Resistance training is an important part of any athlete’s rehabilitation program, helping to restore strength and function after an injury. However, not all types of resistance training are equally effective for rehabilitation. In this blog post, we’ll explore the three main types of resistance training used in physical therapy—isometric, isotonic, and isokinetic—and discuss how to choose the right one for your recovery.

Understanding Different Types of Resistance Training

Isometric Training

Isometric training involves engaging a muscle without changing its length. This means that while the muscle is working, the joint remains static. Isometric exercises are often used in the early stages of rehabilitation when movement may cause pain or further injury.

Benefits of Isometric Training

  1. Pain Reduction: Research has shown that isometric exercises can help reduce pain in certain conditions, such as tendinopathies.
  2. Strength Maintenance: Isometric training can help maintain muscle strength during periods of inactivity, preventing muscle atrophy.
  3. Joint Stability: By strengthening the muscles around a joint without moving it, isometric exercises can improve stability and support.

Examples of Isometric Exercises

  • Wall Sits: Stand with your back against a wall and slide down into a seated position, keeping your knees directly above your ankles. Hold this position for 30 seconds to a minute.
  • Planks: Lie face down, then lift your body off the ground using your forearms and toes. Keep your body in a straight line from head to heels for as long as possible.
  • Isometric Bicep Holds: Hold a weight in your hand with your elbow bent at 90 degrees. Keep your forearm still while trying to lift the weight higher with your bicep.

Isotonic Training

Isotonic training involves moving a muscle through a range of motion against a constant load. There are two types of isotonic contractions:

  • Concentric: The muscle shortens as it contracts, like lifting a weight.
  • Eccentric: The muscle lengthens while under tension, like lowering a weight.

Benefits of Isotonic Training

  1. Functional Strength Development: Isotonic exercises mimic the movements used in daily activities and sports, building strength in a functional manner.
  2. Improved Joint Range of Motion: By moving a joint through its full range, isotonic exercises can help improve flexibility and reduce stiffness.
  3. Enhanced Muscle Coordination: Isotonic training improves the coordination between different muscle groups, enhancing overall movement efficiency.

Examples of Isotonic Exercises

  • Bicep Curls: Stand or sit with a weight in one hand. Keeping your elbow close to your body, lift the weight towards your shoulder, then lower it back down.
  • Squats: Stand with your feet shoulder-width apart. Bend your knees and lower your body as if sitting in a chair, then stand back up.
  • Leg Press: Using a leg press machine, push a weighted platform away from your body by extending your legs, then slowly return to the starting position.

Isokinetic Training

Isokinetic training uses specialized equipment to maintain a constant speed of movement, regardless of the force applied. This type of training is often used in rehabilitation settings due to its ability to provide resistance throughout the entire range of motion.

Benefits of Isokinetic Training

  1. Safe for Injured Muscles: Because the speed of movement is controlled, isokinetic training can be safely used even when a muscle is injured.
  2. Detailed Feedback: Many isokinetic machines provide real-time feedback on the strength and endurance of the muscle being exercised.
  3. Customized Rehabilitation: The resistance can be tailored to the individual’s strength, making it suitable for all levels of fitness.

Examples of Isokinetic Exercises

  • Isokinetic Leg Extensions: Using an isokinetic machine, extend your leg against the machine’s resistance. The machine will adjust as you gain strength.
  • Isokinetic Shoulder Rotations: While seated, use an isokinetic machine to rotate your arm inwards and outwards against constant resistance.
  • Isokinetic Knee Flexion: Similar to leg extensions, this exercise involves bending your knee against the machine’s resistance, helping to strengthen the hamstrings.

Resistance training is a vital component of physical therapy rehabilitation programs for athletes recovering from injuries. Athletes are encouraged to work closely with qualified physical therapists who specialize in tailoring resistance training programs to individual circumstances. By doing so, they can ensure a safe and effective return to their pre-injury performance levels.
