Evidence of balance training‐induced improvement in soccer‐specific skills in U11 soccer players

The present study aim was to determine the role of balance training in improving technical soccer skills in young players. Two U11 soccer teams were randomly assigned one to either balance training (BT; n=22) or control group (Ctrl; n=21). At the end of their habitual soccer training (identical in BT and Ctrl), BT underwent additional balance training for 12 weeks (3sessions/week, 20 min per session), while Ctrl had a 20\u2010min scrimmage. Before and after the intervention, BT and Ctrl underwent two soccer\u2010specific tests (Loughborough Soccer Passing, LSPT, and Shooting, LSST, Tests), and bipedal and unipedal balance evaluations. After intervention, both groups decreased the trials time and improved passing accuracy, with larger improvements in BT than Ctrl [LSPT penalty time (CI95%): \u20102.20 s (\u20102.72/\u20101.68); ES (CI95%): \u20102.54 s (\u20103.34/\u20101.74)]. Both groups improved balance ability, with BT showing larger increments in bipedal tests than Ctrl [static balance: \u201029 mm (\u201042/\u201016); ES: \u20101.39 (\u20102.05/\u20100.72); limit of stability: 4% (3/5); ES 3.93 (2.90/4.95); unipedal quasi\u2010dynamic balance: 0.07 a.u. (0.03/0.11); ES: 1.04 (0.40/1.67) and active range of motion: \u20105% (\u20108/\u20102); ES \u20100.89 (\u20101.51/\u20100.26)]. Low\u2010to\u2010moderate correlations between the players\u2019 technical level and unipedal balance ability were retrieved, particularly in the non\u2010dominant limb (R from 0.30 to 0.48). Balance training improved some technical soccer skills more than habitual soccer training alone, suggesting that young soccer players may benefit from additional balance training added to their traditional training
