Long-term high-intensity training can cause a decline in immune function in athletes. In this study, we have explored whether bovine colostrum could improve the immune function in athletes undergoing intensive training. Thirty professional athletes were randomly divided into control group and bovine colostrum group; both groups received one month of intensive training. The control group received usual colostrum-free diet and the bovine colostrum group was fed bovine colostrum-rich milk every day. The venous blood was collected from both groups before and after the treatment period. The results showed that the lymphocyte population increased significantly in the bovine colostrum group compared to the control group (P < 0.05). There was no significant change in CD4+ and CD8+ in the two groups (P < 0.05), but the CD3+ and CD4+/CD8+ of the bovine colostrum group were significantly higher than those of the control group. There were significant differences in albumin, globulin and albumin/globulin ratio in the control group (P < 0.05), but not in the bovine colostrum group after training. The bovine colostrum group had lower serum albumin and albumin/globulin (P < 0.05) and higher globulin (P < 0.05) compared to the control group. There was no significant difference in immunologic indexes before and after training in both groups (P > 0.05). The decline in the markers of immune function after high-intensity training was ameliorated by the intake of bovine colostrum.

Background and aims: Intermuscular lipolysis disorder plays an important role in insulin resistance and diabetes mellitus and perilipin PLIN5 and PLIN3 are the key proteins in regulating muscle cellular lipolysis. Therefore, the purpose of this study was to examine the relationship between the expression of PLIN3 and PLIN5 protein following endurance training in streptozotocin (STZ) rats. Methods: A number of 24 male Wistar rats were randomly divided into low endurance training group (n = 8), high-intensity training group (n = 8), and control group (n = 8). Diabetes was induced in every rat by STZ injection. Three days after injection, the blood samples were taken from the cut tip of the tails of the mice and animals with blood glucose greater than 300 mg/dL were considered diabetic. The training program included eight weeks of aerobic training at different intensities. Training in high- and low-intensity groups included 22-25 and 5-8 m/min of training. Finally, one-way analysis of variance (ANOVA) and correlation was used to determine the significance of the differences between variables, followed by utilizing Tukey’s post-hoc test for significance. Results: The comparison between the groups by ANOVA showed significant differences in PLIN3 (P=0.0006) and PLIN5 (P=0.012). The results of Tukey post hoc test also demonstrated a statistical difference between the mean values of diabetic control group and high-intensity endurance group regarding PLIN3 (P=0.01) and PLIN5 (P=0.009), but no significant increase was observed in the lowintensity exercise group as compared to the control group (PLIN3, P=0.067 & PLIN5, P=0.44). As regards insulin resistance, there was a significant difference among the three groups (P=0.0001). Eventually, the result of the correlation between PLIN3 and PLIN5 showed similar enhancement by increasing the intensity (P=0.0026). Conclusion: According to research results, high-intensity endurance training increased the expression of PLIN3 and PLIN5 in diabetic specimens and PLIN3 and PLIN5 followed a similar increase pattern in high-intensity training

ABSTRACT At present, many studies have proved that proper exercise can promote the immune function of human body to a certain extent, but athletes need a lot of high-intensity sports training, and their immune function declines instead of improving. In order to control the decline of immune function of athletes after high-intensity training, this study propose the Zhenqi Fuzheng capsule to achieve this goal. Through experimental comparison, the parameters such as white blood cell content, immunoglobulin number, T lymphocyte, human hemoglobin content and exercise exhaustion time were detected after high-intensity training. The results showed that compared with the control group taking Zhenqi Fuzheng, the weight of those who had taken qifuzhengs capsule did not change, and the content of white blood cells, immunoglobulin, hemoglobin content and exercise time increased to a certain extent. The results showed that Zhenqi Fuzheng could inhibit the decrease of body immune function after high-intensity exercise, then accelerate the recovery of human immune function. This study is expected to enhance the immunity of sports athletes, and reduce athletes’ pain after high-intensity training.

Abstract Objective: This study aimed to analyze the effects of resuming training using yoga on the physical functions and fitness of Taekwondo athletes after high-intensity training.Method: A total of 50 Taekwondo athletes from this college were randomly divided into 2 groups. 25 athletes are in the control group, and they massage their muscles after high-intensity training to help recovery. Meanwhile, 25 athletes are in observation groups, and they practice yoga after high-intensity training for resuming training. After 8 weeks, the physical functions and fitness of the two groups of athletes were compared.Result: There was no statistically significant difference between the observation group and the control group before starting high-intensity training from 1st week to 8th week (P<0.05). From the 4th week to the 8th week after high-intensity training, the observation group's heart rate, heart rate after resuming training and subjective physical sensation degree scores were lower than the control group (P<0.05). After 8 weeks of resuming training in the observation group, hemoglobin was higher than the control group, blood urea nitrogen and creatine kinase was lower than the control group (P<0.05). The observation group's flexion test results of the sitting position after 4th week and 8th week of resuming training were higher than those of the control group (P<0.05).Conclusion: The use of yoga for resuming training after high-intensity training can improve the physical function and fitness of Taekwondo athletes, improve the flexibility of athletes and promote their professional skills.

