Introduction: Maximal oxygen volume (VO2max) is the capability of the cardiorespiratory system to deliver oxygen to muscle mitochondria, which is directly proportional to the level of stamina and is obtained from physical activity. Central obesity, which is characterized by excessive accumulation of visceral fat, can cause decreased stamina, so individuals with central obesity tend to have lower VO2max values. VO2max values can be determined by body composition, such as waist circumference, which is an indicator of central obesity. Methods: This study used an observational analytical design with a cross-sectional approach and involved 54 male respondents with high physical activity jobs who worked as building construction workers in Medan City, North Sumatra Province. Waist circumference measurements were carried out using a measuring tape, while VO2max was assessed using a 6-minute walk test. Statistical analysis was performed using the Spearman correlation test with a significance level of 0.05. Results: A total of 47 respondents (87%) had a normal waist circumference, 31 respondents (57.4%) had a fair VO2max, and 16 respondents (29.6%) had an average VO2max. The analysis showed a significant relationship between waist circumference and VO2max, with a P value of 0.000 (P<0.05) and R = -0.658. Conclusion: There is a strong and significant negative correlation between waist circumference and VO2max. This indicates that a larger waist circumference results in a lower VO2max, and a smaller waist circumference results in a higher VO2max.

Parents play a crucial role in introducing and shaping children’s gender identity from an early age. Gender identity is an essential aspect of psychological development that is closely related to the formation of behavior patterns, social attitudes, and personality development in later life. Within the family context, both fathers and mothers have complementary psychological roles in supporting children’s gender development. Mothers are generally more involved in daily caregiving and the fulfillment of children’s physical and emotional needs, while fathers tend to play a more prominent role in social interaction, play activities, and reinforcing discipline as well as adherence to prevailing cultural norms. Parenting practices, whether consciously or unconsciously applied, significantly influence how children understand gender roles, express themselves, and construct their personal identities. Therefore, appropriate, balanced, and developmentally sensitive gender identity introduction is essential to prevent role confusion and potential psychological difficulties in the future. This article aims to examine the role of parents in shaping children’s gender identity from a psychological perspective, emphasizing the importance of responsive, educative parenting that aligns with children’s developmental stages and cultural values.
