The Claim

Performing a 20-second loaded stretch between resistance training sets over an 8-week period yields a modest improvement in isometric plantar flexor strength, with the stretch condition producing gains of approximately 6 to 7 Newton-meters compared to control, demonstrating that loaded stretching enhances neuromuscular performance without compromising traditional strength development protocols in young, untrained men.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

Adding a short, weighted stretch between your workout sets can actually help your calf muscles get a little stronger over two months. This extra stretching boosts your muscle power without slowing down your regular strength training progress.

See the scientific wording

Incorporating a 20-second loaded stretch between sets of resistance training yields a modest improvement in isometric plantar flexor strength, with strength gains favoring the stretch condition by approximately 6 to 7 Newton-meters over 8 weeks in young, untrained men, demonstrating that loaded stretching can enhance neuromuscular performance without compromising traditional strength development protocols.

What the research says

1 study
  1. Study: Loaded inter-set stretch may selectively enhance muscular adaptations of the plantar flexors

    Adding a short stretch between exercise sets helped young men slightly improve their calf strength over eight weeks compared to just resting. This shows that stretching during workouts can boost muscle performance without getting in the way of regular training.
