Background: Exercise-induced stressors activate leukocyte HSPA1A and HSPB1 gene transcripts. However it is not clear how plyometric training affects the expression of these genes in basketball players under plyometric exercise. Therefore, the aim of this study was to investigate the changes in leukocyte HSPA1A and HSPB1 mRNA, in male basketball players after plyometric training. Material/Methods: Twelve male college basketball players (age 22.1 ±2.96 years) took part in this study. Peripheral blood (2.0 ml) was collected from the ulnar vein of each participant before and after a plyometric exercise to assess HSPA1A and HSPB1 mRNA relative expression of leukocyte via quantitative reverse transcription polymerase chain reaction. Results: A significant increment of leukocyte HSPA1A mRNA expression (Qt from 1.67 ±0.93 to 3.17 ±0.97, p = 0.003) after plyometric exercise was found. However, there was no significant change in leukocyte HSPB1 mRNA expression, indicating the high stability of this gene during exercises. Conclusions: HSPA1A mRNA was found to be a very sensitive indicator and could be used to assess physiological adaptation to a physical load and time requirements for complete recovery in basketball players.

Background: There is no literature regarding joint mobility in children of the Central and Eastern Europe. Studies describing clinical characteristics and functional outcomes are still needed. The aim of this study was to assess the prevalence of generalised joint hypermobility (GJH) in the group of school-aged children from Vilnius, the capital city of Lithuania, in relation to different cut-off values of the Beighton score (BS), and to identify possible patients with joint hypermobility syndrome. Materials and methods: The representative sample of this study was calculated to be 760 subjects. A total of 778 children from different schools were screened for the mobility of joints. The medical examination included an assessment of joints’ hypermobility according to the BS. The presence of specific signs (marfanoid habitus, antimongoloid slant and drooping eyelids) was assessed additionally. Parents of all involved children were asked to answer the questions developed based on the Brighton criteria regarding the medical history of children. Results: The prevalence of GJH in school-aged children from Vilnius, depending on the BS cut-off value, was 19.2% (BS ≥ 4), 9.5% (BS ≥ 5) or 5.7% (BS ≥ 6). The increased range of mobility was most frequently detected in thumbs of school-aged children. The frequency of hyperextension > 10° in knees was 7- to 8-fold lower than the frequency of hyperextension > 10° in a passive opposition of the thumb. The evaluation results were similar on the left and right sides in 87.4% cases of thumb opposition, 90.1% cases of hyperextension of 5th finger, 87.9% cases of elbow manoeuvres, and 94.8% attempts to hyperextend knee. Conclusions: The prevalence of GJH in school-aged children from Vilnius depends on the BS cut-off value and ranges from 5.7% to 19.2%. (Folia Morphol 2016; 75, 1: 48–52)
