Background Stamina is a key component within all major tasks necessary for proper motor function. Particularly in individuals in the second half of their lifespan, there is a direct correlation between diminished stamina and increased morbidity and mortality rates. Currently, there are numerous studies validating the relationship between stamina and varying physical capabilities. In this contex...

We present Stamina, a tool solving three algorithmic problems in automata theory. First, compute the star height of a regular language, i.e. the minimal number of nested Kleene stars needed for expressing the language with a complement-free regular expression. Second, decide limitedness for regular cost functions. Third, decide whether a probabilistic leaktight automaton has value 1, i.e. wheth...

Oakbrook Terrace, Ill. (April 2, 2018)—A new study in the Democratic Republic of Congo (DRC) found that treating women subsistence farmers with just a single dose of a cheap deworming medication significantly improved their physical stamina for the grueling agriculture work needed for their family’s survival. The results of treatment could be twofold: improved health for farming women and incre...

Physiological capacities may constrain behavioural options and hence have important ecological consequences. We tested the hypothesis that social dominance is related to capacities for locomotor performance in territorial male lizards (Sceloporus occidentalis Baird & Girard). We first measured the maximal sprint speed and stamina of individual lizards in the laboratory. Pairs of size-matched ma...

Swimming stamina, measured as time-to-fatigue, was reduced by approximately two-thirds in rainbow trout experimentally infected with Ichthyophonus. Intensity of Ichthyophonus infection was most severe in cardiac muscle but multiple organs were infected to a lesser extent. The mean heart weight of infected fish was 40% greater than that of uninfected fish, the result of parasite biomass, infiltr...

We consider a tournament among four equally strong semifinalists. The players have to decide how much stamina to use in the semifinals, provided that the rest is available in the final and the third-place playoff. We investigate optimal strategies for allocating stamina to the successive matches when players' prizes (payoffs) are given according to the tournament results. From the basic assumpt...

Swimming stamina in adult fish is heritable, it is unknown if inherited traits that support enhanced swimming stamina in offspring appear only in juveniles and/or adults, or if these traits actually appear earlier in the morphologically quite different larvae. To answer this question, mature adult zebrafish (Danio rerio) were subjected to a swimming performance test that allowed separation into...
