The article discusses research in applied sports science, with a focus on how endurance runners' running economy (RE) is affected by concurrent endurance and strength training. Topics include maximal strength training, 1 repetition maximum (1RM) and countermovement jumps, and resting metabolic rate.

The aim of this case study was to describe the physiological and regulatory processes, by means of heart rate (HR) monitoring and pacing strategy, in a top-level race walker (age: 32 years; height: 1.76 m; body mass: 62 kg; training volume: 130-150 km·wk) who was focused on the attainment of the 5-km indoor race walk (RW) World Record. The HRmean was 185 ± 14.9 b·min, with an HRmean/HRmax ratio of 0.96. Almost the whole race (91.8%) was performed to an intensity ?90% of the HRmax; lower intensity work was negligible (8.1%). The race profile was a reverse J-shaped pacing curve; in fact, the athlete completed the first 1,000 m in the fastest time, slowing during the middle 3,000 m, and increasing the speed during the final 1,000 m of the race. Despite the attempt failed (the athlete performed only the 2009 World leading performance, 18 minutes 23 seconds 47 tenths), these data suggest that a more linear strain distribution for the entire performance would be optimal instead of a fast-start strategy, which leads to a drastic decrement of the walking velocity. Moreover, this study supports the use of HR monitoring combined with the regulation of the effort to understand the physiological and regulatory processes during an indoor RW event.

The article presents research on quantifying the exertion level of gymnastics training for women gymnasts.in tumbling, trampette and floor exercise. It was found that session-rating of perceived exertion as measured by heart-rate zone was an effective means of monitoring the training load in relation to technical gymnastics skills.
