## 4 Discussion
It is likely that differences in results can be attributed to different vibration devices (side-alternating system versus linear motions) and specific vibration variables used (e.g., frequency and acceleration). [PERSON] et al. [35] also demonstrated no significant differences for bone biomarkers in a 10-week WBV exercise (30-40 Hz) program in overweight Latino boys. Coriander and/or WBV exercise had no effect on body mass, consistent with [25], who used an identical experimental design but in healthy young adult male rats. [PERSON] et al. [36] reported that body mass in WBV exercise mice did not change significantly during a six-week experiment period compared to sedentary controls and WBV + dehydroepiandrosterone (DHEA) treated mice. In addition, [PERSON] et al. [37] reported no significant differences in body mass between controls and WBV rats subjected to either a high-fat diet or normal diet. [PERSON] et al. [38] also showed no differences in body mass of middle-aged mice with or without a four-week WBV exercise regimen. On the other hand, [PERSON] et al. (2014) reported that after diabetes mellitus diagnosis, mass and body mass index increased rapidly, with the most rapid weight gain during the first two weeks in children and adolescents with T1 DM. In relation to coriander, [PERSON] et al. [6] found that daily oral administration for 30 days to obese-hyperglycemic-hyperlipidemic _Meriones shawi_ rats did not have any significant effect on body mass. Considering the food intake after four weeks in T1 DM rats subjected to the concomitant treatment, no differences were observed amongst the groups. This finding shows that DM influences the intake of these animals even in those submitted to WBV exercise. In our previous studies [25; 39] using the same concomitant protocol, although performed in healthy animals, we observed an increase in feed intake in the animals exposed to WBV exercise. Our present finding corroborates with [PERSON] et al. [36], which demonstrated that WBV exercise and/or DHEA supplementation did not alter food intake in mice. Despite coriander being used for the treatment of some gastrointestinal disorders, including diarrhea [40], we did not observe altered stool consistency. This could be due to malabsorption or pelvic nerve damage caused by diabetes peripheral neuropathy, which may increase bowel movement frequency [41], therefore minimizing the effect of coriander. [PERSON] et al. [25] demonstrated an alteration in stool consistency in healthy rats that consumed only coriander (and compared to other groups). The different health conditions of the animals reported ([40] and [25]) may explain the differential findings regarding stool consistency. Moreover, the findings in the current study corroborate those of [PERSON] et al. [39], who investigated the effect of WBV exercise and an aqueous extract of _Chenopodium ambrosioides_ in male Wistar rats. They also showed no alteration in stool consistency. The concomitant treatment proposed in the present study was not able to alter the metabolic outcome variables in animals with T1 DM as we expected. Factors such as the alloxan drug, as the model of DM chosen for this study, could be relevant to the differential results found, although our hypothesis was based on existing results in the literature about the effects of coriander on diabetes (both induced by streptozotocin and alloxan) and of WBV on the selected metabolic variables. Some limitations of the current study should be considered. For instance, only a limited number of hormones were measured, while others such as insulin were not investigated. An analysis of glycated hemoglobin (HbA1) would be interesting for the diagnosis of DM. Further, we only studied one specific vibration regime and it is possible that an intervention with a different vibration frequency, vibration magnitude, or vibration duration would have produced significant effects.
