Introduction and objectives. Since the paravertebral muscles promote dynamic stability to protect the spine, the aim of this study was to verify the association between the acute effect of the stretching support time for the multifidus muscle, and changes in the static and dynamic stability of the lumbopelvic region. Materials and method. A total of 46 volunteers were cross-submitted to three different stretching interventions for the multifidus muscle, being the manutention of stretching time the variation between interventions: 10, 30 and 60 seconds. Each volunteer was submitted to the three interventions with a minimum interval of 7 days and a maximum of 10 days. The order of the interventions was determined by lot. First, pre-intervention values for static and dynamic stability were collected using a biofeedback pressure unit. Subsequently, the sample was forwarded for intervention according to its group; after the completion of the same, data were collected on post-intervention stability. The data were analyzed using SPSS 20.0 software and Chi-square test, with a significance level of 5% (α = 0.05). Results. There was no significant association between the manutention of stretching time and static stability, being χ2(4)=0.812; p=0.949. Similarly, there was no significant association between the stretching support time and dynamic stability, and χ2(4)=1.517; p=0.827. Conclusion. In conclusion, there was no significant association between stretching time of the paravertebral muscles and static and dynamic stability.

Background. The aim of the study was evaluate the strength of the respiratory muscles, bite force, and occlusal force distribution of professional soccer players after training and detraining resulting from the lockdown that occurred during the coronavirus disease 2019 pandemic. Material and methods. Twelve male soccer players (age, 19-34 years) were subjected to respiratory muscle strength analysis by examining the maximal inspiratory and expiratory pressures, maximum molar bite force (right and left sides), and occlusal force distribution of the first permanent molars. Comparisons of variables after training and detraining were analyzed using the paired-sample t-test (p < 0.05), and the correlation between respiratory variables was measured using the Pearson test (p < 0.05). Results. There were no significant differences in the bite force and occlusal force distributions after training and detraining. The correlation results showed moderate positivity between the maximal inspiratory and expiratory pressures during the training period. Conclusions. The results suggest that when soccer players strengthen the inspiratory muscles, they also strengthen the expiratory muscles and that detraining does not impact the athlete's organic function, especially the respiratory muscle function and the forces of the occlusal contact of the first permanent molars.

Introduction. Muscle strengthening to improve joint stability is widely used in the rehabilitation process, and the use of neuromuscular electrical stimulation is a useful tool, but the use of Aussie current still has little documentation about its effectiveness. Aim. To verify if there is a dose-response effect to Aussie current, both in the strength and in the static and dynamic stability of the deep pelvic lumbar muscles. Material and methods. 39 volunteers divided into four groups, one control and three electrostimulation with intensity variation, one with intensity at the contraction threshold (GT), another with intensity maintained at 20% more (G20), and another with intensity maintained at 30% more (G30) than the intensity at the contraction threshold. The intervention lasted four weeks, with three weekly sessions lasting 15 minutes. Initially and after the intervention period, the strength and stability of the deep muscles of the pelvic lumbar region were measured in a static and dynamic manner by a biofeedback pressure unit. Results. There was a significant increase of pressure under the lordoses in the pre- and post-evaluation moments, there were no differences in the evaluation of indirect force (dynamic stability), but there was an increase in the time for GT. The effect sizes presented advantages for the electrostimulated groups in static stability. Conclusion. The doses used did not promote significant statistical differences, but the effects were positive for the electrostimulated groups, especially with respect to static stability.

Introduction: Osteogenesis imperfecta (OI) is a genetic disorder of increased bone fragility and low bone mass. OI type IV. Materials and methods: We examined the safety and effectiveness of a low dose of analog granulocyte colony-stimulating factor (G-CSF) in a 15-year-old girl OI type IV. G-CSF 5 μg/kg was given subcutaneously, for 5 days/month for 3, 6 and 12 months. Laboratory tests, including blood, biochemical tests were performed, in addition to clinical examination.Results: Clinical examination revealed an increase of muscle strength in the upper and lower limbs between base line and day 6 and 12 months. We found no serious adverse events. Leukocyte levels remained below 38,000/μL. Low dose G-CSF was safe and well tolerated by the patient. Conclusions: A significant increase in muscle strength in this patient may indicate beneficial effects of G-CSF factor in this disorder. These results are inspiring and warrant further studies.

