Objective The purpose of this study was to investigate the effects of aerobic exercise on PKC/CaV1.2 pathway in mesenteric arterial smooth muscle from spontaneously hypertensive rats (SHRs) Methods Twelve-week-old male normotensive Wistar–Kyoto (WKY) rats and SHRs were randomly assigned to sedentary groups (SHR-SED, WKY-SED) and exercise training groups (SHR-EX, WKY-EX). Exercise groups were performed an 8-week moderate-intensity treadmill running. After 8 weeks, vascular contractility of mesenteric arteries was measured. Vascular smooth muscle cells (VSMCs) were obtained with an enzymatic isolation method. CaV1.2 channel currents were examined by using whole-cell patch clamp recording technique. Results 1) Body weight and systolic blood pressure (SBP) in both WKY-EX and SHR-EX were significantly lower than those of their sedentary counterparts (both P＜0.05). Body weight in SHR-SED was remarkably lower than WKY-SED (P＜0.05), while SBP was much higher than WKY-SED (P＜0.05). 2) PDBu (PKC activator) elicited a tension increase, and Gö6976 (PKC inhibitor) induced vasodilation. Both the responses of PDBu and Gö6976 in SHR-SED were notably increased compared with WKY-SED (both P＜0.05), however, exercise training significantly suppressed these increases (both P＜0.05). 3) Nifedipine (CaV1.2 inhibitor) induced vasodilation. Response to nifedipine in SHR-SED was more sensitive than both SHR-EX and WKY-SED (both P＜0.05). 4). The current density of SHR-SED and WKY-EX exhibited an increase compared to the WKY-SED (both P＜0.05), and the current density of the SHR-EX decreased obviously in contrast with SHR-SED (P＜0.05). Besides, PDBu enlarged current density of all the groups, while Gö6976 decreased current density. The increase or decrease amplitude in SHR-SED was significantly higher than WKY-SED (both P＜0.05), whereas exercise training markedly inhibited those responses (both P＜0.05). Conclusions Aerobic exercise efficiently prevents the upregulation of PKC/CaV1.2 pathway in hypertension, and enhances the function of vascular smooth muscle.

Objective To study the effect of different time of electrical stimulation on C2C12 myotubes function, and further explore its molecular mechanism. Methods An electrical stimulation was given 7 days after C2C12 myotubes differentiation, of which intensity was 30ms, 3Hz, and the stimulation time was 60mins, 120mins, and 180mins, respectively. A total of four experimental groups, including Con (control group), E60 (60 mins group), E120and E180. Microscope was used to observe the muscular myotubes form; Kits were to detect MDA and ROS; Western blot was used to detect the expression of autophagy proteins and mechanism proteins, including PGC1, p-ULK, SIRT1 and SIRT3. Results Compared with the control group, MDA, ROS, SIRT3 increased significantly in E60 (p<0.05), p-ULK and PGC1 increased significantly (p<0.01), SIRT1 decreased significantly (p<0.05). In E120, MDA、ROS、SIRT3 and PGC1 increased significantly (p<0.01), SOD decreased significantly (p<0.05). In E180, MDA and ROS increased significantly (p<0.01), SOD decreased significantly (p<0.01). Conclusions Moderate electrical stimulation can significantly activate oxidative stress, and further promote SIRT3, PGC1 and p-ULK expression, while excessive stimulation has the opposite effects.

Objective Aerobic capacity is a quantitative predictor of the morbidity and mortality in many diverse patient populations. While aging is the main factor affecting aerobic capacity. The present study aimed to assess the effect of aerobic capacity and aging on metabolic profile in rats and to investigate the metabolic interactions between white adipose tissue (WAT), muscle and serum. Methods In this study, we used rat models that were selectively bred to differ in maximal running capacity (High capacity runners (HCR) and Low capacity runners (LCR)). Part of the rats were sacrificed after 9 months and the rest at 21 months. The effect of aerobic capacity on metabolic profile was assessed from 9 months old young rats (HCR-Y and LCR-Y), while the effect of aging on the metabolic profile in different capacity rats was determined comparing 9 months to 21 months old rats (HCR-O and LCR-O). Nuclear magnetic resonance (NMR) spectroscopy was performed to detect the metabolomics of WAT, muscle and serum. Partial least-squares-discriminant analysis (PLS-DA) was used for pattern recognition between HCR-Y and LCR-Y and between HCR-O and LCR-O. Metabolites with variable influence on projection (VIP) >1.0 and p<0.05 were classified as significantly different metabolites between groups. Spearman correlation was used to assess the metabolic interactions between white adipose tissue (WAT), muscle and serum. Results HCR-Y rats had significantly higher skeletal muscle mass-to-body mass ratio (p<0.001), while lower body mass (p<0.001), fat mass (p<0.001), skeletal muscle mass (p=0.035) and fat mass to body mass ratio (p=0.004) than LCR-Y rats. The running capacity of HCR-Y rats was 132.7% (best running speed) better than LCR-Y rats (p<0.001). However, with age, the difference between body compositions between the two capacity groups became insignificant. HCR-O only had significantly lower body mass than the LCR-O (p=0.02). Running capacity (p=0.06) was 86.4% (best running speed) higher in the HCR-O rats than that of the LCR-O rats. PLS-DA revealed marked effects of aerobic capacity on metabolic profile in all three tissue types between HCR-Y and LCR-Y. The metabolic profile classification and prediction was best (i.e. sharper) in muscle than in WAT and serum. In addition, muscle and serum contained more significantly different metabolites than WAT in HCR-Y than in LCR-Y. Pathway analysis of the significantly different metabolites between HCR-Y and LCR-Y revealed that all the pathways belong to the lipid metabolism and amino acid metabolism in muscle while in serum it is only amino acid metabolism. However, in the case of the old groups, the PLS-DA gave reversed results. It revealed that WAT performed best in terms of classification and prediction of metabolites between HCR-O and LCR-O and had the most significantly different metabolites out of the three tissue types. The significantly different metabolites’ pathways belong to lipid metabolism in WAT. When assessing

