“…Although the effects of supplements are usually investigated in isolation, it is very common to combine different ergogenic aids in the sports field in order to achieve maximum performance [39][40][41]. In this sense, it could be considered that the effect of this combination might be better than individual intake.…”

Creatine monohydrate (CrM) and β-hydroxy β-methylbutyrate (HMB) are widely studied ergogenic aids. However, both supplements are usually studied in an isolated manner. The few studies that have investigated the effect of combining both supplements on exercise-induced muscle damage (EIMD) and hormone status have reported controversial results. Therefore, the main purpose of this study was to determine the effect and degree of potentiation of 10 weeks of CrM plus HMB supplementation on EIMD and anabolic/catabolic hormones. This study was a double-blind, placebo-controlled trial where participants (n = 28) were randomized into four different groups: placebo group (PLG; n = 7), CrM group (CrMG; 0.04 g/kg/day of CrM; n = 7), HMB group (HMBG; 3 g/day of HMB; n = 7), and CrM-HMB group (CrM-HMBG; 0.04 g/kg/day of CrM plus 3 g/day of HMB; n = 7). Before (baseline, T1) and after 10 weeks of supplementation (T2), blood samples were collected from all rowers. There were no significant differences in the EIMD markers (aspartate aminotransferase, lactate dehydrogenase, and creatine kinase) among groups. However, we observed significant differences in CrM-HMBG with respect to PLG, CrMG, and HMBG on testosterone (p = 0.006; η2p = 0.454) and the testosterone/cortisol ratio (T/C; p = 0.032; η2p = 0.349). Moreover, we found a synergistic effect of combined supplementation on testosterone (CrM-HMBG = −63.85% vs. CrMG + HMBG = −37.89%) and T/C (CrM-HMBG = 680% vs. CrMG + HMBG = 57.68%) and an antagonistic effect on cortisol (CrM-HMBG = 131.55% vs. CrMG + HMBG = 389.99%). In summary, the combination of CrM plus HMB showed an increase in testosterone and T/C compared with the other groups after 10 weeks of supplementation. Moreover, this combination presented a synergistic effect on testosterone and T/C and an antagonistic effect on cortisol compared with the sum of individual or isolated supplementation.

“…Se ha confirmado que ciertas características físicas como la composición corporal, peso y talla pueden influir significativamente en los resultados deportivos (Duquet et al, 2001). El remo se caracteriza por ser un deporte de potencia y resistencia (Jürimäe et al, 2010;Jensen, 2011;Majumdar, Das, & Mandal, 2017), este deporte consiste en superar una distancia de 2000 metros oficiales (Boegman & Dziedzic, 2016;Majumdar et al), en un intervalo de tiempo que varía entre los 320 y 460 segundos (Bourgois et al, 2014;Majumdar et al). La competición se desarrolla en diferentes modalidades deportivas, en función del sexo y el peso del atleta, además del tipo de embarcación competitiva (Slater et al, 2014;Boegman & Dziedzic).…”

RESUMEN: El objetivo del estudio fue describir las características antropométricas y somatotipo de los seleccionados chilenos de remo. Se evaluaron a 21 deportistas (6 mujeres y 15 hombres) con edades promedio de 18,66 ± 2,58 años para las mujeres y de 22,06 ± 4,71 años para los hombres. El estudio se realizó previo al clasificatorio Panamericano Lima 2019, al momento de las evaluaciones, los deportistas se encontraban concentrados en el centro de entrenamiento olímpico (CEO) ubicado en Curauma en la región de Valparaíso en Chile. Las evaluaciones antropométricas se realizaron en base al perfil restringido de 25 variables propuesto por Ross & Kerr (1991), que permitió fraccionar la masa corporal en 5 componentes (tejidos: piel, residual, óseo, adiposo y muscular). Se midieron también la envergadura, la altura ilioespinal y los pliegues del bíceps y supracrestídeo, todas las medidas se realizaron en base al protocolo de marcaje y evaluación propuesto por ISAK. Se uso el método de Carter y Heath para calcular el somatotipo, describiendo los componentes de endomorfía, mesomorfía y ectomorfía respectivamente. Los resultados mostraron un porcentaje de grasa en hombres de 19,34 ± 1,59 % y en mujeres de 27,08 ± 3,6 % (p=0,003), la masa muscular de hombres fue de 52,69 ± 1,78 % y en mujeres de 45,68 ± 4,19 % (p=0,003), se apreció un somatotipo mesomorfo balanceado tanto en hombres (1,7-5,3-2,2) como mujeres (2,5-3,7-2,7). Se concluye que los seleccionados chilenos de remo presentan un alto desarrollo de masa muscular y un bajo porcentaje de masa grasa, además de un somatotipo mesomorfo balanceado.

“…The energy required for 2000 m indoor rowing is estimated to be 65 ± 75% aerobic and 25 ± 35% anaerobic [6]. However, other studies also suggest that anaerobic capacity only explains 10 ± 20% of the performance of trained rowers, while aerobic metabolism shows a contribution of 67-88% [7] and, because rowing performance is highly correlated with maximum oxygen uptake (VO2Max) [8,9], hence maximal oxygen uptake (VO2Max) is an important physiological parameter for rowing rowers. VO2Max is the variable with the largest correlation (r = 0.71) with rowing performance compared to other parameter correlations [10].…”

The purpose of this research is to predict the performance of 2000 meters indoor rowing using 100-meter test, 60s test and 6000-meter test. The sample used is 22 rowing athletes, consisting of 10 male lightweight athletes, 3 male heavy weight athletes, 7 female light weight athletes and 2 female heavyweight athletes aged around 19 ± 29 years old, who joined the Program Indonesia Emas. Participants give written approval before participating in this research. All experimental procedures are approved by the Executive Board of the Indonesian Rowing and Canoeing Association (PB PODSI). The test was performed with a physical test series developed by Danish Rowing, taking a standard of 21 Danish rowers. Rowing athletes participate in a series of physical tests conducted within 4 days, displaying all out performance for specified test types as well as the distance specified using Concept2, type C rowing ergometer. The results of this study is a prediction of 2000 meter power performance based on 100 meter test power performance, 60 second test and 6000 meter test. This study reflects an optimal physiological adaptation for rower performance. Rowers can use the same general training preparations, whether they are open classes or light classes, male or female. Dividing the training according to the endurance curve for each rower. If an oarsman does anaerobic tests poorly, he may have to do more strength training and power exercises. On the other hand, if an oarsman is too strong in relation to his aerobic endurance, he should focus on aerobic training. This research will be useful, because the trainer will get the profile data of each group or athletes that will be a reference for trainers in sorting out and choosing what physiological aspects should be a priority target in planning the exercises.
