The study objective is to determine the influence of the combined method of strength development on the dynamics of training effect in girls aged 9 years. Materials and methods. The study involved 15 girls aged 9. The experiment was conducted according to the plan shown in Table 1. The study implemented the first variant of the combined method for developing arm and shoulder muscles (place I), abdominal muscle strength (place II), back muscle strength (place III), and leg muscle strength (place IV). The study materials were processed by the statistical analysis software – IBM SPSS 22. Discriminant analysis was performed. Results. The discriminant analysis indicates statistically significant changes in the training effect of strength exercises (places І–ІV, р < 0.001). The immediate and delayed training effect of strength exercises depends on the total amount of strength exercises in a physical education lesson. Thus, changes after training at each place of strength development are amplified by the subsequent exercises at other places, the differences between the testing indicators are statistically significant (p = 0.001). Conclusion. The study determined a positive training effect of strength exercises when using the combined method of strength development in the following modes: dynamic effort method – 3 repetitions, 30-s rest; maximum effort method – 1 repetition, 30-s rest; isometric effort method – 3 repetitions, 30-s rest; repeated effort method – 6 repetitions, 30-s rest. In strength load response, there are an immediate and delayed training effects. Thus it can be argued that it is possible to classify training effects by the presented battery of tests based on discriminant analysis.

The Impact

The study purpose was to determine the dynamics of training effects of orthogonal modes of strength training in boys aged 8 years. Materials and methods. The study participants were 48 boys aged 8 years. The experiment was performed using a 22 factorial design. The study materials were processed using the IBM SPSS 22 statistical analysis program.Discriminant analysis was performed. The study examined the impact of four variants of strength training loads on the immediate (ITE) and delayed (DTE) training effects of orthogonal modes of strength exercises and rest intervals in 8-year-old boys. Results. In the first variant of strength training, the largest contribution to the dynamics of training effects is made by the work performed at the first place “exercises to strengthen arm and shoulder muscles”; in the second variant, the largest contribution to the dynamics of training effects is made by the work performed at the third place “exercises to strengthen back muscles”; in the third variant, the largest contribution to the dynamics of training effects is made by the work performed at the first “exercises to strengthen arm and shoulder muscles” and the third “exercises to strengthen back muscles” places; in the fourth variant, the largest contribution to the dynamics of ITE is made by thework performed at the first “exercises to strengthen arm and shoulder muscles” and the third “exercises to strengthen back muscles” places. The most significant changes in the DTE are associated with the fourth place’s work “exercises to strengthen leg muscles”. Conclusions. The response to strength training load includes immediate and delayed training effects. Thus it can be argued that training effects can be classified using the given battery of tests based on discriminant analysis. The efficiency of discriminant analysis increases when using 2k FFE active experiments.

The Impact

Background and Study Aim. The purpose of the study was to determine the peculiarities of using pattern recognition method in the management of the cumulative effect of strength loads in 8-year-old boys. Materials and methods. The study participants were 48 boys aged 8. The experiment was conducted using a 22 factorial design. The study materials were processed by the IBM SPSS 22 statistical analysis program. Discriminant analysis was performed. The study examined the impact of four variants of strength load on the formation of the cumulative training effect of three, six, nine, and twelve classes in 8-year-old boys. Results. The discriminant analysis provided information about the impact of four orthogonal variants of strength loads on the formation of the cumulative training effect of strength exercises of three, six, nine, and twelve classes in 8-year-old boys. The obtained data make it possible to choose a load mode at each step of the CTE formation and to manage schoolchildren’s strength training. Conclusions. The verification of the obtained discriminant functions shows their high discriminative ability and value in interpretation with respect to the general population (p < 0.05). It was found that the formation of the CTE of three classes is most influenced by the third load variant, six classes – by the third load variant, nine classes – the third load variant, twelve classes – the first load variant. The discriminant function structure coefficients made it possible to identify the factor structure of the CTE of 3, 6, 9, 12 classes, to find that the CTE3, CTE6 are associated with the work at the first place “Exercises to strengthen arm muscles”, the CTE9, CTE12 – with the work at the third (“Exercises to strengthen back muscles”) and the fourth (“Exercises to strengthen leg muscles”) places. The CTE of three, six, nine, and twelve classes depends on the modes of strength exercises and has different focuses. The CTE3 – speed and strength focus; CTE6, 9 – comprehensive focus; CTE12 – explosive-strength focus. The obtained values of centroids for the CTE of 3, 6, 9, 12 classes enable the management of schoolchildren’s strength training.

