Objectives
To evaluate upper limb performance, trunk extensor endurance, and serratus anterior strength in para swimmers over a sports season.
Design
A cohort study conducted over eleven months.
Settings
Three assessments were performed at pre-season, mid-season, and post-season, evaluating the CKCUEST, Sorensen Test, and isometric strength of the serratus anterior.
Participants
Twelve para swimmers from a sports center.
Main outcome measures
Generalized Mixed Models were used to assess seasonal changes and the influence of sex, age, type of impairment, and season phase. Coefficients of variation for each variable were calculated along with 95% confidence intervals (CIs), with a 5% significance level.
Results
Sorensen Test values decreased during the season (C: 22.0; CI: 33.9 to −10.4; p < 0.01). A serratus anterior isometric strength difference was observed post-season between para athletes with motor impairments and those with visual/intellectual impairments on the dominant side (C: 3.3; CI: 6.2 to −0.5; p = 0.02).
Conclusion
Sorensen Test values declined in mid-season, and para athletes with motor impairments showed lower serratus anterior strength in post-season. CKCUEST values remained stable throughout the season.

Objectives
The aim was to investigate changes in sedentary time during an activity modification strategy for sports-active adolescents with patellofemoral pain (PFP) and Osgood-Schlatter (OSD).
Design
Explorative ancillary analysis of two different prospective clinical trials with two different endpoint timelines.
Methods
202 adolescents with either PFP or OSD were included. ActiGraph GT3X + objectively measured sedentary time before, during, and after adolescents were instructed to modify sports participation, requiring a minimum of 4 days with 10 h of wear time. Daily sedentary time was calculated from ≥10 min of consecutive bouts.
Results
138 adolescents with PFP and 47 with OSD were eligible for inclusion. Adolescents with PFP had a non-significant increase of 14min/day change in sedentary time from baseline to during the activity modification. Adolescents with OSD had non-significant increases of 9min/day and 0min/day in sedentary time from baseline to immediately following the activity modification period and at the 12 weeks follow-up. There was variability in the individual adolescents’ sedentary time during the intervention.
Conclusion
Activity modification in adolescents with PFP or OSD was associated with none, or only small systematic changes in sedentary time.

Objectives
To determine the incidence, severity, and nature of injuries sustained by female trail runners and investigate selected training variables as risk factors for injuries.
Training metrics (average weekly number of running sessions, mileage (km), session duration (mins), pace (min/km), ascent (m) and descent (m), number of running doubles per week, number of cross training doubles per week, type of cross training), incidence, severity and nature of trail running injuries sustained in the previous 12 months.
Results
The injury incidence was 14.3 injuries per 1000 h and mean severity score (OSTRC- H) was 80.95 ± 21.74. The main anatomical region affected was the lower limb (63.4%), primarily the ankle (13.9%), knee (13.0%) and lower leg (12.2%). The most common injury was tendinopathy (25.2%). A higher number of injuries sustained in the previous 12 months was weakly associated with a higher average duration of other (not trail) weekly running sessions (p = 0.017).
Conclusions
Findings from this study could inform future injury prevention and treatment strategies. Prospective, longitudinal data on injuries in female trail runners is needed.

Objectives
To assess physiotherapist delivery fidelity and identify factors optimising delivery fidelity of an intervention based on recommended guidelines for Achilles tendinopathy.
Design
A prospective repeated-measures observational study of physiotherapist delivery fidelity with carefully defined exercise and physical activity advice.
Setting
An inter-disciplinary clinic in Melbourne, Australia, embedded in a randomised controlled trial.
Participants
Two physiotherapists delivering the intervention to five participants each, at three timepoints.
Intervention
All participants were expected to receive the same intervention. Feedback at timepoint one, guided boost-training to optimise delivery fidelity.
Main outcome measures
Proportion of exercise and physical activity advice components delivered as intended (high ≥80%; moderate 51–79%; low≤50%), with relationships between variables analysed using chi-square tests.
Results
Physiotherapist delivery fidelity improved significantly between timepoint one and two (χ2 = 83.3, p < 0.001), then sustained at timepoint three. At timepoint one, seven (70%) of intervention components were delivered with high fidelity, one (10%) with moderate fidelity and two (20%) with low fidelity. At timepoint two, after boost-training, nine (90%) were delivered with high fidelity and one (10%) with moderate fidelity. At timepoint three, all intervention components (100%) were delivered with high fidelity by both physiotherapists.
Conclusion
Physiotherapist delivery fidelity can be optimised with feedback, collaboration and boost-training.

