This systematic review aimed to evaluate the effectiveness of different physical rehabilitation strategies for young volleyball players after meniscectomy, focusing on tailored protocols that enhance return-to-sport (RTS) outcomes. A comprehensive literature search was conducted across multiple databases, including PubMed, Web of Science, Scopus, Cochrane Library, and Google Scholar from January 2010 to January 2025. The quality assessment of the studies was analysed using the Critical Appraisal Skills Program (CASP) tool. Furthermore, data extraction and synthesis were performed in accordance with PRISMA guidelines. This review revealed the importance of structured, personalized rehabilitation protocols that address the unique demands of volleyball. High-quality rehabilitation significantly improves physical recovery, mental fitness, and overall athletic performance. Evidence suggests that early RTS is achievable, with approximately 77% of athletes returning to sport within two months of surgery. A phased approach to rehabilitation, addressing both immediate recovery and long-term health, was shown to be essential in preventing reinjury. This systematic review supported an evidence-based, multimodal rehabilitation approach tailored to the specific needs of young volleyball players after meniscectomy. By focusing on the athlete's immediate recovery and long-term health, clinicians can improve functional outcomes and minimize the risk of re-injury.

The purpose of this study is to examine Achilles Tendon (AT) rupture and prior injury in the National Basketball Association (NBA). Publicly available data was sourced via two online databases and filtered to identify those reported as having sustained AT rupture. A full injury history was then generated for those players. A total of 51 AT ruptures were identified. Thirty-five per cent (18) had previously missed at least one game for "Achilles tendinitis" or "Achilles tendon injury" on the side of the affected limb. A further 18% were noted to have suffered plantar fasciitis or foot inflammation (9) or previous ankle injury (9). Seven previous injuries were knee related, and five were described as calf muscle injuries. The remaining three had prior soft tissue injuries to the quadriceps, hamstring or groin. Understanding any potential association between previous small time-loss injuries and large time-loss injuries such Achilles tendon ruptures is an important step in advancing injury risk mitigation strategies in professional basketball.

The aim of this cross-sectional study was to assess the test-retest reliability and concurrent validity of the Unilateral Seated Shot-Put Test (USSPT) in patients with subacromial pain syndrome (SAPS). Twenty three patients were included in the study. The participants were assessed using the USSPT for functional power; Visual analog scale (VAS) for pain at activity; Disabilities of the Arm, Shoulder, and Hand Questionnaire (DASH) and Shoulder Pain and Disability Index (SPADI) for disability, hand-held dynamometer for shoulder flexion and shoulder abduction muscle strength, and grip strength. Test-retest reliability of the USSPT was found excellent with an intraclass correlation coefficient (ICC_2,1) score of 0.976, a standard error of measurement (SEM) of 12.47, and a minimum detectable change (MDC₉₅) score of 34.54. There was high to excellent correlations between the USSPT and the SPADI (r = -0.756, p = <0.001), shoulder flexion muscle strength (r = 0.834, p = <0.001), and shoulder abduction muscle strength (r = 0.711, p = <0.001). SPADI score and shoulder flexion muscle strength were the most important factors influencing USSPT performance, accounting for 73.3% of the variance. The USSPT is a reliable and valid test for assessing upper extremity functional power.

To date, no literature exists on mountain biking injuries in coaches. This study described cross-country mountain biking injuries among coaches in National Interscholastic Cycling Association (NICA) sanctioned leagues from 2018 to 2022. Data were collected using the NICA injury surveillance system (ISS), a web-based injury and exposure reporting system for youth mountain biking, and were analysed using descriptive and univariate inferential statistics. A total of 401 injury events, including 661 distinct time-loss injuries, were reported in 59,545 coach-years over five seasons, resulting in an injury event proportion of 0.67%. The median time-loss due to injury was about 31 days for all injured coaches. The most commonly injured body part was shoulder/clavicle (32.7% of all injury events), followed by head/concussion (18.0% of all injury events) and wrist/hand (17.7% of all injury events). Fracture was the most common diagnosis (27.1% of all non-head injuries). Male coaches sustained upper-limb injuries significantly more often than did female coaches (62.9% vs. 51.5%; p = 0.044), whereas the rate of lower-limb injuries was significantly higher among female coaches than male coaches (33.3% vs. 17.9%; p = 0.001). Fractures and concussions are the most common diagnoses. These findings could be used for designing future injury prevention programmes.

