The purpose of this study was to investigate the number of repetitions and the MEF of the Biceps brachii for the 3 sets of maximal repetitive barbell curls with 3intensity. The subjects which were selected as men in their 20s who had more than 2 years of resistance exercise experience. The subjects also conducted a bar-cull experiment at each 7-day interval with a randoml assignment (50%1RM, 70%1RM, 90%1RM). In every one of the sets, the number of repetitions and the MEF of the Biceps brachii were measured. The measured two-way ANOVA was used, and the statistical significance was noted at the result of a = .05. The higher the intensity condition, the fewer the number of repetitions performed by the subject. The decrease of the number of repetitions was larger with a lower intensity condition. The lower the intensity, the higher the level of muscle fatigue was noted in the subject. In conclusion, it seems that the maximum repetitive exercise is seen to increase the muscle fatigue as the intensity is lower in those instances. Therefore, it is necessary to write a program considering the degree of muscle fatigue at low intensity in resistance exercise for the best results during an exercise program.

Abstract The scope of this study was to evaluate the anthropometric and metabolic changes after low intensity home-based exercise. In the school year of 2007, 95 school cooks in the city of Niteroi (State of Rio de Janeiro, Brazil) were randomly assigned to one of the following groups: home-based exercise (n = 47) or control group (n = 48). The home-based exercise program was performed three times a week, during 40 minutes at moderate intensity. Anthropometric variables were collected at the baseline and after 4 and 8 months, whereas biochemical and individual food intake were measured at the baseline and after 8 months. Energy expenditure was evaluated only at the baseline. The home-based exercise group exhibited a greater weight loss (-0.9 vs. -0.2; p = 0.05) in comparison with controls during the follow-up and the same pattern was found for BMI (-0.1 vs. +0.1; p = 0.07), although without statistical significance. Exercise showed no effects on waist circumference, lipid profile and glucose. In conclusion, greater weight loss was observed in the group that performed low intensity home-based exercise and this strategy can assist in body weight control even without alterations in terms of lipids and glucose.

Low Intensity Exercise

(1) Background—The application of neuromuscular electrical stimulation (NMES) combined with low-intensity exercise to the elderly can be more efficient than low-intensity exercise only in terms of delaying the loss of muscle mass. We aimed to assess the adjunct of NMES to low-intensity lower limb strengthening exercise to prevent falls in frail elderly for a relatively short period of 4 weeks. (2) Methods—Thirty elderly women aged 65 or above were randomly categorized into three groups: control group (CON, n = 8), exercise group (EX, n = 10), and NMES with exercise group (EX + NMES, n = 9). The exercise group took part in a lower limb strengthening exercise program for one hour three times a week for four weeks. Furthermore, the NMES with exercise group had added NMES stimulation when exercising. The limbs’ muscle mass, body fat mass, calf circumference, grip force, five times sit-to-stand test, timed up-and-go test (TUG), one-leg stand test, and Y-balance test (YBT) were evaluated at baseline and 4 weeks after. (3) Results—Comparisons between the three groups showed that the TUG was significantly decreased and the YB was significantly increased in NMES with exercise group (p < 0.05). (4) Conclusions—These results suggested that a combination of NMES stimulation and exercises was more helpful in strengthening balance than exercises alone in the short term.

The Impact

Seniors are a constantly growing group of people in many societies. It is necessary to develop physiotherapeutic programs to improve their mobility. The aim of this study was to assess the impact of the physiotherapeutic program conducted unstable ground on selected indicators of motor functions of elderly women. Sixty women (60–80 years) participated in the research. Group A (N = 20) underwent a 12-week physiotherapeutic program on stable ground, group B (N = 20) followed an exercise program on unstable ground, and group C (N = 20) (control group) had no therapeutic intervention. The effects of the therapy were assessed by using a FreeMed platform (foot load analysis) and a Biosway balance system. The results were compared using ANOVA (the one-way analysis), the Kruskal–Wallis test and also the post hoc tests (Tukey’s test and the multiple comparison test). In group A, a statistically significant change was observed in the static test and balance assessment, in group B this was observed in the static and dynamic foot tests and balance assessment, in group C, no statistical significance was achieved. The authors’ physiotherapeutic program had a statistically significant effect on changes in the balance and selected indicators of the motor functions of the examined people. Comparing the results before and after the therapy more improvement changes were noted in women training on an unstable ground compared to women training on a stable ground.

ABSTRACTAn ongoing, structured, low-intensity exercise program designed to foster physical, social and cognitive functioning was evaluated in 128 seniors ranging in age from 55 to 101 years. The sample included individuals residing in the general community, seniors' apartment complexes and institutional care facilities. Participation in other exercises was found to increase since joining the program. The program appeared to be providing an opportunity for social interaction among participants, and the exercises appeared to be mentally stimulating. Implications for program modifications, including building in self-monitoring procedures, are discussed.

Twelve male subjects were tested to determine the effects of motor unit (MU) recruitment and firing frequency on the surface electromyogram (EMG) frequency power spectra during sustained maximal voluntary contraction (MVC) and 50% MVC of the biceps brachii muscle. Both the intramuscular MU spikes and surface EMG were recorded simultaneously and analyzed by means of a computer-aided intramuscular spike amplitude-frequency histogram and frequency power spectral analysis, respectively. Results indicated that both mean power frequency (MPF) and amplitude (rmsEMG) of the surface EMG fell significantly (P less than 0.001) together with a progressive reduction in MU spike amplitude and firing frequency during sustained MVC. During 50% MVC there was a significant decline in MPF (P less than 0.001), but this decline was accompanied by a significant increase in rmsEMG (P less than 0.001) and a progressive MU recruitment as evidenced by an increased number of MUs with relatively large spike amplitude. Our data suggest that the surface EMG amplitude could better represent the underlying MU activity during muscle fatigue and the frequency powers spectral shift may or may not reflect changes in MU recruitment and rate-coding patterns.
