How fins affect the economy and efficiency of human swimming
Journal of Experimental Biology, 2002 SUMMARYThe aim of the present study was to quantify the improvements in the economy and efficiency of surface swimming brought about by the use of fins over a range of speeds (v) that could be sustained aerobically. At comparable speeds, the energy cost (C) when swimming with fins was about 40 %lower than when swimming without them; when compared at ...

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.

Swimming economy (energy cost) and efficiency
, 2011 The energy cost per unit distance (i. e. the economy of swimming, C) is given by the ratio / v where is the net (above resting) metabolic power and v is the swimming speed. The contribution of the aerobic and anaerobic energy sources to in swimming competitions differs according to the distance covered; it is independent of swimming style, gender or ...

Neuromuscular control of trout swimming in a vortex street: implications for energy economy during the Karman gait [PDF]
Journal of Experimental Biology, 2004 SUMMARY Approximating the complexity of natural locomotor conditions provides insight into the diversity of mechanisms that enable animals to successfully navigate through their environment. When exposed to vortices shed from a cylinder, fishes hold station by adopting a mode of locomotion called the Kármán gait, whereby the body of

How dorsal fin sharpness affects swimming speed and economy
Journal of Fluid Mechanics, 2019Multi-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.

Swimming against the Current? Taxation of the Digitalized Economy in Latin America
Bulletin for International Taxation, 2019 In this article, the authors examine the various measures that eight Latin American countries have (and have not) implemented to tax profits derived from the digitalized economy in the region.

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

International Journal of Sports Medicine, 2005 The aim of the study was to verify whether an overloaded training (OT) in triathlon deteriorates running kinematics (RK) and running economy (RE). Thirteen well-trained male long-distance triathletes (age: 28.1 +/- 4.3 yrs; V.O (2max): 65.0 +/- 3.1 ml O (2) . min (-1) .