Opis:
Spasticity is one of the main causes of contracture, muscle weakness and subsequent functional incapacity. The passive static stretching can be included as having the purpose of increasing musculoskeletal flexibility, however, it also can influence the muscle torque. The objective is to verify the immediate effect of passive static stretching in the muscle strength of healthy and those who present spastic hemiparesis. There were assessed 20 subjects, 10 spastic hemiparetic (EG) and 10 healthy individuals (CG), including both sexes, aged between 22 and 78 years. The torque of extensor muscles of the knee was analyzed using isokinetic dynamometer. Results have shown that EG has less muscle torque compared to CG ( p < 0.01). In addition, EG presented a decrease in significance of muscle torque after stretching ( p < 0.05), however, it has not shown significant alteration in muscle torque of CG after performing the program that was prescribed. Immediately after the passive stretch, a significant torque decrease can be seen in hypertonic muscle; it is believed that this reduction may be associated with the physiological overlap between actin and myosin filaments and so preventing the muscle to develop a maximum contraction.

We examined the safety and effectiveness of a low dose of analog granulocyte-colony stimulating factor in a 15-year-old boy with facioscapulohumeral dystrophy. The onset of disease was noted at 12 years of age. The physical examination noted general muscle atrophy more pronounced at left side of the body. He was able to walk 300 meters within 6 minute walk test. Granulocyte colony-stimulating factor 5 μg/kg was given subcutaneously daily for 5 days/month for 1, 2, 3, 6 and 12 months. Clinical examination, laboratory tests including blood, biochemical tests, and CD34+ cells were performed. A significant increase of muscle strength in the lower and upper limbs between baseline, and after 3 months of treatment, after 6, and after 12 months was found. He was able to walk 480 meters within 6 minutes after 12 months. Electromyography demonstrated increase of amplitude in the examined in upper and lower limbs after six months compared to baseline. Leukocyte levels remained below 25000/μL. CD34+ increased significantly at day 5 of granulocyte colony-stimulating factor admini-stration. It was safe and well tolerated by the patient. A significant increase in muscle strength in this patient with facioscapulohumeral dystrophy after 3 months of treatment, after 6, and after 12 months since the first treatment course was completed may indicate beneficial effects of granulocyte colony-stimulating factor in this disorder.

Opis:
Purpose: The assessment of hip joint abductor muscle strength is most often carried out using a dynamometric test. However, both in clinical practice and literature, evaluation is performed by means of the single-leg half-squat or the amount of abduction movements performed in the hip joint. In this context, the question arises whether the results of individual tests are convergent. The aim of the study is to evaluate the relationship between strength of the hip abductor muscle measured by dynamometer, the single-leg-squat and the number of repetitions of the movements in time. Methods: A group of 35 students (20 women and 15 men) between 20 and 24 years old participated in the study. Each student was subjected to three tests assessing the condition of the hip and associated abductor muscles. Those included: assessment of hip joint abduction muscle strength in a dynamometric study, assessment of the number of abdomen movements performed lying on the side and standing, during a 30-second interval, and the single-leg-squat test. Results: Based on the tests conducted, a significant relationship was observed between the muscle strength measurement results for the left and right side in the dynamometric study and the number of hip abduction repetitions in 30 seconds and the single-leg-squat test. Conclusions: The obtained results indicate a significant relationship between the results of all the tests. In practice, this means that the tests can be used interchangeably.

