Squatting with elastic bands (accommodating resistance) is likely more effective than constant-load squatting for improving jump performance.

The idea is based on the concept of accommodating resistance, where tension increases as the movement extends, which better matches the strength profile of the lower limbs. Research (studies on post-activation performance enhancement or PAPE) shows that this method can induce an immediate and superior improvement in power and jump height compared to traditional free weights, notably due to better stimulation of the nervous system (Scott et al., 2018; PubMed 2024 study). However, the term "better" must be nuanced: while acute performance gains are documented, long-term studies do not always confirm a systematic superiority for increasing maximal strength (1RM) compared to well-structured free-weight training. Potential exaggeration lies in the idea that bands are a universal miracle solution, whereas effectiveness strongly depends on individualization and managed fatigue. There is no evidence that this method completely replaces the fundamentals, and it is primarily used as a specific tool for already-trained athletes.
