RESUMO
Introduction: Aging is associated with elevated levels of some proinflammatory factors and exercise is a non-invasive intervention to improve immune function among older adults .The aim of the study was to compare resistance training effects on interlukine-6 [IL-6] and high-sensitivity C-reactive protein [hs-CRP] levels in older-aged women
Methods: The study was quasi-experimental and forty healthy females were selected and randomly assigned to one of four groups: strength after endurance training [endurance + strength [E + S], n = 9], strength prior to endurance training [strength + endurance [S + E], n = 10], interval resistance-endurance training [Int, n = 12], and control [n = 9] groups. The training program was performed for eight weeks, three times per week. Human TNF-alpha and IL-6 sandwich ELISA Kit were used. Within-group differences were analyzed using a paired samples t-test and between-group differences were analyzed using one-way analysis of variance
Results: The intra-session order had not significantly influence on the adaptive response of waist-to-hip ratio [p = 0.55], IL-6 [p = 0.55] and hs-CRP [p = 0.55] throughout the study. However, significant differences were shown following combined training between the S + E, E + S and Int groups for Vo2 max [p = 0.029], body mass [p = 0.016] and BMI [p = 0.023] when comparing pre and posttests
Conclusion: This study confirmed that adaptations to a combination of endurance and resistance training appear to be independent of whether resistance training occurs prior to or following endurance training
