The observed dynamic knee valgus and the limited dynamic balance described in the literature are modifiable risk factors for injuries in athletes. Therefore, identification and appropriate prevention are crucial in managing the development of young athletes. The aim of the study was to assess the effectiveness of three exercises strengthening the muscles: gluteal medius, popliteal and tibialis posterior to reduce dynamic knee valgus and improve the dynamic balance of the lower limbs in young football players with poor knee control. A total of 134 footballers were assessed for eligibility, and finally 45 participants (age 12–15) met the inclusion criteria. Participants were assessed with 2D video kinematic analysis during single-leg squats to assess the knee valgus angles and the dynamic balance (Y-Balance Test). No significant interactions between groups (Control and Exercise) and time (baseline and after 6 week) were noted for dynamic valgus for the left and right knee (p > 0.05). For the dynamic balance, there were statistically significant results, but not clinically relevant for anterior, posteromedial, and composite direction for the right lower limbs and for the anterior direction for left lower limbs in the exercise group. However, there were no significant differences (p > 0.05) in all of the YBT scores for both lower limbs between groups. This study demonstrated that there were no statistically significant differences in dynamic knee valgus angles and dynamic balance values after 6 weeks of exercise program in young footballers with poor knee control. Future randomized trials should focus on more comprehensive exercises, where possible using biofeedback methods to improve knee kinematics.

Dynamic Valgus

Abstract Background Participation of children and youth in sporting activities, among others in training and football competitions, is an optimistic manifestation of activation in the current trend of computerization. Unfortunately, this is also often associated with musculoskeletal injuries. An example is the association of dynamic valgus and disturbed dynamic balance with lower limb injuries. The main purpose of the studies is to determine the impact of three strengthening exercises on the parameters of dynamic knee valgus and balance of lower limbs. The secondary objectives are to investigate the dominant influence and the length of lower limb on the valgus values and to determine risk of injury to young football players. Methods 134 young footballers training at the Arka Gdynia SI club were invited to first stage of the research in order to examine anthropometric features and kinematics of the lower limb. Single Leg Squat Test was used, which was recorded. The samples were analyzed video to determine exact knee angle of valgus. During the second stage, to which players with valgus knee were qualified (≥15˚), the Y-Balance Test was additionally used. Intervention group underwent an exercise program to strengthen gluteus medius, popliteal and tibialis posterior muscles for 6 weeks to repeat tests in the third stage. Results Statistical methods used at the assumed level of significance allow to conclude that there are no differences in results of dynamic valgus (≥15˚) and dynamic balance between the intervention group and control group during the 6 week period between stages. In addition, there were results confirming the lack of influence of length and dominant lower limb on valgus. Results of composite direction in the Y-Balance Test test determine the low risk of injury in both intervention and control groups. Conclusions Intervention did not affect the dynamic valgus and knee balance in young football players. Both the length and the dominant limb did not affect the results. The "low risk" occurrence of injuries among the examined participants with valgus knee due to the values of dynamic balance was determined.

AbstractPurpose. To verify the influence of neural mobilization (NM) applied to the lower limbs on functional performance and dynamic balance in asymptomatic individuals. Methods. The total of 30 asymptomatic participants (15 women and 15 men; age, 30.1 ± 6.7 years; height, 1.70 ± 0.1 m; body mass, 73.1 ± 13.4 kg) were enrolled in this cross-over randomized controlled trial. The participants received NM of the femoral, sciatic, and tibial nerves, as well as static stretching (SS) of the following muscles: hamstring, lumbar, piriformis, hip adductors, hip flexors, quadriceps, and triceps surae. The order of applying NM and SS was randomly decided and the interventions were performed at least 48 hours apart. Functional performance was measured by performance in vertical jump (VJ) and dynamic balance was measured with the Star Excursion Balance Test (SEBT). Results. There were no differences between NM and SS for height (cm) in VJ (p = 0.16) or in the distance reached (%) in the SEBT, normalized by lower limb length (dominant limb: anterior, p = 0.35; posterolateral, p = 0.69; posteromedial, p = 0.50 / non-dominant limb: anterior, p = 0.68; posterolateral, p = 1.00; posteromedial, p = 0.77). Conclusions. NM did not exert any influence on functional performance or dynamic balance. Thereby, having no positive or negative impact on performance, NM can be used at any time of treatment.

Proximal neuromuscular alterations are hypothesized to contribute to the patient- and disease-oriented deficits observed in CAI individuals. The objective was to compare the efficacy of two 4-week intervention programs with or without proximal joint exercises. Twenty-three individuals with CAI completed this single-blinded randomized controlled trial. Outcome measures included the Star Excursion Balance Test (SEBT) and the Foot and Ankle Ability Measure (FAAM). A time main effect was observed for the FAAM-ADL (p = .013), FAAM-Sport (p = .012), and posteromedial (p = .04) and posterolateral (p = .003) SEBT reach directions. No group main effect or time by group interaction was found. Four weeks of supervised rehabilitation improved self-reported function and dynamic balance in people with CAI.

