From: Effects of balance training on balance performance in youth: role of training difficulty
Performance changes (mean ± standard deviation) during the intervention period in proactive balance (i.e., A: anterior reach distance in the Y-Balance Test; B: Functional Reach Test distance) for the BT-low compared to the BT-high group. BT-low = balance training using a low level of task difficulty; BT-high = balance training using a high level of task difficulty; LL = leg length