To evaluate the effect of intermittent sprint training on sarcoplasmic reticulum (SR) function, nine young men performed a 5 wk high-intensity intermittent bicycle training, and six served as controls. SR function was evaluated from resting vastus lateralis muscle biopsies, before and after the training period. Intermittent sprint performance (ten 8-s all-out periods alternating with 32-s recovery) was enhanced 12% ( P < 0.01) after training. The 5-wk sprint training induced a significantly higher ( P < 0.05) peak rate of AgNO3-stimulated Ca2+ release from 709 (range 560–877; before) to 774 (596–977) arbitrary units Ca2+ ⋅ g protein− 1 ⋅ min− 1(after). The relative SR density of functional ryanodine receptors (RyR) remained unchanged after training; there was, however, a 48% ( P < 0.05) increase in total number of RyR. No significant differences in Ca2+ uptake rate and Ca2+-ATPase capacity were observed following the training, despite that the relative density of Ca2+-ATPase isoforms SERCA1 and SERCA2 had increased 41% and 55%, respectively ( P < 0.05). These data suggest that high-intensity training induces an enhanced peak SR Ca2+ release, due to an enhanced total volume of SR, whereas SR Ca2+ sequestration function is not altered.

Background: High-intensity training is comprised of sprint interval training (SIT) and high-intensity interval training (HIIT). This study compared high-intensity training with moderate-intensity continuous training (MICT) on cardiorespiratory fitness (CRF) and body fat percentage for overweight or obese persons. Methods: A systematic search of randomized controlled trials using the health science databases occurred up to April, 2020. Twenty-six studies were included for complete analysis. A total of 784 participations were analyzed. The unstandardized mean difference for each outcome measurement was extracted from the studies and pooled with the random effects model. Results: MICT was significantly better at improving CRF compared with SIT (mean difference = −0.92; 95% confidence interval, −1.63 to −0.21; P = .01; I2 = 10%). Furthermore, there was no significant difference between MICT versus HIIT on CRF (mean difference = −0.52; 95% confidence interval, −1.18 to 0.13; P = .12; I2 = 23%). There was no significant difference in body fat percentage between MICT versus HIIT and MICT versus SIT. Conclusions: MICT was significantly better at improving CRF than SIT in overweight or obese persons.

The menopausal transition is associated with increased prevalence of hypertension, and in time, postmenopausal women (PMW) will exhibit a cardiovascular disease risk score similar to male counterparts. Hypertension is associated with vascular dysfunction, but whether hypertensive (HYP) PMW have blunted nitric oxide (NO)-mediated leg vasodilator responsiveness and whether this is reversible by high-intensity training (HIT) is unknown. To address these questions, we examined the leg vascular conductance (LVC) in response to femoral infusion of acetylcholine (ACh) and sodium nitroprusside (SNP) and skeletal muscle markers of oxidative stress and NO bioavailability before and after HIT in PMW [12.9 ± 6.0 (means ± SD) years since last menstrual cycle]. We hypothesized that ACh- and SNP-induced LVC responsiveness was reduced in hypertensive compared with normotensive (NORM) PMW and that 10 wk of HIT would reverse the blunted LVC response and decrease blood pressure (BP). Nine hypertensive (HYP (clinical systolic/diastolic BP, 149 ± 11/91 ± 83 mmHg) and eight normotensive (NORM (122 ± 13/75 ± 8 mmHg) PMW completed 10 wk of biweekly small-sided floorball training (4–5 × 3–5 min interspersed by 1–3-min rest periods). Before training, the SNP-induced change in LVC was lower ( P < 0.05) in HYP compared with in NORM. With training, the ACh- and SNP-induced change in LVC at maximal infusion rates, i.e., 100 and 6 µg·min−1·kg leg mass−1, respectively, improved ( P < 0.05) in HYP only. Furthermore, training decreased ( P < 0.05) clinical systolic/diastolic BP (−15 ± 11/−9 ± 7 mmHg) in HYP and systolic BP (−10 ± 9 mmHg) in NORM. Thus, the SNP-mediated LVC responsiveness was blunted in HYP PMW and reversed by a period of HIT that was associated with a marked decrease in clinical BP.

