This investigation examined alterations in neuromuscular drive for dynamic and static muscle contractions, muscle strength, and cross-sectional area (CSA) with a 12-week progressive resistance-training program (PRT). Nine healthy men (70.0 ± 1.7 years) were evaluated for maximal and submaximal neuromuscular drive (integrated electromyography [IEMG]), whole-muscle strength, isokinetic power, and thigh CSA. The results demonstrated no significant differences pre- to post-PRT in the submaximal IEMG signals (p > .05). IEMG increased (p < .05) for the maximal static contraction (29% ± 12%) and isokinetic velocities concentrically and eccentrically. There was an increase (p < .05) in maximal static strength (27% ± 5%), isokinetic concentric and eccentric strength, muscle power, IRM (47% ± 6%), and CSA (6% ± 1%; p < .05). The results reveal significant neuromuscular-drive alterations in concentric and eccentric dynamic contractions with PRT in older men and indicate that their neuromuscular drive contributes significantly to improving their concentric and eccentric skeletal-muscle strength.

10027 Background: Muscle weakness, low lean muscle mass and poor physical performance are prevalent among adult survivors of childhood cancer. We evaluated the effects of resistance training with and without protein supplementation on lean muscle mass, and muscle strength among childhood cancer survivors. Methods: This double-blind placebo-controlled trial enrolled survivors aged ≥18 to < 45 years. Participants were randomized to resistance training with daily protein supplement (21g protein/day, 90kcal) (RT+S) or resistance training with placebo (sucrose, 90kcal) (RT+P). Both groups received educational materials, access to a local fitness center and a tailored resistance training program with tapered supervision. Lean muscle mass and muscle strength were assessed at baseline and 24 weeks, using dual x-ray absorptiometry and dynamometer testing respectively. Mean changes were compared within and between groups. Results: Of 93 participants randomized, 57 completed the 24-week intervention (24 in RT+S, 33 in RT+P). The mean age was 33.1 (SD 7.0), 67% were white and 47% female. The RT+S group had a significant increase in lean body mass (1.05 kg [SD 2.34], p = 0.04), while the RT+P group did not (0.13 kg [SD 2.19], p = 0.74). Mean change in handgrip strength also improved in the RT+S group (1.98 [SD 4.30], p = 0.03); change approached significance in the RT+P group (1.49 [SD 4.60], p = 0.07). All survivors significantly improved their strength over time (Table) as measured by one max repetition test at baseline and follow-up. Conclusions: Preliminary findings indicate that a supervised resistance training program among adult survivors of childhood cancer that includes protein supplementation is feasible and may increase total lean body mass and muscle strength.

Background. The aim of this study was to evaluate the effect of a six-month home-based resistance-training program on muscle health and physical performance in healthy older subjects during the unique condition of home confinement caused by the COVID-19 pandemic. Methods. This was a randomized-controlled study that enrolled older participants that were allocated to either an experimental group performing the six-months exercise prescription (EXE) or a control group (CON). At the beginning (PRE), and after 6 months (POST), participants were assessed for muscle strength, balance, gait assessment and body composition by dual energy X-ray absorptiometry and magnetic resonance imaging. Normality distribution of data was checked with the D’Agostino and Pearson test and changes between PRE and POST were assessed by paired Student’s t-test while percentage and absolute changes between groups at POST were tested by unpaired t-test. Results. Nine participants were included for the final analysis: EXE, n = 5 (age: 66 ± 4; BMI: 27.5 ± 3.7) and CON, n = 4 (age: 71 ± 9; BMI: 24.2 ± 4.1). Significant PRE-to-POST changes were observed in the EXE group only in the chair-stand test (+19.8%, p = 0.048 and ES:1.0, moderate) and in total fat mass (+5.0%, p = 0.035 and ES:1.4, large) with no between-group differences. Moreover, EXE had significantly higher absolute thigh CSA values than CON at POST (14.138 ± 2977 vs. 9039 ± 1015, p = 0.0178, ES = 1.7). No other within- and between-group differences were detected. Conclusions. The home-based resistance-training program during the lockdown period, caused by the COVID-19 outbreak, determined only within-group improvement in lower limb muscle strength but not in muscle mass and composition in older subjects. Home confinement may partially explain the increase in total body fat due to a reduced daily PA regime and altered diet pattern.

