The purposes of this dissertation were to 1) determine the effectiveness of the neutrophillymphocyte ratio (NLR) as an athlete monitoring tool in resistance training and 2) determine if repetition maximum or relative intensity loading scheme is superior in managing fatigue through the hormonal, inflammatory, and performances response throughout a 10-week periodized resistance training program. Results from the dissertation give merit to continued research regarding the use of NLR as a monitoring tool to help determine the degree of recovery. Furthermore, results from this dissertation lead to questioning the effectiveness of using a repetition maximum (RM) loading scheme within a periodized training model. Results indicated statistical significant time x group interaction effects for training strain and T:C, statistical main effects for time for NLR, IPF, and IPFa. Under an identical programming model, RM loading subjects experienced a 48.7% increase in training strain over the course of ten weeks. This intensification in training strain likely contributed to the increased negative immune and endocrine response the RM subjects experienced when compared to the relative intensity (RISR) group. When dissecting the individual pre-post performance results, the three largest decreases in static jump height (out of four) participated in the RM loading group. Additionally, only two subjects experienced decreases in their maximal strength (based on isometric mid-thigh pull), both of which participated in the RM loading group. Lastly, it is highly likely that one subject from the RM group was at exceedingly high risk of entering a state overtraining. At a minimum, the subject entered a state of a nonfunctional overreach, based on an increase in cortisol concentrations, NLR, T:C levels, along with decreases in testosterone concentrations and maximal strength performance. When combined, results suggest that using an RM loading scheme and a periodized model may not allow for adequate recovery, especially during phases where recovery is of utmost importance (e.g. a taper).
