“…In this work, we have identified variables associated with race time in the half-marathon through both laboratory assessment and the Cooper test. In the literature, there were several studies on different performance determinants in middle- and long-distance runners, such as anthropometric variables (Arrese and Ostáriz, 2006; Knechtle et al, 2010, 2014; Friedrich et al, 2014), variables related to training load (Ramsbottom et al, 1987; Knechtle et al, 2011a; Balsalobre-Fernández et al, 2014) as well as physiological variables (Roecker et al, 1998; Reilly et al, 2009; Rabadán et al, 2011; Ronconi and Alvero-Cruz, 2011; Gómez-Molina et al, 2017; Støa et al, 2010), which have associations with half-marathon performance.…”

“…Thus, the finish time in cross-country races has been associated with a high percentage of oxygen consumption (Loftin et al, 2007), as well as with blood lactate accumulation (Loftin et al, 2007), lactate threshold (Mujika et al, 2000), ventilatory threshold, or race economy (speed reached for a given oxygen consumption) (Amann et al, 2004; Saunders et al, 2004; Lucia et al, 2006; Støren et al, 2008; Santos-Concejero et al, 2017). However, it appears that the maximal speed achieved in the laboratory tests is the variable most closely associated with sports performance, regardless of the duration of the test (Noakes et al, 1990; Knechtle et al, 2011a; Ronconi and Alvero-Cruz, 2011).…”

This study compared the ability to predict performance in half-marathon races through physiological variables obtained in a laboratory test and performance variables obtained in the Cooper field test. Twenty-three participants (age: 41.6 ± 7.6 years, weight: 70.4 ± 8.1 kg, and height: 172.5 ± 6.3 cm) underwent body composition assessment and performed a maximum incremental graded exercise laboratory test to evaluate maximum aerobic power and associated cardiorespiratory and metabolic variables. Cooper’s original protocol was performed on an athletic track and the variables recorded were covered distance, rating of perceived exertion, and maximum heart rate. The week following the Cooper test, all participants completed a half-marathon race at the maximum possible speed. The associations between the laboratory and field tests and the final time of the test were used to select the predictive variables included in a stepwise multiple regression analysis, which used the race time in the half marathon as the dependent variable and the laboratory variables or field tests as independent variables. Subsequently, a concordance analysis was carried out between the estimated and actual times through the Bland-Altman procedure. Significant correlations were found between the time in the half marathon and the distance in the Cooper test (r = −0.93; p < 0.001), body weight (r = 0.40; p < 0.04), velocity at ventilatory threshold 1, (r = −0.72; p < 0.0001), speed reached at maximum oxygen consumption (vVO2max), (r = −0.84; p < 0.0001), oxygen consumption at ventilatory threshold 2 (VO2VT2) (r = −0.79; p < 0.0001), and VO2max (r = −0.64; p < 0.05). The distance covered in the Cooper test was the best predictor of time in the half-marathon, and might predicted by the equation: Race time (min) = 201.26 – 0.03433 (Cooper test in m) (R2 = 0.873, SEE: 3.78 min). In the laboratory model, vVO2max, and body weight presented an R2 = 0.77, SEE 5.28 min. predicted by equation: Race time (min) = 156.7177 – 4.7194 (vVO2max) – 0.3435 (Weight). Concordance analysis showed no differences between the times predicted in the models the and actual times. The data indicated a high predictive power of half marathon race time both from the distance in the Cooper test and vVO2max in the laboratory. However, the variable associated with the Cooper test had better predictive ability than the treadmill test variables. Finally, it is important to note that these data may only be extrapolated to recreational male runners.

“…Duathlon is a high-intensity cyclic modality composed of running-cycling--running. One of the official distances in competitions is sprint, which consists of 5 km of running, followed by 20 km of cycling and another 2.5 km of running [1,2], which depends mostly on the manifestation of skills such as anaerobic endurance, strength, speed, and coordination [3]. This modality is practiced by athletes of various levels around the world [4], which increases the need for an understanding of the organic responses, especially during competition.…”

Introdução: A termografia contribui para detectar alterações fisiológicas causadas pelo esporte com o uso da temperatura da pele. Objetivo: Verificar diferenças na temperatura dos membros inferiores após uma competição de duathlon sprint. Métodos: Participaram sete duatletas (37 ± 8 anos, 72,3 ± 6 kg, 15,7 ± 3% e 171 ± 7 cm). Um termovisor FLIR® E8 (sensibilidade ≤ 0,06 °C) foi usado para coletar imagens das regiões de interesse: quadríceps, tibiais, isquiotibiais e panturrilhas antes (M0), imediatamente após (M1) e 10 minutos após a competição (M2). Resultados: Os resultados indicam sensível diminuição da temperatura de quadríceps, tibiais e isquiotibiais em M1 comparado a M0. Em M2, é observada uma temperatura maior que em M0 e M1 em quadríceps, tibiais e panturrilhas. A competição resultou em uma sensível diminuição, seguida de um aumento da temperatura em todas as regiões, exceto nas panturrilhas, e não causou assimetrias entre membros dominantes e não dominantes. Conclusão: A termografia pode ser utilizada na análise de duatletas e assimetria entre membros, podendo auxiliar no planejamento e organização do treinamento dessa modalidade.

“…response of the heart to physical exercise; electrocardiographic analysis (Balady et al, 2010) is used for the diagnosis, monitoring and prevention of ischemic heart disease (McSweeney et al, 2016) and monitoring the performance of athletes (Ronconi & Alvero-Cruz, 2011). In addition, by incorporating spirometric analysis, through the study of respiratory gases, these practitioners will obtain information on the adaptation to exercise that can be evaluated regarding the performance and planning of training (Arós et al, 2000).…”

The goal of this research is the Analyse the influence of age, experience and relative fat mass (RFM) on physical performance in women practising Nordic Walking during maximal treadmill exercise testing. The population was formed of 20 women, who underwent a maximum stress test with continuous electrocardiographic recording. The Bruce protocol on the ramp was modified with progressive increases in speed and incline. In addition, we measured their height, weight, and waist. A study of exhaled gases was carried out. Our population has an average RFM of 39.8±2.9. Experience subjects reach higher levels of intensity during the exercise, with a variable speed of 6.4±0.9 km/h, compared to newcomers at 5.6±0.7 km/h (p<0.05). We observe that with higher RFM, higher body mass index (BMI) and waist size index, there is a lower oxygen consumption (VO2) and metabolic equivalent (METS) (p<0.05). Likewise, a longer time increases both VO2 and METS (p<0.05). The results suggest that the indexes and anthropometric relationships RFM, BMI, and waist-size index (WSI) influence performance in women practising Nordic Walking. In addition, previous experience in this discipline is also an influential factor in the intensity of the exercise.
