Acute effects of static stretching (SS) and proprioceptive neuromuscular facilitation (PNF) on local and non-local range of motion (ROM) were assessed in 29 participants. Three evaluations were performed one week apart: week-1 Control session (CS); weeks 2-3 either SS or PNF interventions (randomized). Dominant and non-dominant limbs, local (hamstring extensibility) and non-local ROMs (Shoulder extension-ShE) were collected at baseline (T0), immediately after (T1), and fifteen minutes post-intervention (T2). No differences were found between time-points during the CS. Local-ROM significantly increased (p=0.0002, ES=0.74 and 0.0079, 0.56, for dominant and non-dominant lower limbs, respectively) after both SS and PNF. No interaction between time and treatment was detected for ShE in both limbs. However, post-hoc analysis revealed a significant increase in dominant upper limb ShE between T0 and T1 only after SS (p=0.002; +6.5%). Acute bouts of SS and PNF can increase local-ROM, however, no clear effects were observed for non-local ROM.
对 29 名参与者进行了静态拉伸(SS)和本体感觉神经肌肉促进(PNF)对局部和非局部运动范围(ROM)的急性影响评估。三次评估间隔一周:第 1 周为对照组(CS);第 2-3 周为静态拉伸或本体感觉神经肌肉促进(PNF)干预组(随机)。分别在基线(T0)、干预后立即(T1)和干预后 15 分钟(T2)收集优势和非优势肢体、局部(腿筋伸展性)和非局部 ROM(肩关节伸展-ShE)的数据。在 CS 期间,各时间点之间未发现差异。SS和PNF治疗后,局部ROM明显增加(P=0.0002,ES=0.74,优势和非优势下肢分别为0.0079和0.56)。在双侧肢体的 ShE 方面,未检测到时间与治疗之间的交互作用。然而,事后分析显示,只有在 SS 后,优势上肢 ShE 在 T0 和 T1 之间才有显著增加(p=0.002;+6.5%)。急性阵发性 SS 和 PNF 可以增加局部 ROM,但对非局部 ROM 没有观察到明显的影响。

This study retrospectively compared the effect of holding the 2022 FIFA World Cup™ (WC) mid-season (season 2022/23) on injury rates and patterns in French Ligue 1 soccer clubs. Epidemiological data in 17 clubs were prospectively recorded by their physicians. Time-loss injuries (injuries leading to a player being unable to fully participate in play over the following 72-hour period) were compared with those reported during a regular season (2021-22). In the WC season, an increase of approximately 23% (training + match-play) was observed for both the total number of injuries and knee, ankle and muscle injuries combined. Incidences for match-play injury overall and for the knee, ankle and muscle regions combined and the hamstrings and calf regions specifically also rose significantly (range: p < 0.05-p < 0.01). These results suggest that injury occurrence and patterns in French L1 soccer clubs were substantially affected during the 2022/23 season when a mid-season WC was held.

This study aimed to investigate physiological and pathological Glenohumeral Internal Rotation Deficit (GIRD) in volleyball players with and without a history of shoulder pain. Volleyball players with a history of shoulder pain (n = 18) and without a history of shoulder pain (n = 18), who were matched in age, weight, height, BMI, years of experience and frequency of practice were recruited for this cross-sectional study. Shoulder internal and external rotation Range of Motion (ROM) was measured for the dominant and non-dominant shoulders of each participant using a digital inclinometer. Measurements of GIRD, External Rotation Gain (ERG), and Total Range of Motion (TROM) were calculated. There were significantly higher degrees of GIRD in the pain group (15.65⁰) than the no-pain group (9.06⁰) (p=0.004) and significantly higher differences in the TROM in the pain group (16.17⁰) than the no-pain group (10.17⁰) (p=0.007). There was no correlation between the level of pain and the presented ROM adaptations. The study showed that for volleyball players, pathological GIRD should be defined at 10-18⁰ degrees of GIRD that are accompanied by differences in the TROM that exceeds 8⁰.
本研究旨在调查有肩痛病史和无肩痛病史的排球运动员的盂肱内旋缺陷(GIRD)的生理和病理情况。这项横断面研究招募了有肩痛史(18 人)和无肩痛史(18 人)的排球运动员,他们在年龄、体重、身高、体重指数、训练年限和训练频率方面均相匹配。使用数字倾角仪测量每位参与者的优势肩和非优势肩的肩关节内旋和外旋活动范围(ROM)。并计算了GIRD、外旋增益(ERG)和总活动范围(TROM)的测量值。疼痛组的 GIRD(15.65⁰)明显高于无疼痛组(9.06⁰)(P=0.004),疼痛组的 TROM(16.17⁰)明显高于无疼痛组(10.17⁰)(P=0.007)。疼痛程度与呈现的 ROM 适应性之间没有相关性。研究结果表明,对于排球运动员来说,病态的GIRD应定义为10-18⁰度的GIRD,同时伴有超过8⁰的TROM差异。

