"Journal of Clinical and Diagnostic Research is at present a well-known Indian originated scientific journal which started with a humble beginning. I have been associated with this journal since many years. I appreciate the Editor, Dr. Hemant Jain, for his constant effort in bringing up this journal to the present status right from the scratch. The journal is multidisciplinary. It encourages in publishing the scientific articles from postgraduates and also the beginners who start their career. At the same time the journal also caters for the high quality articles from specialty and super-specialty researchers. Hence it provides a platform for the scientist and researchers to publish. The other aspect of it is, the readers get the information regarding the most recent developments in science which can be used for teaching, research, treating patients and to some extent take preventive measures against certain diseases. The journal is contributing immensely to the society at national and international level."

" Journal of Clinical and Diagnostic Research (JCDR) is a multi-specialty medical and dental journal publishing high quality research articles in almost all branches of medicine. The quality of printing of figures and tables is excellent and comparable to any International journal. An added advantage is nominal publication charges and monthly issue of the journal and more chances of an article being accepted for publication. Moreover being a multi-specialty journal an article concerning a particular specialty has a wider reach of readers of other related specialties also. As an author and reviewer for several years I find this Journal most suitable and highly recommend this Journal."

Dr. Mamta Gupta,
"It gives me great pleasure to be associated with JCDR, since last 2-3 years. Since then I have authored, co-authored and reviewed about 25 articles in JCDR. I thank JCDR for giving me an opportunity to improve my own skills as an author and a reviewer.
It 's a multispecialty journal, publishing high quality articles. It gives a platform to the authors to publish their research work which can be available for everyone across the globe to read. The best thing about JCDR is that the full articles of all medical specialties are available as pdf/html for reading free of cost or without institutional subscription, which is not there for other journals. For those who have problem in writing manuscript or do statistical work, JCDR comes for their rescue.
The journal has a monthly publication and the articles are published quite fast. In time compared to other journals. The on-line first publication is also a great advantage and facility to review one's own articles before going to print. The response to any query and permission if required, is quite fast; this is quite commendable. I have a very good experience about seeking quick permission for quoting a photograph (Fig.) from a JCDR article for my chapter authored in an E book. I never thought it would be so easy. No hassles.
Reviewing articles is no less a pain staking process and requires in depth perception, knowledge about the topic for review. It requires time and concentration, yet I enjoy doing it. The JCDR website especially for the reviewers is quite user friendly. My suggestions for improving the journal is, more strict review process, so that only high quality articles are published. I find a a good number of articles in Obst. Gynae, hence, a new journal for this specialty titled JCDR-OG can be started. May be a bimonthly or quarterly publication to begin with. Only selected articles should find a place in it.
An yearly reward for the best article authored can also incentivize the authors. Though the process of finding the best article will be not be very easy. I do not know how reviewing process can be improved. If an article is being reviewed by two reviewers, then opinion of one can be communicated to the other or the final opinion of the editor can be communicated to the reviewer if requested for. This will help one’s reviewing skills.
My best wishes to Dr. Hemant Jain and all the editorial staff of JCDR for their untiring efforts to bring out this journal. I strongly recommend medical fraternity to publish their valuable research work in this esteemed journal, JCDR".

"I wish to thank Dr. Hemant Jain, Editor-in-Chief Journal of Clinical and Diagnostic Research (JCDR), for asking me to write up few words.
Writing is the representation of language in a textual medium i e; into the words and sentences on paper. Quality medical manuscript writing in particular, demands not only a high-quality research, but also requires accurate and concise communication of findings and conclusions, with adherence to particular journal guidelines. In medical field whether working in teaching, private, or in corporate institution, everyone wants to excel in his / her own field and get recognised by making manuscripts publication.


