Physical Activity: A Tool for Improving Health (Part 2—Mental Health Benefits)

By promoting physical activities and incorporating them into their community-based programs, Extension professionals are improving the health of individuals, particularly those with limited resources. This article is the second in a three-part series describing the benefits of physical activity for human health: (1) biological health benefits of physical activity, (2) mental health benefits of physical activity, and (3) recommended amounts of physical activity for optimal health. Each part of the series is designed to help Extension professionals effectively integrate physical activity into community programs and motivate individuals to maintain an interest in being physically active during and after a program

The USDA\u27s Healthy Eating on a Budget Program: Making Better Eating Decisions on a Budget

The U.S. Department of Agriculture has launched a new interactive online program titled Healthy Eating on a Budget. It is an addition to the popular ChooseMyPlate.gov programs, such as the SuperTracker program. The Healthy Eating on a Budget program helps consumers plan, purchase, and prepare healthful meals. This article discusses materials and resources that are available as part of the Healthy Eating on a Budget program and provides suggestions for ways in which Extension professionals who teach consumers how to improve their nutrition and make nutrition affordable can use the program

Theoretical elastic tensile behavior of muscle fiber bundles in traumatic loading events

BackgroundThe mechanical characterization of skeletal muscle under high-rate loading regimes is important for predicting traumatic injuries due to traffic accidents and contact sports. However, it is difficult to perform dynamic mechanical tests at rates relevant to such rapid loading events. MethodsIn the present study, a series of stress relaxation tests were conducted on rabbit hind-limb muscle fiber bundles using a custom tensile tester. Using relatively moderate loading conditions compared to those typically associated with traumatic injuries, the passive stress-decaying mechanical properties of muscle fiber bundles were characterized. In addition, stress relaxation responses to various ramp-hold stretches were theoretically predicted by a custom-built code. FindingsThe results showed that the muscle fiber bundles exhibit greater stress relaxation at higher loading rates and greater stretch magnitudes. Based on these results, the data points representing the “elastic” stress–strain tensile behavior typical of traumatic injury were extrapolated using curve fitting. The theoretical model revealed rate-dependent characteristics of the muscle fiber bundles under traumatic loading conditions, which would result in tensile strengths of 300–500 kPa at the maximum engineering strain of 54%. This strength is on the order of magnitude as the maximum isometric stress of an active muscle contraction. InterpretationThe proposed numerical model is expected to serve as a powerful research tool to investigate injury mechanisms of the skeletal muscle. Moreover, the elastic response that was theoretically predicted here will be useful in the development of effective countermeasures to prevent traumatic injuries due to rapid loading events

Financial sector shocks, external finance premium and business cycle

This paper extends Nolan and Thoenissen (2009), hence NT, model with an explicit financial intermediary that transfer funds from households to entrepreneurs subject to a well defined loan production function. The loan productivity shock is treated as the supply side financial disturbance. Together with NT’s net worth shock that resembles the credit demand perturbation, both of the two-sided shocks are robustly extracted by combining the model with US quarterly data. The two shocks are found to be tightly linked with the post-war recessions. Each recession happens when both of the two shocks become contractionary. A few potential economic downturns seem to have been avoided because of the expansion of credit which offset the simultaneous contraction of entrepreneurial net wealth. This new introduced shock has significant explanatory power for the variance of EFP and the model simulated EFP holds high correlation with various spreads as proxies for empirical EFP
