A Study to Assess the Effectiveness of TAI CHI Ch-Uan Exercises on Balance Control among Older People Living in Selected Old Age Homes in Bangalore, Karnataka

Background and Purpose: The treatment of balance disorders lacks a fixed method, with identification andmanagement of external factors being crucial. Many balance disorders benefit from balance training and moderatephysical activity. Exercise programs encompass strength training, balance and coordination exercises, dual tasktraining, hydrotherapy, tai chi, and yoga, all proven to enhance balance. Tai Chi Chuan, a martial art, utilizes slow,graceful moves and precise body movements to enhance body awareness and balance, combined with breathingtechniques for mind-body harmony and energy flow. Practicing Tai Chi fosters muscle strength, flexibility, aerobicconditioning, and stress reduction, contributing to overall well-being and balance improvement.Methods: The study was conducted at Omashram Trust, Bangalore, Karnataka. The research design selectedfor the study was quasi experimental pre-test post-test with experimental and control group. Non probabilitypurposive sampling technique was adopted to select the samples. The data collection tool consisted of part I andpart II.Part I – Dealt with the interview schedule for demographic data which consist of 13 items used to collect thesample characteristics such as age in years, gender, religion, educational status, past occupation, source of income,marital status, diet, on a therapeutic diet, practice of regular exercise, presence of any physical illness, aware ofinformation about Tai Chi Chuan exercise, if yes.Part II - Berg balance scale was used to assess the balance control in older people.Results of the StudyAssociation between the body balance status and demographic variablesa) Experimental GroupThe finding of this study in the experimental group showed that there was significant association between the levelof balance control and demographic variables such as age and past occupation.

Hence theresearch hypothesis was accepted at 0.05 level of significance and null hypothesis was rejected.Discussion: The overall findings of the study clearly showed that effectiveness of tai CHI CH-UAN exerciseson balance control among older people living in selected old age homeswas more effective for the Experimentalgroup than the Control group.

Training of young medical professionals: implementation of modern training concepts, taking into account the changed framework conditions for training—a pilot project for operational subjects

IntroductionFor years, generations of medical students have complained that practice-oriented learning is neglected in medical studies. Further training assistants also complain about limited opportunities to learn subject-specific practical activities.Material and techniquesWe are presenting a pilot project at the University Women’s Hospital in Homburg, in which medical students complete an endoscopic hands-on course as part of the block internship gynaecology and obstetrics. During the course the students perform classic skills training and hand–eye coordination exercises and learn the first steps in endoscopic suturing (suture and rows of knots). The training concepts used can be implemented on simple boxing trainers and can therefore also be reproduced in clinics or in a private setting.OutcomeAltogether, 73 medical students did participate in the laparoscopy course. We were able to prove that the knotting time for a simple knot can be reduced from an average of 247 s to 40 s (80%) after completing our training programme. Based on the evaluation sheet that the students filled out after the course, we found a very-high acceptance for surgical simulation training within the student cohort.DiscussionPractical surgical exercises can complement the curriculum well and, as we can show with our work, are rated very positively by the students. For students in higher semesters, such practical courses can also provide an insight into the respective subject area and thus counteract the lack of skilled workers in surgical subjects. The practical year should not be the first contact with these practical courses, as at this timepoint a certain favoured subject has often already being chosen by the students.

Effects of 8-week endurance, strength, and coordination exercise interventions on attention in adolescents: a randomised controlled study

ABSTRACT The aim of this study was to test the effect of 8-week endurance, resistance, and coordination training programmes on adolescents’ attention. Adolescent students (N = 96) aged 15–18 years were randomised to one of three exercise intervention groups (endurance, strength, coordination) or to a non-exercise, control group. The random assignment to the study groups was stratified according to participants’ age and gender. The intervention lasted for eight consecutive weeks, with two 50-min training sessions per week. Before and after the exercise intervention, all participants completed the d2-test of attention. A 4 × 2 repeated measures ANOVA with contrast-coded test was used as the main analysis method. The analysis revealed that attentional test performance increased from before to after the exercise intervention for all exercise groups, as compared with the control group. The coordination group showed the highest, and the strength group the lowest, improvements in attentional performance. These results indicate that long-term exercise intervention is in general beneficial for adolescent students’ attention, with the greatest effects being observed in the coordination exercise group. Physical education teachers are encouraged to enrich their lessons with coordinative tasks.

