The aim of this study was to propose a standardization model of physical conditioning for diabetic rats from the classification of the intensity of the exercise in levels of speed training. Twenty-four male Wistar rats (229.92 ± 28.13 g, 95.08 ± 9.04 mg·dL-1) were divided into 4 groups: (a) Sedentary Diabetic Group (SDG); (b) Diabetic Group Treadmill (DGT); (c) Sedentary Control Group (SCG); and (d) Control Group Treadmill (CGT). The standardization of physical fitness was classified by exercise intensity (very light, mild, moderate, intense, very intense, and maximum) during the treadmill maximum stress test (TEM The animals of the DGT and CGT were submitted to exercise on treadmill, 1 hr·d-1 5 d·wk-1 for 5 wks under moderate intensity reassessed TEM 48 hrs after the last exercise session. After 12 days of induction of diabetes, the physical conditioning of diabetic and healthy rats was standardized at 19.58 ± 4.15 m·min-1, verified after 5 wks of physical fitness training increase in the DGT vs. SDG (P = 0.006) and reduction of DGT vs. CGT (P = 0.049). The findings indicate that the standardization of exercise intensity in diabetic rats under moderate intensity was adequate for the gain in physical fitness similar to healthy animals.

The aim of this study was to evaluate the effects of a CrossFit® session on hemodynamic indicators. Ten males between 18 and 35 yrs of age with at least 12 months of experience in CrossFit® participated in this study. The Treatment consisted of a single CrossFit® Session during which the subjects performed the EMOM (Every Minute On the Minute). The Control Session consisted of traditional bodybuilding (4 sets of 10 reps of leg press and 4 sets of 10 reps of bench press with rest between the 2 min series). Both Sessions were separated by 72 hrs of rest. Compared to the Control Session responses, the findings indicate significant differences in SBP soon after the CrossFit® intervention (P=0.002) and 40 min later (P=0.021), significant differences (P = 0.042) in DBP 40 min after the CrossFit® intervention, and significant difference in MAP 40 min after the Crossfit® intervention (P=0.004). The findings indicate that it is reasonable to conclude that the dose-response curve of the exercise in hypertensive patients may be decreased starting with the first session, which will empower the result of the current study in relation to the hypotensive effect of Crossfit® in a single session.

The aim of this study was to compare variables related to asymmetry, peak torque, and fatigue index in the Traditional strength training method and the Kaatsu strength training method, which is a blood flow restriction training strategy. Ten male subjects with a minimum of 12 months' experience in strength training participated in this study. It was found that while the Kaatsu method resulted in a greater loss of peak torque, its recovery was better at 24 and 48 hrs after the intervention with a higher peak torque peak versus the Traditional method. In addition, it was found that soon after the intervention, the Kaatsu method had a higher fatigue index and a greater asymmetry versus the Traditional method. The findings indicate that the Kaatsu training method promoted an increase in the concentration levels of CK, LDH, and lactate besides presenting higher values of fatigue index, and peak torque.

The purpose of this study was to compare the effects of a traditional strength training exercise, a training tether made of rubber attached to a belt around the swimmer's waist in the water, and training only in the water without additional strength training on the performance of the 25 m and 50 m freestyle in young athletes. The subjects consisted of 24 male athletes 15 to 16 yrs of age. They were divided into 3 groups: (a) 7 swimmers tethered by a rubber device while in the water (RW); (b) 7 swimmers who did strength training (ST) program; and (c) 7 swimmers who comprised the control group (CG). The findings indicate that there was no difference in the post-test responses between the group that trained while tethered to the rubber device and the group that engaged in a traditional strength training program. But, there were differences in both groups that engaged in strength training compared to the control group at both time points (pre- and post-test). Hence, it is reasonable to conclude that both strength training methods used in this study tended to promote improvements in speed, especially for shorter distances. [ABSTRACT FROM AUTHOR]

Analysis of the Response of Blood Lactate, Blood Glucose, Peripheral Oxygen Saturation, and Heart Rate during the Trail Running Competition. JEPonline 2016;19(2):27-33. This study evaluated the response of blood lactate, HR, SpO2, and blood glucose levels during a competition in different pathways (5km and 21km) and different levels of difficulty. This study included 20 male volunteer runners who were enrolled in the trail running k21 test series, Aracaju step - SE held at Serra Itabaiana National Park. The subjects were divided into two groups according to the conducted tour: Group 5km (G5km, n = 10); and Group 21km (G21km, n = 10). There was a significant difference in all variables in both modalities, in particular, lactate 5km vs. post 21km (P ). The findings indicate that the test 5km turned out to be much more intense with an increase in blood lactate level in relation to the test of 21km. [ABSTRACT FROM AUTHOR]
