Brief Summary

This study compared different frequency low-volume resistance training (RT) on total, android, gynoid and trunk body fat in obese older women

Conditions

Obesity

Outcome Measures

Primary Outcomes (2)

• Change in body composition

  Whole-body dual-energy X-ray absorptiometry (DXA) scans (Lunar Prodigy, model NRL 41990, GE Lunar, Madison, WI) were used to assess total body fat, trunk fat, gynoid fat and android fat. Prior to scanning, participants were instructed to remove all objects containing metal. Scans were performed with the subjects lying in the supine position along the table's longitudinal centerline axis. Feet were taped together at the toes to immobilize the legs while the hands were maintained in a pronated position within the scanning region. Both calibration and analysis were carried out by a skilled laboratory technician. Equipment calibration followed the manufacturer's recommendations. The software generated standard lines that set apart the limbs from the trunk and head. These lines were adjusted by the same technician using specific anatomical points determined by the manufacturer. The results are presented in kilograms (kg)

  baseline and 12 weeks

• Change in fat z-score

  A composite z-score, was calculated using the following formula: (total body fat z-score) + (gynoid body fat z-score) + (android fat z-score) / 3. Z-scores were obtained from the DXA using standard software.

Study Arms (3)

Intervention 2X/week (G2X)

ACTIVE COMPARATOR

This group performed resistance training twice a week (Tuesdays and Thursdays)

Other: Intervention 2X/week (G2X)

Intervention 3X/week (G3X)

ACTIVE COMPARATOR

This group performed resistance training three sessions a week (Mondays, Wednesdays, and Fridays).

Other: Intervention 3X/week (G3X)

Control group (GC)

NO INTERVENTION

This group did not perform any type of organized physical exercise during the study period.

Interventions

Intervention 2X/week (G2X) OTHER

Participants performed resistance training (RT) composed of eight exercises performed for one set of 10-15 repetition maximum (RM). The rest interval between exercises was 2-3 min. Participants were instructed to control the speed of movement in the ratio of 1:2 for concentric and eccentric muscle actions, respectively. The progression of training loads in each exercise occurred, when a participant completed 15 repetitions in two consecutive sessions, with increases of 2-5% in exercises for the upper limbs, and 5-10% in exercises for the lower limbs. At the end of each session, one static stretching exercise at the point of discomfort for 15 seconds was performed for all major muscle groups for a total of exercises. Participants were asked not to perform any other type of organized physical exercise during the entire study period.

Intervention 2X/week (G2X)

Intervention 3X/week (G3X) OTHER
