The Relationship between Beighton Score and Biomechanical Risk Factors among Adolescent, Female Volleyball Players

ObjectiveTo investigate the relationship between Beighton score and biomechanical risk factors, such as knee valgus, in female, adolescent volleyball players. DesignCross-sectional study. SettingBiomechanics laboratory. Participants25 adolescent, club-level female volleyball athletes (14.5 ± 1.8 years) were tested between 9/2021 – 11/2021. Main outcome measuresParticipants were asked to perform a double-leg vertical jump (DLVJ), a single-leg squat (SLS), and a single-leg drop landing (SLDL). Peak coronal plane angles during the DLVJ, SLS, and SLDL were computed. Spearman correlations were performed to identify significant relationships between Beighton score and biomechanical variables. ResultsPeak knee valgus was found to be moderately correlated to Beighton score during the DLVJ-Land (r = 0.487, p = 0.014), SLDL (r = 0.478, p = 0.016), and SLS (r = 0.439, p = 0.028) tasks. ConclusionsOverall, adolescent volleyball players with higher Beighton scores tended to exhibit a greater peak knee valgus, suggesting that such athletes could benefit from a targeted neuromuscular training or injury prevention program.

Energy Availability in Female Collegiate Beach Volleyball Athletes.

Willingham, BD, Daou, M, VanArsdale, J, Thomas, M, and Saracino, PG. Energy availability in female collegiate beach volleyball athletes. J Strength Cond Res 38(11): 1941-1950, 2024-Low energy availability (LEA) is a present risk for many female athletes. Yet, the literature on LEA is often reliant on single, short-term, snapshots, which may not be reflective of the chronic energy balance surrounding female athletes in sport. Therefore, the purpose of this study was to establish the current prevalence of LEA in female collegiate beach volleyball athletes during the preseason and across the competitive season. One-way repeated measures analysis of variance was used to compare measures of EA (i.e., dietary intake, activity energy expenditure [EE], body composition) and EE (i.e., resting metabolic rate and thermic effect of feeding) at 4 timepoints-once in the preseason (i.e., Fall), and 3 times across the 10-week competitive season in Spring (i.e., week 1, week 5, and week 9). Significance was set at p ≤ 0.05. Although mean EA was in the subclinical zone (i.e., 30-45 kcal·kg FFM-1·d-1) at each timepoint, the prevalence of LEA for individuals was 30.8% in the preseason, 37.5% at week 1, 25.0% at week 5, and 62.5% at week 9. Further, carbohydrate intake was below the recommended range for power athletes at each timepoint, suggesting that female beach volleyball athletes with LEA may benefit from increasing carbohydrate intake. Despite no statistical differences in body mass across the season (p = 0.577), there was a trend for increasing fat-free mass (p = 0.062) as the season progressed. Importantly, LEA is not a team-wide condition but an individual one. Therefore, approaches to mitigate LEA should be individualized.

Fungal Skin Infections in Beach Volleyball Athletes in Greece

Background/Objectives: Fungal infections, commonly referred to as mycoses, are widespread and affect various parts of the body. Common types of fungal skin infections include tinea pedis, tinea unguim, tinea cruris, tinea versicolor, and tinea manuum. Athletes, in particular, are at a higher risk of contracting these infections due to several factors inherent to their training and competitive environments. Methods: This research examined the incidence, anatomical distribution, and seasonal occurrence of fungal skin infections among beach volleyball athletes in Greece. The study cohort consisted of 785 participants, with an average age of 28.4 years. Variables recorded included gender, the seasonal periods during which athletes might be more prone to injuries, and the specific body areas affected by fungal infections. In addition, training-related data such as weekly training frequency, and daily training duration were collected. Results: Incidence rates correlated in relation to gender: male, tinea pedis (p < 0.000), tinea manuum (p < 0.010); number of weekly trainings: tinea pedis (p < 0.000), tinea unguium (p < 0.043), tinea cruris (p < 0.008), tinea versicolor (p < 0.038), tinea manuum (p < 0.043); average hours of daily training: tinea unguium (p < 0.039), tinea manuum (p < 0.039). Conclusions: Athletic activities often involve exposure to warm, moist conditions that promote fungal growth. Locker rooms, showers, and equipment can harbor fungi, spreading infections among athletes. Understanding these infections is essential for effective prevention and management, as they can impact performance and health if untreated. Proper hygiene, antifungal treatments, and public health measures are crucial to reducing the risk in athletic settings.

