Results of the study have shown that, in case of evaluating expression of athletes’ motives in the fivepoint scale, intrinsic motivation is more expressed than the extrinsic in both, the first and the second, groups and the group of motives related to striving for experience adherent to inner motivation is the most expressed one (RN-3.91±0.58, SM-4.01±0.62). It was found that less advanced athletes respond to direct external control (p<0.05) and higher expression levels of intrinsic motivation to know (p<0.05) is more pertinent to them rather than to members of the National Team. Meanwhile, members of the Lithuanian National Team have better expressed amotivation (p<0.05) compared to the athletes of other group. It could be partly explained by the fact that National Team members are setting themselves more ambitious and heavily achievable goals, which are more difficult to achieve. In case of failure achieving them, National Team members begin to question about their abilities and competence and even about meaningfulness of further sport activities. Having evaluated expression of motives for doing sports in girls and boys it was found that boys feel stronger need for extrinsic motives (p<0.001). On the other hand, higher level of amotivation is more typical for girls, than boys.

Object of research was motivation of the Lithuanian army soldiers and the influence of physical training instructors on the soldiers’ motivation. Aim of research is to reveal the motivation of the Lithuanian army soldiers regarding physical training exercise and the influence of physical training instructors on motivation. Methodology of research. 242 soldiers of Lithuanian Armed Forces were interviewed by questionnaires in total. 30% of which are compulsory primary military service soldiers. The age of the soldiers in the research ranges from 18 to 54 years and the length of service varies between 1 and 30 years. In order to achieve aim and goals of research 3 scales as anonymous questionnaires were used: Situational motivation scale; The Amotivation Inventory-Physical education scale and Interpersonal behaviour scale. The participants of the research had to evaluate every statement of scales using a 5-point Likert scale, ranging from ‘strongly disagree’ to ‘strongly agree’. The analysis of research data has been carried out using SPSS 21.0. Reliability and inner coherence of the sub-scales have been found grounding on the following: Cronbach α coefficient; correlations of the statement with the subscale by the Item-total Correlation coefficient and Cronbach α c, efficient having eliminated the statement. Conclusions. Analysis of the causal relationships between the Situational Motivation Scale subscales and the Amotivation Inventory-Physical Education showed that soldiers are more likely to be motivated by both intrinsic and extrinsic motivation. It has been revealed that soldiers are most involved in physical training with identified regulation of external motivation. The statements describing intrinsic motivation are also highly valued.[...]
