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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Intervention group - telephone and print exercise intervention | Experimental | 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 |
|
| Control group | No Intervention | The control group (CG) were encouraged to continue previous lifestyle. |

| Change from Baseline Neuromotor fitness at 6 months | Neuromotor fitness was registered using the one leg standing test where the duration each subject managed to hold a balancing position was recorded in seconds (max 60 seconds). | Data collected prior to (pre) and after (post) a 6 month intervention period. Pretest was conducted in March-April, 2011 and post test was conducted in October-November, 2011. |
| Change from Baseline Muscular dynamic endurance of and the ability to stabilize the upper body at 6 months | Muscular dynamic endurance of and the ability to stabilize the upper body was registered using a modified push-ups test. The amount of correctly performed repetitions completed in 40 seconds, was recorded in number. |

| Change from Baseline Flexibility of the hamstring musculature at 6 months | Flexibility of the hamstring musculature was recorded using the sit-and-reach test to the nearest half centimeter, using a specially designed box. | Data collected prior to (pre) and after (post) a 6 month intervention period. Pretest was conducted in March-April, 2011 and post test was conducted in October-November, 2011. |
| Change from Baseline Flexibility in the shoulder joint at 6 months | Flexibility of the shoulder joint was registered to the nearest centimeter, using the back-scratch test.
