Leukocyte-Rich and Leukocyte-Poor Platelet-Rich Plasma in Rotator Cuff Repair: A Meta-analysis
In conclusion, leukocyte-poor platelet-rich plasma can improved the clinical function and reduced retear rate in arthroscopic rotator cuff repair. In contrast, the efficacy of leukocyte-rich platelet-rich plasma was not significantly improved with the exception of VAS score [...] Georg Thieme Verlag KG Rüdigerstraße 14, 70469 Stuttgart, GermanyArticle in Thieme eJournals: Table of contents  |  Abstract (Source: International Journal of Sports Medicine)

Reply to the Letter to the Editor from Dr. Seet-Lee and Colleagues
Int J Sports Med 2022; 43: 288-288 DOI: 10.1055/a-1754-3377The authors would like to thank Dr. Seet-Lee and colleagues for their comments on our recently-published manuscript in the International Journal of Sports Medicine 1. Dr. Seet-Lee and colleagues highlighted some inadequacies, specifically when using mean difference or raw mean difference as effect measure. However, when evaluating blood vessel density by different reliable and validated histological procedures, would it be wrong to assume, as we did, that all the obtained measurements from different ...

Letter to the Editor on: “The Effects of Physical Exercise on Tumor Vasculature: Systematic Review and Meta-Analysis.”
Int J Sports Med 2022; 43: 286-287 DOI: 10.1055/a-1754-3323Dear Editor,We read with interest the recent article “The Effects of Physical Exercise on Tumor Vasculature: Systematic Review and Meta-analysis” 1 and after careful appraisal and consideration we feel that some aspects of the data and analysis warrant further review. The study reported some promising results, namely that both chronic and acute exercise appear to improve intratumoral vascularisation in animal models. This is an important finding given increased vascularisation through tumor modulation may have t...

Influence of the Weekly and Match-play Load on Muscle Injury in Professional Football Players
Int J Sports Med DOI: 10.1055/a-1533-2110The aim of this investigation was to examine the impact of the weekly training load and the match running patterns prior to a muscle injury as potential risk factors of muscle injury in professional football players. Forty male professional football players participated in the investigation. Running distances at different intensities 5 min and 15 min prior to the injury were compared to the same time-points in official matches of the same player with no injury events. Furthermore, the cummulative session ratin...

Effect of 12-wk Training in Ovariectomised Rats on PGC-1 α, NRF-1 and Energy Substrates
Int J Sports Med DOI: 10.1055/a-1717-1693Metabolic diseases are associated with hypoestrogenism owing to their lower energy expenditure and consequent imbalance. Physical training promotes energy expenditure through PGC-1α and NRF-1, which are muscle proteins of the oxidative metabolism. However, the influence of physical training on protein expression in individuals with hypoestrogenism remains uncertain. Thus, the aim of this study is to determine the effect of 12 weeks of moderate-intensity swimming training on the muscle expression of PGC-1α, NRF-1, glycogen...

Maximal Aerobic Power Using the Modified Heck Protocol: Prediction Models
Int J Sports Med DOI: 10.1055/a-1749-5829The purpose of this study was to develop prediction models based on an incremental treadmill test to volitional exhaustion utilizing the modified Heck protocol. A total of 598 professional and youth athletes participating in different sports were recruited for this study. Specifically, the study enrolled professional male soccer players (n=380), professional male futsal players (n=24), elite male basketball players (n=27), professional male soccer referees (n=50), elite female soccer players (n=19), youth male bas...

Effects of Flat and Uphill Cycling on the Power-duration Relationship
Int J Sports Med DOI: 10.1055/a-1749-5884The purpose of this study was to investigate the effects of flat and uphill cycling on critical power and the work available above critical power. Thirteen well-trained endurance athletes performed three prediction trials of 10-, 4- and 1-min in both flat (0.6%) and uphill (9.8%) cycling conditions on two separate days. Critical power and the work available above critical power were estimated using various mathematical models. The best individual fit was used for further statistical analyses. Paired t-tests and Bland-Altman...

Effect of Fatigue and Graded Running on Kinematics and Kinetics Parameters in Triathletes
This study aimed to evaluate the effect of cycling-induced fatigue on subsequent running with different ground inclinations on triathletes. Twenty male triathletes ran on a treadmill at individual speeds, on three inclines: level (0%), 7% uphill (7%), and 7% downhill (−7%). Subsequently, the athletes performed an incremental ramp-to-exhaustion (RTE) protocol on an ergometric bicycle until task failure and repeated the running protocol (POST-RTE). During running and cycling was monitored perceived exertion (RPE) and heart rate (HR). Plantar pressure ...

Impact Attenuation and Deformation Characteristics of Dance Floors on Jump Kinematics
Int J Sports Med DOI: 10.1055/a-1766-0056Specialist dance floors have been promoted to reduce impact forces and reduce lower limb injury for dancers. 18 trained female dancers carried out 70 continuous ballet jumps on 4 different surfaces wearing an XSENS suit. Three specialist dance floors, Floor A (64% force reduction), Floor B (67% force reduction), Floor C (no data) were compared to Floor D (vinyl-covered concrete - control). Dependent variables for each analysed jump (2,3,4, and 67,68,69) were ankle, knee, hip range of movement (ROM); lower and uppe...

The Aging Athlete: Paradigm of Healthy Aging
Int J Sports Med DOI: 10.1055/a-1761-8481The Exercise Boom of the 1970’s resulted in the adoption of habitual exercise in a significant portion of the population. Many of these individuals are defying the cultural norms by remaining physically active and competing at a high level in their later years. The juxtaposition between masters athletes and non-exercisers demonstrate the importance of remaining physically active throughout the lifespan on physiological systems related to healthspan (years of healthy living). This includes ~50% improved maximal aerobic ...

Association of Cardiopulmonary Exercise Capacity and Adipokines in the General Population
Int J Sports Med DOI: 10.1055/a-1699-2380Adipokines and cardiorespiratory fitness (CRF) are associated with the (patho)physiology of cardiometabolic diseases. Whether CRF and adipokines are related is unclear. We investigated associations of CRF with leptin, adiponectin, chemerin, resistin and vaspin. Data from the population-based Study of Health in Pomerania was used (n=1,479; median age 49 years; 51% women). Cardiopulmonary exercise testing was used to measure CRF. Circulating adipokine concentrations were measured by enzyme-linked immunosorbent assay...

Comparison between DXA and MRI for the Visceral Fat Assessment in Athletes
In conclusion, VAT volumes derived from DXA were larger and significantly correlated with those derived from MRI across a wide range of values. Methods using DXA for assessing the visceral fat volume may require adjustment to estimate abdominal visceral fat volume in athletes, with care taken when using such methods for heavyweight athletes.

Efficacy of repair for ACL injury: a meta ‑analysis of randomized controlled trials
Int J Sports Med DOI: 10.1055/a-1755-4925We aim to compare the curative effect of primary repair for anterior cruciate ligament (ACL) injury with reconstruction and provide the reliable evidence for its clinical application. The literatures were searched in PubMed, EMBASE, Springer, and other medical literature databases published between January 1970 and June 2021. Basic characteristics, surgery technique, clinical outcome scores and physical examination results were recorded and evaluated. Seven randomized controlled trials (RCT) were eligible for inclusion. The results showed that there were no statistically significant...