Isometric PF peak torque, with and without body mass normalization, at 0° and +20° of plantar flexion. Measurement reliability was evaluated using intraclass correlation coefficient (ICC), standard error of measurement (SEM) and minimal detectable change (MDC).
Results
Without normalization, measurement repeatability was excellent at 0° of plantar flexion (ICC, 0.94; SEM, 6.6%; MDC, 18.4%) compared with good repeatability at +20° (ICC, 0.85; SEM, 11.1%; MDC 30.6%). Measurement repeatability following normalization was good at 0° (ICC, 0.88; SEM, 5.2%; MDC, 14.4%) and +20° (ICC, 0.79; SEM, 10.2%; MDC, 28.1%). While reproducibility was good at 0° with normalization (ICC, 0.84; SEM, 5.9%; MDC, 16.3%) or excellent without (ICC 0.92; SEM 7.5%; MDC, 20.8%), it was moderate at +20° with normalization (ICC 0.71; SEM 11.3%; MDC, 31.3%) or good without (ICC 0.78; SEM 13.0%; MDC, 36.1%).
Conclusion
The reliability of PF maximal isometric strength is good/excellent at 0° of plantar flexion but moderate/good at +20°.

Objectives
The study was investigating the effect of a progressive resistance training program on the recovery of patients with anterior cruciate ligament reconstruction in terms of kinematics, kinetics and muscle strength.
Design
Longitudinal cohort study.
Setting
Hospital laboratory.
Participants
Of the 42 patients were finally included: 22 patients in the progressive resistance training group and 20 in the control group.
Main outcome measures
Questionnaire, single-leg vertical jump, and muscle strength were collected preoperatively and at 16, 28 weeks, and 1 year postoperatively.
Results
At 28 weeks, the height of the single-leg vertical jump for the injured knee was 203 and 157 mm (p = 0.045) and the peak knee flexion angle after landing for the injured knee was 31°and 23° (p = 0.027) in the progressive resistance training and control groups, respectively. The progressive resistance training group showed a significant increase in the knee extensor symmetry index after the 24-week exercise training compared from 58% preoperatively to 79% (p = 0.001) after training completion, which lasted up to 1 year postoperatively.
Conclusion
Progressive resistance training significantly improved knee extensor symmetry, single-leg vertical jump height, and peak knee flexion angle after landing, outperforming the control group across all measures.

Objectives
To describe the changes in hip adductor strength of professional women's football players over a season.
Design
One-season prospective study.
Setting
Facilities of a national first division club.
Participants
Professional women's football players.
Main outcome measures
Maximum hip adductor isometric strength in the long-lever and short-lever positions at four timepoints: early preseason, early season, mid-season, and end-season.
Results
Twenty-two players completed the study. Hip adductor strength values in early preseason (134 ± 29 N in the long-lever position and 317 ± 68 N in the short-lever position) were significantly lower than in the early season (171 ± 29 N and 363 ± 54 N) and mid-season (163 ± 23 N and 369 ± 53 N). By the end of the season (150 ± 19 N and 345 ± 39 N), strength values had significantly declined from both early and mid-season levels. Visual inspection of individual athletes' strength evolution over time reveals heterogeneous responses, with some players showing trajectories opposite to the group at specific time points.
Conclusions
Hip adductor strength increased from the preseason to the start of the women's football national league, remained stable during the first half of the league, but slightly declined in the second half. The heterogeneous responses among athletes underscore the importance of individualized monitoring throughout the season.

