Context:Core training specifically for track and field athletes is vague, and it is not clear how it affects dynamic balance and core-endurance measures.Objective:To determine the effects of a 6-week core-stabilization-training program for high school track and field athletes on dynamic balance and core endurance.Design:Test–retest.Setting:High school in north central West Virginia.Participants:Thirteen healthy high school student athletes from 1 track and field team volunteered for the study.Interventions:Subjects completed pretesting 1 wk before data collection. They completed a 6-wk core-stabilization program designed specifically for track and field athletes. The program consisted of 3 levels with 6 exercises per level and lasted for 30 min each session 3 times per week. Subjects progressed to the next level at 2-wk intervals. After 6 wk, posttesting was conductedMain Outcome Measures:The subjects were evaluated using the Star Excursion Balance Test (SEBT) for posteromedial (PM), medial (M), and anteromedial (AM) directions; abdominal-fatigue test (AFT); back-extensor test (BET); and side-bridge test (SBT) for the right and left sides.Results:Posttest results significantly improved for all 3 directions of the SEBT (PM, M, and AM), AFT, BET, right SBT, and left SBT. Effect size was large for all variables except for PM and AM, where a moderate effect was noted. Minimal-detectable-change scores exceeded the error of the measurements for all dependent variables.Conclusion:After the 6-wk core-stabilization-training program, measures of the SEBT, AFT, BET, and SBT improved, thus advocating the use of this core-stabilization-training program for track and field athletes.

AbstractThe purpose of this study was to examine the effectiveness of a 6-week core stabilization training program (CSTP) in improving dynamic balance and back-extensor endurance of horse riders; and develop a measurement tool in assessing the dynamic postural stabilization endurance for horse riders. Twelve male horse riders (age: 23.58 ± 1.93 years; height: 165.09 ± 4.60 cm; weight: 56.53 ± 4.75 kg; experience in horse racing: 1.75 ± 0.34 years) completed 12 training sessions in 6 weeks. Subjects performed the CSTP with two progressions. CSTP started with the basic consciousness activation exercises, and then eliminated visual feedback in dynamic balance task on unstable surfaces and finished with switching the center of gravity. Moderate-to-large difference was demonstrated in the Y-Balance test scores for right leg (102.81 ± 8.32 vs 106.471 ± 4.35 cm, d = 0.55, 95% CL 0.00 to 1.08) and left leg (102.04 ± 3.20 vs 106.29 ± 3.62 cm, d = 1.25, 95% CL 0.41 to 2.05) following 6 weeks CSTP. However, trivial to small differences was reported between left and right leg in pre (d = 0.12, 95% CL − 0.49 to 0.73) and post 6-week CSTP (d = 0.04, 95% CL − 0.69 to 0.78). Biering–Sørensen test (BST) shows largely greater performance after 6-week CSTP (98.3 ± 30.1 vs 131.8 ± 19.0 s, d = 1.33, 95% CL 0.54–2.09). A novel measurement, Swiss ball four-point kneeling test was shown to be correlated with the change in BST (r = 0.633).

Context:The Upper Quarter Y-Balance Test (YBT-UQ) is a unique movement test where individuals perform at the limits of their stability, requiring the coordination of balance, proprioception, range of motion, and stabilization. It is not yet clear if performance on the YBT-UQ differs between sports with dissimilar emphasis on upper-extremity performance.Objective:To compare performance on the YBT-UQ between wrestlers, whose sport requires some degree of closed-chain activity, and baseball players, whose sport is primarily open kinetic chain in nature.Design:Cross-sectional.Setting:High school preparticipation physical assessment.Participants:24 healthy high school male wrestlers (mean age 16.12 ± 1.24 y) and 24 healthy high school male baseball players (mean age 15.79 ± 1.25 y).Interventions:All subjects performed the YBT-UQ, which requires reaching in 3 directions while maintaining a push-up position.Main Outcome Measures:The variables of interest include the maximum reach in each direction, as well as the composite score. In addition, asymmetries between limbs for each reach direction were compared.Results:Wrestlers performed significantly better than baseball players in the medial direction, inferolateral direction, and in composite scores. In the medial direction, wrestlers exhibited greater scores (P < .01) on both left and right limbs, 10.5 ± 10.2%LL and 9.95 ± 10.2%LL, respectively. Significant differences (P < .01) were also observed in the inferolateral direction, with a difference of 11.3 ± 12.0%LL on the left and 8.7 ± 11.0%LL on the right. Composite scores were higher (P < .01) for the wrestlers, with a difference of 7.0% on the left and 7.1% on the right.Conclusions:This study suggests that wrestlers perform better on the YBT-UQ than baseball players. The findings may suggest sport-specific normative data for the YBT-UQ in high school athletes.

