Abstract

Consumption of protein in weight training when adjusted to the needs will result in perfect muscle growth and development, especially in increasing maximum strength. In fact, many Fitness Members consume protein without paying attention to the dose, so that increasing maximum strength is not realized properly. This study aims to provide high-protein supplements and high-protein foods in weight training to increase maximum muscle strength. The design used in this study is a three group pre test and post test, consisting of a group consuming high protein supplements, a group consuming a high protein diet and a control group. The population in this study are FIK UNP students, with a total sample of 39 people. The instrument used in this study is a maximum strength test (leg & Hand Dynamo Meter test). The data obtained in this study are analyzed by analysis of variance (ANOVA) with = 0.05. The results showed: (1) There was a difference in effect between the group given high protein supplements, high protein die,t and the control group, (2) The group given high protein supplements had a difference from the average of the other two groups, (3) The group given high protein supplements high-protein supplements had a difference from the average of the other two groups, (4) The high-protein diet group did not have a mean difference with the control group. The limitation in this study is that the researcher was not able to control aspects that were outside the research activities such as other high protein contamination consumed by the research food samples. The next stage, this research will look at the effects of consuming high-protein supplements on a sustainable basis on human health.

Abstract

This systematic literature review was designed to synthesize the latest research on the associations among BMI, physical activity and motor competence in children aged 3–12 years and to present the methodological map of this field. Following the PRISMA 2020 format, this review undertook a structured Scopus database search of publications from 2020 to 2026 (search conducted on 30 June 2026). Upon elimination of non-English and document-type-ineligible records (43), a total of 520 records were screened by title and abstract. Of these, 120 reports were retrieved and 111 were full-text assessed. Fifty studies were finally included in the synthesis after application of the predefined eligibility and quality (FICO) criteria. Four thematic findings were revealed. To begin with, the link between higher BMI and poorer motor competence was not only consistent, but could also be traced down to very early childhood years. Secondly, physical activity and motor competence were mutually beneficial and positively related, quite often their relationship was indirect and going through physical fitness. Thirdly, both motor-skill and multicomponent interventions brought about improvements in motor competence as well as adiposity-related outcomes, especially in children with problems of overweight or obesity. Fourthly, motor competence correlates existed on the level of individual, family and environment. Conceptually the results push forward reciprocal and developmental frameworks of motor competence; on the other hand, they give support to the idea of early, skill-centered physical-activity promotion in educational and community settings. Further studies would do well to focus on longitudinal, compositional, and intervention designs that regulate the use of motor-assessment tools in an effort to identify causal relationships and help the formulation of policies that can be implemented on a large scale.

Abstract

Sport-confidence was assessed through the 13-item Trait Sport-Confidence Inventory (TSCI), learning motivation through the 18-item Sport Motivation Scale-II (SMS-II), and basketball skill-learning outcomes through the AAHPERD Basketball Skills Test (speed spot shooting, passing, and control dribble), combined into a composite T-score. Data were studied using Pearson product-moment correlation and multiple correlation with an F-test of significance. Descriptive outcomes showed a high level of confidence (M = 48.69, SD = 8.57) and a high level of motivation (M = 50.93, SD = 6.04) mainly. Sport-confidence was not significantly linked to basketball skill outcomes when taken alone (r =.239, p =.212), and the same for learning motivation (r = -.224, p =.243). However, the two psychological variables taken together predicted a significant portion of variance in skill outcomes (R =.461, R² =.212, F(2, 26) = 3.502, p =.045), which accounted for 21.2% of the variance. These results indicate that confidence and motivation function as complementary rather than independent predictors of motor-skill learning, and that their combined psychological profile, rather than either construct alone, has substantial educational meaning. Since the sample size was quite small (only 29), we consider results from the study as preliminary evidence rather than a thorough test of the hypotheses; however, the fact that 21.2% of the joint variance was explained means that instruction in PE that deals with both confidence and motivation at the same time, rather than treating them as separate targets, could be the one that ultimately results in the greatest practical benefit when it comes to skill acquisition. A discussion of the implications for psychologically informed PE pedagogy and directions for confirmatory research with larger samples is provided.

Abstract

Kondisi fisik dan keterampilan teknis sering dianggap sebagai faktor utama yang menentukan performa atlet bela diri. Namun, penelitian terkini menunjukkan bahwa faktor psikologis, khususnya persepsi situasional dan motivasi, turut berperan penting dalam keterampilan bertanding. Penelitian ini bertujuan untuk menganalisis pengaruh langsung dan tidak langsung kecerdasan intelektual (IQ), persepsi situasional, dan motivasi terhadap keterampilan bertanding atlet remaja pencak silat. Penelitian menggunakan pendekatan kuantitatif dengan analisis jalur (path analysis). Sampel terdiri atas 20 atlet pencak silat usia 13–17 tahun yang dipilih secara purposive dari program pembinaan POPDA Kabupaten Rokan Hulu, Riau. IQ diukur menggunakan Culture Fair Intelligence Test (CFIT), sedangkan persepsi situasional dan motivasi diukur melalui kuesioner yang telah memenuhi kriteria validitas dan reliabilitas (Cronbach’s alpha = 0,901 dan 0,908). Keterampilan bertanding dinilai menggunakan rubrik observasi pertandingan yang terstandar. Hasil penelitian menunjukkan bahwa persepsi situasional berpengaruh langsung dan signifikan terhadap keterampilan bertanding (β = 0,858; p = 0,001) serta memiliki pengaruh tidak langsung melalui motivasi (β = 0,301). Motivasi juga berpengaruh langsung dan signifikan terhadap keterampilan bertanding (β = 0,540; p = 0,034). Sebaliknya, IQ tidak menunjukkan pengaruh langsung maupun tidak langsung yang signifikan terhadap keterampilan bertanding. Secara simultan, ketiga variabel prediktor menjelaskan 64,8% variasi keterampilan bertanding atlet (R² = 0,648). Temuan ini menunjukkan bahwa persepsi situasional dan motivasi merupakan prediktor yang lebih kuat dibandingkan IQ dalam menjelaskan keterampilan bertanding atlet remaja pencak silat. Oleh karena itu, pengembangan aspek psikologis perlu menjadi perhatian dalam proses seleksi dan pembinaan atlet pencak silat.

Abstract

Badminton smash accuracy is an important concern in athlete training because the smash is one of the most decisive attacking techniques for gaining points during a match. However, limited research has examined the use of fixed target and moving target training methods to improve smash performance among young athletes at PB Muda Mandiri. This study aims to analyze the effect of fixed target and moving target training methods on badminton smash performance. A quantitative approach was employed using a quasi-experimental design, involving 10 male badminton athletes selected through purposive sampling from a total population of 25 athletes at PB Muda Mandiri. Data were collected using a badminton smash performance test and analyzed through the Lilliefors normality test and t-test at a significance level of α = 0.05. The findings indicate that fixed target and moving target training methods significantly improved badminton smash performance. The average pre-test score was 12, while the average post-test score increased to 20 after the treatment. Hypothesis testing showed that t-count = 4.57 was higher than t-table = 1.833, indicating that the null hypothesis was rejected and the alternative hypothesis was accepted. The study concludes that fixed target and moving target training methods play an important role in enhancing badminton smash performance. These findings contribute to the development of badminton training methods by demonstrating the effectiveness of structured target-based exercises in improving smash accuracy. Practically, the study recommends that coaches integrate fixed target and moving target exercises into technical training programs, while future research should involve larger samples, control groups, and additional performance indicators such as smash speed, power, and match effectiveness.
