The Effects of Aerobic Versus Resistance Training on Cardiovascular Fitness in Obese Sedentary Females

Abstract

Purpose: The present study was designed to evaluate the effects of aerobic and strength training on cardiac variables such as blood pressure, heart rate (HR), and metabolic parameters like cholesterol, high density lipoprotein (HDL), triglycerides and anthropometric parameters of obese women of Punjab. Methods:This study was performed as an experimental study, in which subjects were randomly selected. There were thirty obese women, aged between 35-45yrs with body mass index (BMI) of above 30. Subjects were grouped into control (n=10), aerobic training (n=10) and resistance training (n=10). Aerobic training was given for three days a week at 60-70% of maximum HR for 6 weeks. Resistance training (Delorme and Watkins Technique) was given for alternate days for 6 weeks. HR and blood pressure were measured before and after the exercise. Recovery HR was also measured. Results Conclusion:Aerobic training is more beneficial and can be used as a preventive measure in patients who are at risk of developing cardiovascular diseases due to obesity.

A systematic review to determine reliability and usefulness of the field-based test batteries for the assessment of physical fitness in adolescents – The ASSO Project

“…It is known, in fact, that over the last decades the overall fitness level [101] and in particular, cardio-respiratory fitness of the general population has decreased [102] leading to an increase in health conditions related to physical inactivity [103,104]. Cardio-respiratory fitness is known to have positive associations with high-density lipoproteins, systolic blood pressure, diastolic blood pressure [105,106], BMI, measures of body fat [107], and arterial stiffness [108].…”

“…(27) Furthermore, a previous study has indicated that mechanisms by which aerobic exercise lowers BP partly involves the effects of epinephrine and norepinephrine. (28) Aerobic exercise reduces the blood level of norepinephrine which limits vasoconstriction of the arterioles and decreases the peripheral resistance to BP, hence causing reductions in BP. (28) Another possible reason for the reductions in SBP in this study could be that regular exercise also lowers HR due to activation of the parasympathetic division of the autonomic nervous system, which in turn allows the ventricles more time to fill with blood, ensuring adequate oxygen and nutrient delivery.…”

“…Moreover, aerobic training increases energy expenditure by activation of lipolysis and affects the reduction of body fat percentage. (28) A study conducted on postmenopausal women further indicates that reductions in weight improves the physical and mental HRQoL domains and leads to a positive change in self-perceived health status. (37) Similarly, significant reductions in waist circumference were also observed among this group of participants.…”

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).…”
