Effect of Pyramidal Aerobic Training on Ventilatory Function in Cigarette Smokers

August 13, 2026 updated by: Tarek Taha Fathy, Cairo University

Statement of the problem:

Does the pyramidal aerobic training affect ventilatory function parameters in smokers?

Null hypothesis:

Pyramidal aerobic training has no significant effect on ventilatory function parameters (such as Forced Vital Capacity [FVC], Forced Expiratory Volume in one second [FEV₁], and Peak Expiratory Flow Rate [PEFR]) in adult smokers.

Study Overview

Detailed Description

This randomized controlled trial evaluates the effect of an eight-week pyramidal aerobic training program on ventilatory function in cigarette smokers. Forty male cigarette smokers aged 18 to 28 years will be randomly allocated to either a pyramidal aerobic training group or a control group. The intervention group will perform treadmill-based pyramidal aerobic training three times per week for eight consecutive weeks. Each session will include a warm-up, pyramidal aerobic training with ascending and descending intensity levels, and a cool-down. Training intensity will range from 20% to 80% of the participant's target heart rate calculated using the Karvonen formula. Ventilatory function will be assessed by spirometry, while functional capacity, health-related quality of life, and smoking abstinence self-efficacy will also be assessed at baseline and after the intervention.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Pyramidal Aerobic Training Group
Participants will receive pyramidal aerobic training on a treadmill three times per week for eight consecutive weeks.
Pyramidal aerobic training performed on a motorized treadmill three times per week for eight consecutive weeks. Each session consists of 5 minutes of warm-up, 20 minutes of pyramidal aerobic training with 5 ascending and 5 descending intensity levels, each lasting 2 minutes, followed by 5 minutes of cool-down. Training intensity ranges from 20% to 80% of the participant's target heart rate calculated using the Karvonen formula, with heart rate monitored using a pulse oximeter.
No Intervention: Control Group
Participants will be assigned to the control group.

Smoking Abstinence Self-Efficacy Questionnaire (SASEQ) Score
Time Frame: Baseline and after 8 weeks of intervention
Smoking abstinence self-efficacy will be assessed using the Smoking Abstinence Self-Efficacy Questionnaire (SASEQ). The questionnaire score ranges from 9 to 16, with higher scores indicating greater smoking abstinence self-efficacy.
Baseline and after 8 weeks of intervention
