Creatine is a naturally occurring substance in the human body that is used to produce energy for activities like resistance training and sprinting. Research has focused on creatine and these types of activities in athletes, however, there is minimal research done with non-athlete populations. In addition to this gap in the literature, there are very few studies that consider evaluating maximal volume of oxygen consumption (VO2max) when supplementing creatine. The purpose of this study is to investigate the effects of creatine supplementation on VO2max in a recreationally-active population while undergoing a hybrid training program. The hybrid training program consists of 3 cardiovascular training sessions and 2 resistance training sessions per week. The reason for choosing this program is due to its current trend in the American fitness culture as well as its ability to replicate an “average” fitness program. The study is 4 weeks long and involves 30 participants (15 Males, 15 Females) randomly assigned to either the control group or the experimental group. All participants are taking 0.1g/kg of body weight of their respective substance (creatine monohydrate for the experimental group or a glucose powder for the control group). Their VO2max will be tested pre-training (immediately prior to beginning the training program and supplementation) and post-training (within 5 days of completing the training program and supplementation). The differences between pre-training and post-training VO2max values will be evaluated via ANOVA. This study’s results will provide insight into the effects of creatine supplementation on VO2max in a recreationally-active population as well as guidance when deciding if creatine supplementation should be consumed when performing an “average” fitness routine.
