Good nutritional knowledge can help individuals to consume macronutrient intake in accordance with the body's needs, so that nutritional status can be adequately met. A cross-sectional study design and quantitative research methodology are employed. The study's sample consisted of twenty people who were chosen by purposive sampling. The Spearman rank correlation test was applied in both univariate and bivariate analyses. The results showed that most individuals' nutritional status was normal status (55%). Based on the Spearman rank test, no significant association was identified between nutritional knowledge (p=0.206), protein consumption (p=0.762), and carbohydrate consumption (p=0.772) with nutritional status. Nevertheless, fat consumption (p=0.049) showed a significant link with nutritional status. The results of this research suggest that nutritional status does not correlate with nutritional awareness, protein intake, or carbohydrate intake. However, fat intake is associated with nutritional status. It is intended that this study will inspire participants to practice mindfulness of their macronutrient intake. Coaches are also expected to provide guidance to UNESA volleyball club members to be more discerning in selecting foods for consumption

Mood or mood is an important part of a person's psychological well-being. Several studies show that physical exercise can positively influence mood. One of the factors that influences an athlete's mental and emotional readiness is mood. Mood Profile for Weightlifting athletes is an important factor that needs to be analyzed. This research aimed to determine the relationship between athletes' moods and the success rate of snatches in weightlifting athletes at PABSI Jatim Surabaya before PORPROV 2025. This qualitative research used mixed methods. Mixed methods is a research approach that combines or associates qualitative and quantitative forms. A research method that uses qualitative data and is described descriptively. The Total Sample Method is a sampling method with the number of samples equal to the population. The sample was taken using total sampling because the population was less than 100 and the entire population was used as the research sample (Masturoh & Anggita, 2018). The sample that can be used is the population sample taken from Provincial Weightlifting athletes (aged 13 - 23 years) totaling 8 people and is only limited so that they can be used as one training group by filling in a mood profile questionnaire and recording the snatch technique. Of the 8 respondents who took the snatch test, all appeared confident. However, when holding and doing the snatch, there is a feeling of doubt and anxiety about whether or not you can accept the weight of the snatch if it is already above. However, after doing the snatch test, he also felt happy by releasing endorphins in his body. The results of the before and after research show that the "Medium" category with the highest percentage is the anger indicator (AMR) of 71.43% and 42.86%, and the confused mood indicator (SSB) of 53.57% and 71%. Indicators with moderate percentages include full energy indicators (PNT) of 85.71% and 75%, self-assessment (PDR) of 80.36% and 80%, and depression (DPS) of 44.64% and 63%. The percentage of fatigue indicators (KLH) was 53.57% and 42.85% and tension indicators (KTG) were 57.14% and 50%. The conclusion of the research on the analysis of the relationship between athlete's mood and the success rate of snatches in weightlifting athletes at PABSI East Java, Surabaya is in the "Medium" condition. Negative mood conditions in the "Medium" category such as fatigue, anger, tension, confusion, and depression indicate that athletes are not feeling stressed mentally and physically. Meanwhile, positive mood conditions in the "Medium" category make athletes have a good mood, such as being full of energy and self-confidence. This is possible because the training portion is good and the conditions leading to PORPROV 2025 are still quite long. So there are still many athletes who experience good mood conditions so the presence of this athlete's mood also supports the athlete's successful performance both during training and during competitions.
