Finally, our focus on cortisol and testosterone does not preclude a role for other metabolic, enzymatic or cardiovascular factors 6, 20, 22. It is noteworthy that capillary blood measures of cortisol and testosterone, taken from our cohort under the same training conditions, did rise slightly at T3 (vs. T1) . Emphasizing this point, male swimmers showed a decrease in testosterone concentration across the season, relative to off-season values that, we argue, represents a true baseline in androgen activity. Only stress responded to training, decreasing at T2 and T3 (vs. T1) in female swimmers. Shanna Swan, a professor of preventive medicine at Mt. Sinai School of Medicine, finds the study intriguing but unconvincing due to factors such as the different hormone effects after swimming in indoor and outdoor pools, which tend to have roughly similar chlorination treatment. These data indicated that plasma testosterone concentration can decrease in male swimmers during intense endurance training; this alteration does not affect wholebody insulin action. Older swimmers need to be particularly mindful of nutrition, recovery, and training volume to maintain healthy testosterone levels. Moderate-intensity swimming, especially in individuals who are previously sedentary, can improve overall health and potentially increase testosterone levels. The body responds to this stress by releasing hormones, including testosterone, cortisol, and growth hormone. Speculatively, these outcomes could be viewed as a pre-training preparatory response, at least for male swimmers, given situational (e.g., training phase) or contextual cues (e.g., stress / sleep changes arising from a recent performance). Interestingly, a psychological stressor applied in a similar epoch (4–6 pm) was also effective in acutely elevating cortisol (31%) and testosterone (20%) concentrations in elite swimmers . These hormones could work in a cooperative manner to maintain homeostasis, especially under stress , perhaps explaining why this linkage was limited to the high-volume training phase. This association seems counterintuitive given the assigned catabolic and anabolic roles of cortisol and testosterone, respectively 32, 39. There is broad evidence of positive testosterone and cortisol relationships in athletes and non-athletes 35, 36, 37, 38. During sleep, the body repairs itself and produces hormones. Sleep is crucial for hormone regulation, including testosterone. Regular testosterone testing is generally recommended for athletes experiencing symptoms of low testosterone, or those engaging in very high-volume, high-intensity training. Swimming, by helping to reduce body fat, can indirectly contribute to improved testosterone production. Does age play a role in how swimming affects testosterone? Distance swimming, on the other hand, is more likely to require careful management of nutrition and recovery to prevent potential suppression. Swimming is generally considered an excellent form of exercise, and indoor swimming is common, especially in winter. Cycling also prevents testosterone production by causing a temperature dysregulation within the scrotal sac due to the pressure mounted on it. To avoid stress in your everyday life, you should adopt a healthy lifestyle that creates a balance between rest and work. Research has proven that these supplements are good testosterone hormone boosters, especially in the elderly (source). Your everyday meals are not enough to give your body the boost it needs to produce more testosterone. Food is everything especially when it comes down to the production of body hormones. Cycling decreases testosterone levels because it is a high endurance exercise that causes stress and rapid production of cortisol, a hormone that dampens testosterone production.

Our first hypothesis was that some hormonal changes (i.e., increase in baseline cortisol and testosterone levels) would occur from T1 to T3, coinciding with less stress and better recovery (i.e., improved willingness to train and sleep quality). This includes psychological processes (e.g., motivation to train, stress, sleep quality, recovery) linked to daily changes or differences in athlete cortisol and/or testosterone levels 7, 16, 17, 18. Based on these previous findings and the outcomes in this study, it is suggested that moderate swimming exercise can inhibit the pro-inflammatory cytokines by reducing oxidative stress, which can promote testosterone synthesis by enhancing anti-inflammatory cytokine.

While it's not a miracle cure for low testosterone, swimming can positively influence hormone levels, especially when done regularly and with moderate to high intensity. The health benefits of swimming also include improved posture, flexibility, and muscle tone, especially in areas that are often neglected in traditional gym routines. The specific swimming stroke is unlikely to have a significant impact on testosterone levels. Exposure to cold water can initially cause a temporary increase in testosterone as the body responds to the stress.
