Relationships Among Maximal And Explosive Strength Production Of The Leg Extensors And Vertical Jump Peak Power Output In Female Youth Volleyball Athletes, Alexander S. Drusch, Jacob A. Mota, Kendra D. Olinghouse, Matt S. Stock, Brennan J. Thompson

International Journal of Exercise Science: Conference Proceedings

ABSTRACT

Architectural and physical performance measurements are commonly implemented to identify various physical capacities in many populations. However, previous research has suggested architectural measures, notably in the leg extensors, are ineffective predictors of vertical jumping (VJ) performance. Given the functional relevance of rapid strength development on explosive dynamic tasks, further research is warranted examining, a) the presence of associations of maximal (e.g., peak torque; PT) and, in particular, explosive (e.g., rate of torque development; RTD) strength-related characteristics with jumping performance in the leg extensors, and b) the extent to which PT and RTD either uniquely, or synergistically contribute to VJ …

Comparison Of The Ymca Cycle Sub-Maximal Vo2 Max Test To A Treadmill Vo2 Max Test, Jeremy G. Carter, Kelly A. Brooks, Joshua R. Sparks

International Journal of Exercise Science: Conference Proceedings

INTRODUCTION: An individual’s maximum capacity to extract, transport, and utilize oxygen is reflected by their VO2 max (10,22). Numerous physiological factors affect a person’s maximal oxygen consumption. A person’s VO2 max is dependent on their pulmonary, cardiovascular, and muscular systems, which depends on their ventilation-aeration efficiency, central and peripheral blood flow, and metabolism of their active muscles (13,17). The six factors that have the most influence on a person’s maximal aerobic power are heredity, state of training, gender, body size and composition, age, and the mode of the exercise (16). A person’s VO2 max is the gold standard of assessing …
