Abstract

The problem of this study was the low smash ability of volleyball extracurricular students at SMK N 3 Payabungan Mandailing Natal, caused by inaccurate timing, improper body positioning, and weak leg muscle explosive power. This study aimed to determine the effect of leg muscle explosive power training on volleyball smash ability. This research used a pre-experimental method with a one-group pretest-posttest design. The population consisted of 30 extracurricular volleyball students, while the sample was 18 male students selected using purposive sampling. Data were collected using the Nurhasan smash test and analyzed using the t-test at a significance level of α = 0.05. The results showed that the average pretest score of smash ability was 7.06 and increased to 12.17 in the posttest. The hypothesis test showed that tcount (14.948) was greater than ttable (1.745). Therefore, it can be concluded that leg muscle explosive power training has a significant effect on improving volleyball smash ability among students of SMK N 3 Payabungan Mandailing Natal, North Sumatra.

Abstract

The problem addressed in this study was the relatively low level of forearm passing skills among students participating in the volleyball extracurricular program at SMK Negeri 2 Pariaman. This study aimed to determine the effect of repetitive training on improving the forearm passing skills of students in the volleyball extracurricular program at SMK Negeri 2 Pariaman. This study employed a quasi-experimental research design. The population consisted of all 12 students who participated in the volleyball extracurricular program at SMK Negeri 2 Pariaman. Since the population was small, a total sampling technique was used, resulting in a sample of 12 participants. The research instrument was a volleyball passing skills test. Data were analyzed using the independent mean difference test (t-test). The results showed that repetitive training had a significant effect on improving the forearm passing skills of the volleyball extracurricular students at SMK Negeri 2 Pariaman, tcount 4,38 > ttable1,79. The average forearm passing score increased by 3.1 points. These findings indicate that repetitive training is highly effective in improving forearm passing skills.

Abstract

Beach volleyball is an outdoor Olympic team sport in which heat, humidity, wind, sand, and tournament density can interact with psychological and physiological strain. This systematic literature review synthesized evidence on monitoring athlete state and performance consistency, with particular attention to psychometric, physiological/biometric, neuromuscular-load, environmental, and computational modalities. The review followed PRISMA 2020 and used a structured Scopus search of TITLE-ABS-KEY fields, identifying 144 records. Forty-eight full texts were assessed and 10 studies were retained for the core qualitative synthesis; 50 additional sources were used only for contextual comparison and were not treated as included evidence. Eligibility required beach-volleyball athlete or athlete-performance data, direct relevance to state monitoring or performance, and sufficient empirical information for extraction. Because the included studies differed substantially in design, population, exposure, timing, and outcomes, quantitative pooling was not considered methodologically appropriate and a thematic synthesis was conducted instead. The evidence indicates that session-RPE, heart-rate variability, perceived well-being, neuromuscular measures, salivary hormones, mental-fatigue measures, sleep-related indicators, and computational performance models can each capture meaningful components of athlete state, but they are usually studied in isolation. The central gap is the absence of prospectively validated systems that combine psychological, physiological, load, environmental, and computational streams to predict stable performance across tournament days. The review therefore supports a multimodal monitoring agenda while emphasizing that the proposed phenotyping framework remains a research model rather than a validated predictive system.

Abstract

Beach volleyball is a physically and psychologically demanding sport in which performance is produced by two interdependent athletes under variable environmental and competitive demands. This systematic review synthesized empirical evidence on psychological states and processes associated with competitive and technical-tactical performance in beach volleyball. Following PRISMA 2020, Scopus was searched on 21 August 2026 using predefined terms covering psychological states and processes. Of 403 records identified, 15 duplicates were removed, 388 records were screened, 98 reports were assessed in full text, and 22 studies met the eligibility criteria. Eligible studies were peer-reviewed English-language empirical investigations involving beach volleyball athletes, dyads, or teams and examining affect, anxiety, mood, mental fatigue, cognition, decision-making, motivation, coping/resilience, personality, or interpersonal processes. Thematic synthesis identified four broad clusters: affect, anxiety and mood; mental fatigue and cognition; decision-making and psychological momentum; and psychological skills, personality, and interpersonal processes. The evidence suggests that anxiety interpretation and self-confidence may be more informative than anxiety intensity alone, whereas mental fatigue and sleep restriction are consistently associated with poorer attack or perceptual-cognitive performance. Decision-making is influenced by contextual information, prior outcomes, and probability biases, while partnership quality and interpersonal regulation appear relevant to team functioning. However, the evidence base is heterogeneous, frequently cross-sectional, and based on small samples. Findings should therefore be interpreted as associations rather than universal causal effects. Future research should prioritize longitudinal, dyad-sensitive, ecologically valid, and technology-assisted designs with standardized assessment and replication.

