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.    .

This retrospective study aimed to examine the incidence, types, and patterns of injuries and illnesses among female cricketers in the first-class cricket of Bangladesh between 2015 and 2021. The study was conducted with 250 female cricket players aged 14-28 who had experienced injuries. Participants completed a structured questionnaire that gathered information on injury type, frequency, recurrence, treatment methods, and post-injury performance. Logistic regression analysis was employed to assess the relationship between injury risk and key variables, including playing position (batter, bowler, or fielder), weekly workload (hours spent in training/competition), and injury context (occurring during matches or practice). Descriptive statistics were used to summarize injury patterns and recovery outcomes, while odds ratios (OR) with 95% confidence intervals (CI) were calculated to identify significant predictors of injury risk. Of the participants, 75.2% experienced new injuries, while 24.8% reported chronic injuries. The most common injury sites were the knee/leg (24%) and shoulder (20%). Recurrence was high, with 56% experiencing 5-6 injury recurrences, and 68% reported multiple injuries over their careers. Physiotherapy was the primary treatment, used by 52% of participants, and 76% of players returned to competition post-injury. However, only 8% regained their pre-injury performance levels. Logistic regression revealed that bowlers had a significantly higher injury risk (OR = 2.12, p = 0.055), while high workloads (21+ hours/week) were also associated with increased injury risk (OR = 1.42, p = 0.112), though not statistically significant. The findings highlight the prevalence of injuries in female cricket, particularly in bowlers and those with high workloads. Physiotherapy was effective in promoting recovery, but a significant portion of athletes did not regain their pre-injury performance levels. Comprehensive injury prevention programs, tailored rehabilitation, and ongoing education on injury management are essential to mitigate risks and enhance player recovery.

The best medical care for female football athletes should be evidence-based, and patient- and context-specific. A 2019 scoping review identified key knowledge gaps relating to the health of female footballers. Since then, research in women's football has been intensifying. To aid in the direction of future research, this study aims to scope peer-reviewed, illness-related research in women's football. Five databases were searched in July 2023. In combination with identified studies from the 2019 review, 72 studies were included for data extraction of sample characteristics (age, playing level, geography), illness characteristics according to IOC guidance, and broader research themes. Results reveal an overall lack of quantity and variety in illnesses investigated, with a growing popularity in mental health research. Minimal female athlete-specific illnesses were identified. Future research must address urgent female-specific illness topics, and also consider where knowledge from adjacent populations might be safe to adapt into women's football.

Female Rugby Union players were affected by contact breast injuries (CBI) and exercise-induced breast pain (EIBP). Hundred and eighty-two female Rugby players from 25 different countries reported incurring a CBI or EIBP which affected sport performance. A higher percentage of 7s players (7s: 64.3%, 15s: 51.9%) reported at least one CBI over a 12-month period. EIBP frequency, during the same period, was notably low for 7s and 15s. Sprinting, jumping and running were the most frequent activities precipitating the severest EIBP. Being tackled or tackling most frequently caused a CBI. Respondents affected by either CBI (57.3%) or EIPB (51.3%) reported always playing-on during matches despite their pain or injury. Between 19.4% and 32.1% of the respondents did not have a CBI or EIBP prevention strategy. A paucity of player knowledge on prevention strategies was noted, indicating a need for education addressing breast pain and injury among players.

This study aimed to examine the effects of 6-week vibration (VFR) and non-vibration foam rolling (FR) on muscle strength, hamstrings-to-quadriceps (H:Q) ratio, flexibility, and dynamic balance in soccer players. Thirty-six players were included in the study. The players were randomly assigned to either VFR (n=12), FR (n=12), or control group (CG) (n=12). The players in VFR and FR groups performed VFR or FR thrice per week for 6 weeks. The CG did not receive any intervention. Pre- and post-test assessment included muscle strength, H:Q ratio, flexibility, and dynamic balance. Dominant extremity knee flexor and non-dominant extremity knee flexor and extensor muscle strength improved in VFR and FR groups (p<0.05). Flexibility and dynamic balance improved in VFR group (p<0.05). Both 6-week VFR and FR increased muscle strength without affecting H:Q ratio. VFR was more effective than FR for improving flexibility and dynamic balance. The results can be stunning for performance enhancement.

Objective: This study aims to determine the impact of increased anterior pelvic tilt angle on hamstring muscle injuries in football players. An independent t-test was performed to compare right and left anterior pelvic tilt angles.

Design: The study was conducted by monitoring 76 different players from a professional club in the Premier Division of Professional Football League over a period of five years. During this time, the hamstring injuries sustained by the players and their severity were recorded using MRI imaging techniques.

Result: The comparison of the right and left anterior pelvic tilt angles among players was analysed using an independent t-test for independent groups. The Receiver Operating Characteristic (ROC) analysis was used to determine the threshold value that categorizes the right and left angles. According to the results, a significant impact of the variation in right-left anterior pelvic tilt angle on hamstring muscle injuries was observed (p < 0.05). However, no significant effects were found for the Q angle, tibial torsion, or knee posture (p > 0.05).

Conclusion: In conclusion, it can be stated that an increase in the anterior pelvic tilt angle is associated with a higher frequency of hamstring injuries.

The present scoping review aims to describe the available criteria to determine Return-To-Play (RTP), propose methodological considerations and new research questions, and provide information to help practitioners in professional football make informed decisions regarding RTP following a hamstring strain injury (HSI) in professional male football. The following electronic databases were searched: PubMed, MEDLINE, web of science and SPORTDiscus using keywords related to HSI in elite football. All types of studies in English reporting at least one RTP criterion for professional football players who sustained an HSI were included. In total, 19 studies met the inclusion criteria. RTP criteria were divided into three categories: clinical, strength and performance criteria. Clinical criteria were also divided into sub-categories: absence of pain, hamstring flexibility, medical staff clearance, psychological readiness, surgeon's opinion and imaging. Practitioners working in professional male football could benefit from using a combination of criteria in their RTP battery of tests.

Recovery dynamics in combat sports like judo are critical for optimizing performance and reducing injury risk. This study aimed to evaluate the time-course of physiological (creatine kinase, CK) and neuromuscular (countermovement jump, CMJ) recovery in junior judo athletes following competition. Thirteen junior-level judo athletes participated in this study. Assessments of CK and CMJ were conducted at three points: 24 hours before, 24 hours after, and 48 hours after competition. A repeated-measures ANOVA was used to analyse differences across time points, and Pearson's correlation measured associations between match duration and recovery markers. CK levels showed a significant increase 24 hours post-competition, returning to baseline by 48 hours, indicating muscle damage peaks shortly after matches. CMJ performance remained stable across all time points, suggesting a different recovery pathway for neuromuscular function. Additionally, match duration correlated with CK increase, reflecting higher physical stress. This study highlights a distinct recovery pattern for CK and CMJ, with CK peaking 24 hours post-match and CMJ showing resilience to acute competition stress. Coaches and athletes can use these findings to tailor recovery interventions, focusing on muscle recovery within the first 24 hours to optimize performance and reduce injury risk in subsequent events.
