International Journal of Exercise Science 8(2): 154-163, 2015. The purpose of this investigation was to determine if there are changes in metabolic markers of bone turnover within the 24-hour period following an acute bout of jogging or water exercise. Ten healthy females (2230 yr.) underwent three trials with different ground impact forces: jogging, water aerobics and control. For the jogging ...

objectives: the purpose of this study was to consider the effect of eight weeks aerobic training on pth, albumin, calcium, alkaline phosphatesand estrogen levels in postmenopausal women. methods & materials: 22 postmenopause women, 55-70 years, of jahandidegan center in tehran were selected and randomly divided into two groups: (experimental (12) and control (10)) .they had aerobic training pro...

Communicative behaviors are a very important aspect of human behavior, and deserve special attention when simulating groups and crowds of virtual pedestrians. Previous approaches have tended to focus on generating believable gestures for individual characters and talker-listener behaviors for static groups. In this paper, we consider the problem of creating rich and varied conversational behavi...

As our interactions with computing continue to expand off the desktop, we want to use mobile devices in many, if not all, of our everyday activities. However, the touch screen and physical button centric interfaces of today’s mobile devices offer relatively poor support for interaction in many situations where computing is not our primary task. For example, when wearing gloves in the cold, a mo...

Running performance, energy requirements and musculoskeletal stresses are directly related to the action-reaction forces between the limb and the ground. For human runners, the force-time patterns from individual footfalls can vary considerably across speed, foot-strike and footwear conditions. Here, we used four human footfalls with distinctly different vertical force-time waveform patterns to...

The purpose of this study was to examine the differences in physical performance and game-specific skill demands between 5 positional groups in a professional rugby league team. Positional groups consisted of the backs (n = 8), forwards (n = 8), fullback (n = 7), hooker (n = 8), and service players (n = 8). Time-motion analysis was used to determine physical performance measures (exercise inten...

Epidemic levels of inactivity are associated with chronic diseases and rising healthcare costs. To address this, accelerometers have been used to track levels of activity. The Fitbit and Fitbit Ultra are some of the newest commercially available accelerometers. The purpose of this study was to determine the reliability and validity of the Fitbit and Fitbit Ultra. Twenty-three subjects were fitt...

This paper presents a framework for view-invariant action recognition in image sequences. Feature-based human detection becomes extremely challenging when the agent is being observed from different viewpoints. Besides, similar actions, such as walking and jogging, are hardly distinguishable by considering the human body as a whole. In this work, we have developed a system which detects human bo...

The aim of the study was to analyse the inter-individual differences concerning the velocities at which changes in movement pattern occurred. During the FIFA World Cup Final in 2006 20 players were observed. For every player the individual velocity boarders were obtained for the movement patterns walking, jogging, cruising and sprinting. Comparisons were done between common velocity boarders an...
