Title Akutni utjecaj submaksimalnog predopterećenja na maksimalni broj ponavljanja pri izvedbi vježbe nožni potisak Title (english) Acute response of post-activation performance enhancement on maximal number of repetitions in leg press exercise Author Lana Papiga Mentor Jere Gulin (mentor)Committee member Jere Gulin (predsjednik povjerenstva)Committee member Saša Vuk (član povjerenstva)Committee member Josipa Nakić (član povjerenstva)Granter University of Zagreb Defense date and country 2024-09-24, Croatia Scientific / art field, SOCIAL SCIENCES Abstract Submaksimalno predopterećenje (PAPE) fenomen je gdje dolazi do povećanja mišićne snage i izvedbe kojem prethodi visoko-intenzivni podražaj u vidu vježbe s opterećenjem koja je biomehanički slična pokretu kojeg se želi potencirati. Njegov utjecaj na voljni mišićni otkaz nije jednoznačno utvrđen, naročito u ženskoj populaciji. Stoga je cilj ovog rada definiranje utjecaja PAPE (90% 1 maksimalnog ponavljanja, 1RM-a) na voljni mišićni otkaz pri izvedbi vježbe nožni potisak (na 70% 1RM-a) kroz broj
... More ponavljanja različitih serija te time i na ukupan trenažni volumen kod žena. Uzorak ispitanika uključivao je 14 žena (dob 23,5 ± 1,9 godina; tjelesna masa 61,4 ± 7,9 kg; visina tijela 165 ± 6,2 cm) bez mišićno-koštanih ozljeda ili drugih zdravstvenih problema čija je srednja vrijednost potisnutoga 1RM-a iznosila 155 ± 31,9 kilograma, a prijavljeno iskustvo u treningu s otporom bilo je 5,5 ± 3,3 godine. Protokol istraživanja sastojao se od 3 dolaska od kojih se prvi put testirao 1RM, a druga dva puta, nasumičnom podijelom u 2 grupe (temeljem abecednog reda prezimena), provodio kontrolni (KON) i eksperimentalni (PAPE) dolazak kada su se izvodile 3 radne serije do otkaza na 70% 1RM-a nakon 8 minuta pauze. Rezultati nisu utvrdili statistički značajnu razliku u broju ponavljanja prve i druge serije te ukupnog volumena, dok se ta razlika unutar treće radne serije pokazala statistički značajnom (p = 0,037). Ipak, upitno je može li se takav rezultat pripisati PAPE-u s obzirom na duge pauze između serija i vrijeme potencijacijskog djelovanja PAPE. Heterogenost grupe ispitanica po pitanju trenažnog iskustva potencijalni je razlog raspršenosti i time neujednačenosti rezultata u odnosu na prethodna istraživanja te se u budućnosti savjetuje individualiziranje pauza ispitanica. Iako spol ne bi trebao imati značajan utjecaj na ishod rezultata, čini se da žene ostvaruju manje koristi od PAPE-a u pogledu voljnog mišićnog otkaza. Less Abstract (english) Post-Activation Performance Enhancement (PAPE) is a phenomenon which leads to muscle strength and performance increasement following a high-intensity stimulus in the form of a loaded exercise which is biomechanically similar to the movement being potentiated. Its impact on voluntary muscle failure has not been clearly established, especially in the female population. Therefore, the aim of this study is to define the impact of PAPE (90% of 1 maximum repetition, 1RM) on voluntary muscle
... More failure during the leg press exercise (at 70% of 1RM) through the number of repetitions in different sets, and thus on the total training volume among women. The sample included 14 women (age 23.5 ± 1.9 years; body mass 61.4 ± 7.9 kg; body height 165 ± 6.2 cm) without musculoskeletal injuries or other health problems, with an average leg press 1RM of 155 ± 31.9 kg and reported resistance training experience of 5.5 ± 3.3 years. The research protocol consisted of three visits. During the first visit, the 1RM was tested. For the subsequent two visits, participants were randomly divided into two groups based on the alphabetical order of their last names. These visits included a control session (CON) and an experimental session (PAPE), during which participants performed three working sets to failure at 70% of their 1RM after an 8-minute rest. The results did not show a statistically significant difference in the number of repetitions in the first and second sets and the total volume, while the difference in the third working set was statistically significant (p = 0.037). However, it is questionable whether this result can be attributed to PAPE considering the long rest periods between sets and the potentiation duration of PAPE. The heterogeneity of the participants' training experience is a potential reason for the dispersion and thus the inconsistency of the results compared to previous studies, and it is advised to individualize rest periods in future studies. Although gender should not play a significant role in the outcomes, women may experience fewer benefits from PAPE regarding voluntary muscle failure. Less Keywords
