Section 1

Question Answer
Burke 2006: overviewmeta-analysis on group vs home based interventions
Burke 2006: discussion improvements seen in home based with contact and group, but not in home with no contact. no difference in adherence between home with contact and collective - self report? or similar environments. Exercising in a true group is superior to exercising in a collective for adherence.
Burke 2006: limitationsparticipants generally 50+ years. hardly any were randomly selected, those randomised to a non-preferred context may perform or adhere more poorly. majority short term studies.

Section 2

Question Answer
Estabrooks 2012: overviewWe conducted a systematic review to identify studies that used different group dynamics strategies to promote physical activity. Seventeen studies were identified and were coded by two raters to determine the degree to which group dynamics strategies were used, the format of the programs, and any analytic procedures used to determine the causal mechanisms underlying intervention effectiveness
Estabrooks 2012: resultsThe results of the coding indicated that while there is no standard package of group dynamics strategies being applied across the literature- and regardless of the breadth of the underlying theory or the structure of the programs- the effect on physical activity is robust. However, few studies explicitly measured potential causal mechanisms and even fewer completed the necessary analysis to detect mediation.
Estabrooks 2012: summaryWe concluded that future research on developing a unified theory for group dynamics with appropriate measurement tools is necessary to further enhance the effects of group dynamics on physical activity promotion.

Section 3

Question Answer
Forrest 2015: overviewteam building intervention online. evaluate efficacy, phase 1 = questionnaires on cohesion and group tasks, pre and post fitness tests. Phase 2 = adherers, drop outs and exercise leaders in focus group interviews.
Forrest 2015: resultsResults revealed that post-intervention, cohesion increased along with group task satisfaction and measures of physical fitness, Themes emerged revealing reasons for adherence, such as cohesion, as well as reasons for dropout, such as perceived lack of time
Forrest 2015: summaryCollectively, the findings support the efficacy of an online TB exercise intervention to foster cohesion, increase group task satisfaction and improve physical fitness
