Background: Increased plasma levels of inflammatory markers and markers of endothelial cell activation have been associated with increased risk for cardiovascular events. Exercise training may lower the risk for coronary heart disease by attenuating inflammation and improving endothelial function. The objective of this study was to evaluate effects of regular high-intensity exercise training on a wide range of markers of inflammation and endothelial cell activation. Materials and methods: Consecutively, 40 patients were prospectively randomized to a 6 months supervised high-intensity interval training programme or to a control group following successful percutaneous coronary intervention (PCI). Blood samples of 36 patients with stable angina, drawn at baseline (before PCI) and at 6 months, were analysed. Late luminal loss was measured at 6 months using quantitative coronary angiography. Results: At 6 months, levels of the inflammatory markers interleukin (IL)-6 and IL-8 were reduced and levels of the anti-inflammatory cytokine IL-10 increased in the training group only. The decrease in IL-6 and C-reactive protein levels were significantly correlated with the decrease in luminal loss following PCI. In contrast to these anti-inflammatory effects, training had no effect on markers of platelet-mediated inflammation, and the effect of training on markers on endothelial cell activation were rather complex showing attenuating (von Willebrand factor) and enhancing (E-selectin and vascular cell adhesion molecule 1) effects. Conclusions: Regular exercise training in stable angina patients following PCI may attenuate some, but not all, inflammatory pathways, potentially contributing to the beneficial effects of exercise training on restenosis.

This study sought to determine if personalized moderate-intensity continuous exercise training (MICT) combined with high-intensity interval training (HIIT) was more effective at improving comprehensive training responsiveness than MICT alone. Apparently healthy, but physically inactive men and women (n = 54) were randomized to a non-exercise control group or one of two 13-week exercise training groups: (1) a personalized MICT + HIIT aerobic and resistance training program based on the American Council on Exercise guidelines, or (2) a standardized MICT aerobic and resistance training program designed according to current American College of Sports Medicine guidelines. Mean changes in maximal oxygen uptake (VO2max) and Metabolic (MetS) z-score in the personalized MICT + HIIT group were more favorable (p < 0.05) when compared to both the standardized MICT and control groups. Additionally, on the individual level, there were positive improvements in VO2max (Δ > 4.9%) and MetS z-score (Δ ≤ −0.48) in 100% (16/16) of participants in the personalized MICT + HIIT group. In the present study, a personalized exercise prescription combining MICT + HIIT in conjunction with resistance training elicited greater improvements in VO2max, MetS z-score reductions, and diminished inter-individual variation in VO2max and cardiometabolic training responses when compared to standardized MICT.

AbstractExercise training is an effective method of weight management, and knowing about its influence on the hormones involved in the regulation of food intake and inflammation could be useful for body weight management. Therefore, the purpose of this study was to compare the effects of 6 weeks of high-intensity interval training (HIIT) and moderate-intensity continuous exercise training (MCT) on nesfatin-1, interleukin (IL)-6, and tumor necrosis factor alpha (TNF-α).Thirty sedentary overweight men (Mean±SD; age, 25±1 years) were divided into three (n=10) body mass index-matched groups. The participants in the training groups performed either HIIT or MCT protocols 3 days per week for 6 weeks followed by a week of detraining.Plasma IL-6 and TNF-α did not significantly change after training, but nesfatin increased significantly only with HIIT compared with the control group (p<0.05). In addition, fasting glucose, insulin, and homeostasis model estimated insulin resistance (HOMA-IR), decreased significantly following both HIIT and MCT training (p<0.05). After a detraining period, the plasma nesfatin-1 did not return to pre-training levels in the HIIT group.Both the HIIT and MCT groups had similar effects on inflammatory markers and insulin resistance in men who are overweight, but the HIIT seems to have better anorectic effects (as indicated by nesfatin) compared with MCT.

