On the flip side, endurance or long-distance running might have the opposite effect. This can be likened to the body’s way of coping with the demands of the intense exercise. Let’s explore the two main types of running and their impact on testosterone. However, the intensity and duration of the run play a significant role in determining how much testosterone is produced. From cardiovascular benefits to mental health improvements, the pros of running are well-documented.
After recording the test data, the ventilatory thresholds were determined according to the three-phase model to monitor training . A running test on a treadmill (Powerjoc, UK) equipped with a gas analyzer (Metamax, Cortex Biophysik Gmbh, Germany) and a Polar pulsometer (Polar Vantage M, Norway) was used to evaluate the maximum oxygen uptake (VO2 max). Skinfold thicknesses were measured with a Harpenden caliper (Holtain Skinfold Caliper, Crosswell, UK) and converted to % of body fat using the equations of Jackson and Pollock . Fat mass and fat-free mass content was estimated from the sum of 6 skinfolds (∑6) (abdominal, suprailiac, tricipital and subscapularis, thigh and calf). Body height was measured to the nearest 0.1 cm using a wall-mounted stadiometer (Seca©, Hamburg, Germany), and body weight was measured to the nearest 0.01 kg using calibrated electronic digital scales, (Seca©, Hamburg, Germany) in barefoot conditions. Subjects reported to the laboratory after an overnight fast and had to abstain from hard training and/or competition for at least 72 h before testing.
However, other studies were unable to distinguish differences in basal T-Testo between lifelong trained and sedentary elderly men (Hayes et al. and Tissandier et al. ). Hackney et al. reported that endurance trained men had lower T-Testo than sedentary men. Safarinejad et al. conducted a randomized trial of middle-age men undergoing intensive treadmill running. The 5-year-long NHANES study included 738 participants, who were classified in three tertiles, based on metabolic equivalent of task (MET) score, and according to the compendium of physical activities.
In endurance activities, its blood values increase, as its catabolic function contributes to maintaining adequate energy levels through protein degradation, hydrolysis of triglycerides and even adding additional energy from carbohydrates through gluconeogenesis in the liver . Endurance athletes modulate the volume and intensity of their constant training throughout the sports season in order to produce adaptations and achieve their best performance in previously established competitive periods . The aim of this study was to determine the possible changes in plasma of several hormones such as Luteinizing Hormone, Testosterone, Cortisol and Insulin in endurance runners during the sports season. Their hobby or sport forces an adaptation to make them better runners, but this same adaptation tanks their testosterone levels. Shorter, more strategic running sessions combined with resistance training may provide the cardiovascular benefits without sacrificing testosterone.
Running is one of the most popular forms of exercise—praised for its physical, mental, and cardiovascular benefits.
Scientific evidence supports these potential advantages, making testosterone an attractive option for some athletes looking to improve their performance. Research published in the "American Journal of Physiology" showed that testosterone administration helped reduce muscle damage and inflammation after intense exercise. Several studies have investigated the effects of testosterone supplementation on athletic performance. This means runners can train more frequently and with greater intensity, leading to better performance over time. For runners, having more muscle mass can lead to improved strength and power. This can help to increase muscle mass and strength, enhance recovery after workouts, and improve overall stamina.
Endurance or aerobic exercise refers to any type of cardiovascular conditioning where breathing and heart rates increase for a sustained period of time. Lastly, within the scope of this work, we analyzed only studies conducted in healthy men. The majority of the work presents the data on either serum or plasma testosterone, while some report on the salivatory hormone. However, analysis of the existing literature demonstrates a large degree of inter-individual and inter-study variability in hormonal changes during exercise. They’re right that Low T might be the problem, especially if lifestyle changes like running aren’t boosting testosterone and helping you maintain your weight. (Read our comprehensive guide to Testosterone and Exercise for the answers to the most common questions related to training and testosterone.) These results indicate that the sprint exercise, a form of HIIT (High Intensity Interval Training) resulted in an anabolic or muscle-building state, similar to weight lifting. /FFM. Nutritional intake of the athletes during the season is shown in Table 3. Simple linear regression analysis was conducted to examine the associations between hormones and km trained per week. All variables used in the study were checked for normality of distribution before the analyses (Kolmogorov–Smirnov tests). The hormone determination was carried out using the ELISA (enzyme-linked immunosorbent assay) with an ER-500 (Sinnowa, Germany), using the commercial tests for I, C, T and LH.|More red blood cells mean better oxygen delivery to your muscles during exercise. While long-distance runners don't need bulky muscles, having well-developed muscle fibers can improve overall performance. Muscle mass is crucial for runners because stronger muscles can generate more power and speed. When you exercise, especially with activities like running, your muscles undergo small tears. Testosterone is a critical hormone that significantly impacts the body's ability to perform physical activities, including running.}
Your blood panels provide objective data about compound effects, allowing evidence-based decisions about dosing, duration, and health interventions. Avoid intense training hours before blood draws for accurate results. But there can be serious side effects, including an increased risk of prostate cancer and liver damage, and even aggression in cases where too much testosterone is prescribed. It has been widely reported that training improves insulin sensitivity , which can be considered a positive adaptation produced in runners to enhance the use of fatty acids as fuel . During prolonged training, the I level decreases because the catecholamine increase inhibits the I secretion . Reduced insulin levels have been observed in energy-deficient athletes . Other study reported a significantly lowered maximal exercise-induced level of I .
