Because jogging is a form of resistance exercise, it too can lead to healthy levels of testosterone. Like other forms of resistance training, pilates can result in a boost in testosterone if performed with the right technique and under the right intensity. While studies indicate that testosterone can be increased following short, intense swimming exercise, working out at maximal intensity may result in a decrease in testosterone. Scientists noted that testosterone levels spike immediately following resistance training. Limited information is available on the impact of exercise on adipokines and anti-Müllerian hormone, warranting further investigation. Studies in which the effects of the exercise intervention could be determined were included. Regular physical activity is recommended for women with PCOS to maintain a healthy weight and cardiovascular fitness. One study in 2016 that looked into progressive resistance training reported decreases in FAI of 0.82%. The same study published in the Frontiers of Psychology that proved the pros of cardio activity, also looked into resistance training for PCOS. ‘It can also help regulate your hormones and lower the increase you have in testosterone, which will soothe symptoms such as acne and hair growth – both of which are rooted in higher testosterone.’ A six-month study that involved cycling for 45 min three days per week at 60–70% VO2max yielded a decrease in FI and HOMA-IR, as well as an increase in GIR during a hyperinsulinemic-euglycemic clamp, with no changes reported in sex hormones, LH, or SHBG . In a three-month study, cycling for 30 min three days per week at 60–70% VO2max resulted in decreased fasting insulin (FI) levels, with no significant changes in the sex hormones, LH, or sex hormone binding globulin (SHBG) 84,85. Randomized controlled trials (RCTs) with aerobic exercise interventions in studies of women with PCOS included prescribed exercise on a motorized treadmill or cycling under the supervision of medical, athletic, or research personnel. Studies of aerobic exercise interventions in women with PCOS that included hormone outcomes measured are summarized in Table 2. The goals of this systematic review are to evaluate the study design and results of investigations of exercise on hormones in women with PCOS, to use this information to guide therapeutic recommendations for women with the disorder, and to highlight the need for future studies. The study utilized pre- and post-intervention biochemical measurements, including SHBG and testosterone levels, to analyze results. The findings indicate that testosterone levels decreased significantly in the Pilates exercise group after the intervention period. In addition, according to one study, minimizing the length of rest periods between sets during weightlifting produced an increased testosterone effect. There is no increase in basal or resting post-exercise serum testosterone. When exercise does increase testosterone, it is temporary. Resistance and high-intensity interval training (HIIT) elicit a temporary testosterone boost. The impact of yoga on insulin sensitivity and androgens appears promising and requires further study.
