RESUMO
BACKGROUND: Facet tropism (FT) can be defined as the angular difference between the orientation of the right and left facet joints in axial or sagittal planes. Most studies discuss about the relationship with lumbar disc hernia and facet joint angle. However, little is known about the association of facet tropism with disc herniation in the cervical spine in multisports athletes. In this study, We aimed to investigate the relationship between cervical facet tropism and disc hernia in athletes of different branches between the ages of 20-40 from the cervical MR images of the cases. METHODS: This is a retrospective study performed on athletes who applied our hospital between January 2014-2019 with neck pain and have MR imaging of the cervical spine. Cervical MR images of the patients were evaluated by an experienced radiologist from the hospital system database and archives. 79 cases (52 men and 27 women) were included in the study. RESULTS: No statistically significant difference was found between the facet joint angles of both groups at all levels (pË0.05). Only left C6-7 disc angles of CDH group were measured as 92.99° ± 10.770 (620-1130) and 88.58° ± 7.65° (67°-110°) for the normal group and this difference was found statistically significant (p = 0.007). CONCLUSION: In this study, we did not predict that cervical facet tropism may be a factor associated with cervical disc hernia in young athletes with CDH.

PURPOSE: Glenoid bone loss contributes to recurrent instability after arthroscopic Bankart repair alone. With significant glenoid bone loss, better results have been reported after arthroscopic Bankart repair with glenoid arc reconstruction. However, no reports compare augmentation using bone graft with non-augmentation for glenoid bone loss. The purpose of this study was to assess clinical results of an arthroscopic Bankart repair with or without arthroscopic bone graft augmentation. It was hypothesized that such bone graft augmentation would restore shoulder stability, and lead to excellent outcomes. METHODS: Of 552 patients treated for anterior glenohumeral instability with arthroscopic Bankart repair, 68 met this study's inclusion criteria of glenoid bone loss over 20% and follow-up of at least 2 years. Patients were divided into 2 groups based on whether with bone graft augmentation for glenoid bone loss [Group A: n = 35, median age; 21 years (range 13-72 years)], or not (Group B: n = 33, median age; 21 years (range 13-50 years)]. For grafting, either autologous iliac bone or artificial bone made of hydroxyapatite was used. Rowe score, recurrence rate, and return to sport were used to assess the results. RESULTS: Mean Rowe score was 95.0 (SD 10.6) in Group A and 69.7 (SD 27.2) in Group B (p < 0.05). The recurrence rate was 2.9% (1/36) in Group A and 48.5% (16/33) in Group B (p < 0.05). Regarding contact/collision athletes, 24 were contained in Group A and 22 in Group B. Of the patients with recurrence in Group B, 13 (59.1%) were contact/collision athletes. Finally, 50% of the contact/collision sports athletes for both groups returned to their sports at the same as pre-injury level. Of the 11 patients who returned to the same level of contact/collision sports in Group B, seven returned with residual instability. Nine athletes in Group A and 3 in Group B quit their sports for personal or social reasons. CONCLUSIONS: Bone graft augmentation was beneficial when used with Arthroscopic Bankart repair for recurrent anterior shoulder instability with glenoid bone loss. Especially, for recurrent anterior shoulder instability with glenoid bone loss in contact/collision sports athletes, bone graft augmentation should be strongly considered as beneficial. LEVEL OF EVIDENCE: Level IV.