The effect of electromyography triggered electrical stimulation to abdominal muscles on sitting balance, respiratory functions, and abdominal muscle thickness in complete spinal cord injury: a randomized controlled trial.

Complete thoracic spinal cord injury (SCI) results in a loss of innervation to the abdominal muscles, which affects trunk stability and performance of activities of daily living from a sitting position. Respiratory function is also affected, leading to frequent pulmonary complications. Given the importance of trunk stability and respiratory function, we investigated the effects of electromyography triggered electrical stimulation (EMG-ES) applied to the abdominal muscles on sitting balance, respiratory functions and abdominal muscle thickness in individuals with complete thoracic SCI. This randomized controlled study included 34 participants with complete thoracic SCI who were randomly allocated to the experimental group ( n = 17) and the control group ( n = 17). During the 4-week intervention period, the experimental group received EMG-ES to their abdominal muscles, while the control group received isometric abdominal exercises three times per week. Both groups continued with their routine rehabilitation program (active or passive range of motion exercises, stretching, and balance coordination exercises). The primary outcome measures were the modified functional reach test (mFRT) and trunk control test (TCT). Secondary outcome measures included a pulmonary function test (PFT) and the bilateral abdominal muscle thicknesses using ultrasonography. At the end of the study, the experimental group showed significantly greater improvements in both primary outcomes. The mean difference in pre-post changes between the groups for the mFRT area was 242.8 cm² [95% confidence interval (CI): 181.3-329.8; effect size 0.92; P < 0.001] and 5.0 points for TCT (95% CI: 3.9-6.0; effect size 0.98, P < 0.001). The increase in the abdominal muscle thickness was also significantly greater in the experimental group ( P < 0.001) without significant differences in the PFT ( P > 0.05). We conclude that adding EMG-ES of abdominal muscles may further improve sitting balance and abdominal muscle thickness in individuals with complete thoracic SCI.

Development of flexibility of young men of 22-35 years old who are engaged in capoeira

Taking into account a wide arsenal of means of physical training which are used during training sessions of capoeira, it can be referred to the list of the brightest and the most various types of martial arts. This greatly influences the choice of capoeira exercises by young Ukrainians as a means of physical education. Traditionally, one of the defining physical qualities on the way to mastering complex coordination exercises in capoeira is flexibility. The insufficient level of its development leads to a lack of technique. This negatively affects the motivation to train and the final result. Therefore, today, it is important to develop and implement a system of classes that promote the development of flexibility in the training process of capoeirists.&#x0D; The purpose of the study: to experimentally substantiate the system of flexibility development of men of the first mature age engaged in capoeira. Methods of the research. To achieve this goal we used the following methods: analysis and generalization of scientific and methodical literature and documentary materials; pedagogical observation; pedagogical experiment; methods of mathematical statistics. The research was conducted on the basis of the capoeira school "RABO DE ARRAIA" (Dnipro) with men aged 22-35 years. The results of a preliminary study of the level of flexibility development showed an average level of its development, as well as a level below average. Scientific novelty of the study. The system of development of flexibility of capoeiristas of 25-35 years old, with the predominant use of exercises: without an object, with an object and in pairs, was experimentally substantiated. Conclusions. The experimental system involved the performance of exercises without an object, with an object and in pairs, which alternated each training session; in the experimental group; after twelve weeks of training according to the author's system of flexibility development, a significant increase in all test indicators is observed.

