This study compared the conventional track and a new one-handed track start in elite age group swimmers to determine if the new technique had biomechanical implications on dive performance. Five male and seven female GB national qualifiers participated (mean ± SD: age 16.7 ± 1.9 years, stretched stature 1.76 ± 0.8 m, body mass 67.4 ± 7.9 kg) and were assigned to a control group (n = 6) or an intervention group (n = 6) that learned the new one-handed dive technique. All swimmers underwent a 4-week intervention comprising 12 ± 3 thirty-minute training sessions. Video cameras synchronized with an audible signal and timing suite captured temporal and kinematic data. A portable force plate and load cell handrail mounted to a swim starting block collected force data over 3 trials of each technique. A MANCOVA identified Block Time (BT), Flight Time (FT), Peak Horizontal Force of the lower limbs (PHF) and Horizontal Velocity at Take-off (Vx) as covariates. During the 10-m swim trial, significant differences were found in Time to 10 m (TT10m), Total Time (TT), Peak Vertical Force (PVF), Flight Distance (FD), and Horizontal Velocity at Take-off (Vx) (p < .05). Results indicated that the conventional track start method was faster over 10 m, and therefore may be seen as a superior start after a short intervention. During training, swimmers and coaches should focus on the most statistically significant dive performance variables: peak horizontal force and velocity at take-off, block and flight time.

An interventional study aimed at modifying some of the kinematic parameters identified in this study is necessary to determine which of these variables are best able to reduce kinetic outcomes clinically.

The nature of developmental coordination disorder (DCD) in a selected group of Singaporean children (n = 69) aged 6-9 years was investigated by two methods: an intergroup comparison of children with DCD and matched controls (n = 69), and an intragroup study on the same children with DCD in the search for subtypes within this group. The results from the two approaches demonstrate that while the children with DCD are clearly different from the control subjects, the difficulties seen within the DCD group are not common to all the children. Four identifiable subtypes were found within the children with DCD. This more specific information gained about the difficulties children with DCD experience is not easily established from the intergroup analysis, suggesting that the design of future intervention studies should incorporate differences found in subtypes of children with DCD.
