Background: Exercise represents an important challenge for the homeostasis of the entire body that occurs on a cellular and systemic level in which micronutrients play an important role in regulating the processes that sustain athletic performance. Objective: The investigators measured changes in gene expression of whole blood in a group of athletes and sedentary participants and compared gene modulation before and after nutritional intervention with micronutrients. Methods: Blood samples were taken from thirteen athletes and thirteen sedentary age- and gender-matched participants. The study design was carried out over a period of 4 months where three time points were established: (T0) baseline conditions in the sedentary and athlete groups; (T2) after two months of supplementation; (T4) after two months in the absence of nutritional supplementation. Differential gene expression was evaluated in 112 genes using RT-qPCR analysis with the QuantStudioTM 12K Flex Real-Time PCR System.

Primary | Gene expression analysis | 112 genes using RT-qPCR analysis with the QuantStudioTM 12K Flex Real-Time PCR System. Relative quantification was determined using the 2-?CT method. Cut-off punctuation was established as 1.5. | 6 months | |
Secondary | Anthropometric assessment - Height | Anthropometric assessment recorded data were height in centimetres (SECA® Model 274). | 6 months | |
Secondary | Anthropometric assessment - Weight | Anthropometric assessment recorded data were weight in kilograms (Tanita MC-980 Body Composition Analyzer MA Multifrequency Segmental, Barcelona, Spain). | 6 months | |
Secondary | Anthropometric assessment - BMI | Anthropometric assessment recorded data BMI was calculated calculated as weight/height^2 and expressed kg/m2 equation. | 6 months | |
Secondary | Anthropometric assessment - Fat percentage | Anthropometric assessment recorded data BMI was measured by multifrequency bioelectrical impedance (Tanita MC-980 Body Composition Analyzer MA Multifrequency Segmental, Barcelona, Spain) and expressed in kilograms and as the percentage of body fat. Participants were informed in advance of the required conditions prior to the measurement: no alcohol less than 24 hours before the measurement, no vigorous exercise less than 12 hours prior to the measurement, no food or drink less than 3 hours prior to the measurement, and no urination immediately before the measurement. All measurements were taken simultaneously during the morning in fasting conditions. | 6 months | |
Secondary | Anthropometric assessment - Fat free mass | Anthropometric assessment recorded data fat free mass was measured by multifrequency bioelectrical impedance (Tanita MC-980 Body Composition Analyzer MA Multifrequency Segmental, Barcelona, Spain) and expressed in kilograms and as the percentage of fat-free mass. Participants were informed in advance of the required conditions prior to the measurement: no alcohol less than 24 hours before the measurement, no vigorous exercise less than 12 hours prior to the measurement, no food or drink less than 3 hours prior to the measurement, and no urination immediately before the measurement. All measurements were taken simultaneously during the morning in fasting conditions. | 6 months | |
Secondary | Anthropometric assessment - Muscle mass | Anthropometric assessment recorded data muscle mass was measured by multifrequency bioelectrical impedance (Tanita MC-980 Body Composition Analyzer MA Multifrequency Segmental, Barcelona, Spain) and expressed in kilograms. Participants were informed in advance of the required conditions prior to the measurement: no alcohol less than 24 hours before the measurement, no vigorous exercise less than 12 hours prior to the measurement, no food or drink less than 3 hours prior to the measurement, and no urination immediately before the measurement. All measurements were taken simultaneously during the morning in fasting conditions. | 6 months | |

Creatinine was measured and expressed in mg/dL. The reference value is established in 0.5 - 0.9 mg/dL. | At baseline | |
Secondary | Biochemical parameters - Urea | Biochemistry was performed after 12 hours of fasting first thing in the morning, by specialists puncturing the cubital vena cava (Venoject®). Urea was measured and expressed in mg/dL. The reference value is established in 10 - 50 mg/dL. | At baseline | |
Secondary | Biochemical parameters - Uric acid | Biochemistry was performed after 12 hours of fasting first thing in the morning, by specialists puncturing the cubital vena cava (Venoject®). Uric acid was measured and expressed in mg/dL. The reference value is established in 2.4 - 5.7 mg/dL. | At baseline | |
Secondary | Biochemical parameters - Triglycerides | Biochemistry was performed after 12 hours of fasting first thing in the morning, by specialists puncturing the cubital vena cava (Venoject®). Triglycerides acid was measured and expressed in mg/dL. The reference value is established in 50 - 200 mg/dL. total cholesterol (mg/dL), total proteins (g/dL), transferrin (mg/dL) and albumin (mg/dL). |
At baseline | |
Secondary | Biochemical parameters - Total cholesterol | Biochemistry was performed after 12 hours of fasting first thing in the morning, by specialists puncturing the cubital vena cava (Venoject®). Total cholesterol was measured and expressed in mg/dL. The reference value is established in 110 - 200 mg/dL. | At baseline | |
Secondary | Biochemical parameters - Total proteins | Biochemistry was performed after 12 hours of fasting first thing in the morning, by specialists puncturing the cubital vena cava (Venoject®). Total proteins were measured and expressed in mg/dL. The reference value is established in 6.6 - 8.7 g/dL. | At baseline | |
Secondary | Biochemical parameters - Transferrin | Biochemistry was performed after 12 hours of fasting first thing in the morning, by specialists puncturing the cubital vena cava (Venoject®). Transferrin was measured and expressed in mg/dL. The reference value is established in 200 - 360 mg/dL. | At baseline | |
Secondary | Biochemical parameters - Albumin | Biochemistry was performed after 12 hours of fasting first thing in the morning, by specialists puncturing the cubital vena cava (Venoject®).
