Exploring discrepancies in muscle analysis with ImageJ: understanding the impact of tool selection on echo intensity and muscle area measurements.

Purpose: The aim was to compare the use of different tools within the ImageJ program (polygon vs. segmented line) and their impact on the calculation of muscle area and echo intensity (EI) values in ultrasound imaging of the vastus lateralis muscle.

Methods: Thirteen volunteers participated in this study.

Contrast With Compression Therapy Enhances Muscle Function Recovery and Attenuates Glycogen Disruption After Exercise.

Background: Exercise-associated muscle damage (EAMD) temporally impairs muscle function and intramuscular glycogen storage. Contrast with compression (CwC) therapy provides localized EAMD treatment with minimal changes in core/tissue temperature that can impair glycogen resynthesis.

Hypothesis: CwC will enhance the recovery of strength, power, and joint mobility, reduce markers of EAMD, and attenuate the disruption of glycogen storage observed after damaging exercise.

Effectiveness of surf therapy for children with disabilities.

Background: Few researchers have examined the effects of surf programs on children with disabilities. Due to previous research findings, surfing is being used, as the focus of physical activity intervention due to its numerous health and therapeutic benefits.

Objective/hypothesis: The purpose of this study was to explore the effects of an eight-week surfing intervention on various physical fitness measures in 71 children with disabilities such as autism spectrum disorder, down syndrome, global developmental delays, and cerebral palsy.
