| Popis: | Cilj istraživanja je usporedba učinaka dinamičkog istezanja i proprioceptivne neuromuskularne facilitacije (PNF) na izokinetičke parametre jakosti i snage koljenog zgloba. Uzorak čini 50 sportaša muškog spola podijeljenih na poduzorke od 10 ispitanika takmičarske razine karate (19 ± 2,4), tekvando (20 ± 3,6), boksanje (19,8 ± 4,3), nogomet (15,1 ± 0,3) i atletski sprint (18,3 ± 2,6). Izokinetički parametri koljena su mjereni Biodex izokinetičkim sustavom 3, na dvije kutne brzine 60 °/s i 180 °/s. Parametri su mjereni nakon dinamičkog istezanja te 48 sati kasnije nakon PNF protokola. Kod karatista i tekvando boraca nisu utvrđene značajne statistički razlike. Kod boksača, nogometaša i sprintera parametri jakosti i snage su veći nakon protokola dinamičkog istezanja. Rezultati ovog istraživanja potvrđuju da dinamičko istezanje doprinosi ispoljavanju većih vrijednosti izokinetičkih parametara jakosti i snage. Purpose of the research was to compare the effects of dynamic and proprioceptive neuromuscular facilitation (PNF) stretching on knee isokinetic strength and power parameters. Sample size of 50 male athletes is represented as male athletes divided into sub-samples of 10 athletes at competitive level in karate (19 ± 2,4), taekwondo (20 ± 3,6), boxing (19,8 ± 4,3), football (15,1 ± 0,3) and track and field sprint (18,3 ± 2,6). Isokinetic parameters of the knee were measured using Biodex isokinetic system3, at two angular speeds 60 °/s and 180 °/s. Parameters were measured after dynamic stretching protocol and again 48 h later after PNF protocol. For karate and taekwondo fighters no statistically significant differences were found. For boxers, football players and sprinters the values of strength and power parameters were higher after dynamic warm-up protocol at a statistically significant level. Results of this study confirmed that dynamic stretching contributes to higher values of the strength and power of thigh muscles compared to proprioceptive neuromuscular facilitation. |