Authors are the souls of any journal, and deserve much respect. To publish a journal manuscripts are needed from authors. Authors have a great responsibility for producing facts of their work in terms of number and results truthfully and an individual honesty is expected from authors in this regards. Both ways its true "No authors-No manuscripts-No journals" and "No journals–No manuscripts–No authors". Reviewing a manuscript is also a very responsible and important task of any peer-reviewed journal and to be taken seriously. It needs knowledge on the subject, sincerity, honesty and determination. Although the process of reviewing a manuscript is a time consuming task butit is expected to give one's best remarks within the time frame of the journal.
Salient features of the JCDR: It is a biomedical, multidisciplinary (including all medical and dental specialities), e-journal, with wide scope and extensive author support. At the same time, a free text of manuscript is available in HTML and PDF format. There is fast growing authorship and readership with JCDR as this can be judged by the number of articles published in it i e; in Feb 2007 of its first issue, it contained 5 articles only, and now in its recent volume published in April 2011, it contained 67 manuscripts. This e-journal is fulfilling the commitments and objectives sincerely, (as stated by Editor-in-chief in his preface to first edition) i e; to encourage physicians through the internet, especially from the developing countries who witness a spectrum of disease and acquire a wealth of knowledge to publish their experiences to benefit the medical community in patients care. I also feel that many of us have work of substance, newer ideas, adequate clinical materials but poor in medical writing and hesitation to submit the work and need help. JCDR provides authors help in this regards.
Timely publication of journal: Publication of manuscripts and bringing out the issue in time is one of the positive aspects of JCDR and is possible with strong support team in terms of peer reviewers, proof reading, language check, computer operators, etc. This is one of the great reasons for authors to submit their work with JCDR. Another best part of JCDR is "Online first Publications" facilities available for the authors. This facility not only provides the prompt publications of the manuscripts but at the same time also early availability of the manuscripts for the readers.
Indexation and online availability: Indexation transforms the journal in some sense from its local ownership to the worldwide professional community and to the public.JCDR is indexed with Embase & EMbiology, Google Scholar, Index Copernicus, Chemical Abstracts Service, Journal seek Database, Indian Science Abstracts, to name few of them. Manuscriptspublished in JCDR are available on major search engines ie; google, yahoo, msn.
In the era of fast growing newer technologies, and in computer and internet friendly environment the manuscripts preparation, submission, review, revision, etc and all can be done and checked with a click from all corer of the world, at any time. Of course there is always a scope for improvement in every field and none is perfect. To progress, one needs to identify the areas of one's weakness and to strengthen them.
It is well said that "happy beginning is half done" and it fits perfectly with JCDR. It has grown considerably and I feel it has already grown up from its infancy to adolescence, achieving the status of standard online e-journal form Indian continent since its inception in Feb 2007. This had been made possible due to the efforts and the hard work put in it. The way the JCDR is improving with every new volume, with good quality original manuscripts, makes it a quality journal for readers. I must thank and congratulate Dr Hemant Jain, Editor-in-Chief JCDR and his team for their sincere efforts, dedication, and determination for making JCDR a fast growing journal.
Every one of us: authors, reviewers, editors, and publisher are responsible for enhancing the stature of the journal. I wish for a great success for JCDR."

Dr. Shankar P.R.

