Aman: 6-day Prague forehand development
Aman is a competitive adult player from the United States. He joined Stakhovsky Tennis in Prague for a focused 6-day training block.
During 6 days, Aman's average forehand ball speed increased from 91 km/h to 104 km/h, a gain of 13 km/h or 14.3%. His maximum forehand ball speed increased from 103 km/h to 114 km/h, a gain of 11 km/h or 10.7%.
Evidence status: These are first-party measurements from a 6-day Stakhovsky Tennis training block in Prague. The source does not state the device, measured sample size, test protocol, ball type, court surface, exact dates, daily training volume, or independent validation.
Overview
Aman is a competitive adult player from the United States. He joined Stakhovsky Tennis in Prague for a focused 6-day training block.
The goal was to improve his forehand speed through structured technical work and measure whether the improvement appeared across the measured shot sample, not only in one maximum-speed attempt.
Measurement approach
The assessment tracked two forehand metrics at the start and end of the block: average ball speed and maximum ball speed.
Maximum speed shows the player's highest output. Within this assessment, average speed is the stronger repeatability signal because it shows whether the measured shot sample shifted to a higher speed level.
Measured improvements
| Forehand metric | Start | Finish | Improvement |
|---|---|---|---|
| Average forehand ball speed | 91 km/h | 104 km/h | +13 km/h / +14.3% |
| Maximum forehand ball speed | 103 km/h | 114 km/h | +11 km/h / +10.7% |
During the 6-day block, Aman's average forehand ball speed increased from 91 km/h to 104 km/h. This was a gain of 13 km/h, or 14.3%.
His maximum forehand ball speed increased from 103 km/h to 114 km/h. This was a gain of 11 km/h, or 10.7%.
Why the average-speed result matters
The strongest result was the increase in average speed. The improvement was not limited to one faster shot. Aman's measured forehand sample shifted to a higher speed level.
Within this assessment, that is a stronger repeatability signal than maximum speed alone. It does not establish match consistency or accuracy.
Coaching conclusion
Aman's 6-day result shows what a focused training block can achieve when technical work is supported by clear measurement.
The Stakhovsky Tennis approach is to identify the highest-impact priorities, train them with structure, measure the change, and test whether the improvement is repeatable.
Key takeaway
Average forehand speed: +14.3% | Maximum forehand speed: +10.7%
Both improvements were measured during a 6-day Prague training block.
Method and limits
The assessment compares average and maximum forehand ball speed at the start and end of the 6-day block. The source does not state the device, sample size, ball-feed method, test protocol, ball type, court surface, exact dates, daily training volume, or raw shot data. The results apply to Aman and this block. They do not establish a change in accuracy, control, or match performance and do not promise the same result for another player. The source does not provide independent validation.
