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.

High-intensity training is becoming more popular nowadays when people have less time to engage in prolonged physical activity. Expertly led high intensity training is a safe way to achieve desired fitness goals. The aim of the study was to check if there were significant changes in the concentrations of sodium, potassium, calcium, magnesium, zinc, iron and copper in the blood and urine of twelve trainees after a short but intense training. Blood and urine sampling was performed before and after high intensity training where bodyweight exercises and exercises with external load were used. Statistical analysis was performed using paired t-test (2-tailed) with α=0.05 as statistical significance. The results obtained showed that the measured mineral concentrations varied as a result of intense physical activity, but these variations were small and did not have a general trend of increase or decrease of analyzed mineral content. Based on these results, it can be concluded that, from the standpoint of the mineral concentrations loss, short high-intensity training is safe for the trainee’s health.

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.

Objective Long-term intensive training may led to ischemia oxygen reaction and increase the ROS. Astaxanthin, as the super antioxidant, was investigated to against anti-oxidative stress. By supplementing the astaxanthin, we wanted to observe if it can mediated Nrf2 reduces myocardial cell oxidative injury in rats after high intensity training of 6 weeks.  Methods 7-week SD male rats were divided into 3 groups randomly: control group ( C group,n =10),high intensity training group ( HT group,n = 15),astaxanthin and high intensity training group (HTA group,n = 15) . The rats in HTA group were given with astaxanthin 20 mg /kg·d and in HT group were given with oil during the training day.The serum cTnI,myocardial apoptosis index,  the expression of myocardial BAX, Bcl2, Nrf2, HO-1, myocardial MDA,SOD and T- AOC activity were measured 24 hours after the last training. Results After 6-week tranning of high intensity, compared with group C, the serum cTNI, myocardial apoptosis index, the expression of BAX and myocardial MDA were significantly higher in group HT(P<0.01).The Bcl2/Bax, the expression of HO-1, SOD and T-AOC activity were significantly declined (P<0.01). After the intervention of 6-week astaxanthin, compared with group HT, the serum cTNI, myocardial MDA, the myocardial apoptosis index, the expression of BAX were significantly lower in HTA group (cTNI(ng/ml): 1.16±0.27 VS 2.47±0.39, P<0.05; myocardial apoptosis index: 164.27±3.98 VS 196.20±9.65, P<0.01; BAX: 58.40±5.95 VS 78.03±3.80, P<0.01 ). Finally, Bcl2/Bax, SOD, T-AOC activity, the expression of Nrf2 and HO-1 were significantly higher  (Bcl2/Bax : 1.92±0.10 VS 1.19±0.18, P<0.01; SOD(U/mg): 52.38±6.15 VS 38.32±3.36, P<0.01; T-AOC(U/mg): 30.22±4.07 VS 23.76±3.20, P<0.01; Nrf2: 93.61±8.53 VS 74.26±6.69, P<0.01; HO-1: 84.99±13.78 VS 64.22±11.39, P<0.05).  Conclusions The supplement of astaxanthin can mediate Nrf2 signaling pathway, and elevate the expression of Nrf2 and HO-1. Then it can increase the activity of SOD and T-AOC and reduce the myocardial oxidative level and myocardial apoptosis in rats caused by 6-week high intensity training. Finally, the structure and function of heart tissue are back to normal.

Lifestyle, including regular physical activity and dietary habits, influences microbiota composition. Although some studies have demonstrated changes in microbiota composition due to moderate or high intensity training in athletes, the relationship between physical activity and changes in the intestinal bacteria is still a matter of discussion. In addition, as most studies are performed on males, the role of sexual dimorphism deserves to be explored. Therefore, the aim of this preliminary study was to ascertain the influence of an intensive training and the rat’s sex on caecal microbiota composition. For this purpose, female and male 4-week-old Wistar rats were submitted to a 4-week running training program. At the end, caecal samples were collected immediately after performing an exhaustion test to characterize the microbiota composition by 16S rRNA sequencing technique. Parallel groups of female and male sedentary (SED) rats (age matched) were included. The results showed that young female rats had a higher ability to run than males but no sex- or training-associated changes were observed on microbiota diversity and richness indexes among groups. However, the Actinobacteria, Bifidobacteriaceae and Bifidobacterium spp. proportions were significantly higher in male than in female rats when comparing SED groups (p < 0.05), whose proportions in males were decreased by the training program (p < 0.05 vs. SED). On the contrary, female SED rats showed a higher proportion of Odoribacteraceae (belonging to Bacteroidetes), Clostridiaceae and Eubacteriaceae (both Firmicutes) than in the respective male group (p < 0.05), although Eubacteriaceae proportion decreased by running (p < 0.05 vs. SED). However, training increased the proportion of the Paraeggerthella genus (Actinobacteria) in female rats with respect to its sedentary counterpart (p < 0.05). Overall, caecal microbiota composition is modified by intensive training in young rats but there are also sex-based differences that should be considered for interventional studies.
