Metabolic responses to a 48-h ultra-marathon run in middle-aged male amateur runners
Purpose
To evaluate ongoing metabolic changes during a 48-h competitive run and a 48-h recovery period, with focus on potential health risks exemplified by heart and skeletal muscle damage biomarkers and oxidative stress-related indices.
Methods
Blood samples were taken before the race, after 12, 24, and 48 h of running, and after 24 and 48 h of recovery from male amateur runners (
N
= 7, age 35–59 years, VO
2max
mean ± SD 57.0 ± 4.0 ml kg
−1
min
−1
, total distance covered 183–320 km). The samples were analyzed for morphology, acid–base and electrolyte balance, iron status, lipid profile, interleukin-6, high-sensitivity C-reactive protein, N-terminal pro-brain-type natriuretic peptide, high-sensitivity cardiac troponin T, non-enzymatic antioxidants, activities of selected enzymes including antioxidant enzymes, and total antioxidant status.
Results
The sustained ultra-endurance run caused hypocapnic alkalosis with slight hyperkalemia and hypocalcemia, but no hyponatremia. Blood biochemistry showed severe muscle but not liver damage, and an acute inflammatory response. These effects were evidenced by leukocytosis, several fold rises in interleukin-6 and high sensitivity C-reactive protein, extreme elevations in serum levels of muscle enzymes, and marked increases in cardiac biomarker levels. Most of the changes dissolved during the 48 h post-race recovery. Neither the iron pool, nor erythropoiesis, nor pro-oxidant/antioxidant balance were substantially affected.
Conclusions
The changes consequent on the ultra-endurance run do not pose a serious health risk in men who begin their endeavor with ultra-endurance running in mid-life. There is some circumstantial evidence that hyperventilatory hypocapnia may modulate inflammatory response by stimulating the release of interleukin-6 from working skeletal muscles.

The right ventricle following ultra-endurance exercise: insights from novel echocardiography and 12-lead electrocardiography
Purpose
There is contradictory evidence related to the impact of ultra-marathon running on right ventricular (RV) structure and function. Consequently, the aims of this study were to: (1) comprehensively assess RV structure and function before and immediately following a 100-mile ultra-marathon in highly trained runners, (2) determine the nature of RV recovery 6 h post-race, and (3) document 12-lead electrocardiogram (ECG) changes post-exercise.
Methods
Echocardiography and 12-lead ECG were assessed in 15 competitors in a repeated measures design before and immediately after completion of the 2013 Western States Endurance Race. A subset of nine was reassessed 6 h into recovery. Standard echocardiography was used to determine RV size, function and wall stress. Myocardial speckle tracking (MST) provided peak, time to peak and temporal indices for RV longitudinal strain and strain rates (
ε
and SR).
Results
RV size was increased post-race (inflow tract 14 %, outflow tract 11 %,
P
= 0.004 and 0.002). RV wall stress was elevated by 11 % post-race. Peak RV
ε
was reduced by 10 % (
P
= 0.007) and significantly delayed post-race (
P
= 0.008). Most changes in RV function persisted at the 6-h assessment. Post-race there was an increase in the prevalence of right-sided ECG changes.
Conclusions
Completion of a 100-mile ultra-marathon resulted in acute changes in RV structure and function that persisted 6 h into recovery and are consistent with sustained exposure to an elevated RV wall stress. These findings were supported by right-sided changes to the 12-lead ECG.

Perpetual Motion, Time, and Power: Christoph Ransmayr's Cox as Novel of the Anthropocene
Christoph Ransmayr's novels are known for complex interactions with time and the reimaging of historical events. This article considers the function of historical imagination in Cox oder der Lauf der Zeit (2016). The novel's fictional transposition to China of an eighteenth‐century quest for perpetual motion serves to link the control of time to the unprecedented worldly power of the Chinese emperor, but also to the decline of that power vis‐à‐vis the rise of industrial capitalism. The novel layers together the histories of perpetual motion and renewable energy, connecting both to emergent human geological agency. By framing this agency as the expression of the power of a few individuals, the novel opens spaces in which we can imagine a kind of thinking that might confront the constraints placed upon all of humanity by the actions of small groups in the past.

The effect of prior exercise intensity on oxygen uptake kinetics during high-intensity running exercise in trained subjects
Purpose
The aim of this study was to compare the effects of two different kinds of prior exercise protocols [continuous exercise (CE) versus intermittent repeated sprint (IRS)] on oxygen uptake (
V
O
2
) kinetics parameters during high-intensity running.
Methods
Thirteen male amateur futsal players (age 22.8 ± 6.1 years; mass 76.0 ± 10.2 kg; height 178.7 ± 6.6 cm;
V
O

58.1 ± 4.5 mL kg

) performed a maximal incremental running test for the determination of the gas exchange threshold (GET) and maximal

). On two different days, the subjects completed a 6-min bout of high-intensity running (50 % ∆) on a treadmill that was 6-min after (1) an identical bout of high-intensity exercise (from control to CE), and (2) a protocol of IRS (6 × 40 m).
Result
We found significant differences between CE and IRS for the blood lactate concentration ([La]; 6.1 versus 10.7 mmol L

, respectively),
V

baseline (0.74 versus 0.93 L min

, respectively) and the heart rate (HR; 102 versus 124 bpm, respectively) before the onset of high-intensity exercise. However, both prior CE and prior IRS significantly increased the absolute primary
V

amplitude (3.77 and 3.79 L min

, respectively, versus control 3.54 L min

), reduced the amplitude of the
V

slow component (0.26 and 0.21 L min

, respectively, versus control 0.50 L min

), and decreased the mean response time (MRT; 28.9 and 28.0 s, respectively, versus control 36.9 s) during subsequent bouts.
Conclusion
This study showed that different protocols and intensities of prior exercise trigger similar effects on

Ultra-endurance sports have no negative impact on indices of arterial stiffness
Purpose
Marathon running has been linked with higher arterial stiffness. Blood pressure is a major contributor to pulse wave velocity (PWV). We examined indices of arterial stiffness with a blood pressure-independent method in marathon runners and ultra-endurance athletes.
Methods
Male normotensive amateur runners were allocated to three groups according to former participation in competitions: group I (recreational athletes), group II (marathon runners) and group III (ultra-endurance athletes). Indices of arterial stiffness were measured with a non-invasive device (VaSera VS-1500N, Fukuda Denshi, Japan) to determine the cardio-ankle vascular index (CAVI, primary endpoint) and brachial-ankle PWV (baPWV). Lifetime training hours were calculated. Cumulative competitions were expressed as marathon equivalents. Linear regression analysis was performed to determine predictors for CAVI and baPWV.
Results
Measurements of arterial stiffness were performed in 51 subjects (mean age 44.6 ± 1.2 years): group I (
n
= 16), group II (
n
= 19) and group III (
n
= 16). No between-group differences existed in age, anthropometric characteristics and resting BP. CAVI and baPWV were comparable between all groups (
P
= 0.604 and
P
= 0.947, respectively). In linear regression analysis, age was the only independent predictor for CAVI (
R
2
= 0.239,
β
= 0.455,
P
= 0.001). Systolic BP was significantly associated with baPWV (
R
2
= 0.225,
β
= 0.403,
P
= 0.004).
Conclusions
In middle-aged normotensive athletes marathon running and ultra-endurance sports had no negative impact on arterial stiffness.
