Fitness centers are remarkably abundant in Cameroon. The aim of this work was to assess the effects of a 12-week training program on the anthropometric and physiological profiles of some participants in a fit-ness center. A total of 86 participants (40 from the experimental group and 46 from the control group) with age ranging from 17 to 53 years were subjected to pre- and posttraining assessments of, anthropomet-ric parameters, physiological parameters, and performance. Anthropo-metric parameters (weight, height, body mass index [BMI], waist cir-cumference [WC]) and blood pressure (diastolic blood pressure, systol-ic blood pressure [SBP]) were measured according to standard proto-cols. Heart rate was recorded using a heart rate monitor. Cardiorespira-tory fitness (maximal oxygen uptake or VO2peak) was estimated by the 20-multistage shuttle run test. All the data was collected twice within 12 weeks. Weight, BMI, and WC did not show any significant variation (P>0.05) after a 12-week training program. VO2peak increase was insig-nificant (P>0.05) higher in men (7.5%, P=0.06), compared to women (5.4%, P=0.4). We noticed a significant reduction (P=0.002) in the SBP of men. Significant increase of HR max was found in women. There was an improvement of 13.7% in the VO2peak of the participants who did not consume alcohol. These results demonstrate the slight benefits of a 12-week training program on health. The weight characteristics of the par-ticipants and lifestyle may play an important role in these interactions.
