Abstract

Objectives: To analyze the effectiveness of a pedometer-based protocol to increase daily physical activity in healthy smokers, and to study the correlation between changes in physical activity and exercise capacity, degree of psychological tobacco-dependence and smoking habits. Methods: Twenty-three smokers with normal lung function were submitted to a one-month protocol aimed at increasing daily physical activity by using pedometers (DigiWalker SW-200 Yamax). Subjects were divided in two groups according to their baseline physical activity level: active (n=8; 6 male; 48±13 years; 44±31 pack/years), with subjects who achieved 10.000 steps/day; and inactive (n=15; 9 male; 51±10 years; 35±21 pack/years), with subjects who did not achieve 10.000 steps/day. Changes post-pre protocol in daily number of steps (Δ steps/day) were assessed, as well as the six minute walking distance (6MWT) and the degree of psychological tobacco-dependence (Fagestrom scale). Results: When comparing pre- and post-protocol, the active group did not show improvement in daily physical activity (13420±3010 versus 12240±4357 steps/day, respectively; p=0.13), whereas the inactive group did improve (7437±1678 versus 10290±1310 steps/day, respectively; p<0.0001). Δ steps/day was different between the groups (p=0.0001). The inactive group showed no correlation between Δ steps/day and 6MWT, Fagestrom scale or smoking habits, but only with the baseline level of daily physical activity (r=-0.60; p=0.02). Conclusions: These preliminary results indicate that inactive smokers are able to increase their daily physical activity by using pedometers, and the improvement is negatively related to the initial activity level.
