Abstract:

The purpose of the roundtable is to present the biological determinants which influence weightlifting performance as we as the training and nutrition strategies to enhance weightlifting performance especially prior to competitions. In weightlifting, lean mass in both male and female athletes seems to contribute to performance. Studies have shown that the percentage of muscle fiber type IIa distribution prevails over the total muscle fiber distribution while a significant connection exists between percentage muscle fiber IIa and weightlifting performance. Moreover, weightlifters are known for their high neuromuscular activation of the protagonist muscles which lead to a higher recruitment of type II motor units and as a consequence to greater power production. From a practical perspective, long-term training enhances the biological determinants, leading to significant increases in strength, power and performance. In addition, performance is enhanced prior to major competitions with tapering. Tapering in weightlifting includes the reduction of both training intensity and volume, especially during the final week before the competition. For a successful competition it is suggested a tapering period of 8.0±4.4 days, with the last high intensity training performed 5.9±2.3 days prior to competition while it is recommended 1.5±0.6 days abstinence from training. However, research evidence suggests that a priming training session with low volume and moderate to high intensity 6-24 hours prior to competition may significantly enhance performance. Furthermore, nutrition in youth or adult athletes is a foundation factor for enhancing performance. Adequate macronutrient intake is crucial for muscle mass development, neuromuscular performance, and recovery from training stress. Additionally, adopting proper nutritional habits and strategies can contribute to better body mass management and enhanced performance during the competitive season.

Abstract:

This round table aims to present Taekwondo as an integrated developmental and performance model, linking its contribution to brain maturation and psychosomatic development in childhood with contemporary scientific approaches to combat performance assessment.The contribution of Taekwondo to functional brain and central nervous system maturation is examined through its complex motor and cognitive environment. The wide repertoire of techniques, tactical decisions, combinational movements, traditional and competitive practice forms, as well as the use of specialized games, create conditions of heightened neuromuscular and cognitive stimulation. Core cognitive functions—including attention, concentration, memory, perception, rapid decision-making, and the simultaneous processing of multiple external stimuli—are systematically enhanced, contributing significantly to the child’s overall developmental trajectory. Furthermore, contemporary research findings on objective combat performance evaluation are presented. The frequency–speed kick test, muscular power, rate of force development, vertical and horizontal jump performance, and body composition emerge as key indicators of competitive level and athletic performance. Particular emphasis is placed on long-term athlete development planning and the avoidance of early specialization, aiming to ensure psychosomatic safety and sustainable athletic progression. The scientific framework is complemented by the experiential contribution of Olympic Gold Medalist Michalis Mouroutsos, highlighting the link between a properly structured developmental foundation and high-level competitive success.

Abstract:

The roundtable discussion on the prevention and management of injuries in power sports will present epidemiological data on injuries that occur in power sports such as weightlifting and wrestling. In addition, the principles of designing rehabilitation programs after injuries that occur in powerlifting will be analyzed. For the sport of wrestling, based on the epidemiological data of the injuries that have been recorded, the factors that must be taken into account for the effective design of an injury prevention program will be mentioned. Nutrition plays an important role in the management of power sports athletes. The nutritional approach of weightlifting athletes will be analyzed, which aims to optimize performance, strength and recovery after training. Energy needs are increased due to intense training, therefore adequate calorie intake and proper distribution of macronutrients are required. Furthermore, strategic nutrition planning is often a key element in the prevention and recovery of injuries, which often occur due to high loads and high intensities.

From Compliance to Adherence: The Interdisciplinary Management of Obesity through the Biopsychosocial Model of Health

Thaleia Bellali, Professor, Department of Nursing, International Hellenic University / Adjunct Professor, Department of Health Sciences, School of Sciences, European University Cyprus

Abstract:

In the present roundtable, the modern scientific developments in the field of bariatric surgery will be discussed, which constitutes the treatment of choice for patients with morbid obesity. Based on recent scientific data, maintaining a good postoperative outcome requires interdisciplinary follow-up of the patient after surgery in order to sustain weight loss and reduce the risk of lean body mass loss. The dietary guidelines provided to patients, as well as the exercise instructions and protocols applied both pre- and post-operatively, will be presented and discussed.  Particular emphasis is also placed on the distinction between compliance and adherence to therapeutic recommendations, as adherence does not involve the passive acceptance of instructions but rather the active participation of the individual with obesity in decision-making, the co-creation of achievable goals, and the joint agreement on an intervention plan that reflects their needs, capacities, and priorities. From this perspective, the therapeutic alliance is substantially strengthened, creating more favorable conditions for the long-term maintenance of lifestyle changes. In this light, it is argued that an interdisciplinary, rather than merely multidisciplinary team, constitutes the most appropriate and effective approach for the management of morbid obesity.

Abstract:

Physical inactivity, sedentary behavior, and excessive internet use are global problems, and the initiatives undertaken by international and national organizations are insufficient to effectively address them. These issues pose a serious threat to public health, as both children and adults fail to meet the recommended guidelines for physical activity. It is estimated that health risks affecting nearly 500 million people between 2020 and 2030 could be mitigated through increased physical activity. The global economic cost of health problems related to physical inactivity is estimated at approximately 47.6 billion US dollars annually. This section will present the necessary initiatives that scientific organizations, such as universities, should undertake at the national level, based on the guidelines of the World Health Organization. Examples will be presented for the design of exercise-for-health programs across all age groups, as well as for Physical Education in schools, based on goal setting theory and other psychological strategies. The session will conclude with the adaptation of these examples to competitive sport. Psychological strategies, as planning tools, can be utilized both in combating physical inactivity and sedentary lifestyles and in improving quality of life and maximizing performance. At the same time, competitive sport can inspire the general population to engage more in physical activity, while increased population participation can, in turn, enhance the number of individuals involved in competitive sport.