Improvement effect of cinnamaldehyde on reserpine-induced Parkinson's disease rat model

In order to study the neuroprotective mechanism of cinnamaldehyde on reserpine-induced Parkinson's disease(PD) rat models, 72 male Wistar rats were randomly divided into blank group, model group, Madopar group, and cinnamaldehyde high-, medium-, and low-dose groups. Except for the blank group, the other groups were intraperitoneally injected with reserpine of 0.1 mg·kg~(-1) once every other morning, and cinnamaldehyde and Madopar solutions were gavaged every afternoon. Open field test, rotarod test, and oral chewing movement evaluation were carried out in the experiment. The brain was taken and fixed. The positive expression of dopamine receptor D1(DRD1) was detected by TSA, and the changes in neurotransmitters such as dopamine(DA) and 3,4-dihydroxyphenylacetic acid(DOPAC) in the brain were detected by enzyme-linked immunosorbent assay(ELISA). The protein and mRNA expression levels of tyrosine hydroxylase(TH) and α-synuclein(α-Syn) in substantia nigra(SN) were detected by RT-PCR and Western blot. The results showed that after the injection of reserpine, the hair color of the model group became yellow and dirty; the arrest behavior was weakened, and the body weight was reduced. The spontaneous movement and exploration behavior were reduced, and the coordination exercise ability was decreased. The number of oral chewing was increased, but the cognitive ability was decreased, and the proportion of DRD1 positive expression area in SN was decreased. The expression of TH protein and mRNA was down-regulated, and that of α-Syn protein and mRNA was up-regulated. After cinnamaldehyde intervention, it had an obvious curative effect on PD model animals. The spontaneous movement behavior, the time of staying in the rod, the time of movement, the distance of movement, and the number of standing times increased, and the number of oral chewing decreased. The proportion of DRD1 positive expression area in SN increased, and the protein and mRNA expression levels of α-Syn were down-regulated. The protein and mRNA expression levels of TH were up-regulated. In addition, the levels of DA, DOPAC, and homovanillic acid(HVA) neurotransmitters in the brain were up-regulated. This study can provide a new experimental basis for clinical treatment and prevention of PD.

Effects of a neuromuscular training program on the performance and inter-limb asymmetries in highly trained junior male tennis players

BackgroundThe objective of this study was to assess the effectiveness of neuromuscular training on the performance of highly trainer junior tennis players. MethodsTwelve male tennis players (age: 13.4 ± 0.36 years; weight: 50.2 ± 6.29 kg; height: 163 ± 4.41 cm) participated and were randomly divided into two groups. The experimental group (EG) performed neuromuscular training that included exercises for speed, strength, throws, agility, jumps and coordination twice a week for a duration of 10 weeks. Performance was evaluated using various variables, including bilateral and unilateral countermovement jump, 30 cm drop jump and horizontal jump, 505 change of direction test conducted with both the right and left legs, 20-m sprint, and overhead 3 kg medicine ball throw. Asymmetries were also evaluated during the unilateral tests. The impact of the training was assessed through the utilization of ANCOVA tests and effect size measurements. ResultsThe results indicated a significant enhancement in the EG, specifically in bilateral vertical jump and horizontal jump, as well as explosive strength and speed. Conversely, the control group (CG) did not display similar advancements. Furthermore, there was no increase in asymmetries. ConclusionThis suggests that the implementation of a neuromuscular training program could prove to be an effective approach in enhancing explosive power in the lower limbs among young competitive tennis players. Finally, this training program could contribute to the enhancement of their physical attributes in lower body of young tennis players.

