The maturation of the fitness movement has brought with it an increasingly sophisticated consumer that has become concerned with the stress which activities such as jogging or running impose on the body. In order to maintain and improve their level of fitness, many in this group have sought out new modalities that provide the desired training stimulus but with reduced wear and tear. To meet thi...

This paper presents a system for 3D Pose estimation of cyclic activities (e.g. walking, jogging). Principal Component Analysis is used to compress the high dimensional space of poses. Human activities are encoded by Hidden Markov Models, overlaid on Gaussian Mixture Models. A generative approach based on the Annealed Particle Filter is used to estimate poses from silhouettes derived by a monocu...

In this paper, we are interested in looking for Hopf bifurcation solutions for mathematical model of plasma glucose and insulin during physical activity. The mathematical model is governed by a system of delay differential equations. The algorithm for determining the critical delays that are appropriate for Hopf bifurcation is used. The illustrative example is taken for a 30 years old woman who...

A 43 year old man presented to the accident and emergency department with a history of feeling light headed followed by loss of consciousness after he had just finished jogging. There was no associated chest pain, palpitations, or seizure activity. He admitted to feeling dizzy and presyncopal almost every time after performing any strenuous exercise. Physical examination and blood investigation...

The elevation gain is an important contributor to the total workload in endurance sports. The purpose of this study was to evaluate the influence of the arm swing on elevation gain in three sport watches (Garmin® Forerunner 910XT, Polar® RS800CX and Suunto® Ambit2) on a flat 400 m outdoor track. Altogether, a total of 120 repetitions of 1,200 m were performed at self-selected speeds correspondi...

The study established characteristics of practices and practitioners of leisure-time physical activities among adults in Florianopolis, Brazil. It was a population-based, cross-sectional survey conducted between September 2009 and January 2010. Leisure-time physical activity was assessed using a validated questionnaire. Walking and weight lifting were the most frequently reported activities. Vi...