Background. Core stability (or core strengthening) has become a well-known fitness trend that has started transcending into sports medicine. It has become a common practice to incorporate balance tasks into the training program for athletes who want to improve performance and prevent injuries. Hypothesis. We suggest that core stabilization and balance training with closed eyes will be more effective than training with open eyes. The aim of the study was to evaluate the effect of core stabilization training with open eyes versus closed eyes on balance and stability of young football players. Methods. Fourteen healthy young football players aged 10–12 years were assessed for pre and post core stabilization training using two balance tests: Stork Balance Test (SBT) and Modified Star Excursion Balance Test (mSEBT), and one test for core stability ‒ McGill Core Stability Test (MCST). The intervention included twelve twenty-minute training sessions each of them involved six core strengthening exercises. One group performed exercises with open eyes, and another with eyes closed. Results. Core stability exercises with eyes closed as well as the same exercise done with eyes open insignificantly improved dynamic balance and core stability, but significantly improved the static balance of the subjects. Conclusion. After applying training with closed eyes as well as eyes open, core stability and balance of young football players increased insignificantly. There were no significant differences in core stability and balance training between training with eyes open and eyes closed.Keywords: core stabilization training, balance, open eyes, closed eyes.

Balance disorders have a high prevalence among elderly people in developed countries, and falls resulting from balance disorders involve high healthcare costs. Therefore, tools and indicators are necessary to assess the response to treatments. Therefore, the aim of this study is to detect relevant changes through minimal detectable change (MDC) values in patients with balance disorders, specifically with vertigo. A test-retest of a static and dynamic balance test was conducted on 34 healthy young volunteer subjects using a portable stabilometric platform. Afterwards, in order to show the MDC applicability, eight patients diagnosed with balance disorders characterized by vertigo of vestibular origin performed the balance test before and after a treatment, contrasting the results with the assessment by a specialist physician. The balance test consisted of four tasks from the Romberg test for static balance control, assessing dynamic postural balance through the limits of stability (LOS). The results obtained in the test-retest show the reproducibility of the system as being similar to or better than those found in the literature. Regarding the static balance variables with the lowest MDC value, we highlight the average velocity of the center of pressure (COP) in all tasks and the root mean square (RMS), the area, and the mediolateral displacement in soft surface, with eyes closed. In LOS, all COP limits and the average speed of the COP and RMS were highlighted. Of the eight patients assessed, an agreement between the specialist physician and the balance test results exists in six of them, and for two of the patients, the specialist physician reported no progression, whereas the balance test showed worsening. Patients showed changes that exceeded the MDC values, and these changes were correlated with the results reported by the specialist physician. We conclude that (at least for these eight patients) certain variables were sufficiently sensitive to detect changes linked to balance progression. This is intended to improve decision making and individualized patient monitoring.

The Relationship

Context:Ankle-dorsiflexion range of motion has often been measured in the weight-bearing condition in the clinical setting; however, little is known about the relationship between the weight-bearing-lunge test (WBLT) and both ankle kinematics and performance on dynamic postural-control tests.Objective:To examine whether ankle kinematics and performance on the Lower Quarter Y-Balance Test (YBT-LQ) are correlated with results of the WBLT using an inclinometer and tape measure.Design:Cross-sectional.Setting:University motionanalysis laboratory.Participants:30 physically active participants.Interventions:None.Main Outcome Measures:The WBLT was evaluated using an inclinometer and a tape measure. The reach distances in the anterior, posteromedial, and posterolateral directions on the YBT-LQ were normalized by limb length. Ankle dorsiflexion during the YBT-LQ was recorded using a 3-dimensional motion-analysis system. Simple linear regression was used to examine the relationship between the WBLT results and both ankle dorsiflexion and the normalized reach distance in each direction on the YBT-LQ.Results:The WBLT results were significantly correlated with ankle dorsiflexion in all directions on the YBT-LQ (P < .05). A strong correlation was found between the inclinometer measurement of the WBLT and ankle dorsiflexion (r = .74, r2 = .55), whereas the tape-measure results on the WBLT were moderately correlated with ankle dorsiflexion (r = .64, r2 = .40) during the anterior reach on the YBT-LQ. Only the normalized anterior reach distance was significantly correlated with the results for the inclinometer (r = .68, r2 = .46) and the tape measure (r = .64, r2 = .41) on the WBLT.Conclusions:Inclinometer measurements on the WBLT can be an appropriate tool for predicting the amount of ankle dorsiflexion during the YBT-LQ. Furthermore, WBLT should be measured in those who demonstrate poor dynamic balance.

