Effect of intensive resistance training on isotonic exercise Doppler indexes of left ventricular systolic function

Cardiovascular adaptations to 4 and 12 months of football or strength training in 65‐ to 75‐year‐old untrained men

“…Surprisingly, we also observed positive effects on LVEF and global longitudinal two‐dimensional strain in STG, which is in accordance with some, but not all, observations in younger athletes (Poulsen et al., ; Spence et al., ). Indeed, the finding that strength training also improved LV systolic function adds importantly to the literature in this area of research, but the mechanisms underlying improved LV systolic function observed in both training groups clearly warrant further study (Delagardelle et al., ; Fisman et al., ).…”

“…Exercise training in the elderly is associated with favorable cardiovascular adaptations, but available studies have mainly focused on the effects of endurance exercises and strength training (Haykowsky et al., ; Fisman et al., ; Maeda et al., ; Andersen et al., ; Fujimoto et al., ). For elderly individuals, it may be difficult to find motivation to adhere to individual exercise training, and other sports, such as team sports, could serve as an attractive alternative training modality with potential of similar favorable cardiovascular adaptations and be associated with increased adherence.…”

“…Exercise training in the elderly is associated with favorable cardiovascular adaptations, but available studies have mainly focused on the effects of endurance exercises and strength training (Haykowsky et al, 2000;Fisman et al, 2002;Maeda et al, 2006;Andersen et al, with potential of similar favorable cardiovascular adaptations and be associated with increased adherence. Football intervention studies carried out by our research group have demonstrated that football training is akin to high-intensity interval training and is capable of improving cardiovascular risk factors for young and middle-aged men, such as hypertension, obesity, and low maximum oxygen uptake, and ameliorating circulating lipid levels (Krustrup et al, 2010(Krustrup et al, , 2013Schmidt et al, 2013b).…”

“…Importantly, increased muscle strength is associated with a reduction in the risk of CVD and all‐cause mortality, and strength training appears to be a feasible physical activity for aging people (Artero et al., ). During strength training, a large increase in systolic blood pressure (BP) often occurs, which increases myocardial wall stress and may lead to LV hypertrophy; although strength training may also increase LV systolic function, knowledge about cardiovascular adaptations to strength training in elderly men is very limited (Fisman et al., ; Poulsen et al., ). The aim of the present study was therefore to examine the cardiovascular effects of a 1‐year intervention consisting of either football training or strength training in elderly, healthy untrained men as determined by comprehensive echocardiography, including TDI and two‐dimensional global strain analysis, and measurements of peripheral microvascular function and cardiorespiratory fitness, respectively.…”

The toll of the gridiron: damage‐associated molecular patterns and hypertension in American football

“…In contrast, weightlifting, may be more comparable to football in terms of duration and intensity, and it is a noncontact activity that football players frequently engage in. Weightlifting alone does not cause long‐term elevation in blood pressure (46‐49), in contrast to sumo wrestling (50) and soccer (51), both of which are contact sports. Although knowing whether DAMPs are increased as a result of participation in different sports is of interest, it would be more valuable to clarify the point at which the damage associated with physical activities overwhelms the presumed benefits and contributes to the development of chronic disease.…”
