Objective: To investigate the effects of a 6-week integrated training program on the ankle joint reposition sense and postural stability in ballet dancers. Methods: Sixteen female ballet dancers participated in the study and underwent a 6-week integrated training program consisting of plyometric, proprioception and core stability exercises along with a home program involving additional ankle muscle strengthening and stretching. The ankle joint reposition tests and the parameters of the center of pressure (COP) while performing grand-plie (deep squatting) and releve en demi-pointe (standing on balls of foot) movements were measured before and after training. Results: After 6 weeks, participants showed significantly smaller absolute ankle joint reposition errors in dorsiflexion (p = 0.031), plantarflexion (p = 0.003) and eversion (p = 0.019) compared to the pre-training measurement. Furthermore, after training, a significantly slower average COP speed at pre-equilibrium during grand-plie movement (p = 0.003) and pre-equilibrium phase of releve en demi-pointe (p = 0.023) were observed. In addition, the maximum COP displacement in the medial-lateral direction was significantly smaller at pre-equilibrium phase during grand-plie (p = 0.044) and releve en demi-pointe movements (p = 0.004) after training. Conclusions: The 6-week integrated training program improved the ankle joint reposition sense and postural control in the medial-lateral direction during grand-plie and releve en demi-pointe movements.

Abstract Background: Ballet dancers are at high risk of ankle sprain. As a result, effective training programs are required for ballet dancers to minimize injury occurrence and improve their balance ability. Our purpose was to investigate the effects of a 6-week integrated training program on the ankle joint position sense and postural stability in ballet dancers.Methods: Twenty-nine female ballet dancers were recruited to the study. Sixteen of the dancers underwent a 6-week integrated training program consisting of plyometric, proprioception and core stability exercises. The remaining ballet dancers performed no additional training, but continued regular ballet practice as usual. For both groups, ankle joint position sensing tests were performed before and after training. Furthermore, for the training group, the postural stability was assessed by measuring the average speed of the center of pressure (COP) and the maximum ankle joint displacements while performing grand plie (deep squatting) and releve en demi-pointe (standing on balls of foot) movements.Results: After 6 weeks, both groups showed significantly smaller absolute ankle joint reposition errors in plantarflexion and eversion. Furthermore, the training group showed a significantly smaller ankle joint reposition error in dorsiflexion. The training group also showed a significantly slower average COP speed and smaller maximum COP displacement in the medial-lateral direction.Conclusions: The 6-week integrated training program improved the ankle joint position sense in dorsiflexion and the postural control in the medial-lateral direction while performing grand-plie and releve en demi-pointe movements. Thus, this integrated training program can be suggested for dancers in order to improve ankle position sense and postural stability during ballet movements.

The purpose of this study was to determine the effect of plantar flexor and dorsiflexor fatigue on postural sway amplitude during unilateral, or one-legged, stance. It was hypothesized that plantar flexor and dorsiflexor fatigue would increase unilateral postural sway amplitude. Eight uninjured male subjects participated in pre- and postfatigue unilateral stability tests. Selected parameters describing medial-lateral (ML) and anterior-posterior (AP) postural sway were measured on a Chattecx Balance System before and after an isokinetic fatigue protocol. The fatigue protocol resulted in a significant increase in ML postural sway amplitude (p< 0.05) and an increase in AP sway amplitude (p= 0.065). Previously, links have been established between increased postural sway amplitude and ankle joint injury. Thus, fatigue of the plantar flexors and dorsiflexors, which increased postural sway amplitude, may render the ankle joint susceptible to injury. Induced ankle muscle fatigue may represent a valid paradigm to study the causes of traumatic ankle joint injury.

Introduction: Generally, core stability exercise as a training program is needed in almost kind of sport including paddle, analysis of movement in any kind of paddle sport such as kayak, canoe, or even rowing have been showed that the activity of core stability muscles are really needed. Purpose: purpose of this research is to know the effectivity of core stability exercise replenishment to increase sculling speed in paddle training program. Methods: This research is experimental with treatment by subject design project, involving 15 paddle athletes which divided into two groups and consists of II periods which are, Period I and Period II. In the 1st period, the athletes were given extra core stability exercise along with their normal paddling routine mean while in the 2nd period, the athletes only doing their normal paddling routine. Each period do the trial in 6 weeks, so this reseach took 12 weeks. In 1st period, the subjects were given extra core stability training 3 times a week along with their normal paddling routine where as subjects in period II only do their normal paddling routine. Results: The used of parametric paired t test is to know the difference of sculling speed before and after the trials were given. To period I pre test value is 3.80 ± 0.26 meters/second while the post test value is 4.06 ± 0.41 meters/second and the value 0.001 (p<0.05)mean while the 2nd period use Wilcoxon signed rank test to know the difference of sculling speed between before and after the trial were given resulting pre test value 3.80 ± 0.22 meters/second and post test value 3.91 ± 0.27 meters/second while the p value is 0.004 (p<0.05). After 12 weeks of sculling speed test between both period using Wilcoxon signed rank test and resulting obvions with period I value 0.26 ± 0.20 meters/second and period II value is 0.11 ± 0.12 meters/second along with p value 0.001 (p<0.05). Conclusion: Therefore, based on the result of my research test, we can concluded that the addition of core stability exercise in paddle training program is more effective to increase sculling speed.

The purposes of this study were (a) to determine the reliability of the Nicholas hand-held dynamometer for measuring scapular adductor strength and (b) to determine if isokinetic strengthening of the scapular adductors while horizontally abducting the shoulder is more effective than strengthening the scapular adductors while extending the shoulder. An isometric make test was used to determine scapular adductor strength before and after a 6-week training program. Intraclass correlation coefficient indicated high pretest and posttest reliability. The individuals who trained the scapular adductors while horizontally abducting the shoulder showed greater increases in mean force values (20.49 kg pretest to 31.74 kg posttest) than the group combining scapular adduction with shoulder extension (19.61 kg pretest and 25.52 kg posttest). ANOVA showed a significant interaction between group and time. It may be more effective to isokinetically strengthen the scapular adductors with shoulder horizontal abduction rather than shoulder extension as a combined movement.

