Post-exercise right foot [PERSON]'s test (RJack post) was positively correlated with post-exercise heart rate (HR post, r = 0.562, \(p\) = 0.002) and post-exercise protein levels (Protein post, r = 0.440, \(p\) = 0.046). Post-exercise left foot navicular drop (LDrop post) was positively correlated with post-exercise glucose levels (Glucose post, r = 0.628, \(p\) = 0.002) and pre-exercise critical flicker fusion threshold arousal (CFFT pre, r = 0.620, \(p\) = 0.001). In the 13 km Super distance, the following negative bivariate correlations were found: Probe time negatively correlated with pre-exercise Abalakov jump (ABK pre, r = 0.418,\(p\) = 0.005), pre-exercise coordinative and arm-using capacities (CCA pre, r = 0.363, \(p\) = 0.017), pre-exercise forced expiratory flow between 25 and 75% (FFE25 pre, r = 0.322, \(p\) = 0.040), and post-exercise countermovement jump (CMJ post, r = 0.598, \(p\) = 0.001). It also showed negative correlations with post-exercise Abalakov jump (ABK post, r = 0.661, \(p\) = 0.000), post-exercise forced vital capacity (FVC post, r = 0.436, \(p\) = 0.018), pre-exercise isometric hand strength (IHS pre, r = 0.398, \(p\) = 0.012), and post-exercise isometric hand strength (IHS post, r = 0.416, \(p\) = 0.025). Additionally, change in countermovement jump (\(\Delta\)CMJ, r = 0.578, \(p\) = 0.001), change in pH (\(\Delta\)pH, r = 0.492, \(p\) = 0.027), and height (r = 0.356, \(p\) = 0.028) were negatively correlated with probe time. Pre-exercise left leg stability (LST pre) showed negative correlations with pre-exercise countermovement jump (CMJ pre, r = 0.394, \(p\) = 0.016), pre-exercise heart rate (HR pre, r = 0.345, \(p\) = 0.043), pre-exercise colour (Color pre, r = 0.402, \(p\) = 0.028), and post-exercise lactate (Lac post, r = 0.583, \(p\) = 0.001). Pre-exercise right leg stability (RST pre) negatively correlated with pre-exercise colour (Color pre, r = 0.371, \(p\) = 0.044), pre-exercise pH (pH pre, r = 0.545, \(p\) = 0.001), and pre-exercise protein levels (Protein pre, r = 0.484, \(p\) = 0.005). Pre-exercise left leg flexibility (LFlex pre) was negatively correlated with pre-exercise forced expiratory volume in the first second (Fev1 pre, r = 0.336, \(p\) = 0.045) and post-exercise critical flicker fusion threshold arousal (CFFT post, r = 0.422, \(p\) = 0.025). Pre-exercise left scapular dyskines (LDisk pre) negatively correlated with post-exercise heart rate (HR post, r = 0.522, \(p\) = 0.004), and pre-exercise right scapular dyskines (RDisk pre) also showed a negative correlation with post-exercise heart rate (HR post, r = 0.447, \(p\) = 0.017). Pre-exercise left foot Jack's test (LJack pre) was negatively correlated with pre-exercise isometric hand strength (IHS pre, r = 0.342, \(p\) = 0.044) and post-exercise isometric hand strength (IHS post, r = 0.498, \(p\) = 0.007). Pre-exercise left foot navicular drop (LDrop pre) negatively correlated with pre-exercise countermovement jump (CMJ pre, r = 0.363, \(p\) = 0.027), and pre-exercise right foot navicular drop (RDrop pre) showed a negative correlation with pre-exercise blood oxygen saturation (BOS pre, r = 0.430, \(p\) = 0.010). Post-exercise left leg stability (LST post) negatively correlated with pre-exercise protein levels (Protein pre, r = 0.463, \(p\) = 0.030) and post-exercise pH (pH post, r = 0.507, \(p\) = 0.019). Post-exercise left leg flexibility (LFlex post) showed negative correlations with pre-exercise Abalakov jump (ABK pre, r = 0.577, \(p\) = 0.002), pre-exercise coordinative and arm-using capacities (CCA pre, r = 0.593, \(p\) = 0.001), pre-exercise forced expiratory volume in the first second (Fev1 pre, r = 0.581, \(p\) = 0.002), pre-exercise forced expiratory flow between 25 and 75% (FFE25 pre, r = 0.466, \(p\) = 0.016), post-exercise forced expiratory volume in the first second (Fev1 post, r = 0.404, \(p\) = 0.037), post-exercise forced expiratory flow between 25 and 75% (FFE25 post, r = 0.466, \(p\) = 0.014), and post-exercise critical flicker fusion threshold arousal (CFFT post, r = 0.404, \(p\) = 0.037).
