According to the rules of FINA, world records in butterfly are recorded on the 100 and 200 meters for men and women. In addition, the butterfly is represented in the individual medley on the 200 and 400 meters, as well as the combined relay 4 x 100 meters (third phase).

Michael Phelps's butterfly swimming technique I would like to point out that Michael Phelps's lays quit high on the water. His technique differs from others by the quit flat position of the body and by making the stroke maximal path of movements. His technique minimizes frontal resistance. As we can see, Michael Phelps's butterfly swimming technique is better than others' athletes techniques. This success is reached not only with Michael Phelps's strong physical abilities (big high and long hands) but also with the good special training. The science says that a long powerful stroke in swimming depends on the effectiveness of the technique and special force of the swimmer Social aspects of the biography Michael Phelps was born on June 30, 1985 in Baltimore (USA). His mother Debbie is a school teacher and his father Fred is a soldier. Michael Phelps was the third child in the family. Two older sisters were swimmers too. One of them was a member of The US Team at the World Championships in 1994 in Rome. He began to swim at the age of seven. His coach is Bob Bowman.

Michael Phelps refused to study at the university. In United States athletes-students are required to participate in all students competitions that take place every week. Michael together with his coach found sponsors who agreed to pay for his education. So, he was able to work quietly, without boosting training.

The aims of the present research
1. Analyze the layout time by 50 meters in the 200 meters butterfly in the final
swim at the Olympic Games
2. Formalize the layout of the time intervals for distance in a generalized formula

Method and Structure of the research
1. Work with literature and other information sources.
2. Analyze of sports documentation (protocols, the 2008 Olympic Games).
3. Methods of mathematical statistics.
4. Analyze video materials.

Individual layout time (s) finalists in the 200 meters butterfly on the Olympic Games 2008.
At this table we see the layout-time finalists in the 200-meter butterfly on the Olympic Games 2008. Michael Phelps swam on the 4th lane. He beat his nearest competitor Laszlo Cech by zero point sixty-seven hundredths of a second. Following results came from this table.

Findings
These Data was obtained from these formulas
Formulas
x = Σ t ’ n (all participants)
δ = √ δ2 = √ Σ (xi – x) 2 ’ n - 1
t, % = x ’ t ср * 100 %

Results
We conclude that the average time layouts (%) on the 50 meters intervals can be used to calculate the travel time-distance in accordance with the planned result.
To do this, result (for example it can be 120 s) should be multiplied by the relative time (%) and divided by 100.

For convenience, instead of the relative time (%) a factor (коэффициент) саn be introduced:
For example
1 st 50m: 120 × 0,225 = 27,0
2 nd 50m: 120 × 0,253 = 30,36
3rd 50m: 120 × 0,258 = 30,96
4 th 50m: 120 × 0,262 = 31,44

Conclusions
We obtained average layouts time (%) on the 50 meters distance intervals. These layouts can be used to calculate the probable layout to overcome the 200 meters butterfly in accordance with the planned result We have derived a formula for calculating the layout of the time in the 200 meters butterfly, which can be regarded as a basic formula to calculate the "specific strength" in parts of the 200-meter butterfly.
