“…In addition, HR response can present problems when evaluating intensity during intermittent physical activity that utilizes both the aerobic and anaerobic energy systems. 19,20 Thus, although HR-based methods provide objective measures of ITL, they may not be practical for dance. An alternative to HR-based methods is session rate of perceived exertion (session-RPE) developed by Foster and colleagues.…”

OBJECTIVE: The session rating of perceived exertion (session-RPE) is a practical and non-invasive method that allows a quantification of internal training load (ITL) in individual and team sports. As yet, no study has investigated its construct validity in dance. This study examines the convergent validity between the session-RPE method and an objective heart rate (HR)-based method of quantifying the similar ITL in vocational dance students during professional dance training. METHODS: Ten dance students (4 male, 20±1.16 yrs; 6 female, 20±0.52 yrs) participated in this study. During a normal week of training, session-RPE and HR data were recorded in 96 individual sessions. HR data were analysed using Edwards-TL method. Correlation analysis was used to evaluate the convergent validity between the session-RPE and Edwards-TL methods for assessing ITL in a variety of training modes (contemporary, ballet, and rehearsal). RESULTS: The overall correlation between individual session-RPE and Edwards-TL was r=0.72, p<0.0001, suggesting there was a statistically significantly strong positive relationship between session-RPE and Edwards-TL. This trend was observed across all the training modes: rehearsal sessions (r=0.74, p=0.001), contemporary (r=0.60, p=0.001), and ballet (r=0.46, p=0.018) sessions. CONCLUSIONS: This study shows that session-RPE can be considered as a valid method to assess ITL for vocational dance students, and that notably there is some variation between session-RPE and HR-based TL in different dance activities.

“…The HR of two of our subjects was monitored by a Polar heart rate meter during an off-road competition exceeding 7 hours. Knowing their HR versus power linear relationship from our experiments, the power developed during the race may be grossly estimated [6]. The mean and maximum estimated power should be close, and probably inferior, to 217 and 243 W for one subject and 204 and 255 W for the other.…”

Energy Cost of Riding Bicycles with Shock Absorption Systems on a Flat Surface

Bike shock absorption systems reduce the energy variation induced by terrain irregularities, leading to a greater comfort. However, they may also induce an increase in energy expenditure for the rider. More specifically, cross-country racers claim that rear shock absorption systems generate significant energy loss. The energy losses caused by such systems may be divided in terrain-induced or rider-induced. This study aims at evaluating the rider-induced energy loss of modern suspended bicycles riding on a flat surface. Twelve experienced competitive racers underwent three multistage gradational tests (50 to 250 W) on a cross-country bicycle mounted on an electromagnetically braked cycle ergometer. Three different tests were performed on a fully suspended bike, front suspended and non-suspended bicycle, respectively. The suspension mode has no significant effect on VO2. The relative difference of VO2 between the front-suspended or full-suspended bike and the rigid bike reaches a non significant maximum of only 3%. The claims of many competitors who still prefer front shock absorption systems could be related to a possible significant energy loss that could be present at powers superior to 250 W or when they stand on the pedals. It could also be generated by terrain-induced energy loss.

“…Heart rate is an efficient and proven parameter which is helpful in designing training exercise loads [67]. More over, Lothian & Farrally [68] established that heart rate is a good intermediary parameter determining maximal oxygen uptake (VO 2 max). However, the authors did not show a correlation between VO 2 max and the activity of female field hockey players during a match.…”

Purpose. Using databases available on the Internet, the number of scientific papers on the subject of field hockey were examined. Basic procedures. As a result, 208 scientific studies covering the fields of biochemistry, physiology, sport injuries, psychology and tactics were found, which were published within the last 50 years (from 1960 to 2010). Despite the popularity of field hockey and its status as an Olympic sport, the number of scientific studies which focused on field hockey was much smaller when compared to the amount of publications on other team sports, such as soccer, basketball, or baseball. Main findings. It was found that the greatest number of pub lications (61.06%) originated from five English-speaking countries (UK, USA, Canada, Australia, and New Zealand), with the majority focusing on sport psychology, injuries and biochemistry. What was discovered was that the vast majority of scientific studies used field hockey merely as a reference point in comparison to other team sports. Conclusions. The varying topic diversity of the scientific stud ies found among the databases significantly hinders an effective comparison of findings, especially considering that most of the studies focused on only a few selected aspects of the problem matter and were chiefly small sample studies, nor were they repeated.
