CONCLUSIONS
On the basis of the findings of the present study the followingconciusionswerc dmwn:. The age 35years to 40 years was the most risky age slot out ofthe
tbree age slots under study for prevalence of Blood Pressure and
Obesity related problems.. Obesity and gaining morc weight could be identified as one ofthe
impofiant components for increase in Blood Pressure. Therefore,necessary care must be taken by individuals to maintain weightand fat in order to maintain the nomal B lood Pressule.
. Healthy body composition is essential for optinizing health and
minimizing the risk of many of the most preyalent chroniccorlditions and diseases seen in owsocietytoday.
. Since obesiry is the deteminant of h),pertension, weight controlcouid be the most effective way to prevent hypefiension ilr a
population and to rcduce Blood Pressure among over-weight
hypefiensive subjects.

quickly under constantly chatrging corditions. The rule charged inVolleyball were minor until 1998 when the World Volleyball
Federation (FIVB) drastically changed the scoritrg in particular sets
and the qpes ofsubstitutions. The main objective oftle change was
to oreate the game more atbactive, especially to inqease the pace ofthe game. The standing serve, prgviously a passivo element, changed
into the spike serve ard became one ofthe more.powerful offensive
tools in volleyball. The psychomotor demands are constantly

In Volleyball, the libero is a specialist defensive player, which was
first introduced in the Indoor Volleyball in 1999. The sole purpose ofthis positionwas to fostell|ore digs andraliies, adding more thrill tothe game. A libero may replace any player in the back row. Thisreplacement is 11ot counted as a substitution. A liberc cannot seNe,
block or complete an attack hit from an).wherc if at the moment ofcontact the ball is above the net height. A tean mate may also notcomplete the attack hit on a bail coming from a libero.
Another impofiant player is Setter. The setter coordinates the
offensivc movements ofateam. He is thepiayerwho liits the ball up,
Ior lhe smasl'ler to smash, and uitimately decides which player wiliactually attack the ball, Setter decides who should get the ball and
when.It doesn't matter how good a team's hitters are ifit doesn't have
a setter that can't consistently deliver a good ball to hit. So we can say
thatwithout SetterinVolleyball 1eam, itlooklike headless horseman.The role of Libero and Setter are totally different, during playing
Volleyball. But the components which make them physically fit orenable them to become a elite performer inthe competition are quite
similar in respect of agility, explosive leg power, reaction time,strength, endurance, kinesthetic perception, odentation ability etc.
This has made the researcher to compare the explosive leg power and
agility betweer Libero and Setter
The Statement Of Problem
The purpose of the study was to detemine and compare the
Explosive Leg Power and agility between Libero and Setter ofstatelevel Volleyball players.
TheH)?othesis
On the basis ofavailable literature and scholar's own understanding

The Significance OfThe Study
i. The result ofthe study may enrich the literatu.e in rclation toExplosive Leg Power andAgilit)/ of Libero and Setter
ii. The Result ofthe study may help to the coaches to plan trainingschedlle for Libero & Setter in respect of Explosive LegPowerandAgility.
iii. The study may be helpful in flrture for screening ofthe aspiringplayen and selecting aplayerc.

DISCUSSION OFTHE FINDINGS
Finding of the present study showed that there was no significant
differences on Explosive Leg Power. Butin case ofAgility there was
found to be significant diffe|ence between Libero aDd setter ofstatelevel Volleyball playeN. AII the obtained values ofselected test items
i.e. -Explosive Leg Power andAgility were statistically analyzed. Itwas found that the calculaled "t"value on Explosive Leg Power
(0.2605) was not higher than required tabtlated "f'value (2.10) at
0.05 level of siguiflcanco. In case of Agility calculated "t"value
(2.3921) was higher than required tabulated "t" value (2.10) at 0.05
level ofsignificance.
Explosive leg powe. may be identified as the ability to release
n1aximum force in the fastest possible tine. This component helps
the Libero while defending the ball which has been driven by
opponent's Spiker. While defending the ball Libero generally uses
somedefensive skills likediving androiling (forward, backward, and
sideward) and changes the bodyposition towards the direction oftheball where Explosive leg Power play very vital rcle. SimilarlyExplosive LegPower helps the Setter whilejump and set the ball for a
good spike, which has been passed by back zone playels. Therefole
Volume - 13, lssue ' l, Jon. - June,20l3 (62) tssN 0976 - tl
INDIAN JOURNAT OF PHYSICAL EDUCATION, SPORTS MEDICINE & EXERCJSE SCIENCE
we can say that Explosive Leg Power has equal importance lbr bothLibelo a]ld Setter du ng playing situation and thus a non significantresult has been revealed.
Agiliq, may be defined as the physical ability which enables an
individual to rapidly change bodyposition and direction in aprecise
manner Agilif is apioneerfitness component for libero inVolleyballgame, generally Libero are smaller in size and they are more agile,
stable. Dudng games situation Libero can change his positionsimultaneously ftomposition 1 to 6 or 6 to 5 to dig the ball which has
been driven by opponent's spiker in one rally ofthe serve .Sometimes
he goes lor lift the dump or drop ball which may fall near to the Det infront zone .Therefore it is well accepted fact that Liberoplay around
dle entire cou1t.
Agiliq/ is also considered requisite for Setter in volleyball game
because they also change theirposition from 3 to 2 or 4 to 2 as well as
I to2,6 to2,5 to 2 according to theballpassing byback zone players.
But Agility is greater in Libero as compared to Settei because the
pace ofthe ball which has been driven by opponents spiker is more
than the pace ofball which has been passed by back zone players to
the Setter to set a ball for the spiker A significant rcsult as shown
signifies that Libero poses a better agility as compare to Setter.Research scholars also believed that above mention fitnesscomponents plays a vital role for both Libero and Setter duringvolleyball playing situation.
CONCLUSIONS
Onthebasis of resuit obtaiood from the study, following conclusions
weredrawn:i) Explosive Leg Power of libero and setter of state level

