“…Study characteristics are presented as mean ± SD unless otherwise stated. Eighteen effects from 17 RCTs [11,12,13,14,15,16,18,19,20,21,22,23,24,25,26,27,28] of 563 participants were included in the review (Table 1). Of the 17 included studies, 10 enrolled obese subjects [11,12,13,16,20,21,23,26,27,28], 1 included normal weight and obese subjects [39], and 6 included normal weight subjects [14,18,19,22,24,25].…”

“…In recent years, a number of experimental studies compared the effects of HIIT and MICT on CRF in children and adolescents, but the findings were inconsistent and inconclusive. Some intervention studies demonstrated that HIIT intervention stimulated significant increases in relative CRF when compared with MICT [11,12,13,14], while other studies did not observe any difference between these two methods [15,16,17,18,19,20,21,22,23,24,25,26,27,28]. Although there have been some systematic review suggested that the effect of HIIT on CRF is better than MICT [29,30], they focused on obese populations [30], or compared effect sizes with a non-exercise control group rather than a MICT group [31].…”

Enhancing cardiorespiratory fitness (CRF) can lead to substantial health benefits. Comparisons between high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on CRF for children and adolescents are inconsistent and inconclusive. The objective of this study was to perform a meta-analysis to compare the effects between HIIT and MICT on CRF in children and adolescents. We searched MEDLINE, PubMed, Web of Science, and Google Scholar to identify relevant articles. The standardized mean differences (SMD) and 95% confidence intervals (95% CI) were calculated to determine the pooled effect size of HIIT and MICT on CRF. A total of 563 subjects from 17 studies (18 effects) were identified. The pooled effect size was 0.51 (95% CI = 0.33–0.69) comparing HIIT to MICT. Moreover, intervention duration, exercise modality, work and rest ratio, and total bouts did not significantly modify the effect of HIIT on CRF. It is concluded that compared with endurance training, HIIT has greater improvements on cardiorespiratory fitness among children and adolescents.

“…Aerobic exercise training is able to ameliorate dyslipidemia, insulin resistance, endothelial function, and inflammatory status [ 230 ]. It is well known that exercise training exerts beneficial effects in healthy [ 231 ] and in individuals with SAH [ 232 ], T2D [ 233 ], obesity [ 234 , 235 ], cancer [ 236 ], coronary heart disease [ 237 ], and chronic heart failure [ 238 ].…”

MicroRNAs are small non-coding RNAs that regulate gene expression post-transcriptionally. They are involved in the regulation of physiological processes, such as adaptation to physical exercise, and also in disease settings, such as systemic arterial hypertension (SAH), type 2 diabetes mellitus (T2D), and obesity. In SAH, microRNAs play a significant role in the regulation of key signaling pathways that lead to the hyperactivation of the renin-angiotensin-aldosterone system, endothelial dysfunction, inflammation, proliferation, and phenotypic change in smooth muscle cells, and the hyperactivation of the sympathetic nervous system. MicroRNAs are also involved in the regulation of insulin signaling and blood glucose levels in T2D, and participate in lipid metabolism, adipogenesis, and adipocyte differentiation in obesity, with specific microRNA signatures involved in the pathogenesis of each disease. Many studies report the benefits promoted by exercise training in cardiovascular diseases by reducing blood pressure, glucose levels, and improving insulin signaling and lipid metabolism. The molecular mechanisms involved, however, remain poorly understood, especially regarding the participation of microRNAs in these processes. This review aimed to highlight microRNAs already known to be associated with SAH, T2D, and obesity, as well as their possible regulation by exercise training.

A cardiorespiratoricus fittség (aerob kapacitás, VO 2max ) mértéke nagymértékben meghatározza az életkilátásokat, ezért növelése az egészség helyreállítására a szervezett edzésprogramon alapuló multidiszciplináris rehabilitáció egyik fő célja -a többi rizikótényező csökkentése mellett. A (tünetek által behatárolt) egyenletes iramú testmozgások mellett egyre kiterjedtebb az interval jellegű "edzés". Ilyenkor a néhány perces intenzívebb szakaszt hasonló tartamú vagy hosszabb könnyű mozgás vagy passzív pihenő váltja (mérsékelt intenzitású interval edzés: MICE). Az intenzív szakasz történhet a tünetküszöb alatti maximális intenzitással is (high-intensity interval training: HIIT), sőt igen rövid, 10-30 másodperces szupramaximális és hosszabb pihenőszakaszok váltakozásával is (sprint interval training: SIT). Ezek előnye a 30-40%-kal rövidebb edzéstartam, emellett sokak számára ezek elfogadhatóbb edzésformák, változatosabbá teszik a programot, hatásosabban, extra veszély nélkül. Az interval jellegű rehabilitációs edzésprogramok helyet kapnak az egyéb kórállapotok kezelésében is, káros mellékhatások nélkül. Orv Hetil. 2018; 159(33): 1346-1352.Kulcsszavak: váltakozó intenzitású edzésterhelések a szívbetegeknek, mérsékelt intenzitású folyamatos edzés (MICE), nagy intenzitású interval edzés (HIIT), igen nagy (vágta-) intenzitású interval edzés (SIT), interval tréning egyéb kórállapotokban Cardiac rehabilitation and its sporty faceThe prognosis of cardiac and other diseases is highly determined by the level of cardiopulmonary fitness (aerobic capacity). The main purposes of rehabilitative activities include the restoration and increase of VO 2max . The "classic" method is the continuous aerobic exercise (moderate-intensity continuous exercise). The higher increase of aerobic capacity in a shorter time can be developed by interval loads: shorter or longer active periods are interspersed by lowintensity rest periods. A recent form is the high-intensity interval training: 0.5-4 minutes on 70-90% of the aerobic capacity followed by a rest or low-intensity biking/walking/jogging/any activity. The sprint interval training uses a few ten seconds of maximal intensity bursts changed with longer low-intensity activities. The advantages of the interval methods are shorter training time, less monotony, higher efficiency with not more risks. Interval training methods are applied also in other pathologies without disadvantages.Keywords: interval training methods in cardiac rehabilitation, moderate-intensity cardiac exercise, high-intensity interval training, sprint interval training, advantages of intensive exercise in non-cardiac pathologies Apor P.
