Research Paper Title Effect of Environmental Temperature and Humidity on Permethrin Biomarkers of Exposure in U.S. Soldiers Wearing Permethrin-Treated Uniforms. Background Environmental factors, including high temperature and humidity, can influence dermal absorption of chemicals. Soldiers can be dermally exposed to permethrin while wearing permethrin-treated uniforms. This study aimed at examining the effects of high temperature… Read More
Discerning the Interaction Between Ambient Temperature, Hypoxia, & Load Carriage on Respiratory Muscle Fatigue
Research Paper Title Interaction Between Ambient Temperature, Hypoxia, and Load Carriage on Respiratory Muscle Fatigue. Background While respiratory muscle fatigue is present following load carriage activity at sea level, the effect of environmental conditions on respiratory strength while undertaking load carriage is unknown. Methods The effect of thoracic load carriage during walks (5.5 km) in… Read More
What is the RAMP Method (as used in Exercise & Fitness)?
Warming-up (or movement preparation) before a training session is crucial in aiding participants to get the best results from their session. A RAMP warm-up, developed by Dr. Ian Jeffreys, can be very useful (for both trainers and participants) in making sure that the body is well prepared and ready for the coming exercise. RAMP stands for:… Read More
Military Working Dogs & Core Temperature Response
Research Paper Title Core temperature responses of military working dogs during training activities and exercise walks. Background Heat strain is common in military working dogs (MWDs), but can be mitigated by limiting duration of activity to avoid overheating and allowing sufficient time for recovery. To determine work/rest times for MWDs, temperature responses during training must… Read More
Heat Acclimatisation: What is the Value of Short-term, Low-volume Training in the Operational Context?
Research Paper Title Short-Term, Low-Volume Training Improves Heat Acclimatization in an Operational Context. Background Personnel who travel to areas with a hot climate (WBGT > 27°C) may suffer from the heat (physiological strain, thermal discomfort, increased probability of heat illness), making them partially or fully inoperative. Performing physical activities during heat acclimatisation is known to… Read More
Determining the Effect of Low Ambient Relative Humidity during Load Carriage
Research Paper Title The Effect of Low Ambient Relative Humidity on Physical Performance and Perceptual Responses during Load Carriage Background The study evaluated the effect of low ambient relative humidity on physical performance and perceptual responses during load carriage in a hot environment. Methods Ten heat-unacclimatised male subjects participated in three 130-min trials, during which… Read More
Mitochondria: Hot Stuff!
“YOUR body might not get much higher than 37°C on a normal day, but it turns out that the insides of our cells can reach close to 50°C. The mitochondria in our cells burn food to produce energy. Unlike a fire, this is a controlled process involving several steps, but it still generates a lot of… Read More
