“…To standardize participant stance position, the platform was marked with a 2-cm width tape to indicate the desired positioning of the feet. Participants were asked to keep their sight fixed at a mark on the wall positioned 1.5 m away from the platform and 1.5 m above floor level (Prado et al 2007;Duarte and Freitas 2010) and to breathe normally. Participants were on barefoot and were instructed to stand for 30 s on the force platform, with arms relaxed and with minimal body sway.…”

“…These parameters are considered as representative of the COP displacement providing information about the limits of stability of the body oscillations during a postural task, as well as the total trajectory around a median position during a fixed duration (Duarte and Freitas 2010;Scoppa et al 2013). The average of two trials in each protocol was calculated and included in analyses.…”

This study introduces the Balance Exercises Circuit (BEC) and examines its effects on muscle strength and power, balance, and functional performance in older women. Thirty-five women aged 60+ (mean age = 69.31, SD = 7.35) were assigned to either a balance exercises group (BG, n = 14) that underwent 50-min sessions twice weekly, of a 12-week BEC program, or a wait-list control group (CG, n = 21). Outcome measures were knee extensor peak torque (PT), rate of force development (RFD), balance, Timed Up & Go (TUG), 30-s chair stand, and 6-min walk tests, assessed at baseline and 12 weeks. Twenty-three participants completed follow-up assessments. Mixed analysis of variance models examined differences in outcomes. The BG displayed improvements in all measures at follow-up and significantly improved compared with CG on, isokinetic PT60, PT180 (p = 0.02), RFD (p < 0.05), balance with eyes closed (p values range .02 to <.01) and TUG (p = 0.03), all with medium effect sizes. No changes in outcome measures were observed in the CG. BEC improved strength, power, balance, and functionality in older women. The BEC warrants further investigation as a fall prevention intervention.

| Background: Cystic fibrosis (CF) is a hereditary condition in which lung disease affects all patients. In addition to pulmonary involvement, the multisystemic components of CF cause significant physical limitations. However, the impact of lung function on balance control in CF has not been studied. Objective: To assess body balance in adults with CF and to test its possible associations with lung function, nutritional status, and functional capacity. Method: This was a cross-sectional study in which 14 adults with CF underwent pulmonary function testing (spirometry, body plethysmography, and carbon monoxide diffusing capacity (DLco), respiratory muscle strength, 6-min walking distance (6MWD), Berg balance scale (BBS), nutritional analysis (body mass index and bioelectrical impedance), and stabilometry. Body balance was quantified using stabilometry; all participants performed the following two trials: opened base, eyes open (OBEO); closed base, eyes closed (CBEC). Results: In stabilometry, the median for the lateral range and anterior-posterior range in the CBEC trial was 0.10 (0.08-0.11) and 0.13 (0.11-0.22), respectively (p<0.05). The maximal inspiratory pressure (MIP) correlated inversely with the lateral standard deviation (ρ=-0.61; p<0.05) as the DLco correlated positively with the anterior-posterior range (ρ=0.54; p<0.05). There were significant relationships between body composition indexes and almost all stabilometric variables measured. There were no relationships of the BBS and 6MWD with the stabilometric variables. Conclusions: In adults with CF, imbalance occurs mainly in the anterior-posterior direction and is especially associated with body composition.Keywords: cystic fibrosis; rehabilitation; respiratory function tests; postural balance; psychomotor performance; nutrition assessment.

“…Thus, one may adduce that such strategies were used to improve body control by increasing the rigidity of the system, which oscillated more slowly and over a larger area, as an attempt to reduce the CoP displacement and the unbalance on the anteroposterior and mediolateral planes. The difficulty associated with controlling the motions that increase system rigidity increases together with fatigue, and this may be associated with the greater oscillations exhibited by the CoP 34 .…”

| Objective:This study sought to analyze the effect of muscle fatigue induced by active isotonic resistance training at a moderate intensity by measuring the knee extension motion during the stabilometric response in a single-leg stance among healthy university students who perform resistance training on a regular basis. Method: Eleven healthy university students were subjected to a one-repetition maximum (1RM) test. In addition, stabilometric assessment was performed before and after the intervention and consisted of a muscle fatiguing protocol, in which knee extension was selected as the fatiguing task. The Shapiro-Wilk test was used to investigate the normality of the data, and the Wilcoxon test was used to compare the stabilometric parameters before and after induction of muscle fatigue, at a significance level of p≤0.05. Descriptive statistics were used in the analysis of the volunteers' age, height, body mass, and body mass index (BMI). Results: The sample population was 23.1±2.7 years of age, averaged 1.79.2±0.07 m in height and 75.6±8.0 Kg in weight, and had a BMI of 23.27±3.71 Kg.m -2 . The volunteers performed exercises 3.36±1.12 days/week and achieved a load of 124.54±22.07 Kg on 1RM and 74.72±13.24 Kg on 60% 1RM. The center of pressure (CoP) oscillation on the mediolateral plane before and after fatigue induction was 2.89±0.89 mm and 4.09±0.59 mm, respectively, while the corresponding values on the anteroposterior plane were 2.5±2.2 mm and 4.09±2.26 mm, respectively. The CoP oscillation amplitude on the anteroposterior and mediolateral planes exhibited a significant difference before and after fatigue induction (p=0.04 and p=0.05, respectively). Conclusions: The present study showed that muscle fatigue affects postural control, particularly with the mediolateral and anteroposterior CoP excursion.Keywords: rehabilitation; muscle fatigue; exercise; postural balance.