The low achievement of long jump athletes and the limited virtual-based aquatic plyometric exercises to increase lower extremity muscle strength are the gaps in this study. This study aims to increase lower extremity muscle strength of long jump athletes through virtual-based plyometric aquatic training. This research adopted a mixed methods research. This study involved participants from long jump athletes at the University of Tanjung Pura in Indonesia (n = 20). Participants were divided into two groups, namely an experimental group (n = 10) and control group (n = 10). The quantitative instrument involved a leg dynamometer for measuring lower extremity muscle strength. While, the qualitative instrument used in-depth interview. Quantitative data analysis was carried out through IBM SPSS to calculate descriptive statistics and normality, while the paired sample t-test to test differences in lower extremity muscle strength values in the experimental and control groups. Qualitative analysis was carried out through recording, describing and coding stages, which categorized into three themes. Based on quantitative results, it showed that virtual-based plyometric aquatic training was proven significantly increase lower extremity muscle strength (ps0.05), but there was no significant effect in the control group (p & 0.05). Qualitative results found out that most of the participants gave a positive opinion regarding virtual-based plyometric aquatics. Thus, this study confirms that virtual-based plyometric aquatic training can be used to increase lower extremity muscle strength.

Purpose: The aim of this study was to determine the muscles with the lowest strength in nonaffected (non-A) and affected upper limb (A), to assess differences between men and women and to correlate these values with age in patients after stroke. Methods: Sixty hospitalized in Neurorehabilitation Ward patients (40 male, 20 female), 1-2 weeks after stroke, were enrolled to the study. Their age ranged from 50 to 80 years with a mean (sd) of 65,5 (18,7) years. Muscle force values from upper limb muscles were measured using the MicroFet 2 hand-held dynamometer. The results are displayed in newtons [N], mean values of muscular force, effect sizes and confidence intervals displayed as Cohen’s d and 95% CI were determined. Moreover, we made the coefficients correlation for differences in muscular force versus the Rivermead Motor Assessment (RMA) arm section. Results: Strength of (A) upper limb in comparison to (non-A) was 39% weaker. The severely affected muscle groups were the shoulder flexion 41% (women) versus 46% (men); elbow flexion 39% (women) versus 31% (men); wrist extension 36% (women) versus 42% (men). No significant correlations were found between muscle strength results and RMA or age. Conclusions: Muscle force of (A) upper limb after stroke demonstrates 39% decrease. Men show more significant decrease than women (40% vs 35%). Functional assessment in RMA values show the better results in women (4,9 ± 4,1) than men (3,4 ± 3,2).

The anterior cruciate ligament (ACL) tear is a common injury in basketball. Its consequence is a long absence from training, resulting from surgical treatment and long physiotherapy. The aim of the study was to assess muscle strength, postural stability and functional movements in female basketball players, who returned to professional sport careers after anterior cruciate ligament reconstruction. Methods: The study population consisted of 10 female basketball players after surgical reconstruction of anterior cruciate ligament. The control group consisted of 10 players without ACL injury. We used the Biodex System 4 Pro dynamometer to assess the muscle strength of the knee. We used it to conduct the test of flexors and extensors of the knee in isokinetic conditions. We also used Keiser Power Squat A300 in the single leg squat to measure power and the Biodex Balance SD dynamographic platform to assess balance in single leg stance. Results: We found deficits in both movement patterns and in muscle strength in the study population, compared to control group. Conclusions: The basketball players after ACL reconstruction had significant differences between the operated and non-operated limb. The differences may predispose them towards repeated ACL injuries.

Background: Evaluation of body posture and strength of spinal muscles in children during their progressive ontogenesis is significant for the evaluation of their physical health condition and physical fitness. It is also a reference point in a process of control and medical care. Purpose: The aim if this study was to evaluate correlation between the selected features of somatic body structure, shape of anteroposterior spinal curves and force-velocity (FV) parameters of trunk muscles in school children. Participants and methods: The sample involved 104 children aged 10–11 years, 60 females (10.74 ± 0.7) and 44 males (10.50 ± 0.9). Body posture was assessed using the Moiré photogrammetry while trunk muscles (flexors and extensors) strength was measured isokinetically. Results: The results of the research revealed the existence of many average and strong correlations observed between the analysed somatic characteristics and forcevelocity (FV) parameters of trunk muscles. Correlation between the volume of the spinal curvatures in the sagittal plane and forcevelocity parameters of trunk extensors and flexors were average or weak for both groups of children. Conclusion: Somatic features indicated stronger correlation with trunk muscles' strength than with the size of the anteroposterior spinal curves.

