Objective: Mental fatigue is caused by long-term cognitive activities and lead to changes in motor coordination. The purpose of this study was to investigate the effect of yoga training on balance and knee proprioception after mental fatigue in amateur male athletes. Methods: In this quasi-experimental study, 36 amateur male students were voluntarily selected as study samples and randomly divided into training (n=18) and control (n=18) groups. The training group received yoga exercises for eight weeks, three sessions per week, each for one hour. Mental fatigue was induced by 45 minutes of cognitive activity (Stroop test). Before and after mental fatigue and intervention, their dynamic balance was measured by Y-balance test and the semi-dynamic balance by Lafayette stability platform. Data were analyzed in SPSS v.22 software using paired sample t-test at the significant level of 0.05. Results: The effects of time and group×time interaction on dynamic and semi-dynamic balances (P=0.0001), and on active and passive knee proprioception (P=0.0001) were significant after yoga training. Conclusion: There were significant improvements in balance and knee proprioception of amateur athletes after yoga training. Further studies should be conducted to introduce solutions to the occurrence of mental fatigue in these athletes.

Maximal strength, muscular endurance, maximal aerobic power, and anaerobic capabilities, power are needed to have victory for wrestlers in a wrestling competition.The aim of the study is to investigate the effect of acute muscular fatigue on static and dynamic balance performances in elite wrestlers. Ten elite male wrestlers (25 ± 2.3 years, 181 ± 6.5 cm, 84 ± 4.2 kg) participated in the study voluntarily. Participants were undertaken dynamic and static balance test before fatigue exercise (in Cybex) and immediately after fatigue exercise, theywere undertaken dynamic and static balance test again. SPSS packet program was used to evaluate the data. There were no statistically significant differences in static and dynamic balance before and after fatigue. The results show that wrestlers’ balance is not affected by muscular fatigue, so there is no need for balance exercise after fatigue at least according to this study.

The Impact

The objective of this study is to assess the impact of deceleration training method on improving dynamic balance skills of young soccer players in comparison with the conventional training methods. This study included 26 young soccer players (mean age: 13.54±1.48, height: 154.98±12.44, weight: 46.16±11.06, Body Mass Index 18.96±2.21 kg/m2, fat percentile 18.22%±3.22). Thirteen players participated in the deceleration training group (DTG) group and thirteen players participated in the conventional training group (CTG). The training programs were executed on three nonconsecutive days in a week for a total of eight weeks. Y-balance tests were conducted both before and after the eight week training programs. The differences between the averages were analyzed with Wilcoxon, comparison between the groups were analyzed with Mann-Whitney-U post hoc analyses. There was no difference in left-right balance variation (p > 0.05) performance measurements between DTG and CTG before the exercise program. However, after the 8 week training programs, the performance measurements between DTG and CTG were significantly different (p < 0.05) and the dynamic balance skill development of the DTG were more advanced. Based on these results, the deceleration training method seems to be a more effective method in developing dynamic balance skills than conventional training methods.

Context:  Ankle sprains are one of the most common injuries in the physically active population. Previous researchers have shown that supporting the ankle with taping or bracing is effective in preventing ankle sprains. However, no authors have compared the effects of self-adherent tape and lace-up ankle braces on ankle range of motion (ROM) and dynamic balance in collegiate football players. Objective:  To examine the effectiveness of self-adherent tape and lace-up ankle braces in reducing ankle ROM and improving dynamic balance before and after a typical collegiate football practice. Design:  Crossover study. Setting:  Collegiate athletic training room. Patients or Other Participants:  Twenty-nine National Collegiate Athletic Association Division I football athletes (age = 19.2 ± 1.14 years, height = 187.52 ± 20.54 cm, mass = 106.44 ± 20.54 kg). Intervention(s):  Each participant wore each prophylactic ankle support during a single practice, self-adherent tape on 1 leg and lace-up ankle brace on the other. Range of motion and dynamic balance were assessed 3 times for each leg throughout the testing session (baseline, prepractice, postpractice). Main Outcome Measure(s):  Ankle ROM for inversion, eversion, dorsiflexion, and plantar flexion were measured at baseline, immediately after donning the brace or tape, and immediately after a collegiate practice. The Y-Balance Test was used to assess dynamic balance at these same time points. Results:  Both interventions were effective in reducing ROM in all directions compared with baseline; however, dynamic balance did not differ between the tape and brace conditions. Conclusions:  Both the self-adherent tape and lace-up ankle brace provided equal ROM restriction before and after exercise, with no change in dynamic balance.

OBJECTIVE: To verify if sleep disorders and differents starting time to school have impaired motor skills in 5-year-old children. METHOD: Cross-sectional design consisting of 132 children with sleep disorders and 136 normal controls of the public school in the city of São Paulo. The group with sleep disorders was identified based on a questionnaire, and motor tests for global motor coordination, fine motor coordination, perceptual-motor coordination, and static and dynamic balance were applied in all children. RESULTS: In the static balance test, more specifically in the sharpened Romberg (Tandem) test, 34% of boys from the study group, who studied in the morning, failed the test (p < 0.05). In the single leg stance test, 62% of boys from the study group who studied in the morning failed (p< 0.05). CONCLUSION: This study suggests that sleep disorders may interact with the school period and alter motor performance, especially in boys studying in the morning.

