The goal of this study was to determine whether traditional ergoespirometric incremental exercise testing carried out to the point of exhaustion could be useful in distinguishing the physiological profiles of elite runners that compete in races that lasted about 8 minutes versus those that lasted about 2 hours. Ten male marathon runners (performance time: 2:12:04, coefficient of variation (CV) ...

This study investigated if there were acute interference effects of strength exercises on subsequent continuous and intermittent 5Km aerobic exercises. Eleven physically active males (23.1 ± 3.1 yrs, 1.75 ± 0.07 m, 70.5 ± 8.8 kg, and 58.2 ± 8.3 VO2max) performed the following experimental sessions: A) 5 sets of 5 RM on the leg press followed by a 5km run performed continuously (average velocity...

the aim of this study was to assess the effect of four weeks of high intensity aerobic interval football training on aerobic performance indices in soccer players. 18 soccer players in iran azadegan league (age 21.88+2.24 yr, height 174.22+5.33 cm, weight 67.7+5.7 kg, body fat percent 12.38+3.29) volunteered to participate in this study and divided into two groups (training, 12 players; control...

Aims: The study aimed to evaluate the effects of a backward running (BR) training program prescribed by peak velocity (Vpeak_BR) on physiological variables and 3 km forward (FR) performance. Methods: Eight untrained male adults in took place study. All participants underwent five weeks BR based Vpeak_BR. They performed maximal incremental test treadmill determine oxygen uptake (V̇O2max) associat...

The aim of this study was to examine (i) the effects of a severe interval training period on oxygen pulse kinetics (O2-p, the ratio between VO2 and heart rate), and (ii) to study the consequences of these effects on the variation of performance (time to exhaustion) during severe runs. Seven athletes were tested before and after an eight-weeks period of a specific intermittent training at v Delt...

This study examined the hypothesis that running speed over 800- and 1,500-m races is regulated by the prevailing anaerobic (oxygen independent) store (ANS) at each instant of the race up until the all-out phase of the race over the last several meters. Therefore, we hypothesized that the anaerobic power that allows running above the speed at maximal oxygen uptake (VO2max) is regulated by ANS, a...