Heart failure is one of the most common cardiovascular diseases and is a final pathway of various cardiac pathologies. Exercise intolerance and dyspnea accompanied by dete­riorating quality of life are common issues in those suffering from heart failure and may persist despite optimal medical therapy. Exercise training in heart failure theoretically helps to slow down the deterioration of the heart by antagonizing excess neurohormonal activity in heart failure, which translated into better functional capacity and quality of life. Exercise prescription is a mean of assessing and interpreting clinical information and applying the principles of training to develop an appropriate regimen and should be tailored to patient’s clinical condition. Resistance training improves peak VO2, exercise capacity and quality of life in heart failure patients. Both continuous and interval exercise training are linked to better quality of life despite ambiguous results in mortality. The aim of this article is to discuss the benefits of exercise in patients with congestive heart failure, exercise prescription, and exercise program including high-intensity interval training, continuous training and resistance exercise.   Abstrak Gagal jantung adalah salah satu penyakit kardiovaskular yang paling sering ditemui dan merupakan akhir daripada banyak jenis patologi jantung. Intoleransi olahraga dan sesak nafas disertai dengan memburuknya kualitas hidup merupakan beberapa masalah yang sering dihadapi oleh pasien gagal jantung, meskipun telah diberikan pengobatan yang optimal. Latihan olahraga pada gagal jantung secara teoritis dapat memperlambat menurunnya fungsi jantung dengan melawan aktivitas neurohormonal yang meningkat pada kondisi gagal jantung yang dicerminkan dengan kapasitas fungsional dan kualitas hidup yang lebih baik. Preskripsi olahraga meliputi pemeriksaan dan interpretasi dari informasi klinis dan aplikasi dari prinsip latihan untuk membentuk regimen yang sesuai dan harus di sesuaikan dengan keadaan klinis pasien. Latihan beban memperbaiki fungsi VO2 puncak, kapasitas olahraga dan kualitas hidup pada pasien dengan gagal jantung. Kedua metode olahraga baik secara kontinu ataupun interval dihubungkan dengan kualitas hidup yang lebih baik meskipun masih ambigu dalam hal mortalitas. Tujuan artikel ini adalah membahas manfaat latihan fisik pada pasien dengan gagal jantung kongestif, cara peresepan serta membahas program high intensity interval training, continuous training serta latihan beban.

Abstract Background Interstitial lung disease is a debilitating condition associated with significant dyspnoea, fatigue, and poor exercise tolerance. Pulmonary rehabilitation is an effective and key intervention in people with interstitial lung disease. However, despite the best efforts of patients and clinicians, many of those who participate are not achieving clinically meaningful benefits. This assessor-blinded, multi-centre, randomised controlled trial aims to compare the clinical benefits of high intensity interval exercise training versus the standard pulmonary rehabilitation method of continuous training at moderate intensity in people with fibrotic interstitial lung disease. Methods Eligible participants will be randomised to either a standard pulmonary rehabilitation group using moderate intensity continuous exercise training or high intensity interval exercise training. Participants in both groups will undertake an 8-week pulmonary rehabilitation program of twice-weekly supervised exercise training including aerobic (cycling) and strengthening exercises. In addition, participants in both groups will be prescribed a home exercise program. Outcomes will be assessed at baseline, upon completion of the intervention and at six months following the intervention by a blinded assessor. The primary outcome is endurance time on a constant work rate test. Secondary outcomes are functional capacity (6-min walk distance), health-related quality of life (Chronic Respiratory Disease Questionnaire (CRQ), St George’s Respiratory Questionnaire idiopathic pulmonary fibrosis specific version (SGRQ-I), breathlessness (Dyspnoea 12, Modified Medical Research Council Dyspnoea Scale), fatigue (fatigue severity scale), anxiety (Hospital Anxiety and Depression Scale), physical activity level (GeneActiv), skeletal muscle changes (ultrasonography) and completion and adherence to pulmonary rehabilitation. Discussion The standard exercise training strategies used in pulmonary rehabilitation may not provide an optimal exercise training stimulus for people with interstitial lung disease. This study will determine whether high intensity interval training can produce equivalent or even superior changes in exercise performance and symptoms. If high intensity interval training proves effective, it will provide an exercise training strategy that can readily be implemented into clinical practice for people with interstitial lung disease.

Objective: Reactive oxygen species (ROS) have been proposed as signaling molecules mediating exercise training adaptation, but the ROS source has remained unclear. This study aimed to investigate the requirement for NADPH oxidase (NOX)2-dependent redox changes induced by acute and long-term high-intensity interval training (HIIT) in skeletal muscle in a mouse model lacking functional NOX2 complex due to deficient p47phox (Ncf1) subunit expression (ncf1* mutation). Methods: HIIT was investigated after an acute bout of exercise and after a chronic intervention (3x week for 6 weeks) in wildtype (WT) vs. NOX2 activity-deficient (ncf1*) mice. NOX2 activation during HIIT was measured using a genetically-encoded biosensor. Immunoblotting and single-fiber staining were performed to measure classical exercise-training responsive endpoints in skeletal muscle. Results: A single bout of HIIT increased NOX2 activity measured using electroporated p47roGFP oxidation immediately after exercise but not 1h after exercise. After a 6-week of HIIT regime, improvements in maximal running capacity and some muscle training-markers responded less to HIIT in the ncf1* mice compared to WT, including superoxide dismutase (SOD)2, catalase, hexokinase II (HK II), pyruvate dehydrogenase (PDH) and protein markers of mitochondrial oxidative phosphorylation complexes. Strikingly, HIIT-training increased mitochondrial network area and decreased fragmentation in WT mice only. Conclusion: This study provided evidence that HIIT exercise activates NOX2 complex in skeletal muscle and that the presence of functional NOX2 is required for specific skeletal muscle adaptations to HIIT relating to antioxidant defense, glucose metabolism, and mitochondria.