PURPOSE: Acute meniscus repair in young athletes is always a challenge due to the long rehabilitation process and time to return to sport (RTS). The purpose was to investigate signal alterations in short-term follow-up after acute meniscus repair on specific magnetic resonance imaging (MRI) scan sequences. It was hypothesized that (1) MRI signal changes over the first postoperative healing phase and represent a continuous healing process and (2) meniscus healing properties correlates with clinical outcomes and RTS. METHODS: Young athletes with traumatic meniscus lesion and arthroscopic meniscus repair within 6 weeks and available preoperative MRI were enrolled. Clinical examination, outcome scores (IKDC, KOOS, Lysholm Score, Tegner activity score) and RTS were surveyed preoperatively and 6 and 12 weeks and 6 months after surgery. Radiological follow-up examinations were performed 2, 4, 6, 12 weeks and 6 months after operation using a 3T-MRI. Evaluation was based on ISAKOS meniscus classification system, meniscus healing were classified according to Henning's criteria. RESULTS: At final follow-up (FU) 30 patients (28 month, 2 week) with a total of 35 meniscus tears (19 medial, 16 lateral) were included. Clinical scores improved significantly after surgery: IKDC Score (preOP: 39.4 ± 18.5, final FU: 78.8 ± 15.3) KOOS (preOP: 45.7 ± 22.1, final FU: 82.7 ± 12.5) and Lysholm Score (preOP: 42.8 ± 23.7, final FU: 84.4 ± 13.8) (p < 0.01). Tegner activity score showed a steadily increase to 4 (range 3-9) at 6 months but did not reached the pre-injury level of 6 (range 3-9). RTS rate was 100% whereof 44.8% reached their pre-injury level. MRI examination revealed a continuous healing process and menisci were classified as 55.9% healed, 35.3% partially healed and 8.8% non-healed at final FU. CONCLUSION: This study showed that MRI signal alterations of the meniscus steadily occur within the first 6 months postoperatively. MRI reveals an ongoing healing process at final FU that have to be carefully considered when RTS is discussed with high demanding patients. However, young athletes provide good clinical results and RTS rate even though MRI alterations are still present. LEVEL OF EVIDENCE: Therapeutic study, prospective case series, Level IV.

A kettlebell is a weight made of cast iron shaped like a ball with a handle. Commercial kettlebells are offered in capacities that vary from 3 pounds to 100 pounds (or more). The kettlebell has a variety of possible clinical applications, including dynamic flexibility exercises and power training. Players' efficacy during the game can be improved by developing their strongest potential prior to exercising and efficiently converting that strength to power as the event draws near. Strengthening has been recommended as an effective means to avoid injuries, build muscle strength, and enhance one's health in relation to performance in the game. This type of training focuses on the hip, thigh, core, and abdominal muscles to help with appropriate lower-limb alignment and the recruitment of muscle patterns. Kettlebell training is a flexible and useful strategy for improving players' performance in a variety of sports. It adds value to athlete training programs by enhancing strength, power, endurance, explosive power, and postural coordination.
RESUMO
Introduction: Team sports athletes need excellent perceptual-cognitive skills, particularly executive functions (EF) to strategically perform on the field. The transfer effect of cognitive training might be accomplished by the inclusion of cognitive stimuli into a physically active environment as these couplings are required in real game situations. A training approach that combines both components is exergaming. The primary objective of this study was to gain preliminary insights into the effects of exergaming on cognitive-motor functions in young team sports athletes. The secondary objective was to investigate participants' training experience and well-being over time. Methods: Participants were assigned to the intervention or control group. In the intervention group, participants trained with the ExerCube-a mixed reality exergame. The training was planned for 10 weeks (two sessions per week à 25â min) but had to be shortened by 2 weeks due to COVID-19 restrictions. The control group had no additional training. Outcomes included a computer-based alertness test and a cognitive-motor test battery to assess different EF (flexibility, divided attention, and inhibition) via a FitLight Trainer setup. Results: Twenty-four athletes [mean age (±SD) 15.0 ± 0.7 years], evenly split into the intervention group (N = 12; male N = 6; female N = 6; 14.7 ± 0.5 years) and the control group (N = 12; male N = 7; female N = 5; 15.3 ± 0.8 years), participated in the study. Participants in the intervention group performed on average 9.4 ± 3.3 training sessions over 8 weeks. Significant time x group interaction effects were evident for the cognitive-motor sub-tests flexibility (F = 12.176, p < 0.001, d = 1.488) and divided attention for auditive stimuli (F = 9.776, p = 0.002, d = 1.404) in favour of the intervention group. For the alertness test, a medium effect size (time x group interaction) was seen for the variability of the reaction time (F = 2.196, p = 0.138, d = 0.632) in favour of the intervention group. Training experience and well-being were consistently at medium to high levels. Conclusion: The ExerCube training yielded positive effects on concentration, flexibility, and divided attention indicating that exergaming can be an innovative training approach for team sports athletes.
