Abstract: The aim of the present study was to investigate the effects of resistance training on skeletal muscle lipid content, liver lipid content, heart lipid content, fat depots, and lipid profile in ovariectomized rats. Wistar adult female rats were divided into 4 groups (n = 10 per group): sedentary (Sed-Intact), sedentary ovariectomized (Sed-Ovx), strength trained (ChronicEx-intact), and strength trained ovariectomized (ChronicEx-Ovx). A 12-week strength-training period was used, during which the animals climbed a … Show more

“…During subsequent ladder climbs, an additional 30 g load was added for up to five attempts until a new MCL was determined. The resistance training protocol was adapted from Hornberger and Farrar 22 , according to the needs of the current research, and was already done by our group 3,9,11,20,23 .…”

“…Sin embargo, el RT puede ser tan efectivo como el ejercicio de resistencia cardiorrespiratoria en personas con dislipemia (99), gracias a la capacidad reductora de los niveles de LDL y triglicéridos y de incrementar los niveles de HDL de este tipo de ejercicio (100). Un estudio realizado en mujeres obesas, que tuvo por objetivo comparar el efecto sobre el perfil lipídico del RT (series de 10 repeticiones al 50-100% 1 RM) con respecto al de resistencia cardiorrespiratoria (intensidad del 70% frecuencia cardiaca máxima [FC máx ]) durante 6 semanas, comprobó que ambos entrenamientos produjeron disminuciones en los niveles de LDL y triglicéridos, al tiempo que mejoraron los niveles de HDL (99). Al comparar ambos grupos se vio que las mejoras no fueron estadísticamente diferentes a excepción del HDL, que se incrementó en mayor medida en el grupo de entrenamiento de resistencia cardiorrespiratoria (99).…”

“…Frisch and Sumida (1999) observed that strength training for ten weeks did not affect the serum TC, LDL, or HDL in the rats. On the other hand, Leite et al (2009) observed that a similar type of RE for 12 weeks significantly increased the serum concentration of HDL and reduced those of LDL and very low density lipoprotein cholesterol (VLDL). In a metaanalysis of randomized controlled human trials, Kelley and Kelley (2009) concluded that longterm RE resulted in decreased blood concentrations of TC, LDL, and triglycerides and increased concentrations of HDL.…”

“…In this context, aerobic exercise has been considered the most preventive type of exercise (Tanasescu et al 2002;Williams et al 2007). Although resistance exercise (RE), such as weight-lifting (WL), may reduce multiple CVD risk factors (Hurley et al 1998;Miller et al 1994), its effects on lipid metabolism remain controversial in both animal and human studies (Williams et al 2007;Frisch and Sumida 1999;Leite et al 2009;Kelley and Kelley 2009;Sallinen et al 2007). Frisch and Sumida (1999) observed that strength training for ten weeks did not affect the serum TC, LDL, or HDL in the rats.…”