The purpose of the study was to compare postural control in static standing in young adults with and without Down syndrome (DS), with eyes closed and eyesopen, before and after an 18-wk dance-based training program. The study included 11 young people with DS age 20.5 (1.3) yr and 11 without DS age 20.2 (2.0) yr.All parameters were recorded before and after the training program. Parameters related to center of pressure (COP; closed and open eyes) were recorded from aplatform with the participant in bipedal standing position during 30 s. The results suggest that young people with DS have worse COP control in both visual conditions (closed and open eyes) and are affected by visual information in a different way than their peers without DS. In the group of young adults with DS, thedance-based training program improved some parameters related to the use of visual input in controlling COP.

Soccer teams integrate specific exercises into their typical workout programs for injury prevention. The purpose of this study was to investigate whether the incorporation of a brief and supplementary training program that involves eccentric, balance, and core exercises into the weekly soccer schedule can cause positive neuromuscular adaptations. Twenty-one soccer players were randomly allocated to either a training (n = 11) or a control group (n = 10). All players followed their teams’ typical program, consisting of 4–5 soccer-specific sessions plus 1 match, weekly. Training group players additionally performed biweekly, hamstring eccentric, balance, and core stability exercises for 8 weeks. Isokinetic concentric and eccentric peak torque (PT) of the hamstrings and quadriceps, changes in the center of pressure (COP) during a 30 s single-leg stance, and a supine bridge (trunk stability) test were assessed before and after the intervention. After the intervention, a 27% increase in hamstring concentric PT and a 33% reduction in COP sway in the stance test, were observed for the training group only (p < 0.05). These improvements were significant only for the non-dominant leg. Furthermore, the control group displayed an increase in COP sway during the bridge test compared to baseline values (p < 0.05), which reflects a deterioration in postural balance over time. Consequently, incorporating small doses of hamstring eccentric, proprioception, and core stability exercises into a typical training program of youth soccer players improves strength and postural balance in the non-dominant leg, as well as core muscle performance.

Context  Decreased postural stability is a primary risk factor for lower limb musculoskeletal injuries. During athletic competitions, cryotherapy may be applied during short breaks in play or during half-time; however, its effects on postural stability remain unclear. Objective  To investigate the acute effects of a 15-minute ankle-joint cryotherapy application on dynamic postural stability. Design  Controlled laboratory study. Setting  University biomechanics laboratory. Patients or Other Participants  A total of 29 elite-level collegiate male field-sport athletes (age = 20.8 ± 1.12 years, height = 1.80 ± 0.06 m, mass = 81.89 ± 8.59 kg) participated. Intervention(s)  Participants were tested on the anterior (ANT), posterolateral (PL), and posteromedial (PM) reach directions of the Star Excursion Balance Test before and after a 15-minute ankle-joint cryotherapy application. Main Outcome Measure(s)  Normalized reach distances; sagittal-plane kinematics of the hip, knee, and ankle joints; and associated mean velocity of the center-of-pressure path during performance of the ANT, PL, and PM reach directions of the Star Excursion Balance Test. Results  We observed a decrease in reach-distance scores for the ANT, PL, and PM reach directions from precryotherapy to postcryotherapy (P &lt; .05). No differences were observed in hip-, knee-, or ankle-joint sagittal-plane kinematics (P &gt; .05). We noted a decrease in mean velocity of the center-of-pressure path from precryotherapy to postcryotherapy (P &lt; .05) in all reach directions. Conclusions  Dynamic postural stability was adversely affected immediately after cryotherapy to the ankle joint.

Field Epidemiology Training Program

Objectives Sub-Saharan Africa faces a shortage of skilled epidemiologists to prevent, detect, and respond to health threats. Tanzania has implemented one of the first Centers for Disease Control and Prevention Field Epidemiology Training Program (FETP) Intermediate courses in Africa. This course aims to strengthen health workforce capacity in surveillance system assessment, outbreak investigation, and evaluation, prioritizing HIV control. We conducted an outcome evaluation of this new course. Methods We used a pre/post evaluation design using data from 4 cohorts of trainees who took the FETP Intermediate course from 2017 to 2020. We conducted knowledge assessments before and after each cohort and combined those results. Outcomes included knowledge and self-rated competency and trends in integrated disease surveillance and response (IDSR) data. We collected data through tests, field assignments, exit interviews, and data audits. We compared the mean change in pre-/posttest scores using linear regression and 95% CIs. We used content analysis to summarize exit interviews. Results Fifty-three FETP trainees from 10 regions enrolled in the FETP Intermediate course, and 52 (99.0%) completed the course. We found substantial increases in mean knowledge (44.0 to 68.0 points) and self-rated competency (4.14 to 4.43) scores before and after the course. Trainees evaluated 52 surveillance systems and 52 district HIV care programs, and 39 (75.0%) trainees participated in outbreak investigations. From before to after cohort 1, timeliness and completeness of IDSR reports increased from 4.2% to 52.1% and from 27.4% to 76.5%, respectively. Course strengths were quality of instruction, individualized mentoring, and practical skills gained. Challenges were mentor availability, limited time for data analysis practice, and balancing work and field assignments. Conclusions The Tanzania FETP Intermediate course substantially improved trainee knowledge and helped to improve local data quality and reporting. This course is a promising model to strengthen subnational capacity to prevent, detect, and respond to public health threats in Africa.
