“…Weight transfer time in AS condition was about 157-164 ms, which seemed to be shorter than 265 and 258 ms in young adults at cable loads of 15% and 20% body weight, respectively (Thelen et al, 1997). Nonetheless, the current results were more comparable with 147 and 157 ms in young and middle age adults, respectively, who recovered balance from maximum forward leaning (Carbonneau & Smeesters, 2014). In the study of Thelen et al (1997) cable loads of 15% and 20% body weight were equivalent to 13.5°and 17.3°lean angles, respectively (with detailed cable load to lean angle conversion in their study).…”

“…A commonly used method of testing balance recovery after a large postural perturbation is to release an individual from a static forward leaning position and have them attempt recovery with a single step 8–16. Madigan12 reported that muscle power generated during single-step recovery on the forward leaning task was lower in older compared to younger men.…”

Improving muscle strength and power may mitigate the effects of sarcopenia, but it is unknown if this improves an older adult’s ability to recover from a large postural perturbation. Forward tripping is prevalent in older adults and lateral falls are important due to risk of hip fracture. We used a forward and a lateral single-step balance recovery task to examine the effects of strength training (ST) or power (PT) training on single-step balance recovery in older adults. Twenty older adults (70.8±4.4 years, eleven male) were randomly assigned to either a 6-week (three times/week) lower extremity ST or PT intervention. Maximum forward (FLeanmax) and lateral (LLeanmax) lean angle and strength and power in knee extension and leg press were assessed at baseline and follow-up. Fifteen participants completed the study (ST =7, PT =8). Least squares means (95% CI) for ΔFLeanmax (ST: +4.1° [0.7, 7.5]; PT: +0.6° [−2.5, 3.8]) and ΔLLeanmax (ST: +2.2° [0.4, 4.1]; PT: +2.6° [0.9, 4.4]) indicated no differences between groups following training. In exploratory post hoc analyses collapsed by group, ΔFLeanmax was +2.4° (0.1, 4.7) and ΔLLeanmax was +2.4° (1.2, 3.6). These improvements on the balance recovery tasks ranged from ~15%–30%. The results of this preliminary study suggest that resistance training may improve balance recovery performance, and that, in this small sample, PT did not lead to larger improvements in single-step balance recovery compared to ST.

“…Older adults often appear to experience difficulty in responding to lateral balance perturbation [7][8][9][10][11][12][13][14] , and a number of these difficulties have been found to predict increased risk of falling in daily life [7][8][9][10][11] . Older adults tend to be less able than younger persons to maintain upright stance without exceeding their BOS stability limits, i.e.…”

“…Older adults tend to be less able than younger persons to maintain upright stance without exceeding their BOS stability limits, i.e. without stepping or grasping for support 12 . Furthermore, older adults often appear to experience difficulty when stepping in response to lateral perturbation, as evidenced by:(i) an increased likelihood of collisions between the stepping foot and the stance limb, (ii) a tendency to avoid crossover steps, and (iii) a higher incidence of multiple-step responses 7,8,11,13,14 .…”
