Children and adolescents who spend most of their time barefoot tend to develop motor skills differently and are better at jumping and balancing, scientists say. The study, published in the journal Frontiers in Pediatrics, is the first study to assess the relevance of growing up shod vs barefoot on jumping, balancing and sprinting motor performance during different stages of childhood and adolescence.
The study shows that habitually barefoot children are noticeably better at jumping and balancing compared to habitually shod children, particularly from 6-10 years of age.
While these beneficial barefoot effects diminished in older adolescents, the research nevertheless highlights the importance of barefoot exercise for motor development as children grow and mature.
"Walking barefoot is widely thought to be more natural, and the use of footwear has long been discussed as an influencing factor on foot health and movement pattern development," said Astrid Zech, a professor at University of Jena in Germany.
"A few studies report that barefoot situations change biomechanics in children and adults during running and jumping - but only limited knowledge exists for the clinical relevance of this finding," said Zech.
"We wanted to investigate, for the first time, whether changes in foot biomechanics due to barefoot activities are actually relevant for the development of basic motor skills during childhood and adolescence," she said.
Researchers assessed three motor skills - balance, standing long jump and a-20 metre sprint - in 810 children and adolescents from 22 schools across rural Western Cape South Africa and urban areas of northern Germany.
The two groups were selected to represent different footwear lifestyles: children from South Africa are habitually barefoot, while children from Germany wear shoes most of the time.
The habitually barefoot participants scored significantly higher in the balance and jumping tests compared to the habitually shod participants.
This difference was observed in both test conditions (barefoot and shod) and across all age groups (6-10, 11-14 and 15-18 years), but particularly evident in 6-10 year-old children.
The habitually barefoot children also performed better when barefoot than when shod.
"Most of the primary school children in our study (South Africa) go to school and perform sport and leisure activities barefoot," said Ranel Venter from Stellenbosch University, who led the South African research team.
"Our finding that these children performed better in balancing and jumping supports the hypothesis that the development of basic motor skills during childhood and adolescence at least partly depends on regular barefoot activities," said Venter.
Overall, the researchers' work emphasises the benefits of barefoot physical activities for motor development.
"Physical education classes, exercise and sport programs, and reactional activities that aim to improve basic motor skills could benefit from including barefoot activities," said Zech.
"Parents could also encourage regular barefoot time at home," she said.
