Pre-exercise left leg flexibility (LFlex pre) correlated negatively with post-exercise pH (r = 0.702, \(p\) = 0.007), protein (r = 0.669, \(p\) = 0.012), and glucose (r = 0.735, \(p\) = 0.004), while pre-exercise right leg flexibility (RFlex pre) correlated negatively with post-exercise color (r = 0.569, \(p\) = 0.043), pH (r = 0.630, \(p\) = 0.021), and protein (r = 0.572, \(p\) = 0.041). Post-exercise LFlex correlated negatively with post-exercise protein (r = 0.554, \(p\) = 0.040) and pH (r = 0.579, \(p\) = 0.030). Post-exercise RFlex correlated negatively with post-exercise FVC (r = 0.509, \(p\) = 0.031). Post-exercise rate of perceived exertion (RPE post) correlated negatively with pre-exercise left scapular dyskines (LDisk pre, r = 0.678, \(p\) = 0.003) and right scapular dyskines (RDisk pre, r = 0.688, \(p\) = 0.002). Pre-exercise left leg stability (LST pre) correlated negatively with post-exercise body temperature (BT post, r = 0.553, \(p\) = 0.021) and post-exercise glucose (r = 0.576, \(p\) = 0.039). Pre-exercise right leg stability (RST pre) also correlated negatively with post-exercise body temperature (BT post, r = 0.814, \(p\) = 0.000) and glucose (r = 0.576, \(p\) = 0.039). Pre-exercise left foot [PERSON]'s test (LJack pre) correlated negatively with post-exercise lactate (r = 0.604, \(p\) = 0.013) and critical flicker fusion threshold arousal (CFFT post, r = 0.670, \(p\) = 0.005). Similarly, pre-exercise right foot [PERSON]'s test (RJack pre) correlated negatively with post-exercise lactate (r = 0.604, \(p\) = 0.013) and CFFT post (r = 0.670, \(p\) = 0.005). In the 13 km Super distance, several positive correlations were found. Pre-exercise left leg flexibility (LFlex pre) was positively correlated with the post-exercise rate of perceived exertion (RPE post, r = 0.436, \(p\) = 0.030). Pre-exercise right leg flexibility (RFlex pre) was positively correlated with post-exercise protein levels (Protein post, r = 0.424, \(p\) = 0.049). Pre-exercise right scapular dyskines (RDisk pre) showed a positive correlation with pre-exercise glucose levels (Glucose pre, r = 0.450, \(p\) = 0.010). Pre-exercise right foot [PERSON]'s test (RJack pre) was positively correlated with pre-exercise heart rate (HR pre, r = 0.498, \(p\) = 0.002). Pre-exercise left foot navicular drop (LDrop pre) showed positive correlations with post-exercise forced vital capacity (FVC post, r = 0.487, \(p\) = 0.009), pre-exercise glucose levels (Glucose pre, r = 0.463, \(p\) = 0.008), post-exercise glucose levels (Glucose post, r = 0.443, \(p\) = 0.039), and pre-exercise critical flicker fusion threshold arousal (CFFT pre, r = 0.484, \(p\) = 0.004). Pre-exercise right foot navicular drop (RDrop pre) was positively correlated with pre-exercise coordinative and arm-using capacities (CCA pre, r = 0.398, \(p\) = 0.015), pre-exercise forced expiratory volume in the first second (Fev1 pre, r = 0.337, \(p\) = 0.044), and post-exercise forced vital capacity (FVC post, r = 0.400, \(p\) = 0.035). Post-exercise left leg flexibility (LFlex post) showed positive correlations with pre-exercise blood oxygen saturation (BOS pre, r = 0.451, \(p\) = 0.024), pre-exercise pH (pH pre, r = 0.444, \(p\) = 0.038), and post-exercise rate of perceived exertion (RPE post, r = 0.452, \(p\) = 0.030). Post-exercise right leg flexibility (RFlex post) was positively correlated with pre-exercise blood oxygen saturation (BOS pre, r = 0.434, \(p\) = 0.030) and pre-exercise pH (pH pre, r = 0.499, \(p\) = 0.018). Post-exercise right scapular dyskines (RDisk post) was positively correlated with pre-exercise coordinative and arm-using capacities (CCA pre, r = 0.443, \(p\) = 0.021). Post-exercise left foot [PERSON]'s test (LJack post) showed positive correlations with pre-exercise heart rate (HR pre, r = 0.508, \(p\) = 0.010) and post-exercise heart rate (HR post, r = 0.600, \(p\) = 0.001).
