Anthropometry and gender influences on the arm swing's contribution to vertical jump heights

Differences in the Biomechanics of the Vertical Jumps in Young Adult Handball Players: Effect of the Countermovement and the Arm Swing

“…In addition, ASA was in reasonable agreement with past findings [10]. However, the absence of a sex difference in the ASA does not confirm past findings that males rather than females exhibit highest maximum jump heights when using an arm swing [4], [35]. This could be a result of the sporting background, as the upper limbs are actively used in the game of handball and thus the effective strength for the arm swing could be adequately applied.…”

“…By disallowing the use of an arm swing, a vertical jump test is believed to evaluate the power production capacity of the lower limbs [3]. However, a larger jumping height is observed when the CMJ is executed with an arm swing [4][5][6], [8], [12], [19], [35]. The increased CMJF performance is believed to be the outcome of the increment the load imposed on the leg muscles because of the arm swing [12], which, in turn, leads to increased force, power and work outputs [13].…”

“…Despite the fact that considerations have been expressed about the relevancy of the CMJ with the jump-related strength utilised in handball skills [23], the standardized vertical jumping tests remain a mean to assess conditioning in handball [4]. Under this perspective, the CMJF is considered to be an appropriate jump test to evaluate performance in handball because of its relevance with the sportspecific skills used in the game [20], [34].…”

Adölesan Voleybol Oyuncularında Core Stabilizasyon Egzersizlerinin Smaç Hızına Etkisi

“…Bu yukarı itişin sonunda pelvis rotasyonu, topa mümkün olan en yüksek hızda smaç yapabilmek için, gövde rotasyonu, hızlı omuz fleksiyonu ve el bileği hareketleriyle uçuş fazı sırasında transfer edilen momentumu oluşturur 4 . Smaç hızı için, pelvis ve gövdede momentum oluşumu ve omuz internal rotasyonu, fleksiyonu ve el bileği ekstansiyonunda yüksek açısal hızlara geçişin önemli olduğu bilinmektedir 5 . Smaç vurma esneklik, kas kuvveti, koordinasyon ve nöromüsküler etkinlik gerektiren kompleks bir harekettir ve direnç antrenmanları ile göğüs/omuz ve gövde güç ve kuvvetinin arttırılması ile geliştirilebilir 6 .…”
