Abstract— The game of Volleyball was invented a long way
since 1895 when W. G. Morgan hang a tennis net six feet
across the Holyoke “Y” gym and volleyed a basketball
bladder back and forth and named it as “mignonette.
Initially, the game was managed by Indian Olympic
Association and the Interstate volleyball Championship was
conducted every two years between the years 1936 and
1950.The purposes of the study were to find out the
relationship of growth status between the variables of U-14
years and U-19 years groups. Sixty two (62) male subjects
were selected for this study. Among them, thirty one (31)
male subjects for U-14 and thirty one (31) male subjects for
U-19 years groups. Findings revealed that the relationship
between variables of the three growth variables, relationship
existed in all of the two age groups except in height and
BMI of two groups.
Key Words: Volleyball, growth status, U-14 years, and U-
19, BMI
I. INTRODUCTION
A. General Introduction:
The game of Volleyball was invented a long way since 1895
when W. G. Morgan hang a tennis net six feet across the
Holyoke “Y” gym and volleyed a basketball bladder back
and forth and named it as “mignonette “. Later Dr. L. H.
Gulick and Dr. A. T. Holsteat of Springfield College noted
the nature of play “volling the ball” and named it as
“Volleyball”.
On July 7, 1896 at Springfield College the first game of
Volleyball was played
In 1900 a special ball was designed for the sports.
In 1916 in the Philippines and offensive style of passing that
ball in high trajectory to be struck by another player (the set
and spike were introduced).
In 1017 the game was changed from 21 to 15 points.
In 1920 three hits per side and back row attack rules were in
titivated.
In 1930 the first two man beach game was played.
In 1934 the approval and recognition of National Volleyball
referees.
In 1947 the FIBV was found.
In 1949 the initial World Championships were held in
Prague, Czechoslovakia.
In 1964, Volley was introduced two the Olympic Game in
Tokyo.
In 1986 the Women’s professional Volleyball Association
(WPVA) was formed.
In 1988 US men repeated the gold in the Olympics in Korea.
In 1990 the world league was created.
In 1995 the sports of Volleyball was hundred years old.
In 1996 two person beach Volleyball was added to the
Olympic.
B. History of Volleyball in India:
The Y.M.C.A. College of physical education in Madras
(now Chennai) first began training its students in the sport,
which then eventually spread to other parts of the country.
Initially, the game was managed by Indian Olympic
Association and the Interstate volleyball Championship was
conducted every two years between the years 1936 and
1950. In the year 1951 the Volley Federation of India was
establish. After India independence, the first Indian National
Championship was organized in 1952 at Chennai. The
Indian volleyball team won gold medal in 1955 at the
International Asian Meet held at Japan.
C. BMI & Growth:
The Body Mass Index (BMI) is a heuristic proxy from
human body fat based on individuals’ weight and height.
BMI does not actually measure the percentage of body fat. It
was devised between 1930 and 1950 by the Belgian
Polymath Adolph Quetelet during the course of developing
social physics. BMI is defined as the individual’s body mass
divided the square of his or her height. The formula
universally used in medicine produced unit measures of
kg/m2.
BMI= {Mass (in kg)/Height (in m)2
}
Growth: Growth refers to an increase in sum quantity over
time. The quantity can be:
Physical (e.g. growth in height, growth in weight)
Abstract (e.g. a system becoming more complex, an
organism becoming more mature )
Growth, body composition influenced by complex
interactions between genetic and environmental factors,
which include nutrition, exercise and other aspect of
lifestyle. Growth status changes with the change of age
(male up to 25 and female up to 21). Puberty is a time of
rapid change in size, shape and body composition for both
sexes.
Vo2 max:
Vo2 max (also maximal oxygen consumption, maximal
oxygen uptake, peak oxygen uptake or maximal aerobic
capacity) is the maximum capacity of an individual’s body
to transport and use oxygen during incremental exercise,
which reflects the physical fitness of the individual. The
name is derived from v- volume, o2- oxygen and max –
maximum.

