The article presents a study which compares the knee isokinetic profile in female athletes with and without patellofemoral pain syndrome (PFPS) after anterior cruciate ligament (ACL) surgery. It attempts to understand the characteristics and prognosis of PFPS after ACL reconstruction. Results of the study found an unbalanced strength of the knee masculature in female athletes after soft tissue graft.

The article presents a study aimed to evaluate the variability of humerothoracic joint kinematic pattern in a highly skilled player when serving his own racket. The study is undertaken through the use of a non-professional competitive male tennis player. The results of the study conclude that the changes in racket specifications affect the variability of humerothoracic angle patterns.

The article discusses a study which examines the frequency signal in the vibratory behaviour of tennis racket after the impact produce by tennis forehand drive. The study used a wireless tri-axial accelerometer to gather data while a Fourier transform algorithm is used to identify the forehand drive impact's frequency content. Results show higher signal energies in the out-of-plane direction compared to longitudinal and transverse axes.

The article presents a study aimed to compare the bilateral scapular kinematics during scaption among girls engaged in intensive tennis practice. The study is undertaken through the participation of 12 healthy girl tennis players. The results of the study show that the scapular kinematics patterns differ between the nondominant and dominant sides that suggest tennis-specific adaptations at dominant shoulders.

The article discusses a study which examines the scapulothoracic kinematics during scaption in young tennis players when holding a tennis racket or not. The study found that holding a racket does not affect the anterior tilt and scapular internal rotation during scaption. It states that the presence of a racket led to the increase in scapular upward when raising an arm.

The article examines the effect of additional loads on torques during giant swing on the high bar. The additional loads were attached to the gymnast's upper limbs, torso or lower limbs. The article shows that the presence of the additional loads caused changes in kinematics. It also shows that the net joint torques generated during the giant circle were also affected.
