文章摘要：

this paper investigates the relationship between plasma trace element and plasma leptin, as well as percent fat mass, in 16 male basketball athletes. blood samples were obtained before intensive training and 24 h after intensive training to measure plasma zinc (zn), copper (cu), calcium (ca), magnesium (mg), iron (fe), and leptin levels. high-density lipoprotein cholesterol (hdl), low-density lipoprotein cholesterol (ldl), triglyceride (tg), total and cholesterol (tc) levels were determined using commercially available kits for humans. subjects presented similar values in terms of age (21.1 ± 2.2 years old), body mass index (23.9 ± 2.00 kg/m2), percent body fat (14.40 ± 1.52%), plasma hemoglobin (150.1 ± 9.4 g/l), plasma zn (17.47 ± 1.28 μmol/l), plasma cu (13.42 ± 1.40 μmol/l), plasma ca (2.41 ± 0.14 mmol/l), and plasma mg (0.96 ± 0.02 mmol/l). the correlation analysis between degree of plasma leptin and plasma element contents was performed using the spss 16.0 software. plasma zn correlated positively with plasma leptin (r = 0.746,p < 0.01), cu–zn sod (r = 0.827, p < 0.01), and negatively with percent fat mass (r = –0.598,p < 0.05) under no-training conditions. meanwhile, plasma cu, ca, mg, and fe did not correlate with plasma leptin or percent fat mass (p > 0.05). in conclusion, plasma zn may be involved in the regulation of plasma leptin and may serve as a lipid-mobilizing factor in chinese men's basketball athletes.
