Treadmill Aerobic Training and Quality of Life in Anemic Females

Iron deficiency anemia (IDA) is deeply associated with marked fatigue, diminished neuromuscular efficiency, and cardiorespiratory deconditioning. While standard medical management relies purely on pharmacological iron supplements to normalize hematological indices, this approach does not directly restore functional aerobic capacity or skeletal muscle utilization efficiency.

This study employs a parallel-group randomized controlled trial design (1:1 allocation) comparing two approaches over 8 consecutive weeks:

• Experimental Group (Group A, n=30): Standard physician-prescribed oral iron supplementation plus a structured moderate-intensity treadmill aerobic exercise program (3 sessions per week, progressing from 35 to 40 minutes at 60-70% max HR), alongside standard nutrition guidelines (the '2-Hour Rule' for iron absorption and daily Blackstrap Molasses).
• Control Group (Group B, n=30): Standard physician-prescribed oral iron supplementation and nutritional guidelines alone, with no structured exercise program.

Functional physical fitness is evaluated at baseline and post-treatment using the Physical Fitness Index (PFI) derived from the submaximal 3-minute Harvard Step Test. Health-related quality of life is assessed via the 12-item Short-Form Health Survey (SF-12), evaluating both Physical Component Summary (PCS) and Mental Component Summary (MCS) dimensions. The research evaluates whether systematic physical therapy/aerobic work is a mandatory adjuvant to reverse physical deconditioning in young females.

Inclusion criteria

• Age between 18 to 28 years.
• Biological females.
• Clinically diagnosed with mild-to-moderate Iron Deficiency Anemia (IDA), documented by laboratory Complete Blood Count (CBC) showing Hemoglobin (Hb) levels strictly between 9.0 and 12.0 g/dL, and serum ferritin levels ranging from 15 to 150 ng/mL.
• Hemodynamically stable and medically cleared to safely participate in moderate-intensity aerobic exercise.
• Regularly receiving physician-prescribed standard medical care (e.g., oral iron supplementation)

Exclusion criteria

• Severe anemia (Hemoglobin levels below 9.0 g/dL).
• Pregnancy or lactation.
• Chronic respiratory diseases, including bronchial asthma or COPD.
• Acute or chronic cardiovascular instability (e.g., severe arrhythmias, uncontrolled hypertension, or structural heart disease).
• Affected by chronic diseases or adhering to regular medication regimens (other than prescribed iron).
• Neurological or musculoskeletal disorders that mechanically limit the ability to walk on a treadmill or perform the step test safely.
• Experiencing acute illness, systemic infection, menorrhagia, irregular menstruation, or fever at the time of the study.
• Active participation in other structured, vigorous athletic training programs.
• Cognitive impairment affecting patient cooperation or the ability to understand the study questionnaires
