简要总结
This observational longitudinal study will examine the somatic and psychological profile of team sport athletes across seasonal training cycles. The study will include male and female athletes who play football, volleyball, or ice hockey. The planned study population consists of 300 participants, including 200 adults aged 18 to 38 years and an additional 100 adolescent athletes aged 14 to 17 years.
Participants will be assessed at two time points, before and after a transitional period in the annual training cycle, such as the off-season, holiday break, preparatory period, or competitive period. These periods are associated with changes in training load, recovery, daily routine, and lifestyle, and may therefore influence both body composition and psychological functioning. The longitudinal design will allow evaluation of changes over time and identification of factors associated with more favorable or less favorable adaptations.
The study will assess body composition and selected behavioral and psychological characteristics. Adult participants will undergo body composition assessment using bioelectrical impedance analysis and dual-energy X-ray absorptiometry (DEXA). Adolescent participants included under the approved amendment will undergo the same study procedures except for DEXA. All participants will complete standardized self-report questionnaires assessing eating behavior, physical activity, sport-related perfectionism, and body esteem.
The questionnaires used in the study include the Three-Factor Eating Questionnaire (TFEQ-13), the International Physical Activity Questionnaire (IPAQ), the sport perfectionism questionnaire, and the Body Esteem Scale. These tools will be used to examine whether eating behaviors, activity patterns outside formal training, perfectionism, and body image are associated with changes in body composition and related characteristics across different phases of the sports season.
The main goal of the study is to improve understanding of how seasonal changes in training and daily habits affect the physical and psychological characteristics of athletes. The results may help identify factors linked to beneficial or unfavorable changes in body composition and well-being, and may support the development of more individualized monitoring, nutrition, training, and psychological support strategies for athletes.
Participation in the study is voluntary. All participants, and legal guardians in the case of minors, will receive information about the study procedures, potential risks, and study aims before consent is obtained. Data will be handled confidentially and analyzed in anonymized form. Study findings are intended for scientific publication and for practical application in athlete monitoring and care.
详细描述
This study is designed to evaluate the somatic and psychological profile of athletes across seasonal training cycles in team sports. The project focuses on football, volleyball, and ice hockey players and aims to improve understanding of how seasonal changes in training load, competition demands, recovery, and daily routine are associated with changes in body composition, eating-related behaviors, physical activity patterns, perfectionism, and body image. The study is observational and longitudinal and will follow athletes across selected transitional periods of the sports season.
The rationale for the study is based on the assumption that athletic performance is influenced not only by sport-specific training but also by the interaction between physical and psychological factors. Body composition is an important component of sports readiness, as fat mass, muscle mass, and bone-related parameters may affect strength, power, speed, endurance, and movement efficiency. At the same time, athletes' eating behavior, activity outside formal training, perfectionistic tendencies, and body esteem may influence how they respond to changes in training or competition demands throughout the season.
The study population will include male and female athletes participating in organized team sports. The planned total enrollment is 300 participants. The original protocol includes 200 adult athletes aged 18 to 38 years. Under an approved amendment, the study population has been expanded to include an additional 100 adolescent athletes aged 14 to 17 years. Both healthy and injured athletes may participate, provided that they meet the study eligibility criteria and belong to football, volleyball, or ice hockey teams.
The study will be carried out at two time points, before and after a selected transitional period within the annual training cycle. Depending on the team schedule, this period may correspond to the off-season, holiday break, preparatory period, or competitive period. These phases are especially relevant because they are commonly associated with changes in training volume, training intensity, recovery, nutrition-related routines, and general lifestyle organization. Such changes may lead to measurable variation in both somatic characteristics and psychological or behavioral responses.
The main objective of the study is to assess associations between selected behavioral and psychological factors and physical characteristics in athletes across seasonal cycles. In particular, the study will examine how eating-related behaviors, physical activity, sport-related perfectionism, and body image are related to body composition and how these relationships may change over time. The study also aims to identify factors associated with more favorable or less favorable changes in somatic characteristics during periods of altered training demands.