RESUMO
This study aimed to investigate the effects of Judo athletes' psychological function on sports coping skills through self-management: the moderated mediating effect of tension. A total of 124 participants (66 males and 58 females) were included, comprising high school students, college students, and judo team players (age 16 to 30, 20.51 ± 3.17) in the Republic of Korea. The psychological function was measured using the Profile of Mood Test, Athletes' Self-Management Questionnaire, and Athletic Coping Skills Inventory-28. The results of the analysis of the moderating effect of the athlete's self-management behavior showed that tension had a moderating effect on the relationship between the athlete's self-management behavior and sports coping skills. The mediating effect analysis revealed a mediating effect of self-management behavior on the relationship between player vitality and sports coping skills. It was also confirmed that tension had a moderating effect on athletes' self-management behavior and sports coping skills. Therefore, it was confirmed that the higher the self-management, the more moderated the mediating effect on sports coping skills. In conclusion, it was confirmed that psychological function affects sports coping skills, and thereby, the mediating effect of the athlete's self-management behavior is regulated by tension. In future research, it will be necessary to study the sports coping ability and performance of judo athletes according to tension control.

OBJECTIVES: To evaluate Maximum Voluntary Contraction (MVC) of the Pelvic Floor Muscles (PFM) in sportswomen, to observe the urinary symptoms and their impact on the Quality of Life (QoL). DESIGN: Observational cross-sectional study. SETTING: Gyms and teams in the North of Portugal. PARTICIPANTS: Sportswomen (n = 197). MAIN OUTCOME MEASURES: The measurement was performed using a manometer. The sportswomen were instructed to perform 3 MVC of the perineum, held for 3 s. The Kings Health Questionnaire (KHQ) was used to evaluate urinary symptoms and the QoL of the sportswomen. RESULTS: Age significantly influenced (p < 0.05) the QoL in all domains. An increase in BMI was also significantly associated with a decrease in the QoL. MVC values had a highly significant effect on the overall QoL and all domains, including a reduction in urinary symptoms. The weekly time of physical activity was associated with a better QoL in symptomatology. The practice of high-impact activities decreased the QoL (compared to low-impact activities). The vaginal resting pressure values ranged from 1.60 to 59.80 (24.34 ± 11.00). CONCLUSIONS: Age, BMI and high-impact sports appear to be the leading factors that promote the onset of SUI, which in turn decrease the QoL in sportswomen. There was a positive association between MVC and weekly time of physical activity in the QoL.

PURPOSE: The purpose of our study was to determine the effectiveness of carbohydrate loading by additional carbohydrate supplements for 7 days after prolonged interval exercise on exercise performance and energy metabolism during submaximal exercise in team-sports athletes. METHODS: Twenty male team-sports athletes (14 soccer and 6 rugby players) volunteered to participate in the study and were equally divided into the experimental group (EXP, n=10) performing additional carbohydrate supplementation for 7 days after prolonged interval exercise until blood glucose level reaches 50 mg/dL or less and the control group (CON, n=10). Then, maximal oxygen consumption (VO2max) and minute ventilation (VE), oxygen consumption (VO2), carbon dioxide excretion (VCO2), respiratory exchange ratio (RER), blood glucose level, and blood lactate level were measured in all team-sports players during submaximal exercise corresponding to 70% VO2max before and after intervention. RESULTS: There was no significant interaction in all parameters, but team-sports players in the EXP presented more improved VO2max (CON vs EXP = vs 5.3% vs 6.3%), VE (CON vs EXP = vs 3.8% vs 6.6%), VO2 (CON vs EXP = vs 8.5% vs 9.9%), VCO2 (CON vs EXP = vs 2.8% vs 4.0%), blood glucose level (CON vs EXP = vs -12.9% vs -7.6%), and blood lactate level (CON vs EXP = -18.2% vs -25%) compared to those in the CON. CONCLUSION: These findings showed that additional carbohydrate supplementation conducted in our study is not effective in exercise performance and energy metabolism during submaximal exercise.
