Motivation Matters: Understanding The Antidepressant Mechanism Of Physical Activity Among Young Adults, Jessica E. H. Ryan, Travis R. Menuz, Megan E. Ames
International Journal of Exercise Science
International Journal of Exercise Science 17(5): 861-873, 2024. A negative association between physical activity and depressive symptoms is consistently reported within scientific literature and physical self-concept has been suggested to mediate this pathway. However, for whom these associations are strongest remains poorly understood, and little is known about how other psychosocial factors might be implicated. Consequently, we examined how various exercise motivations, specifically appearance, physical health, and mental health, might moderate the indirect effect of physical activity on depressive symptoms through physical self-concept. Canadian young adults (N = 496, Mage = 20.36, SD = 1.87) completed an online questionnaire. …

International Journal of Exercise Science
International Journal of Exercise Science 17(4): 768-778, 2024. The objectives of this study were to report weight-normalized, sex- and sport-stratified normative values for hamstrings and quadriceps isometric strength in collegiate soccer and basketball players using a low-cost hand-held dynamometer and assess the prevalence of “substantial” hamstrings-quadriceps (H/Q) ratio strength imbalance (<0.6) among players. Ninety-four healthy collegiate male and female soccer and basketball players (age range: 18–24 years) were examined for baseline isometric hamstrings and quadriceps strength using a handheld isometric dynamometer with standardized and valid protocols. For soccer, the mean (95%CI) weight-normalized peak isometric strength values (considering dominant limbs) were 3.29 (2.90 to 3.64) N/kg (hamstrings) and 5.48 (4.96 to 6.00) N/kg (quadriceps) in male players and 2.62 (2.39 to 2.85) N/kg (hamstrings) and 4.55 (4.14 to 4.96) N/kg (quadriceps) in female players. For basketball, the mean (95% CI) peak strength values were 2.97 (2.72 to 3.21) N/kg (hamstrings) and 4.89 (4.44 to 5.33) N/kg (quadriceps) in male players and 2.48 (2.15 to 2.80) N/kg (hamstrings) and 4.21 (3.54 to 4.87) N/kg (quadriceps) in female players. The prevalence of substantial H/Q strength imbalance was 37% (95%CI: 24% to 52%) in soccer and 44% (95%CI: 29% to 60%) in basketball players. This study is first to provide normative values for peak isometric hamstrings and quadriceps strength using a low-cost hand-held dynamometer. The normative database from this study is valuable to coaches, sports medicine professionals, exercise scientists and other stakeholders to inform injury prevention, rehabilitation progression, return to play decisions and performance goals in collegiate soccer and basketball players.

Patterns And Potential Mechanisms Of Phenotypic Changes In Urban Small Mammals, Leslie Lopez
Master's Theses
Urbanization is an example of human induced rapid environmental change that can have wide-reaching ecological effects, including habitat destruction, fragmentation, and alteration of local climates. Effects of urbanization have been shown to impact wildlife, as disturbances resulting from urbanization can create novel environments and selective pressures that could lead to changes in morphology, physiology, or both. Small mammals such as rodents are an ecologically important set of wildlife species because they are a key prey item for several predators, hold strong influence over plants as a primary consumer, and some species carry and transmit major human and animal diseases.
