“…Contrary to the results of the present study regarding weight gain in the RT + CEE group, Jose [21] concluded that total creatine supplementation with RT did not cause significant changes in body weight and fat free mass after four weeks of RT and creatine consumption. Similarly, Jagim et al [20] found that creatine monohydrate consumption did not significantly reduce body fat percentage in subjects, and despite the increase in weight, the observed changes were not significant.…”

“…Also, in the case of muscle mass, the results showed that leg and arm muscle masses were significantly increased in the RT + CEE group, but no significant changes were observed in the RT + PL group. In similar studies, Jose [21] showed that after four weeks of RT, when creatine supplementation was consumed immediately after exercise, it increased their strength. Gualano et al [16], studying the effect of creatine supplementation and RT, concluded that creatine monohydrate consumption and RT for 24 weeks improved muscle mass and muscle function.…”

“…Contrary to these two hormones, cortisol is a catabolic hormone and is associated with an increase in the amount of protein catabolism, which can have an effect on the prevention of skeletal muscle hypertrophy [8]. Serum cortisol levels are affected by various factors such as intensity, duration, exercise time, type of exercise, age, height, ambient temperature and psychological state [5].…”

SummaryStudy aim: The aim of this study to determine whether creatine ethyl ester (CEE) supplementation combined with resistance training (RT) is effective for improving hormonal changes, body composition and muscle strength in underweight non-athlete men.Materials and methods: Sixteen underweight non-athlete men participated in this double-blind study and were randomly assigned to one of two groups: RT with placebo (RT + PL, n = 8) and RT with CEE supplementation (RT + CEE, n = 8). The participants performed 6 weeks of RT (60–80% 1RM) combined with CEE or PL. 48 hours before and after the training period, muscle strength (1RM for leg press and bench press), body composition (percentage of body fat, circumference measurements of the arm and thigh), serum levels of testosterone, cortisol, and growth hormone (GH) of the participant were measurements.Results: Significant increases were observed for weight, muscle strength and muscle mass, serum levels of testosterone and GH between pre and post-test in the RT + CEE group (p < 0.05). In addition, cortisol level was significantly decreased in the post-test in the RT+CEE group. The decrease in fat percent was greater in the RT + PL group than in the RT + CEE group (%change = –6.78 vs. –0.76, respectively). Weight and leg strength changes in the RT + CEE group were significant compared to the RT + PL group (p < 0.001, p = 0.05, p = 0.001; respectively). However, in other variables, despite the increase of GH and testosterone levels and lower levels of cortisol in the RT + CEE group, no significant differences were observed between the two groups (p < 0.05).Conclusion: It seems that the consumption of CEE combined with RT can have significant effects on body weight and leg strength in underweight non-athlete men. This supplement may provide a potential nutritional intervention to promote body weight in underweight men.

“…In our study, the aerobic exercise program significantly reduced TSH level among obese women. This is consistent with the findings of Beyleroglu et al (9) and Bansal et al (28) but inconsistent with the findings of Nicoll et al (29). Production and secretion of the thyroid hormones is regulated by TSH, which is secreted from the pituitary gland.…”

Background and objectives: Studies have shown that exercise can affect hormone secretion and some metabolic and endocrine functions. The aim of this study was to assess the effect of eight weeks of aerobic training on thyroid hormones and quality of life in obese postmenopausal women. Methods: In this semi-experimental study, 21 obese (body mass index >30 Kg/m 2) women aged between 35 and 45 were randomly divided into an experimental (n=10) group and a control group (n=11). The subjects in the experimental group performed 30-60 minutes of aerobic exercise at 65-75% of maximum heart rate, three times a week, for eight weeks. Level of thyroid hormones and quality of life subscales were compared within and between the groups. Statistical analysis was performed at significance level of 0.05. Results: After the eight-week exercise program, thyroxine, triiodothyronine and thyrotropin releasing hormone levels increased significantly, and thyroid releasing hormone level decreased significantly (P=0.001). The exercise program also had significantly positive effects on quality of life and its occupational, sexual and emotional subscales in obese postmenopausal women. Conclusion: Aerobic exercise causes a significant increase in levels of thyroxine, triiodothyronine and thyrotropin releasing hormone and some subscales of quality of life. It also causes a significant decrease in thyroid releasing hormone level, which indicates the effect of exercise on hormone secretion.

“…Additionally, many data have provided discordant results concerning associations of circulating TSH and physical activity. In young men both no changes and significant elevation in circulating TSH were noted immediately after maximal aerobic exercise [9][10][11]. In addition it was shown that long term exercise may have different impacts on TSH levels than an acute exercise program [12].…”

Background Our study was aimed at the evaluation of relationships between thyroid stimulating hormone (TSH) within the normal range and metabolic risk factors (glucose, insulin, HOMA-IR and lipoprotein profile) in physically active male and female students. Methods In 112 male and 107 female students circulating TSH, glucose, insulin and lipoproteins (triacylglycerols, total cholesterol, HDL-cholesterol and LDL-cholesterol) were measured in blood under fasting conditions. Insulin resistance was expressed as HOMA-IR. For further procedures 99 males and 97 regularly menstruating females with TSH 0.4 – 4.0 µIU/ml were accepted. Results In male students no correlations between circulating TSH, anthropometric and biochemical variables were noted. In females TSH within the normal range was slightly but significantly correlated with the triglyceride (TG) level (p<0.03). However, step-wise multiple regression analysis revealed that the effect of TSH was small (p<0.046) in relation to that found for HOMA-IR (p<0.0009). No relationships between biochemical variables and normal levels of TSH were noted in male students. However, surprisingly normal range TSH in males was slightly but significantly correlated with the percentage of body fat and this issue needs further studies concerning measurements of different fat depots.Conclusions The above data suggests that in active females TG synthesis and export from the liver is more sensitive to TSH action than in active male counterparts.
