Acute exercise induces comparable mitochondrial biogenesis and vascular angiogenesis molecular regulators in the diabetic and non-diabetic rat myocardium
type: item
description: Background: The diabetic heart is associated with mitochondrial and microvascular dysfunctions along with impaired downstream co-activators. These functions may improve with long-term exercise training. However, it is unknown how they respond to acute exercise in the diabetic compared to the non-diabetic heart. Objective: Therefore, we aimed to evaluate and compare the acute molecular responses of mitochondrial biogenesis and angiogenic and anti-angiogenic factors to a single exercise session between the diabetic and non-diabetic heart. Methods: Male Sprague-Dawley rats were assigned into one of four groups: 1- non-diabetic sedentary control (CS); 2- Diabetic exercise (DIEX); 3- Diabetic sedentary (DIS); and 4- non-diabetic exercise (CEX) groups. Left ventricles were obtained 6 – 7 weeks following diabetes induction and following a 60-min of treadmill running from CEX and DIEX. Results: Vascular endothelial growth factor and hypoxia-inducible factor 1α mRNA was not different among all groups. Thrombospondin-1 mRNA was not different in CEX and DIEX and was greater in both groups than CS and DIS (P < 0.005). Peroxisome proliferator-activated receptor (PPAR)-γ coactivator (PGC-1α) expression was not different in CEX and DIEX (P = 0.4). PGC-1α expression was lower in CS compared to all groups (P < 0.001 for CEX and DIEX, and P = 0.01 for DIS vs. CS) (Malondialdehyde was not different in all groups. Conclusion: All the above molecular responses to acute exercise were similar in the diabetic and non-diabetic hearts. This may suggest that the diabetic heart may similarly benefit from exercise in terms of mitochondrial biogenic and vascular angiogenic functions as the non-diabetic heart. Future studies should investigate the long-term training responses.

type: item
description: Objectives: This study aimed to explore the discriminative capacity of the Tennis-specific Incremental Aerobic Test (TSIAT) in differentiating between international level tennis players (IP) and regional level tennis players (RP), scrutinize the absolute and relative inter-session reliabilities of TSIAT, and assess the sensitivity and the Minimal Detectable Change (MDC) of TSIAT. Methods: A cohort-based repeated measures study design was used. Twenty-four male tennis players (age: 15.91±3.09 years, body-height: 1.68±0.20 m; body-mass: 67.45±16.06 Kg; body-mass-index: 20.96±1.97 kg·m-2) participated. TSIAT distance, peak heart rate (HRpeak), and blood lactate concentration ([La]) were measured across two sessions. Inter-session reliability, sensitivity, and minimal detectable change (MDC95) of TSIAT were assessed. Additionally, discriminant ability was evaluated by comparing TSIAT indices between international-level (IP) and regional-level (RP) players. Results: The TSIAT showed excellent reliability (ICC[3,1]=0.95 and SEM%=1.81) and satisfactory sensitivity (SWC%=1.22). The MDC95 for the distance index was small (<5.02%). IP achieved significantly (p<0.05) greater distances (d=1.63 [large]), HRpeak (d=1.18 [moderate]), and [La] (d=2.51 [large]) compared to RP. The TSIAT demonstrated “very good” discriminant ability between IP and RP groups, with an area under the ROC curve of 0.89. Conclusion: Considering the “excellent” inter-session reliability, “satisfactory” sensitivity and “very good” discriminate athletes by different performance levels, the TSIAT may serve as a trusted tennis-specific incremental aerobic test.

The Impact of Redundancy and Video Control on Tactical Learning in Basketball within the Context of Physical Education
type: item
description: This study examines the impact of redundancy and rhythm control in video on the development of tactical knowledge in basketball among 15-16-year-old learners. Participants were exposed to four conditions: "Audio without control" format (N = 20), redundant "Audio + Text without control" format (N = 20), "Audio with control" format (N = 20), and redundant "Audio + Text with control" format (N = 20). Results revealed that students achieved higher comprehension and transfer scores in the two conditions where the video was controlled. Additionally, performance demonstrated a negative impact of redundancy on learning. However, these negative effects dissipated, even reversed, in learner-controlled video conditions, accompanied by improvements in performance. Consequently, processing difficulties induced by redundancy were mitigated by pause intervals, enabling a focus solely on written content and facilitating memorization. Thus, to attenuate the negative effect of redundancy, it would be appropriate to present textual support after oral presentation and demonstration of tactical actions during video-based learning in Physical Education.

description: Background: In elite youth soccer, the extent to which anthropometric and physical fitness parameters vary according to playing positions remains unclear. Identifying and quantifying these differences is crucial for informing targeted training interventions. Objectives: We aimed to investigate the evolution anthropometric and physical profiles in Tunisian elite youth soccer players during one season, and to analyze differences between players according to their playing position. Methods: Sixty-two subjects (15.3±0.2 years, 69.4±6.4 kg, 176.9±4.8 cm) playing for the top four professional football clubs in Tunisia took part in the study. They were divided into five groups according to their playing position: goalkeepers (n=10), fullbacks (n=14), central defenders (n=11), midfielders (n=15) and forwards (n=12). Various anthropometric measurements, fitness tests assessing aerobic and anaerobic performance were performed at two times (T): T1 (3 weeks after the beginning of the preparation period), and T2 (end of the competitive period). Results: Football players across all positions exhibited significant anthropometric growth, particularly in height, with increases from small to moderate (p < 0.001; effect size (ES) = 0.30 to 0.57). Weight changes were non-significant (p = 0.01 to 0.14; ES = 0.01 to 0.14), while fat mass reductions across positions were slightly more pronounced (p = 0.05 to 0.25; ES = 0.09 to 0.25). Performance metrics revealed substantial improvements, particularly in the 5-Jump Test, where forwards excelled (p < 0.001; ES = 1.07), and in sprinting events, where consistent progress was noted across all positions (p < 0.001; ES = 0.16 to 0.33). The Yo-Yo Intermittent Recovery Test exhibited significant enhancements, again with forwards achieving the greatest gains (p < 0.001; ES = 3.01). Conclusion: The study emphasizes the need for position-specific training in youth football, highlighting how physical and anthropometric characteristics vary by playing …

The relationship between nomophobia and psychological distress in Tunisian students: The moderating effect of physical activity
type: item
description: Background: Due to their stage of life and the daily stressors they encounter, students are particularly susceptible to both behavioral and psychological issues. Our study was designed with two objectives in mind: (1) to explore the potential mitigating effect of physical activity on the relationship between nomophobia and distress in students; and (2) to evaluate the reliability and validity of the Arabic version of the Depression, Anxiety, and Stress Scales (DASS-12). Methods: A cross-sectional analysis was undertaken with a sample of Tunisian students who regularly use smartphones (N=533, 64.6% female, mean age 25.03±6.55 years). Results: The exploratory and confirmatory factor analyses pointed to the DASS-12 as a secondary 3-factor scale. The internal consistency of the scale, as measured by Cronbach’s alphas, was 0.98 for stress, 0.90 for anxiety, and 0.84 for depression. The results of the measurement model supported the suitability and reliability of all the DASS-12 items in capturing the underlying constructs. Structural model analysis revealed positive correlations between physical activity and nomophobia with stress, anxiety, and depression. Moreover, physical activity was found to moderate the relationship between nomophobia and two elements of distress: stress and anxiety. Conclusion: The findings of this study open up novel intervention strategies for students grappling with nomophobia. In particular, the results suggest that promoting physical activity might serve as a coping strategy to counteract the impacts of nomophobia on stress and anxiety symptoms in students.
