Effects of 8-Week CrossFit-Based Concurrent Training on Fitness, Body Composition, and Psychological Outcomes in Schoolchildren
Summary
A randomized controlled trial (NCT07552844) registered on ClinicalTrials.gov will examine the effects of an 8-week CrossFit-based concurrent training program on schoolchildren aged 7-11 years. The study will enroll 30 participants split into an experimental group (n=15) receiving twice-weekly adapted CrossFit sessions and a control group (n=15) maintaining their usual routine without structured physical training. Researchers will assess pre- and post-intervention changes in strength, cardiorespiratory fitness, body composition, and psychological variables including anxiety, stress, and self-esteem using field-based physical tests and validated questionnaires.

About this source
ClinicalTrials.gov is the NIH-run registry of every clinical trial conducted in the United States, plus most international trials sponsored by US-based companies or institutions. By federal law, sponsors must register Phase 2 through Phase 4 studies before enrolling patients and post results within a year of completion. This feed tracks every new trial registration and study update, around 700 a month: drug interventions, device studies, behavioral protocols, observational research. Watch this if you scout drug candidates moving into mid or late-stage development, monitor competitor pipelines, or follow rare disease research where new trials signal patient hope. GovPing parses sponsor, phase, intervention, and target indication on each entry.
What changed
This document registers a new clinical trial (NCT07552844) on ClinicalTrials.gov, describing a randomized controlled trial to evaluate the effects of an 8-week CrossFit-based concurrent training program in schoolchildren aged 7-11. The trial will compare an experimental group (n=15) receiving twice-weekly adapted CrossFit sessions against a control group (n=15) maintaining their usual routine. Assessment measures include field-based physical tests (CMJ, Course Navette, handgrip strength) and validated psychological questionnaires.
Affected parties include clinical investigators conducting exercise-based intervention research, educational institutions hosting school-based fitness programs, and healthcare providers involved in pediatric physical fitness assessment. The registration indicates the study will follow Good Clinical Practice standards for pre- and post-intervention outcome measurement.

Effects of 8-Week CrossFit-Based Concurrent Training on Fitness, Body Composition, and Psychological Outcomes in Schoolchildren

Abstract
This study examines the effects of an 8-week CrossFit-based concurrent training program in boys and girls aged 7 to 11 years, comparing an experimental group (n=15) with a control group (n=15). The aim is to assess changes in strength, cardiorespiratory fitness, body composition, and psychological variables such as anxiety, stress, and self-esteem, using field-based physical tests (CMJ, Course Navette, handgrip strength, etc.) and validated questionnaires. The study follows a randomized controlled trial design with pre- and post-intervention assessments. The experimental group will complete two weekly CrossFit sessions adapted for children, while the control group will maintain their usual routine without structured physical training. The hypothesis states that the intervention will significantly improve both physical performance and psychological well-being in the experimental group compared to the control group.
