Book Swimming Science

Download or read book Swimming Science written by G. John Mullen and published by University of Chicago Press. This book was released on 2018-07-27 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discover the secrets of physiology, hydrodynamics, and other scientific aspects of swimming to enhance your skills and speed! Low-impact, beneficial at any age, and just plain fun, swimming is an excellent workout—and the same scientific principles apply whether you’re competing for a medal or practicing your backstroke in the backyard. Each time you suit up and dive in, your body’s moving parts must work together to propel you through dozens of pounds of water resistance, somehow emulating the movements of species that evolved specifically for the water. What are the physical forces at work when you get in a pool, and what determines whether you will sink or swim? In this enlightening and useful volume, contributors break down every aspect of the sport. Swimming Science covers physiology, psychology, and safety, as well as hydrodynamics, nutrition, and technique. Each chapter examines these topics through a series of practical questions: *What are the forces acting on you when you swim, and how do your muscles best generate propulsion against those forces? *How much protein, salt, and iron should a swimmer consume, and how does energy from carbohydrates compare to energy from fats? *How important is the “swimmer’s physique” in competitive swimming, and is technique or strength more necessary for generating speed? These questions and more are examined with the aid of explanatory diagrams and illustrations. No matter whether you swim for exercise, enjoyment, or athletic achievement, Swimming Science adds a new dimension to the sport. “Swimming Science is a wonderful read for those interested in understanding how extraordinary athletes have been able to swim at incredible speed. But it is also an inspiring and potentially transforming read for ordinary people for whom swimming is simply a love story with the water.” —American Journal of Public Health

Book Effects of Different Types of Warm up on Swimming Performance in Collegiate Swimmers

Download or read book Effects of Different Types of Warm up on Swimming Performance in Collegiate Swimmers written by Gytis Balilionis and published by . This book was released on 2009 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the present study was to evaluate the effect of three different types of warm-up on swimming performance in NCAA Division I swimmers. Eight male and eight female swimmers utilized three warm-up protocols prior to performing 50-yard (45.72-meter) freestyle swim trials each trial in counterbalanced order and separated by 48 hours. The warm-up protocols consisted of: (1) no warm-up, (2) short warm-up (50-yards at 40% maximal effort and 50-yards at 90%), (3) regular warm-up (swimmers own pre-competition warm-up). Following the warm-up regimen, participants rested for three minutes and completed a 50-yard freestyle swim trial. Heart rate pre- and post- trial, diving distance, reaction time, post warm-up RPE, post 50-yard trial RPE, and stroke count were measured. Times for 50-yard swim were significantly (p = 0.03) different among warm-ups. Mean 50-yard time was significantly (p = 0.01) faster after regular warm-up (24.95 " 1.53 sec) compared to short warm-up (25.26 " 1.61 sec) and approached significance between no- and regular- warm-ups (p = 0.06); however, no significant difference was found between no- (25.19 "1.54 sec) and short warm-ups (p = 0.59) on 50-yard time. Individual data indicated that 19% of participants performed their best 50-yard time after short warm-up, 37% after no-, and 44% after regular warm-up. Heart rate was significantly (p = 0.01) higher after regular warm-up (100 " 13 b/min) compared to no warm-up (88 " 18 b/min) and approached significance between short- and regular warm-ups (p = 0.07); however, no significant difference was observed between no- and short warm-ups (92 " 19 b/min) (p = 0.32). RPE was significantly (p