These aim of the study was to conduct a long-term evaluation of whether total hip replacement permanently affects the dynamic body balance. Methods: Twenty-five patients after the unilateral total hip replacement (mean age: 69.9 ± 6.2) and 25 subjects without the total hip replacement (mean age: 68.4 ± 4.8) who matched the age and overall health participated in this study. The force platform and functional tests such as Timed Up and Go, 3m walk test, Functional Reach Test, 30s Chair Stand Test, Step Test and Berg Balance Scale were used to assess dynamic balance. The results obtained in individual trials were compared using the Student’s t-test for independent variables, the Welch test or the non-parametric Mann–Whitney U-test. Results: Subjects from the THR group exhibited significantly increased time and distance in the tests performed on the force platform, compared to the control group. We also observed worse balance and functional test scores in the THR group: Timed Up and Go test ( p < 0.001), 3 m walk test ( p < 0.001), Functional Reach Test ( p < 0.001), 30 s Chair Stand Test ( p = 0.001) and Step Test (operated leg: p < 0.001, non-operated leg: p < 0.001). The results obtained in the Berg Balance Scale tests were not significantly different between the groups ( p = 0.218). Conclusions: We observed significant differences in postural stability and dynamic balance between patients after THR and subjects in the same age without endoprosthesis. Our research shows that total hip replacement permanently impairs patients’ dynamic balance and their functionality in certain lower-extremity activities.

Opis:
Unplanned gait termination (UGT) widely occurs in various sports and daily life as a kind of stress response to unexpected stimulus. However, the body stability may be greatly affected when the body completely stops. The purpose of this study was to examine the association between muscle strength levels and body stability during UGT through comparing the plantar pressure. Methods: Twenty healthy participants (10 male and 10 female) with different lower limbs muscle strength and power were asked to perform planned gait termination (PGT) and unplanned gait termination (UGT) on an 8-m walkway. Related plantar pressure data including maximum pressure, maximum force, contact area and center of pressure were recorded with Footscan pressure platform. Results: Two types of gait termination have significant differences in the plantar pressure distribution. Maximum pressure and maximum force in the lateral metatarsal increased significantly during UGT, compared to PGT. At the same time, data from the current study suggested that there might be a correlation between the muscle strength levels of individual and the stability during the gait termination, especially between the muscle power and UGT, which means that the more excellent muscle power an individual has, the more stable the body is when UGT is performed. Conclusions: The findings suggest that different muscle strength levels could affect stability during unplanned gait termination.

Opis:
Introduction: In this study, strength and endurance of the trunk muscles were assessed in patients with spondyloarthrosis of the lower spine. Material and methods: 52 women and 49 men with low back pain syndrome (LBPS) were enrolled into the study. The muscle strength of the flexors and extensors of the trunk was determined by calculation of the maximum (MT) and relative torque (RT) during an isometric contraction. Evaluation of endurance of the extensors used calculation of the regression coefficient of the strength reduction during the testing of maximum strength capability. The obtained results were compared to results obtained in healthy persons. Moreover, the relation of those parameters to age, body-mass index – BMI (describing somatic habitus) and the Oswestry Disability Index – ODI (describing pain intensity during activities of daily living) was assessed. Separate analyses were conducted for the groups of males and females.Results: Based on the conducted study and the performed analyses, it can be stated that in patients with chronic low back pain syndrome there is a marked reduction in trunk muscle strength as compared to healthy persons. For females, the reduction ranged from 45% (flexors) to 48% (extensors) for absolute maximum torque values, while for relative values (RT) – from 51% (flexors) to 56% (extensors). In men, the strength reduction of abdominal and back muscles was smaller and was approximately 40% (for MT and RT). Because of such differences in the strength of the back muscles and methodological reasons, endurance variables were not compared. Reduction in trunk muscle strength is primarily due to the pain syndrome and does not depend on patients’ age or habitus. Lower muscle strength can affect the intensity of spinal pain during every-day activities.Conclusions: Precise determination of strength and endurance of the trunk muscles and the appropriate selection of methods of their reinforcement should constitute one of the principal aims of rehabilitation treatment in patients with low back pain.

