Research on the acute physiological response to a padel match is limited. The present study aimed to: (a) evaluate neuromuscular, urinary, and hematological responses after simulated padel competition (SC) and (b) analyze possible gender differences. In this study, 28 high-level padel players participated (men = 13, age = 26.83 ± 6.57 years; women = 15, age = 30.07 ± 4.36 years). The following parameters were analyzed before and after SC: neuromuscular (hand grip strength, squat jump (SJ), countermovement jump (CMJ), and Abalakov jump (ABK)), hematological (red blood cells, hemoglobin, and hematocrit), and urinary (pH, specific gravity, microalbuminuria, and red blood cells). Significant gender differences were found in neuromuscular and hematological responses, with men obtaining higher values (p < 0.05). For the SC influence, changes were noted in ABK and microalbuminuria (p < 0.05). The percentages of change in hand grip strength, SJ (height and watts), CMJ (height), and ABK (height) were higher for men than women (p < 0.05). SC negatively influenced the neuromuscular parameters to a greater extent in women. Our results could be related to gender differences in game actions, the temporal structure, and anthropometric and physiological characteristics. Game dynamics and a different organic response between male and female padel playing were confirmed.

Haematological and biochemical parameters have not yet been analysed in professional padel players. The aim of this study was to determine the basal values of these parameters and to observe the effect of a simulated competition on them, including gender-related differences. A total of 14 male professional players (age: 28.2 ± 7.9 years), and 16 female professional players (age: 29.7 ± 3.7 years) participated in this study. Players were allowed to hydrate ad libitum during the matches. Haematological and biochemical values were obtained before and after a simulated competitive padel match. The men’s group showed higher baseline values in red blood cells, haematocrit, haemoglobin, urea, creatinine, uric acid, albumin, glutamic oxaloacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), lactate dehydrogenase (LDH) and creatine kinase (CK) (p < 0.01) than the women’s group. Attending to match effect, significant differences were obtained in urea, creatinine, CK and glucose (p < 0.05). Finally, the group x match interaction revealed significant differences in serum concentrations of sodium and chloride (p < 0.05). In conclusion, high-level padel matches provoke several changes in biochemical parameters related to muscle damage and protein catabolism. Recovery and fluid intake strategies could be added regarding gender. The results obtained could be due to the differences in the intensity and volume of the simulated competition.

Racket sports are very popular not only in professional sports but also among recreational players. As a result, their impact on the field of education has grown significantly in recent years. Table tennis (TT) offers significant advantages in terms of skill acquisition and health improvement. Nevertheless, its application within physical education (PE) curricula remains undetermined. The aim of this systematic review was to analyze the use of TT as educational content in the subject of PE in primary school. The PRISMA 2020 methodology was used to conduct the systematic review. Six databases (ERIC, Pubmed, ScienceDirect, Scopus, Sport Discus, and Web of Science) were used during the search process. The search cutoff date was December 31, 2024. After applying the eligibility criteria, 3595 articles were found. Only seven studies were selected for the final analysis and the data included 1526 students from primary school. The results indicate that TT is rarely used in primary education during PE classes. Research indicates interest among teachers and students in playing it during PE. Furthermore, due to the benefits, motivation, and interest this sport generates, educational experiences have been developed, such as roundtable discussions, table top tennis, balloon TT, and TT triathlon. A lack of materials, facilities, and teacher training for teaching this sport is notable. The teaching experiences analyzed in this review confirm that TT is a highly versatile and interesting sport as a subject matter in school PE. The use of TT allows for innovative, comprehensive, and inclusive PE, thanks to the sport’s multiple possibilities. Given its adaptability and low entry barrier, TT could serve as an effective tool for increasing children’s physical activity levels, improving motor skills, and fostering social–emotional development. However further research is needed to quantify its impact on health outcomes such as cardiovascular fitness or obesity prevention.

