Calculation results in Table 4, the value of F count is12.276. F count is higher than F table F count = 12.276 F = 4.149, it means that H is rejected and H 1 is accepted. Otherwise the second hypothesis that there is a difference between the effect of PNF flexibility exercises and static -passive to receive a service in takraw game is accepted . Based on the results of variant analysis, the conclusion says that there are significant differences between PNF flexibility exercises and static-passive to receive a service in takraw game. Furthermore q count = 4.955 compared with critical value of q table at significance level α = 0.05 with degrees of freedom df = 2.32, it’s obtained q table = 2.884. It shows that q count = 4.955 q tabel = 2.884. It means H is rejected and H 1 is accepted. The conclusion is PNF flexibility exercises are more effective than static- passive exercises 2. Different effect of high-speed reaction and low speed reaction to receive a service in takraw game μB1: μB2 Variant factorial analysis used to examine the hypothesis of different effect of high speed reaction and low speed rection to receive a service in takraw game with the significance level α = 0.05, critical value F table with degrees of freedom df 1 and 32 is 4.149. F count is 31.768. F count is higher than F table F count = 31.678 F table = 4.149. It means that H is rejected and H 1 is accepted. Otherwise it says that the third hypothesis, there is a difference between the effect of high speed reaction and low speed reaction to receive a service in takraw game. Based on the results of variant analysis, there are significant difference between athletes having high speed reaction and low speed reaction to receive a service in takraw game. q count = 7.971 and critical value q tabel with significant level α = 0.05 with degrees of freedom df = 2.32 is 2,884. The result shows q count = 7.971 q tabel = 2.884. It means that H is rejected and H 1 is accepted. Athlete having high speed reaction receive well a service than athlete having low speed reaction.

F count is higher than F table F count = 0.023 F table = 4,149. It means that H is accepted and H 1 is rejected. Hypothesis that there is an interaction effect between exercise flexibility and speed of response to receive a service in takraw game is rejected.

DISCUSSION The results of data analysis using ANOVA Analysis of Variants as statistical analysis needs to be explained: the acceptance or rejection of a hypothesis. The results can be interpreted as follows:

1. There is a different effect of PNF flexibility and static-passive to receive

a service in takraw game. PNF flexibility exercises are more effective than static-passive flexibility exercises. Stretching exercises of Proprioceptive Neuromuscular Facilitation PNF and static- passive, booth are static stretching, they are also an effective method of flexibility training to improve the skills to receive a service in takraw game. According to Santosa Giriwijoyo and Muchtamadji 2005:170, say that method static is stretching to expand the joint space, continuously as far as possible in accordance with ability, and then be hold for some time and is repeated several times. Training methods PNF Proprioceptive Neuromuscular Facilitation, who performed with isometric contraction and then be relaxed , would give a better effect of flexibility in the joints and muscles . It gives a good effect to extensibility the ability of the muscles to elongate when receiving a stimuli and resistance to stretching process . Joints and muscles will have better a sensitivity irritability to stimuli of motion, have a good ability to receive and respond to stimuli neuromuscular proprioceptive. PNF training method is more effective in improving flexibility of leg and body of takraw athletes compared to static - passive exercise. It is appropriate to results of research: PNF stretching utilizing a full relaxation . This relaxation is a protective mechanism to prevent tearing of muscle or detachement of tendon from the bone. It is possible to do further strain . Sudden relaxation induced by inhibitory effects can lead to muscle elongation more flexible than the method of static - passive exercises, which without any relaxation.
