Injury in youth physical activity has become a major concern with the rising rate of participation. Lumbopelvic-hip complex (LPHC) stability, also known as core stability, has been found to contribute to proper force dissipation and ultimately more effective mechanics. Therefore, the purpose of this study was to examine the effects of a LPHC neuromuscular strengthening program on at-risk youth using the Tuck Jump Assessment. Forty-five youth grades 6, 7, and 8 participated in the Tuck Jump Assessment. Then those participants who scores were indicative of 'at risk' were enrolled in a four-week LPHC intervention program. Those participants whose sores did …

Population cycles in forest Lepidoptera often result from recurring density-dependent epizootics of entomopathogens. While these systems are typically dominated by a single pathogen species, insects are often infected by multiple pathogens, yet little is known how pathogens interact to affect host dynamics. The apparent invasion of northeastern North America by the fungal entomopathogen Entomophaga maimaiga some time prior to 1989 provides a unique opportunity to evaluate such interactions. Prior to the arrival of E. maimaga, the oscillatory dynamics of host gypsy moth, Lymantria dispar, populations were apparently driven by epizootics of a nucleopolyhedrovirus. Subsequent to its emergence, E. …
