The main aim of the present investigation was to verify if the aerobic capacity (AC) measured in tethered swimming corresponds to the maximal lactate steady state (MLSS) and its correlation with 30 min and 400m free style swimming. Twenty-five swimmers were submitted to an incremental tethered swimming test (ITS) with an initial load of 20N and increments of 10N each 3min. After each stage of 3min, the athletes had 30s of interval to blood sample collections that were used to measure blood lactate concentrations ([La-]). The ACBI was determined by the abrupt increase in [La-] versus force (F). The points …

Injuries In Competitive Swimming: Incidence And Risk Factors, Kristin I. Chase
Theses and Dissertations
Objective: To study the nature and incidence rate of injuries that affect collegiate competitive swimmers and to examine the relationship between these injuries and specific risk factors. Background: Minimal research has been conducted on swimming-related injuries, with most studies being retrospective in nature. Only one study reported a calculated injury rate for athletic exposures. Past research reports that the shoulder is the most commonly injured location and that overuse injuries (e.g. tendonitis) is the most common injury type. Methods: IRB approval obtained through the University of North Dakota. Swimmers from UND swim team were asked to participate. Once consent was …

The dynamics of pulsed jetting in squids throughout ontogeny is not well understood, especially with regard to the development of vortex rings, which are common features of mechanically generated jet pulses (also known as starting jets). Studies of mechanically generated starting jets have revealed a limiting principle for vortex ring formation characterized in terms of a 'formation number' (F), which delineates the transition between the formation of isolated vortex rings and vortex rings that have 'pinched off' from the generating jet. Near F, there exists an optimum in pulse-averaged thrust with (potentially) low energetic cost, raising the question: do …
