Abstract

Background: Free radicals play essential roles in the aging and various pathological processes. Antioxidants may be helpful to prevent these conditions. Therefore, the body should have high antioxidant values and carotenoids can be a representative of antioxidants.

Objectives: The purpose of the study was to use the BioPhotonic Scanner S3 and resonant Raman spectroscopy technology for comparing the skin carotenoid values between those who exercised frequently and those who did not exercised within a 6-month period.

Methods: Four equal groups of six hundred male and female volunteers, ages 20 to 60 years, who resided in Bangkok Metropolitan Region were formed, with 150 subjects in each group: 1) cardiorespiratory training, 2) resistance training, 3) flexibility training, and 4) non exercising.

Results: The individuals with flexibility training had the highest carotenoid values compared to the other groups (36,847 ± 1,053 vs. 32,413 ± 535 units, respectively). Females had higher carotenoid values than males (36,182 ± 773 vs. 29,245± 694 units) Obese people who had body mass index ≥ 25 kg/m2 showed lower carotenoid values than the others (28,519± 844 vs. 32,413± 535 units) Finally, the advancing age was positively correlated with the carotenoid values (r = 0.257, P < 0.001). Furthermore, all four factors showed significant correlations with the carotenoid levels on a multivariate analysis.

Conclusion: The exercise with the highest carotenoid values is flexibility training, followed by cardiorespiratory training, resistance training and non- exercising, respectively. Furthermore, high carotenoid levels were related with adolescent, female gender, and lower body mass index.
