Physical Activity in the Workplace: Does Just Working Meet Activity Recommendations?

: The physical activity (PA) health paradox hypothesizes that occupational physical activity (OPA) and leisure time PA have differential cardiovascular health effects due to increased cardiovascular load without adequate recovery; however, research describing worker PA lacks high-quality objective OPA measurement. This study aimed to objectively describe PA profiles of men reporting high OPA and make comparisons to aerobic PA and OPA recommendations. : Male food service, material moving, health care, or maintenance workers wore activity (ActiGraph and activPAL) and heart rate monitors for 7 days.

Cardiovascular responses to physical activity during work and leisure.

Objectives: Recent evidence suggests that occupational physical activity (OPA) is associated with adverse cardiovascular health, whereas leisure time physical activity is protective. This study explored explanatory physiological mechanisms.

Methods: Nineteen males (68% white, age=46.

Probability of hyperthermia in a hot environment while wearing a liquid cooling garment underneath firefighters' protective clothing.

Firefighters' protective clothing (FPC) can limit human thermoregulation due to limited water vapor permeability and insulation. This study investigated the effect of cooling on the physiological responses and probability of hyperthermia in subjects wearing FPC during exercise in a hot environment. Twelve males participated in this study.

Occupational physical activity and cardiovascular disease in the United States.

Background: Emerging evidence, predominately from European and Asian countries, describes opposing effects of occupational physical activity (OPA) and leisure-time physical activity (LTPA) on cardiovascular health. This analysis examined cardiovascular disease (CVD) prevalence associated with OPA and LTPA.

Methods: This cross-sectional analysis of 2015 National Health Interview Survey data (n=16 974) employed logistic regression to estimate odds (OR) of self-reported CVD (coronary heart disease, heart attack, stroke or angina) with self-reported total occupational activity (TOA), occupational exertion (OE), occupational standing and walking (OSW) and LTPA.

Effect of continuous cooling on inhibition and attention while wearing firefighter's PPE in a hot environment.
