Once a week is not enough: The effect of different weekly training frequencies on phase angle and
physical performance in obese women
Francesco Campa

Stefania Toselli
University of Bologna, Italy
Background:
Phaseangle(PA)isastrongpredictorofsarcopenia,
muscular function, fragility and riskofmortality inolder adults,
while strength and flexibility are required to performdifferent
daily activities.
Aim:
This study aimed to compare theeffects of differentweekly
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-twowomen (56.2±9.1years, BMI 37.1±4.9kg/
m
2
)were randomlyallocated tooneof twogroups: agroupwith
ahigh-weeklytrainingfrequencyofthreetimesaweek(HIGH,n=
21) and a group that performedonly oneweekly session (LOW,
n=21).Thegroupstrainedwithanidenticalexerciseintensityand
volume per session for 6months. In addition, the participants
followeda restrictedcaloricdiet throughout thedurationof the
study. Beforeandafter the interventionperiod, theparticipants
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
promotesbetteradaptationsinPAandphysicalperformancewhen
comparedwiththesameprogramperformedonceaweekinobese

Speaker Biography
Francesco Campa is a PhD student at the University of Bologna in Italy. He works at the
Department of Biomedical Science and Neuromotor Sciences (DIBINEM). His research
interests include body composition, anthropometry and sports sciences. Furthermore,
he is interested in the effects of the hydration status on exercise performance. His most
recent publication is Bioimpedance Vector Analysis of Élite, Sub-Élite and Low-Level
Male Volleyball Players.
