... trials of at least 20 m from which sagittal plane kinematics were obtained for the first four steps using inertial measurement units (200 Hz). Thigh-thigh, trunk-shank and shank-foot coordination was assessed using a modified vector coding and segment dominancy approach. Common coordination patterns...

.... It allows for tracking points efficiently without the need to click all individual frames. Videography Point digitization Tracking Kinematics Video recordings are of high relevance for scientific research in different fields. As technology advances, researchers make use of videography...

...Anthony B. Lapsansky; Jennifer A. Igo; Bret W. Tobalske ABSTRACT We investigated the effect of an added mass emulating a transmitter on the flight kinematics of zebra finches ( Taeniopygia guttata ), both to identify proximal effects of loading and to test fundamental questions regarding...

...Hibiki Kimura; Yuuki Kawabata ABSTRACT The kinematic and behavioral components of the escape response can affect the outcomes of predator-prey interactions. For example, because sensory perception range can have spatial bias, and because turn duration before the initiation of escape locomotion can...

... not exert influence on the energy storage. Once the overall length is determined, the ability of energy storage is ascertained. Hence, we may focus more on the asymmetry of the overall length of digits, rather than the proportion of phalanges. This paper builds an equivalent kinematic model...

... aquatic stage. In fact, the kinematic analyses showed that T. verrucosus uses lingual prehension to capture prey on land but changes to suction feeding for aquatic strikes. The statistical analyses revealed that terrestrial and aquatic strikes differ significantly in most kinematic parameters while...

... is a free and open source toolset for using consumer grade cameras to acquire 3D kinematic data in field settings. Videography Photogrammetry Kinematics Multiple cameras Calibration Many studies of biomechanics, animal behavior, evolution and ecology require that movement be quantified...

... representative of maximum performance. However, few studies have compared variability and repeatability in escape performances within and among individuals. Using the tropical damselfish Amblyglyphidodon curacao , we quantified inter- and intra-individual variation in behavioural and kinematic components...

... catfish found in South America. Field video observations reveal that their air-breathing behaviour consists of air-gulping at the surface, followed by a fast turn which re-directs the fish towards the bottom. Using high-speed video in the laboratory, we compared the kinematics of the turn immediately...

... production. I used high-speed video linked with simultaneous measurement of thrust production in tethered hatchlings, along with high-speed video of free swimming hatchlings swimming at different water speeds in a swim flume to investigate the links between kinematics of front flipper movement, thrust...

... traditional techniques. It is often the case that calibration is impossible and obtaining any quantitative kinematic data requires time consuming and relatively inaccurate approaches such as surveying the enclosure ( Channon et al., 2012 ) or using parallel lasers ( Rothman et al., 2008 ). 3D video...

...Rhea Von Busse; Anders Hedenström; York Winter; L. Christoffer Johansson Summary The morphology and kinematics of a flying animal determines the resulting aerodynamic lift through the regulation of the speed of the air moving across the wing, the wing area and the lift coefficient. We studied...
