Introduction
University students subjective well-being and personality attitude have great differences, such as different genders, different students origins and different disciplines, they have great differences, but how to eliminate such differences and make contributions to healthy university students personality building are of people general concerns.Someone guesses that applies physical exercises method to improve university students' subjective well-being and personality attitude, the paper takes this as base point, explores the three relations, in the hope of making contributions to university students healthy growth [1][2][3].
The paper on the basis of former researches, explores university student subjective well-being and personality attitude as well as physical exercises relations, with an aim to provide theoretical basis for physical exercise being capable of improving university students subjective well-being and personality attitude.

Overview of physical exercises, well-being and personality attitude
Physical exercises can make classification according to ways as following: 1) Classify according to exercises participants, in this way, it can divide into collective exercises and individual exercises.
2) Classify according to exercises process human physiological metabolism features, in this way, it can divide into aerobics, anaerobics and combinative aerobics and anaerobics such three kinds.
3) Classify according to physical exercises events feedback features, in this way, it can divide into open technology and closed technology two kinds, the later needs to make feedback adjustment relying on internal and ontic sense organs.4) Classify according to physical exercises competitiveness, in this way, it can divide into entertainment sports and competitive sports, the former exercise purpose is build body and for pleasure, the later exercise purpose is to pursuit highest, furthest and strongest.
Physical exercises have a variety of kinds, sportsman should make exercise standardization according to one's own different demands, evaluate physical exercises standard variables normally use exercise intensity, exercise frequency, exercise duration and sports population the four to make comprehensive analysis, in the following, it overviews above four variables, in the hope of providing scientific evaluation carrier for physical exercises behaviors well-being differences and personality attitude differences under different dimensions [4].
1) Exercise intensity: The variable often uses heart rate, pulse or blood pressure such kinds of physiological indicators to make evaluation, in order to make classification of exercise intensity, the paper thinks that when breath and heartbeat little change and its highest heart rate is around 60%, it is the small intensity, while breath and heartbeat get faster and highest heart rate is between 65%~70%, it is medium intensity, and breath and heartbeat changes very fast and sweat more as well as heart rate arrives at 80%~90%, it is high intensity.
2) Exercise frequency: The variable often uses exercise durations per week to measure.
3) Exercise duration: The variable often uses physical exercise schedule rationality and exercise duration per time to measure.
4) Sports population: Measurement of the variable is a number, judgment of sports population can carry on accord physical activities arrive at above three times per week, physical activities time is above 30minutes per time and physical activities intensity arrives at medium and strong intensity criterion, when people simultaneously meet above three conditions, he is supposed to a member in sports population.Personality attitude uses people positive and optimistic mental states to present, and optimism is a kind of important positive experience, is a kind of explanation style not general personality features.Many researches how two factors model has better distinguish effects on physical health status and emotion status prediction, effects merits have been verified by structural equation model by someone.

Research objects
The paper selected research objects are from one province four universities sophomore students, total sample size is 440; it makes investigation on research objects daily physical exercise, well-being and personality attitude.
Research objects can use gender, students origin, single child or not and located major and discipline type to make classification, according to above classification, students amount basic information is as Table 1 shows.
Research objects each sports event number of people basic status and different exercises ways status are as Table 2 shows.

Research methods
In the paper, it adopts document literature, questionnaire survey and mathematical statistics.
1) Documents literature The paper searches from China national knowledge internet 10 pieces of periodical literatures about university students physical exercises researches, 12 pieces of periodical literatures about university students physical exercises and well-being correlation researches, and 8 pieces of periodical literatures about university students physical exercises and personality attitude correlation researches, which provides theoretical basis and research orientations for the paper researching.
2) Questionnaire survey The paper adopts "physical exercises questionnaire" to investigate on research objects exercises purposes, exercise events, exercises participation constraint main factors, exercises history, exercises ways at ordinary times, exercise intensity, exercise frequency and exercise duration eight aspects contents.
Apply "General well-being schedule" to make investigate on research objects health concerns, vigor, satisfaction and interests on life, melancholy or pleasure mood, controlling of emotion and behaviors as well as relaxed and tight theses six aspects.Apply "Dispositional optimism questionnaire" to score on research objects with optimism and pessimism two dimensions, in the hope of scoring on research objects personality attitude.
In the hope of exploring positive effects that physical exercises bring to university students well-being index and physical exercises provided positive promotions to university students' personality by above three questionnaires data processing results and statistical test results.
The research released questionnaires are totally 500 pieces, its returning rate arrives at 100%, from which physical exercises questionnaire an subjective well-being invalid questionnaires amount are totally 19 pieces, dispositional optimism questionnaire has 4 pieces of invalid questionnaires, and still 37 pieces of questionnaires unfulfilled are regarded as invalid questionnaires, so, questionnaire survey effective returning rate is 88% this time.
3) Mathematical statistics In order to do data processing with effective return questionnaires, it adopts mathematical statistics method, data statistical amount calculation is fulfilled by statistical software SPSS, carries out independent sample T test, correlation analysis and single factor variance analysis of sample data group.

Empirical analysis
University students physical exercises participation frequency, exercise duration per time and exercise intensity investigation result is as Table 3 shows, research objects total sample size is 440 people, it appears in the form of percentage in the table that number of people percentage in total samples under the type [5].
By Table 3 5 shows, add a "*" behind test value represents corresponding P value is less than 0.05, add two "*" represents corresponding P value is less than 0.01, add three "*" represents corresponding P value is less than 0.001.
By Table 5 data, it is clear, in subjective well-being six factors, except for satisfaction and interests on life factor and health concerns factor, other four factors are in positive correlation with exercise intensity, exercise duration and exercise frequency, satisfaction and interests on life factor is in negative correlation with exercise frequency, while health concerns factor is in negative correlation with exercise intensity, exercise duration and exercise frequency; among them, exercise intensity and health concerns have significant differences, exercise frequency and vigor have significant differences, exercise duration and controlling of emotion and behaviors factor has significant differences.In Table 5, it also reflects that optimistic factor is in positive correlation with exercise intensity, exercise duration and exercise frequency, while pessimistic factor is in positive correlation with exercise duration and exercise frequency but in negative correlation with exercise intensity, personality attitude two factors have insignificant differences in exercise intensity, exercise duration and exercise frequency [6].

Conclusions
University student exercise duration below half an hour occupy 36.59% of totals, and university students that arrive at above 30 minutes exercise duration occupy 63.41% of totals, in the view of exercise duration, nearly 70 percent students can arrive at exercises effects.Under little intensity exercises, university students occupy 30.22% of totals, the part students exercise intensity is to be improved, students take moderate intensity and enduring exercises are 24.77%,students take heavy intensity and non-enduring exercises are 31.14%,only 7.05% students can insist on heavy intensity and enduring exercises, which shows most of students love moderate intensity exercises and heavy intensity but non-enduring exercises, it doesn't advocate heavy intensity and enduring exercises here.Schoolgirls that take exercises below third times per month occupy 20% of totals, the figure is relative pessimistic, it needs such part schoolgirls to improve their exercise frequency, exercise times arrive at above third times per week can be called as sports population, the part students occupy 34.77% of totals, from which schoolboys occupy 20.68%, schoolgirls occupy 14.09%, the figure is also not optimistic, which needs to be improved especially for schoolgirls.
