Clinical Trial Summary
The aim of this study is to investigate the effects of 16-week CT on physical fitness
parameters, pulmonary function, and quality of life in healthy women.
Description:
Circuit training (CT) is an important type of training that can combine different types of
exercises in a single form of training. This training is generally circular with the
different exercise stations it contains, so it is known as CT. The initial protocol of this
training, developed by researchers at the University of Leeds in 1953, consisted of 9 to 12
moderate intensity exercises (40% to 60% of 1RM) performed at different exercise stations and
with a specific repetition and duration. Nowadays, it is seen that this training is applied
in different intensities and protocols. Also, CT has gained popularity due to its
practicality and effectiveness and is preferred by all age groups in recent years.
CT can be applied in many sport settings and does not require expensive equipment. Also, this
training can be adjusted to any level of physical fitness and includes bodyweight exercises
and functional movements. This training generally includes aerobic and strengthening
exercises and improves musculoskeletal, cardiovascular and pulmonary functions. On the other
hand, CT allows individual interaction both between participants and between participants and
the sports or health professionals who provide this training. Lastly, the hallmark of CT is
that it includes different exercise stations and short rest periods without breaks and the
advantage of CT is that it effectively improves several parameters of physical fitness
simultaneously.
Current literature investigating the effects of CT on physical fitness parameters in
different populations is still emerging. However, it was seen that few studies focused on the
healthy women population. Also, it was concluded that these studies reported different
results regarding the effects of CT. Accordingly, it has been concluded that 6-week CT
improved lower and upper extremity muscle strength and endurance, but had no positive effect
on flexibility and body composition in healthy women. However, it has been reported that
12-week CT had no positive effect on body composition, knee flexor and extensor muscle
strength in healthy women. Lastly, it has been concluded that12-week of CT had positive
effects on body composition, and improved flexibility and lower extremity muscle strength in
healthy women. These results in the literature suggested there is no clear consensus on the
effects of CT on physical fitness parameters in healthy women.
Moreover, the fact that CT also includes aerobic exercises shows this training may also have
an effect on pulmonary function. In this context, previous studies reported the positive
effects of this training on pulmonary function in adolescent, professional volleyball
players, women with sarcopenia, and people with human immunodeficiency virus. However, there
is insufficient evidence regarding the effects of CT on pulmonary function in healthy women.
To the best of our knowledge, only one previous study reported the positive effects of CT on
some pulmonary function in healthy women. Accordingly, it is clear that studies is needed to
examine the effects of CT on pulmonary function on healthy women. This training may also
improve pulmonary function in healthy women by increasing the performance of the diaphragm
muscle through aerobic exercise. Moreover, these positive effects on pulmonary function may
also improve quality of life in healthy women. Lastly, similar to physical fitness
parameters, studies investigating the effects of CT on quality of life also included
different populations. However, it was concluded there were few studies that included healthy
women and the results of these studies differed.
Therefore, the aim of this study is to investigate the effects of 16-week CT on physical
fitness parameters, pulmonary function, and quality of life in healthy women. Also, the
investigators hypothesized that the 16-week CT would be positive effects on physical fitness
parameters, pulmonary function, and quality of life in healthy women.
