Background: Kickboxing is a combat sport that is complex in technique, tactics, and movement structure, and requires an adequate level of motor skills as a foundation for activities during competitions. General physical fitness, defined as the effect of the externalization of motor skills, is the basis for athletic training regardless of the sport. The aim of this study was to determine the effect of modified training based on the principles of CrossFit on the development of general physical fitness in a group of kickboxers compared to a control group. Methods: The study was experimental in nature and was conducted in a group of 60 kickboxers, divided into experimental and control groups. Participants were selected by purposive sampling, and the criteria were training experience, sports skill level (minimum class 1 athletes), and consent to participate in the experiment. The intervention in the study group involved the introduction of CrossFit-based training into a conventional kickboxing training program. General and special physical fitness of the athletes were diagnosed. Results: Statistically significant differences were found in general fitness in terms of abdominal strength (p < 0.001), pull-ups (p < 0.001), dynamometric measurement of handgrip force (p < 0.001) (kg), clap push-ups (p < 0.001), standing long jump (p < 0.001), shuttle run (p < 0.001), sit-and-reach (p < 0.001), and tapping (p < 0.001). Furthermore, changes in special fitness were also demonstrated for the special kickboxing fitness test (SKFT) (p < 0.02), the total number of punches (p < 0.001), punching speed (p < 0.001), and hip turning speed (p < 0.001). There was also a correlation between characteristics of general fitness and special fitness (p < 0.001). Conclusions: The experimental training program based on the principles of CrossFit training had a positive effect on the general and special kickboxing physical fitness.

Background: Anxiety commonly affects older individuals with negative consequences on various physical and motor performances such as balance. When coupled with age-related muscular strength loss, the effects on the ability to perform daily tasks could be particularly detrimental, particularly in older women who are more susceptible to anxiety, muscular strength losses and falls. The study aimed to verify the effects of anxiety on balance performance in relation to muscular strength level in healthy older women.

Background: Understanding the dietary intake of elite adolescent athletes and its adequacy with sport nutrition recommendation is a key issue for health and player development, as well as performance and recovery. Energy availability needs to be considered to ensure optimal health and performance in young athletes. The present study aimed to quantify energy availability, energy expenditure and macronutrient intake in young male rugby union players competing at national level.

Introduction: When exercising to preferred music (PM), participants found more satisfaction and less typical exercise-related fatigue, which made it easier and more enjoyable to maintain the physical activity (PA) until the exercise goals were achieved. The purpose of this review and meta-analysis was to determine whether changes on internal training load in adult recreational athletes were modified by listening to PM and non-preferred music (NPM), during different PA.
Evidence Acquisition: A music-focused search was performed on the Google Scholar, PubMed, and Web of Science databases to identify relevant articles to this topic published after 2000 to investigate the effects of PM on psychophysiological responses to PA.

Introduction: As part of an exploratory and hypothesis-generating study, we developed the Sports Preference Questionnaire (SPOQ) to survey the athletic behavior of mentally ill children and adolescents, subjectively assessed physical fitness and perceived psychological effects of physical activity.
Methods: In a department of child and adolescent psychiatry, we classified 313 patients (6-18 years) according to their primary psychiatric diagnosis. The patients or-in the parental version of the questionnaire-their parents reported their sport preferences on the SPOQ.

Patients with generalized myasthenia gravis (MG) often show restrictive spirometry results. Although regular exercise and physical fitness are linked to better respiratory function, there is limited research assessing the effects of aerobic exercise on lung function in MG patients. The aim of this study was to analyze the effect of low-intensity aerobic exercise using a cycle ergometer on lung function parameters in MG patients.