Postural analysis of adolescent young athletes in different sports branches

The effects of posture on athletic performance have been the focus of attention of many researchers and the importance of body posture in achieving success has become undeniable. This study aimed to perform the postural evaluation of adolescent youth athletes who are trained in basketball, soccer, volleyball, and swimming branches. A total of 88 adolescent athletes (32 boys and 56 girls) with an average age of ±12.37 years, an average height of ±1.58 cm, an average body weight of ±48.2 kg, an average BMI of ±18.19 and an average training age of ±2.06 years from football, volleyball, and swimming branches actively active in Manisa and Bursa provinces participated in the study. Posture analysis of the athletes was performed using the Apecs-AI Posture Evaluation and Correction System® mobile posture application. The data obtained from the athletes were evaluated with the NewYork Posture Assessment Test (NYPD). The data obtained from the study were analyzed using the SPSS 22.0 package program. One-way Analysis of Variance (ANOVA) was used for independent samples. According to the results of the analysis, there was a significant difference between training age and NYPD scores according to branches (p<.05). Significance was found between NYPD and body axis scores in volleyball and soccer athletes (p<.05). There was no difference between NYPD and other variables in swimming and basketball. As a result, it is thought that the effect of the training age variable on posture structures differs specifically according to the branches, and posture is negatively affected as the training age increases in volleyball and soccer players.

The Functional Organization of Corticomotor Neurons Within the Motor Cortex Differs Among Basketball and Volleyball Athletes With Patellar Tendinopathy Compared to Asymptomatic Controls.

Patellar tendinopathy (PT) typically affects jumping-sport athletes with functional impairments frequently observed. Alterations to the functional organization of corticomotor neurons within the motor cortex that project to working muscles are evident in some musculoskeletal conditions and linked to functional impairments. We aimed to determine if functional organization of corticomotor neuron projections differs between athletes with PT and asymptomatic controls, and if organization is associated with neuromuscular control. We used a cross-sectional design, and the setting was Monash Biomedical Imaging. Basketball and volleyball athletes with (n = 8) and without PT (n = 8) completed knee extension and ankle dorsiflexion force matching tasks while undergoing fMRI. We determined functional organization via identification of the location of peak corticomotor neuron activation during respective tasks (expressed in X, Y, and Z coordinates) and calculated force matching accuracy for both tasks to quantify neuromuscular control. We observed significant interactions between group and coordinate plane for functional organization of corticomotor projections to knee extensors (p < 0.001) and ankle dorsiflexors (p = 0.016). Compared to controls, PT group peak corticomotor activation during the knee extension task was 9.6 mm medial (p < 0.001) and 5.2 mm posterior (p = 0.036), and during the ankle dorsiflexion task 8.2 mm inferior (p = 0.024). In the PT group, more posterior Y coordinate peak activation location during the knee extension task was associated with greater task accuracy (r = 0.749, p = 0.034). Functional organization of corticomotor neurons differed in jumping athletes with PT compared to controls. Links between functional organization and neuromuscular control in the PT group suggest organizational differences may be relevant to knee extension neuromuscular control preservation.

Relationships between morphological features and physical performance depend on sex and age groups: a cross-sectional study among Brazilian beach volleyball players.