"On looking back through my Gmail archives after being requested by the journal to write a short editorial about my experiences of publishing with the Journal of Clinical and Diagnostic Research (JCDR), I came across an e-mail from Dr. Hemant Jain, Editor, in March 2007, which introduced the new electronic journal. The main features of the journal which were outlined in the e-mail were extensive author support, cash rewards, the peer review process, and other salient features of the journal.
Over a span of over four years, we (I and my colleagues) have published around 25 articles in the journal. In this editorial, I plan to briefly discuss my experiences of publishing with JCDR and the strengths of the journal and to finally address the areas for improvement.
My experiences of publishing with JCDR: Overall, my experiences of publishing withJCDR have been positive. The best point about the journal is that it responds to queries from the author. This may seem to be simple and not too much to ask for, but unfortunately, many journals in the subcontinent and from many developing countries do not respond or they respond with a long delay to the queries from the authors 1. The reasons could be many, including lack of optimal secretarial and other support. Another problem with many journals is the slowness of the review process. Editorial processing and peer review can take anywhere between a year to two years with some journals. Also, some journals do not keep the contributors informed about the progress of the review process. Due to the long review process, the articles can lose their relevance and topicality. A major benefit with JCDR is the timeliness and promptness of its response. In Dr Jain's e-mail which was sent to me in 2007, before the introduction of the Pre-publishing system, he had stated that he had received my submission and that he would get back to me within seven days and he did!
Most of the manuscripts are published within 3 to 4 months of their submission if they are found to be suitable after the review process. JCDR is published bimonthly and the accepted articles were usually published in the next issue. Recently, due to the increased volume of the submissions, the review process has become slower and it ?? Section can take from 4 to 6 months for the articles to be reviewed. The journal has an extensive author support system and it has recently introduced a paid expedited review process. The journal also mentions the average time for processing the manuscript under different submission systems - regular submission and expedited review.
Strengths of the journal: The journal has an online first facility in which the accepted manuscripts may be published on the website before being included in a regular issue of the journal. This cuts down the time between their acceptance and the publication. The journal is indexed in many databases, though not in PubMed. The editorial board should now take steps to index the journal in PubMed. The journal has a system of notifying readers through e-mail when a new issue is released. Also, the articles are available in both the HTML and the PDF formats. I especially like the new and colorful page format of the journal. Also, the access statistics of the articles are available. The prepublication and the manuscript tracking system are also helpful for the authors.
Areas for improvement: In certain cases, I felt that the peer review process of the manuscripts was not up to international standards and that it should be strengthened. Also, the number of manuscripts in an issue is high and it may be difficult for readers to go through all of them. The journal can consider tightening of the peer review process and increasing the quality standards for the acceptance of the manuscripts. I faced occasional problems with the online manuscript submission (Pre-publishing) system, which have to be addressed.
Overall, the publishing process with JCDR has been smooth, quick and relatively hassle free and I can recommend other authors to consider the journal as an outlet for their work."

Abstract

Introduction: Yoga has proven to improve spiritual as well as psychophysiological behaviour of a human being. This helps them to perform better in their game improving abdominal strength and gives benefits to every player’s need. It also helps improve both physical and mental health.

Aim: To analyse the effects of yogic breathing manoeuvre on pulmonary functions and VO2 max in male football players.

Materials and Methods: This quasi-experimental study was conducted in Department of Physiotherapy, School of Physiotherapy at D.Y. Patil University, Navi Mumbai, Maharashtra, India, from February 2019 to February 2020. The study included 60 male players within the age group from 18-25 years with at least 2 years of experience. They were divided into two groups - group A was experimental group and group B was control group. Group A performed pranayama along with routine football specific training and group B performed only football specific training for six weeks. Pre and post values for pulmonary functions and VO2 max were taken by Pulmonary Function Test (PFT) and Queens College step test as outcome measures. The data was analysed using Independent t-test.

Results: Mean age of group A and group B was 19.7±1.69 years and 20.6±1.89 years, respectively. After doing yogic breathing maneuvers for 6 weeks, there was a significant (p-value<0.001) improvement in pulmonary function and VO2 max values in male football players for experimental group as compared to control group. The mean difference for Forced Expiratory Volume in 1 second (FEV1) was 0.3% and 0.13% and for VO2 max was 0.71 mL/kg/min and 2.71 mL/kg/min for control and experimental group respectively.

Conclusion: Implementing regular practice of yogic breathing manoeuvre along with football training improves pulmonary functions of the football players.

