Avaliação da força muscular global e atividades básicas de vida diária de pacientes pós- covid-19 antes e após reabilitação em um hospital de retaguarda / Evaluation of global muscular strength and functionality of patients after-covid-19 before and after rehabilitation in a backup hospital

Abstract Background Numerous studies have demonstrated the efficacy of creatine supplementation for improvements in exercise performance. Few studies, however, have examined the effects of phosphocreatine supplementation on exercise performance. Furthermore, while polyphenols have antioxidant and anti-inflammatory properties, little is known regarding the influence of polyphenol supplementation on muscular strength, power, and endurance. Thus, the purpose of the present study was to compare the effects of 28 days of supplementation with phosphocreatine disodium salts plus blueberry extract (PCDSB), creatine monohydrate (CM), and placebo on measures of muscular strength, power, and endurance. Methods Thirty-three men were randomly assigned to consume either PCDSB, CM, or placebo for 28 days. Peak torque (PT), average power (AP), and percent decline for peak torque (PT%) and average power (AP%) were assessed from a fatigue test consisting of 50 maximal, unilateral, isokinetic leg extensions at 180°·s− 1 before and after the 28 days of supplementation. Individual responses were assessed to examine the proportion of subjects that exceeded a minimal important difference (MID). Results The results demonstrated significant (p < 0.05) improvements in PT for the PCDSB and CM groups from pre- (99.90 ± 22.47 N·m and 99.95 ± 22.50 N·m, respectively) to post-supplementation (119.22 ± 29.87 N·m and 111.97 ± 24.50 N·m, respectively), but no significant (p = 0.112) change for the placebo group. The PCDSB and CM groups also exhibited significant improvements in AP from pre- (140.18 ± 32.08 W and 143.42 ± 33.84 W, respectively) to post-supplementation (170.12 ± 42.68 W and 159.78 ± 31.20 W, respectively), but no significant (p = 0.279) change for the placebo group. A significantly (p < 0.05) greater proportion of subjects in the PCDSB group exceeded the MID for PT compared to the placebo group, but there were no significant (p > 0.05) differences in the proportion of subjects exceeding the MID between the CM and placebo groups or between the CM and PCDSB groups. Conclusions These findings indicated that for the group mean responses, 28 days of supplementation with both PCDSB and CM resulted in increases in PT and AP. The PCDSB, however, may have an advantage over CM when compared to the placebo group for the proportion of individuals that respond favorably to supplementation with meaningful increases in muscular strength.

Creatine supplementation has an ergogenic effect in an acute complex training bout, but the benefits of chronic creatine supplementation during long-term complex training remain unknown. The study aimed to evaluate the effects of 4-week complex training combined with creatine supplementation on sport performances and muscle damage biomarkers. Thirty explosive athletes were assigned to the creatine or placebo group, which consumed 20 g of creatine or carboxymethyl cellulose, respectively, per day for 6 days followed by 2 g of the supplements until the end of the study. After 6 days of supplementation, subjects performed tests of one repetition maximum (1-RM) strength of half squat and complex training bouts to determine the optimal individual post-activation potentiation time. Thereafter, all subjects performed a complex training programme consisting of six sets of 5-RM half squats and plyometric jumps 3 times per week for 4 weeks. Body composition, 30-m sprint and jump performances were assessed before and after the training period. Moreover, blood creatine kinase (CK) activity was analysed at the first and the last training bout. After the training, the 1-RM strength in the creatine group was significantly greater than in the placebo group (p < 0.05). CK activity after the complex training bout in the creatine group was significantly reduced compared with the placebo group (p < 0.05). No differences were noted for other variables. This study concluded that creatine supplementation combined with complex training improved maximal muscular strength and reduced muscle damage during training.

Movement is an inexhaustible means of self realization, self expression and the way of learning about the surrounding world for children with physical and mental disabilities. Due to the lack of general and fine movements child’s coordination might be impaired. Different methods of motor learning increase child’s ability to perform correct movements and enable them in taking care of themselves, in communicating and gaining knowledge. The objective of the research was to determine the influence of physiotherapy on hand movements of the children suffering from cerebral paralysis, Down syndrome and autism. The tasks of the research: 1. To determine the indicators of hand movement functions of children suffering from cerebral paralysis, Down syndrome and autism before and after physiotherapy. 2. To compare the research indicators of hand movement functions of the children suffering from cerebral paralysis, Down syndrome and autism. Twenty seven children diagnosed with cerebral paralysis, Down syndrome and autism participated in the research. Their age was from 10 to 17 years. Mental disability of most of the children was moderate. The children were divided into three groups: the first group consisted of 13 children with cerebral paralysis, the second group – 8 children with Down syndrome, the third group – 6 children with the diagnosis of autism. Before the first physiotherapy activity the children of all three groups had their hand movements, the frequency of hand movements and their speed researched. The second study was performed after the first physiotherapy activity which lasted for two months, three times a week, thirty minutes a day. The third study was performed after the second physiotherapy activity which followed the first one and lasted for two months, three times a week, thirty minutes twice a day. Physiotherapy program consisted of stretching and exercises exercises for strength, movements for fine and gross motorics and a game. The exercises were done individually, making them more intensive step by step. The tepping test was used to measure the speed and the frequency of hand movements. The strength of muscles was measured with the help of a mechanic dynamometer. The results demonstrate that physiotherapy is effective. The functions of hand movements of children suffering from cerebral paralysis, Down syndrome and autism have improved. The frequency and the speed of hand movements, as well as muscular strength have increased (p < 0.05). Having compared the data of all three research groups we can make a conclusion that the kind of physiotherapy employed was more effective for the children with Down syndrome and autism than for those who had cerebral paralysis.Keywords: kinesitherapy, cerebral palsy, Down syndrome, autism.

