This study aimed to evaluate the hematological factors and iron status in aerobic versus anaerobic training in athletic females.
In both the short and long term, physical training causes iron status deterioration in sporty females. Nonetheless, little is known about the effect of different forms of exercise (aerobic versus anaerobic) on haematological variables and iron status in sporty females during adolescence. As a result, the purpose of this study was to compare the haematological variables and iron status in aerobic versus anaerobic exercise in adolescent female athletes. Another goal was to compare aerobic and anaerobic groups in terms of iron status classifications, such as normal iron status, iron deficiency with or without anaemia.

Assessment of hemoglobin (Hb)
Blood samples were collected between 8:00 and 9:00 a.m. after an overnight fast and time of relaxation. The athletic girls were asked to refrain from exercising the day before sample. Blood was taken from the antecubital vein and placed in one EDTA tube and one beads tube for serum separation. An automatic cell counter (Sysmex XS 1000, Japan) was used to measure hemoglobin (Hb).
Time frame: 2 months
Assessment of hematocrit (Hct)
Blood samples were collected between 8:00 and 9:00 a.m. after an overnight fast and time of relaxation. The athletic girls were asked to refrain from exercising the day before sample. Blood was taken from the antecubital vein and placed in one EDTA tube and one beads tube for serum separation. An automatic cell counter (Sysmex XS 1000, Japan) was used to measure hematocrit (Hct).
Time frame: 2 months
Assessment of red blood cell (RBC) count
Blood samples were collected between 8:00 and 9:00 a.m. after an overnight fast and time of relaxation. The athletic girls were asked to refrain from exercising the day before sample. Blood was taken from the antecubital vein and placed in one EDTA tube and one beads tube for serum separation. An automatic cell counter (Sysmex XS 1000, Japan) was used to measure red blood cell (RBC) count.
Time frame: 2 months
Assessment of mean corpuscular volume (MCV)
Blood samples were collected between 8:00 and 9:00 a.m. after an overnight fast and time of relaxation. The athletic girls were asked to refrain from exercising the day before sample. Blood was taken from the antecubital vein and placed in one EDTA tube and one beads tube for serum separation. An automatic cell counter (Sysmex XS 1000, Japan) was used to measure mean corpuscular volume (MCV).
Time frame: 2 months
Assessment of mean corpuscular hemoglobin concentration (MCHC)
Blood samples were collected between 8:00 and 9:00 a.m. after an overnight fast and time of relaxation. The athletic girls were asked to refrain from exercising the day before sample. Blood was taken from the antecubital vein and placed in one EDTA tube and one beads tube for serum separation. An automatic cell counter (Sysmex XS 1000, Japan) was used to measure mean corpuscular hemoglobin concentration (MCHC).

Assessment of serum transferrin
Blood samples were collected between 8:00 and 9:00 a.m. after an overnight fast and time of relaxation. The athletic girls were asked to refrain from exercising the day before sample. Blood was taken from the antecubital vein and placed in one EDTA tube and one beads tube for serum separation. The serum sample was centrifuged, and the serum transferrin was measured using COBAS Integra 400 plus, Switzerland.
Time frame: 2 months
Assessment of serum ferritin
Blood samples were collected between 8:00 and 9:00 a.m. after an overnight fast and time of relaxation. The athletic girls were asked to refrain from exercising the day before sample. Blood was taken from the antecubital vein and placed in one EDTA tube and one beads tube for serum separation. The serum sample was centrifuged, and the serum ferritin was measured using ADVIA Centaur XPT, Germany.
Time frame: 2 months
Anthropometric measures
A weight-height scale was used to assess the weight (Kg) and height (m) for each female athlete in the two groups. The body mass index (BMI) was then calculated by dividing the weight by the height squared (Kg/m2).
Time frame: 2 months
Assessment of participation age to sport
Each female athlete was asked about her age of participation to sport to assess her training profile.
Time frame: 2 months
Assessment of number of hours of training per week
Each female athlete was asked about the number of hours of training per week to assess her training profile.
Time frame: 2 months
Assessment of training experience
The training experience in years was calculated by subtracting the female athlete's age of participation to training from her chronological age.
Time frame: 2 months
