Biomechanical analysis of the swim-start: a review.
This review updates the swim-start state of the art from a biomechanical standpoint. We review the contribution of the swim-start to overall swimming performance, the effects of various swim-start strategies, and skill effects across the range of swim-start strategies identified in the literature. The main objective is to determine the techniques to focus on in swimming training in the contempo...
متن کاملCompetitive Swimmers Modify Racing Start Depth Upon Request
To expand upon recent findings showing that competitive swimmers complete significantly shallower racing starts in shallower pools, 12 more experienced and 13 less experienced swimmers were filmed underwater during completion of competitive starts. Two starts (1 routine and 1 “requested shallow”) were executed from a 0.76 m block height into water 3.66 m deep. Dependent measures were maximum he...
متن کاملRacing Start Safety: Head Depth and Head Speed During Competitive Starts Into a Water Depth of 1.22 m
From the perspective of swimmer safety, there have been no quantitative 3-dimensional studies of the underwater phase of racing starts during competition. To do so, 471 starts were filmed during a meet with a starting depth of 1.22 m and block height of 0.76 m. Starts were stratified according to age (8 & U, 9–10, 11–12, 13–14, and 15 & O) and stroke during the first lap (freestyle, breaststrok...
متن کاملCompetitive Safety Strategies in Position Auctions
We attempt to address the challenge of suggesting a useful bidding strategy to an agent in the an ad auction setting. We explore the possibility of using competitive safety strategies in that context; aC-competitive strategy guarantees a payoff which is no less than a factor of C of the payoff obtained in a best Nash equilibrium. We adopt the model of ad auctions suggested by Varian and provide...
متن کاملA multistage shuttle swim test to assess aerobic fitness in competitive water polo players.
A 10m multistage shuttle swim test (MSST) was designed for the assessment of aerobic fitness of competitive water polo players. Test-retest reliability was determined using a sample of 22 female and 22 male trained water polo players. An intraclass correlation coefficient of 0.99 (p>0.05) was calculated between the two test scores. The technical error of measurement for the test was 2.3 shuttle...
