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.

Physically inactive adults are prevalent worldwide. This study compared the effects of short-term high-intensity interval training (HIIT) versus moderate-intensity continuous training (MICT) on heart rate variability (HRV) in physically inactive adults as a preliminary study. Thirteen physically inactive male adults (27.5 ± 3.80 years) were randomly assigned to HIIT (N = 7) or MICT (N = 6). The HIIT program consisted of 20 min of interval training with cycling to rest ratio of 10/50 s at ≥90% HRpeak, while the MICT program consisted of 40 min of continuous cycling at 60–75% HRpeak. Both groups completed eight sessions of training within two weeks. Time and frequency domains of HRV were measured for 20 min with Actiwave-Cardio monitor (CamNtech, UK). The number of R-R interval and inter-beat interval (IBI) were significantly improved (p < 0.05) in both HIIT and MICT programs following eight sessions of training. A significant interaction effect for group by time was found in the lnLF/HF ratio (p < 0.05) where it was only improved in the HIIT group from pre- to post-test. The HIIT program is superior to MICT in improving HRV in physically inactive adults. The HIIT program can be applied as a time-efficient program for improving cardiac-autoregulation.

High-intensity interval training (HIIT) is emerging as a safe and effective means to combat chronic diseases. The objective of this work was to perform a systematic review of the effect of HIIT interventions in an aging population. Three electronic databases were searched for randomized trials comparing the effect of HIIT and moderate-intensity continuous training in older adults. After a thorough screening process, 15 articles were identified as meeting the inclusion criteria. All studies expressed a comparable or superior effect of HIIT in cardiorespiratory fitness measures. No studies reported a lessened effect of HIIT in comparison with moderate-intensity continuous training. This systematic review demonstrates that HIIT is a useful exercise regimen, which can be used in older adults to increase cardiorespiratory fitness. More research is needed to determine the effects of HIIT in an aging, predominately female population.

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.
