    Will power or psychological competence, as well as physical fitness and skill, are essential in successful participation in athletic competitions. It seems, however, the exact definition on the concept of will power has not been given. In the present paper, an attempt was made to answer the question "What is will power?" Some aspects of will power as reflected in various behavior traits were examined by the factor analytic method. Then, the will power was considered from the ego psychological standpoint. Finally, the psychological mechanism of will power was explained by the following five ego functions: 1. Self-realization (A) (Achievement) 2. Ego defence 3. Energy integration 4. Ego resiliency, Ego flexibility 5. Self-realization (B) (Autonomy)

    The force-velocity relationships were determined on six adult males by two methods providing different previous states of shortening; the maximum elbow flexions were made against a gived load from (a) the state of isometric contraction (quick release method: QR) and from (b) the resting state (after load method: AL). The apparatus used was basically identical with one used by Wilkie (1950). The loads were prescribed by the fractiens (%) of isometric tension (P_o) of the individual. The velocity was measured using a linear velocity transducer. The results obtained were as follows; 1)The velocities under the loads above 10%P_o were unexceptionally greater in AL when compared them intra-individually. On the contrary the maximum velocities with no weight were greater in QR with the exception of two subjects. Thus, the force-velocity relationship in QR was more concave than that in AL; a/P_o values in the mean were 0.43 and 0.26 for AL and QR, respectively. 2)The maximum mechanical power in QR was about 25% less than that in AL. 3)The amount of action potentials during shortening, which was obtained by integrating the EMG of brachial biceps muscle with surface electrodes, did not show any considerable differences between QR and AL methods. 4)The initial accelerations, from the onset to peak velocity, were always greater in QR due to less time occupied to reach its peak velocity. 5)Taking these results and references into consideration, it was discussed that the greater velocity in AL might be in part due to an delayed recoil of elastic energy stored at an early stage of shortening, as in a whip.

    The effect of swimming training on cardio-pulmonary functions during tethered swimming and treadmill walking was studied crosssectionally in twenty-nine age group swimmers (8-21 years). All subjects underwent a progressive work test to the level of maximal volitional effort during treadmill walking and during tethered swimming. The results may be summarized as follows: 1. Maximal oxygen uptake (VO_2max, l/min) increased with age in both treadmill walking and tethered swimming. 2. No differences in VO_2max per unit of body weight (VO_2max, ml/kg/min) with age during either treadmill walking or tethered swimming were observed. 3. No differences in VO_2max between swimming and treadmill walking were observed at any age level. 4. No significant differences were observed between age groups until approximately 14 years. Beyond this age VO_2max was higher in all of the trained swimmers compared to the non-swimming groups.

    The purpose of this study is to analyze the effect of work factors on sport involvement. Samples of the study are 605 adult workers of both sexes working for three different companies. Main conclusions obtained through multiple regression analysis are as follows. 1. Main variables affecting sport participation are the experience of sport participation so far, watching and listening to sport programs on TV and radio, and joining sport clubs or teams. In terms of work factors, types of the job are the most influential on sport participation. 2. Variables which affect watching and listening to TV and radio sport programs are those of marriage, sport participation and sex. Among work factors, they are stability of occupation, types of the job, creativity in the job and working hours. 3. Sport satisfaction is significantly affected by such variables as age, the desire for sport participation and sport participation itself. As for work factors, they are types of the job, working hours, creativity in the job and job satisfaction. 4. Among work factors, main variables affecting sport involvement are types of the job, identification with the working situation and job satisfaction. Self-actualization in the job is also influential on sport involvement. 5. Meisner's "spillover pattern" is recognized between work and sport involvement.
