    The combined effect of a muscle strength training program with the previous application of a topical menthol gel on the intensity of chronic low back pain (CLP) and the functional capacity of overweight/obese older women was evaluated. A randomized controlled clinical trial with parallel group comparison was conducted. In Phase 1 (12-weeks), 31 women were randomly assigned: (i) a control group that did not change their habits (CG; n = 11); (ii) group of strength training prior to application of a gel with menthol (RTM; n = 10) and (iii) group that performed the same training prior to application of a placebo gel (RTP; n = 10). After 12 weeks of no training, phase 2 of the study (32-week duration) was run, where the RTM and RTP women were randomly reassigned. It was evaluated before and after each phase: body composition, functional capacity, pain perception and Oswestry disability index. The significance level established for the study was p ≤ .05. Both training groups significantly improved all variables after stages 1 and 2, with significant post-intervention differences but no significant intergroup differences, although RTM obtained better results. The percentage of improvement in pain perception and functional parameters were related to the intervention time without positive effects for CG. In conclusion, the use of menthol gel prior to a muscle strength program reduced pain and enhanced the functional improvements achieved as a result of moderate-high intensity training in older adult women with CLP and overweight or obesity

    Purpose: The aim of this study was to evaluate the effects of aerobic exercise in combination with garlic and lemon on the lipid profile, metabolic parameters, and liver enzymes of obese male rats. Design: Sixty-four male Wistar rats were divided into eight equal groups consisting of 1) control following no treatment (n = 8); 2) hypercaloric fatty-food-based diet (n = 8); 3) aerobic exercise (AE, n = 8); 4) garlic intake (G, n = 8); 5) aerobic exercise with garlic intake (AEG, n = 8); 6) lemon intake (L, n = 8); 7) garlic and lemon (GL, n = 8); 8) garlic, lemon and aerobic exercise (GLAE, n = 8). After six weeks of intervention, blood samples were taken to obtain cholesterol, triglycerides (TG), high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), and glucose. C-reactive protein (CRP), alanine aminotransferase (GPT), aspartate aminotransferase (GOT), alkaline phosphatase (ALP), creatinine (Cr), urea and uric acid (UA) were also measured. A one-way ANOVA or the Kruskal Wallis tests for the non-normally distributed variables, with post-hoc pairwise comparisons were conducted to assess differences between groups. Results: All the intervention groups obtained significantly better values compared to the hypercaloric group, although being also fed with a hypercaloric diet. In certain parameters, the intervention groups obtained equal or even better results than the control healthy group. The combination of aerobic exercise with the intake of garlic and lemon showed slightly non-significant better results. Conclusion: Aerobic exercise combined with the intake of garlic and lemon juice may influence the lipid profile, liver enzymes, and other blood parameters associated with cardiovascular disease.The authors gratefully acknowledge the cooperation of the Shahrekord Medicinal Plants Research Center, which supported and funded this project