Our study was aimed to describe the maturation pattern of the tibial tuberosity in association with chronological age in children and adolescent athletes. This was a single centre cross-sectional study on 116 subjects, 63 males and 53 females, with ages between 7 and 18 years. All participants were performance athletes, members of sports clubs, participating in daily training. All subjects were examined for symptoms related to Osgood-Schlatter disease (OSD) and evaluated by ultrasound of the knee in order to establish the maturation stage of the tibial tuberosity based on a 4-point scale. Tibial tuberosity maturation stage was distributed as follows: stage 1 (n = 31, 26.7%), stage 2 (n = 9, 7.8%), stage 3 (n = 27, 23.3%) and stage 4 (n = 49, 42.2%). Only three cases presented symptoms associated with OSD, which results in a very low prevalence of only 2.6%. Between the ages of 13 and 15 years, female subjects showed higher proportions of complete bone maturation compared to males. Our study provides information about the gender offset of tibial tuberosity bone maturation.

The National Interscholastic Cycling Association Injury Surveillance System was implemented in 2018 to characterize acute traumatic injuries and identify associated risk factors in interscholastic youth cross-country mountain bike racing in the United States. Designated reporters collected data weekly during the 2018-2022 seasons. Variables collected included demographic information, injury characteristics, and other associated factors. In 119,098 student-athlete years, there were 2,655 injury events (injury event proportion = 2.23%). The wrist/hand was the most common body part injured (23.2%), followed by head/brain (23.0%), and shoulder/clavicle (15.9%). Males experienced a higher proportion of upper limb injuries than females (57.6% and 49.6%, respectively; p < 0.001); females experienced a higher proportion of lower limb injuries than males (29.5% and 24.8%, respectively; p = 0.020). Injury event proportion decreased by 27% (p < 0.001) during the study period. Acute traumatic injuries are common but injury proportion is low. Most injuries are minor but serious injuries do occur, resulting in time-loss from riding.

A 12-week randomized controlled trial was conducted to evaluate the effects of an education and exercise-based programme among competitive youth volleyball athletes. Forty-five participants were randomized into intervention (n = 23) and control groups (n = 22). The intervention group attended the "Education program for youth athletes" in Week 1 and the "Exercise program" over 12 weeks. The education programme improved participants' knowledge scores concerning overuse injuries and the growth and maturation process during adolescence from baseline to Week 12 (p = .001). The exercise programme improved shoulder internal rotation range of motion after 12 weeks (p < .001). No significant improvements were observed for eccentric shoulder external rotation strength and thoracic rotation range of motion following the exercise programme in the intervention group. The education and exercise-based programme improved knowledge regarding overuse injuries and the adolescence growth process and shoulder internal rotation range of motion among youth volleyball athletes.

We aimed to assess the associations between physical activities of reference teams or the differences with their opponents, and the goals scored in professional soccer. Total distance (TD), distance >20 km/h (VHS) and goals scored during matches of the Serie-A by two Best and two Worst Teams and by their opponents were collected. Odds ratio (OR) of scoring goals when high or low levels of running, as well as higher or lower levels compared to their opponents, were estimated. Performing higher TD than the opponents increased the OR of scoring goals for Best and Worst Teams in 5-min (19.8 ± 5.2, 16.1 ± 7.3) and 15-min (11.5 ± 3.3, 11.5 ± 4.9) intervals. Performing more VHS than the opponents increased the OR of scoring for Best and Worst teams in 5-minute (3.7 ± 0.9, 2.5 ± 0.6) and for Best teams in 15-minute (3.3 ± 1.1) intervals. Odds of scoring were higher when relative differences in running activities between teams, instead of absolute levels, were considered.

Relationship between ability to perform the deep squat test (DST) and floating toes among baseball players with disabled throwing shoulder/elbow was retrospectively investigated. Players performed the DST by fully squatting while having their arms crossed in front of their chest without lifting the heel off the floor or falling backwards. Floating toes were evaluated if all the toes were in contact with the mat or not. The relationship between ability to perform the DST and prevalence of floating toes was statistically analysed. Sixty-three players (69.2%) were unable to perform the DST. Floating toes were observed in 74 players (81.3%). Players with inability to perform the DST had significantly higher prevalence of floating toes (58 players, 92.1%), compared with those who were able to perform the test (16 players, 57.1%) (p < 0.001). Floating toes may relate with inability to perform the DST among baseball players with disabled throwing shoulder/elbow.

This study examined the effect of a 40-min nap (N40) the day after a night session of the Loughborough Intermittent Shuttle Test (LIST), before, during and after Ramadan. In a randomized crossover design, fifteen male soccer players completed the LIST in the evening (2100h), followed by either a N40 or no nap (N0) the next day, at 1400h. Performance on the 5-m shuttle run test (5mSRT), digit cancellation test (DCT), and subjective measures (i.e., sleepiness, rating of perceived exertion, and muscle soreness) were assessed at 1700h. During Ramadan, 5mSRT and DCT performance decreased compared to before Ramadan in the N0 condition (p<0.05). However, N40 improved 5mSRT and DCT performance across all periods compared to N0 (p<0.05). In conclusion, a 40-min of nap opportunity is an effective strategy for improving physical and cognitive performance during and following Ramadan after a bout of exercise the previous night.    .
