Overexpression of G6PD as a model of robustness
2018
Introduction Frailty is a major geriatric syndrome that has been associated to oxidative stress. The antioxidant system is largely based on the reducing power of NADPH, whose levels are mainly determined by the enzyme glucose-6-phosphate dehydrogenase (G6PD). Material and methods Using old female Tg-mice overexpressing G6PD (18 to 26 months old), we measured frailty and different muscle parameters: oxidative stress, cross-sectional area (CSA), markers regulating protein synthesis, mitochondrial dynamics, and apoptosis. Results Our results show that 18–24 months old G6PD-Tg animals performed better in the motor coordination and grip strength test than the WT. We also found lower changes in b…
Cerebellar granule-cell-specific GABAAreceptors attenuate benzodiazepine-induced ataxia: evidence from α6-subunit-deficient mice
1999
Benzodiazepine- and alcohol-induced ataxias in rodents have been proposed to be affected by the gamma-aminobutyric acid type A (GABAA) receptor alpha 6 subunit, which contributes to receptors specifically expressed in cerebellar granule cells. We have studied an alpha 6 -/- mouse line for motor performance and drug sensitivity. These mice, as a result of a specific genetic lesion, carry a precise impairment at their Golgi-granule cell synapses. On motor performance tests (rotarod, horizontal wire, pole descending, staircase and swimming tests) there were no robust baseline differences in motor function or motor learning between alpha 6 -/- and alpha 6 +/+ mice. On the rotarod test, however,…
Trajectories of motor coordination in 4–7-years-old children: A latent growth curve analysis
2014
Introduction For being able to take part in physical activities typical to the given age, children need proficiency in several motor tasks. Gross motor coordination (MC) is a basis for executing motor tasks and for learning new movement patterns. This study aimed to identify different MC trajectories in children aged 4–7-years-old. Methods Motor coordination of children ( n = 94, mean age 6.1 ± 1.3 years at baseline) was measured at 0, 6 and 12 months by KTK-test battery [1] . To identify different MC trajectories, developmental trend of the mean score of KTK was analyzed by using a latent growth curve and growth mixture analysis. Results In general, MC developed significantly over the yea…

Differences in the Motor Coordination Abilities Among Adolescent Gymnasts, Swimmers, and Ice Hockey Players
2017
AbstractPurpose. Motor coordination is proposed to be a relatively stable age-related construct, unlikely to be influenced by aligned experiential factors such as intensive sport-specific training. The purpose of the study is to investigate if there are differences in motor coordination abilities among young artistic gymnasts, swimmers, and ice hockey players.Methods. The participants of the study were 508 female and 258 male adolescents (age, M = 12.80, SD = 1.10) comprising artistic gymnasts (n = 463), swimmers (n = 70), and ice hockey players (n = 233). The KTK-test protocol was used to analyse their gross motor coordination abilities.Results. The results of the study demonstrated that g…
Motor Coordination and Global Development in Subjects with Down Syndrome: The Influence of Physical Activity
2022
Background: Many research studies have investigated motor impairments and delayed development in children with Down Syndrome (DS). However, very few studies detected these features in adults with DS. Hence, this study aimed to investigate the relationship between motor coordination and global development in subjects with DS, including adults. Furthermore, the second aim was to detect any differences in motor coordination and global development as a function of the practice of physical activity (PA) in this population. Methods: Twenty-five participants with DS (10 f, 15 m), with a chronological mean age of 27.24 years and development mean age of cognitive area of 4.93 years, were enrolled an…
Interrelationship Between Age, Gender, and Weight Status on Motor Coordination in Italian Children and Early Adolescents Aged 6–13 Years Old
2021
Although numerous evidences reported a negative correlation between motor coordination (MC) and overweight/obesity in children and adolescents, the interrelationship between age, gender, and weight status is still debatable. Hence, the aim of this cross-sectional study was to examine the association between MC and weight status according to age and gender across childhood and early adolescence in a large sample of Italian elementary and middle school students. A number of 1961 Italian school students (1,026 boys, 935 girls) was stratified in three consecutive age groups (6–7, 8–10, and 11–13 years) and four weight status categories (underweight, normal weight, overweight, and obese) accordi…
