Analyzing Sex Differences In Human Performance Through 3d Isotonic Resistance, Jacob M. Cunha

University of the Pacific Theses and Dissertations

Appraisal of scientific literature and understanding continues to grow in the domain of human performance. The effects of sex on concentric resistance training and power output are not well understood. Recent advancements in technology permit more precise measurements of force output and the kinematic changes elicited by training stress. A unique device in capturing kinematic performance output is Proteus Motion. The machine produces an external magnetic load through a protruding apparatus connected to a gyrosphere, which in turn captures concentric movement through all three planes of movement (sagittal, coronal, transversal). The aim of this study is to investigate power output …

Is Early Sport Specialization Harming Our Children?, Kendra Dunsford Dpt, Scs, Stc, Preeti Oza Pt, Phd

Pacific Journal of Health

Sports and physical activity in children are healthy and have numerous positive mental and physical health benefits. Recently, there has been a shift away from deliberate play and focusing on specializing in a single sport from a young age. Participating in rigorous training and competition schedules 8 months out of the year for prepubescent athletes has garnered attention from the medical community. It is assumed that this type of early specialization has the potential to cause negative effects, especially in terms of overuse injuries, nutritional deficiencies, poor sleep hygiene, and mental health concerns. While there appears to be a consensus …
