Objective: To investigate the relationship between anthropometrics and sprint and agility performance and describe the development of sprint (acceleration) and agility performance in 10- to 16-year-old male soccer players. <p>Methods: One hundred and thirty-two participants were divided into three age groups, 10–12 years (mean 10.8±0.50), 13–14 years (mean 13.9±0.50), and 15–16 years (mean 15.5±0.24), ...

Several studies in recent years have reported significant fitness improvements in children after exercise interventions, given sufficient training intensity, frequency and duration. However the knowledge of how fast children respond to exercise is limited and most research protocols are performed on cycle ergometers or other training devices using exercise programs are not applicable for practical ...

The level of motor competence for six-year-old children are of special interest because at this age they have started at school, and they have to master new requirements. Ninety-four children were tested in fine- and gross- motor skills, by the Movement ABC test. Within the fifth percentile of the USA norms, 9.6 % of the children would have to be classified as to have motor problems, with 11.7% ...

Longer distance cross-country ski (14–220 km) races such as the Visma Ski Classics (VSC) has recently gained attention in addition to the traditional Olympic distances (5–50 km) associated with cross-country (XC) skiing. These long-distance races are characterized by extensive use of the upper body while double poling (DP). While there is a substantial amount of research on Olympic distance XC skiing, ...
