Exercising at Work

Peak Inspiratory Flows of Adults Exercising at Light, Moderate and Heavy Work Loads

he purpose of this study was to acquire, process, and analyze ventilation and peak inspiratory airflows during exercise to obtain a representative sample set of ventilation data of the general working population. A total of 13 volunteers exercised on a treadmill at three relative work rates of 40%, 60%, and 80% of their maximal aerobic capacity. Ventilation measurements and peak inspiratory air...

Exercising for life? Energy metabolism, body composition, and longevity in mice exercising at different intensities.

Studies that have found a positive influence of moderate, nonexhaustive exercise on life expectancy contradict the rate-of-living theory, which predicts that high energy expenditure in exercising animals should shorten life. We investigated effects of exercise on energy metabolism and life span in male mice from lines that had been selectively bred for high voluntary wheel-running activity and ...

Policies to Optimize Work Performance and Thermal Safety in Exercising Humans

Emergency workers engaged in strenuous work in hot environments risk overheating and mission failure. We describe a real-time application that would reduce these risks in terms of a real-time thermal-work strain index (SI) estimator; and a Markov Decision Process (MDP) to compute optimal work rate policies. We examined the thermo-physiological responses of 14 experienced U.S. Army Ranger studen...

Fixed-term work and violence at work.

OBJECTIVES This study investigated the effect of a fixed-term job contract on encounters of violence at work. We assumed that fixed-term employees encountered more violence or threats of violence at their work than permanent employees. METHODS This study is based on 3 large statistical data sets: (a) the Work and Health surveys carried out by the Finnish Institute of Occupational Health in 19...