Objective:To assess and compare the effects of 6 mo of Pilates and calisthenics on multijoint coordination and proprioception of the lower limbs at the 3rd and 6th mo of training.Design:Randomized, controlled, assessor-blinded, repeated-measures.Setting:University research laboratory.Participants and Intervention:Healthy, sedentary, female participants age 25–50 y were recruited and randomly divided into 3 groups: a calisthenic exercise group (n = 34, mean age ± SD 40 ± 8 y, body-mass index [BMI] 31.04 ± 4.83 kg/m2), a Pilates exercise group (n = 32, mean age ± SD 37 ± 8 y, BMI 31.04 ± 4.83 kg/m2), and a control group (n = 41, mean age ± SD 41 ± 7 y, BMI 27.09 ± 4.77 kg/m2). The calisthenics and Pilates groups underwent related training programs for 6 mo, while the controls had no specific training.Main Outcome Measures:Coordination and proprioception of the lower extremities with concentric and eccentric performances in the closed kinetic chain assessed with the monitored rehab functional squat system at baseline and at the 3rd and 6th mo of training.Results:For the within-group comparison, coordinative concentric and eccentric deviation values were significantly decreased for both dominant and nondominant lower limbs at pretraining and at the 3rd and 6th mo posttraining in the calisthenics group (P < .05). In contrast, there was no improvement in the Pilates group throughout the training. However, for comparisons between groups, the baseline values of coordinative concentric and eccentric deviations were different in the calisthenics group than in Pilates and the controls (P < .05). There were no differences in the proprioception values of either visible or nonvisible movement in any group throughout the training (P > .05).Conclusions:It seems that calisthenic exercises are more likely to improve coordination of the lower extremity after 3 and 6 mo of training than Pilates exercises. Calisthenic exercises may be useful for individuals who require improved coordination.

Research background. Aging constantly manifests itself not only in physiological changes, but also in cognitive ones. Exercise programs for elderly have been created aiming at avoiding risk of falling, but there is little known about changes in cognitive functions under the effect of exercise. The aim was to evaluate the effect of water-based and land-based exercises on balance and cognitive functions in elderly women and men. Methods. The dynamic balance of study participants (n = 32) was evaluated using Timed Up & Go Test, the static balance was evaluated with a 4-position Static Balance Test and the cognitive functions were evaluated with Six-Item Cognitive Impairment Test, the Cognitive Failures Questionnaire and the Trail Making Test. The participants were randomly divided in two groups: water exercise and land-based exercise. Results. After 8 weeks of exercise in water and on land, static and dynamic balance and cognitive functions improved in both groups (p < 0.05), no statistically signifcant difference was found between the groups except for the trail making test, which was performed more quickly by subjects who attended exercise in water. After the exercise program, the men’s dynamic and static balance (while standing in the tandem position) were better than women’s, but women’s standing on one leg position was better than that of men’s (p < 0.05). Conclusion. There were no statistically signifcant differences in cognitive function between men and women after intervention. After both exercise programs, dynamic and static balance (in the tandem position) in men were better (p < 0.05) than those in women, standing on one leg but women’s position was statistically signifcantly better than that of men’s.Keywords: exercise program in water and land-based, static and dynamic balance, cognitive functions.

Abstract Background and Aims Percutaneous needle electrolysis has shown to be effective for the treatment of chronic tendinopathies, however, the scientific evidence available regarding acute muscle lesions is scarce. Lesions to the hamstrings caused by indirect mechanisms represent the most common muscle lesion in football (its incidence increases each year) with a high rate of recurrence. The aim was to evaluate whether the application of percutaneous needle electrolysis and a program of functional exercise decreases the times for return to competition after an injury to the hamstrings in athletes, and to compare performance data of subjects during competition before and after the injury. Methods A case series. Two professional football players, belonging to a first league team in Spain with a grade 2 lesion in the semitendinosus muscle on the proximal level. The affected muscle structure was assessed using ultrasound (Logiq GE E9, probe ML6–12) and functionality was evaluated based on data of the Global Positioning System (GPS), comparing the data obtained during the process of re-adaptation with data prior to the lesion. Percutaneous needle electrolysis was performed under ultrasound guidance at 48 hours after the injury following the protocol defined by Valera & Minaya (2:3:5). The indoor recovery of players began 24 hours after the percutaneous needle electrolysis. Initially, the exercise program included activities of mobility and controlled loading. Thereafter, the players completed their readaptation program in the training field with exercises of progressive complexity and intensity (biomechanical patterns and neuromuscular control of the central zone and the lower limbs, sprint). Results Player A returned to competition in 16 days, player B returned in 14 days. No adverse effects were identified during or after the percutaneous needle electrolysis technique. The players only missed one competition game and the process of readaptation allowed them to return to play registering parameters which were similar to the values prior to the lesion, and maintaining the performance during the four matches following the intervention protocol. The players were followed up to eight months after the injury and neither player suffered a relapse during this period, which indicates the complete recovery of the injured muscle both on a structural and functional level. Conclusions The combined treatment using percutaneous needle electrolysis and a functional exercise program reduces the time for return to competition after a grade 2 muscle lesion in the hamstrings, with a level of performance that is similar to prior to the lesion, without relapses, in an 8 month follow up period. The criteria we use to determine when a player can return to train with the team and compete after an acute muscle injury are: the time that has passed since the lesion, structural changes and the ability to perform tasks.