Interdisciplinary pain therapy in the elderly

Chronic pain in the elderly is becoming increasingly important and is associated with serious health impacts. Therefore, international guidelines demand that pain therapy for the elderly preferably be amultimodal therapy based on abio-psycho-social pain model. Specific psychometric tests and interview guidelines are available for the interdisciplinary pain assessment. Evidence for the effectiveness of multimodal pain therapy in the elderly remains limited. However, controlled clinical trials have shown that these patients benefit-especially if the intervention is adapted to their specific needs. The focus of movement therapy is not only muscle strengthening but also coordination exercises. In individual physical therapy and occupational therapy, everyday solutions can be developed for individual physical limitations that are more frequent in old age. In psychological training, pain acceptance, balancing rest and activity, social integration and dealing with aging are particularly important topics. Relaxation and mindfulness techniques can also favorably affect pain and function. Thus, these are popular with patients and are often adopted in everyday pain management. Pain education is considered useful as an adjunctive measure and can also be increasingly supported by digital media in the elderly. Complementary therapy components include confrontational treatment of fear-avoidance beliefs (the German AMIKA scale, Ältere Menschen in körperlicher Aktion, "older people in physical action") and naturopathic applications as an active self-help strategy. Since it is unclear how long the achieved therapeutic effects last, follow-up care is of particular importance in therapy for older patients.

THE EFFECT OF PHYSICAL THERAPY INTERVENTION AFTER CEREBELLAR RESECTION

A variety of diseases, including gait ataxia, lack of coordination, diminished dexterity, and unsteady posture, can be brought on by cerebellar dysfunction. This case study looks into how a physical therapy program affected a 40-year-old patient's dynamic balance after cerebellar tumour surgery. The patient complained of losing his balance and having uncoordinated motions on the left side of the body. The Timed Up and Go (TUG) test was used to gauge how the Frenkel coordination exercises and balance training affected dynamic balance following cerebellar tumour removal. The patient's muscle strength in the left-side hip extensors, abductors and adductors, knee flexors and extensors, as well as the left-side shoulder, elbow, and wrist flexion and extension, significantly improved.

Knowledge and Attitude Towards Bell's Palsy Rehabilitation Among Physical Therapists in Saudi Arabia: A Cross-Sectional Study.

Bell's Palsy (BP) is an acute lower motor nerve impairment of the facial nerve, causing sudden paralysis on one side of the face and significantly affecting the patient's quality of life. Physiotherapy is critical for rehabilitation after BP, aiding functional recovery. Various physical therapy interventions, such as dry needling, taping, and nerve mobilization, have proven effective in treating BP. However, different rehabilitation approaches and knowledge levels among therapists can result in varying treatment outcomes. Therefore, understanding rehabilitation specialists' knowledge and attitudes towards BP is essential for ensuring effective treatment. To date, no studies have examined the knowledge and attitudes of rehabilitation professionals in Saudi Arabia regarding BP. This study aims to evaluate the knowledge and attitudes of physical therapists in Saudi Arabia regarding the rehabilitation of BP. A cross-sectional observational study was conducted with 150 licensed physical therapists in Saudi Arabia, selected via convenience sampling. Participants completed an anonymous online survey covering demographics, knowledge of, and attitudes toward BP rehabilitation techniques. Descriptive and inferential statistics were used to analyze the data. The participants had a mean age of 33.13 ± 6.85 years, with 68.7% being female. Most held Bachelor's degrees (65.3%) and worked in general hospitals (72.7%). The average knowledge score was 8.99 ± 1.95, indicating moderate knowledge levels. Attitudes towards BP rehabilitation were positive, particularly regarding early intervention, emotional support, and coordination exercises. Significant differences in knowledge and attitudes were observed based on gender, experience, and practice location. Physical therapists in Saudi Arabia demonstrate moderate knowledge and positive attitudes toward BP rehabilitation. Continued professional education and collaboration are recommended to improve clinical standards in treating BP.

