Can balance training promote balance and strength in prepubertal children?

The prevalence of sustaining a fall is particularly high in children. Deficits in postural control and muscle strength are important intrinsic fall risk factors. Thus, the purpose of this study was to investigate the impact of balance training (BT) followed by detraining on postural control, plantar flexor strength, and jumping height in prepubertal children. Thirty grade 1 school children participated in this study and were assigned to either an intervention class (INT, n = 15, age 6.7 ± 0.5 years) or a control class (n = 15, age 6.6 ± 0.5 years). The INT participated in 4 weeks of BT (3 per week) integrated in their physical education lessons. Pre, post, and follow-up tests included the measurements of postural sway on a balance platform, maximal torque and rate of force development of the plantar flexors on an isokinetic device, and jumping height on a force platform. The significance level was set at p < 0.05. Balance training resulted in tendencies in terms of small to medium interaction effects yet not statistically significant improvements in postural sway (f = 0.14; p > 0.05), force production of the plantar flexors (f = 0.18; p> 0.05), and jumping height (f = 0.25; p> 0.05). Immaturity of the postural control system and deficits in attentional focus during practice of balance exercises could be responsible for the nonsignificant findings in this study. Thus, other training regimen (e.g., resistance training) should be applied alone or in combination with BT, which may have the potential to promote balance and strength in children.