The purpose of the study was to compare the effectiveness of physiotherapist-supervised and home-based exercises after platelet-rich-plasma (PRP) injection in knee osteoarthritis (OA). Thirty women (mean age = 57.83 ± 7.26 years; mean weight = 72.13 ± 15.54 kg; mean height = 158.40 ± 4.49 cm; mean body mass index = 28.75 ± 6.18 kg/m2) were included. Patients randomized either supervised or home-basedexercise-group after PRP. Both groups performed 6-week (3 times/week) exercise. Pain, hip and knee muscle strength, and knee functions were assessed before and after exercise. The median improvement in the pain from baseline to 6th week was 3.80 (2.85-5.55) point in-supervised-exercise-group while it was 0.60 (-0.10-2.55) point in home-based-exercise-group (p = 0.002). The median improvement in knee function was 22.91 (13.02-30.20) in supervised-exercise-group overtime (p < 0.001). There was no improvement in knee function following home-based exercises (p = 1.000). The supervised-exercise-group revealed a significant improvement in hip (median difference = 32.00 (8.30-88.95), p = 0.011); quadriceps (median difference = 32.10 (21.65-60.05), p = 0.001) and hamstring (median difference = 27.90 (7.95-37.65), p = 0.022) strength overtime. The physiotherapist-supervised exercises after PRP had better effects on pain and knee function than the home-based exercises.

Safe return to sport (RTS) after anterior cruciate ligament reconstruction (ACLR) surgery is important. Core stabilization is common within rehabilitation, but its influence on hopping performance and single-leg landing kinetics among athletes post-ACLR is unclear. Twenty-four male professional athletes who had ACL reconstruction surgery (time since surgery = 11.47 ± 1.55 months) were recruited and randomly assigned to exercise (n = 12) and control (n = 12) groups. Exercise group received an 8-week core stability exercise program. Limb symmetry index (LSI) for single-leg hop for distance (SLH) and triple hop (TRH) tests, and single-leg landing kinetics (multidirectional ground reaction forces) were measured pre- and post-intervention. In post-test, the participants in exercise group were more symmetrical in SLH (P = .04, CI = 0.01-7.68) and TRH (P = .01, CI = 0.28-11.1) distances. They also improved their LSI values for vertical ground reaction force (vGRF), though not significantly (P < .05). LSI for anteroposterior (a-p) and mediolateral (m-l) GRFs remained unchanged for participants of both groups. Our findings indicate the positive effect of core exercise on decreasing between-limb asymmetries during SLH and TRH tests. Our results demonstrate that despite lack of change in kinetics, functional performance is more symmetrical following core stability training.

This study aims to investigate the fear or failure (FoF) in Brazilian runners of both sex, performance levels and age categories, as well as to verify the relationship between FoF and socioeconomic status (SES). Sample size as composed by 916. Age, sex, body height, body weight, SES, and running pace were self-reported. The Multidimensional Questionnaire of FoF was applied in an online platform. Running pace, and SES were categorized and processed through multivariate analysis and Spearman correlations, with the p-value set at 0.05. Female runners with better performance (2.13 ± 0.74) and younger (2.16 ± 0.80), as a well as male runners with worse performance (2.04 ± 0.69) and older (2.04 ± 0.89) presented the highest values of FoF. Among women, SES was negatively associated with FoF (r = -0.144; p = 0.006), while a positive association between running pace and SES was observed among men (r = 0.290; p < 0.001). Non-professional Brazilian runners presented low values of FoF.

