The article discusses research conducted to investigate the variations of physiological and perceptual variables during a 10,000-meter race walking event in an effort to trace a performance profile of the distance. Researchers evaluated 14 male athletes. They found that they spent 95.4% at 90-100% of their peak heart rate and that during the race, a shift toward higher heart rate values was observed because the percentage of heart rate increased by 3.6% in the last 1,000-meter sector.

The article presents a case study that employed heart-rate monitoring and pacing strategy to describe the regulatory and physiological processes in an elite race-walker. Results indicated that a more even distribution of effort throughout a five-kilometer race might produce better results than a fast-start strategy.

Cardio-pump is a fitness group activity, which combines indoor cycling and resistance training performed with dumbbells and bars. The purpose of the present study was to evaluate the energy cost and aerobic requirement of a cardio-pump workout. Eight moderately trained individuals (4 males and 4 females, 35.8±14.3 years, 173.1±6.3 cm, 64.5±8.5 Kg), performed a cardio-pump lesson during which oxygen consumption (VO2), heart rate responses (HR) and blood lactate concentration La were measured to calculate its energy cost. The average intensity of the lesson was 80.9% HRmax and 64.7% VO2max, respectively. At the end of the lesson, Lapeak was 9.11±1.5mM (range: 5.12-16.20mM). The energy cost of the whole lesson was 380±91 kcal, including the extra cost of lactate. The highest energy cost (8.3±1.3 kcal/min) was recorded during muscular endurance phases involving large muscle masses (i.e., squats). In conclusion, cardio-pump shows high aerobic requirements and could be an optimal workout for those individuals who seek to train both cardiovascular and muscular fitness during the same class.

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.