Vo2 max is expressed either as an absolute rate in litters of
oxygen per minute (l/min) or as a relative rate in millilitres
of oxygen per kilogram of body weight per minute
(ml/kg/min). The litter expression is often used to compare
the performance of endurance sport athletes. It depends
upon some factors –
i. Type of exercise,
ii. Intensity of load
iii. Duration
iv. The person (age, sex, trained, un-trained, health
etc.) e.g. at rest 200-300 ml/min (male),
(Absolute unit) During Exercise
Untrained Trained
3-3.5lit/min 4.5-5lit/min
(Relative unit) Vo2 max = ml/min/kg
At Rest-200/LBM (if 50kg) = 4ml/min/kg
During Exercise Untrained Trained
40ml/min/kg 60-80ml/min/kg
There is a close relationship between body composition
(LBM) and oxygen consumption. The greater proportion
LBM, the greater the maximal oxygen consumption both
absolutely and kilogram body weight.
D. Flexibility:
Flexibility or limberness refers to the absolute range of
motion in a joint or series of joint, and length in muscles that
cross the joint. Flexibility is variable between individuals,
particularly in terms of differences in muscle length of
multi-joint muscles. There are two kinds of flexibility, static
and dynamic flexibility.
Static:-The range of motion about a joint is defining static
flexibility.
1) Dynamic:-
This type of flexibility is defined as the opposition or
resistance of a joint to motion. The structural limits to
flexibility are bone, muscle, ligaments, other structures
associated with the joint capsule, tendons and other
connective tissues and skin. Flexibility is improved by type
of exercise and stretching.
Along with strength and endurance, flexibility is
also an important component of muscular performance. So
Flexibility is very important of any type of activities. In
volleyballs more required shoulder wrist, waist, flexibility
and other flexibility of the joint.
II. METHODOLOGY
In this chapter procedures for collecting data and procedures
for analysis have been discussed. This chapter deals with the
subject, test, measurement, conducted; sample procedure
tools used collection of data criterion measures method
adopted for data collection.
A. SUBJECT:
The subjects of the present study were U-14 and U-19
district level male Volleyball players selected from
Mushidabad, Basanta Sangha, Katwa Athletic Club and
Tarun Sangha. Sixty two (62) male subjects were selected
for this study. Among them, thirty one (31) male subjects
for U-14 and thirty one (31) male subjects for U-19 years
groups.
1) CRITERION MEASURES:
To conduct the present study the following
measurements were taken –
a) Age
b) Height
c) Weight
d) BMI
e) Flexibility
f) Vo2 max.
2) TOOLS AND EQUIPMENT USED:
For measuring, Height, Weight, flexibility and Vo2 max. the
following instruments and tools were used –
a) Measuring tape (Stadiometer)
b) Weighing Machine
c) Flexometer
d) Stopwatch
e) Bench
f) Metronome.
3) PROCEDURE OF DATA COLLECTION:
The Age, Height, Weight, Flexibility and Vo2 max. of the
subjects were measured in the following ways-
a) Age: Age was recorded in completed year. The
evidence regarding proof of age was gathered from
Birth Certificate for the respective players.
b) Height: The height was measured on a standard
scale the reading of the scale taken in nearest
centimeters.
c) Weight: The weights of the subjects were recorded
by the weighing machine.
d) BMI: BMI (Body Mass Index) was measured by
using this formula
Weight (in kg)
BMI= (Height in meter )2
e) Flexibility: Indirect method of flexibility was
measured by sit and reach test. Hip and back flexion as
well as extension of the hamstring muscles was
measured through this test. The reliability of this were
recorded from separate testing and correlated. A twelve
(12inch) mark scale was used form a wooden box
(Flexometer) and subject was directed to a long sitting
position. Maximum reach by their fingertips were
recorded as their flexibility.
f) Vo2 max: Vo2 max was measured with the help of
Queen’s College Step Test. The test consisted of
stepping up and down on the bench (16.25’’ height) for
3 minutes. The cadence of 24 steps per min. is
established by setting the metronome at 96 bpm. At the
end of the time period the subjects remain sitting on the
bench. Than we were counted pulse rate for a 15 sec.
internal beginning 5sce.after the session of exercise.
The score is total no. of pulse rate per minute.
To measure the Vo2 max from this formula:
Male = {111.33-(0.42 X pulse rate per min.)} ml/kg/min.
III. RESULTS AND DISCUSSION
The collected data were classified and presented in this
chapter in the tabular form. The raw score were arranged
according to design of the study. Appropriate statistical
computation was made and computed score were presented
in this chapter.

