PurposeThe aim of this study was to evaluate the effects of low-volume high-intensity interval training and continuous low to moderate intensity training on quality of life, functional capacity and cardiovascular disease risk factors in cancer survivors.MethodsCancer survivors within 24 months post-diagnosis were randomly assigned into the low-volume high-intensity interval training group (n = 8) or the continuous low to moderate intensity training group (n = 8) group for 36 sessions (12 weeks) of supervised exercise. The low-volume high-intensity interval training (LVHIIT) group performed 7 × 30 s intervals (≥85% maximal heart rate) and the continuous low to moderate intensity training (CLMIT) group performed continuous aerobic training for 20 min (≤55% maximal heart rate) on a stationary bike or treadmill.ResultsSignificant improvements (time) were observed for 13 of the 23 dependent variables (ES 0.05–0.61,p ≤ 0.05). An interaction effect was observed for six minute walk test (18.53% [32.43–4.63] ES 0.50,p ≤ 0.01) with the LVHIIT group demonstrating greater improvements.ConclusionThese preliminary findings suggest that both interventions can induce improvements in quality of life, functional capacity and selected cardiovascular disease risk factors. The LVHIIT program was well tolerated by the participants and our results suggest that LVHIIT is the preferred modality to improve fitness (6MWT); it remains to be seen which intervention elicits the most clinically relevant outcomes for patients. A larger sample size with a control group is required to confirm the significance of these findings.

Objectives: To determine the effects of high intensity interval training (HIIT) or moderate intensity continuous exercise (MICE) in patients with myocardial infarction (MI). Background: Cardiovascular diseases are the leading cause of mortality and morbidity globally causing a significant reduction in the quality of life of these patients. Participation of these patients in rehabilitation programs which involve a significant component of exercise seems to help by improving functional capacity and quality of life (QoL). Despite the beneficial effect of exercise, the type of exercise that yields the best results is yet to be determined.Methods: Three databases (MEDLINE, CINHAL and SportDirect) were searched in May-June 2017 for original articles regarding the effect of two types of exercise in patients with myocardial infarction. Randomized control trial studies which enrolled patients with myocardial infarction and studied the effects of HIIT and/or MICE, were included in this review. Data were extracted and summarised and all studies were assessed for bias.Results: Both forms of exercise seem to improve the relevant outcome measures such as functional capacity, QoL, walking distance, fatigue and function of the left heart. However HIIT seemed to be better in comparison with MICE in improving these outcomes. Several limitations and risk of bias have been identified and reported.Conclusion: Both HIIT and MICE are recommended for patients with MI. Further research is required to conclusively support the superiority of HIIT over other types of exercise.

AbstractBackgroundUptake and completion rates for supervised exercise programmes (SEP) for patients with intermittent claudication (IC) are low. Current exercise prescription is a one size fits all approach, based on claudication pain thresholds, potentially limiting individual benefits. High-intensity interval training (HIIT) has the potential to overcome these barriers as it is a more time-efficient, objectively prescribed exercise programme. This study aimed to assess a novel HIIT programme for patients with IC in terms of safety, feasibility, tolerability and indicators of efficacy.Design/MethodsPatients referred to a usual-care SEP were invited to undertake an alternative HIIT programme. All recruited patients performed a baseline cardiopulmonary exercise test (CPET), to inform their exercise prescription. HIIT involved ten, one-minute high-intensity intervals on a stationary cycle ergometer interspersed with one-minute recovery intervals, performed three times per week for six-weeks. Outcomes included safety, feasibility, tolerability, walking distance and quality of life (QoL).Results144 patients with IC were referred, 95 met initial eligibility criteria (66%) and 30 (32%) were recruited for HIIT, of which 15 (50%) completed. Of the recruited patients, 90% were on optimal medical therapy and 40% had concomitant cardiac, cerebrovascular and/or respiratory disease.One serious adverse event was recorded and patients who completed the programme attended 100% of the sessions. Improvements in walking distances and quality of life were observed. Following recruitment of the first 20 patients, the inclusion criteria was refined on the basis of CPET, leading to improved completion rates.ConclusionThe study provides preliminary findings indicating that patients with IC can complete a short-term HIIT programme. HIIT also appears safe, well-tolerated and although not formally powered, walking distances and QoL appear to improve following HIIT. Further research to evaluate the role of HIIT in patients with IC seems warranted.

Intensity Training

Subjects performed high-intensity interval training (HIIT) and continuous moderate-intensity training (END) to evaluate 24-h oxygen consumption. Oxygen consumption during HIIT was lower versus END; however, total oxygen consumption over 24 h was similar. These data demonstrate that HIIT and END induce similar 24-h energy expenditure, which may explain the comparable changes in body composition reported despite lower total training volume and time commitment.

High Intensity Interval

Persons with permanent atrial fibrillation experience reduced exercise tolerance, weight gain, and an associated decline in overall health. We report on a 74-year-old man with permanent atrial fibrillation who underwent a 10-week high-intensity interval training program. Substantial improvements in heart rate, blood pressure, aerobic and functional capacity, and quality of life were observed. These are desirable as these patients are not candidates for other treatment options and more effective therapies for the treatment of atrial fibrillation are needed.
