Heat Strain In Road Construction Workers During The Summer, An Observational Study, Serena Garcia

International Journal of Exercise Science: Conference Proceedings

Road construction workers perform physically demanding, typically including building frames, laying concrete and asphalt, and operating heavy machinery. These activities result in high metabolic demands, leading to significant internal heat production. When combined with environmental heat stress during warmer periods of the year, road construction workers may experience substantial heat strain, making them susceptible to heat-related illnesses and ultimately heat-related deaths. In fact, construction workers are 13 times more likely to die from heat related illness compared to other occupations. Despite these statistics, no studies have assessed heat strain in road construction workers during the summer. PURPOSE: To quantify …

Effects Of Biodensity Training On Bone Adaptations In Young Women: A Pilot Study, Carolina M. Garcia, Auguste Torres, Braulio Cazarez, Rosalinda Escobar-Prado, Maurice Cruz, Zhaojing Chen

International Journal of Exercise Science: Conference Proceedings

Osteopenia and osteoporosis are a major public health issue in the United States, and current research suggests that moderate to high intensity resistance training is the most effective type of exercise for maintaining bone mineral density (BMD). Sclerostin is a protein secreted by osteocytes which potently inhibits bone formation by binding to the LRP4 in Wnt/β-catenin signaling. BioDensity is a novel resistance training machine that consists of four exercises performed for five seconds each, which applies mechanical loading to the bone and provides a quicker alternative to traditional resistance training. PURPOSE: To examine the effects of 12 weeks of …
