Abstract. Whole body vibration training (WBVT) as a new method of neuromuscular training has been considered and it has been vastly studied as a factor for strong mechanical stimulation in the neural system, bone tissue and muscles. The aim of this study was to investigate the effects of whole body vibration training on the explosive power and speed of male non-athlete students. For this purpose twenty students from the University of Kurdistan (Mean; age: 21/5 ± 1/4 yr, Weight: 71/5 ± 5/5 kg, Height: 174 ± 5/5 cm, BMI: 23/67 ± 1/30) were recruited and randomly divided into an experimental (EG) (n=10) and a control group (CG) (n=10). The EG were treated for four weeks, three session per week with 5 sets of 1 minute in a squat of 110◦ body position, for a total of five minutes per day. The subjects of the CG were asked to maintain their normal activity and avoid strength training. The subjects were tested at the beginning and the end of treatment with a specific functional test. The data were analyzed using SPSS and the Paired-t test statistical method. The results showed a remarkable and statistically significant enhancement in the EG with a 7.8% increase in explosive power (P≤0/002), and there was a significant difference in EG speed (5m: P≤ 0.001, 10m: P≤0.042 and 20m: P≤0.001) at the post-test. But no significant difference was found in the CG for this performance (P≥0.05, P≥0.05). Overall, we can conclude that whole body vibration probably can have an effect on explosive power and speed. Hence, WBVT can be used as a new method of training for athletes.

UTICAJ TRENINGA VIBRACIJAMA PO CELOM TELU NA RAZVOJ EKSPLOZIVNE SNAGE I BRZINE KOD NESPORTISTA MUŠKOG POLA
Vibracije koje zahvataju celo telo (WBVT) su dosad proučavane kao metod neuromuskulatornog treninga, a dosta su istraživane kao faktor za jaku mehaničku stimulaciju nervnog sistema, kostiju i mišićnog tkiva. Cilj ovog istraživanja je da prouči uticaj treninga vibracijama koje zahvataju celo telo na eksplozivnu snagu i brzinu kod nesportista muškog pola. U istraživanju je učestvovalo 20 studenata sa Univerziteta u Kurdistanu (Srednja vrednost; starost: 21/5 ± 1/4 yr, težina: 71/5 ± 5/5 kg, visina: 174 ± 5/5 cm, BMI: 23/67 ± 1/30) koji su metodom slučajnog izbora podeljeni na eksperimentalnu (EG) (n=10) i kontrolnu grupu (CG) (n=10). EG bila je podvrgnuta ovakvom treningu u trajanju od četiri nedelje, sa po 3 treninga nedeljno od 5 seta u trajanju od 1 minuta u čučnju od 110◦, ukupno po 5 minuta u toku dana. Od CG se tražilo da ne menjaju svoje svakodnevne aktivnosti i da izbegavaju vežbe snage. Učesnici su mereni na početku i kraju tretmana uz pomoć posebnog testa. Podatke smo analizirali uz pomoć SPSS programa i t testa za zavisne uzorke. Rezultati su pokazali statistički značajno uvećanje kod EG sa povećanjem od 7.8% u eksplozivnoj snazi (P≤0/002), a javila se i značajna razlika u brzini EG (5m: P≤ 0.001, 10m: P≤0.042 i 20m: P≤0.001) u post testu. Ali statistički značajne razlike kod CG u ovom slučaju nije bilo (P≥0.05, P≥0.05). Na kraju, možemo zaključiti da vibracijama koje zahvataju čitavo telo verovatno možemo uticati na eksplozivnu snagu i brzinu. Zbog toga, WBVT se može koristiti kao novi metod za trening sportista.
