Description
Introduction: For training therapy in cancer patients, accurately defining exercise intensities and durations capable of inducing substantial immunological responses is essential (1). Moreover, dose–response relationships in patients remain difficult to establish because exercise modalities are often insufficiently prescribed or reported in existing studies (2). To address these gaps, this study examined how different continuous and interval-based cycling exercises across individualized intensity zones and different durations influences acute changes in immune-relevant markers in healthy adults.
Methods: Healthy, physically active participants (n=29) performed an incremental exercise test to determine lactate thresholds (LT1/LT2) and ventilatory thresholds (VT1/VT2). Based on these thresholds, low-, moderate- and high-intensity bouts were prescribed either as continuous exercise (CON; n=15) or interval exercise (INT; n= 14). Participants completed multiple exercise formats of varying durations and intensities. During all training sessions, lactate, glucose, and heart rate were continuously monitored and venous blood samples were collected pre-exercise, immediately post-exercise, and one hour into recovery.
Results: Recruitment and data acquisition are ongoing. The final analyses will characterize intensity–duration relationships and their impact on acute immunological responses across all exercise modalities. Results will be presented at the conference.
