The effects of different doses of garlic supplementation on coagulation times after an acute endurance exercise are likely to be varied. The aim of this study was to investigate the effects of different doses of garlic supplementation on partial thromboplastin time (aPTT) and prothrombin time (PT) after an acute endurance exercise in young athletic men.

Fifteen healthy young active men in the competition stage (age 27.0±7.9 years; weight 73.9±6.4 kg; and VO2max 49.59±0.35 ml/kg/min) with at least three years of experience of regular exercise in 5000 m endurance running voluntarily participated in this study. The subjects took different doses of garlic (500,750 and 1000 mg) and starch (placebo) in four separate sessions. In each session, four hours after taking the supplement or placebo, the subjects performed 30 min of running on treadmill at the intensity of 65-85% of target heart rate. Three blood samples were taken before supplementation, before exercise and immediately after exercise. The repeated measures ANOVA and Bonferroni tests were used to analyze the difference between different doses of garlic after acute endurance exercise and the difference between each doses of garlic and placebo at p<0.05.

Three dosage of 500, 750 and 1000 mg garlic were significantly increased aPTT. However, after acute endurance exercise, the three dosages of garlic significantly decreased aPTT. Additionally, the aPTT was significantly more decreased with 500 mg compared to 1000 mg of garlic after acute endurance exercise. There were no significant difference in PT after acute endurance exercise between three different dosage of garlic.

It seems that after an acute endurance exercise in active men, 500 mg of garlic is more effective dose for reducing aPTT.

Long-term endurance training improves aerobic capacity and lactic acid indicators during rest and sports activity. Increasing aerobic capacity and reducing lactic acid by consuming garlic can enhance these beneficial effects and therefore can increase endurance performance. Therefore, this study was conducted with the aim of investigating the effect of 8 weeks of endurance training with garlic supplementation on aerobic capacity and lactic acid in non-professional middle-aged female athletes in zanjan city. Healthy non-athlete women were randomly divided into four groups [garlic supplement (with an average age of 52.33), exercise (53.60), garlic and exercise supplement (53.93) and a control (with an average age of 63.53)]. After Bruce's test (pre-test), a garlic supplement group, a training group (only training) and a garlic supplement and training group (garlic plus training) were given, and the control group did not perform any specific activity. The subjects, at the end of the eighth week, were again Bruce's test was performed to analyze the data, independent t-test and covariance analysis were used, and the significance level was 0.05 in all tests. The results showed that there was a significant difference between the consumption of garlic supplement, exercise, garlic with exercise in increasing aerobic capacity and reducing lactic acid. Also, after 8 weeks, garlic supplementation caused a significant difference in maximum oxygen consumption compared to the control group. The findings of the present study show that consuming garlic during exercise has a significant effect on increasing aerobic capacity and reducing lactic acid in non-athletic women.

The purpose of this study was to compare eight weeks of aerobic exercise and garlic supplementation on the levels of growth factors GH and IGF-1 as well as the sex hormone estrogen in the serum of overweight young women. 40 volunteers were selected as a statistical sample in a purposeful and accessible manner and then randomly divided into four groups: aerobic exercise group (10), walking supplement group (10), exercise and supplement group (10) and control group (10). 10) were divided. The criteria for entering the research include: women who have not taken any medicine or supplement during the last six months, are ready to do sports based on the PAR-Q questionnaire, BMI between 25 and 29.9, age range between 20 and 40 years, not having diseases such as Diabetes, joint problems such as arthritis and not having chronic breathing problems. The training program of the aerobic group included 24 training sessions. The duration of the training session was 40 minutes at the beginning and reached 55 minutes during 8 weeks. The training intensity was 50-70% of the maximum heart rate, which reached 65-80% of the maximum heart rate in the eighth week. Also, every day and for eight weeks, 500 mg of garlic supplement (in capsule form) was given to the garlic supplement consuming groups, and 500 mg glucose capsules similar to the garlic supplement capsules were given to the placebo group. For the purpose of statistical analysis, the Shapiro-Wilk test was used to check the normal distribution of the data and homogeneity of variance using the Levine test. In order to test the hypotheses, the correlated t-test was usedto examine intra-group differences and the analysis of covariance test was used to examineinter-group differences. Also, a significant level was considered for all calculations (α≤0.05). The results of covariance analysis showed that there was a significant difference in the post-test values of growth hormone, insulin-like growth factor-1 and estrogen between the three groups (P<0.01). Correlated t results showed a significant difference in the amounts of growth hormone, insulin-like growth factor-1 and estrogen in the three experimental groups except the control group (P<0.05). The results of the present study showed that eight weeks of aerobic exercise and garlic supplementation lead to an increase in the growth factors GH and IGF-1 as well as thesex hormone estrogen in overweight young women. Therefore, aerobic exercise and garlic supplementation can be recommended to overweight women.

Resistance exercise can reduce inflammation. On the other hand, garlic supplementation may have beneficial effects in combination with resistance training due to its wide-ranging effects, including its effect on inflammation. Therefore, this study aimed to investigate the effect of eight weeks’ progressive resistance training with garlic supplementation on serum hs-Crp levels and insulin resistance in overweight young women.

