The aim of this study was to compare the effects of game design modification, the type of the goal and the number of players on the intensity of play in small-sided soccer games (SSGs) in youth elite players. Twenty young soccer players (age 13.7 ± 0.5 years, body mass 57.4 ± 7.8 kg, body height 1.67 ± 7.8 m, maximal heart rate 201.1 ± 8.2 beats/min) performed three types of SSGs (possession play (PP) vs. regular goals (RG) vs. small goals (SG)) in both four-a-side and six-a-side formats. The heart rate responses were recorded and analysed as an indicator of the intensity of play. The four-a-side format obtained higher intensity of play than six-a-side for PP (p<0.05), but not for SG and RG. SG showed higher intensity of play than RG for four-a-side (p<0.001), but not for six-a-side. PP registered higher intensity of play than RG (p<0.05), but not than SG in four-a-side, whereas in six-a-side no differences were found between the three formats. In conclusion, the modification of variables such as the number of players, the game design and the type of the goal influences the intensity of play in small-sided soccer games in youth players.

Transforming growth factor-beta 1 () and type I collagen play crucial roles in the pathogenesis of diabetic bladder disease (DBD). Moderate-intensity aerobic exercise increases antioxidant activity to help manage DBD. The aim of this study was to evaluate the effect of moderate-intensity aerobic exercise on the expression of and type I collagen in the detrusor and lamina propria of the bladder in a type 2 diabetes mellitus (T2DM) rat model.

Aim: Odontogenesis is a complex and highly regulated biological process that involves a range of molecular mechanisms. Among these, Ki67 and Cyclin D1 are crucial cell cycle regulators that play pivotal roles in controlling cell proliferation during tooth development. This study aims to provide detailed insights into the expression patterns and functional significance of Ki67 and Cyclin D1 in tooth development.

Gamma-band oscillations (GBOs) in the primary somatosensory cortex (S1) play key roles in nociceptive processing. Yet, one crucial question remains unaddressed: what neuronal mechanisms underlie nociceptive-evoked GBOs? Here, we addressed this question using a range of somatosensory stimuli (nociceptive and non-nociceptive), neural recording techniques (electroencephalography in humans and silicon probes and calcium imaging in rodents), and optogenetics (alone or simultaneously with electrophysiology in mice). We found that (1) GBOs encoded pain intensity independent of stimulus intensity in humans, (2) GBOs in S1 encoded pain intensity and were triggered by spiking of S1 interneurons, (3) parvalbumin (PV)-positive interneurons preferentially tracked pain intensity, and critically, (4) PV S1 interneurons causally modulated GBOs and pain-related behaviors for both thermal and mechanical pain.

Time perception and enjoyment of professional soccer players in different training sessions: Implications for assessment of session-RPE and training load. J Strength Cond Res 38(12): e754-e760, 2024-The purpose of this study was to investigate whether the perception of time and enjoyment levels among professional soccer players varied according to the type of training undertaken and whether this influenced the training load (TL) assessment method of session-rating of perceived exertion (sRPE).
