Abstract:
Background: Phase angle (PA) is a strong predictor of sarcopenia,
muscular function, fragility and risk of mortality in older adults,
while strength and flexibility are required to perform different
daily activities.
Aim: This study aimed to compare the effects of different weekly
mixed training (aerobic and resistance) frequencies performed
over a 24-week exercise program on phase angle, flexibility and
handgrip strength (HS) in obese people.
Methods: Forty-two women (56.2 ± 9.1 years, BMI 37.1 ± 4.9 kg/
m2) were randomly allocated to one of two groups: a group with
a high-weekly training frequency of three times a week (HIGH, n=
21) and a group that performed only one weekly session (LOW,
n= 21). The groups trained with an identical exercise intensity and
volume per session for 6 months. In addition, the participants
followed a restricted caloric diet throughout the duration of the
study. Before and after the intervention period, the participants
were assessed for anthropometric measures, bioimpedance
analysis, and physical performance tests of flexibility (sit and
reach) and handgrip strength (HS).
Results: There was a significant group × time interaction (P <
0.05) for waist circumference (WC), bioimpedance reactance
divided by body height (Xc/H), PA, flexibility and HS measures,
even after adjusting for weight loss, menopausal status and age.
In addition, only the HIGH group increased Xc/H, PA, flexibility
and HS after the intervention period (P < 0.05).
Conclusions: Physical exercise performed three times a week
promotes better adaptations in PA and physical performance when
compared with the same program performed once a week in obese
women.
