Trial Outcomes & Findings for Strength Training and Endurance Exercise for LIFE (NCT NCT02101060)

NCT ID: NCT02101060

Last Updated: 2021-05-11

Results Overview

VO2 peak will be used as the primary measure of aerobic capacity. Subjects will be asked to exercise to voluntary exhaustion during a treadmill test using a modified Bruce protocol. In this Outcome, a mean difference between baseline to 16 weeks is reported (value at 16 weeks minus value at baseline).

PRIMARY outcome

Timeframe: at baseline and at 16 weeks (before and after the intervention phase)

Population: We have incomplete data on completers in the control group.

VO2 peak will be used as the primary measure of aerobic capacity. Subjects will be asked to exercise to voluntary exhaustion during a treadmill test using a modified Bruce protocol. In this Outcome, a mean difference between baseline to 16 weeks is reported (value at 16 weeks minus value at baseline).

PRIMARY outcome

Timeframe: at baseline and at 16 weeks (before and after the intervention phase)

Population: We have incomplete data on completers in these groups.

Exercise stress two-dimensional transthoracic echocardiography with tissue Doppler imaging (stress-echo) will be used to collect data on diastolic function. Reporting on ejection fraction. In this Outcome, a mean difference between baseline to 16 weeks is reported (value at 16 weeks minus value at baseline).

SECONDARY outcome

Timeframe: at baseline and at 16 weeks (before and after the intervention phase)

Changes in plasma levels of biomarkers of chronic inflammation will be calculated pre/post intervention, and will be tested for association with changes in primary outcomes as well as between group differences. Presenting IL-18 values (log converted for analysis). In this Outcome, a mean difference between baseline to 16 weeks is reported (value at 16 weeks minus value at baseline).
