Forehand strike
A strike executed with a forehand grip, which is the most basic, powerful, and commonly used shot in badminton.
Forehand strikes are characterized by high shuttlecock speed, strong power, and precise control over placement and trajectory.
Backhand strike
A strike executed with a backhand grip, which is generally considered more difficult to master than the forehand strike, especially in the backcourt.
Due to body mechanics, shots played on the backhand side are less fluid in power generation, with limitations in both strength and control. The general strategy among high-level athletes is to use the forehand whenever possible.
Overhand strike
A strike executed with a downward-moving racket swing following an upward curve path, such as clear, drive, or smash.
Overhand strikes are characterized by easy power generation, high shuttlecock speed, good court visibility, flexible shot selection, and strong direct scoring ability.
Underhand strike
A strike executed with an upward-moving racket swing following a downward curve path, such as lift and net shot.
Underhand strikes are an important defensive technique when a player is in a passive situation.
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 shuttlecock.
To generate powerful and fast shots, attention must be given to coordinating several factors:
Ensure proper coordination between the upper and lower limbs and torso, with controlled muscle tension and release, focusing the power so that the explosiveness is transferred through the racket to the shuttlecock at the moment of impact.
The preparation swing should be smooth and efficient, leaving space to accelerate, with the shuttlecock hit at the moment when the racket speed is at its maximum.
Choose the optimal point of contact and angle for the shot.
Hit the shuttlecock with the racket's proper face.
Quickly return the racket to be ready for the next shot.

Active duration
Total time spent moving, preparing swings, and hitting the ball during this session.
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 percentage and force average of overhand strikes.
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.
