“…The increase in cortisol levels observed in some studies was greater when exercise was performed in the morning rather than the afternoon and was linearly related to exercise intensity ( 66 , 102 ). The decrease in levels following exercise observed in other studies was more evident in premenopausal than postmenopausal women and was independent of exercise type and intensity ( 72 , 79 , 104 ). No prospective cohort studies that investigated the effect of physical activity on cortisol were identified.…”

“…Although there was no difference between pre- and postmenopausal women in acute responses to prolonged endurance exercise (a 50–100 km run; ref. 71 ), acute changes in estradiol levels were more evident in premenopausal women following strength training ( 72 , 104 ).…”

“…In nonrandomized interventions, there was no change in resting testosterone levels after ongoing exercise in 10 of 12 studies. In response to acute exercise, testosterone levels increased briefly following exercise then returned to baseline following recovery in some ( 68 , 70 , 72 , 84 , 85 , 91 , 98 , 99 , 101 , 104 ), but not all studies ( 65 , 90 , 93 , 96 , 100 , 108 , 109 ). The increase was evident in response to both aerobic and strength exercise and during both phases of the menstrual cycle.…”

“…Little evidence of a change in cortisol was evident from a meta-analysis of RCTs (5 studies, n = 328; SMD = 0.08; 95% CI = −0.19, 0.35; I 2 = 26%). Following a single session of exercise, some studies documented no change ( 58 , 59 , 88 , 100 ), some documented an increase in cortisol during or immediately following exercise ( 66 , 68 , 74 , 82 , 90 , 103 , 105 , 106 ), and others identified a decrease in cortisol compared with baseline at the conclusion of exercise or following a recovery period ( 70 , 72 , 79 , 85 , 87 , 92 , 96 , 104 ). The increase in cortisol levels observed in some studies was greater when exercise was performed in the morning rather than the afternoon and was linearly related to exercise intensity ( 66 , 102 ).…”

The effect of physical activity on breast cancer risk may be partly mediated by sex steroid hormones. This review synthesized and appraised the evidence for an effect of physical activity on sex steroid hormones. Systematic searches were performed using MEDLINE (Ovid), EMBASE (Ovid), and SPORTDiscus to identify experimental studies and prospective cohort studies that examined physical activity and estrogens, progestins, and/or androgens, as well as sex hormone binding globulin (SHBG) and glucocorticoids in pre- and postmenopausal women. Meta-analyses were performed to generate effect estimates. Risk of bias was assessed, and the GRADE system was used to appraise quality of the evidence. Twenty-eight randomized controlled trials (RCT), 81 nonrandomized interventions, and six observational studies were included. Estrogens, progesterone, and androgens mostly decreased, and SHBG increased, in response to physical activity. Effect sizes were small, and evidence quality was graded moderate or high for each outcome. Reductions in select sex steroid hormones following exercise supports the biological plausibility of the first part of the physical activity–sex hormone–breast cancer pathway. The confirmed effect of physical activity on decreasing circulating sex steroid hormones supports its causal role in preventing breast cancer.

“…Five studies used a leg press device as a testing device only [11,12] or in combination for testing and determining the acute effects after a strength loading protocol [11,[13][14][15]. In the study of Sedliak et al [11], leg presses were used to test the bilateral MVC force before and after the training program.…”

Background: The purpose of this scoping review was to analyze the evidence of acute and long-term effects of the application of leg-press strength training with or without serial stretch-loading stimuli on various biomechanical and physiological outcomes. Methods: This review was performed in accordance with PRISMA for Scoping Reviews recommendations, and two researchers independently searched the following databases: PubMed, Web of Science, Scopus, ScienceDirect, ProQuest, Cochrane, and Google Scholar. All studies that used unique leg-press device for testing, acute responses and long-term adaptation were included in this review, irrespective of the measured outcomes. A total of 13 studies were included in this review, with 5 focused on the testing capabilities of the device and acute training responses and 8 focused on the long-term adaptations in various physical and physiological outcomes. Results: Regarding the acute responses after leg-press strength training with or without serial stretch-loading stimuli, visible changes were observed in the muscle force, rate of force development, and hormonal concentrations between pre- and postmenopausal women (only one study). Long-term studies revealed different training adaptations after performing leg-press strength training with unique serial stretch-loading stimuli. A positive trend for leg-press strength training with serial stretch-loading was recorded in the young population and athletes; however, more variable training effects favoring one or the other approach were achieved in the older population. Conclusion: In summary, this review shows the uniqueness and usability of a leg-press device that is capable of various exercising modes, including special serial stretch-loading stimuli. The use of this device can serve as a positive addition to training regiments, and the main application appears to be suitable for rehabilitation needs.
