Abstract
The purpose of the study was to study the comparative trend of pracchardana and vi dharna
effect on negative breath holding capacity of school going children before and after experimentation.
A total of 30 subjects with a ge ranging from 13 to 17 years were selected. Practice of
pracchardana
and
vidharna
were considered as independent variables and negative breath holding capacity was
considered as dependent variables. Time series research design was adapted for the purpose of the
study in which observations were taken on eight occasions before and after activation of independent
variables. P ractice was given 5 days a week, 45 minutes for each day. Three sets of practice were
performed in each session. Trend analysis (trial means: one standard condition) was performed. It
was concluded that: (1) insignificant trend (1.418, p >0.05) was found before experimental treatme nt
on negative breath holding capacity of school going children; (2) linear (2.919, p >0.05 ) and quadratic
(0.113, p > .05) trend be fore experimental treatment on negative breath holding capacity of school
going children were found insignificant; (3) significant trend (248.066, p <0.05) of the effect of
experimental treatment was found on negative breath holding capacity of scho ol going children; (4)
linear trend (455.431, p <0.05) during experimental treatment on negative breath holding capacity of
school going children was found significant; (5) quadratic (0.856, p >0.05) trend during experimental
treatment on negative breath holding capacity of school going children was found insignificant; (6)
cubic (4.380, p <0.05) trend during experimental treatment on negative breath holding capacity of
school going children was found significant; (7) significant trend (65.072, p <0.05) was found after
experimental treatment on negative breath holding capacity of school going children; (8) linear (111.9,
p <0.05) trend after experimental treatment on negative breath holding capacity of school going
children was found significant; (9) quadratic (0.227, p>0.05) trend after experimental treatment on
negative breath holding capacity of school going children was found significant.
Key wo rds:
Pracchardana
,
Vidharna
and negative breath holding capacity.
Introduction
Pracchardana
is expulsion;
vidharana
is
retention. The expulsion and the retention of the
breath are supposed to be one of the means of
bringing about composure of mind. The mind may
also be calmed by expulsion and retention of the
breath.
Objectives
To study the trend of effect of pracchardana
and vidharna on Negative breath holding
capacity of school going children.
To study the trend before experimental
treatment on negative breath holding
capacity of school going children.

Experimental
Subjects
A total of 30 subjects with age ranging from
13 to 17 years were selected from The Aryan
International School, Varanasi. All the subjects
were selected randomly.
Variables
Practice of
Pracchardana
and
Vidharna
were considered as independent variables and
negative breath holding capacity was considered
as dependent variables.
Experimental Design
Time series research design1 was adapted
for the purpose of the study in which observations
were taken on eight occasions before and after
activation of independent variables.

O = Observation, X = Treatment
All the 30 subjects were participated in the

fo r 6 wee k s.
Observations were taken eight times i.e. three
observations before the treatment and five after
treatment application. All the observations were
recorded at two weeks interval time.
Treatment
Practice was given 5 days a week, 45
minutes for each day. Three sets of practice were
performed in each session. After each repetition of
pracchardana
,
vidharna
was performed for 10
seconds as shown below.

Statistical Analysis
To study the trend of
pracchardana
and
vidharna
before experimental treatment, in the
linear curve, quadratic curve, cubic curve and after
the experiment, on negative breath holding capacity
of school going children, trend analysis (trial means:
one standard condition) was applied2,3. The level of
significance was set at 0.05 level.
Results and Discussion
In descriptive statistics, mean, standard
deviation, skewness, standard error of skewness,
kurtosis and standard error of kurtosis were
calculated. In case of age, when numerical value of
skewness was compared with twice the standard
error of skewness and included the range from
minus twice the standard error of skewness to plus
twice the standard error of skewness. The value of
skewness lies within this range. This shows that
data or degree of skewness is not significantly
skewed or skewness is considered not seriously
violated. The same numerical process was used to
check the normal distr ibution in relatio n to
kurtosis. Again a range of normality by multiplying
the standard error of kurtosis by 2 was constructed
fr o m mi n u s va lue to pl u s th at value. This
distribution is also significantly normal in terms of
kurtosis.
It is evident from Table -2 that insignificant
trend was found before experimental treatment on
negative breath holding capacity of school going
children.
Li n ear and quadratic tr en d before
experimental treatment on negative breath holding
capacity of school going children were also found
insignificant (Table 3).
On the other hand significant trend of the
effect of experimental treatment was found on
negative breath holding capacity of school going
children (Table 4).

It is evident from Table -6 that significant
trend was found after experimental treatment on
negative breath holding capacity of school going
children. After treatments application linear trend
was found significant but quadratic trend was

nonsignificant (Table 7). Trends between breath
holding capacity and observations before, during
and after experimental treatments are shown in
Figures 1, 2 and 3.
Physiological changes associated with yoga
training caused improvements in ventilatory
functions of the lungs including a prolongation of
breath holding times4. Changes in cardiorespiratory
an d meta bo l ic in t e n s ity by th e practice of
pranayamas and meditation were also reported5-7.
Increase in vital capacity increase and chest
circumference concludes that yoga training has a
strong effect on ou r respiratory system and
ventilatory functions. A smaller proportion of lipids
wa s metaboli zed durin g meditation practice
compared with rest8. In the present study change
in ne g ative br e ath hol d ing capa c i ty due to
pracchardana and vidharna practice might be due
to change in oxygen uptake (VO2) and the carbon
dioxide output (VCO2).
