Background: Few studies have investigated the effects of adopting a specific and prolonged posture on cyclists. This study aimed to evaluate the upright spine in a sample of recreational cyclists and compare it with a sample of non-cyclists, though still athletes, through a 3D scanning method. Methods: Forty-eight participants were enrolled in this observational study. The sample consisted of 25 cyclists for the cycling group and 23 non-cyclist athletes for the control group. The Spine3D device (Sensor Medica, Guidonia Montecelio, Rome, Italy) was used to evaluate the spine of the participants in both groups. Results: The results showed significantly greater spine inclination in the cycling group compared to the control group (p < 0.01). Furthermore, there was a significant decrease in lumbar lordosis in the cycling group compared to the control group (p < 0.01). Conclusions: This case–control study raises the possibility that the onset of lower back pain in cyclists may be due to a reduction in lumbar lordosis. Furthermore, this study demonstrated that the Spine3D device can be used in sports to monitor the spine of athletes to prevent and reduce musculoskeletal deficits.

Background: The ease of administration of the Cumberland Ankle Instability Tool (CAIT) could represent a methodology for periodically evaluating athletes, preventing ankle instability injuries. This study aimed to achieve three objectives: (a) to evaluate the applicability of the CAIT scale in volleyball; (b) to explore whether ankle instability presents a greater risk in lower-level volleyball categories and whether elite athletes demonstrate an ability to mitigate this risk; and (c) to identify potential predictors of ankle instability. Methods: Eighty female volleyball players participated in this cross-sectional observational study. The CAIT was administered to evaluate the athletes belonging to some teams in Series A, B, and C. Results: The Spearman’s ranks correlation coefficient showed significant correlations between CAIT items. Additionally, the Cronbach’s α showed a high internal consistency. Our results showed a significant difference between athletes who reported pain and those who did not (p < 0.001). The multiple linear regression model analysis showed that pain was a predictor of ankle instability (p < 0.001). Conclusions: Our findings suggest that the CAIT can be used to evaluate ankle stability in volleyball players. This scale could represent a valuable tool for implementing specific intervention programs to prevent ankle injuries in athletes.

(1) Background: Ankle joint range of motion is recognized as abnormal in individuals with ankle sprains and Chronic ankle instability (CAI), especially in the dorsiflexion movement. This research investigated the test–retest and inter-rater reliability of the Motustech Beyond IMU for dorsiflexion movement following only one hour of rater training and familiarization. (2) Methods: In total, 62 subjects were evaluated for the inter-rater reliability and test–retest with a one-week interval. The intraclass correlation coefficient (ICC), along with the Concordance Correlation Coefficient (CCC), was determined for each test of reliability. Standard error of measurement, coefficients of variation, limits of agreement (LoA) and minimal detectable change (MDC) were used for the measurement error analysis. (3) Results: Test–retest reliability was ranked excellent (ICC = 0.949) and very high (CCC = 0.897) for both ankle dorsiflexion measurements. On the other hand, Inter-Rater reliability was evaluated as good (ICC = 0.881–0.906) and very high (CCC = 0.783–0.811). However, the measurement error analysis showed poor absolute agreement (LoA), indicating that the resulting measurement variability is considered clinically unacceptable for high-precision applications. (4) Conclusions: Beyond Inertial demonstrated excellent test–retest reliability for ankle dorsiflexion movements, although measurement error analysis showed considerable absolute error. Consequently, it may be considered a reliable tool for single-rater monitoring of ankle dorsiflexion ROM in non-clinical settings such as general physical activity and amateur sports. Future research should investigate its potential role in injury prevention contexts.

