Background: Sarcopenia significantly affects the health and quality of life in older adults. Exercise combined with nutritional interventions is widely recognized as an effective strategy for improving sarcopenia outcomes. However, current studies rarely focus on differential effects across subpopulations with distinct demographic and health characteristics. This study aimed to explore the effects of combined exercise and nutrition interventions on sarcopenia-related outcomes, considering the variations in population characteristics. Methods: A systematic search was conducted across PubMed, Embase, the Web of Science, and Cochrane Library, covering the literature published between January 2010 and March 2025. Only randomized controlled trials (RCTs) evaluating combined exercise and nutritional interventions for sarcopenia were included. The primary outcomes were handgrip strength (HS), the skeletal muscle mass index (SMI), gait speed (GS), and the five-times sit-to-stand test (5STS). The mean differences (MD) with 95% confidence intervals (CIs) were calculated. Random-effects models were used for the meta-analysis and subgroup comparisons. Results: Fifteen RCTs involving 1258 participants in the intervention group and 1233 in the control group were included. Exercise combined with nutritional interventions significantly improved sarcopenia-related outcomes. HS improved with a pooled MD of 1.77 kg (95% CI: 0.51 to 3.03, p = 0.006); SMI increased by 0.22 kg/m² (95% CI: 0.09 to 0.35, p = 0.0007); GS improved by 0.09 m/s (95% CI: 0.04 to 0.14, p = 0.0002); and 5STS performance improved with a time reduction of −1.38 s (95% CI: −2.47 to −0.28, p = 0.01). Subgroup analyses indicated that the intervention effects varied according to age, BMI, and living environment. Conclusions: Exercise combined with nutrition is effective in improving key outcomes associated with sarcopenia in older adults. The magnitude of these effects differed across population subgroups, underscoring the importance of tailoring interventions to specific demographic and health profiles.

This study aimed to compare the effects of two 12-week training intervention experimental ball games combined with standard behavioral rehabilitation against a control group solely utilizing standard behavioral rehabilitation on social communication impairments (SCI) in preschool children with Autism Spectrum Disorder (ASD). A multi-arm controlled study design was implemented, involving 41 children diagnosed with ASD (mean age: 4.99 ± 0.76 years). 41 participants were randomized assigned to two experimental groups and a control group, The experimental group carried out ball combination training program group (BCTP) and mini-basketball training program group (MBTP) on the basis of routine behavioral rehabilitation, which underwent 12-week training interventions 5 times a week. The control group (n = 14) received only standard behavioral rehabilitation. Evaluations were conducted before and after interventions using the Social Responsiveness Scale, Second Edition (SRS-2). The results suggest that both 12-week interventions, BCTP, and MBTP, led to significant improvements in social communication impairment among children with ASD (p < 0.05). Despite enhancing the overall scores on the SRS-2, these interventions displayed varying impacts across different sub-dimensions. BCTP primarily exhibited significant enhancements in social awareness and behavior pattern (p < 0.05), whereas MBTP significantly improved social cognition and social communication (p < 0.05). Both interventions showed slight improvements in social motivation. The utilization of recreational ball games has showed to be effective in decreasing the impairment levels of children with ASD, while the control group experienced a worsening of outcomes. This suggests that irrespective of the specific ball game strategy employed, both can be employed on a weekly basis to complement standard behavioral rehabilitation and enhance the ability to improve the quality of life for children diagnosed with ASD. The trial is retrospectively registered on the Chinese Clinical Trial Registry (ChiCTR1900024973;August 5, 2019).

