We introduce a toy model of the “rat race” in which individuals try to better themselves relative to the rest of the population. An individual is characterized by a real-valued fitness and each advances at a constant rate by an amount that depends on its standing in the population. The leader advances to remain ahead of its nearest neighbor, while all others advance by an amount that is set by ...

This study examined how supine-to-stand (STS) performance is related to process and product assessment of motor competence (MC) in children. Ninety-one children aged 5–9 years were assessed for process and product MC (10 m running speed and standing long jump) as well as process and product measures of STS. Tertiles were created for STS process and STS product scores to create 3 groups reflecti...

Relationships between anthropometric dimensions (stature, weight, arm and calf circumferences, and four subcutaneous skinfolds), and motor performances (dash, standing long jump, throw for distance and grip strength) were considered in 348 mild-to-moderately undernourished Senegalese children 5-13 years of age (168 boys and 180 girls). Weights and statures are, on average, below the National Ce...

The long-standing issue of the competition between the magnetic field and the Kondo effect, favoring, respectively, triplet and singlet ground states, is addressed using a cluster slave-rotor mean-field theory for the Hubbard model and its spin-correlated, spin-frustrated extensions in two dimensions. The metamagnetic jump is established and compared with earlier results of dynamical mean-field...

Children with the developmental coordination disorder have difficulties in performing several movement tasks. The present study examined the role of the developmental coordination disorder in children’s physical fitness in the context of Greek primary education. One hundred fifty-four pupils participated in the study. The Movement Assessment Battery for Children was used to assess their motor c...

background: standing workstation can be a strategic approach for many electronics manufacturers to achieve work optimization. however, the well-being of the workers has become a great issue for both workers and employers. the main objective of this research was to study the effects of standing working posture on the workers and their impact to workers’ health and productivity and then to re-des...

This study investigated whether intellectual potential, personality, and physical fitness at recruitment predicted success in police students (future officers), biological sex influenced these factors. The potential (high school Serbian language test), personality traits (Big Five), abilities (standing long jump, push-ups 10-seconds, 30-seconds sit-ups, 12-min Cooper running test, a whole body ...

Physical preparation of female volleyball players plays a big part in achieving maximum goals both personal and team. Successful selection means methods the preparatory period general stage significant role proper physical preparation. The goal research was to determine state development motor skills that are special qualified players. Material methods. Using generalizations, systematization, a...
