Contagious Crying Revisited: A Cross-Cultural Investigation Into Infant Emotion Contagion Using Infrared Thermal Imaging.

Contagious crying in infants has been considered an early marker of their sensitivity to others' emotions, a form of emotional contagion, and an early basis for empathy. However, it remains unclear whether infant distress in response to peer distress is due to the emotional content of crying or acoustically aversive properties of crying. Additionally, research remains severely biased towards samples from Europe and North America.

Lower limb gait joint coordination variability in people with diabetes-related foot ulcers.

Background: Diabetes-related foot ulcers pose substantial health risks globally, yet the biomechanical intricacies underlying their development remain incompletely understood. This study aimed to evaluate lower limb gait joint coordination variability in individuals with diabetes-related foot ulcers compared to those with diabetes (without diabetes-related foot ulcers) and healthy controls.

Methods: A total of 99 participants (diabetes-related foot ulcers cases - 16, Diabetes controls - 50, Health controls - 33) compared three self-paced walking trials.

Impart backspin and pitch the ball up: strategies cricket fast bowlers can employ to generate late swing.

In cricket fast bowling, late swing can increase interception difficulty for opposition batters. However, little is known about the occurrence and cause of late swing. This study investigated ball kinematics and the effect of changing kinematics on late swing with new cricket balls.

Relationships between upper trunk rotation kinematics and arm fatigue after repetitive pitching among baseball pitchers.

Early upper trunk rotation during baseball pitching has been associated with higher upper-limb kinetics. However, its relationship with arm fatigue after repetitive pitching is unclear. This study aimed to investigate associations between upper trunk rotation kinematics and arm fatigue.

What gaps exist in biomechanics and motor control research in Paralympic sports? A scoping review focussed on performance and injury risk.

In Paralympic sport, athletes, coaches and administrators seek medal-winning outcomes. Research in the fields of biomechanics and motor control can support the quantification of performance measures and injury risk. The aim of this article is to review the state of existing research and identify gaps offering researchers and practitioners targeted paths for creating competitive advantages.
