Objectives To examine the effects of sleep restriction on firefighters' physical task performance during simulated wildfire suppression. Methods Thirty-five firefighters were matched and randomly allocated to either a control condition (8-hour opportunity, n = 18) or restricted (4-hour 17). Performance work tasks was evaluated across three days. In addition, heart rate, core temperature, worker activity measured continuously. Rate perceived exertion effort sensation periods. Results There no...
This study examined the effect of body armor during repeated, intermittent high-intensity simulated military work. Twelve males performed 11 repetitions a style circuit, wearing no on one occasion and full (∼17 kg) another. Performance was measured by time to complete individual work tasks plus overall circuit completion. Heart rate, intestinal temperature, rating perceived exertion were recorded after each circuit. Participants' completion 7.3 ± 1.0 seconds slower (p < 0.01) when armor....
Objectives This study investigated the effect restricted sleep has on wildland firefighters' acute cytokine levels during 3 days and 2 nights of simulated physical wildfire suppression work. Methods Firefighters completed multiple firefighting work separated by either an 8-h (Control condition; n = 18) or 4-h (Sleep restriction 17) opportunity each night. Blood samples were collected 4 times a day (i.e., 06:15, 11:30, 18:15, 21:30) from which plasma (IL-6, IL-8, IL-1β, TNF-α, IL-4, IL-10)...
Background: The severity of wildland fires is increasing due to continually hotter and drier summers. Firefighters are required make life altering decisions on the fireground, which requires analytical thinking, problem solving, situational awareness. This study aimed determine effects very hot (45°C; HOT) conditions cognitive function following periods simulated wildfire suppression work when compared a temperate environment (18°C; CON). Methods: Ten male volunteer firefighters...
This study investigated the association between synthetic ovarian hormone use [i.e., oral contraceptive (OC) pill] and basal C-reactive protein (CRP), peripheral blood immune cell subsets, circulating pro- anti-inflammatory cytokine concentrations in elite female athletes. Elite athletes (n = 53) selected Rio Summer Olympic squads participated this study; 25 were taking an OC (AthletesOC) 28 naturally hormonally cycling (AthletesNC). Venous samples collected at rest for determination of sex...
Over the past ten years there has been a dramatic rise in female sport participation and accompanying professional national leagues across multiple sports, yet research not followed suit. Although are known variations between male physiology, training protocols predominantly underpinned by undertaken athletes. The hormonal variability experienced women menstrual cycle, as well cycle women, may contribute to complexity of conducting rigorous physiological studies, leading paucity robust...
This study assessed the accumulated effect of ambient heat on performance of, and physiological perceptual responses to, intermittent, simulated wildfire fighting tasks over three consecutive days. Firefighters (n = 36) were matched allocated to either CON (19°C) or HOT (33°C) condition. They performed days self-paced firefighting work, interspersed with testing. Task repetitions counted (and converted distance area) determine work performance. Participants asked rate their perceived...
To assess the impact of very hot (45°C) conditions on performance of, and physiological responses to, a simulated firefighting manual-handling task compared to same work in temperate environment (18°C).
This study investigated the injuries sustained by an Australian specialist police division. Injury records spanning four-years were analyzed. The role being performed when injury occurred, cause, body part injured, and injury-related costs quantified. percentage of personnel injured multiple times was documented. One hundred thirty eight reported injuries, 58 these on occasions. resulted in 229 76 claims raised. Half occurred during operational policing tasks, however training activities...
This study was designed to examine the effects of ambient heat on firefighters’ physical task performance, and physiological perceptual responses when sleep restricted during simulated wildfire conditions. Thirty firefighters were randomly allocated (n = 17, SR; 19 °C, 4-h opportunity) or hot 13, HOT + 33 condition. Firefighters performed two days simulated, intermittent, self-paced work circuits comprising six firefighting tasks. Heart rate, core temperature measured continuously. After...
We sought to determine whether oral contraception alters the gender-related differences observed in exercise pressor reflex during isometric handgrip exercise. Fifteen men, fifteen normally menstruating women (WomenNM), and taking monophasic contraceptives (WomenOC) completed two trials of a 3-min protocol performed at 30% their maximal voluntary contraction: (1) where arterial occlusion was applied previously exercising arm recovery period (Occlusion trial); (2) no (Control trial). Handgrip...
Workers in physically demanding occupations (PDOs) are frequently subjected to physical selection tests. To avoid legal ramifications, workplaces must be able show that any personnel procedures reflect the inherent requirements of job. A job task analysis (JTA) is fundamental determining work tasks required for employees. date, there no published instructions guiding PDO researchers on how conduct analyses. Job research non-PDOs offers some insight into expected reliability and validity data...
Despite cross-cultural differences in knowledge and attitudes toward menstruation, most studies on menstruation women’s sport have been conducted high-income countries, such as Europe, none Africa. The aim of this study was to explore the knowledge, attitudes, behaviors African elite women football players, their support personnel menstrual cycle menstruation. An anonymous questionnaire distributed all participants ( n = 564) at two tournaments. Ultimately, 238 44 coaches, 18 health...
