Influence of physical training on erythrocyte concentrations of iron, phosphorus and magnesium

Abstract

Background: The present study aimed to determine changes occurring in the erythrocyte concentrations of Iron (Fe), Magnesium (Mg) and Phosphorous (P) of subjects with different levels of physical training living in the same area of Extremadura (Spain). Methods: Thirty sedentary subjects (24.34 ± 3.02 years) without sports practice and a less active lifestyle, formed the control group (CG); 24 non-professional subjects (23.53 ± 1.85 years), who perform between 4 and 6 h/week of moderate sports practice without any performance objective and without following systematic training formed the group of subjects with a moderate level of training (MTG), and 22 professional cyclists (23.29 ± 2.73 years) at the beginning of their sports season, who performed more than 20 h/week of training, formed the high-level training group (HTG). Erythrocyte samples from all subjects were collected and frozen at − 80°C until analysis. Erythrocyte analysis of Fe, Mg and P was performed by inductively coupled plasma mass spectrometry (ICP-MS). All results are expressed in μg/g Hb. Results: The results showed that there were statistically significant lower concentrations of erythrocyte Fe, Mg and P in MTG and HTG than CG. All parameters (Fe, Mg and P concentrations in erythrocytes) correlated inversely with physical training. Conclusions: Physical exercise produces a decrease in erythrocyte concentrations of Fe, Mg and P. This situation could cause alterations in the performance of athletes given the importance of these elements. For this reason, we recommend an erythrocyte control at the beginning, and during the training period, to avoid harmful deficits.

Erythrocyte concentrations of chromium, copper, manganese, molybdenum, selenium and zinc in subjects with different physical training levels

“…The materials and methods are the same as described previously in Maynar-Mariño et al, (2020) [4]. However, they are explained again below.…”

“…The body concentration of micronutrients is usually determined by measuring the trace elements in plasma; however, the plasma concentration of these elements may fluctuate regardless of nutritional status [3]. Previous studies have observed a decrease in erythrocyte concentrations of other macro minerals, such as magnesium, phosphorus and iron in athletes, compared with a control group [4]. However, very few studies have determined the erythrocyte concentrations of trace elements, and the influence of physical training.…”

Iron and Physical Activity: Bioavailability Enhancers, Properties of Black Pepper (Bioperine®) and Potential Applications

“…Some studies [ 32 , 33 , 34 , 35 ] indicate that the concomitant use of vitamin C (ascorbic acid), vitamin A, vitamin E, vitamin B9 (folic acid), vitamin B12 (cobalamin) and vitamin D3 (cholecalciferol) increases the bioavailability and absorption of Fe in the intestinal tract. These absorption enhancers can be provided by diet or direct supplementation preparations.…”

Machine Learning Based Distribution of Sports Video Stream Assisting Physical Training

“…The connotation of physical training should be the training of human body to improve the ability of walking, running, jumping, and throwing. Physical training has its systematic characteristics, that is, the integrity and comprehensiveness of training [6][7][8]. Physical training should combine the characteristics of sports and human body and cross disciplines through multidisciplinary support, and learn from and integrate the excellent achievements and advanced experience in other fields, so as to optimize the bone, joint, muscle, and sports auxiliary system of human body sports system and the large system of sports training in physical training [9,10].…”
