Article Abstract
Introduction: This study aimed to test the contribution of trunk swing to the performance during fixed-seat rowing in eligible and non-eligible (NE) para rowers. Assessment of trunk swing is used to classify para rowers with physical disability in Para Rowing (PR) 1 and PR2 rowers. PR1 rowers are classified based on the demonstration of impaired function of trunk swing.
Methods: PR1, PR2, and NE rowers participated. Rowing ergometers were used in two different fixed-seating conditions, resulting in either (1) restricted trunk swing or (2) unrestricted trunk swing during the rowing stroke. Participants performed maximal effort 500 m pieces (race pace) in each seating configuration. Force production at the handle and fixed-seat rowing-specific trunk extension force was measured. Rowing performance measures were compared using a repeated-measures general linear model, including condition and group and an interaction between condition/group.
Results: Only PR1 rowers generated greater trunk extension force during the restricted condition compared with the unrestricted trunk condition ( < 0.01). The restricted trunk swing condition resulted in a faster time to complete 500 m and minimal impact on force production for PR1 rowers. NE and PR2 rowers showed a significantly faster time to complete 500 m and greater stroke impulse (Ns) in the unrestricted compared with the restricted trunk swing condition ( < 0.01).
Discussion: These results provide evidence-based reasoning for the classification of fixed-seat rowers. Contrary to PR2 and NE rowers, whose rowing performance was decreased due to trunk restriction, PR1 rowers' performance benefits from the trunk restriction.

Biomechanical characteristics of swing techniques using different clubs in college male golfers.
PLoS One

China Institute of Sport Science, General Administration of Sport of China, Beijing, China.
Background: Golf is a sophisticated sport that integrates precision, skillfulness, and strategic thinking, with swing techniques of different clubs exhibiting distinct biomechanical characteristics. This study aims to investigate the biomechanical characteristics of golfers' full swings with different clubs from kinematic and dynamics perspectives, thereby providing insights for optimizing full swing techniques.
Methods: Ten low-handicap right-handed college male golfers were recruited, and their full swing parameters with the driver, 5-iron, and 7-iron (each club was successfully collected 10 times) were synchronously collected using a 250 Hz infrared motion capture system and a 1000 Hz three-dimensional force platform.
Real-time and immediate effects of backward walking exercise on pain intensity and lumbopelvic movement control in individuals with chronic non-specific low back pain with lumbar flexion syndrome.

Objective: Backward walking may promote the preferential recruitment of lumbar extensors to optimize flexed spinal posture adopted LBP flexion subgroup. This cross-sectional study investigated the backward-walking exercise on a) real-time muscle activation, and b) its immediate effect on back pain intensity, movement control and lumbopelvic muscle activation in individuals with chronic non-specific LBP characterized with lumbar flexion syndrome.
Method: Thirty adults with chronic non-specific LBP with clinical manifestation of flexion syndrome received assessments of their movement control at static standing and during the five-minute forward walking test, conducted before and after a 15-minute treadmill walking training in forward or backward direction (as the immediate effect), while real-time adaptation of the lumbopelvic muscles during walking training was also evaluated.
Impacts of obstacle-crossing during walking on postural control strategies in individuals with functional ankle instability.

School of Physical Education and Sports, Soochow University, Suzhou, China.
Background: Lateral ankle sprains often progress to functional ankle instability (FAI). Obstacle-crossing could pose greater challenges for individuals with FAI due to significant impairments in ankle kinesthesia and joint position sense. While existing studies have focused on level-ground gait characteristics in FAI, the postural control strategies underlying obstacle-crossing remain unclear, and the impact of obstacle height on these strategies has not been investigated.

Background: The impact of levodopa on gait in individuals with Parkinson's disease (PD), particularly in those with and without a history of falls, remains unclear.
Objective: This study examines whether levodopa alters digital gait characteristics in fallers and non-fallers with PD to those observed in healthy controls (HC) and identifies key gait and turning measures most influenced by levodopa.
Methods: We recruited 33 individuals with PD (17 fallers, 16 non-fallers) and 17 HC.
Influencing factors on swing phase ground clearance in transfemoral prostheses - A biomechanical study.

Background: Prosthetic fittings for persons with a transfemoral amputation should provide adequate ground clearance (GC) during prosthetic side swing to minimize the risk of stumbling or falling. Insufficient ground clearance often leads to compensatory movements that consequently influence gait biomechanics negatively.
Research Question: How do different prosthetic components and alignment of a transfemoral prosthesis affect prosthetic side GC and compensatory strategies during level walking?
Methods: Eight persons with transfemoral amputation were enrolled.
