“…Compared with badminton players, archers and nonathletes, swimmers exchibit better muscle symmetry and increased symmetry of autonomic indices (Balashova et al, 2004). In addition, adolescent swimmers have more stable circulatory system than those, who are not engaged in sports (Luchitskaya and Rusanov, 2009), and they have lower heart rate at rest than basketball players and other athletes (Vanyushin and Sitdikov, 2001). …”

While there is a direct relationship between maximal anaerobic power (Pmax) and swimming performance, the relationship between upper and lower limbs with regard to Pmax and force-velocity (F-v) characteristics is not clear. The aim of the present study was to examine the effect of age and sex on the ratios of mechanical characteristics between upper and lower extremities of adolescent swimmers. Seventeen girls (aged 14.7±1.8 yr) (mean±standard deviation) and 28 boys (14.6±1.4 yr), all members of competitive swimming clubs, performed a F-v test for both legs and arms. In legs, boys had higher values of Pmax (t43=2.4, p<0.05), Pmax expressed in relative to body mass values (rPmax, t43=3.4, p<0.01) and v0 (t43=4.3, p<0.001), while no differences were found for F0 (t43=1.0, p=0.31) and v0/F0 (t43=0.55, p=0.59). In arms, boys had higher values of Pmax (t43=3.2, p<0.01), rPmax (t43=3.9, p<0.001) and v0 (t43=3.4, p<0.01), while no differences were found for F0 (t43=1.9, p=0.06) and v0/F0 (t43=0.16, p=0.87). However, no sex difference was found with regard to the ratios of Pmax (t43=1.9, p=0.06), F0 (t43=1.2, p=0.23) and v0 (t43=1.3, p=0.20) between upper and lower extremities. There was direct relationship between age and Pmax of legs (r=0.64, p<0.01 in girls; r=0.43, p<0.05 in boys) and arms (r=0.56, p<0.05; r=0.57, p<0.01 respectively), while there was not any significant association between age and the ratios of mechanical characteristics of upper and lower limbs. These findings emphasize the need for separate evaluation of arms’ and legs’ force-velocity characteristics on a regular basis and the consideration of these measures in training design.

“…Motor activity cannot be conceived without the effort that it is based on. In this sense, one could speak of a functional motor system that conducts itself efficiently, adapted to the demands of the internal and external environment (Luchitskaya & Rusanov, 2009). Holmer and Astrand (1970) showed that the strength-speed tests and the measurements of the maximal oxygen intake performed in the laboratory on the upper limbs are the closest to the act of swimming, because it involves the most representative type of muscles used.…”

“…Activitatea motrică nu poate fi concepută fără efortul care stă la baza acesteia. În acest sens, se poate vorbi de un sistem motric-funcţional, care realizează o conduită eficientă, adaptată solicitărilor mediului intern şi extern (Luchitskaya & Rusanov, 2009). Holmer şi Astrand (1970) arată că testele de forță-viteză şi încercările de măsurare a consumului maximal de oxigen efectuate în laborator, cu membrele superioare, sunt cele mai apropiate de activitatea de înot, deoarece implică tipul cel mai reprezentativ de muşchi de tip practic.…”

It would be recommended to pay swimming the proper attention, both from the perspective of knowing the effort involved and its training methodology. New studies have shown that there are other ways of getting results, sometimes in a shorter period of time than in the case of classic training. A new method, used in this study, is repeat sprint training. The difference between the sprinters' technique and the long distance swimmers' technique is mainly in regard to the race rhythm, more than the specialization of the swimmer. The hypothesis of this research is that repeat sprint training influences/ improves the swimmers' aerobic capacity. At the end, an increase was observed in the maximum alactic and lactic powers, of 50% and 83%, respectively, after the training, in all experimental group subjects.