This study investigated perceived exertion (RPE) differences among soccer players at two competitive levels - Tier 2 (trained) and Tier 3 (highly trained) - during small-sided games (SSGs) and high-intensity interval training (HIIT), while controlling for internal physiological load using percentage of heart rate reserve (%HRreserve). Seventy-seven male university players from the China University Football Association participated (Tier 2: n = 37; Tier 3: n = 40). Each player underwent a fitness assessment to determine HRmax and HRrest, followed by four randomized training sessions: 5v5 SSGs, 1v1 SSGs, long HIIT, and short HIIT. Heart rate was continuously monitored, and players reported RPE using the Borg CR10 scale immediately post-session. A linear mixed-effects model was used, with competitive level and training format as fixed effects, and %HRreserve included as a statistical covariate. The analysis revealed a significant interaction between training format and competitive level (F(3, 224.761) = 3.20, p = .024), indicating that the influence of training format on RPE varied by competitive level. A significant main effect of training format was also found (F(3, 234.484) = 11.24, p < .001). Specifically, Tier 3 players reported higher RPE during short HIIT than Tier 2 players (p = .002). Both groups reported lower RPE during 5v5 SSGs compared to 1v1 SSGs and HIIT formats (all p ≤ .003). These findings show that training format influences RPE in a format- and tier-specific manner, even when accounting for internal physiological load. For coaches and sports scientists, larger-sided SSGs may be useful to reduce perceived exertion while maintaining cardiovascular demand. Future research should include elite players and assess psychological and physiological mediators to better understand the complex drivers of perceived effort.

Background: Eating behavior problems significantly affect the physical health and quality of life of children with autism spectrum disorder and intellectual disabilities (co-occurring ASD/ID). This study aimed to evaluate the effects of a 12-week Ball Combination Training Program (BCTP), continuous theta burst stimulation (cTBS), and an intervention combining both (in the CIG) on the eating behaviors of children with co-occurring ASD/ID. Methods: A total of 48 participants were assigned into one of four groups: the BCTP (n = 13), cTBS (n = 12), the CIG (n = 11), and a control group (n = 12). The intervention groups received their respective treatments in addition to the routine institutional rehabilitation, whereas the control group only received the standard institutional rehabilitation. The intervention outcomes were assessed using the parent-reported Children’s Eating Behavior Questionnaire (CEBQ). Results: The results indicated that all three intervention methods led to improvements in their eating behavior after 12 weeks. Specifically, the BCTP group and the CIG demonstrated significantly reduced Food Fussiness behavior, while the children’s Enjoyment of Food was markedly enhanced in the cTBS group and the CIG. Furthermore, the CIG experienced a particularly notable effect in terms of the improvement in the Satiety Responsiveness dimension of their eating behavior. Among the three approaches, the CIG demonstrated a clear advantage over the single interventions in terms of both the breadth and magnitude of its improvements. Conclusions: This study confirmed the effectiveness of these three intervention strategies in addressing dietary behavior problems among children with co-occurring ASD/ID. Future research should focus on exploring the combined intervention approach further, particularly its potential synergy, while delving deeper into the neural mechanisms underlying these behavioral improvements.

Background: Exercise is increasingly recognized as a non-pharmacological strategy for cognitive aging; however, comparative evidence across modalities, phenotypes, and doses is limited. Methods: We conducted a Bayesian network meta-analysis of 38 randomized controlled trials ( N = 4,047; 88 arms). The interventions included aerobic, resistance, multimodal, and other exercise formats compared with non-exercise controls. The primary outcome was global cognition. Analyses were stratified by age (< 70 vs. ≥70 years) and phenotype (healthy vs. pre-sarcopenic). Dose–response relationships were modeled using the weekly volume (MET·min/week). Results: Aerobic (standardized mean difference [SMD] 0.58, 95% CI 0.33–0.83), resistance (0.62, 0.35–0.88), and multimodal programs (0.68, 0.40–0.95) significantly improved cognition compared to the control, with smaller effect sizes. Healthy older adults benefited most from aerobic (0.88, 0.55–1.20) and resistance training (0.80, 0.42–1.19), whereas multimodal programs were most effective for pre-sarcopenia (0.60, 0.29–0.90). Dose–response analysis showed clinically meaningful benefits from ~ 600 MET·min/week, with optimal effects between 700 and 1,200 MET·min/week. Higher volumes conferred no consistent additional gains in pre-sarcopenia. Conclusions: Exercise is a scalable, safe, and clinically effective approach for preserving late-life cognition. For healthy older adults, aerobic or resistance training at ≥ 600 MET·min/week is recommended; for pre-sarcopenic individuals, multimodal programs at approximately 700–800 MET·min/week offer the best balance of efficacy and sustainability. These findings provide actionable targets for clinicians and policymakers, advancing precision exercise prescriptions for cognitive health in aging populations.
