Clinical Trial Summary
Concurrent and aerobic physical exercise are recognized strategies for the treatment of
overweight and obesity. The interventions of these modalities have been performed with
cardiovascular machines or guided execution in their majority, making it possible to improve
the health of this population; however, the studies have used high-cost equipment that is not
very accessible to the general population. For this reason, we propose to compare the effects
of two 12-week programs: concurrent vs. aerobic, using an innovative methodology with
musicalized and outdoor activities, little approached by research. The polarized training
intensity distribution model, usually used in sports and now applied to physical activity to
improve VO2max, muscular strength, and body composition, will be used to determine which
intervention is superior in improving these variables.
Description:
Twenty-eight people (women and men) will be randomly assigned to a concurrent exercise group
(intervention group) and an aerobic exercise group (comparator group), with fourteen people
per group. These interventions will be performed for 12 weeks, 3 times per week, with a
duration of 60 minutes per session. The first 8 minutes will be of general and specific joint
mobility preparing the participants for the central part which will be 47 minutes, and will
end with 5 minutes of return to calm.
The concurrent exercise group sessions will have two components, lasting 47 minutes. One of
them will be strength exercises with a time of 23 minutes, to perform 7 exercises. In the
first four weeks, it will be a general circuit, composed of 2 sets, 15 to 18 repetitions, for
60 seconds, with micro-pauses of 10 seconds between exercises, and 3 minutes between sets. In
weeks 5 to 8, it will be a block circuit, consisting of 3 sets, 12 to 15 repetitions, for 45
seconds, with micro-pauses of 10 seconds between exercises and 70 seconds between sets. For
weeks 9 to 12, it will be a concentrated circuit, consisting of 3 sets, 8 to 12 repetitions,
for 35 seconds, with micro-pauses of 15 seconds between exercises and 110 seconds between
sets.
The aerobic component will have a duration equal to the strength component (24 minutes). A
variable continuous method will be applied for the first 18 minutes through rumba-aerobic
(ballroom and folkloric dance steps), at an intensity lower than the ventilatory threshold 1
(VT 1). For the remaining 6 minutes, an intervallic method will be used at an intensity > VT
2, with combat gestures (fists, knees, and plantar flexions). Progression of the loads during
the 12 weeks of intervention: Weeks 1 and 2: 5 loads of 30 seconds and 30 seconds of
recovery.
Weeks 3 and 4: 4 loads of 45 seconds and 45 seconds of recovery. Weeks 5 to 7: 5 loads of 50
seconds and 25 seconds of recovery. Week 8: 4 loads of 60 seconds and 30 seconds of recovery.
Weeks 9 to 11: 3 loads of 70 seconds and 35 seconds of recovery. Week 12: 4 loads of 80 and
40 seconds of recovery.
The aerobic group, will perform the same methods, rumba steps, combat gestures, intensities,
and time of the central part of the aerobic component of the concurrent exercise group, but
will be differentiated by performing in the continuous method for a duration of 36 minutes
and in the interval method will have the following progression:
Weeks 1 and 2: 2 blocks by 5 loads of 35 seconds and 35 seconds of recovery. Weeks 3 and 4: 2
blocks by 4 loads of 45 seconds and 45 seconds of recovery. Weeks 5 to 8: 2 blocks by 4 loads
of 60 seconds and 30 seconds of recovery. Weeks 9 to 11: 2 blocks by 3 loads of 75 seconds
and 37.5 seconds of recovery. Week 12: 2 blocks by 4 loads of 80 seconds and 40 seconds of
recovery.
All participants will have their maximal oxygen consumption, muscle strength, and body
composition evaluated before the beginning of week 1 and at the end of week 12.