Opis:
Prawidłowe stężenie testosteronu, odpowiednia kompozycja składu ciała i siła mięśniowa w wielu dyscyplinach odgrywają znaczącą rolę w procesie optymalizacji formy sportowej. Osoby charakteryzujące się niedoborem witaminy D mają wyższe ryzyko występowania hipogonadyzmu. Suplementacja witaminy D przy niskich, wyjściowych stężeniach testosteronu może zwiększyć stężenie testosteronu u mężczyzn. Z uwagi na lipofilność witaminy D, nadmiernie rozwinięta tkanka tłuszczowa zwiększa ryzyko niedoborów witaminy D poprzez wiązanie jej w adipocytach. Sportowcy o wyższym wskaźniku BMI (ang. Body Mass Index – wskaźnik masy ciała), nawet mieszczącym się w granicach normy (18,5-24,9 kg/m2) mogą wymagać wyższych dawek suplementacyjnych witaminy D. Odkrycie VDR (ang. Vitamin D Receptor – receptor witaminy D) w obrębie tkanki mięśniowej dało podstawy by sądzić, że witamina D ma wpływ na siłę mięśniową. Stężenie 25 (OH) D jest dodatnio skorelowane z siłą mięśniową. Suplementacja witaminy D3 zwiększa siłę mięśniową od 1,37% do 18,75%. Suplementacja witaminy D2 nie zwiększa siły mięśniowej. Istnieje ograniczona liczba publikacji naukowych traktujących o wpływie witaminy D na stężenie testosteronu, kompozycji sylwetki i siłę mięśniową, jednak przeprowadzone badania jednoznacznie wskazują na korzyści wynikające z odpowiedniego odżywienia witaminą D. Optymalne stężenie w surowicy krwi 25 (OH) D wynosi 30-50 ng/ml. W okresie od września do kwietnia zalecana jest suplementacja dla ogółu społeczeństwa w dawce 800-2000 UI witaminy D3 dziennie.
The testosterone concentration, body composition and muscular strength in play a significant role in the process of optimizing the sports form. People with vitamin D deficiency have a higher risk of hypogonadism. Vitamin D supplementation at low initial testosterone levels can increase testosterone levels in men. Due to lipophilicity of vitamin D, excessively developed adipose tissue increases the risk of vitamin D deficiency by binding it in adipocytes. Athletes with a higher BMI (Body Mass Index), even within the normal range (18.5-24.9 kg / m2) may require higher doses of vitamin D supplementation. The discovery of VDR (Vitamin D The receptor – the vitamin D receptor) within the muscle tissue gave grounds to believe that vitamin D has an effect on muscle strength. Concentration 25 (OH) D is positively correlated with muscular strength. Vitamin D3 supplementation increases muscle strength from 1.37% to 18.75%. Vitamin D2 supplementation does not increase muscle strength. There are a limited number of scientific publications regarding the influence of vitamin D on testosterone concentration, silhouette composition and muscular strength, however, conducted research clearly indicate the benefits of adequate nutrition with vitamin D. Optimal blood serum concentration 25 (OH) D is 30-50 ng / ml. In the period from September to April, supplementation is recommended for the general public at a dose of 800-2000 UI of vitamin D3 per day.
