1. Lanza, Kevin. Red hot American summer: Extreme heat and physical activity of adults.

Degree: PhD, City and Regional Planning, 2018, Georgia Tech

This dissertation investigates the relationship between extreme summer heat and outdoor, indoor, and total (i.e., outdoor + indoor) physical activity levels of US adults. With the lack of physical activity across the US, public health practitioners and city planners are making concerted efforts to promote physical activity through formal interventions and the design of spaces, respectively. To inform physical activity interventions, researchers examine which factors associate with physical activity, one of which is temperature. The majority of studies exhibit a significant positive association between temperature and physical activity, yet no studies examine exceptionally hot summer days, which disproportionately impact cities and are set to become more prevalent in the future. This dissertation tests three novel questions: 1) how do hot days associate with outdoor, indoor, and total physical activity; 2) how do hot days influence the effect of built environment factors on outdoor physical activity; and 3) how do heat waves – consecutive hot days – associate with outdoor, indoor, and total physical activity? This work made use of self-reported physical activity and demographic data collected during summer 2016 for a National Science Foundation project (NSF award number: 1520803). The study sample included a spatial and demographic mix of ~50 adults per study city (i.e., Atlanta, Detroit, and Phoenix). Heat was measured as both hot days and heat waves (i.e., two or more consecutive hot days), utilizing air temperature and relative humidity data collected at each city’s major airport. The examined built environment factors (i.e., density, safety, trees, hilliness, connectivity, access to parks, and access to shops + services) were primarily collected from government sources and calculated within an 800m Euclidean distance of each study participant’s home address. Separate two-level growth curve models were run for each research question, version of the dependent variable (i.e., Any Activity and Recommended Activity), and location of physical activity (i.e., outdoor, indoor, and total). Multilevel modeling predicted that 1) hot days do not exhibit a significant association with indoor, outdoor, or total physical activity; 2) hot days do not significantly influence the effect of built environment factors on outdoor physical activity; and 3) heat waves do not exhibit a significant association with outdoor, indoor, or total physical activity. These findings refute the study hypotheses that extreme summer heat would decrease outdoor and total physical activity, while shifting physical activity to indoor, thermally comfortable environments. With high temperatures potentially not serving as a barrier to physical activity, cities should allocate resources to reducing the risk of exertional heat illness, an adverse health event expected to become more frequent with physical activity promotion and climate change.

2. Heynes, Andre. The vulnerability of adolescents participating in rugby and football in Dubai, UAE, to exertional heat illness.

Degree: MScPhysio, Health, 2018, Stellenbosch University

ENGLISH SUMMARY : Background: Regular appropriate physical activity for children and adolescents are needed to improve and maintain health. There are several risk factors for developing exertional heat illness (EHI), which negatively affect the thermoregulatory ability of the body, resulting in increased core body temperature. Exercising in high environmental temperatures and humidity increase the risk for EHI. Dubai, UAE, experience these environmental conditions. EHI presents as symptoms ranging from exercise associated muscle cramps, heat syncope and exercise related collapse, heat exhaustion, and exertional heat stroke. In the USA, exertional heat stroke is the leading cause of death in young athletes. Objective: To determine the vulnerability of adolescent union rugby and football participants in terms of risk factors present for EHI, self-reported EHI symptoms and the hydration practices of the participants for the duration of the study. Methods: A cross-sectional, descriptive design was used to address the research questions. The study was conducted at clubs offering union rugby or football in the Middle Eastern city of Dubai, UAE. Population sampling was applied, which included adolescents, aged between 10 -19 years old. The study occurred during a single training session at the start of the 2015/2016 season, during the month of October 2015. A questionnaire was used to elicit responses from the participants to measure self-reported risk factors, symptoms of EHI and hydration practices. Results: A response rate of 22.4% (n= 111) was obtained, 49 union rugby and 62 football participants were recruited from a total of 500 players that initially attended the information session. The main findings of the study include: 19 % (n=21) of participants self-reported EHI risk factors; 14.4% (n= 16) of participants’ self-reported exercises-associated muscles cramps, which was the only EHI symptom category, and 10.8% (n= 12) of participants did not report any EHI symptom. Fluid was consumed by 94.5% (n= 105) before training, 100% (n= 111) during training, and 100% after training. Water was the most abundant fluid consumed before (86%, n= 91), during (94.5%, n=105) or after (55%, n= 61) training. Many participants (77.5%, n= 86) indicated that they are knowledgeable if they consumed too much fluid. Beside fluid provided by the two football clubs, no other side-line support measures were noted. Poorer general physical fitness was associated with more EHI symptoms (rho = -0.211, p = .026). An additional significant association was found between the number of EHI risk factors and the fluid intake volume after practice, with higher intake being associated with more symptoms (rho = 0.197, p = .043). In those participants who reported generally better physical fitness (rho = -0.206, p = .030), significantly fewer EHI symptoms were noted. For those participants who reported consuming more fluids before practice (rho = 0.313, p = .001), and consuming fluids a longer time prior to practice (rho = 0.253, p = .009), the number of… Advisors/Committee Members: Louw, Quinette, Ernstzen, Dawn, Potgieter, Sunita, Stellenbosch University.