O PNLD 2022 e a curricularização da alfabetização na educação infantil

ABSTRACT This article presents research that aimed to analyze the literacy proposals of two textbook collections approved in the PNLD 2022 regarding appropriation of alphabetic writing. As methodological procedures, a documental analysis of volumes 1 and 2 of the Porta Aberta and Bambolê books for children aged 4 and 5, respectively, was carried out. These book collections were the most chosen by Early Childhood Education teachers from public schools in some cities in the state of Pernambuco. Data analysis indicated that both collections, complying with the requirements of the PNLD 2022 public notice, propose work focused on preparing children for literacy with a focus on motor coordination exercises, auditory and visual discrimination and the explicit teaching of relations between the letters of the alphabet and their corresponding sounds. The proposals for teaching reading and writing presented in the analyzed collections contradict what is presented in the DCNEI and BNCC for the Early Childhood Education stage, since they do not prioritize interactions and play, and do not guarantee, in working with children, their basic rights.

Effects of different types of physical exercise on executive function of older adults: a scoping review.

This scoping review examined the impact of physical exercise on executive function (EF) in older adults and investigated the moderating effects of exercise types. We systematically searched four electronic databases for randomized controlled trials (RCTs) investigating the effects of exercise on EF, published until November 26, 2023. The proportions of positive and null/negative effects across all studies were calculated. In total, 91 studies were included in the analysis. Among these, 27 (29.7%) studies employed aerobic exercise interventions for older adults' EF, with 19 (70.4%) studies reporting positive effects. Additionally, 18 (19.8%) studies utilized strength exercise interventions for older adults' EF, with 15 (83.3%) studies demonstrating positive benefits. Furthermore, 32 (35.2%) studies employed coordination exercise interventions for older adults' EF, with 25 (78.1%) studies showing positive benefits. Similarly, 30 (33%) studies applied mixed exercise interventions for older adults' EF, with 25 (83.3%) studies indicating positive benefits. Overall, all four types of physical exercise enhance EF in older adults, with mixed exercises being the most effective.

Use of geometry and featural cues in landmark configurations to reorient DCD children to the VR space: A route-learning study

Background. Working memory-based spatial cognition has attracted the attention of the scientific community in navigation and reorientation projects. The dominant approach considers that spontaneous spatial navigation behavior is based merely on environmental geometry (built and natural environmental objects). In this domain, DCD (Developmental Coordination Disorder) motor skill orientation problems have been frequently associated with poor visuospatial cognition, while immersive VR environments encourage more repetition, allowing for faster motor skill development and recovery. Objective. This pilot study tested the functionality of an immersive VR environment with environmental geometry (rectangular arena rich in symmetry) and featural landmark cues (striped wall, flora) as a route-learning tool for children with motor skill disorders. Methods. Forty DCD children aged 5 to 8 years (20 boys and 20 girls); five (5) 3D reality modeling setups with orthogonality, symmetry, and striped walls as design parameters; and trial walk-through coordination exercises using a predefined visual pathway with different motor control conditions (daylight, darkness). Participants’ path completion rate, path completion time, and walk-through satisfaction were recorded as route-learning performance variables and analyzed statistically. Results/findings. DCD children’s spatial orientation was statistically shown to be more stable and robust (in path completion rates, termination time, and walk-through level of satisfaction) in a virtual 3D environment rich in orthogonality, symmetry, and featural cues as landmarks. In this compound environmental geometry setup, training functionality and immersive learning performance enjoyed an 8.16% better path completion rate, a 12.37% reduction in path completion time, and 32.10% more walk-through satisfaction than reality modeling setups poor in geometry and landmarks. The effectiveness and robustness were validated statistically. Conclusion. Children with motor skill difficulties train and learn better in virtual 3D environments that are rich in orthogonality, symmetry, and featural landmark cues.

