Abstract
To analyze the correlation between body weight, body mass index (BMI), fat mass (FM), lean mass (LM), and biochemical indicators at various stages of physical training, and to investigate the relationship between bone mineral density (BMD), body composition, and biochemical indicators. This research aims to provide insights for the scientific training of Chinese handicapped snowboarding athletes.
Utilizing 12 male athletes from the Chinese National Handicapped Team as participants, this study implemented an eight-week physical training regimen consisting of three phases: endurance training, maximum strength training, and rapid strength training. Body composition and BMD were assessed using dual-energy X-ray absorptiometry. Blood analysis was conducted to measure biochemical indicators such as ferritin (Fer), calcium (Ca), phosphorus (P), magnesium (Mg), and other relevant parameters. Results: 1) The athletes demonstrated an increase in body weight, LM, FM, and BMD. 2) The BMD of the athletes exhibited a moderate inverse correlation with LM and FM in all regions except the trunk and android region, as well as body weight. Additionally, the concentrations of Ca, calcium-phosphorus product (Ca×P), and Fer showed a moderate positive association with the BMD of the athletes.
