Effects of six weeks of depth jump vs. countermovement jump training on sand on muscle soreness and performance/Ucinci sest tjedana treninga dubinskih skokova i skokova s pripremom na pijesku na misicni zamor i izvedbu

The purpose of this study was to examine the effects of six weeks of depth jump (DJ) vs. countermovement jump (CMJ) training on sand on muscle soreness, jump, sprint, agility and leg press strength. Thirty healthy men (age 20.4±1.1 years; height 177.4±5.1 cm; mass 72.8±9.7 kg) volunteered to partici...

description The purpose of this study was to examine the effects of six weeks of depth jump (DJ) vs. countermovement jump (CMJ) training on sand on muscle soreness, jump, sprint, agility and leg press strength. Thirty healthy men (age 20.4±1.1 years; height 177.4±5.1 cm; mass 72.8±9.7 kg) volunteered to participate and were randomly assigned to one of three groups: DJ training group (n=10), CMJ training group (n=10) or control group (n=10). The experimental groups performed either DJ or CMJ training two days a week for six weeks. The training program included five sets of 20 repetitions DJ (from the height of a 45-cm box) or CMJ exercise onto 20 cm of dry sand. Assessments of Vertical Jump Test (VJT), Standing Long Jump Test (SLJT), 20 and 40 m sprints, T-Test (TT), Illinois Agility Test (IAT), and one-repetition maximum Leg Press ([1RM.sub.LP]) were performed a week before and following the 6-week training period. Muscle soreness was also measured pre, immediately post, 24 and 48 hours after the first and last training sessions. Significant increases were observed in both the DJ and CMJ groups in VJT (16.2 vs. 13.5%), and SLJT (13.9 vs. 14.4%) (p

Only the CMJ group made significant improvements in [1RM.sub.LP] (p&lt;.05). The CMJ group had significantly greater perception of muscle soreness than the DJ and CG groups in the rectus femoris at 48 hours post the first training session (p&lt;.05). No significant differences were observed among groups in muscle soreness after the last training session (p&gt;.05). These observations may have considerable practical relevance for the optimal design of plyometric training programs, given that DJ and CMJ training on sand is effective for improving muscular performance. Key words: depth jump, countermovement jump, stretch-shortening cycle, muscle damage Cilj je ovog istrazivanja bio utvrditi ucinke sestotjednog treninga dubinskih skokova u odnosu na skokove s pripremom na pijesku na misicni zamor, izvedbu skokova, sprinta, agilnost i snagu noznog potiska. Za sudjelovanje u istrazivanju volontiralo je 30 ispitanika (dob: 20,4[+ or -]1,1 godina; tjelesna visina: 177,4±5,1 cm; tjelesna tezina: 72,8[+ or -]9,7 kg) koji su slucajnim odabirom rasporedeni u jednu od tri grupe: grupu koja je trenirala dubinske skokove (n=10), grupu koja je trenirala skokove s pripremom (n=10) ili kontrolnu grupu (n=10). Ispitanici u eksperimentalnim grupama provodili su trening dubinskih skokova ili trening skokova s pripremom dva puta tjedno tijekom sest tjedana. Program treninga ukljucivao je pet serija po 20 ponavljanja dubinskih skokova (saskok sa sanduka visine 45 cm) ili skokova s pripremom na suhom pijesku dubine 20 cm. Tjedan dana prije treninga te nakon sest tjedana treninga provedena su mjerenja visine vertikalnog skoka, skoka udalj s mjesta, sprinta na 20 i 40 metara, razine agilnosti pomocu T-testa i Illinois Agility Testa te 1RM u testu nozni potisak. Razina misicnog zamora takoder je bila mjerena prije, odmah nakon, 24 i 48 sati nakon prvog i posljednjeg treninga. Znacajna povecanja u visini vertikalnog skoka (16,2 vs. 13,5%) i skoku udalj s mjesta (13,9 vs. 14,4%) (p&lt;0,05) zabiljezena su u grupi koja je trenirala dubinske skokove, odnosno skokove s pripremom. Znacajna smanjenja vremena sprinta na 20 (8,5 vs. 7,4%) i 40 (6,1 vs. 3,8%) metara, T-testu (9,3 vs. 12%) i Illinos Agility Testu (9,2 vs. 10,6%) zabiljezena su u obje eksperimentalne grupe. Znacajno povecanje 1RM u testu nozni potisak zabiljezeno je samo u grupi koja je provodila trening skokova s pripremom. Ista grupa zabiljezila je i statisticki znacajno veci osjecaj misicnog zamora u misicu rectus femoris 48 sati nakon prvog treninga nego grupa koja je provodila trening dubinskih skokova i kontrolna grupa. Nisu zabiljezene statisticki znacajne razlike u osjecaju zamora izmedu grupa nakon posljednjeg treninga. Rezultati ovog istrazivanja mogu pridonijeti dizajniranju optimalnih programa pliometrijskog treninga, s obzirom na cinjenicu da su oba eksperimentalna tipa treninga na pijesku pokazala ucinkovitost u poboljsanju misicnih performansi.
