Aktiv i Sør: a Randomized Controlled Trial (AiS)

23 mai 2017 mis à jour par: Monica Klungland Torstveit, University of Agder

The Effect of a Tailored Telephone and Email Based Physical Activity Intervention on Physical Fitness and Body Composition: a Randomized Controlled Trial

The purpose of this regional parallel-group RCT was to assess the effect of a six-month tailored telephone and email based physical activity intervention on various measures of physical fitness and body composition in a sample of physically inactive adults. A total of 111 physically inactive adults (40-55yr) from Agder, Norway were randomly allocated to either an intervention group (IG;n=56) or a no-intervention control group (CG;n=55). The IG received tailored exercise recommendations, every two months by email or mail (print) in addition to motivational follow-ups every second week, alternatively by email and telephone. Primary outcome measures were various objective measures of musculoskeletal and cardiorespiratory fitness in addition to various measures of body composition, including waist circumference, body mass index and fat percentage, which were assessed pre- and post-intervention.

Intervention / Traitement
Expérimental: Intervention group - telephone and print exercise intervention
The intervention group (IG) received a total of three intervention packages, one every second month, during the intervention period. The first intervention package was distributed at intervention start. The intervention package consisted of a tailored exercise program, national recommendations for physical activity, prompts and reminders. Additionally the IG received fortnightly supportive motivational contact every two weeks, alternately by telephone og email
Intervention has previously been described.
Aucune intervention: Control group
The control group (CG) were encouraged to continue previous lifestyle.
