Kinematic changes in 5-m swimming start performance using the new double kick start block

Frontiers in Sports and Active Living
Enhancing start performance can substantially reduce overall race time, particularly in sprint swimming events. The aim of this study was to examine differences in angular and temporal characteristics of individual start phases over 5 m when performing ...

Interlimb Transfer of Grasp Orientation is Asymmetrical

The Scientific World Journal, 2006
One the most fundamental aspects of the human motor system is the hemispheric asymmetry seen in behavioral specialization. Hemispheric dominance can be inferred by a contralateral hand preference in grasping. Few studies have considered grasp orientation

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Fatigue development mechanisms during increased intensity exertion

Central European Journal of Sport Sciences and Medicine, 2013
During motor preparation, the attention is paid more and more frequently to the complex significance of fatigue in the case of the achieved sport outcome. The complexity of this process has not been utterly explained so far.

Are There Differences in Motor Coordination Among Spanish Primary School Students?

Journal of Functional Morphology and Kinesiology
Background: Motor coordination is a fundamental skill in childhood. Factors such as age, sex, and regular sports practice influence its development. However, there is little research that jointly analyzes the impact of these factors on the motor skills ...

A Cre‐dependent lentiviral vector for neuron subtype‐specific expression of large proteins

FEBS Letters, EarlyView.
We designed a versatile and modular lentivector comprising a Cre‐dependent switch and self‐cleaving 2A peptide and tested it for co‐expression of GFP and a 2.8 kb gene of interest (GOI) in mouse cortical parvalbumin (PV+) interneurons and midbrain dopamine (TH+) neurons.

Beta-alanine supplementation improves time to exhaustion, but not aerobic capacity, in competitive middle- and long-distance runners

Journal of the International Society of Sports Nutrition
Background Beta-alanine (βA) is a non-essential amino acid purportedly used to enhance aerobic exercise performance. While previous research indicates the benefits of βA on time to exhaustion (TTE) and aerobic capacity (VO2peak) in adults, evidence is ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Hematopoietic (stem) cells—The elixir of life?

FEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Distances Covered above and below the Anaerobic Threshold by Professional Football Players in Different Competitive Conditions

Central European Journal of Sport Sciences and Medicine, 2015
In modern endurance training information about an athlete’s performance below and above the anaerobic threshold is crucial. The aim of the present study was a comparative analysis of the total distance covered by football players in two rounds of ...
