Efeito do treinamento físico sobre o perfil metabólico e ósseo de ratos recém-desmamados

Introduction: The practice of moderate-intensity exercise can reduce the risk of infections and improve metabolic aspects of the person. Objective: To investigate the effects of aerobic physical training on endocrine and metabolic aspects, bone and immune system. Methods: Twenty Wistar rats were divided in two groups: sedentary (GS) and trained group (TG). Training program consisted in swimming, 6 weeks, supporting a workload corresponding to 5% of body weight. At the end of the experiment, were performed counting total and differential leukocyte count and hematocrit. After training period, were analyzed glucose, total protein, triglycerides, cholesterol, liver and muscle samples for the determination of the levels of glycogen, and determination of the tibia length and bone area. All dependent variables were analyzed by one-way analysis of variance (ANOVA) and a significance level of P < 0.05 was used for all comparisons. Results: Hematocrit (%) analyzed showed a significant difference, with higher values for TG (54.63 +/- 1.41) than for the GS (49.5 +/- 1.65). The total leukocyte count was not significantly different, as there was no difference in the differential count. Total cholesterol showed significant decrease in GT (GT = 68.27 +/- 13.71 mg/dL; GS = 94.44 +/- 28.09), the total protein levels also showed significant reduction (GT = 7.3 +/- 0,40 g/dL; GS = 7.74 +/- 0.36 g/dL) glucose levels and triglyceride showed no significant differences. The bone length showed a significant difference (GT = 40 +/- 0.14 mm; CG = 42.10 +/- 0.12mm). The tibial area showed the lowest value for the GT (1.53 +/- 0.12cm(2)) than for the GS (1.67 +/- 0.18cm(2)) however the difference was not statistically significant. Conclusion: It can be concluded that aerobic exercise training is able to produce some unique physiological changes in young rats. There is also the need to prescribe exercises that meet the particular maturational stage of development.

Efeitos do treinamento em natação sobre propriedades mecânicas e estruturais do fêmur de ratas ovariectomizadas

We investigated the effects of swimming training (ST) on femoral mechanical and structural properties in ovariectomized female rats. Female Wistar rats [age = 20 weeks; body weight (BW) = 271,42 +/- 17,6 g] were subjected to ovariectomy (OVX) or laparotomy (SHAM) and allocated to one of the following groups: swimming OVX (SO, n=12), control OVX (CO, n=12), swimming SHAM (SS, n=12) and control SHAM (CS, n=12). Fifteen days after surgery SO and SS groups were subjected to a ST (60 min/day, 5 days/week, overload of 3% of BW) for 10 weeks. Alkalin phosfatase was reduced in OVX as compared to SHAM (18,87 pg/mL vs. 53,93 pg/mL, respectively), but not altered by ST. Animals SHAM showed more cancellous bone than OVX (255,50 +/- 38,27 vs 288,75 +/- 39,63 points, respectively). Exercised animals exhibited more cancellous bone than controls (292,00 +/- 33,54 vs 251,54 +/- 38,99 points, respectively) in this region and in the grater trochanter (281,50 +/- 34,42 vs 237,23 +/- 53,03 points; respectively). Bone mineral density and cortical bone in the femur midshaft were not altered either by OVX or ST. The maximum force and thoughness of the femoral neck and midshaft were not affected either by OVX or ST. It was concluded that ST benefits cancellous bone mass in the femoral proximal region (i.e. femoral neck and greater trochanter), independently of ovariectomy, which did not reflect in improved mechanical properties either in the femoral neck or midshaft.

Efeito das cargas de treinamento sobre parâmetros fisiológicos de futebolistas

The aim of this study was to investigate the effects of three weeks of training with intensity monitored on the aerobic capacity of professional soccer players. Fourteen players, members of a first division Brazilian Championship team in 2010, aged 22.78 +/- 3.06 years were evaluated pre and post three weeks of training. The anaerobic threshold intensity LAn was determined by bi-segmented method, for this four submaximal efforts of 800 meters with intensities 10, 12, 14 and 16 km/h were applied. Thirty three training sessions were quantified in zones according to heart rate related to the LAn (FCLAn): Z1 - 10% below, Z2 - 90-100% and Z3 - above the FCLAn. During training participants remained 31.17 +/- 14.86%, 42.96% and 25.87 +/- 14.90 +/- 16.67% in Z1, Z2, and Z3 respectively. There were no significant differences in the LAn (pre = 13,29 +/- 0,71 km.h(-1); post = 12,85 +/- 0,90 km.h(-1)), perceived exertion (pre = 11,53 +/- 1,45 u.a; post = 11,23 +/- 1,53 u.a) and FCLAn (pre = 166,64 +/- 10,69 bpm; post = 174,50 +/- 10,89 bpm) between conditions before and after training, indicating that three weeks of training are insufficient to generate positive changes in soccer players LAn.
