The Claim

In highly trained male tennis players, scheduling serve velocity, power, speed, and agility training sessions in the afternoon results in higher performance outcomes compared to morning sessions due to circadian-related physiological variations.

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

Highly trained male tennis players perform better in serve velocity, power, speed, and agility when training in the afternoon rather than in the morning.

See the scientific wording

Coaches and tennis players should schedule serve velocity, power, speed, and agility training sessions in the afternoon to optimize performance in highly trained male tennis players, based on observed circadian-related declines in these metrics during morning testing.

Why this might work

As the day progresses, the body's internal temperature rises, making muscles warmer and more elastic. This allows muscles to contract faster and stronger, nerves to send signals more quickly, and joints to move with less resistance, leading to better performance in explosive movements like serving, sprinting, and jumping.

  1. Study: Circadian rhythm effect on physical tennis performance in trained male players

    Scientists tested elite male tennis players in the morning and afternoon and found they served faster, jumped higher, and moved more quickly in the afternoon. So, it’s better to practice these skills later in the day.