Download or read book Effect of Different Warm ups and Upper body Vibration on Performance in Masters Swimmers written by Svetlana Nepocatych and published by . This book was released on 2009 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT The purpose of the study was to evaluate the effects of no, short, or regular warm-up and Upper-Body Vibration (UBV) only or UBV+ short warm-up on swimming performance in Masters Swimmers. Six females and four males, aged 24-50, healthy master swimmers volunteered to participate in the study. Participants completed all assigned warm-ups (no, short, regular, UBV-only, or UBV + short) in counterbalanced order, rested for three minutes and completed a 50-yard (45.7 m) freestyle maximal performance time trial. Rating of perceived exertion (RPE) and heart rate (HR) were measured post warm-up and post 50-yd time trial. No significant difference (p = 0.987) was found among no, short or regular warm-up regarding 50-yd freestyle time (29.0 " 3.7, 29.0 " 3.6, and 29.1 " 3.4 s, respectively). No significant difference (p = 0.563) was found among regular, UBV-only or UBV + short warm-ups regarding 50-yd freestyle time (29.1 " 3.6, 28.9 " 3.4, and 29.1 " 3.6 s, respectively). RPE after no warm up (6 " 0) was significantly lower compared to after short (13 " 2, p

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT The purpose of this study was to investigate the relationship between strength and power measures with sprint freestyle performance in Division 1 collegiate swimmers. Ten male subjects with an average age of 20.1 years (SD = 2.2) and eight female subjects with an average age of 19.4 years (SD = 1.3) participated in the study. The subjects performed a maximal-effort 45.72-meter freestyle swim test, a one-repetition-maximum (1-RM) weighted pull-up test, a non-countermovement jump (NCMJ), and a barbell back squat velocity test. The data distributions were normalized by creating Z-scores for each variable measured and the sum of the three-dryland tests The data were analyzed using Pearson product-moment correlation analysis. The results showed an inverse association between the sum of the three-dryland performance Z-scores and the 45.72-meter sprint swim time (r = -0.77, p

Book excerpt: Just one hundredth of a second separates elite swimmers from the podium, but what are the physical forces at work behind these tiny margins, and how can an understanding of them be used to improve your own technique in the pool? Swimming Science investigates, with each chapter focussing on a different area. From swimming technology, physiology, and psychology to hydrodynamics, the key principles of swimming science are addressed, with the content organised around a series of questions. What creates the drag in the water? How have swim suits evolved? Which muscles generate propulsion? How much force do elite swimmers use? Each question is investigated using up-to-date science and explanatory info-graphics.

Book Effect of Post activation Potentiation PAP on Swim Sprint Performance

Download or read book Effect of Post activation Potentiation PAP on Swim Sprint Performance written by Andrew P. Hancock and published by . This book was released on 2012 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose: This study examined post-activation potentiation (PAP) and its effect on performance during sprint swimming. Following resistance exercise, the muscles are in a potentiated, as well as a fatigued state. Potentiation dissipates faster than fatigue, creating a window of opportunity for possible performance enhancement. It was hypothesized that (1) there will be an improvement in sprint performance as a result of a PAP loading protocol, and (2) that there will be a significantly greater improvement in males as a result of a PAP loading protocol. Methods: Subjects were 30 members (males, N=15; females, N=15) of the Cleveland State University Swim Team. Subjects performed two swim trials in a randomized order. The control trial involved a standard 900 meter freestyle swim warm up, followed by 6 minutes rest, followed by a maximal 100 meter freestyle swim effort. The PAP trial involved the same protocol; however a PAP loading protocol was completed prior to the 6 minutes rest. The PAP loading protocol involved the subjects completing four maximal 10 meter swims at a 1 minute interval while attached to a resistive Power Rack. The load (L) for the swims was derived by the formula where LBM is the subjects'lean body mass and t is their best 100 meter freestyle time. Fifty meter splits were also analyzed, as well as blood lactates. A repeated measures ANOVA was used to analyze the differences between trials, as well as compare the gender response. Results: There was a significant improvement in 100 meter freestyle time (.54sec) for the PAP trial versus the control trial (p=.029). Both males and females improved during the PAP trial compared to the control trial for each performance measure: 100 meter, first 50 meter split, and last 50 meter, but there was no significant gender interaction (p=.647). Conclusion: PAP has been shown to enhance 100 meter freestyle performance in collegiate sprint swimmers. Males and females have shown a similar response to a PAP loading stimulus, although other methods for loading should be explored.
