respiratory system increase in tidal volume, vital lung 
capacity, and diffusion ability (Sebastianus, 2011) 
When a soccer player runs dribbling, the leg 
muscles must be able to withstand the weight of the 
body and protect the ball from the opponent's 
interference. Systematic training is training that is 
repeated and planned carefully and carried out 
according to the schedule applied. Athletes' muscle 
strength and agility can be increase using weight 
training. Various opinions say that leg muscle strength 
to running speed is one of the physical components 
used when playing football, especially in dribbling 
(Patraserasah, 2017). 
Ankle weight can increase agility in football 
players. Weight training in the ankle weight is one of 
the methods to improve physical condition, and the 
muscles will contract and become stronger. 
Neurotransmitters release acetylcholine and then 
delivered to the muscle membrane and stimulate the 
sarcoplasmic reticulum to release calcium and then 
binds troponin, causing ductal actin and myosin to 
pull, resulting in muscle contraction. Weight training 
will be added with the aim that muscle strength will 
be more effective if given a slight load above its 
ability, it aims to adapt the functional body so that 
there is an increase in muscle strength and indirectly 
power and flexibility will also increase, where power 
and flexibility are combined in agility (Hudriah, 2018) 
One of the supporting factors to Dribbling is leg 
muscle strength when players run by dribbling, and 
leg muscles can hold the load and balance the body for 
better movement (Lutan, 2006). Ankle weight 
exercise is used to increase the strength of leg 
muscles. Weight training with ankle weight exercise 
is included in isotonic movements because, during 
contractions, there is a constant tension with changes 
in muscle length (Riyadi, 2008). Isotonic movements 
contract with the same tension or weight constantly 
with changes in muscle length (Sidik & Giriwijoyo, 
2014) 
Weight training causes muscles to become 
hypertrophy, thereby increasing volume in each 
muscle fiber, increasing the number of blood vessels 
in muscle fibers and cell organelles in muscles 
(Kalangi, 2014; Sidik & Giriwijoyo, 2014). This 
enlargement occurs because of the increase in 
contractile elements in the fibers, causing increased 
strength of muscle contraction or active strength of 
muscles, thickened sarcolemma, increased connective 
tissue between muscle fibers, which can increase 
muscle strength and increase running speed (Sidik & 
Giriwijoyo, 2014). The hypertrophy in the muscles 
causes the formation of new muscle fibers, and 
mitochondria have increased (Colson & Collison, 
1983). Mitochondria play a role in the formation of 
ATP for the action of actin and myosin faster, so that 
muscle contraction is faster. Mitochondria also play a 
role in providing energy for the process of muscle 
contraction and increased muscular endurance (Birch 
K., McLaren D., 2005; Guyton & Hall, 2006) 
This ankle weight exercise causes hypertrophy in 
muscle cells, which can increase muscle strength and 
power. Running speed has elements of good muscular 
strength and leg power. This ankle weight exercise 
uses the De Lorme method with a load of 10 RM with 
eight sets (Lesmana, 2005) 
Long passing to be effective in their movements 
because one of the supporting factors is leg muscle 
strength when the player passes the ball the leg 
muscles can hold the load and balance the fulcrum of 
the body to be more precise when kicking the ball over 
long distances (Lutan, 2006). Ankle weight exercise 
is used to increase leg muscle strength used for 
running, namely m. Quadriceps femoris, m. Gluteus 
maximus, m. Iliopsoas, m. Hamstring, m. Triceps 
surae. 
The research of Radjiku et al. (2013) is a relevant 
study to this research, and there is the effect of ankle 
weight training on increasing the power of long 
passing kicks in the soccer game of male students in 
class VII. 
4 CONCLUSION 
Ankle weight exercise effective to increase football 
player's agility, speed, and long passing power
