简要总结
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.

研究组 & 干预措施
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
干预措施: Intervention group - telephone and print exercise intervention (Behavioral)
Control group
The control group (CG) were encouraged to continue previous lifestyle.
结局指标
主要结局
Change from Baseline Cardiorespiratory fitness at 6 months
时间窗: 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.
Cardiorespiratory fitness was measured by a modified Balke protocol on a treadmill and registered in ml/kg/min
Change from Baseline Waist circumference at 6 months
时间窗: 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.
Waist circumference was registered using a measuring band and the mean of two measures was recorded to the nearest half-centimeter.
Change from Baseline Muscular endurance of the back extensors at 6 months
时间窗: 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.
The static back extension test recorded muscular endurance of the back extensors as number of seconds the subject managed to endure a static horizontal position, with their lower body supported by a bench (max 240 sec).
Change from Baseline Hand grip strength at 6 months
时间窗: 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.
Hand grip strength was registered to the nearest 1 kilogram (kg) using a hydraulic dynamometer
Change from Baseline Neuromotor fitness at 6 months
时间窗: 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.
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).
Change from Baseline Muscular dynamic endurance of and the ability to stabilize the upper body at 6 months
时间窗: 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.
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
时间窗: 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.
Flexibility of the hamstring musculature was recorded using the sit-and-reach test to the nearest half centimeter, using a specially designed box.
Change from Baseline Flexibility in the shoulder joint at 6 months
时间窗: 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.
Flexibility of the shoulder joint was registered to the nearest centimeter, using the back-scratch test. The mean registered flexibility score of both shoulders was recorded.
Change from Baseline Explosive power in the lower extremities at 6 months
时间窗: 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.
Explosive power in the lower extremities was recorded to the nearest centimeter, using the vertical jump test.
Change from Baseline Body mass index at 6 months
时间窗: 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.
Body mass index was calculated using the formula weight/height\^2. Height and weight were measured using a measuring band (meters) and a weight scale (kilograms) respectively.
Change from Baseline Fat percentage at 6 months
时间窗: 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.
Fat percentage was measured using the bioimpedance machine InBody 720 and using skinfolds. Both registered body fat percentage.
