Well-developed calf muscles not only attract attention and form a harmonious body shape, but also serve as the foundation for exercises such as squats, jumping, or running. Unfortunately, many people struggle to develop this muscle group. The reason for their lack of growth may be overly intense training and insufficient recovery, but there are also other, less obvious causes. This article discusses those.
Genetics affects the size of calf muscles
Many people claim that the size of calf muscles is almost entirely genetically determined, and there is some truth to that. Calf muscles are composed of 90% slow-twitch muscle fibers, which grow up to twice as poorly as fast-twitch fibers. When compared to thigh muscles, which are part of the quadriceps muscle group, the potential for calf muscles to synthesize muscle protein after training is only 42%. However, there is one more reason why calf muscles, especially the flat calf muscle, respond poorly to weight training. Calf muscles are responsible for maintaining an upright posture while walking and standing, which means they are active all day. As a result, calf muscles in non-athletic individuals are better developed than other muscle groups. However, it is not really a genetic factor, but rather the result of long-term activity. Therefore, apart from the muscle fiber composition, there are no other genetic reasons preventing calf muscles from growing properly. However, when planning a training program, experience and overall muscle development should be taken into account.
Alternative Priorities for the Calves
Every trainer has an exercise plan that develops the muscles of their hands, back, shoulders, and chest. The sequence of exercises they perform has a significant impact on both the immediate post-training effect and the long-term results. However, are they training them correctly? And how many of them devote an entire training session to their calf muscles? Brazilian researchers compared two training programs for the upper body that differed only in the sequence of exercises. In the first program, bench press was performed before the French press on the triceps, and in the second, the reverse. The result was that the first exercise produced greater results. In those performing the first program, the chest received more stimulation, while in the second case, the triceps received more stimulation. The first exercises determine where the greater hypertrophy occurs. After warming up, when the nervous system is still active, and the metabolites have not yet accumulated, the body is in an ideal state for adaptation. Meanwhile, during intense training, lactic acid is released, causing acidification of the blood - a side effect of insufficient oxygen to meet demand. The breakdown of muscle protein increases the ammonia level in the blood to such an extent that it exceeds the level in people with liver diseases, causing mild hypoxia in the brain and various neurological disorders. The muscle fibers and their connective tissues are torn, causing inflammation due to resistance. If you want these muscles to grow, you should give them as much time and energy as you do during training for the upper half of the body.
Work on the calves - incorrect exercise selection
Each muscle group has its key exercises that allow for the application of significant load and appropriate stimulation of the muscles for growth. In the case of the calf muscles, the ratio of the muscle's length to the Achilles tendon makes them more powerful when they are in a stretching position. It may be useful to perform the exercise of rising on the toes in such a way that the body is gently moved forward in the lower position. This causes tension in the calf muscles. Then, with a quick, jump-like movement, lift the body onto the toes.
How to effectively train the calf muscles?
Training the calf muscles should not occur more frequently than twice a week. It may be beneficial to designate a separate day for training these muscles, especially when difficulties with their growth arise. Individuals who do not have significant problems with this can continue calf muscle training after training the thigh muscles. If you are currently training your calves, it is advisable to change the order of strength training and cardio. Most bodybuilders perform aerobic training after completing strength training, but in the case of the calves, this is not an optimal solution. Note that after performing strength exercises on the lower leg muscles, cardio can have a negative impact on these muscles. Performing cardio before calf muscle training will cause the muscles to consider the aerobic effort as a warm-up and strength training will bring better results. Furthermore, it is important to pay attention to variation in exercises and continuous progress, as well as proper recovery.
