Salsa Dance and Perceived Mental Health Benefits: A Servant Leadership Theory-Driven Study

The purpose of the current study was to assess servant leadership dimensions, perceived mental health benefits, and correlations between the two following an eight-week servant leadership theory-driven salsa dance programme taught to novice learners at a West Midlands, UK university. Upon completion of the salsa dance programme (frequency – once per week, intensity – moderate-to-vigorous physical activity, time – 90 minutes, type – group-based Cuban style salsa dance), a paper questionnaire was administered to the participants to complete in person. The questionnaire contained 18 items related to servant leadership dimensions (authenticity, empowerment, humility, standing back, and stewardship) in terms of the teaching and learning of salsa dance and four items related to perceived mental health benefits (mood enhancement, self-confidence, skill mastery, and social well-being). Authenticity and stewardship were rated higher in females when compared to males. Differences were found between perceived mental health benefits in both females and males with mood enhancement rated highest in both genders. This is the first study we are aware of to have applied principles of servant leadership in the teaching of salsa dance as a leisure-time physical activity. Servant leadership may have facilitated the high perceived mental health benefits observed

The health-enhancing efficacy of Zumba® fitness : an 8-week randomised controlled study

The purpose of this study was to gain a holistic understanding of the efficacy of Zumba® fitness in a community-recruited cohort of overweight and physically inactive women by evaluating (i) its physiological effects on cardiovascular risk factors and inflammatory biomarkers and (ii) its mental health-enhancing effects on factors of health-related quality of life (HRQoL). Participants were randomly assigned to either engagement in one to two 1 h classes of Zumba® fitness weekly (intervention group; n = 10) or maintenance of habitual activity (control group; n = 10). Laboratory assessments were conducted pre- (week 0) and post-intervention (week 8) with anthropometric, physiological, inflammatory and HRQoL data collected. In the intervention group, maximal oxygen uptake significantly increased (P < 0.05; partial η(2) = 0.56) by 3.1 mL · kg(-1) · min(-1), per cent body fat significantly decreased (P < 0.05; partial η(2) = 0.42) by -1.2%, and interleukin-6 and white blood cell (WBC) count both significantly decreased (P < 0.01) by -0.4 pg · mL(-1) (partial η(2) = 0.96) and -2.1 × 10(9) cells · L(-1) (partial η(2) = 0.87), respectively. Large magnitude enhancements were observed in the HRQoL factors of physical functioning, general health, energy/fatigue and emotional well-being. When interpreted in a community-based physical activity and psychosocial health promotion context, our data suggest that Zumba® fitness is indeed an efficacious health-enhancing activity for adults

Partial growth hormone insensitivity and dysregulatory immune disease associated with de novo germline activating STAT3 mutations

Germinal heterozygous activating STAT3 mutations represent a novel monogenic defect associated with multi-organ autoimmune disease and, in some cases, severe growth retardation. By using whole-exome sequencing, we identified two novel STAT3 mutations, p.E616del and p.C426R, in two unrelated pediatric patients with IGF-I deficiency and immune dysregulation. The functional analyses showed that both variants were gain-of-function (GOF), although they were not constitutively phosphorylated. They presented differences in their dephosphorylation kinetics and transcriptional activities under interleukin-6 stimulation. Both variants increased their transcriptional activities in response to growth hormone (GH) treatment. Nonetheless, STAT5b transcriptional activity was diminished in the presence of STAT3 GOF variants, suggesting a disruptive role of STAT3 GOF variants in the GH signaling pathway. This study highlights the broad clinical spectrum of patients presenting activating STAT3 mutations and explores the underlying molecular pathway responsible for this condition, suggesting that different mutations may drive increased activity by slightly different mechanisms.Fil: Gutiérrez, Mariana Lilián.