Background: Apoptosis is the physiological cell death that in natural conditions leads to the elimination of old, damaged, waste, and harmful cells. The aim of this study was the effect of eight weeks of high-intensity interval training (HIIT) with and without caloric restriction on gene expression of myocardial Bax and Bcl2 in mice. Methods: Present study was an experimental multi-group design with a control group conducted on 30 two-month old male mice. Subjects were divided into five homogenous groups including base control, control, caloric restriction, interval exercise training, and caloric restriction + interval exercise training. Training groups participated in interval exercise training five sessions per week for 8 weeks. The level of gene expression of myocardial Bax and Bcl2 was evaluated by real-time PCR. Data were analyzed using the one-way ANOVA at the level of (P<0.05). Results: The results showed that the training group had a significant increase in gene expression of myocardial Bcl2 in comparison with caloric restriction + exercise training (P<0.05) and a significant decrease in gene expression of myocardial Bax compared to the caloric restriction group (P<0.05). Also, exercise training and exercise training + caloric restriction significantly increased the gene expression of myocardial Bcl2 and significantly decreased Bax/Bcl2 ratio compared to caloric restriction, base control, and control (P< 0.05). Conclusion: It seems that high-intensity interval training without caloric restriction would provide a suitable environment for increasing the integrity of the mitochondrial membrane of myocardial cells and possibly apoptosis.

Data obtained in primarily Caucasian (C) and African American adults show that ethnicity does not mediate responsiveness to exercise training. It is unknown if Hispanics (H), who face elevated health risks and are less active than C, exhibit a similar response to exercise training. This study compared cardiorespiratory and hemodynamic responses to high intensity interval training (HIIT) between C and H women. Twelve C and ten H women ages 19–35 yr who were non-obese and inactive completed nine sessions of HIIT over a 3 wk period. Maximal oxygen uptake (VO2max) was assessed twice at baseline during which thoracic impedance was used to evaluate heart rate (HR), stroke volume (SV) and cardiac output (CO). Habitual physical activity was assessed using accelerometry. Results showed a significant main effect of training for VO2max in C and H (F = 13.97, p = 0.001) and no group by training interaction (p = 0.65). There was a main effect of training for CO and SV in C and H (F = 7.57, p = 0.01; F = 7.16, p = 0.02), yet post hoc analyses revealed significant increases were only exhibited in C. There was a tendency for a group by training interaction for a-VO2diff (F = 1.32, p = 0.054), and a large effect size was seen in H (d = 1.02). Overall, data show no effect of ethnicity on changes in VO2max with low-volume HIIT, yet C and H may achieve this outcome differently. Longer studies in similar populations are needed to verify this result.

Carnosine and anserine are dipeptides synthesized from histidine and β-alanine by carnosine synthase (ATPGD1). These dipeptides, present in high concentration in the skeletal muscle, form conjugates with lipid peroxidation products such as 4-hydroxy trans-2-nonenal (HNE). Although skeletal muscle levels of these dipeptides could be elevated by feeding β-alanine, it is unclear how these dipeptides and their conjugates are affected by exercise training with or without β-alanine supplementation. We recruited 20 physically active men, who were allocated to either β-alanine or placebo-feeding group matched for peak oxygen consumption, lactate threshold, and maximal power. Participants completed 2 wk of a conditioning phase followed by 1 wk of exercise training, a single session of high-intensity interval training (HIIT), followed by 6 wk of HIIT. Analysis of muscle biopsies showed that the levels of carnosine and ATPGD1 expression were increased after CPET and decreased following a single session and 6 wk of HIIT. Expression of ATPGD1 and levels of carnosine were increased upon β-alanine-feeding after CPET, whereas ATPGD1 expression decreased following a single session of HIIT. The expression of fiber type markers myosin heavy chain I and IIa remained unchanged after CPET. Levels of carnosine, anserine, carnosine-HNE, carnosine-propanal, and carnosine-propanol were further increased after 9 wk of β-alanine supplementation and exercise training but remained unchanged in the placebo-fed group. These results suggest that carnosine levels and ATPGD1 expression fluctuates with different phases of training. Enhancing carnosine levels by β-alanine feeding could facilitate the detoxification of lipid peroxidation products in the human skeletal muscle.NEW & NOTEWORTHY Carnosine synthase expression and carnosine levels are altered in the human skeletal muscle during different phases of training. During high-intensity interval training, β-alanine feeding promotes detoxification of lipid peroxidation products and increases anserine levels in the skeletal muscle.