Football has become a sport that interests all population worldwide. The game demands different skills of rapid acceleration or deceleration, short sprints, jumping, turning, kicking and tackling while playing (1). Yoga, for a fact, helps player to perform better in their game. Yoga is an ancient science and in these recent years it has become popular all over the world. Yoga techniques include combination of pranayamas (voluntary breathing exercises), dhyana (meditations), and asanas (specific posture). Yoga training includes complex forms of breathing pattern, but the soul of its practice is the powerful bridge between body and mind (2),(3). Pranayama is a deep breathing technique, which decreases the work of breathing and reduces the dead space ventilation. Regular practice of pranayama enhances physical and mental health, improves autonomic tone and reduces the result of stress and strain on the body (4).

Kapalbhati, Bhastrika, Bharamari, Nadi and Sadhana are the various types of pranayama amongst practitioners (5). The Sanskrit word Kapalbhati is made up of two words in which kapal means forehead or skull and bhati means light, illuminating, shining (6). Bharamari pranayama is one of the ancient yogic breathing techniques which has proven that it reduces cardiovascular reactivity to stress. Bhastrika pranayama is a Sanskrit word which means breathing like bellows. Bellows was a device which was used to fan fire for producing a strong current of air in ancient days (7).

It has been seen that pulmonary functions provides important clinical information to quantify and identify the defects and abnormalities in the functions of respiratory system (8). It has been seen that the strength and exercise performance can be dependent on respiratory system of a trained athlete. The gold standard for assessing the cardiorespiratory endurance of a person is by measuring maximal oxygen consumption which is interpreted as VO2 max. There are various direct and indirect methods used to assess VO2 max in which Queens College step test uses the prediction equation and uses heart rate. It is not time consuming and does not need any trained personnel (9),(10).

In view of the above background, there is no literature available on the effects of Kapalbhati, Bharamari and Bhastrika on pulmonary function and VO2 max in footballers. Thus, the aim of this study was to evaluate the effects of yogic breathing manoeuvres on pulmonary functions in football players.

Material and Methods

This quasi-experimental study was conducted in Department of Physiotherapy, School of Physiotherapy at D.Y. Patil University, Navi Mumbai, Maharashtra, India, from February 2019 to February 2020. The study included 60 male players within the age group from 18-25 years with at least 2 years of experience. Ethical clearance was obtained from Institutional Ethics Committee of DY Patil University, Navi Mumbai (Ref. No.- DYPUSOP/313(a)/2018 dated 14th December 2018).

Sixty football players were selected from different football clubs of Navi Mumbai, who participated in the study by convenient sampling. They were divided into two groups:

• Group A- Experimental group (n=30)
• Group B- Control group (n=30)

Sample size calculation: The formula used was (11),(12):

η≥ *Z (1-α/2) + Z (1-β){ 2 *(σ1)2+ (σ2)2}/ {μ12}2

Z1-α/2=1.96 (95% CJ or 5 % LS)
Z1-β=0.84 (80% power)
σ1= Standard deviation of experimental
σ2=Standard deviation of control
μ12=difference in mean of experimental group and control group.


The final Mean sample of 30 per group was obtained.

Inclusion criteria: Male football players within the age group from18 to 25 years, with at least two years of experience were included in the study.

Exclusion criteria: Subject with any musculoskeletal disorder, female participants, and those with history of allergy that would affect breathing were excluded from the study.

Procedure

Subjects were explained about the procedure of the study, and a written consent was obtained from them. The data collected were age, gender, height, weight, Body Mass Index (BMI). For the experimental group pranayama session lasted for 15-20 minutes, three days a week for a total of six weeks. These sessions were conducted along with their routine football specific training. The control group received only their routine football specific training.

