Performance Trajectory Related to Age, Classification, and Sex in Elite Kayak Para Canoe Athletes.

Objective: The aim of the study is to verify the performance trajectory related to age, classification (KL: kayak level; M: male; F: female), and sex of elite kayak Para canoe athletes.

Design: This is a retrospective cohort study.

Results: Race results and athletes' data were retrieved from publicly available online databases for 17 competitions and 102 finals between 2015 and 2022.

Influence of sensor mass and adipose tissue on the mechanomyography signal of elbow flexor muscles.

Mechanomyography (MMG) is a non-invasive technique that records muscle contraction using sensors positioned on the skin's surface. Therefore, it can have its signal attenuated due to the adipose tissue, directly influencing the results. This study evaluates the influence of different mass added to a sensor's assembly and the adipose tissue on MMG signals of elbow flexor muscles.
