This research was intended to study the physical fitness body mass index and normal norms of the physical fitness of volleyball athletes in Rajamangala University of Technology Phra Nakhon academic year 2016. The population was 15 male and 15 female RMUTP volleyball players. The instruments employed in the research were the Physical Fitness Test of the Department of Physical Education which included front bending standing and jumping sitting-up for 30 seconds running and picking up objects for 50 meters and Harvard Step Test. The Statistics used for analyzing the data were percentage mean (xˉ) standard deviation (SD) and t-score. The research findings were as follows: 1. Age weight height and body mass index (BMI) of female volleyball players: the average age is 20 years the average weight is 56.87 kg the average height is 165.60 centimeters the average body mass index is 20.67 and the overall average physical fitness of female volleyball players was moderate. 2. Age weight height and body mass index (BMI) of male volleyball players: the average age is 22 years the average weight is 79.87 kg the average height is 180.53 centimeters the average BMI is 24.31 and the overall average physical fitness level of male volleyball players was moderate. 3. Normal norms of the physical fitness level of female volleyball players were as follows: 3.1 Front bending: very high level matches with the T-score above 61 high level at 55 - 60 moderate level at 45 - 54 low level at 40 - 44 and very low level below 39. 3.2 Standing and jumping: very high level matches with the T-score above 61 high level at 55 - 60 moderate level at 50 - 54 low level at 45 - 49 and very low level below 44. 3.3 Sitting-up for 30 seconds: very high level matches with the T-score above 60 high level at 55 - 59 moderate level at 45 - 54 low level at 40 - 44 and very low level below 39. 3.4 Running and Picking up objects: very high level matches with the T-score above 61 high level at 55 - 60 moderate level at 45 - 54 low level at 40 - 44 and very low level below 39. 3.5 Running for 50 meters: very high level matches with the T-score above 60 high level at 55 - 59 moderate level at 45 - 54 low level at 40 - 44 and very low level below 39. 3.6 Harvard Step Test: the Physical Fitness Level of female volleyball players was high level. Twelve players (80.00%) had the index of the physical fitness at high above 80; the other 3 players (20.00%) were at a moderate level that is the index of physical fitness was 50 - 80. 4. Normal norms of the physical fitness level of male volleyball players were as follows: 4.1 Front bending: very high level matches with the T-score above 61 high level at 55 - 60 moderate level at 45 - 54 low level at 40 - 44 and very low level below 39. 4.2 Standing and jumping: very high level matches with the T-score above 61 high level at 55 - 60 moderate level at 50 - 54 low level at 45 - 49 and very low level below 44. 4.3 Sitting-up for 30 seconds: very high level matches with the T-score above 60 high level at 55 - 59 moderate level at 45–54 low level at 40–44 and very low level below 39. 4.4 Running and Picking up objects: very high level matches with the T-score above 61 high level at 55 - 60 moderate level at 45 - 54 low level at 40 - 44 and very low level below 39. 4.5 Running for 50 meters: very high level matches with the T-score above 60 high level at 55 - 59 moderate level at 45 - 54 low level at 40 - 44 and very low level below 39. 4.6 Harvard Step Test: the Physical Fitness Level of male volleyball players was in moderate level. Ten players (66.67%) had the index of the physical fitness at 50-80; the other 5 players (33.33%) were at a very low level that is the index of physical fitness was below 50.

The purposes of this research were to 1. Study the effects of ballroom and Latin American dance training on physical fitness 2. Compare the effects of ballroom dancing and Latin American dance training on physical fitness. The samples were 30 undergraduate students of Rajamangala University of Technology Phra Nakhon 15 male students and 15 female students. They were equally divided into 3 groups of 10 students. Each group consisted of 5 male and 5 female students. Group 1 was the control group; group 2 performed ballroom dancing and group 3 performed Latin group dance. The experiment took 8 weeks 3 days a week one hour each time. The physical fitness tests were tested before week 4 and week 8 and the obtained data were statistically analyzed in terms of means standard deviation one-way analysis of variance analysis of one-way covariance with repeated measurements. The research results were as follows: 1. After the 8 weeks of the experiment it was found that the dance practice of the ballroom dancing group and Latin American dance practice group made the average of 1 minute lifting 1 minute ground pushing and 3 minutes step-up. It was significantly better than the control group at the .05 level. 2. As for the ballroom dancing practice within the ballroom dancing group it was found that after the 8 weeks of the experiment the average of 1 minute floor push and 3 minutes step up and down. It was significantly better than before the experiment and 4 weeks after the experiment at the .05 level 3. The results of Latin American dance training showed that after 8 weeks of experiment the mean of 1 minute lifting and 3 minutes of step-up and down was significantly better than before the experiment and after 4 weeks of experiment at the .05 level.
