Daytime sleepiness in Chinese professional, semi professional and students soccer players in the Shanghai lockdown
ConclusionsThis study shows the first data on sleepiness in Chinese soccer players of different level of qualification immediately post lockdown condition. Professional male ’s players sleepiness was lower, than females, SS and SP after the exceptional lockdown measures. The reasons can reside in the more ordered lifestyle of PP in comparison to SS and SP, which mitigated the effects of the lockdown. Our results suggest that measures to improve sleep in females’ soc cer player should be adopted if these exceptional conditions will happen again.

Overhead squat assessment reflects treadmill running kinematics
ConclusionsOHSA was associated with some important and dysfunction-related hip, knee and ankle kinematics. Running coaches, may use OHSA as an assessment tool before the corrective training plan to detect injury-related compensation patterns to reduce the risk of injury and improve running technique.

Feasibility of delivering supervised exercise training following surgical resection and during adjuvant chemotherapy for pancreatic ductal adenocarcinoma (PRECISE): a case series
DiscussionThis case series provides preliminary evidence that concurrent exercise training during adjuvant therapy is safe, feasible and well tolerated, preventing an expected decline in functional fitness, muscular strength and health-related quality of life (HRQoL). Given the adverse effects of treatment, these findings are promising and provide further evidence for the inclusion of exercise training as a standard of care for surgical rehabilitation and managing treatment-related toxicities. Future research should explore the impact of exercise training during neoadjuvant chemotherapy, with prehabilitation now standard p...

Intrinsic variables associated with low back pain and lumbar spine injury in fast bowlers in cricket: a systematic review
ConclusionInconsistencies in results may be related to differences in study design, injury definitions, participant characteristics, measurement parameters, and statistical analyses. Low back pain and lumbar spine injury occurrence in fast bowlers remain high, and this may be due to an absence of low bias studies that have informed recommendations for their prevention. Future research should employ clearly defined injury outcomes, analyse continuous datasets, utilise models that better represent lumbar kinematics and kinetics during fast bowling, and better quantify previous injury, lumbar anatomical features and lumbar ma...

Athletes ’ experiences of using a self-directed psychological support, the BAck iN the Game (BANG) smartphone application, during rehabilitation for return to sports following anterior cruciate ligament reconstruction
ConclusionThe analysis of the interviews illustrates athletes ’ awareness in interacting with, and the challenging and supportive experiences of using the app. The BANG app might provide support for returning to sport, primarily psychological support, as an adjunct to regular physiotherapy-guided rehabilitation. Athletes’ experiences of the BANG app could be improved by healthcare professionals providing additional advice about when to use which content and why.Trial registrationClinicalTrials.gov, NCT03959215.

The effect of abdominal bracing on respiration during a lifting task: a cross-sectional study
ConclusionThis study demonstrated that abdominal bracing performed during a lifting task reduces lung volume despite an increase in diaphragmatic motion. Diaphragm excursions strongly correlate with lung volumes even under postural loading.Trial registrationThe study was prospectively registered on 8 April 2021 at ClinicalTrials.gov with identification number NCT04841109.

Rotational stability can be enhanced in revision anterior cruciate ligament reconstruction using the over-the-top augmentation technique compared to single bundle technique
ConclusionsOA-ACLR showed enhanced rotational stability with pivot shift test compared to SB-ACLR. It may be considered a useful alternative for revision ACL reconstruction. (Source: BMC Sports Science, Medicine and Rehabilitation)

The association between tibial torsion, knee flexion excursion and foot progression during gait in people with knee osteoarthritis: a cross-sectional study
ConclusionsBoth horizontal and frontal lower limb alignments were associated with knee flexion excursion at early stance of gait cycle in participants with medial knee OA. The distal rotational profile of lower limb would likely affect knee motion in sagittal plane. It implies that people with moderate knee OA could possibly benefit from correction of rotational alignment of lower limb. (Source: BMC Sports Science, Medicine and Rehabilitation)

A systematic review and net meta-analysis of the effects of different warm-up methods on the acute effects of lower limb explosive strength
ConclusionThe results of this review indicate that static stretching reduced explosive performance, while the 2 warm-up methods, namely dynamic stretching and static combined with dynamic stretching, were able to significantly improve explosive performance, with dynamic stretching being the most stable and moderated by multiple variables and dynamic stretching for 7 –10min producing the best explosive performance. In the future, high-quality studies should be added based on strict adherence to test specifications. (Source: BMC Sports Science, Medicine and Rehabilitation)

Effects of 36-hour recovery on marksmanship and hormone concentrations during strenuous winter military survival training
ConclusionA short recovery during a strenuous training can prevent the degradation in psychophysiological state and shooting performance in soldiers, which can be crucial for survival in demanding operational winter environment. In the present study, 36-h rest period during the field training seems to enhance recovery but the duration of the period was inadequate for full recovery from the accumulated operative stress. In conclusion, appropriate recovery periods should be implemented in order to optimize occupational performance during high operative stress. (Source: BMC Sports Science, Medicine and Rehabilitation)
