The combined strength of standardized lab sprint testing and wheelchair mobility field testing in wheelchair tennis players.

Objective: This cross-sectional study examined associations between wheelchair sprint and anaerobic power (measured in the lab) and wheelchair mobility performance (measured in the field) among two groups of wheelchair tennis players. Additionally, construct validity was assessed for both lab and field tests.

Design: Nine amateur and nine elite wheelchair tennis players performed a Sprint and Wingate test on a wheelchair ergometer in the lab and a Sprint, Illinois and Spider test in the field, with inertial measurement units on their wheelchairs.

ImmuNet: a segmentation-free machine learning pipeline for immune landscape phenotyping in tumors by multiplex imaging.

Tissue specimens taken from primary tumors or metastases contain important information for diagnosis and treatment of cancer patients. Multiplex imaging allows visualization of heterogeneous cell populations, such as immune cells, in tissue samples. Most image processing pipelines first segment cell boundaries and then measure marker expression to assign cell phenotypes.

Long-term trajectories of physical activity behavior in adults with physical disabilities and/or chronic diseases following rehabilitation: the prospective cohort study ReSpAct 2.0.

Purpose: This study aimed to identify trajectories of physical activity behavior from discharge up to 6-8 years after rehabilitation among adults with physical disabilities and/or chronic diseases, and to determine modifiable determinants associated with trajectory membership.

Material And Methods: 390 Adults with physical disabilities and/or chronic diseases participated in the Rehabilitation, Sports and Active lifestyle (ReSpAct) 2.0 study with measurements at 3-6 weeks before discharge (T0), and 14 (T1), 33 (T2), and 52 weeks (T3), and 6-8 years (T4) after discharge from rehabilitation.

The Effect of a Newly Developed Hand Rim on Mobility Performance and Propulsion Technique in Wheelchair Tennis Players.

Purpose: To investigate the effect of a newly developed hand rim in wheelchair tennis players from a lab and field perspective.

Methods: Nine wheelchair tennis players performed a set of field and lab tests with the new rim (NR) and regular rim on the racket side. Each player had a 60- to 120-minute regular training session with the NR.
