Motor fitness , particularly balance , was the most studied fitness component , while cardiorespiratory fitness was the least studied .
While we wait for more evidence to be accumulated in preschool children , the PREFIT battery hereby proposed is a useful tool for assessing physical fitness in children aged 3–5 years
Background Physical fitness is a powerful health marker in childhood and adolescence , and it is reasonable to think that it might be just as important in younger children , i.e. preschoolers .
At the moment , research ers , clinicians and sport practitioners do not have enough information about which fitness tests are more reliable , valid and informative from the health point of view to be implemented in preschool children .
Objective Our aim was to systematic ally review the studies conducted in preschool children using field-based fitness tests , and examine their ( 1 ) reliability , ( 2 ) validity , and ( 3 ) relationship with health outcomes .
Our ultimate goal was to propose a field-based physical fitness-test battery to be used in preschool children .
After analyzing the information retrieved in the current systematic review about fitness testing in preschool children , we propose the PREFIT battery , field-based FITness testing in PREschool children .
Improvements in fitness reduce the risk of becoming overweight across puberty.
PURPOSE Information about factors related to overweight development in early stages of life is needed for design ing useful strategies to prevent overweight and related diseases . Longitudinal studies can contribute to this goal . The present study aim ed to identify factors in childhood that determine the development of overweight/obesity in adolescence . METHODS A prospect i ve study in 598 normal-weight Estonian and Swedish children age 9.5 ± 0.4 yr from the European Youth Heart Study , who were followed during 6 yr , was conducted . Weight and height were measured at baseline and follow-up , and weight status was ascertained according to the international criteria for body mass index . Cardiorespiratory fitness  ( expressed as  VO(2max ) ( mL·kg(-1)·min(-1 ) ) ) was assessed by a maximal bike test . Parents reported their weight , height , and educational level . RESULTS Being male ( vs female ) and Estonian ( vs Swedish ) was related to higher risk for incident overweight/obesity . Change in fitness was a stronger predictor of incident overweight/obesity than childhood fitness , parental overweight , or parental education . The risk of developing overweight/obesity was reduced 10 % every 1 mL·kg(-1)·min(-1 ) of VO(2max ) increase ( odds ratio = 0.90 and 95 % confidence interval = 0.84 - 0.95 ) after adjustment for a set of confounders including baseline body mass index and without differences by gender . CONCLUSIONS Our results suggest that improvements in fitness from childhood to adolescence are associated with a lower risk of becoming overweight/obese in adolescence . The current findings highlight the importance of promoting fitness through physical exercise from early stages in life , as a promising strategy to fight against overweight and obesity . Gender and country differences observed in this study require social and political attention
