Healty Volunteers

The goal of this trial is to learn if listening daily to online hypnosis exercises helps to improve mental health and self-esteem in primary school children. In the future we also hope to see if it can prevent feelings of depession or anxiety when these children have become teenagers. The main questions it aims to answer are: 1. can daily listening to these exercsies improve self-esteem, resilience and mental health of children 10-11 years compared to children who do not listen to these exercises? 2. can listening to these exercsies prevent future metal health problems like feelings of depression or anxiety. Researchers will compare a group of children (10-11 years) who will listen daily to the exercises for 2 months with a group who will do that 6 months later. Participants will: Listen daily to a hypnosis exercise of maximum 15 minutes. Fill out questionnaires on self-esteem, resilience and mental health before during and after the study.

This study aims to investigate the effects of an 8-week structured land-based exercise program on hiking endurance, core endurance, muscle activation, balance, and motor competence in young sailors. The intervention will be applied in addition to a standard hiking bench training, which simulates the physically demanding "hiking" maneuver used in sailing. A total of 26 adolescent athletes, aged 12 to 18 years, will be randomly assigned to two groups: one receiving hiking bench training only, and the other receiving hiking bench training combined with structured strength, flexibility, balance, and dynamic warm-up exercises. Evaluations will include endurance testings, electromyography (EMG) analysis of muscle activity, balance tests, and motor coordination assessments. The results are expected to inform future training programs by optimizing athletic performance and supporting injury prevention strategies in youth sailing.
