Introduction: The purpose of the study was to determine how 8-week inter-
vention programme and a healthy lifestyle change affects overweight wom-
en, how it affects their motor capabilities (flexibility, strength endurance and
endurance), physical characteristics and psychological condition (self-imagine,
stress, satisfaction).
Methods: The sample consisted of 13 test subjects with excessive body weight
(average body weight was 110.2 kg), with IBM higher than 30 kg/m2, aged 31,85
± 4.3 years. The program lasted 8 weeks, included 16 exercise units and had
been held twice a week at the Faculty of Sport under the guidance of a gradu-
ate from the Faculty of Sport. The subjects had to individually perform aerobic
activity for at least 30 minutes, which means they were physical active at least
four times per week. They performed measurements of motor capabilities,
physical characteristics and psychological factors at the very beginning and the
very end of the program. The motor capability assessment consisted of 9 tests,
which were used to measure flexibility (2 tests: sit and reach test, shoulder flex-
ibility), strength endurance (6 tests: push-ups, pull-ups, sit-ups, the strength of
hip ad back extensors, squats, plank test) and endurance (1 test: YMCA 3-min
stepping test). We measured the body characteristics using a bioelectrical im-
pedance analysis. In addition to the abovementioned parameters we measured
abdominal, waistline and hip circumferences as well. The psychological factors
were measured by questionnaire which was related to a lifestyle, health, stress,
satisfaction and self-imagine. We compared the differences between the initial
and final states with the T-test for dependent samples, or in the case of a nor-
mal distribution violation, with a nonparametric test (Wilcoxon). All the analy-
ses were carried out at the characteristic level p ≤ 0.05.
Results: The differences between initial and final measurements of body char-
acteristics have been statistically significant; on average, the subjects’ body
weight decreased by 6.28, body fat by 2.55 %, BMI by 2.17 units, abdominal cir-
cumference by 6.3 cm, waistline circumference by 9.0 cm, and hip circumfer-
ence by 6.3 cm. All motor capabilities statistically significant improved (average
improvements: sit and reach test – 6.5 cm, shoulder flexibility – 3.7 cm, push-
ups – 12.1 repetitions, pull-ups – 2.3 repetitions, sit-ups – 15.3 repetitions, the
strength of hip ad back extensors – 53.2 s, squats – 19.2 repetitions, plank test
– 37.2 repetitions and YMCA 3-min stepping test – 11.6 heart rate per minute).
The psychological well-being of test subjects has also improved (positive self-
image, quality of sleep…).
Discussion and conclusion: A limitation of the study is the sample size and the
absence of a control group but anyway we found that a regular physical activity
has had positive effects on weight loss, motor capabilities, physical characteris-
tics and psychological conditions consequently a better quality of life.
Key words: obesity, regular exercise, weight loss, psychological condition