Twelve weeks of physical exercise breaks with coordinative exercises at the workplace increase the sulcal depth and decrease gray matter volume in brain structures related to visuomotor processes

Physical exercise can evoke changes in the brain structure. Consequently, these can lead to positive impacts on brain health. However, physical exercise studies including coordinative exercises are rare. Therefore, in this study, we investigated how 12 weeks of physical exercise breaks (PEBs) with coordinative exercises, focusing mainly on juggling tasks, affected the brain structure. The participants were randomly allocated to an intervention group (IG, n = 16; 42.8 ± 10.2 years) and a control group (CG, n = 9; 44.2 ± 12.3 years). The IG performed the PEBs with coordinative exercises twice per week for 15–20 min per session. Before the intervention, after 6 weeks of the intervention, and after 12 weeks of the intervention, participants underwent a high-resolution 3T T1-weighted magnetic resonance imagining scan. Juggling performance was assessed by measuring the time taken to perform a three-ball cascade. A surface-based analysis revealed an increase in vertex-wise cortical depth in a cluster including the inferior parietal lobe after 6 and 12 weeks of training in the IG. After 12 weeks, the IG showed a decrease in gray matter (GM) volume in a cluster primarily involving the right insula and the right operculum. The changes in the GM volume were related to improvements in juggling performance. No significant changes were found for the CG. To conclude, the present study showed that regular engagement in PEBs with coordinative exercises led to changes in brain structures strongly implicated in visuomotor processes involving hand and arm movements.

Effects of yoga exercise in reducing the risk of knee osteoarthritis and fibulin-3 levels among overweight population: a randomized controlled trial

Background and purpose: One of the main risk factors for knee osteoarthritis is overweight. The purpose of this study is to determine the effectiveness of yoga exercise in reducing the risk of knee osteoarthritis and fibulin-3 levels in overweight populations. Methods: This study was a randomized controlled trial involving 24 participants who met the inclusion and exclusion criteria. Participants were randomly divided into two groups: group one was given yoga exercise intervention and group two was given neuromuscular coordination exercise as the control group. Risk of knee osteoarthritis measurements were carried out using The Western Ontario and McMasters University Osteoarthritis Index (WOMAC). Fibulin-3 measurement used ELISA technique using human fibulin-3 kit, FBLN3 BT-LABkit 96T E4667Hu. Results: Participants of both groups were comparable, except for age where the control group is slightly older. Pre and post-test comparison showed improvement in pain, stiffness, physical function, total WOMAC score, and fibulin-3 levels in both groups. While, the post-test comparison between the two groups showed that yoga group has better scores on all indicators compared to the control groups which was statistically significant (p≤0.001). Conclusion: Both interventions are effective in reducing the risk of knee osteoarthritis and fibulin-3 levels, but yoga showed better result. We recommend yoga training to reduce the risk of knee osteoarthritis compared to conventional training. Future research is needed to measure other knee osteoarthritis biomarkers that describe the pathological process of knee osteoarthritis.

Motor-cognitive exercise with variability of practice and feedback improves functional ability and cognition in older individuals.

Motor-cognitive dual-task training seems the most favorable form of exercise for functional and cognitive improvements in older individuals. The optimal exercise regime is still uncertain, and the potential benefits of qualitative parameters of exercise prescription such as feedback provision and practice variability are mostly unknown. To verify the effects of a motor-cognitive dual-task training with feedback provision and variability of practice for improving functional ability and cognition in older individuals. Thirty individuals (3 men) aged over 65years were tested on walking speed, static and dynamic balance, lower limb strength, and cognition before and after a 5-week motor-cognitive intervention. Training consisted of twice weekly, 30min gross-motor coordination exercises with variable practice conditions combined with stimulus-response cognitive tasks generated by an interactive device. Participants were divided into an experimental group and a control group, respectively receiving and nonreceiving feedback during training. A 2 × 2 ANOVA was used to verify the effects of training. Both groups improved static and dynamic balance (p < 0.05), walking speeds (p < 0.05), lower limb strength (p < 0.05) and cognitive functions with greater gains observed in the experimental group (p < 0.01). Variability of practice applied to motor-cognitive dual-task training is effective for improving, in only 5 weeks, functional ability and cognitive processing in older individuals. These changes were possibly afforded through motor and cognitive enhancement induced by exercise complexity. Provision of feedback seems to particularly benefit cognitive functions. Brief motor-cognitive dual-task training using practice variability and feedback seems effective for counteracting the age-related cognitive and functional decline.

