In this paper, a generic architecture based on the Transferable Belief Model (TBM) is proposed for on line and automatic human action and activity recognition in videos of athletics sports with moving camera. The first contribution of this paper is a tool called Belief Scheduler which makes belief on actions smoother, separates actions states (true or false) and synchronizes actions in order to...

This intervention aimed to improve Badminton-specific functional performance of an elite under-19 player (18 years) via a single-weekly resistance and plyometric training (RPT) session for 8-weeks. The athlete’s ‘response-to’ and ‘withdrawal-from’ the RPT were assessed. The athlete (stature: 1.77 m, mass: 81.5 kg) completed the RPT intervention throughout a competitive season. Performance testi...

The problem of space-optimal jump encoding in the x86 instruction set, also known as branch displacement optimization, is described, and a linear-time algorithm is given that uses no complicated data structures, no recursion, and no randomization. The only assumption is that there are no array declarations whose size depends on the negative of the size of a section of code (Hyde 2006), which is...

We present an automatic human shape-motion analysis method based on a fusion architecture for human action and activity recognition in athletic videos. Robust shape and motion features are extracted from human detection and tracking. The features are combined within the Transferable Belief Model (TBM) framework for two levels of recognition. The TBM-based modelling of the fusion process allows ...

Aim: This study aimed to compare the MC levels of Brazilian and Portuguese schoolchildren from 4 11 years. Methods: One hundred forty-eight children were evaluated using Motor Competence Assessment (MCA) instrument later compared existent normative values for a similar age range. Results: Our findings showed that increased with age, boys outperformed girls, especially in older group. The distri...

The purpose of this study was to determine the effects of agility training (training of acceleration, deceleration and quick change of the direction of movement) on athletic power performance. Eighty healthy male college students (age 19±1.1 years; body mass 77.2±7.1 kg; body height 180.1±7.1 cm; body fat percentage 10.8±1.6) participated in this study. The study was a randomized controlled tri...

A mechanical model is proposed which quantitatively describes the dynamics of the centre of gravity (c.g.) during the take-off phase of the long jump. The model entails a minimal but necessary number of components: a linear leg spring with the ability of lengthening to describe the active peak of the force time curve and a distal mass coupled with nonlinear visco-elastic elements to describe th...

The purpose of this study was to examine the effects of six weeks of depth jump (DJ) vs. countermovement jump (CMJ) training on sand on muscle soreness, jump, sprint, agility and leg press strength. Thirty healthy men (age 20.4±1.1 years; height 177.4±5.1 cm; mass 72.8±9.7 kg) volunteered to participate and were randomly assigned to one of three groups: DJ training group (n=10), CMJ training gr...
