“…Only 4HIIT increased VO 2 max after 6-week intervention, probably due to a longer tVO 2 max and improved estimated stroke volume. However, a shorter duration of the peak workload duration may lessen perceived exertion for individuals with a low aerobic fitness [14][15][16] and may easily be sustained and be performed with more repetitions, resulting in a similar tVO 2 max. 16 Matsuo et al 17,18 has proposed 3 × 3 min HIIT as a suitable protocol for Japanese as shown in his excellent review of HIIT studies among patients with obesity and metabolic syndrome.…”

Recently, high-intensity interval training (HIIT) has received much attention as a promising exercise option not only to improve aerobic fitness, but also to prevent and improve lifestyle-related diseases. Epidemiological studies have shown that the exercise volume, as determined by the product of exercise intensity, duration, and frequency, has been shown to be important for improvements in muscle mitochondrial activity and subsequent improvements in aerobic fitness, insulin sensitivity, and metabolic variables. Therefore, continuous moderate-intensity training has been widely recommended. On the other hand, the main contributor of HIIT to improvements in aerobic fitness and metabolic variables is its high-intensity nature, and many recent studies have shown results favoring HIIT when compared with conventional continuous training, despite its shorter exercise duration and smaller exercise volume. In this review, we aim to show the possible universal application of HIIT in a hospital setting, where athletes, sports lovers, and patients have sought medical advice and have the opportunity to undergo detailed evaluations, including an exercise stress test. For athletes, HIIT is mandatory to achieve further improvements in aerobic fitness. For patients, though higher levels of motivation and careful evaluation are required, the time constraints of HIIT are smaller and both aerobic and resistance training can be expected to yield favorable results because of the high-intensity nature of HIIT.

“…High Intensity Interval Training (HIIT) is more effective and more useful than intermediate intensity continuous training in increasing aerobic capacity and cardiovascular functions in healthy individuals and patients with cardiovascular diseases (11)(12)(13). Also, in comparison to traditional exercises with low to intermediate intensity, these types of training were more effective in cardiac revival, controlling blood sugar and most other clinical symptoms of diabetes, and the risk factors affecting cardiac patients in the long run (14,15).…”

A B S T R A C TBackground: To date, not sufficient information is available regarding the effect of High Intensity Interval Training (HIIT) on diabetes-induced myocardial dysfunctions. Objectives: The present study aimed to evaluate the effect of 4-week HIIT on change in expression levels of ryanodine receptor calcium channel (RyR2) and ATPase calcium pump (SERCA2a) in diabetic rats. Materials and Methods:This study was conducted on 24 Wistar rats with average weight of 245 ± 10 g. The rats were randomly divided into a sedentary diabetic group and a trained diabetic group. Training was started two weeks after diabetes induction by Streptozotocin (STZ) injection. The training program consisted of 4 weeks running on a treadmill and was considered to be intense for the two groups' diabetic rats. After all, the animals' characteristics and myocardial gene expression were compared using independent t-test. Results: Measurement of gene expression by Real Time-PCR revealed that cardiac mRNA expression of RyR2 was enhanced in the HIIT group. The results also revealed a significant (P = 0.03) difference between the hearts of the sedentary controls and the trained group regarding RyR2 levels. However, no significant difference was observed between the two groups with respect to SERCA2a levels (P = 0.14). Conclusions:The study results showed that treatment with HIIT could prevent and/or minimize the loss in expression of RyR2 and SERCA2a.

StreszczenieSpiroergometryczna próba wysiłkowa jest wykorzystywana do oceny wydolności fizycznej. W kardiologii znajduje zastosowanie w diagnostyce, planowaniu terapii, ocenie jej skuteczności i ocenie rokowania. Badanie to jest również wykorzystywane przez lekarzy innych specjalizacji, np. medycyny sportowej i medycyny pracy. Test spiroergometryczny polega na bezpośrednim pomiarze wymiany gazowej podczas próby wysiłkowej. W artykule przedstawiono najważniejsze parametry oceniane podczas testu oraz wskazania i przeciwwskazania do jego przeprowadzenia. Opisano też wyniki, najciekawszych według autorów, opublikowanych w ostatnim czasie badań klinicznych dotyczących wykorzystania testu spiroergometrycznego u pacjentów z chorobami układu krążenia i osób narażonych na niekorzystne dla zdrowia czynniki związane z pracą zawodową. W publikacjach tych oceniano zmienność parametrów oddechowych podczas testu spiroergometrycznego i po jego zakończeniu oraz ich wpływ na wartość prognostyczną badania. W niniejszej pracy przedstawiono ponadto doniesienia na temat optymalnego doboru obciąże-nia w treningu interwałowym w oparciu o zużycie tlenu na szczycie wysiłku. Med.

It is used in cardiology to define the diagnostic and prognostic information, the treatment and its effectiveness. This method is also useful in sport medicine and in occupational medicine. The cardiopulmonary exercise test involves measuring of gas exchange during exercise testing. The article presents the main parameters assessed during the test and the indications and contraindications for conducting the test. It also reveals the results of recently published clinical trials on the use of cardiopulmonary exercise test in patients with cardiovascular disease and in the working population. The study included variability of respiratory parameters during the cardiopulmonary exercise test and after its completion, as well as their impact on the prognostic value. In addition, the results of a study involving an optimal choice of interval training on the basis of oxygen consumption at peak exercise are summarized. Med Pr 2014;65 (5) WSTĘPSpiroergometryczna próba wysiłkowa (cardiopulmonary exercise test -CPET) jest najbardziej wiarygodną metodą wykorzystywaną do oceny wydolności fizycznej w celu uzyskania informacji prognostycznych niezbędnych w planowaniu leczenia i ocenie jego skuteczności. Dzięki tej szeroko stosowanej metodzie diagnostycznej uzyskuje się szczegółowe parametry pozwalające na dokładną ocenę kliniczną stanu pacjenta. Spiroergometryczna próba wysiłkowa, przeprowadzana na bieżni ruchomej lub cykloergometrze, jest połą-czeniem klasycznej próby wysiłkowej i pomiaru gazów w powietrzu oddechowym, co daje możliwość dokład-nej oceny odpowiedzi organizmu na wysiłek fizyczny oraz wydolności fizycznej badanego.Wydolność fizyczna to zdolność do wykonywania ciężkiej lub dłu...
