The amount of blood pumped by the heart in litres per minute. Thus, cardiac output is also increased i.e. This is in part due again to that left ventricle mass and its increased ability to contract. Stroke volume increases – stroke volume, put basically, is the volume of blood your heart pumps with each beat, obviously the higher this is the more oxygen rich blood being delivered! Trained individuals can have stroke volumes in excess of 180ml/min during exercise. Through this the filling capacity of the left ventricle is increased meaning more blood can get in! Increase in heart size – this is due to the left ventricle (a chamber in the heart muscle) wall undergoing hypertrophy like any other muscle in the body and becoming thicker. So, what are some of the common adaptations to endurance training if the athlete is producing power over extended time periods? Here we’re talking about cardiovascular (your heart and veins), respiratory (lungs) and metabolic (fuel usage) gains.
As an endurance athlete you are predominantly required to produce power over extended periods of time or distances usually with a high reliance on aerobic (with oxygen) metabolism. Clinicians who treat male patients for sexual disorders and/or council couples on infertility issues should consider the degree of endurance exercise training a man is performing as a potential complicating factor.Endurance sport is characterised by lactate threshold, VO2 Max and economy 1. Participants with the shorter (OR = 4.1, 95% CI = 1.6-10.0) and mid-range training durations (OR = 2.5, 95% CI = 1.3-4.8) at their current intensity also had greater odds of high/normal libido score than those with a greatest duration.Įxposure to higher levels of chronic intense and greater durations of endurance training on a regular basis is significantly associated with a decreased libido scores in men. Participants with the lowest (OR = 6.9, 95% confidence interval = 2.6-17.9) and mid-range training intensities (OR = 2.8, 95% CI = 1.4-5.3) had greater odds of high/normal libido state than those with the highest training intensity. In the multivariate model, training intensity (P < 0.0001) and duration (P < 0.002) components were the most significantly associated with libido group designation (high/normal vs low). Odds ratio (OR) values were calculated to examine group categorization.Īge, training intensity, and training duration of participants had significant (P < 0.02) univariate relationships, with libido scores, and were thus included in the multivariate model. The high and normal categories were combined to form a high/normal score group, and the low category formed a low score group. Three evidence-based categories were created for the primary outcome of total libido score and low, normal, and high-response category sets. The questionnaire was based on preexisting validated questionnaires and was used to assess elements of physical characteristics, exercise training habits, and libido of participants (n = 1077). This article aimed to study the associations between aspects of endurance exercise training and sexual libido in healthy men using a cross-sectional online survey study design.Ī developed online survey questionnaire was used.
