Conclusions HB exercise is slightly more effective than CB rehabilitation in terms of maintaining EC .
Background Exercise-based cardiovascular rehabilitation ( CR ) improves exercise capacity ( EC ) , lowers cardiovascular risk profile and increases physical functioning in the short term .
However , uptake of and adherence to a physically active lifestyle in the long run remain problematic .
Home-based ( HB ) exercise programmes have been introduced in an attempt to enhance long-term adherence to recommended levels of physical activity ( PA ) .
The current systematic review and meta- analysis aim ed to compare the longer-term effects of HB exercise programmes with usual care ( UC ) or centre-based ( CB ) CR in patients referred for CR .
Are aerobic interval training and continuous training isocaloric in coronary artery disease patients?
Background Aerobic interval training ( IT ) seems to be superior to continuous training ( CT ) in improving exercise capacity ( peak oxygen uptake ( VO2 ) ) in coronary artery disease ( CAD ) patients in some , but not in all studies . Based on theoretical calculations , these comparative studies stated that the energy expenditure ( EE ) of both programmes is similar . To date , the caloricity of both programmes has never been objective ly measured . Therefore , our aim was to objective ly measure the EE of the IT and CT programmes described in the protocol of the SAINTEX-CAD study ( based on Wisloff et al. ; ITw and CTw ) , and the actually performed training intensities in the SAINTEX-CAD study by Conraads et al. ( ITc and CTc ) . Methods Following a two-week run-in period with three IT and three CT training sessions , 18 male CAD patients ( mean age 62.4 ± 6.1 years ) performed four training sessions in r and om order on the cycle ergometer : an ITw , CTw , ITc and CTc test session . The EE was assessed by indirect calorimetry using gas exchange measurements obtained with the Oxycon mobile . Results We found a higher EE for CTc compared to ITc ( 352 ± 90.8 kcal versus 269 ± 70.7 kcal ; p = 0.026 ) , while CTw and ITw seemed to be isocaloric ( 317 ± 85.2 kcal versus 273 ± 65.3 kcal ; p = 0.42 ) . Higher lactate levels were reached after IT sessions ( ITw 5.42 ± 1.42 mmol/l , ITc 5.05 ± 1.38 mmol/l ) compared to CT sessions ( CTw 2.45 ± 1.04 mmol/l , CTc 3.41 ± 1.44 mmol/l ) ( p < 0.01 ) . Lactate levels increased above baseline levels ( 1.91 ± 0.34 mmol/l ) except for the CTw session . Conclusion CTc expended significantly more energy compared to ITc , showing that the programmes used in the SAINTEX-CAD study were not isocaloric . In contrast , isocaloricity was met for CTw and ITw
