Effect of Pyramidal Aerobic Training on Ventilatory Function in Cigarette Smokers
13. august 2026 opdateret af: 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.

Detaljeret beskrivelse
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.

Eksperimentel: 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.
