          Abstract

          This article has been retracted by Hindawi following an investigation undertaken by the publisher [1]. This investigation has uncovered evidence of one or more of the following indicators of systematic manipulation of the publication process: Discrepancies in scope Discrepancies in the description of the research reported Discrepancies between the availability of data and the research described Inappropriate citations Incoherent, meaningless and/or irrelevant content included in the article Peer-review manipulation The presence of these indicators undermines our confidence in the integrity of the article's content and we cannot, therefore, vouch for its reliability. Please note that this notice is intended solely to alert readers that the content of this article is unreliable. We have not investigated whether authors were aware of or involved in the systematic manipulation of the publication process. In addition, our investigation has also shown that one or more of the following human-subject reporting requirements has not been met in this article: ethical approval by an Institutional Review Board (IRB) committee or equivalent, patient/participant consent to participate, and/or agreement to publish patient/participant details (where relevant). Wiley and Hindawi regrets that the usual quality checks did not identify these issues before publication and have since put additional measures in place to safeguard research integrity. We wish to credit our own Research Integrity and Research Publishing teams and anonymous and named external researchers and research integrity experts for contributing to this investigation. The corresponding author, as the representative of all authors, has been given the opportunity to register their agreement or disagreement to this retraction. We have kept a record of any response received.

          Magnetic Resonance Imaging Assessment of Fatigue Injury during Exercise

          In order to investigate the changes of temporal function metabolism of lumbar and back muscles after exercise, a magnetic resonance imaging- (MRI-) based assessment of fatigue injury during exercise was proposed. A total of 100 healthy adult volunteers were selected, including 48 males and 52 females, aged from 19 to 30 years, with an average age of 24.8 + 2.3 years. They were divided into four groups according to the different time points of 0, 15, 30, and 45 minutes after exercise, with 25 persons in each group. PHILIPS Achieva 3.0 T Tx MRI scanner was used to perform BOLD and T2-mapping before and after exercise in four groups of healthy volunteers. All data were analyzed by statistical software. The results showed that the total CSA of the dorsi extensor muscle group and the CSA value of the dorsi extensor muscle group at different levels at different time points before and after exercise increased slowly in exercise period and decreased rapidly in recovery period. It was verified that BOLD MRI and T2-mapping imaging can indirectly evaluate the trend of CSA water metabolism and blood oxygen level in healthy adults after exercise.
