    The research tried to discover/find out [1] whether the success of transformation of max muscle power will be just because of the training sessions? Or perhaps [2] the genetic potential of examinees will be important to make bigger and faster transformation of max muscular power. The experimental program was applied within (N) 21 examinees, age of 18-20 years, non-athlete population, for a period of 6 weeks. The programme included exercises for transformation of the maximal strength component of the flexors and extensors muscles on the elbow of the examinees' non-dominant arm (load- 90-95% of one repetition maximum). Three tests for one repetition maximum (flexion+ extension) were performed (program start, 3th and 6th week). Mutation of ACTN3 genotype allele, of the examinees, were analysed, according to establish three types of examinees: (type I) slow-oxidative - XX type/group, (type IIA) fast oxidative/glycolytic RX type/group and (type IIB) fast glycolytic -RR type/group. The three groups of examinees (XX, RR, XR) do not differ in terms of the achievements of one repetition maximum (flexors/extensors) after 3th and after 6th week. The genetic predisposition of the muscle tissue for strength capacities is not always decisive for the transformation of the maximal strength abilities.

    The ability for maximum strength is separated as a sub-component of the strength abilities. This maximal area in the general image of the strength capacities is recognized through highly intensive loads with short duration of 2 to 3 seconds or 1 to 3 repetitions. The method for maximal strength transformation takes into account the following components: external load (90-95% of 1RM), number of repetitions in one series (1-3 repetitions), number of training series (from 3 to 4 series), break of 1.5 to 3 minutes between series, next training 24-48 hours after training depending on the category of footballers. Significant improvement of the maximal strength can be observed after 3 weeks of the training program. Regarding the maximal strength transformation, since the execution of movements is high in terms of intensity, 1 to 3 maximal load repetitions, it is safer for the movements to be isolated in muscle groups (chest-only exercises, only back exercises, kick, etc.). However, other exercises should also be performed, such as: deadlift, throwing, pulling, pushing, with maximal intensity with duration of no longer than 2-3 seconds, should not be performed. In this manner, the entire body is involved (functional training), but with the dominant method being the maximal power transformation.