Background/Objectives: The recent discovery of the importance of gut microbiota has enhanced our understanding of several issues related to energy metabolism, immune systems, and post-exercise recovery, which could have an impact on sports performance. Probiotics are used as sports supplements and have recently been proposed to be effective in reducing the incidence of gastrointestinal and respiratory infections during training and competition. This scoping review aimed to evaluate the gut microbiota composition of competitive cyclists and investigate the effect of probiotic administration in this sports population. Methods: A literature review was conducted using the following databases: PubMed/Medline, Web of Science, and Scopus, and all studies until 1 November 2025 were considered. After dual-reviewer screening, data were charted to identify the composition of gut microbiota and the effects of probiotics on these types of athletes. Results: After all the study identification phases, eleven studies were selected. Seven studies evaluated the composition of the gut microbiota, while four randomized controlled trials evaluated probiotic intake. The results indicate an abundance of Prevotella distinct for this type of athlete, which could facilitate the metabolism of glucose and short-chain fatty acids. Among the four main areas of improvement identified in relation to probiotics, a 16-week multi-strain supplementation protocol showed improved aerobic performance and exertion rate in amateur cyclists. Conclusions: Despite the limited number of studies, certain microbiota traits could be identified in competitive cyclists, which may correspond to their high metabolic rate. Although further strain standardized studies are needed on professional cyclists, the data could indicate that certain probiotic supplementation may be an effective addition for competitive cyclists.

Background: Few studies have analyzed the medium- to long-term effects of warm-up protocols on biomechanical and performance parameters in athletes. This study evaluated the effects of a 3-week foam rolling (FR) protocol integrated into the initial phase of the warm-up on ankle dorsiflexion parameters and jumping performance through the countermovement jump test (CMJ) in young rhythmic gymnasts. Methods: Twenty-six female young rhythmic gymnasts who met the inclusion criteria participated in the study and were divided into the FR group ( n = 12; Age = 13.2 ± 2.59 years; Height = 152.3 ± 13.34 cm; Weight = 39.9 ± 11.22 kg) or the C (Control) group ( n = 14; Age = 13.4 ± 2.17 years; Height = 149.5 ± 13.33 cm; Weight = 40.6 ± 10.14 kg). An initial evaluation (T0) and an evaluation after the 3-week FR warm-up protocol were conducted. An inertial sensor was used to analyze ankle dorsiflexion using the following parameters: range of motion (ROM) (°), angular velocity (°/s), and fluency index (0–1). An optical detection sensor detected the jump height and flight time of the CMJ test. Results: Significant differences were found between T0 and T1 in the FR group and between the FR group and the C group at T1. Significant between-subject interaction effects (F = 32.58; p < 0.001; ηp ² = .576) and group-by-time interaction effects (F = 9.73; p < 0.01; ηp ² = .288) were found. Specifically, significant enhancements in CMJ performance ( p < 0.001) and angular dorsiflexion velocity of the right ankle ( p < 0.05) were noted after the intervention in the FR group. Conclusions: Our results suggest that a 3-week FR intervention incorporated into the warm-up routine of young rhythmic gymnasts led to an increase in jump performance, but not in ankle dorsiflexion ROM parameters. Further studies are necessary to investigate the effects of warm-up on biomechanical parameters using longer FR protocols. Trial registration: NCT07113249. Registration date: 02/08/2025.

Introduction or background: Residual fatigue following resistance exercise can impair neuromuscular performance. The back squat (BSQ) and deadlift (DL) are key lower-limb exercises but may differ in their fatigue and recovery profiles. Identifying phase-specific markers during the countermovement jump (CMJ) may improve monitoring and guide recovery strategies. Sources of data: Fifty-four resistance-trained adults (≥1 year experience) were randomly assigned to BSQ, DL, or control (CON) groups. After one-repetition maximum (1RM) estimation, BSQ and DL completed a fatiguing protocol (3 × 12 repetitions at 70% 1RM). CMJ performance was assessed at baseline, immediately, 30 min, and 24 h post-exercise using a force platform. Phase-specific force–time variables and the modified reactive strength index (RSImod) were calculated; muscle soreness was recorded at 24 and 48 h. Areas of agreement: Both BSQ and DL caused significant decrements in CMJ-derived metrics, as indicated by a linear mixed-effects model, and greater soreness than control, according to a two-way mixed analysis of variance (ANOVA). BSQ produced larger and earlier impairments across force, displacement, and work variables, whereas DL showed smaller but more persistent reductions in braking rate of force development (RFD) and RSImod. Areas of controversy: Despite similar soreness, recovery patterns differed, indicating distinct neuromuscular demands and time courses between exercises. Growing points: Phase-specific CMJ metrics particularly braking and unloading RFD, eccentric/concentric work, and RSImod are sensitive indicators of residual fatigue. Areas timely for developing research: Future studies should integrate electromyographic and biochemical markers and extend observation beyond 48 h to describe full recovery trajectories.