Совершенствование вестибулярной устойчивости студентов средствами трансдинамических двигательных действий

Any mastering of the movements technique, which is formed as a result of prolonged physical or sports exposure, depends on the activity coordination of the central nervous processes and the working muscles. In order to quickly achieve the result of improving the vestibular stability, a technique was developed aimed at changing the state of consciousness by focusing attention on performing coordination exercises along the specified trajectories and requiring the completion of tasks for a normative period of time. The purpose of the study is to determine the influence of transdynamic motor actions on improving the vestibular stability of students – future architects, mining technicians, environmental engineers, occupational safety specialists, water use engineers, automation engineers, etc. The results of the implementation of the author’s methodology for improving the vestibular stability in the course of training sessions with 42 students and preparing them for professional activity in the agrarian region were presented. In addition to the vestibular stability, the development processes of key physical qualities during the academic year were studied. The effectiveness of the technique has been proved, which contributed to the improvement of the vestibular stability by 10–15% in 8–10 practical sessions after a long absence of motor activity, and can also be used in game sports to increase athletic performance by 5–8% per year.

Use of exercises with increased coordination complexity in the training process of young female volleyball players aged 13-14 years

Background and Study Aim. In the context of training young female volleyball players, understanding the criteria, extent, and impact of exercises with heightened coordination complexity becomes crucial. This study aims to determine the evaluation criteria, scope, and effects of incorporating exercises with elevated coordination demands on the specific athletic readiness of young female volleyball players aged 13–14 years. Material and Methods. The study involved female volleyball players aged 13–14 years (n=24) with an average of 4 years of professional experience. Participants were divided into a control group (n=12) and an experimental group (n=12). Prior to the study, both children and their parents were thoroughly informed about the research procedures, and parental consent was obtained for participation. The coordination exercises were categorized into five groups, each assigned a complexity rating from 1 to 5. The assessment utilized a battery of tests. Results. The findings reveal that coordination training yielded a more pronounced advancement in the development of various coordination abilities among female volleyball players in the experimental group, as compared to those in the control group. A statistically significant enhancement (p&lt;0.05) was evident across all indices of coordination readiness within the experimental group. In contrast, the control group demonstrated notable progress only in 3 out of 10 instances (p&lt;0.05). In the control group, noteworthy increases (p&lt;0.05) were observed in spatial orientation, motor activity restructuring, and response indicators. Female volleyball players in the experimental group exhibited substantial improvement (p&lt;0.05–0.001) across all indicators of technical readiness, including reception, attack hit, serve, and ball pass. Conversely, the control group players showed comparatively less remarkable changes in this aspect of readiness, with significant enhancement (p&lt;0.05) identified in three parameters. Conclusions. The strategic incorporation of exercises with progressively heightened coordination demands emerges as a valuable approach in substantially enhancing the range of coordination abilities among young female volleyball players. Recognizing this factor provides the means to expedite and optimize the mastery of motor skills more effectively.

What type of exercises should older adults engage in to improve fall efficacy and physical fitness related to falling?

This study aimed to examine the effects of exercise interventions developed over the past 10 years to prevent falls among older adults. Cochrane, PubMed, and Embase databases were systematically searched on November 3, 2022, using the following keywords: "elderly" or "aged" and "fall prevention exercise" and "randomized controlled trial." A total of 918 articles were retrieved, and finally, 18 studies were included in the meta-analysis. main conclusions were as follows: fall prevention exercises showed moderately positive effects on balance, gait, mobility, physical function, lower limb power, and strength, but low effects on proprioception, vision, and reaction speed. The effect sizes were highest when the intervention period was 1-24 weeks, time was 31-60 min, and frequency was thrice per week. Place of intervention (home, community, laboratory) and age (>75 years, <75 years) showed similarly moderate effect sizes. A combined program that includes balance, co-ordination, and resistance exercises is appropriate to improve fall-related fitness and fall efficacy in community-dwelling older individuals.
