Racing 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...

Competitive 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...

Head Starts in Contests

This paper studies equilibrium behavior in a class of games that models asymmetric multiprize competitions in which players’ costs are not necessarily strictly decreasing. Such costs accommodate head starts, which capture incumbency advantages, prior investments, and technological differences. I provide an algorithm that constructs the unique equilibrium in which players do not choose weakly-do...

the effect of the utilization of electronic dictionaries on depth and breadth of vocabulary knowledge: a case of iranian efl learners

مطالعه حاضر تلاشی است برای بررسی تأثیرات به کارگیری فرهنگ لغات ، یکی از مهمترین ابزارهای یادگیری واژگان درفراگیری زبان خارجی، بر روی دانش لغوی. دراین تحقیق فرهنگ های الکترونیکی در قیاس با فرهنگ های چاپی مورد بررسی قرارگرفته اند که آیا این فرهنگ ها تاثیرقابل توجهی بر روی دوبعد کمی و کیفی دانش لغوی یعنی عمق و گستره لغات می گذارند. همچنین مشخص گردیده است که آیا تفاوت قابل ملاحظه ای میان عمق و گستر...

Sequential all-pay auctions with head starts

We study a sequential all-pay auction where heterogeneous contestants are privately informed about a parameter (ability) that a¤ects their cost of e¤ort. In the case of two contestants, contestant 1 (the …rst mover) makes an e¤ort in the …rst period, while contestant 2 (the second mover) observes the e¤ort of contestant 1 and then makes an e¤ort in the second period. Contestant 2 wins the conte...