volleyball players is equal.
ii) The Agiliq/ oflibero is better than the agility ofsetter ofstatelevel volleybail players.
Recommendations
In the light of conclusion drawn, the following rccommendationsmaybemade:1 The same study can also be conducted on a latge number of
sampies.
Sinilar study inay be repeated on National and Internationallevel of volleyball players.
Same other studies can be undertaken in other disciplines(games and sports) also.
It is also recommended that a similarstudy maybe canied outby involving antbl:opometrical, physiological and sociologicalvadables.
The same study can also be conducted on female Volleyballplaye6.
On the basis of the result it may be reconmended that aseparate tratning programme be formulated for Libero andSetter.

INTRODUCTION
Volleybail has been played around the world for over one hundredy.-ars. It involves many pafticipants worldwide making it th€ mostpopular pafticipant spolt ir the world. The volleyball spike is one ofthe most important offensive weapons in the competition and themost fiequently used technique to obtain a point. The athlete isexpected to jump and hit a ball with maximum force and accuracy atthe approximate peak of the jump. Based on the variety ofmovements, the analysis of the volleybali spike is a complexapproach. The previous researchers (Coleman et al., 1993; Daviia etal. 1994) have investigated front spike techniques of ordinarypiaye$. Coleman et al. (1993) indicated that the volleyball jumpspike
-can be divided into the following six phuser, upprou"h; lluoi;
takeoffj flighl the hitting action; and landing and recovery Thepnmary objective ofthe spike is to di.ect the ball into the opponentscourt. Spike is an effective offensive weapon. Itprovide an eJlectiveattack because in this the ball can be hitwith a tremeldous amount offorce, whichreducesthe opposition's rcaction time aod consequently

Biomechanical analysis of the skills and role of player'sarthropometric characteristics involved in each phase enables us togive effective ioshlction and appropriate technical cries to improvetheperformaace ofvolleyballplayers. Still, we car state thatvery fewdetailed aathropometric studies have been canied 6ut.

Data Collection andAnalysis of Kinemaficvariables
The action ofthe front row spike for short and high set ball ofthe eight
spiker was recorded by a digital video camera (24fps). The camera
wasplaced on adgid tripod at a height ofl.30 metres from the ground
and at a distance of 10.50 metres from the sideline (Figure 1).
Following a briefwam up and shetchiug pe od, an assistant passed
the ball to the setter, who set the ball for each subject to peform live
front row spikes for high set ball. Only the best successful spiking
action was analyzed to measure tle selected kinematic parameters
with the help of motion analysis soltware (Power DVD). Afterprojecting a palticular frame the stickman configuation was drawn
from the frame. The time information was obtained fron the basic
fiequency of the camem and that was 24fps. Tbe jump height was
defined as the height from the vertical displacement ofCM at take offto the highestpoint. The ball velocity was denned as the velocity with
which the ball travels after impact (spike) \tith tie hand. Fig 2represeDts the Filming Environment for Collecting the Data fol this

Yoga has a great antiquity, long tadition and is a result ofthousand ofyears ofcareful and systematic explomtion by the long time ofsagesand Yogis on the basis ofthe meticulous observations and peisonalexpedences. Yoga is an art, ascience, a philosophy, a culture andto afew, religion all in unison. Any referonce to yoga must symbolize theintegrated whole and not any palt ofit. How this unification ofaftwith science, ofphilosophy with culture and ofboth these with theYoga way of life was achieved by Hatha Yoga deselves emphasis