Forty-eight healthy age range: 20 to 40 years, randomly divided into four groups: resistance training + supplement (age=31.3 ± 3.1y, BMI=28.2 ± 2.7kg/m2), resistance training + placebo (age=30.7 ± 3.8y, BMI=26.4 ± 2.4 kg/m2), Garlic supplement (age=27.9 ± 2.5y, BMI=26.7 ± 3.9 kg/m2) and control (age=29.7 ± 3.8y, BMI=28.8 ± 3.3 kg/m2). Before and after eight weeks of training period, anthropometric data, one repetition maximum (1-RM), C-reactive protein (CRP), insulin and glucose were measured and insulin resistance (IR) was calculated. The subjects of the training group performed a progressive resistance training program for eight weeks, three sessions per week, including three sets with 10 repetitions maximum and one minute rest between sets and movements. Subjects in the supplement and placebo groups took two 500mg tablets of garlic or placebo daily in the morning and at night with a meal. Changes in the results before and after the in four research groups were examined using one-way analysis of variance. If statistical analysis were significant, the Bonferoni posthoc test was used for finding the place of differences.

Significant decrease in serum CRP levels, insulin resistance and glucose was observed in the training + supplement group compared to other groups (P < 0.05). In contrast, insulin levels did not show significant changes in all groups (P > 0.05). Regarding body composition analysis, the results were accompanied by a significant decrease in fat mass and a significant increase in lean body mass, especially in the training + garlic group (P < 0.05).

Although hs-CRP data and insulin resistance index of the present subjects were in the normal range and seemed safe, but in general, according to the results of the present study, it seems that the progressive resistance training program with garlic supplementation had double effects on CRP as important inflammatory index and insulin resistance in overweight women compared to either alone.

The purpose of this study was to compare the effect of six-months of combined care program with garlic supplementation on coagulation factors (INR, PPT, PT) in middle-aged men with DVT. The present study was a quasi-experimental with a clinical trial design (code: IRCT20210718051924N1). Subjects were 40 men (age: 51.50 ±4.01 years, fat percentage: 28.63 ±3.24) with a history of at-least 3 years of DVT who were taking warfarin randomly divided into four groups: Combined-exercise, Combined-exercise +garlic, Garlic and Control. Combined-exercise for 24 weeks, 3 sessions per-week, first resistance training (50 to 60% 1RM) and then aerobic training (55 to 60% of the reserve-heart-rate). 1200mg daily garlic supplement was used in the form of capsules at ten o'clock in the morning. PT, PTT and INR factors were measured before and after 24 weeks. Two-way analysis of variance, paired t-test and Tukey post-hoc test were used (P<0.05). The results showed that both combined-exercise +garlic and consumption of garlic increased the PT (garlic 3.3%, p=0.004; exercise +supplement 13.3%, P=0.001) and INR (garlic 2%, p=0.013; exercise +supplement 46%, p=0.001) had a significant effect, also combined-exercise +garlic on the PTT 1.5% (p=0.014) had a significantly effect. But this wasn’t of effects in the combined-exercises (PT: p=0.355, INR: p=0.259, PTT: p=0.448) and the group Garlic was-not significant in PTT (p=0.504). It is recommended to use combined exercises with garlic consumption because of its effect on PT and INR and the important role of these factors in rebalancing homeostasis.

Purpose of this study was to investigate the short-term effects of garlic supplementation on the isocapnic buffering and hypocapnic hyperventilation phases in healthy young athletes. Thirty healthy young athletes (Age 20. 05 ± 0. 87 yr.، Height 178. 67 ± 4. 76 cm، Weight 71. 55 ± 8. 9 kg) divided into two equal groups: supplementation and placebo. The supplement group received each day for a week 1000 mg of garlic pill and placebo group each day for a week 1000 mg of starch. All of the subjects participated before and after supplementation on self-dependent protocol. V-Slope was measured with the respiratory gas analysis system for estimating the isocapnic buffering and hypocapnic hyperventilation phases. Under curve surface area was estimated using of integration function. Analysis of covariance (ANCOVA) aimed to control the pre-test scores as a covariate was used to analysis the data. Results indicated that short-term garlic supplementation despite of positive effects on the aerobic and anaerobic thresholds as well as the peak values، has no a significant effect on isocapnic buffering and hypocapnic hyperventilation phases. Based on the results we can conclude that presumably short-term supplementation of garlic shifts the isocapnic buffering and hypocapnic hyperventilation area to the right side and delay fatigue which has to be studied in the future.

The purpose of this research was to investigate the effect of endurance training and garlic consumption on VO2max. For this purpose، 33 non- active men with، average age (25. 7±2. 5 yr) randomly divided into four groups: placebo، supplementation، training-placebo and training-supplementation. The Placebo and supplement groups recieved each day for a month 500 mg of starch and garlic powder each each day formonth. Groups daily intake of starch and garlic in addition to three sessions of exercise per week for a three and four had month to run on a treadmill endurance training began. Bruce protocol and gas analyzer was use to determine VO2max. Results showed that VO2max in groups: supplements (1. 75±1.)، training-placebo (2. 62±0. 74) and training-supplements (3. 55±1. 23) were significantly increased compared to placebo (p≤0. 05). Also during the exercise test in two groups training-placebo (41. 62±12. 77 s) and training-supplements (55. 55±28. 68 s) were significantly increased compared to placebo (p≤0. 05). Therefore، endurance training and garlic supplementation was effective on VO2max. But، garlic supplementation had additional effect on increased VO2max in non-active subjects who participated in endurance training.