Pre-test, and post-test parameters (after six weeks) for all 60 samples were recorded which included Pulmonary Function Tests (PFT) values:

A-Using portable PFT device

• Forced expiratory volume in the first second (FEV1) -in percentage
• Forced Vital Capacity (FVC) -in Litre
• FEV1/FVC
• Peak Expiratory Flow Rate (PEFR) - L/min

B- Queens College step test

• Maximum amount of oxygen uptake (VO2 max)- in mL/kg/min

Pulmonary function tests: PFT were performed with a portable spirometer, with the subject sitting in a comfortable chair or stool. The test was repeated for at least three times, and the highest value was considered for the analysis.

Queen’s College step test: It was assessed to measure VO2 max in which maximum oxygen uptake of an individual was seen. The height of the step was 16.25 inches (41.3 cm), and a total duration of 3 minutes, at the rate of 24 cycles per minute, was set by a metronome. The subjects were asked to warm up for 10 minutes before the test, and the command was given for starting the test as “GO? with stopwatch timer on. It was ensured that every subject maintains the required pace for three minutes (13).

After completion of the exercise, within the recovery period the carotid pulse rate was measured for 5-20 seconds in the standing position. This pulse rate was converted into beats per minute and the following equation was used to predict the maximum oxygen uptake capacity:

PVO2max (ml/kg/min) = 111.33-(0.42 × pulse rate in beats/min) (13):

Yogic Breathing Exercise

After initial recordings of the above-mentioned test, yoga breathing exercises were conducted during the evening practice session in small groups of 5-6 people. Every subject was put into daily practice of yoga breathing exercises (pranayama) for five minutes of each technique. Three pranayama techniques used were: Bhastrika, Bhramari and Kapalbhati (Table/Fig 1) (5),(7),(8),(9).

Players were instructed to sit in a comfortable pose sidhasna or sukhasana (ease pose) with erect spine for all the three techniques.

Bhastrika pranayama: In Bhastrika pranayama (Bellow breathe) players were taught to inhale deeply through nostrils, forcing the diaphragm move down and outwards, expanding the lungs as much as possible, feeling the collar bone rising up and exhaling out quickly through nostrils (which will drop the collar bone). The inflated chest and abdomen starting to shrink as the lung collapse. The process of exhalation was faster than inhalation in this technique (7).

Bhramari pranayama: In Bhramari pranayama (Bee Breathe), players were told to close their eyes by placing the index fingers on forehead and remaining fingers along the sides of nose below eye and near nostrils. After deep inhalation, tip of fingers were used for closing the nostrils to keep the lungs filled, and then exhaling through the nose with humming sound was originated from the throat (OM chanting) (8).

Kapalbhati Pranayama

For Kapalbhati pranayama (shinning forehead breath), nasal inspiration was taken through the nose and forceful expiration was done by pulling in the stomach muscles as this placed the emphasis of the breathing on exhalation rather than inhalation. Exhalation time was less than inhalation time. While exhaling, the proper contraction of stomach muscles were noted which helped to push the air out (9).

Statistical Analysis

After 6 weeks the data was analysed using Statistical Package for the Social Science (SPSS) version 16.0 software. The confidence interval was set at 95% and Chi-square test and Independent T-Test was done. The p-value<0.05 was considered significant.

Results

Mean age of group A and group B was 19.7±1.69 years and 20.6±1.89 years, respectively. Height (cm) and weight (kg) for group A was 167.9±6.53 cm and 61.23±6.53 kg and for group B was 166.86±5.98 cm and 60.6±4.08 kg, respectively. Body Mass Index (BMI) for group A was 21.83±1.3 kg/m2 and for group B was 21.76±0.9 kg/m2 (Table/Fig 2). Comparison of mean and SD of PFT functions and VO2 max at pre and post between experimental and control groups is presented in (Table/Fig 3).

When mean difference (pre and post intervention) was compared between control and experimental group, FVC, PEFR and VO2 max were seen to be significant whereas FEV1 and FEV1/FVC were non significant (Table/Fig 4).

