In this initial study it is investigated the possibility of using simple artificial neural network for classification of kick techniques based on their specific force course profile. The aim is to investigate whether the neural networks could be a suitable tool for such task and can be possibly used in following research that will deal with classification of punch techniques and also the strike...

We investigated the effects of synchronizing kick frequency with the beat of a metronome on kinematic and electromyographic (EMG) parameters during the underwater dolphin kick as a pilot study related to the research that entitled "Effect of increased kick frequency on propelling efficiency and muscular co-activation during underwater dolphin kick" (Yamakawa et al., 2017) [1]. Seven collegiate ...

Recent observations of pulsar wind nebulae and radio polarization profiles revealed a tendency of the alignment between the spin and velocity directions in neutron stars. We study the condition for spin-kick alignment using a toy model, in which the kick consists of many off-centered, randomly-oriented thrusts. Both analytical considerations and numerical simulations indicate that spin-kick ali...

In recent years, data analytics has been a growing phenomenon in many fields, including sport, and there has been an increased focus on how technology will impact the work of coaching and performance professionals. This paper provides a reflection of the use of data analytics within the Gaelic Athletic Association’s (GAA) football coaching practice in Ireland, and evaluates for coaches how to e...

The objective of this study was to examine the relationship between stroking technique parameters and leg kick quantity in 100 m front crawl swim. Ten New South Wales Sydney Metropolitan swimmers were examined (14.1 ± 1.09 years). The investigation was performed during 100 meter swimming (average speed 1.35 ± .04 [m.s-1]) commencing from water at 50 m outdoor pool. Stroke length (SL), Stroke ra...

The first purpose of the study was to investigate biomechanical characteristics of eight different Taekwondo kicks and to categorize them by the newly defined index of coordination of hip and knee joint motions. The second purpose was to investigate the effect of the rhythmic hop (habitually performed by athletes in Taekwondo sparring) in order to find whether rhythmic hop improves kicking perf...

The purpose of this study was to investigate the effect of foot movement on the instantaneous COM velocity changing during kick movement for elite female breaststroke swimmers. Nine elite swimmers swam at their maximal effort in a 25-m pool. The swimming motions were recorded with the motion capture system. The COM velocity generated by kick movement was not related the foot velocity. In contra...

The paper discusses the addition of off-task socially oriented conversational abilities to an existing “teachable agent” (TA) in an educational game in mathematics. The purpose of this extension is to affect constructs known to promote learning, such as self-efficacy and engagement as well as enhance students’ experiences of interacting with the game. A comparison of students that played the ga...

This study investigated the number of trials necessary to obtain optimal biomechanical responses in 10 consecutive soccer instep kicks. The kicking motions of dominant legs were captured from 5 experienced and skilled adult male soccer players (height: 184.60 ± 4.49 cm; mass: 80 ± 4.24 kg; and age: 25.60 ± 1.14 years) using a 3D infrared high-speed camera at 200 Hz. Some of the important kinema...