BACKGROUND
It is thought that every cell in tho body expresses the vitamin Dreceptor, and therefore vitamin D may play a vital role in health and
homeostasis ofevery oryatl system (1).VitaminD is characterized as
a regulator of homeostasis of bone and 1nineral metabolism, but it can
also provide nonskeletal actions because vitamin D receptors havebeen found in various tissues including fhe brain, prostate, breast,
colon, parcreas, and immune cells. Bone metabolism, modulation ofthe immune response, and regulation of cell proliferation anddifferentiation are all biological functions ofvitaminD. Thercfore, ithas been proposed that vitamin D deficiency plays an impoftant rolein insulin resistance resulting in diabetos (2). The potential role ofvitamin D deficiency in insulin resistance has been proposed to be
associated with inhedted gene pol)noryhisms including vitamin D-binding protein, vitamin D receptor, and vitanin D I alpha-hydroxylase gene. Other roles have been proposed to involveimmunoregulatory function by adaptive immuniq/ and cytokinerelease, activating inflaDmation by regulatioD of nuclear factor (B

and inducing hrmour necrcsis factor o, and other molecular actions tomaintaitr glucose homeostasis and mediate insulin sensitivity by alow calcium status, obesitt or by elevating serum levels ofparathfoid honnone. These effects of vitamin D deficiency, eitheracting in concert or alone, all serve to increase insulil resistaDce.Although there is evidence to suppoft a relationship between vitamirD status aDd insulin resistance, the underlying mechanism requiresfurtherexplomtion(3).
Insulin rcsistance (IR) is a physiological condition where the insulinhomone becomes less effective or rcsistant at lowering blood suganwhich directly incrcase the blood glucose levels outside the romalraage and cause adverse health effects. In hsulin rcsistance, muscle,fat. and liver cells do nol respond properly to insulin and thus cannoteasily absorb glucose ftom the bloodsfteam. As a result, the bodyneeds higher levels ofinsulin to help glucose to enter ir the cells. Thebeta calls in the panqeas try to keep up with this hcreased demandfor insulin by producing more. As long as the beta cells are able toproduce enough insulin to overcome the insulin resistance, bloodglucose levels stay in the healthy range. Over time, insulin rcsistancecan lead to prediabetes stage because the beta cells fail to keep upwith the body's incrcased need for insulin. Without enough insulin!excess glucose builds up in the bloodstream, leading to prediabetes,diabetes ard other serious health disorders (3 O.
INSULIN RESISTANCE MECHANISM
There are several hl4rotheses. Each hypothesis is based on diferentpremises. Two importart mecha.nisms axe discussed in the followins.Resistin-mediated lnsulin Resistance, This idea was put for.lh byDr Mitchell Lazar, an endocrinologist at the University ofPennsylvania, in the j oumal Nature in Ja.nuary of Z0Ol .

his team discovered a hormone they callr'esistinwhichisproducedbythe fat cells that make up inta-abdominal fat (not the fat cells ofsubcutaneous fat). Like insulin, resistin is probably necessary for the
body's well-being in small amounts organisms usually have a
constmctive use for everything they make. But too much intra-abdominal fat means too much resistin. The excess rcsistin seems toprevent insulin from binding to cell membranes (the "skin" around
each cell). Itmay do this by aftachingto the same receptor molecules
onthe cell membrane that insulin is supposedto attach. Since the cellcan'tbind enough insulin to its nembrane, glucose can't enter the cellin sufficient anounts and the excluded glucose accumulates in the
blood. This causes blood sugar to start creeping up aod develop the
conditionthat doctors call "impaired glucose tolerance'" or- a more
populartermnow "prediabetes."
Another hypothesis is called Free fatty acid (FFA)-mediatedInsulin Resistance, and this one is under investigation in manyIaboratories right now. This hypothesis states that insulin rosistance is
the direct result oftoo many free fatty acids (FFAs) that have been
released into tho bioodstream by masses of excessive intra-abdominal fat. It appeaN that, in our muscles, FFAS interferc withinsulin metabolism by putling an extra phosphorous molecule on a
substance called insulin receptor substrate 1 (IRSl). When IRSI isphosphorylated it can't biDd insulin to a muscle cell's membrane and
the cell is then insulin rcsistant and it can't get enough glucose to
supply the energy it needs. High blood sugar leveis are due, for the
mostpaft, to the inability ofmuscle cells to take in giucose. We can
see that IRSI is very impotant. FFAS also go to the liver and, byinterfering with insulin metabolism there, cause that organ to spew
too much glucose into the blood, again raising biood glucose levels.
In thepancreas, FFAS causethe B-cells (the ones that secrcte insulin)

to over-secrete. So, all togethet, a person's blood sugar and insulinlevels will climb. In people who have type 2 diabetes, high serurnlevels ofFFAs seem to account for 50% of their insulin resistance.
The hormone rcsistin, also produced by intra-abdominal fat, mayaccount for much ofthc other half.

