Pre-workout warmup with an elastic resistance band (band squat) is just as effective as the barbell box squat, in augmenting acute jump power, according to research from the Journal of Strength and Conditioning Research. Both modes of warmup were superior to static stretching.
Power output significantly decreased from pre-warmup to post-warmup for the static stretch protocol. The static stretch was detrimental to jump performance. There is a consensus in the scientific literature to suggest a negative relationship between static stretching and acute power performance (sprinting, jumping, etc.).
The barbell box squat protocol involved 3 sets of 3RM; the band squat protocol involved 3 sets of 3 repetitions using highest resistance elastic bands; and the static stretch protocol used two 30-second stretches of muscles of the lower limbs.
Since elastic resistance bands are relatively inexpensive, portable, and accessible (compared to less transportable equipment like squat racks and free weights), strength and conditioning professionals may consider them for athletes training at various competition levels.
