Validity and reliability of trunk and lower-limb kinematics during squatting, hopping, jumping and side-stepping using OpenCap markerless motion capture application.

OpenCap is a web-based markerless motion capture platform that estimates 3D kinematics from videos recorded from at least two iOS devices. This study aimed to determine the concurrent validity and inter-session reliability of OpenCap for measuring trunk and lower-limb kinematics during squatting, hopping, countermovement jumping, and cutting. Nineteen participants (10 males, 9 females; age 27.

The relationship between executed cut angle and speed with lower extremity joint angles during unanticipated side-step cutting in soccer players.

Background: Certain movements patterns have been indicated in knee injuries during cutting while running tasks. Differences in the executed cut angle (ECA) could partially account for group differences in joint kinematics previously observed, including sex differences.

Research Question: Are there relationships between joint angles with entry speed and ECA during side-step cutting in soccer players?

Methods: This cross-sectional study recruited 21 (10 females) soccer players.

Food contamination with fipronil alters gene expression associated with foraging in Africanized honey bees.

Taking into consideration that bees can be contaminated by pesticides through the ingestion of contaminated floral resources, we can utilize genetic techniques to assess effects that are scarcely observed in behavioral studies. This study aimed to investigate the genetic effects of ingesting lethal and sublethal doses of the insecticide fipronil in foraging honey bees during two periods of acute exposure. Bees were exposed to fipronil through contaminated honey syrup at two dosages (LD = 0.

Intake of imidacloprid in lethal and sublethal doses alters gene expression in Apis mellifera bees.

Bees are important pollinators for ecosystems and agriculture; however, populations have suffered a decline that may be associated with several factors, including habitat loss, climate change, increased vulnerability to diseases and parasites and use of pesticides. The extensive use of neonicotinoids, including imidacloprid, as agricultural pesticides, leads to their persistence in the environment and accumulation in bees, pollen, nectar, and honey, thereby inducing deleterious effects. Forager honey bees face significant exposure to pesticide residues while searching for resources outside the hive, particularly systemic pesticides like imidacloprid.

Concurrent validity and test-retest reliability of VALD ForceDecks' strength, balance, and movement assessment tests.

Objectives: To evaluate the concurrent validity and test-retest reliability of common movement, strength, and balance tests using portable uniaxial dual force plates.

Design: Repeated measures cross-sectional study.

Methods: Sixteen healthy individuals participated in two testing sessions, where they performed 12 different movement, strength, and balance tests.