Discussion

In the Indian philosophy, the liberation of soul through perfection is the goal of all the orthodox systems. Yoga is an ancient Indian practice which includes varieties of exercises and breathing techniques which causes betterment of proper health and lung functions. Pranayama is a part of yoga which consists of breathing techniques which can be practiced in slow or fast manner and has three periods: purak(inhalation), kumbhak(retention) and recheck (exhalation) [6,8,11].

The result of this study showed a significant difference with an increase in pulmonary function post intervention in male football players of both experimental and control groups. The above findings were supported by the study from Mooventhan A and Khode V, who concluded that that Bhramari pranayama and OM chanting are used to raise energy levels, calm the body, increase respiratory stamina, relaxing the chest and expanding the lung. Slow and deep breathing exercise reduces the dead space ventilation and restores the air throughout the lungs. During pranayama, the pulmonary stretch receptors are stimulated when the lung is inflated to the maximum. This in turn improves the FEV1 as the stretch receptors decreases the tracheobronchial smooth muscle tone, sequentially decreasing air resistance and increasing airway caliber (8).

Bamne SN concluded that in Bhastrika pranayama, the lung fields are filled and emptied completely and efficiently which increases the strength in respiratory muscles particularly diaphragm. When the lungs are filled there is release of surfactant and prostaglandins in alveolar spaces which decrease the bronchioles smooth muscle tone and increases lung compliance respectively (7). Similarly in this study, the pulmonary functions improved in the experimental group.

Dinesh T et al., had studied the effect of Kapalbhati pranayama on pulmonary function. They concluded that Kapalbhati pranayama demands breathe coordination at higher rate and therefore requiring higher rate of respiratory muscle activity (4). In Kapalbhati pranayama there is powerful contraction of the abdominal muscles mainly the external and internal obliques, transverse abdominis and rectus abdominis during force exhalation. Oxygen consumption rates are approximately 1.1-1.8 times higher during Kapalbhati techniques compared to sitting quietly. Rapid Kapalbhati pranayama maintains acid-base balance by making dead space of the lungs active and hence increasing oxygenation of tissues and cleaning the whole body (14).

As players have higher values of lung function compared to normal individuals, regular prolonged forceful inspiration and expiration can lead to increase in respiratory muscle strengthening which helps lungs to inflate and deflate to its maximum capacity. There are rhythmic diaphragmatic movements in improvement of blood circulation of heart and lung muscles [15,16]. Increase in VO2 max indicates increased oxygen consumption by muscle and decreases in the vascular tone which in turn results in stimulation of parasympathetic activity [17,18]. In the present study, the control group showed significant difference in the values of pulmonary function and VO2 max due to their regular football specific training. But in the experimental group who were given pranayama techniques along with the football specific training, improvement was observed more than the control group.

The pranayama technique used in this study (bhastrika, bhramari, Kapalbhati) can be used in many sports which mainly focus on the aerobic endurance such as basketball, throwball. It can also be used in anaerobic training such as weight lifting, sprinting, high intensity interval training which involves short, intense burst of physical activities. Now-a-days due to excess of pollution, breathing is getting affected due to less amount of fresh air inspired, which leads to many diseases and lung conditions affecting our lung capacity [19,20]. The yogic breathing manoeuvre can also be incorporated in regular training for other sports as well to reduce the risk of injury and to improve the pulmonary function of a player.

Limitation(s)

In this study the age group that was considered was limited. Moreover, only male club football players who were into the regular practice were included. More studies involving both the gender and a wider age group must be performed.

Conclusion

It can be concluded that a six weeks of yogic breathing manoeuvre lead to an increase in pulmonary function and VO2 max in male football players. This suggests that yogic breathing manoeuvre can be added in training programs, along with aerobic and anaerobic exercises for improvement in the pulmonary function capacity of the players.

Author contributions: SJ has been involved in the conceptualization of the study and data collection, SP contributed towards the methodology and the discussion part, JP contributed towards analysis and writing of the manuscript. All the authors collectively contributed their valuable work for the final manuscript.
