BodyPump and Personal Training - Changes in Muscle Strength and Body Composition

Summary

This study is a four armed randomized controlled trial (RCT) where the main purpose is to investigate the effect on muscle strength and changes in body composition in overweight (BMI ˂ 25) "not regularly exercising" women aged 18-65, after 12 weeks of Body Pump (BP), compared with an inactive control group. The study will also measure energy expenditure during one session of BP. At the same time, the project will investigate the effect on muscle strength and changes in body composition in group training with, respective without, a personal trainer (PT).

H0: There's no different between the groups after 12 weeks of Body Pump and traditional strength training with and without a personal trainer on muscle strength and muscle mass in adult overweight females.

Conditions

• Overweight

Interventions

OTHER

BodyPump

Participants will be offered BP sessions at fitness centers in Oslo/Akershus. They will exercise three times a week. The instructors at all centers have a BP license from Les Mills, and the same program will be conducted at all centers at all times. The project manager has been in contact with Les Mills Scandinavia and has been given permission to use the training concept for research.

OTHER

Personal training

Participants in this group will be offered training with a PT at the Norwegian School of Sports Sciences. They will exercise with their PT three times per week. The training program for this group will be based on the exercises in the BP class, but repetitions will vary between 3-15, and series between 2-4.

OTHER

Resistance training with instructor

Participants in this group will be invited to train on their own, three times a week, at the Norwegian School of Sports Science. Prior to the intervention period they will receive a training manual, instructions of the exercises and advice about progression during the intervention period. They will also have a follow-up with the same instructor after six weeks. The training program for this group will be the same as for group B. The PT's from group B will also serve as training instructors.