Lower Body Strength

Strength and conditioning coaches frequently use traditional resistance training (TRT) to build strength. However, in recent years, whole-body electromyostimulation (WB-EMS) was used in elite athletes to increase muscle strength. This study aimed to assess the effect of two different types of training on muscular strength. Sixty female collegiate players (Age = 23.52±1.89 years, Height = 156.20±1.71cm; Mass = 53.21±3.17kg) participated in this study and were randomly assigned to three training groups. All groups trained as usual for eight weeks, except for the first group, which received additional TRT. The second group received additional electrical stimulation training, and the third group did not receive any additional training following the regular softball bat swing training. Muscular strength (upper and lower body) was assessed by a 3RM bench press and a 3RM squat test before and after the eight-week programme. The primary findings indicate that after eight weeks of training, upper body and lower body strength increased significantly in both the TRT and WB-EMS groups (p = 0.000 and p = 0.000, respectively) in comparison to the control group. However, the t value indicated that the TRT group improved both upper body strength (20.18) and lower body strength (29.18) more than the WB-EMS group (upper body = 6.18; lower body = 6.47). The findings demonstrate the efficacy of both training modalities for increasing muscular strength and suggest that TRT be prioritised over whole-body electrical stimulation training for increasing muscular strength in collegiate softball players.

Biomarkers Of Oxidative Stress

Introduction: The characterization of immune and oxidative stress responses to acute and chronic exercise training is important because it may aid in the safety and dose–response prescription of resistance training (RT) in many populations.Purpose: The present study compared changes in acute oxidative stress and markers of apoptosis in immune cells before and after 8 weeks of low-load RT with total or partial blood flow restriction (BFR) versus high-load traditional RT.Methods: Twenty-seven untrained men were randomly divided into three groups: traditional RT [75% one-repetition maximum (1-RM)], RT with partial (20% 1-RM), and total BFR (20% 1-RM). Over an 8-week period, participants performed six sets of arm curls until failure with 90 seconds of recovery for 3 days/week. Blood samples were obtained before and after the first and last training sessions.Results: Data indicated that all training groups showed similar increases in muscular strength (p < 0.001), reduction in mitochondrial membrane potential (MMP) after exercise in neutrophils (p < 0.001), and increase in caspase-3 activity after exercise (p < 0.001). Traditional RT and total BFR showed increased plasma lipid peroxidation (p < 0.001) and protein carbonyls (p < 0.001) and lower levels of reduced glutathione (GSH) (p < 0.001) after exercise. No change was observed in oxidative stress biomarkers in response to partial BFR (p > 0.05).Conclusion: Data show that RT with partial BFR can increase muscular strength but still does not augment biomarkers of oxidative stress in untrained men. In addition, RT with total BFR promoted similar responses of oxidative stress and markers of immune cell apoptosis versus traditional RT.

Background and Study Aim. Resistance training is considered as the most effective method to increase muscle strength and mass. The present study aimed to compare the effect of a double pyramid and a flat pyramid training methods on hypertrophy and muscular strength of male power-lifters. Material and Methods. Thirty students (age 21.40±1.71 years) were randomly assigned to three groups of double pyramid training (10 subjects), flat pyramid training (10 subjects), and the control trained by the traditional method (10 subjects). The experimental groups were trained three sessions a week for eight weeks whereas the control group continued their ordinary training program in the traditional method two sessions a week. Before and after the training, the muscular strength index was measured by bench press, leg press, and deadlift and the muscle volume was determined in their chest, arm, and thigh. Data were statistically examined by the analysis of variance and paired t test in the SPSS (ver. 21) software package. The significance level was set at the P<0.05 level. Results. Significant differences were observed among the studied groups in the variables of bench press, leg press, and deadlift, as well as in the variables of arm volume, chest volume, and thigh volume (P < 0.05). Bench press, leg press, deadlift, and the volume of arm, chest, and thigh were increased significantly from the pretest to the posttest in all three groups (P < 0.001). Conclusion. A double and flat pyramid training period has similar positive impacts on muscular strength and volume of power-lifters.

Purpose: The objective of this study is to observe the efficacy of orofacial myofunctional therapy in children who breathe through their mouths “mouth breathers” using a clinical assessment and surface electromyography. Method: 30 nasal breath (control group) and 30 mouth breathers (study group) were evaluated initially, and the study group was re-evaluated after 12 sessions of orofacial myofunctional therapy. Assessments involved the MBGR protocol and surface electromyography. Results: The control group had significantly better scores on all nasal breathing tests compared to mouth breathers both before and after therapy. However, mouth breathers demonstrated statistically significant improvements over time with therapy. Conclusion: After twelve orofacial myology therapy sessions, the mouth breathers improved but not to normal levels. Inadequate muscular strength remained for the required tasks suggesting that additional therapeutic intervention is needed or that therapeutic success is inhibited by a vertical craniofacial growth pattern.
