Brief Summary

Pilates exercises have been shown to be effective for a range of outcomes; however, it is unclear whether they can effectively contribute to fat mass reduction, especially when compared with a technique known to be effective for this purpose, such as aerobic training. Furthermore, Pilates' potential for increasing lean mass also requires further investigation. The aim of this study was to assess the effectiveness of Pilates compared with aerobic training, as well as the combination of these activities, on body composition in young adults. Eighty women aged 18 to 40 years were randomized to four groups: Pilates (n = 20), aerobic (n = 20), Pilates plus aerobic (n = 20), and control (n = 20). Body composition was assessed by dual-energy X-ray absorptiometry (DXA), considering: total fat mass (kg), percentage of total fat mass (%), total lean mass (kg), and total lean mass adjusted for height (kg/m²). Additionally, total body mass (kg) and body mass index (BMI) (kg/m2) values were considered. The interventions were carried out for 12 weeks, three times a week, lasting 60 minutes/session. Analyses were performed by intention-to-treat and per protocol.

Study Groups

Pilates

A total of 13 exercises were selected for the Pilates group, including two stretching exercises and 11 strengthening exercises for the main muscle groups. Mat exercises and equipment exercises (Ladder Barrel, Cadillac, Step Chair, Reformer, Springboard, and Small Barrel) will be used. Two protocols will be adopted for progression (protocol 1: weeks 1-6; protocol 2: weeks 7-12). Two sets of 10 repetitions will be performed, with a 30-second rest between sets and exercises. The two-by-two rule will be used to increase the load. In this case, the load will increase when the participant performs ≥ 2 repetitions above their target of 10 repetitions in the last set, in two consecutive training sessions. The interventions will last 12 weeks, three times a week, for 60 minutes.

Group Type: EXPERIMENTAL

Pilates exercises

Intervention Type: OTHER

Pilates exercises are characterized as muscle strengthening and stretching.

Aerobic

The aerobic group will perform walking/running exercises on a treadmill using the extensive interval training method. To define the intensity and periodization of the training, the running speed associated with V̇O2max (vV̇O2max), second ventilatory threshold (vLV2), and average speed between vV̇O2max and vLV2 (v50%Δ) will be used as reference. These parameters will be obtained from a maximal exercise test on a treadmill, performed before the start of the interventions. Two protocols will be adopted, with adjustments in density (work-to-recovery ratio) every two weeks. The interventions will last 12 weeks, three times a week, for 60 minutes.

Group Type: EXPERIMENTAL

Aerobic exercise

Intervention Type: OTHER

Aerobic exercises are characterized as a modality that works cardiorespiratory fitness.

Pilates plus aerobic

They will perform the same exercises as the Pilates group, however, with 1 set of 10 repetitions, with a 30-second rest between sets and exercises, totaling 30 minutes of intervention per session. In the second half of the intervention period, aerobic exercises will be performed, identical to those of the aerobic group, but for 30 minutes. The interventions will last 12 weeks, three times a week, for 60 minutes.

Group Type: EXPERIMENTAL

Pilates exercises plus aerobic exercise

Intervention Type: OTHER

Pilates exercises are characterized as muscle strengthening and stretching, while aerobic exercises are characterized as a modality that works cardiorespiratory fitness.

Control

This group will be instructed to maintain their usual routine.

Group Type: NO_INTERVENTION

No interventions assigned to this group
