Monitoring Training Progress During Exercise Training in Cancer Survivors: A Sub maximal Exercise Test as an Alternative for a Maximal Exercise Test?

摘要

Objective: To examine the use of a submaximal exercise test in detecting change in fitness level after a physical training program, and to investigate the correlation of outcomes as measured submaximally or maximally.Design: A prospective study in which exercise testing was performed before and after training intervention.Setting: Academic and general hospital and rehabilitation center.Participants: Cancer survivors (N=147) (all cancer types, medical treatment completed >=3mo ago) attended a 12-week supervised exercise program.Interventions: A 12-week training program including aerobic training, strength training, and group sport.Main Outcome Measures: Outcome measures were changes in peak oxygen uptake (Vo_2peak) and peak power output (both determined during exhaustive exercise testing) and submaximal heart rate (determined during submaximal testing at a fixed workload).Results: The Vo_2peak and peak power output increased and the submaximal heart rate decreased significantly from baseline to postintervention (P<.001). Changes in submaximal heart rate were only weakly correlated with changes in Vo_2peak and peak power output.