The aim of this study was to examine the effect of mental fatigue on postural sway under different sensory conditions in healthy older adults and in persons with chronic stroke (PwCS). Thirty healthy older adults (> 60 years old), randomly separated into experimental and control groups, as well as 15 PwCS participated in this study. Experimental groups were asked to stand on a force platform wearing seven inertial sensors while performing the Sensory Organization Test (SOT) under two cognitive conditions (single- and dual-task) before and after a mental fatigue task (stop-signal task for 60 min). The control group performed the same protocol before and after watching a movie for 60 min. Changes in subjective fatigue was assessed by the NASA Task Load Index and psychophysiological workload was assessed by heart rate variability (HRV). Postural sway was assessed by calculating the Jerk and root mean square (RMS) of center of mass (COM). Higher Jerk and RMS of COM (p < 0.05) were observed after the mental fatigue task in both healthy older adults and PwCS during SOT, which was not observed in the control group (p > 0.05). Additionally, postural sway increased in the three groups as the SOT conditions became more challenging. Our results indicate that mental fatigue, induced by sustained cognitive activity, can impair balance during SOT in older adult and stroke populations.

The aims of this study were to analyse the effects of unstable and stable bodyweight neuromuscular training on dynamic balance control and to analyse the between-group differences after the training period. Seventy-seven physically active young adults (48 males, 29 females, 19.1 ± 1.1 years, 170.2 ± 9.2 cm, 64.1 ± 10.7 kg) were distributed into an unstable training group (UTG), a stable training group (STG), and a control group (CG). Training was conducted three times a week for nine weeks. Pre-intervention and post-intervention measures included dynamic balance control using a Y Balance Test (YBT), anterior (A), posteromedial (PM), and posterolateral (PL) reach direction. A mixed ANOVA was executed to test the within-subjects factor and the between-subjects factor. Statistically significant differences were found for all YBT measures within groups (p = 0.01) and between groups (p = 0.01). After the intervention, UTG and STG presented meaningfully improved results in all YBT measures (A: 7%, p = 0.01; 4%, p = 0.02, PM: 8%, p = 0.01; 5%, p = 0.01, PL: 8%, p = 0.01; 4%, p = 0.04, respectively). No statistical changes were found for any of the measures in the CG. After the intervention, significant differences were observed between the UTG and CG for the YBTA and PM (p = 0.03; p = 0.01). The results suggest that neuromuscular training using an unstable surface had similar effects on dynamic balance control as training using a stable surface. When compared to CG, UTG showed better performance in YBTA and PM.

Objective: Patellofemoral Pain Syndrome (PFPS) is one of the most common disorders of the knee joint. It is characterized by pain, reduced proprioception, and altered pattern of vastus muscle activation, which effectively maintain the balance needed for performing daily living activities such as walking and running. One treatment method that can reduce pain and improve balance in people with PFPS is Kinesiology Taping (KT). Considering the physiological and anatomical differences in the knee structure of men and women and the importance of studying the effect of KT on the dynamic balance of men with PFPS, this study aims to compare the effect of KT on dynamic balance and pain of men and women with unilateral PFPS. Materials & Methods: This is a quasi-experimental and non-randomized clinical trial. The participants were 30 males and 31 females aged 18-40 years suffering from unilateral PFPS. They were recruited using a convenience sampling method. First, the subjects performed the Y-balance test three times in each of the anterior, posteromedial, and posterolateral directions. The maximum score obtained from the three repetitions in each direction was divided by the limb length and recorded in percentage as a dynamic balance score. After 5 minutes of rest and performing initial tests, the subjects performed the intervention. In this stage, KT with a tension equal to 50%-75% of its initial length was applied on the patella of the involved limb to cause medial glide. The effectiveness of KT was examined under a single-leg squat-test. For this purpose, all subjects performed unilateral squatting on their affected leg for 10 seconds with 45 degrees of knee flexion before and after KT, while their pain level was recorded using the visual analog scale. In case of a 50% reduction in pain, the subjects were allowed to enter the final stage (performing the Y-balance test); otherwise, patellar taping was repeated to obtain the appropriate pain reduction. Results: Within-group comparison of balance parameters before and after KT using the paired t-test showed an increase in the reach distance at three directions in the Y-balance test, revealing a significant improvement in the dynamic balance following KT (P<0.05). According to the independent t-test results, there was no significant difference in balance parameters between males and females before and after the intervention (P>0.05). Moreover, the pain was significantly reduced in both genders after KT (P<0.05), but its difference between men and women was not statistically significant (P>0.05). Conclusion: KT is an appropriate therapeutic intervention for improving dynamic balance and reducing pain in people with PFPS. It seems that KT has the same effect on dynamic balance and pain of women and men with PFPS.