Ultra-trail events (UTs) pose significant challenges to maintaining hydration and electrolyte balance, with risks of dehydration (DH), overhydration (OH), exercise-associated hyponatremia (EAH), and exertional rhabdomyolysis (ER). This study examined the effects of ad libitum (ADL) hydration on hydration status and muscle damage during a nine-stage UT (635 km, 40,586 m elevation gain). Four highly trained male athletes participated. Hydration was assessed via body weight loss (BWL), urine specific gravity (Usg), and serum sodium ([Na+]), while muscle damage markers included creatine kinase (CK), lactate dehydrogenase (LDH), and calcium (Ca), and liver damage biomarkers included aspartate aminotransferase (AST) and alanine aminotransferase (ALT). Our results showed no cases of EAH or hypernatremia ([Na+] > 145 mmol·L−1), with serum [Na+] maintained above 135 mmol·L−1. BWL exceeded the 2% DH threshold in early stages (p = 0.029), and Usg remained elevated (>1.020 g·mL−1). LDH and CK significantly increased at all stages (p < 0.05), persisting for 48 h post-event. Correlations showed BWL aggravated muscle damage (r = 0.47 with CK) and hypocalcemia (r = −0.68 with Ca). Elevation gain/loss amplified fluid loss and muscle injury. While ADL hydration mitigated EAH, it did not fully address DH or muscle damage. Personalized hydration and recovery protocols are crucial to optimizing performance and health in UT events.

Background: Suryanamaskar (Sun Salutation) is a dynamic sequence of yoga that incorporates movement, breath and mindfulness, and is known for its many potential multidimensional health benefits. Despite the increasing volume of research, a comprehensive and domain-specific synthesis examining the multidimensional effects of Suryanamaskar and yoga-based interventions incorporating Suryanamaskar remains limited. Hence, the present study was designed to systematically review and synthesize the existing evidence related to the effects of Suryanamaskar and yoga-based interventions using Suryanamaskar sequence on various populations and outcome domains. Methods: This systematic review was conducted in accordance with the PRISMA 2020 statement and Cochrane Handbook recommendations. Literature searches were performed in PubMed, Scopus, Web of Science, and Google Scholar from database inception to 31 December 2025. Studies involving human participants and Suryanamaskar-based interventions reporting measurable physical, physiological, or psychological outcomes were included. Fourteen studies met the eligibility criteria. Study characteristics, intervention protocols, and outcome measures were extracted. Risk of bias was assessed using RoB 2 for randomized studies and ROBINS-I for non-randomized studies. Due to substantial heterogeneity, findings were synthesized narratively. Results: A total of 14 studies met the inclusion criteria. Overall, Suryanamaskar and yoga-based interventions incorporating Suryanamaskar were associated with improvements in physical fitness, physiological health, psychological well-being, and body composition across diverse populations. Most included studies reported favourable changes in physical fitness, physiological, psychological, and body-composition outcomes; however, the magnitude and consistency of findings varied substantially across study designs, participant populations, intervention protocols, and outcome measures. Conclusions: Promising but heterogeneous evidence suggests that Suryanamaskar and yoga-based interventions incorporating Suryanamaskar may contribute to improvements in physical fitness, physiological function, psychological well-being, and body composition across diverse populations. However, these findings should be interpreted with caution because of variability in study designs, intervention protocols, participant characteristics, and risk of bias. Although Suryanamaskar appears to be a practical, low-cost, and holistic intervention with potential applications in educational, sports, and health-promotion settings, further high-quality randomized controlled trials with standardized protocols and larger sample sizes are required to strengthen the evidence base.

Objective: Low-Load Blood Flow Restriction Training (LLBFRT) is an emerging approach in order to increase muscle endurance and muscle volume, as well as decrease pain in the early rehabilitation phase. The purpose of this review was to analyze the published literature on the effects of this intervention on musculoskeletal postsurgical rehabilitation. Methods: Six electronic databases (Cochrane Library, PubMed, SPORTDiscus, SCOPUS, CINAHL, and Web of Science) were searched from 2004 to 2024. Articles including adults who underwent any type of musculoskeletal surgery were screened. The Risk of Bias and Quality of Evidence were assessed using the Cochrane Risk-of-Bias Tool (RoB 2) and GRADE-CERQual scale. A meta-analysis was performed on the identified studies using RevMan version 5.4. The analysis model was synthesized as a random effects model, and the standard mean difference (SMD) was used as the effect measure. Results: Thirteen articles fulfilled the selection criteria and were included in this review. Muscle strength, muscle volume, and perceived pain had positive results in almost all studies; however, the meta-analysis reported a lack of overall effect in favor of LLLBFRT vs. control interventions in both lower and upper limb evaluations. Conclusions: Although some studies indicate positive effects of LLBFRT on strength, muscle size, and pain perception in operated lower and upper limbs, these results must be interpreted carefully since the overall effects are unclear. Nonetheless, the selected studies did not report discomfort claims; therefore, the LLBFRT could be a safe recovery strategy to use when rehabilitation programs need to gain variety.
