Introduction H school, university, and professional sports teams often devote considerable resources (human and capital) to quantify an athlete’s sport potential and to train individuals to improve athletic performance. Athleticism is computed not simply by the points scored or tackles achieved, but also through metrics that eliminate the need to compensate for different levels of competition a...

Previous research has reported the validity and reliability of a range of field-based tests of children's cardiorespiratory fitness. These two criteria are critical in ensuring the integrity and credibility of data derived through such tests. However, the criterion of scalability has received little attention. Scalability determines the degree to which tests developed on small samples in contro...

For children and adolescents with cerebral palsy (CP) classified as Gross Motor Function Classification System (GMFCS) level III there is no running-based field test available to assess their cardiorespiratory fitness. The current study investigated whether a shuttle run test can be reliably (test-retest) performed in a group of children with spastic diplegia (eight male, five female) classifie...

This study examined the association between physical abilities, anthropometric characteristics and artistry performance scores in Greek, national level, competitive rhythmic gymnasts. Forty-six preadolescent gymnasts (aged 9.9±1.3 years) underwent a series of physical fitness (balance, flexibility, muscular power and endurance, sport-specific high intensity shuttle run performance) and anthropo...

The aims of the present study were to assess gender differences regarding lactate threshold and intermittent shuttle run performance in female and male soccer players as well as to investigate the relationships between both endurance characteristics in both genders. Fourteen female (1(st) division) and thirteen male (4(th) division) soccer players completed an incremental test (IT) to determine...

The purpose of this study was to evaluate changes in anaerobic endurance in elite First-league soccer players throughout 2 consecutive seasons, in 2 phases, with and without high-intensity situational drills. Eighteen soccer players were tested before and after the 8-week summer conditioning and again in the next season. The measured variables included 300-yard shuttle run test, maximal heart r...