RESUMO
Exercise training has been shown not only to influence physical fitness positively but also cognition in healthy and impaired populations. However, some particular exercise types, even though comparable based on physical efforts, have distinct cognitive and sensorimotor features. In this study, the effects of different types of exercise, such as fast ball sports and dance training, on brain electrical activity were investigated. Electroencephalography (EEG) scans were recorded in professional dancer, professional fast ball sports athlete (FBSA) and healthy control volunteer groups consisting of twelve subjects each. In FBSA, power of delta and theta frequency activities of EEG was significantly higher than those of the dancers and the controls. Conversely, dancers had significantly higher amplitudes in alpha and beta bands compared to FBSA and significantly higher amplitudes in the alpha band in comparison with controls. The results suggest that cognitive features of physical training can be reflected in resting brain electrical oscillations. The differences in resting brain electrical oscillations between the dancers and the FBSA can be the result of innate network differences determining the talents and/or plastic changes induced by physical training.
RESUMO
Objective: to verify the effectiveness of the pelvic floor muscles rehabilitation program (PFMRP) in female volleyball athletes, analyzing the amount and frequency of urinary leakage. Methods: experimental study. The sample consisted of 32 female athletes from Famalicão Athletic Volleyball Club (Portugal). The athletes were selected by convenience and distributed randomly into two groups: experimental group (EG = 16 athletes) and the control group (CG = 16 athletes). The EG underwent PFMRP for three months. The PFMRP was the awareness and identification of the pelvic floor muscles (PFM), pre-timed PFM contraction prior to occasions of increased intra-abdominal pressure, and 30 daily contractions of MPP at home. The CG had only access to the pamphlet. The assessment instruments included the questionnaires, the Pad Test (amount of urinary leakage) and frequency record of urinary leakage (7-day diary) before and after PFMRP. Results: the amount of urine leakage decreased in 45.5% of athletes under PFMRP intervention, and in 4.9% of athletes in CG, with statistical differences between the groups (p < 0.001). The reduction in the frequency of urinary leakage was 14.3% in EG, and 0.05% in CG, a statistically significant difference between the groups (p < 0.001). Conclusion: PFMRP in this study was effective to reduce stress urinary incontinence in female volleyball athletes. The program allowed significant improvement of symptoms of quantity and frequency of urinary leakage. .
Objetivo: verificar a eficácia do programa de reeducação dos músculos do pavimento pélvico (PRMPP) em atletas femininas de voleibol, analisando a quantidade e a frequência das perdas urinárias. Métodos: estudo experimental. A amostra foi constituída por 32 atletas do sexo feminino do Atlético Voleibol Clube de Famalicão (Portugal). As atletas foram selecionadas por conveniência e distribuídas aleatoriamente em dois grupos: o grupo experimental (GE = 16 atletas) e o grupo-controle (GC = 16 atletas). O GE foi submetido ao PRMPP durante 3 meses; o programa consistiu na conscientização e identificação dos músculos do pavimento pélvico (MPP), na pré-contração dos MPP ao aumento da pressão intra-abdominal, e em 30 contrações diárias dos MPP no domicílio. O GC teve acesso unicamente ao panfleto. Os instrumentos de avaliação englobaram os questionários, o pad-test (quantidade de perda urinária) e o PRMPP. Resultados: a quantidade de perda urinária diminuiu 45,5% no GE, com intervenção do PRMPP, e 4,9% nas atletas do GC, verificando-se diferenças estatisticamente significativas entre os grupos (p<0,001). Na frequência das perdas urinárias, a redução foi de 14,3% no GE e de 0,05% no GC, verificando-se diferenças estatisticamente significativas entre os grupos (p<0,001). Conclusão: o PRMPP, nessa amostra, foi eficaz na incontinência urinária de esforço em atletas do sexo feminino de voleibol, pois permitiu melhorar significativamente os sintomas de quantidade e frequência das perdas urinárias. .