Perimenopausal Women

We assessed the effects of a 16-week primary-care-based exercise program on body composition in perimenopausal women. The women (n = 150) were randomized into control (n = 75) or exercise (n = 75) groups. Exercise was provided in a 16-week (60 min/session, 3 days/week) concurrent program. Body composition was measured using dual-energy X-ray absorptiometry. These are secondary analyses of the FLAMENCO Project (Clinical Trials Reference NCT02358109). In the intention-to-treat analyses, the control group showed no changes in body mass index (BMI) between post- and pre-test, whereas the exercise group showed a 0.75 kg/m2 decrease in BMI (95% CI: −1.29 to −0.22; p = 0.006). Gynoid and android fat mass in control group decreased by 98.3 g and 46.1 g after the 16 weeks, whereas they decreased by 213 g and 139 g in the exercise group, respectively (95% CI: −209 to −3.86; p = 0.042 and 95% CI: −164 to −26.9; p = 0.007, respectively). The control group decreased their pelvis bone mineral content by 2.85 g in the post-test compared with the pre-test, whereas the exercise group increased it by 1.13 g (95% CI: 0.93 to 7.81; p = 0.013). Per-protocol analyses showed similar results. These analyses suggest that the exercise intervention decreased fat depositions and BMI. Exercise might improve bone mineral content in specific areas such as the pelvis.

Hippocampal Structure

Interventional studies suggest that changes in physical fitness affect brain function and structure. We studied the influence of high intensity physical exercise on hippocampal volume and metabolism in 17 young healthy male adults during a 6-week exercise program compared with matched controls. We further aimed to relate these changes to hypothesized changes in exercised-induced brain-derived neurotrophic factor (BDNF), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF-α). We show profound improvement of physical fitness in most subjects and a positive correlation between the degree of fitness improvement and increased BDNF levels. We unexpectedly observed an average volume decrease of about 2%, which was restricted to right hippocampal subfields CA2/3, subiculum, and dentate gyrus and which correlated with fitness improvement and increased BDNF levels negatively. This result indicates that mainly those subjects who did not benefit from the exercise program show decreased hippocampal volume, reduced BDNF levels, and increased TNF-α concentrations. While spectroscopy results do not indicate any neuronal loss (unchanged N-acetylaspartate levels) decreased glutamate-glutamine levels were observed in the right anterior hippocampus in the exercise group only. Responder characteristics need to be studied in more detail. Our results point to an important role of the inflammatory response after exercise on changes in hippocampal structure.

Background: The REVIVE randomized controlled trial (RCT) investigated the effectiveness of an individually tailored (personalized) exercise program for patients discharged from hospital after critical illness. By including qualitative methods, we aimed to explore patients’ perceptions of engaging in the exercise program. Methods: Patients were recruited from general intensive care units in 6 hospitals in Northern Ireland. Patients allocated to the exercise intervention group were invited to participate in this qualitative study. Independent semistructured interviews were conducted at 6 months after randomization. Interviews were audio-recorded, transcribed, and content analysis used to explore themes arising from the data. Results: Of 30 patients allocated to the exercise group, 21 completed the interviews. Patients provided insight into the physical and mental sequelae they experienced following critical illness. There was a strong sense of patients’ need for the exercise program and its importance for their recovery following discharge home. Key facilitators of the intervention included supervision, tailoring of the exercises to personal needs, and the exercise manual. Barriers included poor mental health, existing physical limitations, and lack of motivation. Patients’ views of outcome measures in the REVIVE RCT varied. Many patients were unsure about what would be the best way of measuring how the program affected their health. Conclusions: This qualitative study adds an important perspective on patients’ attitude to an exercise intervention following recovery from critical illness, and provides insight into the potential facilitators and barriers to delivery of the program and how programs should be evolved for future trials.
