METHOD Using a prospective cohort design, individuals with documented cases of childhood physical and sexual abuse and neglect (processed during 1967-1971) and a matched ...

BACKGROUND The purpose of the present study is to compare the radiological parameters of the spino-pelvic sagittal alignment in young elite skiers and non-athletes of a similar age. METHODS The sample group (n = 102) consisted of elite Alpine and Mogul skiers (n = 75) and a non-athletic population (n = 27), mean age for both groups was 17.7 (±1.4) years (skiers mean age 18.3 SD 1.1 and contro...

The purpose of this study was to investigate the relation between training load, recovery and monthly field test performance in young elite soccer players in order to develop training guidelines to enhance performance. In a prospective, nonexperimental cohort design, eighteen young elite soccer players registered training and match duration for a full competitive season by means of daily traini...

The purpose of this study was to investigate the relation between training load, recovery, and monthly field test performance in young elite soccer players to develop training guidelines to enhance performance. In a prospective, nonexperimental cohort design, 18 young elite soccer players registered training and match duration for a full competitive season by means of daily training logs. Furth...

At present, little is known about elite schoolboy rugby players in South Africa and internationally. To obtain the profile of elite schoolboy rugby players, young players must be tested and monitored to compile norms for them. The aim of this study was to identify the characteristics of the elite U 16 and U 18 schoolboy rugby players in South Africa with reference to anthropometric variables, p...

BACKGROUND Static stretching (SS) is a recovery intervention used for the reduction of muscle soreness postexercise. The effects of SS on elite young footballers have received little attention, and therefore the aim of this study was to assess the effects of SS on muscle recovery following competitive soccer matches in elite young footballers. METHODS Ten male participants (16±1 years) were r...

Fast bowling in cricket is an activity that is well recognised as having high injury prevalence and there has been debate regarding the most effective fast bowling technique. The aim of this study was to determine whether two-year coaching interventions conducted in a group of elite young fast bowlers resulted in fast bowling technique alteration. Selected kinematics of the bowling action of 14...

The mouthbrooding cichlid Tropheus moorii exhibits an exceptional degree of maternal investment. Females produce very large eggs, which are incubated for a period of six weeks, and they feed their young in the mouth while starving themselves. Only very few fish species are known to feed their young. We hypothesized that feeding may either (1) benefit females directly if young develop faster, or...