Leg Press

O treinamento da força (TF) tem se revelado eficaz em idosos frágeis. Contudo, dúvidas persistem sobre a resposta ao treinamento em idosos com nível de independência funcional elevado. O objetivo do estudo foi observar os efeitos de 12 semanas de TF sobre a força muscular em mulheres idosas funcionalmente autônomas, mas sem experiência prévia com este tipo de treinamento. Trinta e cinco mulheres com 62 a 77 anos de idade passaram por anamnese e teste de esforço com ECG. Uma voluntária foi excluída por utilizar marcapasso, outras duas exibiram sinais de isquemia, seis não compareceram ao teste de esforço e sete abandonaram o TF por razões .diversas. A casuística contou com 19 indivíduos (idade = 69 ± 5 anos). Foram realizadas, duas vezes por semana durante 12 semanas, duas séries de 10 repetições máximas (RM) em exercícios para membros inferiores (“leg-press”) e superiores (supino reto). As médias semanais do volume de treinamento foram comparadas através de ANOVA para medidas repetidas (p < 0,05). Os resultados indicaram tendência à melhoria da força durante o período observado, nos dois exercícios, da ordem de 58% para o “leg-press” e 61% para o supino. O ganho de força evoluiu rapidamente nas primeiras quatro semanas, tendendo a estabilizar-se nas semanas finais. Conclui-se que o TF pode apresentar resultados positivos em idosas com bom nível de independência funcional. A possibilidade destes ganhos ocorrerem em treinamentos de prazo mais longo, todavia, revela-se duvidosa

AbstractThe main purpose of this study was to compare the effects on strength and muscle power of a training program based on two different modalities of whole-body electrostimulation (WB-EMS) with respect to a resistance-training program aimed at improving dynamic strength. Twenty-two subjects participated in this study: Thirteen male (age 25.2±2.8 years; height 1.78±0.1 m; body mass 72.8±6.4 kg; body fat 11.6±2.3%) and nine female (age 28.2±3.5 years; height 1.63±0.05 m; body mass 56.8±7.6 kg; body fat 19.1±4.7%). Participants were randomly assigned to three groups that underwent three different 6-week training programs: two modalities of WB-EMS, based on different electrical parameters (experimental), and circuit training with overloads (control). Force-velocity curves were calculated for each participant before and after treatment. All groups improved their level of strength and muscle power (paired sample t-Test, p<0.01; d>1) with a similar magnitude. No significant differences were observed between groups (two-way 2×3 Anova, p>0.05) at the end of the experimentation. This study suggests that WB-EMS might be considered as a valid and faster alternative – or an important complementary procedure – to a traditional overload-based resistance-training program for the development of the DS.

Abstract Objective The aim of the study was to examine the variability in plantar-flexor muscle strength changes after progressive resistance training for adolescents with cerebral palsy (CP) and to identify baseline variables associated with change in muscle strength. Methods Thirty-three adolescents with CP were randomized to a 10-week progressive resistance training program as part of a randomized controlled trial (STAR trial). The associations between muscle strength at 10 weeks (n = 30 adolescents) and 22 weeks (n = 28 adolescents) and biomechanical and neuromuscular baseline characteristics, motor function, and fidelity to the program were examined with multivariable linear regression. Conclusion Assessing levels of muscle activation may be able to identify responders to a progressive resistance training program for adolescents with CP. These findings are a first step toward developing tools that can inform decision making in the clinical setting. Impact Due to the heterogenous nature of CP, it is challenging to assess the efficacy of strength training programs in individuals with CP and to understand the variability in outcomes among participants. This study provides a better understanding of the factors that predict response to an exercise program so that resistance training can be directed to those who will potentially benefit from it. Lay Summary There is wide variability in how well young people with CP respond to resistance training. If you are a young person with CP, your physical therapist can measure the amount of your gastrocnemius muscle activity to get an indication of how well you will respond.
