The curriculum may superimpose a content-specific context that mediates motivation (Bong, 2001). This study examined content specificity of the expectancy-value motivation in elementary school physical education. Students' expectancy beliefs and perceived task values from a cardiorespiratory fitness unit, a muscular fitness unit, and a traditional skill/game unit were analyzed using constant co...

Firefighting is dangerous work. Each year, approximately 80,000 firefighters are injured and about 100 firefighters lose their lives in the line of duty. Firefighters face multiple dangers in the course of their work; they encounter toxic fumes, dangerous products of combustion, high radiant heat loads, and a chaotic work environment. Despite the myriad dangers, the leading cause of line-of-dut...

This systematic review and meta-analysis aimed to examine the effects of home-based exercise programmes on measures physical-fitness in healthy older adults. Seventeen randomized-controlled trials were included with a total 1,477 participants. Results indicated small training muscle strength (between-study standardised-mean-difference [SMD] = 0.30), power (SMD 0.43), muscular endurance 0.28), b...

When students analyze and present original data they have collected, and hence have a cultivated sense of curiosity about the data, student learning is enhanced. It is often difficult to provide students an opportunity to practice their skills, use their knowledge, and gain research experiences during a typical course laboratory. This article describes a model of an out-of-classroom experience ...

BACKGROUND Adiposity is correlated with metabolic complications, such as insulin resistance, glucose intolerance, hypertension etc. that finally can lead to coronary heart disease (CHD). Physical activity plays an important role in prevention of these diseases. We aimed to study body fat and plasma lipids and lipoproteins in different levels of physical fitness; also to examine any relationship...
