Study finds exercise intensity not linked to mortality in older adults
Medical Express reports that a study published in The BMJ with 1567 participants prescribed high intensity interval training (HIIT) or moderate intensity continuous training (MICT) to older adults, with surprising results.
The researchers found no difference in all cause mortality between the control group (4.7%, 37 participants) and combined HIIT and MICT group (4.5%, 35 participants).
They also found no differences in cardiovascular disease or cancer between the control group and the combined HIIT and MICT group.
For example, the total proportion of participants with cardiovascular disease after five years was 15.6%, with 16% (125 participants) in the control group, 15% (58 participants) in the MICT group, and 15.3% (61 participants) in the HIIT group.
“This study suggests that combined MICT and HIIT has no effect on all cause mortality compared with recommended physical activity levels,” write the researchers.
