First and foremost the authors
have published in the wrong department for the journal to be appreciated. They
have published the article to the International Sports Science and Engineering
department. Thou the sports science colleges might appreciate the journal the
engineers might not. Unlike, Polsgrove
(2016) and his colleges whom published a journal titled “Impact of 10-weeks of yoga practice on flexibility
and balance of college athletes” which had published their journal to the
International Journal of Yoga Department where many people would appreciate the
work of the authors.
subjects that had been chosen are all students whom have participated in an
interschool yoga competition. As they are students whom are already involved in
the activity there would be no point of testing them as even the control group
would be practicing yoga there would be not much difference in the results.
Polsgrove’s (2016) journal the authors had picked college athletes and had
separated them into yoga group (YG) and non-yoga group (NYG) and thus the
effect of yoga can be clearly see the difference.
of the experiment were clear thou they have not mention on executing pre test
and post test. Moreover there is no statement of when and frequent in a week
the subjects would need to perform the yoga exercises.
another journal had stated specifically the duration and number of sessions the
participants would undergo. The journal from Polsgrove (2016) they had measured
the balance and flexibility while Baljinder (2011) measured balance and agility
which makes no sense from the activities that are benefited from the practice
yoga group (YG) was comprised soccer team players (mean age = 19.8 years, s =
1.05) while the non-yoga group (NYG) was comprised baseball team players (mean
age = 20.3 years, s = 1.06). During the same 10-week period, members of both
groups completed the regularly scheduled sport specific training sessions.
While much of the training for the two sports was mutually exclusive, common
activities included static stretching exercises, weight training, and running.
In addition to their regular training, the YG subjects took part in certified
instructor-led yoga sessions 2 mornings (Tuesday and Thursday) each week before
any other physical activity. During the hour-long sessions, the instructor
demonstrated the series of yoga postures that were then mimicked by the
subjects. Subjects in both groups were asked to not participate in any
additional training activities. Measures of flexibility, balance, and joint
angles (JA) were taken immediately before and shortly after the 10-week study.
According to Cole (2015) the
standard use of decimal places for mean is two decimal places, percentage is
one decimal place, standard deviation is one or two decimal places and t-test
is one decimal places. The journal thou had placed four decimal places which
seemed quite complicated and uninteresting to read.
for summary statistics
Use enough decimal
places to give either the SD to two significant digits, or the SE to one
significant digit (Hopkins, 2011).
Integers or one
decimal place for values under 10%. Values over 90% may need one decimal
place if their complement is informative. Use two or more decimal places only
if the range of values is less than 0.1%
Use enough decimal
places to give the SE to one or two significant digits. For a standardised
mean difference use one or two decimal places
As with the mean
One or two decimal
places, or more when very close to ±1
Round to two
significant digits if the leading non-zero digit is four or more, otherwise
round to three (the rule of four) (Wainer, 1997). Alternatively use one/two significant digits
rather than two/three. For ORs very close to 1 (eg, in logistic regression
with a continuous variable) use three decimal places or else report the log
OR×100 as the percentage odds to one decimal place (Cole, 2000).
One or two
significant digits (Hopkins,
One or two
Use the same rule
as for the corresponding effect size (be it mean, percentage, mean
difference, regression coefficient, correlation coefficient or risk ratio),
perhaps with one less significant digit
Test statistics: t, F, ?2, etc
Up to one decimal
place and up to two significant digits
Round up to one
significant digit, within the limits shown in the examples. The lower limit
may be smaller than 0.001, but never 0.000. For genome-wide association
studies use the power of 10 format
<0.001 6.10?9 (Cole, 2015) Example, of a Good Tabulated Data YG and NYG traditional measures (Polsgrove, 2016) Discussion Discussion of the journal was too brief. The discussions of the results were only supported with journals related to the subject and no further explanation was given. In addition, one of their discussion's references was outdated as it was taken from the 1975 by Lerne. Moreover there is not much scientific explanation included in the discussion. The discussion of Dr. Baljinder (2011) included; "Yoga asanas are psychophysical practices to culture body and mind. Yoga practices are known to significantly improve health status, and reduce stress and anxiety (Hancock, 2007)", Hatha-yoga exercises provided regular functioning of principal bodily functions thus fostering a psychophysical balance; moreover, transcendental meditation increased aerobic metabolism, counteracting anaerobic metabolism which was related to mental distress (Lerne, 1975)" and "Yoga asanas were also shown to improve flexibility and health perception (Cowen, 2005)". As for an example of a journal by Polsgrove (2016) he had discussed about the possibilities that could have happened. Such as, "Because their regular practice of training activities (free weight training and practicing sport skills) challenged stability and balance, we expected that improvements in balance (Zech, 2010)", "In addition, because yoga practice has been shown to enhance the balance (Boehde, 2005)" and "Logically, training that emphasizes the multiple components of fitness at once should more readily enhance movement performance (Clark, 2012). Acknowledgement There were three authors whom have contributed to the journal but at the end of the journal there was brief information of the two of the authors and Dr. Wilfred Vaz(2011) was not included. This would be unfair to him as he also contributed to the research. Conclusion The overall journal is too brief and not specific enough. A better work could be done to perfect the journal.