Understanding the evolution of morphological features and their relationship with physical performance may assist coaches and institutions in developing the next generation of beach volleyball (BV) athletes for senior-level competition. Thus, this study analyzed the morphological features of Brazilian BV athletes by sex among age groups, and their relationship with physical performance. A cross-sectional design was used to evaluate Brazilian BV players of both sexes in the U15 (11-14 years old, N.=21), U18 (15-17 years old, N.=21) and Senior (≥18 years old, N.=19) categories. The players underwent a series of kinanthropometric tests, including morphological (anthropometry, body composition and somatotype), neuromuscular (flexibility, handgrip strength, vertical jump [VJ], agility, and 5-m and 10-m maximum-speed sprints), and metabolic (VO<inf>2max</inf>) measurements. Welch analysis of variance (ANOVA) was used to compare the categories and the relationship between morphological and physical performance features was analyzed using Pearson's coefficient (r). Significant differences were found among the categories for female (body mass, skeletal muscle mass, hamstring flexibility, handgrip strength [HGS]) and male (body mass, height, BMI, skeletal muscle mass, flexibility, HGS, vertical jump, agility, maximum-speed sprints, and VO<inf>2max</inf>) players. Moreover, moderate, and strong correlations were identified between morphological features and physical performance (-0.90≤r≤0.89). The morphological and physical performance features of BV athletes varied among the U15, U18, and Senior categories, as expected due to their physical training process. Additionally, there are several morphological features that are correlated with physical performance, but the magnitude seems to depend on sex and category.

Effects of Plyometric Exercise of Adolescent Male Volleyball Athletes: A Systemic Review

By looking at previous literature, this study aimed to analyze the construct of plyometric exercise variation. Comprehensive methods are used for these articles, such as searching for articles in database research journals. Semantic, Scopus, Scholar, and Crossref are the data sources for this database. The variety of plyometric exercises and vertical jump skills are the main themes. Fifty-one articles were verified, and then 12 articles were evaluated based on objectives, topics, sample size, research protocols, and results. Plyometric exercises are exercises in which the movements are explosive and, besides being practical, also train muscle strength, muscular endurance, flexibility, and agility. The purpose of volleyball training is so that players can acquire good basic techniques, strengthen physical strength, and develop interests and talents. To improve jumping ability, various exercises are performed from the beginner level. Therefore, the ability to jump and jump is essential for the volleyball game. The novelty in this study is the using a form of plyometric exercise that is varied according to the characteristics of athletes aged 14-17 years that have never previously been applied in volleyball clubs, which is the focus in this study of plyometric exercise variation methods, namely plyometric squat jump, skipping and hurdle hopping. The intensity of the exercise will be adjusted to the characteristics, and physiological development of male athletes aged 14-17 years.

The Prevalence of Spondylolysis and the Diagnostic Sensitivity of Radiography in Adolescent Low Back Pain

ABSTRACT Introduction The aims of this retrospective chart review were to determine the prevalence of radiographically positive spondylolysis based on the historical “gold standard” of single photon emission computed tomography (SPECT) and to evaluate the sensitivity of radiographs in detecting spondylolysis relative to SPECT scans in adolescent athletes presenting with low back pain (LBP). Our secondary outcome measure included an assessment of the variable prevalence of spondylolysis in different athletic subpopulations. Methods Radiographs and SPECT scans for patients with LBP were reviewed for the presence of spondylolysis. The sensitivity and specificity of two-view and four-view radiographs compared to SPECT scans were calculated, and the associations between diagnosis of spondylolysis and age, gender, and sport were determined. Results Nine hundred ninety-nine adolescent patients presented with LBP; 405 SPECT scans were performed. Of those, 141 (35%) SPECT scans were positive for spondylolysis. The prevalence rate for spondylolysis in this population who presented with LBP was 14%. Compared to SPECT scans, two-view radiographs were more specific (92.93%) and had a higher negative likelihood ratio (0.81) for spondylolysis than four-view radiographs. Boys were more likely to have a positive SPECT scan compared to girls (adjusted odds ratio, 6.07; 95% confidence interval, 3.00–12.26). Younger age was significantly associated with a spondylolysis diagnosis (adjusted odds ratio, 1.24; 95% confidence interval, 1.09–1.41). Lacrosse, soccer, softball, and volleyball athletes had a significantly lower risk of spondylolysis diagnosis compared to football and gymnastics athletes. Conclusions This research contributes to data regarding the prevalence of spondylolysis in symptomatic, adolescent athletes. Two-view radiographs were more useful screening tests for spondylolysis than four-view radiographs. Younger athletes, boys, and those who participate in certain sports were more likely to have evidence of spondylolysis on SPECT scans.