Context:Proper functioning of the intrinsic foot musculature (IFM) is essential in maintaining the integrity of the medial longitudinal arch (MLA). Improper functioning of the IFM leads to excessive pronation of the foot, which has been linked to various pathologies. Therefore, training the IFM to avoid excessive pronation may help prevent some of these pathologies; however, it is not clear how to train these muscles optimally.Objective:To investigate the effects of 2 different types of IFM training on the height of the MLA and static- and dynamic-balance task performance.Design:Randomized controlled trial, repeated-measures mixed-model design.Setting:University biomechanics laboratory for testing and a home-based training program.Participants:24 healthy, university-age volunteers (3 groups of 8) with no history of major lower limb pathology or balance impairment.Interventions:One experimental group performed 4 wk of the short-foot exercise (SFE) and the other performed 4 wk of the towel-curl exercise (TCE). Participants were asked to perform 100 repetitions of their exercise per day.Main Outcome Measures:Navicular height during weight bearing, the total range of movement of the center of pressure (COP) in the mediolateral (ML) direction for a static-balance test and a dynamic-balance test.Results:There were no differences in the navicular height or static-balance tests. For the dynamic-balance test, all groups decreased the ML COP movement on the dominant limb by a small amount (~5 mm); however, the SFE group was able to decrease COP movement much more than the TCE group in the nondominant limb.Conclusions:The SFE appeared to train the IFM more effectively than the TCE; however, there were differing results between the dominant and nondominant legs. These imbalances need to be taken into consideration by clinicians.

Abstract Background: Multiple sclerosis is a chronic and disabling neurological disease among young people. One of the major complaints in patients with multiple sclerosis (PWMS) is falling. There are a number of factors that cause falling, including: balance disorder and spasticity. Core stability (CS) exercises such as trunk muscle strengthening exercise can improve balance and mobility and reduce falling. Dynamic neuromuscular stabilization (DNS) exercise is a new functional rehabilitation strategy that optimizes motor function based on the principles of developmental kinesiology. This trial will evaluate the effectiveness of DNS in comparison to CS on balance, spasticity, and falling in PWMS.Methods: A total of 66 PWMS, between 30 and 50 years old and expanded disability status scale (EDSS) between 2 to 5, will be recruited from Tehran hospitals to participate in this 2-armed parallel study. Participants will be randomly divided into two groups to receive CS exercise or DNS exercise. All participants will receive exercise treatment for 15 sessions during a period of 5 weeks (3 sessions per week). Primary outcome measures will be trunk function and balance. Falling rate, fear of falling, patient mobility, as well as spasticity, will be measured as secondary outcomes. All outcome measures will be measured at baseline, the day after the completion of the 15th session, and after three months.Discussion: Dynamic neurostabilization exercises utilizes the subconscious stimulation of special zones to reflexively mediate the diaphragm and other core stabilization muscles, which is extremely effective for individuals with reduced somatosensory or movement awareness. Findings from the proposed study are expected to benefit the knowledge base of the physiotherapist, and it can be a good alternative for the rehabilitation program and even reduce medication use in patients with multiple sclerosis. These exercises are easy to understand and applicable for these patients and their partners as well.Trial registration: The trial was registered in Iran registry organization with code IRCT20140222016680N5 and was approved on April 7th, 2020.

Objective: Since direct foot kick is one of the most important strikes in Jeet Kune Do, its effectiveness depends on both the force of the hit and balance control during and after the hit execution, this study undertaken to examine the effect and persistence of eight-week of core stability training on balance and force of a direct foot kick of elite young male Jeet Kune Do (Wushu) athletes. Methods: 24 elite young Jeet Kune Do athletes were randomly assigned to an experimental and a control groups. The experimental group performed the core stability training program for eight consecutive weeks. Static (stork test), dynamic test (tandem test) and force of a direct foot kick of the athletes in both groups were measured in three stages including before, after (eight weeks of core stability training) and a 4-week follow-up detraining period. Results: The results showed that core stability training had a significant and persistent effect on static and dynamic balance. However, the training program had no significant effect on the force production of a direct foot kick after a 4-week of detraining period. Conclusion: It seems that the core stability training program improves the neuromuscular system function by strengthening the muscles of the core area. This in turn prevents the dislocation of the center of gravity outside the base of support and decreases its oscillation (displacement), therefore, as a result of persistence effect of the program, balance ability and direct kicking power improves.