Comparative study on growth status of Teen age Male Volleyball players on selected Physical and Physiological Parameters

  • 1. IJSRD - International Journal for Scientific Research & Development| Vol. 1, Issue 4, 2013 | ISSN (online): 2321-0613 All rights reserved by www.ijsrd.com 958 Comparative study on growth status of Teen age Male Volleyball players on selected Physical and Physiological Parameters Mr. Anirban Misra1 Dr. Sudip Sundar Das2 1 Research Scholar 2 Associate Professor & HOD 1, 2 Department of Physical Education 1, 2 Jadavpur University, Kolkata-700032, India Abstract— The game of Volleyball was invented a long way since 1895 when W. G. Morgan hang a tennis net six feet across the Holyoke “Y” gym and volleyed a basketball bladder back and forth and named it as “mignonette. Initially, the game was managed by Indian Olympic Association and the Interstate volleyball Championship was conducted every two years between the years 1936 and 1950.The purposes of the study were to find out the relationship of growth status between the variables of U-14 years and U-19 years groups. Sixty two (62) male subjects were selected for this study. Among them, thirty one (31) male subjects for U-14 and thirty one (31) male subjects for U-19 years groups. Findings revealed that the relationship between variables of the three growth variables, relationship existed in all of the two age groups except in height and BMI of two groups. Key Words: Volleyball, growth status, U-14 years, and U- 19, BMI I. INTRODUCTION A. General Introduction: The game of Volleyball was invented a long way since 1895 when W. G. Morgan hang a tennis net six feet across the Holyoke “Y” gym and volleyed a basketball bladder back and forth and named it as “mignonette “. Later Dr. L. H. Gulick and Dr. A. T. Holsteat of Springfield College noted the nature of play “volling the ball” and named it as “Volleyball”. On July 7, 1896 at Springfield College the first game of Volleyball was played In 1900 a special ball was designed for the sports. In 1916 in the Philippines and offensive style of passing that ball in high trajectory to be struck by another player (the set and spike were introduced). In 1017 the game was changed from 21 to 15 points. In 1920 three hits per side and back row attack rules were in titivated. In 1930 the first two man beach game was played. In 1934 the approval and recognition of National Volleyball referees. In 1947 the FIBV was found. In 1949 the initial World Championships were held in Prague, Czechoslovakia. In 1964, Volley was introduced two the Olympic Game in Tokyo. In 1986 the Women’s professional Volleyball Association (WPVA) was formed. In 1988 US men repeated the gold in the Olympics in Korea. In 1990 the world league was created. In 1995 the sports of Volleyball was hundred years old. In 1996 two person beach Volleyball was added to the Olympic. B. History of Volleyball in India: The Y.M.C.A. College of physical education in Madras (now Chennai) first began training its students in the sport, which then eventually spread to other parts of the country. Initially, the game was managed by Indian Olympic Association and the Interstate volleyball Championship was conducted every two years between the years 1936 and 1950. In the year 1951 the Volley Federation of India was establish. After India independence, the first Indian National Championship was organized in 1952 at Chennai. The Indian volleyball team won gold medal in 1955 at the International Asian Meet held at Japan. C. BMI & Growth: The Body Mass Index (BMI) is a heuristic proxy from human body fat based on individuals’ weight and height. BMI does not actually measure the percentage of body fat. It was devised between 1930 and 1950 by the Belgian Polymath Adolph Quetelet during the course of developing social physics. BMI is defined as the individual’s body mass divided the square of his or her height. The formula universally used in medicine produced unit measures of kg/m2. BMI= {Mass (in kg)/Height (in m)2 } Growth: Growth refers to an increase in sum quantity over time. The quantity can be: Physical (e.g. growth in height, growth in weight) Abstract (e.g. a system becoming more complex, an organism becoming more mature ) Growth, body composition influenced by complex interactions between genetic and environmental factors, which include nutrition, exercise and other aspect of lifestyle. Growth status changes with the change of age (male up to 25 and female up to 21). Puberty is a time of rapid change in size, shape and body composition for both sexes. Vo2 max: Vo2 max (also maximal oxygen consumption, maximal oxygen uptake, peak oxygen uptake or maximal aerobic capacity) is the maximum capacity of an individual’s body to transport and use oxygen during incremental exercise, which reflects the physical fitness of the individual. The name is derived from v- volume, o2- oxygen and max – maximum.