Objectives
Isolated rupture of the lateral collateral ligament (LCL) of the knee is extremely rare in professional football, and there is a paucity of literature describing the rehabilitation for this injury. This case report demonstrates the use of a return-to-performance (RTPerf) pathway that is time-independent, has clear criteria, and progressive phases to help inform decisions made by a multidisciplinary team (MDT).
Methods
A 25-year-old professional footballer sustained an isolated LCL rupture following a tackle by an opposing player, forcing his knee into excessive varus motion. Five days after the injury, the player underwent surgical repair of the LCL before commencing an RTPerf pathway.
Results
The player returned to team training 12 weeks after surgery before successfully returning to play (RTPlay) at 13.5 weeks. The player completed full RTPerf at 16 weeks and continued to play with no evidence of instability or pain.
Conclusion
This case report outlines how an RTPerf pathway can be successfully used to guide the management of isolated LCL ruptures of the knee.

Objective
To assess short term recovery between individuals with Achilles tendinopathy with varying degrees of kinesiophobia when treated with the Silbernagel protocol. Secondarily to investigate short term change in degree of kinesiophobia.
Design
Prospective single cohort analysis.
Setting
University/Clinical.
Participants
116 participants with midportion Achilles tendinopathy were grouped from their baseline Tampa Scale of Kinesiophobia (TSK) score: Low (≤33), Medium (34–41), and High (≥42).
Main outcome measures
Symptom severity, Achilles tendon structure, and function were assessed at baseline and 8-weeks following initiation of the Silbernagel protocol. Differences in recovery between TSK groups were analyzed.
Results
No group by time interactions were observed for symptoms, structure, or function. A significant interaction of group by time was observed for TSK score. The Medium (n = 66) and High (n = 28) TSK groups significantly decreased TSK score after 8 weeks by 2.4 and 4.4 points respectively while the Low TSK group (n = 22) did not change.
Conclusion
There were no differences in short term recovery of symptoms, Achilles tendon structure, and function in individuals with midportion Achilles tendinopathy treated with the Silbernagel protocol regardless of baseline degree of kinesiophobia. Those with moderate and high levels of kinesiophobia at baseline decreased TSK score in the short term.

Objectives
The study aimed to establish a normative reference value for the agility T-test and Illinois test in football players, on the basis of sex and playing position.
Design
Cross-sectional study.
Setting
Himachal Pradesh Football Association and Maharishi Markandeshwar Medical College and Hospital-Himachal Pradesh.
Participants
138 football players including 69 male and 69 female players aged 18–25 years were included.
Main outcome measures
Illinois and agility T-test.
Results
Normative values of male and female player's are established for agility T-test 10.06 ± 0.87; 11.27 ± 0.84 and for Illinois test were 15.56 ± 0.80; 17.75 ± 1.37 s, respectively. Mann Whitney U- test was used to compare the agility of both sexes and showed a significant difference (p-value <0.001) in male and female players. Intra-rater reliability was checked for between trials and revealed excellent reliability with greatest single measure ICC (0.972) and average measure ICC (0.936) for Illinois test and single measure ICC (0.891) and average measure ICC (0.903) for agility T-test.
Conclusion
Both agility tests concluded that female players are statistically and clinically less agile than male players. Similar results were found when agility was compared according to playing position. On the basis of sex, midfielders are more agile compared with other playing position.
研究旨在根据性别和踢球位置，确定足球运动员敏捷性 T 测试和伊利诺伊测试的标准参考值。结果男女球员的标准值分别为：敏捷性 T 测试 10.06 ± 0.87；11.27 ± 0.84；伊利诺伊测试 15.56 ± 0.80；17.75 ± 1.37 秒。曼-惠特尼 U 检验用于比较男女运动员的敏捷性，结果显示男女运动员的敏捷性差异显著（P 值为 0.001）。伊利诺伊测试的单次测量 ICC 最大（0.972），平均测量 ICC 最大（0.936）；敏捷性 T 测试的单次测量 ICC 最大（0.891），平均测量 ICC 最大（0.903）。根据球员位置对敏捷性进行比较也发现了类似的结果。根据性别，中场球员的敏捷性高于其他位置的球员。
