    CONTEXT: Stigmatizing language or non-person-centered language (non-PCL) has been shown to impact patients negatively, especially in the case of obesity. This has led many associations, such as the American Medical Association (AMA) and the International Committee of Medical Journal Editors (ICMJE), to enact guidelines prohibiting the use of stigmatizing language in medical research. In 2018, the AMA adopted person-centered language (PCL) guidelines, including a specific obesity amendment to which all researchers should adhere. However, little research has been conducted to determine if these guidelines are being followed. OBJECTIVES: Our primary objective was to determine if PCL guidelines specific to obesity have been properly followed in the sports medicine journals that are interacted with most frequently. METHODS: We searched within PubMed for obesity-related articles between 2019 and 2022 published in the top 10 most-interacted sports medicine journals based on Google Metrics data. A predetermined list of stigmatizing and non-PCL terms/language was searched within each article. RESULTS: A total of 198 articles were sampled, of which 58.6 % were found to be not compliant with PCL guidelines. The most common non-PCL terms were "obese" utilized in 49.5 % of articles, followed by "overweight" as the next most common stigmatizing term at 40.4 %. Stigmatizing labels such as "heavy, heavier, heaviness," "fat" as an adjective, and "morbid" appeared in articles but at a lower rate. CONCLUSIONS: Our study shows that there is a severe lack of adherence to PCL guidelines in the most-interacted sports medicine journals. Negative associations between stigmatizing language and individuals with obesity will only persist if a greater effort is not made to change this. All journals, including the most prestigious ones, should adopt and execute PCL guidelines to prevent the spread of demeaning language in the medical community.

    PURPOSE: The purpose of this study was to assess the effects of 14 wk of chromium picolinate supplementation during the final 16 wk of a preseason resistance and conditioning program on body composition and neuromuscular performance in NCAA Division I wrestlers. During this phase of training, wrestlers are primarily interested in trying to improve physical performance and wrestling technique and are not engaged in severe, acute weight loss practices commonly employed before competition. METHODS: This double-blinded, randomized placebo-controlled study involved 20 wrestlers from the University of Oklahoma assigned to either a treatment group (Cr+3; N = 7; 20.4 yr +/- 0.1) receiving 200 micrograms chromium picolinate daily, a placebo group (P; N = 7; 19.9 yr +/- 0.2), or a control group (C; N = 6; 20.2 yr +/- 0.1) using a stratified random sampling technique based on weight classification. Body composition, neuromuscular performance, metabolic performance, and serum insulin and glucose were measured before and immediately following the supplementation and training period. RESULTS: Repeated measures ANOVA indicated no significant changes in body composition for any of the groups. Aerobic power increased significantly (P < 0.002) in all groups, independent of supplementation. There were significant trial and group x trial interactions for upper body endurance (P = 0.038) and relative bench press power (P = 0.050). Post-hoc analyses revealed that the C group increased upper body endurance (P = 0.006), but none of the pre- to post-test changes in bench press power were significant. CONCLUSIONS: These results suggest that chromium picolinate supplementation coupled with a typical preseason training program does not enhance body composition or performance variables beyond improvements seen with training alone.