Objective The individualized training intensity is important in the prevention of overweight and obesity. Our study compared heart rate (HR), oxygen uptake (VO2), and work load (WL) corresponded to the anaerobic threshold during an incremental cycling test between ventilatory (VT) and heart rate variability threshold (HRVT) methods. Further, we examined the validity of three heart rate variability analyses to assess VT in overweight young men. Methods Sixteen overweight young men (age 21.1±1.7 years, height 175.3±5.5 cm, weight 84.0±6.7kg, body mass index 27.3±1.2 kg/m2, VO2peak33.6±4.3ml/min/kg ) performed a gradual exercise test on a cycle ergometer (Lode Corival，Lode B.V.，Groningen，Newtherlands).The protocol started at 30 W for 2 minutes with subsequent increments of 30 W every 2 minutes until exhaustion. During test, gas exchanges (VO2, VCO2) and ventilation (VE) were measured by breath-by-breath using Metamax 3B portable analyzer (CORTEX, Biophysik GmbH，Leipzig，Germany). The ventilatory threshold (VT) was identified as the point at which VE for O2 began to rise without a concomitant rise in ventilator equivalent for CO2. The R-R intervals were continuously recorded using a Polar RS800cx HR monitor(Kempele, Finland). HRV data were further analyzed by Kubios HRV analysis software (Kuopio, Finland) based on time-domain (RMSSD) , Poincare plots(SD1) and time-varying spectral (fHF×HFP) methods. Data were analyzed using SPSS 22.0. Normal distribution of variables was verified by Kolmogorov-Smirnov test. The relationship between HRVT variables and VT was assessed using paired t-test and Pearson’s production correlation. The magnitude of concordance between the methods was further evaluated by Bland-Altman plots. Results No significant difference was witnessed in HR, VO2, and WL related to AT between HRVT and VT methods（P<0.05）. The relationships were found between the methods to determine the AT for all variables analyzed (r=0.40-0.91). Additionally, the Bland-Altman plots revealed that findings showing narrow limits of agreement present for fHF×HFP and the VT whilst the association between RMSSD, SD1 and VT showed wider limits. Conclusions The estimation of the HRVT, especially derived through the time-varying spectral (fHF×HFP), may be a noninvasive and more robust method to determine the VT, which could be used to adapt individualized training intensity to overweight young men for training prescription.

Objective The objectives were to analyze the body composition and body functions of the freestyle ski half-pipe national team athletes, to understand the body composition characteristics of the athletes , and to explore the relationship between body composition and body function in the sports program, in preparation for 2022 The Winter Olympics provides a theoretical reference. Methods 9 members of the freestyle ski half-pipe national team were used as subjects (average age 15.78±0.97, exercise age 6.38±2.75), and they were tested and analyzed using an ultrasonic body composition tester and Wingate anaerobic power bike. Body composition test indicators: body fat rate, lean body mass. Body function test indicators: maximum anaerobic power. This paper uses literature, experimental and mathematical statistics. And the mathematical statistics method: using SPSS 2.0 to analyze the data by Pearson correlation. Results 1. The body fat rate of male and female athletes in freestyle half-pipe national team was: 7.60±1.16; 19.75±1.25. The lean body mass of male and female athletes was: 53.8±1.85KG; 44.75±0.62KG. The maximum anaerobic power of male and female athletes in freestyle half-pipe national team was: 453.80±17.87; 345.50±3.01. The lean body mass of male athletes was significantly positively correlated with the maximum anaerobic power (r=0.995, P<0.01). Female athletes' lean body mass was positively correlated with maximum anaerobic power, but not significant. There is no correlation between the body fat rate and the maximum anaerobic power of male and female athletes in the freestyle ski half-pipe national team. Conclusions 1. Freestyle ski half-pipe players have a positive correlation between lean body mass and anaerobic capacity. According to the characteristics of the sports program, the higher lean body weight has a positive impact on improving the athletic ability and thus ensuring the completion of difficult movements. 2. Due to the relationship between athletes' age and sample size, the data in this paper is only a recommended reference for this sports program. It is not applicable to all programs. It is necessary to continue to supplement the data to establish a body composition evaluation system for the freestyle ski half-pipe team.
