The Claim
In resistance-trained women, countermovement jump height and bench press throw peak velocity are higher during the afternoon (17–19 h) compared to the morning (9–11 h), demonstrating diurnal variation in lower-body ballistic performance.
What the research says
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.
Resistance-trained women produce higher jump heights and faster barbell velocities in the afternoon than in the morning, indicating that lower-body explosive performance varies with time of day.
See the scientific wording
In resistance-trained women, countermovement jump height and bench press throw peak velocity are higher in the afternoon (17–19 pm) than in the morning (9–11 am), indicating a diurnal variation in lower-body ballistic performance.
As the body warms up during the day, muscles become more elastic and nerve signals to muscles fire faster, making jumps and explosive lifts stronger in the afternoon.
What the research says
1 studyEven though the study gave some women caffeine, it still found that women who lift weights jump higher and throw the bench press faster in the late afternoon than in the morning — just like the claim says.
