Computer modelling of heat strain responses of exercising personnel in tropical climate.

Physiologically based thermoregulatory models are useful for deriving predictions of heat strain for pragmatic applications such as planning of continuous exercise/work-rest protocols. The SCENARIO model is an example of a thermoregulatory model that predicts heat strain including body core temperature (Tc) from individual characteristics, physical activity, clothing properties and environmental conditions. This paper presents work to optimize and enhance the SCENARIO model for prediction of Tc during high intensity load carriage tasks under predominantly tropical climate conditions.

Anterior cruciate ligament failure and cartilage damage during knee joint compression: a preliminary study based on the porcine model.

Background: Anterior cruciate ligament (ACL) injury incurred from high-impact activities leads to an increased risk of osteoarthritis.

Hypothesis: Impact forces that cause ACL failure can also inflict cartilage damage, whereby its extent and distribution may be influenced by the ligament failure mechanism.

Study Design: Descriptive laboratory study.
