Ten men (non-firefighters) completed a 110 min walking/recovery protocol (three 20-min exercise bouts, with recovery periods of 10, 20, and 20 min following successive bouts) in a thermoneutral laboratory while wearing firefighting personal protective equipment over one of four base layers: cotton, modacrylic, wool, and phase change material. There were no significant differences in changes in ...

This manuscript describes a "dry laboratory" using the "virtual rat" to help students understand the hormonal regulation of gastrointestinal function. The laboratory was modeled after a recent exercise that used the virtual rat to teach basic endocrine physiology. The virtual rat concept avoids the many obstacles associated with animal experimentation (for example, lack of adequate animal facil...

Limitation of exercise capacity is a hallmark of chronic congestive heart failure (HF), varying directly with the severity of the disease. Muscular fatigue and dyspnea on exertion are the most common symptoms of exercise intolerance; however, their origin is still not fully explained. Heart failure is a multifaceted clinical syndrome characterized by the inability of the heart to generate cardi...

In recent years increasing emphasis has been placed on the benefits of exercise to normal healthy adults as well as to those recovering from heart attacks and other illnesses. As an aid to exercise training many portable heart-rate monitors have been placed on the market but little appears to have been done to assess the performance of these machines. The authors have examined the performance o...

The current paper describes research that is aimed to elucidate our understanding of technology factors that may help users of home exercise equipment to stay motivated for doing regular work-outs. In particular, we investigated the effects of immersion and coaching by a virtual agent on intrinsic motivation and the sense of presence of participants cycling on a stationary home exercise bike. A...

We study options on short-term leases for capital-intensive equipment performing specific functions and services, such as leases for semi-submersible drilling rigs, marine seismic services, corporate real estate leasing, retail space leasing, and apartment leasing. We quantify the effect of an important factor in pricing options on these services: idle time between consecutive lease contracts. ...

[Purpose] This study aimed to examine that therapeutic efficacy of an unstable surface on balance and gait ability in normal individuals. [Subjects and Methods] Forty subjects participated in the experiment and were randomly assigned to an experimental group of 20 subjects and a control group of 20 subjects. The experimental group performed balance exercise on an Aero-Step device (Aero-Step XL,...

A barrier to using head mounted display (HMD) virtual reality (VR) in education is access hardware for large classes. This paper compares students’ learning when engaging with an HMD VR simulation as the operator and observer, evaluate whether benefits of can be achieved without requiring all students operate equipment. Postgraduate engineering (N = 117) completed a safety hazard identification...

The current paper describes research that is aimed at elucidating our understanding of media technology factors that may help users of exercise equipment to stay motivated for doing regular workouts. In particular, we investigated the effects of immersion and coaching by a virtual agent on intrinsic motivation and the sense of presence of participants cycling on a stationary home exercise bike....
