Racket swing times within a certain range during exercise.
Unit: times.
Continuous swings
Continuous swing times during exercise.
Unit: times.
Forehand strike
A strike executed with a forehand grip.
Forehand strikes are characterized by high speed and strong power.
For right-handed grips, the ideal contact point is in front of the body on the right side, around peak height.
Backhand strike
A strike executed with a backhand grip.
Backhand strikes are characterized by deceptive and sudden shots.
For right-handed grips, the ideal contact point is slightly left of center in front of the body, from the rising phase to near peak height.
Swing strength
Force applied to the racket by the hitting hand during a swing.
Greater swing power allows for faster shots, increasing the difficulty for the opponent to return the ball. To hit powerful, high-speed shots:
Coordinate your upper limbs, lower limbs, and trunk. Don't rely only on the wrist or arm strength. Engage muscles in a smooth, controlled sequence to focus power.
The preparation swing should be smooth and efficient.
Choose the optimal point of contact and angle for the shot.
4 Quickly return the racket to be ready for the next shot.
Unit: Newton.
Ball speed
The speed of the ball as it travels through the air after being hit.
Faster ball speed makes returns more difficult for opponents.
Unit: km/h.
Shot efficiency
Evaluates how effectively swing power is transferred to the ball, based on both swing power and ball speed. Higher efficiency indicates better control of the ball.
Rally distribution
Analyzes shot count and strike types to calculate the proportion of offensive, neutral, and defensive rallies in this session, helping you understand your playing style.
Offensive rally: You take the initiative, control the pace, and clearly aim to score.
Defensive rally: You focus on defense—such as blocks and chops—to handle incoming shots and stay consistent.
Neutral rally: Both sides are evenly matched, with extended exchanges and a balanced offense-defense dynamic.
Exercise performance
An overall evaluation of this session based on offense, endurance, explosive power, confrontation, exercise, and power.
Offensive index: This index is to assess your offensive performance during the sport. It is calculated based on the swing speed and strength. The faster the swing speed and the greater the swing strength, the higher the offensive index.
Endurance index: This index is to assess how long your body can endure the sport. It is calculated based on the number of swings. The more swings you make, the higher the endurance index.
Explosive power index: This index is to assess your ability to generate explosive force in a short time. It is the comprehensive performance of your power, speed, technique, agility, and coordination.
Confrontation index: This index is to assess the intensity of the confrontation during the sport. It is calculated based on the swing frequency. The higher the swing frequency, the higher the confrontation index.
Exercise index: This index is to assess your aerobic exercise effects during the entire sport. It is calculated based on the aerobic exercise effects.
Power index: This index is to assess your strike strength and accuracy during the sport. It is calculated based on the top swing strength values in each sport.