The litter expression is often used to compare the performance of endurance sport athletes. It depends upon some factors – i. Type of exercise, ii. Intensity of load iii. Duration iv. The person (age, sex, trained, un-trained, health etc.) e.g. at rest 200-300 ml/min (male), (Absolute unit) During Exercise Untrained Trained 3-3.5lit/min 4.5-5lit/min (Relative unit) Vo2 max = ml/min/kg At Rest-200/LBM (if 50kg) = 4ml/min/kg During Exercise Untrained Trained 40ml/min/kg 60-80ml/min/kg There is a close relationship between body composition (LBM) and oxygen consumption. The greater proportion LBM, the greater the maximal oxygen consumption both absolutely and kilogram body weight. D. Flexibility: Flexibility or limberness refers to the absolute range of motion in a joint or series of joint, and length in muscles that cross the joint. Flexibility is variable between individuals, particularly in terms of differences in muscle length of multi-joint muscles. There are two kinds of flexibility, static and dynamic flexibility. Static:-The range of motion about a joint is defining static flexibility. 1) Dynamic:- This type of flexibility is defined as the opposition or resistance of a joint to motion. The structural limits to flexibility are bone, muscle, ligaments, other structures associated with the joint capsule, tendons and other connective tissues and skin. Flexibility is improved by type of exercise and stretching. Along with strength and endurance, flexibility is also an important component of muscular performance. So Flexibility is very important of any type of activities. In volleyballs more required shoulder wrist, waist, flexibility and other flexibility of the joint. II. METHODOLOGY In this chapter procedures for collecting data and procedures for analysis have been discussed. This chapter deals with the subject, test, measurement, conducted; sample procedure tools used collection of data criterion measures method adopted for data collection. A. SUBJECT: The subjects of the present study were U-14 and U-19 district level male Volleyball players selected from Mushidabad, Basanta Sangha, Katwa Athletic Club and Tarun Sangha. Sixty two (62) male subjects were selected for this study. Among them, thirty one (31) male subjects for U-14 and thirty one (31) male subjects for U-19 years groups. 1) CRITERION MEASURES: To conduct the present study the following measurements were taken – a) Age b) Height c) Weight d) BMI e) Flexibility f) Vo2 max. 2) TOOLS AND EQUIPMENT USED: For measuring, Height, Weight, flexibility and Vo2 max. the following instruments and tools were used – a) Measuring tape (Stadiometer) b) Weighing Machine c) Flexometer d) Stopwatch e) Bench f) Metronome. 3) PROCEDURE OF DATA COLLECTION: The Age, Height, Weight, Flexibility and Vo2 max. of the subjects were measured in the following ways- a) Age: Age was recorded in completed year. The evidence regarding proof of age was gathered from Birth Certificate for the respective players. b) Height: The height was measured on a standard scale the reading of the scale taken in nearest centimeters. c) Weight: The weights of the subjects were recorded by the weighing machine. d) BMI: BMI (Body Mass Index) was measured by using this formula Weight (in kg) BMI= (Height in meter )2 e) Flexibility: Indirect method of flexibility was measured by sit and reach test. Hip and back flexion as well as extension of the hamstring muscles was measured through this test. The reliability of this were recorded from separate testing and correlated. A twelve (12inch) mark scale was used form a wooden box (Flexometer) and subject was directed to a long sitting position. Maximum reach by their fingertips were recorded as their flexibility. f) Vo2 max: Vo2 max was measured with the help of Queen’s College Step Test. The test consisted of stepping up and down on the bench (16.25’’ height) for 3 minutes. The cadence of 24 steps per min. is established by setting the metronome at 96 bpm. At the end of the time period the subjects remain sitting on the bench. Than we were counted pulse rate for a 15 sec. internal beginning 5sce.after the session of exercise. The score is total no. of pulse rate per minute. To measure the Vo2 max from this formula: Male = {111.33-(0.42 X pulse rate per min.)} ml/kg/min. III. RESULTS AND DISCUSSION The collected data were classified and presented in this chapter in the tabular form. The raw score were arranged according to design of the study. Appropriate statistical computation was made and computed score were presented in this chapter.
