Abstract:
Resistance training (RT) in post-operative cardiac rehabilitation (CR) complements aerobic exercise, enhancing physical capacity, independence, and quality of life. Traditionally, RT is delayed 6-8 weeks to reduce risks such as sternal instability and impaired healing after median sternotomy. However, emerging evidence suggests early RT (≤4 weeks) may be safe and beneficial for selected patients, improving recovery and functional outcomes. This paper explores the debate between traditional delay and early initiation, weighing potential benefits against risks to safety and healing. With growing support for early RT, should conventional timelines be reconsidered to optimize rehabilitation and long-term health?

A vector multiplied by a scalar value is called scalar multiplication. The result obtained is a new vector with a different magnitude. If the scalar is positive, the direction of the vector remains the same, but if it is negative, the direction of the vector is reversed. For example, the product of the mass and velocity yields the momentum.