Abstract

This comprehensive literature review, spanning from 2020 to 2026, explores the profound impact of coach communication on athletes' psychological states and performance across the three temporal phases of competition: pre-competition, in-competition, and post-competition. Utilizing the PRISMA 2020 guidelines and drawing from the Scopus database, the review meticulously analyzed 50 high-quality studies to bridge the gap between sport psychology, coaching science, and communication research. The thematic analysis revealed that verbal and non-verbal communication, precise and timely feedback, confirmation messages, and structure-giving strategies are consistently linked to enhanced athlete self-esteem, perceived capability, and drive, while effectively reducing competition-related anxiety. Moreover, overall communication quality directly influences team cohesion and objective performance outcomes. However, the effectiveness of these interactions varies depending on critical contextual factors, such as the specific stage of competition, the athlete's developmental level, the type of sport, and the strength of the coach-athlete partnership. Notably, post-competition feedback emerged as a vital component for athlete learning and burnout prevention. From a theoretical standpoint, these findings extend both general communication theory and the relation-inferred self-efficacy framework into competitive sports contexts. Practically, the review provides an evidence-based foundation for coaches to fine-tune the content and timing of their messaging according to the exact competition phase. Finally, the authors recommend that future research prioritize longitudinal study designs, cross-cultural comparisons, and standardized measurement tools to better establish causal relationships in sports communication.

Abstract

Addressing the critical healthcare challenge of non-adherence to exercise programs—where dropout rates reach up to two-thirds of participants—this systematic review synthesizes 50 peer-reviewed articles published between 2020 and 2026 from the Scopus database, following PRISMA 2020 and Tranfield et al.'s methodological frameworks. The authors identified three primary psychological drivers of patient adherence: high self-efficacy, which proved to be the single strongest predictor by increasing adherence rates by up to 33 percentage points while mediating the impact of kinesiophobia; autonomous, intrinsic motivation grounded in Self-Determination Theory, which plays a pivotal role in sustaining long-term exercise commitment among cardiac and oncology patients; and perceived barriers—including fear of movement, pain, time constraints, and insufficient provider support—which consistently predict poorer compliance and often exert a greater influence than objective disease severity. To improve clinical outcomes, the review emphasizes the necessity of routine pre-treatment screening for self-efficacy and individual barriers, alongside the implementation of autonomy-supportive rehabilitation protocols. Ultimately, the authors call for future research prioritized around longitudinal randomized controlled trials, studies focusing on underrepresented populations within low- and middle-income countries, and the integration of digital health technologies into established psychological frameworks.

Abstract

This systematic review analyzed 50 studies from the Scopus database to determine the relative contributions of psychological, technical, and physical determinants to competitive sports performance, examining how these relationships vary across sport types, competitive levels, age, and sex. Utilizing a narrative synthesis approach in accordance with PRISMA 2020 guidelines, the review found that no single domain universally dominates; rather, performance relies on an integrated, context-dependent model. Specifically, physical fitness attributes proved most prominent in team and endurance sports, technical proficiency acted as a key mediator in open-skill and precision disciplines, and psychological constructs demonstrated the highest explanatory power in high-pressure, elite individual contexts. However, the validity and generalizability of these findings are constrained by several methodological limitations identified within the literature. These include a predominance of cross-sectional designs that limit causal inference, high outcome measurement heterogeneity that precluded meta-analytic synthesis, single-reviewer screening risks, and a notable demographic bias favoring male, adult, able-bodied team-sport samples over female, youth, and Para-sport populations. To advance the field, future investigations must prioritize longitudinal, multi-domain tracking designs using standardized measurement batteries and actively incorporate underrepresented athletic populations.
