About this study
Official title: 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Walking ProtocolBehavioural
Also called WP
Participants performed a 20-minute walking exercise session at a target intensity of 50% heart rate reserve (HRR), maintained within ±5 beats/min of the individual target heart rate. Heart rate was continuously monitored throughout the exercise session.
Stair Climbing ProtocolBehavioural
Also called SP
Participants performed a 20-minute stair climbing exercise session at a target intensity of 50% heart rate reserve (HRR), maintained within ±5 beats/min of the individual target heart rate. Heart rate was continuously monitored throughout the exercise session.
Functional Circuit ProtocolBehavioural
Also called FCP
Participants performed a 20-minute functional circuit exercise session at a target intensity of 50% heart rate reserve (HRR), maintained within ±5 beats/min of the individual target heart rate. The circuit consisted of chair sit-to-stand, reverse lunges, wall push-ups, high-knee marching, and low-impact mountain climbers performed on an elevated surface. Heart rate was continuously monitored throughout the exercise session.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Forced Expiratory Volume in One Second (FEV1)
Forced expiratory volume in one second (FEV1) was measured by spirometry before and 5 minutes after each exercise condition. The primary outcome was the change in FEV1 (ΔFEV1), calculated as post-exercise FEV1 minus pre-exercise FEV1 and expressed in liters (L). Measurements were obtained following standardized spirometry procedures.
Measured: Baseline and 5 minutes after each exercise session
Secondary outcomes (8)
Change in Forced Vital Capacity (FVC)
Forced vital capacity (FVC) was measured by spirometry before and 5 minutes after each exercise condition. The outcome was the change in FVC (ΔFVC), calculated as post-exercise FVC minus pre-exercise FVC and expressed in liters (L).
Measured: Baseline and 5 minutes after each exercise session
Change in FEV1/FVC Ratio
The FEV1/FVC ratio was assessed by spirometry before and 5 minutes after each exercise condition. The outcome was the change in FEV1/FVC ratio (ΔFEV1/FVC), calculated as the post-exercise value minus the pre-exercise value.
Measured: Baseline and 5 minutes after each exercise session
Change in Peak Expiratory Flow (PEF)
Peak expiratory flow (PEF) was measured by spirometry before and 5 minutes after each exercise condition. The outcome was the change in PEF (ΔPEF), calculated as the post-exercise PEF minus the pre-exercise PEF and expressed in liters per second (L/s).
Measured: Baseline and 5 minutes after each exercise session
Change in Blood Lactate Concentration
Capillary blood lactate concentration was measured before exercise and 3 minutes after each exercise condition. The outcome was the change in blood lactate concentration (ΔLactate), calculated as the post-exercise value minus the pre-exercise value and expressed in millimoles per liter (mmol/L).
Measured: Baseline and 3 minutes after each exercise session
Change in Countermovement Jump Height (CMJ)
Countermovement jump (CMJ) height was assessed before and after each exercise condition. The outcome was the change in CMJ height (ΔCMJ), calculated as the post-exercise value minus the pre-exercise value and expressed in centimeters (cm).
Measured: Baseline and immediately after post-exercise spirometry initiated at 5 minutes after each exercise session
Mean Heart Rate During Exercise
Heart rate was continuously monitored throughout each exercise condition. Mean heart rate was calculated across the exercise period and expressed in beats per minute (bpm).
Measured: During each 20-minute exercise session
Maximum Heart Rate During Exercise
Heart rate was continuously monitored throughout each exercise condition. Maximum heart rate was defined as the highest heart rate recorded during the exercise period and expressed in beats per minute (bpm).
Measured: During each 20-minute exercise session
Time Spent in the Target Heart Rate Range
Heart rate was continuously monitored throughout each exercise condition. The outcome was the percentage of exercise time during which heart rate remained within ±5 beats/min of the individualized target heart rate corresponding to 50% heart rate reserve (HRR)
Measured: During each 20-minute exercise session