The reference site collaborative network of the european innovation partnership on active and healthy ageing

Seventy four Reference Sites of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) have been recognised by the European Commission in 2016 for their commitment to excellence in investing and scaling up innovative solutions for active and healthy ageing. The Reference Site Collaborative Network (RSCN) brings together the EIP on AHA Reference Sites awarded by the European Commission, and Candidate Reference Sites into a single forum. The overarching goals are to promote cooperation, share and transfer good practice and solutions in the development and scaling up of health and care strategies, policies and service delivery models, while at the same time supporting the action groups in their work. The RSCN aspires to be recognized by the EU Commission as the principal forum and authority representing all EIP on AHA Reference Sites. The RSCN will contribute to achieve the goals of the EIP on AHA by improving health and care outcomes for citizens across Europe, and the development of sustainable economic growth and the creation of jobs

Efficacy of Latin dance as a health-enhancing leisure activity for adults

Despite acceptance that physical activity serves as a protective agent against the burden of non-communicable disease, half of all adults in the developed world remain insufficiently physically active. The promotion of physical activity is therefore of paramount importance to public health researchers and practitioners. Dance, as a leisure or social activity, can play a role in the engagement of adults in physically active pursuits that are not necessarily thought of as traditional exercise per se. This is especially important for those individuals not currently meeting physical activity guidelines and is fully congruent with the current public health message that "some activity is better than none". A holistic exploration of Latin dance was undertaken in this thesis in the context of physical activity and psychosocial health promotion in non-clinical adults. The research encompassed a quantitative assessment of physiological and psychological measures related to dance. Over a 3 yr period, eighty-four women and men were enrolled in a series of four interrelated Latin dance (salsa) and Latin-themed aerobic dance (Zumba fitness) studies. Research grade motion sensing and heart rate monitors were used to evaluate the physiological responses to dance, and a novel activity-specific value calibration method was developed to process the data. The monitors, which are small and unobtrusive to wear, were then utilised for collection of data during performance of dance in naturalistic settings. Psychological measures associated with dance participation were captured using previously validated questionnaires. Results indicate that Latin dance elicits physiological responses representative of moderate to vigorous physical activity when performed primarily for leisure purposes. Modest improvements were observed post-dance in measures of cardiorespiratory fitness, body composition, and inflammatory biomarkers in relation to cardiovascular health. Moreover, participation fostered interest, enjoyment, and a positive psychological outlook, and enhanced well-being, mood, and health-related quality of life with large magnitude effects. The findings of this thesis may be relevant for researchers and practitioners interested in the efficacy of dance as an expressive and creative medium for the promotion of physical and mental health

Combined triaxial accelerometry and heart rate telemetry for the physiological characterization of Latin dance in non-professional adults.

The purpose of this study was to value calibrate, cross-validate, and determine the reliability of a combined triaxial accelerometry and heart rate telemetry technique for characterizing the physiological and physical activity parameters of Latin dance. Twenty-two non-professional adult Latin dancers attended two laboratory-based dance trials each. After familiarization and a standardized warm-up, a multi-stage (3 x 5-minute) incremental (based on song tempo) Afro-Cuban salsa choreography was performed while following a video displayed on a projection screen. Data were collected with a portable indirect calorimeter, a heart rate telemeter, and wrist-, hip-, and ankle-mounted ActiGraph GT3X+ accelerometers. Prediction equations for energy expenditure and step count were value calibrated using forced entry multiple regression and cross-validated using a delete-one jackknife approach with additional Bland-Altman analysis. The average dance intensity reached 6.09 ± 0.96 kcal/kg/h and demanded 45.9 ± 11.3% of the heart rate reserve. Predictive ability of the derived models was satisfactory, where R(2) = 0.80; SEE = 0.44 kcal/kg/h and R(2) = 0.74; SEE = 3 step/min for energy expenditure and step count, respectively. Dependent t-tests indicated no differences between predicted and measured values for both energy expenditure (t65 = -0.25, p = 0.80) and step count (t65 = -0.89, p = 0.38). The 95% limits of agreement for energy expenditure and step count were -0.98 to 0.95 kcal/kg/h and -7 to 7 step/min, respectively. Latin dance to salsa music elicits physiological responses representative of moderate to vigorous physical activity, and a wrist-worn accelerometer with simultaneous heart rate measurement constitutes a valid and reliable technique for the prediction of energy expenditure and step count during Latin dance
