Concurrent Validity of the Armour39 Heart Rate Monitor Strap

New technology offers potential advantages in physically demanding environments where convenience and comfort are important and accurate and reliable data collection is challenging. Nevertheless, it is important to validate the accuracy and reliability of such biological monitoring systems (BMS) before they are adopted. The purpose of this investigation was to assess the concurrent validity of a new heart rate monitor across a range of exercise intensities and with a large and diverse group of male subjects in a large cohort with diverse physical fitness characteristics. Seventy-five men (age, 23 [+ or -] 4 years; height, 181 [+ or -] 8 cm; body mass, 83 [+ or -] 12 kg; estimated [[??]O.sub.2]peak, 3.16 [+ or -] 0.63 [L x [min.sup.-1]]) volunteered and completed a graded cycle ergometer exercise protocol while heart rate was continuously monitored before, during, and after exercise with the new device (Armour39) and the gold standard (electrocardiogram). The 2-minute stages included sitting, standing, and cycling with 35 W increments until volitional fatigue. The coefficient of determination between mean heart rate values at each stage was [R.sup.2] = 0.99, whereas Pearson correlations (r) at each stage were [greater than or equal to] 0.99. Heart rates during exercise were typically within 1 beat of each other. The Armour39 BMS, therefore, is an acceptable means for the valid and reliable determination of heart rate under various bodily positions and levels of exertion, including maximal exercise intensity

Landscape and Culture - Cross-linguistic Perspectives

The relationship between landscape and culture seen through language is an exciting and increasingly explored area. This ground-breaking book contributes to the linguistic examination of both cross-cultural variation and unifying elements in geographical categorization. The study focuses on the contrastive lexical semantics of certain landscape words in a number of languages. The aim is to show how geographical vocabulary sheds light on the culturally and historically shaped ways people see and think about the land around them. Notably, the study presents landscape concepts as anchored in a human-centred perspective, based on our cognition, vision, and experience in places. The Natural Semantic Metalanguage (NSM) approach allows an analysis of meaning which is both fine-grained and transparent. The book is aimed, first of all, at scholars and students of linguistics. Yet it will also be of interest to researchers in geography, environmental studies, anthropology, cultural studies, Australian Studies, and Australian Aboriginal Studies because of the book’s cultural take
