This study explored how the number of allowed ball touches per player possession affected performance different age groups (U9, U11, U13, U15, U17 and U19) during a Gk + 4vs4+Gk small-sided games. Each day, players randomly performed following three conditions (for total 6 days): i) free-play (FP); ii) maximum 2 (2 T); iii) 1 touch (1 T). Players’ positional data was used to compute time-motion...

The link between the anticipation skills of cricket batsmen and their practice histories was examined. Skilled and lesser skilled batsmen of U15, U20, and adult age completed a temporal occlusion task, in which they were required to use prerelease kinematic information to predict the type and length of delivery being bowled, and a structured interview, in which their accumulated hours of experi...

Recent studies have provided empirical evidence on the prognostic relevance of objective performance diagnostics in soccer talent identification and development process. However, little is known about validity coaches' subjective evaluations performance. This study evaluated assessments within a nationwide program addressed motor, perceptual skill, personality-related factors. Male players ( N ...

ABSTRACT Introduction: Although competitiveness rises progressively increases according to age groups, players must stand out in their playing position at all ages win a spot on National Teams.

Dynemicin is a novel anthraquinone-fused member of the 10-membered enediyne antitumor antibiotic family. The development of a genetic system for the dynemicin producer Micromonospora chersina confirmed, for the first time, the requirement of the putative enediyne core biosynthetic genes (dynE8, U14 and U15) and a tailoring oxidase gene (orf23) for dynemicin production. Cloning and sequence anal...
