The expansion of adipose tissue, characteristic of obesity, releases inflammatory cytokines, leading to metabolic disorders. Physical activity, on the other hand, promotes fat loss and changes inflammatory profile. This study aimed to investigate the associations of 20 gene variants (TLR2, TLR4, IL1B, IL6, NFKB1, TNF, NFKBIA, NLRC4, CARD8 and NEK7) with anthropometric and biochemical changes induced by physical exercise programs. Thus, 58 children and adolescents participated of the 12-week exercise programs. Parameters were collected before and after programs: body mass index, body fat percentage, LDL-C, HDL-C, triglycerides, total cholesterol, insulin, glucose, HOMA-IR and QUICKI. Changes in these parameters were calculated (final - initial measurements) for subsequent analyses. Linear regression analyses were performed to investigate associations between genotypes and changes in the analyzed parameters. We found associations between 14 variants in nine genes with anthropometrical and biochemical outcomes. Observing the distribution of the sample, the groups of individuals who responded less in relation to body fat and TG levels concentrated the highest scores of polygenic indexes as a result of a greater number of risk variants. In conclusion, some genotypes related to the inflammatory profile provided less favorable anthropometrical and biochemical outcomes in response to physical exercise programs.

Postcancer rehabilitation: multidisciplinary exercise - programme organisation and feasibility.
BMJ Support Palliat Care

Université de Franche-Comté, UMR 1098, Besancon, France.
Background: Although the benefit of supportive care in the postcancer period is now well demonstrated, its implementation in the patient journey remains challenging. This article describes the development, since 2015 and in routine care, of supportive postcancer care comprising a multidisciplinary rehabilitation programme (MRP) based on exercise for patients with early breast cancer.
Methods: As part of quality control, we reviewed all patient files since the programme was implemented.
Comparative Effects of the Free Weights and Smith Machine Squat and Bench Press: The Important Role of Specificity for Strength Adaptations.
Int J Sports Physiol Perform

Purpose: Although previous studies have compared strength-training adaptations between free weights (FW) and machine-guided exercises, those studies did not use a Smith machine (SM), which most closely replicates the exercises performed with FW. Thus, the aim of the present study was to investigate the chronic effects of strength-focused, velocity-based training regimens using FW versus SM.
Methods: Thirty-seven sport-science students (14 female) were assigned, balanced by sex and relative strength, to either an FW or SM training group.

Background: Older adults experience chronic inflammation, which is associated with health conditions such as sarcopenia, and resulting in reduced functional capacity. Resistance training (RT) is a beneficial intervention for improving health in the elderly.
Objective: This study aimed to investigate the effect of RT on inflammatory biomarkers, body composition, and functional capacity in healthy adults aged 60 years and over.

Background: Sedentary lifestyles, poor nutritional choices, inadequate sleep, risky substance use, limited social connections, and high stress contribute to the growing prevalence of chronic diseases. Lifestyle medicine, emphasizing therapeutic lifestyle changes for prevention and treatment, has demonstrated effectiveness but remains underutilized in clinical settings. The Complete Lifestyle Medicine Intervention Program-Ontario (CLIP-ON) was developed to educate the rural population of Northern Ontario in lifestyle medicine to improve health outcomes and engagement.
