Coordinated motion in a group of simulated critters can evolve under selection pressure from an appropriate fitness criteria. Evolution is modeled with the Genetic Programming paradigm. The simulated environment consists of a group of critters, some static obstacles, and a predator. In order to survive, the critters must avoid collisions (with obstacles as well as with each other) and must avoi...

We present experiments in which a group of autonomous mobile robots learn to perform fundamental sensor-motor tasks through a collaborative learning process. Behavioural strategies, i.e. motor responses to sensory stimuli, are encoded by means of genetic strings stored on the individual robots, and adapted through a genetic algorithm (Mitchell, 1998) executed by the entire robot collective: rob...

Purpose The purpose of this study was to examine whether physical activity, fitness, and motor skills have an indirect association with math performance via cognitive outcomes if so, through which aspects cognition? Methods This comprised 311 6th–9th grade adolescents (12–17 years [M age = 14.0 years], 59% girls) from seven schools throughout Finland in 2015. Math measured a teacher-rated achie...

Physical fitness and motor skills are considered important attributes for the military, affecting their professional performance. The high physical psychological demand that special forces subjected to requires acquisition of a set volitional such as resilience, effort, perseverance, or resistance frustration, which worthy further research. This study aimed analyse perception troops (commandos)...

BACKGROUND Animal studies indicate forced exercise (FE) improves overall motor function in Parkinsonian rodents. Global improvements in motor function following voluntary exercise (VE) are not widely reported in human Parkinson's disease (PD) patients. OBJECTIVE The aim of this study was to compare the effects of VE and FE on PD symptoms, motor function, and bimanual dexterity. METHODS Ten ...

The differences in human motor development are determined by predispositions and living conditions. The aim of the present study was to examine relationships between motor fitness of children and adolescents aged 8-16 years (277 boys and 247 girls), and their somatic build and quality of life of their families. Body height, body mass and skinfold thickness were measured. On the basis of these m...

this review based upon studies searched from the major scientific libraries has the objective of clarifying what is fitness training in modern days, the implications that it has on health in both youth and elderly and finally discuss fitness training practical implications.the prisma statement was partially adopted and a number of 92 items were selected, according to the inclusion criteria. res...

objectives: the aim of this study was to investigate the effects of mountaineering on health factors in elder people. methods & materials: this study was a cross-sectional study. forty three elderly men (mean age 57/7±9/3 yrs) were selected randomly fromparks of northern tehran. according to their activity and type of activity, subjects divided into three groups of mountaineer (n=15), trained (...

Cardiorespiratory fitness assessment with leg cycle exercise testing may be influenced by motor impairments in the paretic lower extremity. Hence, this study examined the usefulness of a unilateral arm crank exercise test to assess cardiorespiratory fitness in individuals with stroke, including sixteen individuals with hemiparetic stroke (mean ± SD age, 56.4 ± 7.5 years) and 12 age- and sex-mat...

Physical fitness has been described as the ability to perform moderate to vigorous levels of physical activity without undue fatigue yet having ample energy to enjoy leisure time pursuits to meet unforeseen emergencies. Most frequently cited components of physical fitness are those related to health and those related to athletic skills [1]. The skill related components are important for various...
