Keiser Seated Calf
The Best Seated Calf Raise Machine On The Market.
The Keiser Seated Calf machine is a piece of strength training equipment designed to target and strengthen the calf muscles, especially the soleus.
The Keiser Seated Calf was designed to enhance the training of Long Jump world record holder Mike Powell, as well as for Willie Banks. Mike's coach Randy Huntington needed a more effective way to develop the calf muscles of his athletes, and Keiser came through an innovating and remarkably effective machine for developing the calves.
For athletes who want to sprint faster, especially during acceleration, the Keiser Seated Calf should be a mainstay in their arsenal of strength training equipment.
Where To Buy The Keiser Seated Calf Machine
The Keiser Seated Calf is available through SimpliFaster. You can purchase the machine outright, or use their installment option to pay for the machine over time.
Keiser Seated Calf - Pneumatic Resistance
What sets the Keiser seated calf raise apart from other calf machines is its use of Keiser's pneumatic air resistance system. Instead of using traditional weight plates or a weight stack, the Keiser seated calf machine uses compressed air to provide resistance.
Air resistance is isotonic, meaning that the load will stay the same regardless of how fast you move it or where in the movement you are. Because air resistance has no inertial qualities, athletes can rapidly switch between eccentric and concentric muscle actions, allowing for higher loads to be used at higher velocities compared to if one was training with a mass based system.
On a typical seated calf raise, the load gets lighter at the top and heavier at the bottom due to momentum and inertia. This leads to feeling too much resistance at the bottom of the movement, and not enough resistance at the top of the movement.
Overall, the Keiser seated calf machine can be an effective tool for strengthening the calf muscles and improving athletic performance, especially for sprinters or other athletes who have to run fast in their sport.
Why Seated Calf Raises Are Important For Athletes
The seated calf raise is a staple exercise for sprinters or any other athlete who needs to improve their acceleration sprinting. While tempo running and upright calf raises target the gastrocnemius, the soleus muscle is often underdeveloped in athletes.
Because of this, athletes have trouble stabilizing the ankle during acceleration, leading to poor ankle stiffness and force transfer. If you ever see your athletes' ankles collapse during acceleration, it is likely that they need to improve their soleus strength as well as their skills regarding foot placement.
The soleus muscle is an important muscle in the lower leg that plays a crucial role in sprinting. The soleus muscle is located in the back of the lower leg, below the knee joint, and it connects the tibia and fibula bones to the heel bone (calcaneus) via the Achilles tendon.
During sprinting, the soleus muscle works in conjunction with other muscles in the leg to generate force and power the movements of the foot and ankle. The soleus helps set the ankle joint up so that the gastrocnemius can do its job. Specifically, the soleus muscle functions to plantarflex the ankle, meaning it helps to point the toes downward and push off the ground during the propulsion phase of the sprint stride.
As the foot contacts the ground during the sprint, the soleus muscle contracts eccentrically to absorb the impact of the landing and then rapidly contracts concentrically to generate force and propel the body forward. The ability of the soleus muscle to generate rapid, powerful contractions is critical for explosive sprinting movements.
Strengthening the soleus muscle can be an important aspect of sprint training and can help to improve sprint performance. Exercises like calf raises and plyometric jumps can be effective in targeting the soleus muscle and improving its strength and power.
Personally, I have found that doing bent leg calf extensions with Keiser equipment has led to massive improvements in power outputs through the ankle. This has helped to improve my acceleration, and it didn't even require that much work! By incorporating 3 sets of 10-15 quick repetitions at the end of my workouts, I saw major improvements in soleus function.
