Abstract

Obesity prevalence is high among young adults (18 – 29 years of age). The goal of this study was to determine the effect of varying ratios of resistance and cardiovascular training on aerobic capacity, muscular strength, and anthropometric measurements in college students. For six weeks, participants were allocated to one of two training groups: cardiovascular (CT) (n = 6) or mixed (MT) (n = 7). Participants followed a given protocol for six weeks and aerobic capacity was assessed at week 0, 2, 4, and 6 by metabolic cart. Muscular strength was measured as bicep, triceps, and leg extension maximum-length holds, performed biweekly. Bodyweight and bodyfat was measured biweekly. CT subjects exhibited a significant decrease in aerobic capacity over the 6- week period compared to individuals in the MT group (-7.59±8.34% vs. 3.70±5.26%, respectively, p=0.014). Leg strength saw a significant increase in the CT group (120±40%, p=0.002) but not in the MT group (110±179%, p>0.05). Bodyweight change was insignificant in both groups, but bodyfat decreased significantly in the MT group (-14.6±11.5%, p=0.01) while remaining unchanged in CT participants (2.1±9.0%, p>0.05). Noncompliance to protocols was due to a lack of time in 70% of cases. Our findings indicate that thirty minutes of cardiovascular exercise performed three times per week may be insufficient to maintain fitness in students. Additional resistance training may be a useful strategy to attenuate physical decline and improve body composition. Insufficient time should be addressed as a significant barrier to exercise in students.
