Analysis of determinants of swimming economy in front crawl
European Journal of Applied Physiology and Occupational Physiology, 1990 The purpose of this study was to investigate the relationship between swimming economy, energy cost to move the body per unit distance (CS) at a given velocity (v) and the potential determinants, i.e. performance level, body size, swimming technique and v. A total of 101 males were studied.

Controlled‐frequency breath swimming improves swimming performance and running economy
Scandinavian Journal of Medicine & Science in Sports, 2013 Respiratory muscle fatigue can negatively impact athletic performance, but swimming has beneficial effects on the respiratory system and may reduce susceptibility to fatigue. Limiting breath frequency during swimming further stresses the respiratory system through hypercapnia and mechanical loading and may lead to appreciable improvements in ...

Economy and efficiency of swimming at the surface with fins of different size and stiffness
European Journal of Applied Physiology, 2005 The aim of this study was to investigate how fins with varying physical characteristics affect the energy cost and the efficiency of aquatic locomotion. Experiments were performed on ten college swimmers who were asked to swim the dolphin kick while using a monofin (MF) and to swim the front crawl kick with a small-flexible fin (SF), a large-stiff fin (

Swimming Strategies for Energy Economy
, 2010 The laws of physics are rigid and fixed. Animals, therefore, are restricted in their use of available energy in accordance to the constraints of mechanics and thermodynamics. Evolutionary success dictates that a large proportion of the available energy reserves be allocated to reproductive effort despite the demand by other energy consuming functions ...

Effects of Arms-Only Swimming Training on Performance, Movement Economy, and Aerobic Power
International Journal of Sports Physiology and Performance, 2008 Context:Forward propulsion in freestyle swimming is predominantly achieved through arm action. Few studies have assessed the effects of arm training on arm power and swimming performance, yet there have not been any investigations on the effects of arms-only swimming training on swimming performance and physiological responses to arm exercise.Purpose ...

Comparative Biochemistry and Physiology Part A: Physiology, 1991 Abstract 1. 1. The burst-and-coast behavior and tail beat frequency were analysed to determine if an energetic saving was realized for fish when swimming in formation. 2. 2. Individual Notemigonus crysoleucas were compared as they swam singly or in a school of five at 0.15 m/sec in a flow tank. 3. 3. No significant difference was found in

How dorsal fin sharpness affects swimming speed and economy
Journal of Fluid Mechanics, 2019 Multi-fin systems, like fish or fish-inspired vehicles, are governed by unsteady three-dimensional interactions between their multiple fins. In particular, dorsal/anal fins have received much attention because they are just upstream of the main thrust-producing fin: the caudal (tail) fin.

ENERGY ECONOMY IN SPORTS HALLS AND SWIMMING POOLS IN ROCK
, 1981 In Norway, during the last decade, several dual purpose rock installations have been constructed. In time of peace they are serving as sports halls and swimming pools and in war events as public shelters. Running experiences have shown remarkable low energy consumption and maintance costs compared to conventional installations.
