influence than specific performance variables. Nevertheless, in one-third of the studies, high total body strength (i.e., CrossFit® Total performance) and trunk strength (i.e., back squat performance) correlate with higher workout scores. For the first time, this review presents a summary of performance determinants in CrossFit®. From this, a guiding principle for training strategies may be derived, suggesting that a focus on body composition, body strength, and competition experience may be recommended for CrossFit® performance prediction and performance enhancement.

In the trend sport CrossFit®, international competition is held at the CrossFit® Games, known worldwide as the definitive fitness test. Since American athletes are the best in the world regarding CrossFit®, there might be influencing factors on international competition performance. Here, we characterize the benchmark performance profile of American and German CrossFit® athletes (n = 162). To collect the common benchmark performance by questionnaire, 66 male and 96 female CrossFit® athletes (32.6 ± 8.2 years) participated in our survey in both nations. By comparing the individual performance variables, only a significant difference in total power lift performance by males was identified between the nations (p = 0.034). No other significant differences were found in the Olympic lift, running, or the "Girl" Workout of the Day (Fran, Grace, Helen) performance. Very large to extremely large (r = 0.79–0.99, p < 0.01) positive correlations were found between the power lift and Olympic lift variables. Further linear regression analysis predicted the influence of back squat performance on performance in the Olympic lifts, snatch (R2 = 0.76) and clean and jerk (R2 = 0.84). Our results suggested a dominant role of back squat performance in the assessment of physical fitness of CrossFit® athletes.

Tourism is important for Africa: international tourist arrivals to Africa continue to grow, income from tourism is crucial to national economies, and tourism investments are considered among the most profitable. This edited volume deals with the interaction of local communities with tourists coming into their areas and villages. Based upon a common theoretical approach, fourteen cases of African tourism are discussed which involve direct contact between 'hosts' and 'guests'. The viewpoint throughout is from the side of the locals, establishing how the processes of interaction shape each small scale destination. Crucial in Africa is the fact that the large majority of tourism is game oriented and the interaction between locals and visitors is very much 'tainted' by this fact. Central is the notion of the tourist bubble - the infrastructure that is generated locally (and internationally) for hosting tourists, as it is this institutional interface that tends to impact on the local society and culture, not the tourists themselves directly. The examples come from all over Africa, from the Sahara to the Eastern Cape, and from Kenya to Ghana. All contributions are based upon original fieldwork. Walter van Beek is professor of anthropology at Tilburg University and Senior Researcher at the African Studies Centre, Leiden; Annette Schmidt is curator of the African department at the National Museum of Ethnology in Leiden, and is an archaeologist with a long experience in cultural management projects

Purpose The lack of in-person schooling and participation in structured recreation activities during the COVID-19 pandemic may have altered children's movement behaviors. This study assessed changes in children's self-reported in school and out of school physical activity, sedentary behavior, and play before and during the pandemic. Design A repeated cross-sectional online survey was administered in February 2020 (pre-pandemic, in-person) and 2021 (during pandemic, remote). Setting Children attended an urban public school district in Phoenix (AZ) serving a low-income population. Subjects Students in grades 4–8 completed the survey in 2020 ( n = 253, 62% response rate) and 2021 ( n = 261, 77% response rate). Measures The survey included items from the Youth Activity Profile and three additional questions about play. Analysis Differences in mean scores and mean scores by gender were analyzed using one-way and two-way ANOVAs. Results Students reported less physical activity during remote recess in 2021 (M = 3.42, SD = .80 v. M = 2.99, SD = .86, p < .05). Physical activity outside of school decreased during the pandemic (M = 2.76, SD = 1.26 v. M = 2.53, SD = 1.18, p < .05). Most students (55%) reported playing less during the pandemic, but playing in new ways (67%). Conclusion Children may benefit from interventions to counter reduced movement experienced during the pandemic, particularly in under-resourced areas.

Fragestellung: Es besteht ein Bedarf nach effektiven, jugendspezifischen Rauchstopp-Angeboten. Inwiefern kann das schulbasierte Rauchstopp-Programm losgelöst die Zielgruppe erreichen und bundesweit umgesetzt werden? Methodik: Die Studie hat ein Ein-Gruppen-Prä-Post-Design und wertet Daten von 2 754 Jugendlichen aus 24 meist Haupt- und Realschulen sowie von 22 Kursleitungen und 139 Kursteilnehmenden aus. Rekrutierungsrate, Teilnehmermerkmale, Bewertung und Aufhörrate werden nach Schultyp und Geschlecht verglichen. Ergebnisse: An 73,3 % der anvisierten 30 Schulen (n = 22) fand mindestens ein Kurs statt, 18,9 % der rauchenden bzw. 48,8 % der aufhörwilligen rauchenden Jugendlichen wurden erreicht (n = 139). Losgelöst wurde von Teilnehmenden und Kursleitungen sehr positiv beurteilt, eine Haltequote von 72 % wurde erreicht (n = 101). Während des Kurses hören 30,2 % der Jugendlichen (n = 42) mit dem Rauchen auf (intention-to-treat-Analyse), weitere 37,7 % (n = 51) reduzierten die Konsummenge um die Hälfte. Am Ende der Nachbetreuungsphase von vier Wochen waren 24,4 % (n = 34) rauchfrei. Akzeptanz und Aufhörrate differierten nicht zwischen Schultyp oder Geschlecht. Schlussfolgerungen: Die Studie erbrachte Hinweise darauf, dass mit losgelöst ein Rauchstopp-Programm zur Verfügung steht, das gut implementierbar ist, rauchende Jugendliche erreicht und sowohl von ihnen als auch von den durchführenden Fachkräften akzeptiert wird.