Muscle Functions

This study aims to compare muscle functions and functional performances between older persons with and without low back pain (LBP) and to determine the association between muscle functions and functional performances. This is a cross-sectional study, involving 95 older persons (age =70.27±7.26years). Anthropometric characteristics, muscle functions, and functional performances were measured. Data were analyzed using ANOVA, Pearson’s correlation, and multiple linear regression. The functional performances showed no significant differences (females LBP versus non-LBP, males LBP versus non-LBP) (p<0.05). For muscle functions, significant differences were found (females LBP versus non-LBP) for abdominal muscle strength (p=0.006) and back muscle strength (p=0.07). In the LBP group, significant correlations were found between back and abdominal muscle strength and hand grip strength (r=0.377andr=0.396, resp.), multifidus control and lower limb function (r=0.363) in females, and back muscle strength and lower limb function (r=0.393) in males (allp<0.05). Regression analysis showed that abdominal and back muscle strengths were significant predictors of hand grip strength (p=0.041andp=0.049, resp.), and multifidus control was a significant predictor of lower limb function in females (p=0.047). This study demonstrates that older women with LBP exhibit poorer muscle functions compared to older women without LBP.

Older Men And Women

Various factors significantly affect the risk of falls among older adults with lumbar spondylosis. However, the relationship between falls and trunk muscle strength in older men is poorly explored. Thus, we aimed to investigate the relationship between back muscle strength and fall risk in older men and women with lumbar spondylosis. Based on self-reported fall scores, 39 outpatients were classified into two groups. Back and abdominal muscle strength, among other data, were compared between the two groups. Spearman’s rank correlation analysis was used to assess the relationship between fall scores and selected variables. Back (r = −0.491, p = 0.002) and abdominal muscle strength (r = −0.415, p = 0.009) were related to the fall score. Furthermore, back and abdominal muscle strength were related to the fall score in women with a high risk of falls, whereas back muscle strength, erector spinae, and lumbar multifidus cross-sectional areas, and visual analog scale were related to the fall score in men with a high risk of falling. Back muscle strength and fall scores may be useful to assess the risk of falls in older patients with lumbar spondylosis. However, evaluating this relationship may require separate sex-specific analyses.

The increasing number of elderly and elderly life expectancy is a challenge for health workers. Decreased cardiac endurance, muscle strength and increased incidence of inflammation will occur in the elderly as we get older. health cardio exercises series-I is an aerobic exercise that has moderate intensity and is carried out for 30 minutes, research is needed to analyze the effect on cardiac endurance, muscle strength and decrease plasma TNF-? levels in the elderly. Research design with experimental method, pre-test and post-test design approach. The study was conducted for 4 weeks on 25 samples which were divided into 3 groups of frequency of health cardio exercises series-I to measure endurance of the heart. A 6-minute road test and muscle strength were used for hand grip strength dynamometer, test back and leg dynamometer. Measurement of plasma TNF-? levels is carried out using the Elisa method. The data was then analyzed using paired t-test to see differences before and after health cardio exercises series-I. The results showed health cardio exercises series-I performed 3x / mg can increase the heart's endurance compared to the frequency of 4x / mg and 5x / mg (-16.11 vs 15.62 vs -47.62 meters). health cardio exercises series-I frequency of 3x / mg and 4x / mg can increase back muscle strength (p-value = 0.019, p <0.05) and the frequency of 5x / mg can increase the strength of attractive shoulder muscles. (p-value = 0.033, p <0.05). Health cardio exercises series-I performed 3x / mg, 4x / mg and 5x / mg did not have a significant effect on plasma TNF-? protein expression in the elderly (0.506 vs 0.856 vs. 0.382, p <0.05). It is suggested that the elderly can do I-1 series heart exercise with a frequency of 3x / mg to increase the heart's lung endurance and back muscle strength, a health cardio exercises series-I 4x / mg series to increase muscle strength of the back back, a series of health cardio exercises series-I frequency of 5x / mg to increase attractive shoulder muscle strength.

Background. The effect of using robots to improve motor recovery has received increased attention, even though the most effective protocol remains a topic of study. Objective . The objective was to compare the training effects of treatments on the wrist joint of subjects with chronic stroke with an interactive rehabilitation robot and a robot with continuous passive motion. Methods. This study was a single-blinded randomized controlled trial with a 3-month follow-up. Twenty-seven hemiplegic subjects with chronic stroke were randomly assigned to receive 20-session wrist training with a continuous electromyography (EMG)-driven robot (interactive group, n = 15) and a passive motion device (passive group, n = 12), completed within 7 consecutive weeks. Training effects were evaluated with clinical scores by pretraining and posttraining tests (Fugl-Meyer Assessment [FMA] and Modified Ashworth Score [MAS]) and with session-by-session EMG parameters (EMG activation level and co-contraction index). Results. Significant improvements in FMA scores (shoulder/elbow and wrist/hand) were found in the interactive group ( P < .05). Significant decreases in the MAS were observed in the wrist and elbow joints for the interactive group and in the wrist joint for the passive group ( P < .05). These MAS changes were associated with the decrease in EMG activation level of the flexor carpi radialis and the biceps brachii for the interactive group ( P < .05). The muscle coordination on wrist and elbow joints was improved in the interactive groups in the EMG co-contraction indexes across the training sessions ( P < .05). Conclusions. The interactive treatment improved muscle coordination and reduced spasticity after the training for both the wrist and elbow joints, which persisted for 3 months. The passive mode training mainly reduced the spasticity in the wrist flexor.
