The left hand second to fourth digit ratio (2D:4D) is not related to any physical fitness component in adolescent girls.

Introduction: The second to fourth-digit-ratio (2D:4D), a putative marker of prenatal androgen action and a sexually dimorphic trait, has been suggested to be related with fitness and sports performance, although results are not univocal. Most studies however focus on a single aspect of physical fitness or one sports discipline.

Methods: In this study the 2D:4D ratio of 178 adolescent girls (age 13.

Prospective control abilities during visuo-manual tracking in children with 22q11.2 Deletion syndrome compared to age- and IQ-matched controls.

To examine whether children with a 22q11.2 Deletion syndrome (22q11.2DS) are able to use prospective control, 21 children with 22q11.

Kinematic movement strategies in primary school children with 22q11.2 Deletion Syndrome compared to age- and IQ-matched controls during visuo-manual tracking.

The present study focused on the mechanism subserving the production of kinematic patterns in 21 children with 22q11.2DS (mean age=9.6+/-1.

Static and dynamic visuomotor task performance in children with acquired brain injury: predictive control deficits under increased temporal pressure.

Objective: To compare performance of children with acquired brain injury (ABI) on static versus dynamic visuomotor tasks with that of control children.

Participants: Twenty-eight children with ABI and 28 normal age- and gender-matched controls (aged 6-16 years).

Main Measures: Two visuomotor tasks on a digitizing tablet: (1) a static motor task requiring tracing of a flower figure and (2) a dynamic task consisting of tracking an accelerating dot presented on a monitor.

The motor profile of primary school-age children with a 22q11.2 deletion syndrome (22q11.2DS) and an age- and IQ-matched control group.

In the early publications on the 22q11.2 Deletion Syndrome (22q11.2DS) motor abnormalities have been frequently reported.

Motor development in school-aged children with 22q11 deletion (velocardiofacial/DiGeorge syndrome).

The aim of this study was to compare the motor development of primary school children (age 5-14y) with a 22q11 deletion (del22q11) group and a control group. The effects of a congenital heart defect (CHD) and IQ on motor development were additionally studied within the del22q11 group. Motor development of 37 children with a del22q11 (20 males, 17 females; mean age 9y 4mo, range 5y 9mo-13y 3mo) and 34 controls (23 males, 11 females; mean age 9y 1mo, range 4y 8mo-13y 6mo) was assessed with the Bruininks-Oseretsky Test of Motor Proficiency.

Maturity offset in gymnasts: application of a prediction equation.

Purpose: To verify the applicability of the prediction equation for maturity offset in a sample of female gymnasts followed longitudinally through adolescence.

Methods: Fifteen gymnasts were followed longitudinally for 6-7 yr across adolescence. Weight, height, and sitting height were measured at annual intervals.
