Acute Responses to Walking, Stair Climbing, and Functional Circuit Exercise

4 de setembro de 2026 atualizado por: Ramazan Bayer, Malatya Turgut Ozal University

Acute Metabolic, Respiratory, and Neuromotor Responses to Walking, Stair Climbing, and Functional Circuit Exercise in Sedentary Individuals: A Heart Rate-Controlled Randomized Crossover Study

This study evaluated the acute physiological responses to three different exercise modalities in sedentary young men. Participants completed walking, stair climbing, and functional circuit exercise sessions in a randomized crossover design. Each exercise session lasted 20 minutes and was performed at a target intensity of 50% heart rate reserve (±5 beats/min), with at least 72 hours between sessions.

The study compared acute respiratory, metabolic, and neuromotor responses to the three exercise modalities. Pulmonary function was assessed using spirometry, blood lactate concentration was measured using capillary blood samples, and countermovement jump performance was assessed as an indicator of neuromuscular performance. Heart rate was continuously monitored during each exercise session.
