OBJECTIVE: To evaluate the impact of inspiratory muscle training on aerobic
capacity and pulmonary function in patients with ankylosing spondylitis. DESIGN:
Randomized controlled study. SETTING: Rheumatic Rehabilitation Centre. SUBJECTS:
A total of 54 ankylosing spondylitis patients, all males, were randomized to a
conventional exercise training associated with an inspiratory muscle training
group, or to a conventional exercise training group. INTERVENTIONS: Group 1 (27
patients) performed eight weeks of conventional exercise training (supervised
weekly group sessions followed by a home-based exercise programme) associated
with inspiratory muscle training sessions. Group 2 (27 patients) received eight
weeks of conventional exercise training only. MAIN MEASURES: Resting pulmonary
function (forced vital capacity - FVC, forced expiratory volume in one second -
FEV1); effort ventilatory efficiency (lowest ventilatory equivalent ratio for
oxygen and carbon dioxide - VE/VO2 and VE/VCO2) and aerobic capacity (peak oxygen
uptake - VO2peak) were assessed at baseline and after eight weeks of
exercise-based intervention. RESULTS: After eight weeks follow-up, patients in
Group 1 had a significant increased chest expansion and VO2peak compared with
Group 2 (3.6 +/-0.8 cm vs. 3.2 +/-0.5 cm, P = 0.032; 2.0 +/-0.5 l/min vs. 1.8
+/-0.3 l/min, P = 0.033). There were no significant differences of spirometric
measurements, except FVC which significantly improved in patients who performed
inspiratory muscle training (82.7 +/-5.1% vs. 79.5 +/-3.5%, P = 0.014). VE/VCO2
also improved significantly in Group 1 (26.6 +/-3.6 vs. 29.2 +/-4.7, P = 0.040).
CONCLUSIONS: Ankylosing spondylitis patients who performed eight weeks of
inspiratory muscle training associated to conventional exercise training had an
increased chest expansion, a better aerobic capacity, resting pulmonary function
and ventilatory efficiency than those who performed conventional exercise
training only.
