The aim of this study was to evaluate the nutrition knowledge of Finnish endurance athletes and their coaches. Our study is the first of its kind in Finland. The evaluation was carried

Endurance athletes commonly believe sodium intake improves performance and prevents health consequences of endurance exercise, including exercise-associated muscle cramps (EAMC) and exercise-associated hyponatremia (EAH) ( Winger et al., 2011 , 2013 ).

A balanced diet with an appropriate energy intake supports optimal body function ( Thomas et al., 2016 ) and is, together with regular physical activity, the cornerstone of a healthy lifestyle. However, exercising women and female athletes focusing on leanness, such as endurance athletes, are

Although this is important for all athletes, endurance athletes with

Countermovement jump (CMJ) and maximum running speed over a distance of 20 m were evaluated for examination of the concurrent fatigue and post-activation potentiation (PAP) in endurance athletes after an incremental feld running test.
Twenty-two endurance athletes performed two attempts of CMJ on a force plate and maximum running speed test before and following the Université de Montréal Track Test (UMTT).
The results showed an improvement in CMJ height (3.6%) after UMTT that correlated with the increment in peak power (3.4%), with a concurrent peak force loss (–10.8%) that correlated with peak power enhancement. The athletes maintained their 20 m sprint performance after exhaustion. Cluster analysis reinforced the association between CMJ and peak power increments in responders with a reported correlation between peak power and sprint performance increments (r = .623; P = .041); nonresponders showed an impairment of peak force, vertical stiffness, and a higher vertical displacement of the center of mass during the countermovement that correlated with lactate concentration (r = –0.717; P = .02).
It can be suggested that PAP could counteract the peak force loss after exhaustion, allowing the enhancement of CMJ performance and the maintenance of sprint ability in endurance athletes after the UMTT. From these results, the evaluation of CMJ after incremental running tests for the assessment of muscular adaptations in endurance athletes can be recommended.

The CON diet was designed to meet the lower end of the range of recommended CHO intakes for endurance athletes ( Thomas et al., 2016 ), providing 6 g/kg of BM CHO daily, with 30 g/hr of CHO consumed during training sessions exceeding 60 min in duration.

The latter is typically speed (in meters per second) and power output (in watts). Objective internal markers are first and foremost oxygen uptake (VO 2 ), heart rate (HR