Is IRCurable by Supplementation ofVitamin D3?
Several studies support tlat vitamin D supplementation may affectglucose homeostasis or improve insulin resistance [12-14]Restomtion of vitamin D levels was shown to ameliomte glucosetolerance in a study on one hypocalcemic woman with vitamin Ddeficiency [15]. Asignificant increase in serum calcium levels and areduction in semm free fatlr acid levels have been found after takilgvitamin D supplementations 1161. Recently, a New Zealand studyfound that south Asian women with insulin fesistance improved

markedly after taking vitamin D supplements [17]. The optimalvitamin D concentrations fol reducing insulin resistance ltave beenshown to be 80 to 1l9nmol,rl, providing furlher evidence for anincroase in the recommended adequate levels [18]. In view of theabove studies we in this review study try to investigato the effect ofvitaminD on insulinresistance in different health disordeN.
METHODS
The researcher conducted a thorough online search on the publishedmate als. The online search was rest cted to original research workavailable on Pubmed, Google, Jstorc, Science daily, science dircctetc. The schola.r identified very fe1/ studies which directly focus onrole ofvitamin D on insulinresistance in differenthealth disorders.
FINDINGS
rype2 Diabetes(T2DM)
Studies showed significatt imp.ovements in serum FPG, insulin andin HOMA-IR after heahnent with vitamin D, suggested that vitaminD supplementation could reduce insulin rcsistance in T2DM.Different studies provide evidence that vitamin D may play a
f,rnctional role iD glucose tolerance tbrough its effects on insulinsecretion and insulin sensitivity. Effects of vitamin Dsupplementation on glucose homeostasis have been shown innumerous studies. Findings ofthis study ar.e consistent with rcsults ofmany olherpublished studies, in which the insulin rosistance appeanto be decreased in T2DM patients who had received vitamin D12,4 ,5 ,12,13 ,14,r6,r81.

Overweight and Obese
Insufficient vitamin D status has been linked to autoimmrme diseases,canper and metabolic disorders, like obesity and insulin resistance.Vitamin D may reduce adiposify, thereby improving insulinsensitivity indiectly though improving muscle mass and thereduction in vitamiq D status with increased a diposity [.7 , 31 , 32,33 ,14.35.t61.
Peritotreal Dialysis patients
One study aimed to explore the effects of cholecalciferolsupplementation on vitamin D levels, insulin rcsistarice, lepfln, andadiponectin levels in vitamin D-defcient,peritoneal dialysis (pD)patients. Cholecalcifercl rcplacement therapy signifi cantly iecreasesPTH levels and insulin resistance [g, 1 0, 1 l, 22].
The effect of different doses of vitamin D supplementation oninsulinresistance duringpregnancy
Low 5srum vjtamin D levels are corelated wjth insulin resistatceduring pregnancy. Study has shown that supplementation ofpregnantwomen with 50000ru vitamin D every 2 weeks improved insulinresistance signifi caDtly [3].
Vitamin D,Insulin Resistance, and CardiovascularDisease
In recenr years. vitamin D bas been sho\)v,n nor oDly to be importaDtfor bone and calcium metabolism but also forhomeostasis ofcrilicalhssues involved in vascular disease in patients with diabetes.Epidemiological shrdies indicated the high prevalence of vitamin Ddeflciency among T)?e 2 DM patients and suggest an increased dsk ofcardiovasculardisease [9;1 l].

DISCUSSION
The main purpose of this study was to investigate the effects ofvitamin D on insulin resistance in different cardiometabolic ailments:
The rcsults showed that vitamin D supplementation significattlydecreasedserumFPG;insulinandHOMA-IRinpatientswithT2DM.A rcduction in adiposify in obesity and decrease IR in peritoneal
dialysis patients ard so on took place. Protective effects ofvitamin Don diabetes may be due to well known effects ofvitamin D such as its
anti-inianrmatory prcperties, its effects on calcium and phosphorus
metabolism and regulation of the insulin receptor gene. Vitamin Ddeficiency is associated with increase in inflammation. Vitamin Dattenuates the expression ofproliniammatory q'tokines involved ininsulin resistance. It would be useful, though to undertake firtherstudi€s to discover more about the mechanism and the eff€ct ofvitamin D on both alpha and islet beta-cell fiutction and also on the
mecbanisms delermining insulir resisrance.
CONCLUSION
Vilamin D is no{ only a regulator ofbone and mineral metabolism. but
also a potent immrmomodulatoi linked to many major human diseases
including glucose homeostasis and insulh resistance. Vitamin Ddeficiency has be€n shown to affect insulin secretiotl in humans and
supplementations of vitamin.D may provide a suitable management
and act to ameliorate insulin resistance.
