Correlations between agility and unilateral and bilateral power output in female soccer players (English)
Abstract [sv]

Bakgrund: Unilateral benträning är ett relativt outforskat område inom träningsvetenskapen. Traditionellt genomförs fysträning för intermittenta idrotter bilateralt, trots att idrottens rörelser sker unilateralt. Det finns många studier som behandlar samband mellan agility och effektutveckling, men få som har undersökt skillnaden mellan unilateral och bilateral effektutveckling sett till agility.

Syfte: Syftet med denna studie var att undersöka om unilateral effektutveckling har en starkare korrelation med agility än vad bilateral effektutveckling och agility har hos kvinnliga fotbollsspelare i division 2.

Metod: Kvinnliga fotbollsspelare (n=13, ålder 23 ± 4 år) utförde vertikalhopp med tilläggsbelastning på båda benen, vänster ben och höger ben på 20 kg, 30 kg, 40 kg samt för båda benen på 50 kg och T-test och Pro agility test. Effektutveckling i förhållande till kroppsvikten på båda benen (PBbw), vänster ben (PVbw) och höger ben (PHbw) analyserades och korrelerades sedan mot T-test (Ttest) och Pro agility test (Proagility).

Resultat: Signifikanta korrelationer hittades mellan agility och både vänster unilateral (PVbw-Ttest, r = -0,578) och bilateral (PBbw-Ttest, r = -0,741; PBbw-Proagility, r = -0,555) effektutveckling, där korrelationen bilateralt var starkast. Ingen signifikant korrelation hittades mellan höger ben och agility.

Konklusion: Bilateral effektutveckling hade en starkare korrelation med agility än vad unilateral effektutveckling och agility hade hos kvinnliga fotbollsspelare i division 2.

Abstract [en]

Background: Unilateral training is considered to be a new field of interest within the science of sports. Traditionally most of the strength and conditioning training is performed bilaterally even though the majority of motions in sports are carried out unilaterally. Previous studies have examined the correlations between agility and power output but few of them investigated the difference between unilateral and bilateral power output and agility.

Objective: The aim of this study was to examine whether the correlation between unilateral power output and agility is stronger than the correlation between bilateral power output and agility in female division 2 soccer players.

Method: Female soccer players (n=13, age 23 ± 4 years) performed loaded counter movement jumps with 20 kg, 30 kg and 40 kg for both legs, left leg and right leg and with 50 kg for both legs and T-test and Pro agility test. Power output, in relation to body weight for both legs (PBbw), left leg (PVbw) and right leg (PHbw) was analyzed and correlated against T-test (Ttest) and Pro agility test (Proagility).

Results: Significant correlations were found between agility and both left unilateral (PVbw-Ttest, r = -0,578) and bilateral (PBbw-Ttest, r = -0,741; PBbw-Proagility, r = -0,555) power output, where the bilateral correlation was the strongest. No significant correlation was found between the right leg and agility.

Conclusion: Bilateral power output had a stronger correlation with agility than unilateral power output and agility in female division 2 soccer players.