Objective: In this study, we aimed to investigate oxidative stress and antioxidant parameter levels in patients with carbon monoxide (CO) poisoning. Methods: The study was conducted prospectively between March 1, 2015 and April 30, 2016 in the pediatric emergency department. Eligible patients included children aged 0–18 years old with a diagnosis of CO poisoning. To determination of oxidative stress and antioxidant parameter levels, venous blood with heparinized and urine samples were drawn during the admission and after normobaric oxygen (NBO) and hyperbaric oxygen (HBO) treatment. Results: Forty-seven children with CO poisoning for study group and 29 patients as control group were included to the study. Sixteen patients treated with HBO. Basal plasma malondialdehyde levels were found to be significantly higher in the CO poisoning group when compared with the control group ( p = 0.019). There is no significant difference in oxidative stress and antioxidant parameter levels except erythrocyte catalase enzyme levels in patients treated with NBO when comparing before and after NBO treatment ( p > 0.05). Decreasing of basal erythrocyte catalase enzyme levels were found statistically significant after NBO treatment ( p = 0.04). There was no significant difference in oxidative stress and antioxidant parameter levels in patients treated with HBO before and after therapy ( p > 0.05). Conclusions: CO poisoning is associated with increased lipid peroxidation in children immediately after the poisoning. However, both treatment modalities including NBO or HBO do not have a significant effect on oxidative stress or antioxidant parameter levels.

Time-effective protocols may potentially increase people’s compliance with exercise. The purpose of this paper was to compare the relative effects of 16 weeks of high intensity (resistance) training (HIT) with and without protein supplementation (HIT&P) and HVHIT (high volume/high intensity training) versus a nontraining control group on cardiometabolic risk factors. One hundred and twenty untrained males 30–50 years old were randomly assigned to 3 subgroups: (a) a HIT group; (b) a HIT&P group, and (c) a waiting-control group (phase I) that crossed over to (d) high volume/high intensity training (HVHIT) during the second study phase. HIT was defined as “single set to failure protocol” while HVHIT consistently applied two sets. Protein supplementation provided an overall intake of 1.5 g/kg/body mass. Primary study endpoint was the metabolic syndromeZ-Score (MetS-Z-Score). MetS-Z-Score significantly improved in all exercise groups (p≤0.001) with no significant difference between HIT, HIT&P, and HVHIT (p≥0.829). However, all the exercise groups differed significantly from the CG (p<0.001) which deteriorated significantly (p=0.039). In conclusion, all exercise protocols were similarly effective in improving cardiometabolic risk factors. Thus, HIT may be the best choice for people with low time budgets looking to improve their cardiometabolic health.

The aim of the present study was to investigate the concentration of ubiquinone-10 (Q10), at rest, in human skeletal muscle and blood plasma before and after a period of high-intensity training with or without Q10 supplementation. Another aim was to explore whether adenine nucleotide catabolism, lipid peroxidation, and mitochondrial function were affected by Q10 treatment. Seventeen young healthy men were assigned to either a control (placebo) or a Q10-supplementation (120 mg/day) group. Q10 supplementation resulted in a significantly higher plasma Q10/lotal cholesterol level on Days 11 and20compared with Day 1. There was no significant change in the concentration of Q10 in skeletal muscle or in isolated skeletal muscle mitochondria in either group. Plasma hypoxanthine and uric acid concentrations increased markedly after each exercise test session in both groups. After the training period, the postexercise increase in plasma hypoxanthine was markedly reduced in both groups, but the response was partially reversed after the recovery period. It was concluded that Q10 supplementation increases the concentration of Q1O in plasma but not in skeletal muscle.

The present study examined the effect of intensive training in combination with marked reduction in training volume on phospholemman (FXYD1) expression and phosphorylation at rest and during exercise. Eight well-trained cyclists replaced their regular training with speed-endurance training (10–12 × ∼30-s sprints) two or three times per week and aerobic high-intensity training (4–5 × 3–4 min at 90–95% of peak aerobic power output) 1–2 times per week for 7 wk and reduced the training volume by 70%. Muscle biopsies were obtained before and during a repeated high-intensity exercise protocol, and protein expression and phosphorylation were determined by Western blot analysis. Expression of FXYD1 (30%), actin (40%), mammalian target of rapamycin (mTOR) (12%), phospholamban (PLN) (16%), and Ca2+/calmodulin-dependent protein kinase II (CaMKII) γ/δ (25%) was higher ( P < 0.05) than before the training intervention. In addition, after the intervention, nonspecific FXYD1 phosphorylation was higher ( P < 0.05) at rest and during exercise, mainly achieved by an increased FXYD1 Ser-68 phosphorylation, compared with before the intervention. CaMKII, Thr-287, and eukaryotic elongation factor 2 Thr-56 phosphorylation at rest and during exercise, overall PKCα/β, Thr-638/641, and mTOR Ser-2448 phosphorylation during repeated intense exercise as well as resting PLN Thr-17 phosphorylation were also higher ( P < 0.05) compared with before the intervention period. Thus, a period of high-intensity training with reduced training volume increases expression and phosphorylation levels of FXYD1, which may affect Na+/K+ pump activity and muscle K+ homeostasis during intense exercise. Furthermore, higher expression of CaMKII and PLN, as well as increased phosphorylation of CaMKII Thr-287 may have improved intracellular Ca2+ handling.