The present study evaluated the mental health (MH) of athletes according to a range of variables, including SARS-CoV-2 infection status and sport-specific factors. An online survey was sent to 1636 Turkish professional athletes incorporating standardized scales assessing athlete-specific stress, depression, and anxiety. A total of 579 professional athletes (29% SARS-CoV-2 positive) participated in the study. While female athletes reported higher anxiety scores than males (p < 0.01), the depression scores of the athletes who had been infected with SARS-CoV-2 were significantly higher than athletes who were not infected (p = 0.03). Higher athlete-specific stress, depression, and anxiety scores were associated with participating in an individual sport, experiencing chronic pain, severe sports injury history, and performance concerns (all p < 0.01). MH symptoms in athletes were associated with being infected with SARS-CoV-2, female gender, participating in an individual sport, and performance concerns. MH assessments should be undertaken with athletes to detect vulnerabilities and enable appropriate and timely MH interventions.

This study aimed to determine the effects of walking exercise to induce a mild energy deficit and to improve body composition and metabolic status in postmenopausal women (PMW) with obesity as means of minimizing endocrine disruption and maintaining bone health. Twenty-four PMW with obesity (age: 55.0 ± 3.7 y, BMI: 32.9 ± 4.2 kg/m2, percent body fat: 46.2 ± 3.6%) were randomly assigned into either exercise (n = 12) or control (n = 12) groups. Exercise group participated in a-10 week supervised progressive walking programme and control group maintained regular habits. Pre- and post-training assessments included body composition, bone mass, peak oxygen uptake (O2peak), osteocalcin, bone alkaline phosphatase (BAP), type I collagen cross-linked C-telopeptide (CTX)glucose, glycated haemoglobin (HbA1c)), leptin and adiponectin. Results: Following the training program, body weight (2.6%; p < 0.001), fat mass (4.5%; p = 0.002), resting glucose (6.8%; p = 0.017), and HbA1c (3.7%; p = 0.047) decreased, while relative O2peak (16%; p < 0.001) increased in the exercise group. Leptin, adiponectin, CTX, osteocalcin or BAP did not change in either group. In conclusion, small dose of aerobic exercise improves key markers of metabolic health in PMW with obesity without negatively affecting markers of bone metabolism.

Cardiac sequelae following sport-related concussion are not well understood. This study describes changes in the cardiac cycle timing intervals and contractility parameters during the acute phase of concussion. Twelve athletes (21 ± 2 years, height = 182 ± 9 cm, mass = 86 ± 15 kg, BMI = 26 ± 3 kg/m2) were assessed within 5 days of sustaining a diagnosed concussion against their own pre-season baseline. A non-invasive cardiac sensor (LLA RecordisTM) was used to record the cardiac cycle parameters of the heart for 1 minute during supine rest. Cardiac cycle timing intervals (Isovolumic relaxation and contraction time, Mitral valve open to E wave, Rapid ejection period, Atrial systole to mitral valve closure, Systole, and Diastole) and contractile forces (Twist force and Atrial systole: AS) were compared. Systolic time significantly decreased during acute concussion (p = 0.034). Magnitude of AS significantly increased during acute concussion (p = 0.013). These results imply that concussion can result in altered systolic function.

Commonly we see large within-age-group variations in physique, including body mass, stature, and percentages of predicted adult height, which suggests that age-specified training loads are flawed. Aims were to investigate how maturation impacts training load and neuromuscular response within academy soccer and to provide recommendations for practitioners. Fifty-five male soccer players (age 14.5 ± 1.2 years; stature 172 ± 10 cm; body mass 59.8 ± 10 kg; 94.1 ± 1.8% predicted adult height) reported differential ratings of perceived exertion (AU) across a season. Neuromuscular performance (countermovement jump, reactive strength index, absolute and relative leg stiffness) was measured at three time points across the season. Perceived exertion and neuromuscular performance were examined using linear mixed modelling, supplemented with non-clinical magnitude-based decisions. Analysis indicates every 5% increase in maturity status results in players perceiving overall session intensity 6.9 AU lower and 13.9 AU lower for a 10% maturity shift. Both 5% and 10% changes in maturity most likely resulted in higher countermovement jump, with likely to very likely differences observed for RSI and ABS. Maturity substantially influences neuromuscular performance over the season. Therefore, maturity-specific load prescription may prevent significant within age-group differences in accumulated load, possibly reducing injury risk and/or burnout.
