“…16 The intensity of exercise in the able-bodied population is typically prescribed using percentages of maximum HR. Owing to alterations in the sympathetic control of the heart and a blunted heart rate response to exercise, these methods cannot be relied on following SCI.…”

Study Design: Randomized controlled trial. Objectives: To evaluate the effectiveness of the physical activity guidelines (PAG) for adults with spinal cord injury (SCI) to improve aspects of physical fitness. Setting: Community exercise facility. Methods: Twenty-three participants (age: 40.4 ± 11.6 years, C1-T11, 12.0 ± 10.0 years post injury) were randomized into PAG training (n = 12) or active control (CON, n = 11) groups. PAG training was 2x per week for 16 weeks and involved 20 min of aerobic exercise at a moderate to vigorous intensity and three sets of 10 repetitions (at 50-70% 1 repetition maximum; 1RM). Pre-and post-testing included peak exercise and aerobic endurance tests on an arm ergometer and 1RM testing. Results: Nineteen participants (PAG, n = 11; CON, n = 8) completed the 16-week training program and post-testing. There was a significant (Po0.05) increase in peak aerobic capacity (relative VO 2peak : 17.2%, absolute VO 2peak : 9.9%) and submaximal power output (26.3%) in the PAG group only. Increases in strength ranged from 11.5-38.9% and were significantly (Po0.05) different from CON for vertical bench press, seated row, and rickshaw press. Adherence to the exercise program was 85.2 ± 8.3% for PAG, 44.4 ± 34.3% for CON (Po0.01). Conclusion:The PAG for adults with SCI are sufficient to improve aspects of aerobic and muscular fitness and should be promoted as a means to improve physical capacity.

“…In fact, the efficacy of HIIT is suboptimal if the exercise intensity is inadequate, even among non-athletes. 8,9 Boyd et al 8 examined the impact of low-intensity (70% peak work rate) and high-intensity (100% peak work rate) interval training (8-10 repetitions of a "1-minute on, 1-minute off" protocol, 3 times a week for 3 weeks) in overweight and obese young adults. They showed that improvements in aerobic fitness and exercise performance are intensity dependent, though changes in markers of skeletal muscle oxidative capacity are not different between the groups.…”

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.

“…However, it is hard to determine the optimal exercise program in terms of intensity and volume [24]. There is an ongoing discussion if training in higher intensity zones substantially improves the patient's V O 2peak [25] and the exercise capacity for coronary artery disease (CAD) patients [26]. Some studies have indicated, in the case of vigorous physical activity, that the risk of sudden cardiac death [27] or myocardial infarction [28] increases.…”

Abstract-Exercise training (ET) is one of the decisive and crucial factors for reducing and preventing unexpected cardiac events. The aim of this work is to implement a proactive eHealth system that will allow patients, following a Cardiac Rehabilitation (CR) program outside the hospital, to exercise safely, according to their recommended training zones. The eHealth system includes a smartwatch application, a smartphone application and several server-side applications, working on predefined personalised scenarios, which are alerting, guiding and supporting the patients. The heart rate (HR) of patients is continuously measured, recorded and analysed during ET with the help of wearable devices. While training, patients benefit from multiple levels of feedback. Communities of patients are created for stimulating and motivating patients to perform according to their CR program. Opposed to traditional home-based CR eHealth applications, profiles and training zones are created and handled dynamically for each patient.
