Four Weeks of Goal-Directed Learning in Primary Physical Education Classes.

Relatively little is known about how practice relates to children's improvement in gross motor skill performance. The aim of this study is to determine to what extent 6- and 7-year-old children improve their gross motor skill performance in a four-week period, in which goal-directed learning is stimulated and to determine whether differences between boys and girls occur. Groups of 6 year olds (n = 167) and 7 year olds (n = 140) practiced their gross motor skill for four weeks.

Knowing what to do and doing it: differences in self-assessed tactical skills of regional, sub-elite, and elite youth field hockey players.

To determine whether youth athletes with an "average" (regional), "high" (sub-elite), and "very high" (elite) level of performance differ with respect to their self-assessed tactical skills, 191 youth field hockey players (mean age 15.5 years, s = 1.6) completed the Tactical Skills Inventory for Sports (TACSIS) with scales for declarative ("knowing what to do") and procedural ("doing it") knowledge.

Tactical skills of world-class youth soccer teams.

In this study, we examined the relationship between tactical skills and competitive standard of two youth soccer teams by comparing 18 players (age 18-20 years) from the Dutch and 19 players (age 18-23 years) from the Indonesian national youth team. All players completed the declarative and procedural knowledge scales of the Tactical Skills Inventory for Sport (TACSIS). Multivariate analyses of variances and effect sizes were conducted to assess between- and within-team differences.
