Abstract
The impact of maternal physical activity on offspring health and phenotypic changes due to exercise has emerged as a significant area of interest in exercise physiology in recent years. Therefore, the aim of this study was to determine the effect of a maternal high-intensity interval training (HIIT) program on the expression of PGC1α and SIRT1 genes in the skeletal muscle of first-generation offspring in Wistar rats. Twenty-four 8-week-old female Wistar rats were acclimatized to the environment and then divided into three groups: a maternal control group, a maternal pre-pregnancy exercise group, and a maternal exercise group that trained both before and during pregnancy. The pre-pregnancy exercise regimen lasted 6 weeks, while the exercise during pregnancy lasted 3 weeks. The exercise protocol involved treadmill running, consisting of 5 days per week, with each session including 1 minute of running at 85-100% of VO2peak and a 10% incline, followed by 2 minutes of rest at 65% of VO2peak and 0% incline. The number of intervals started at 10 and increased based on the overload principle. The control group remained sedentary during this period. After the exercise period and the birth of the offspring, male offspring were categorized according to their maternal groups, and the expression levels of PGC1α and SIRT1 genes in their skeletal muscle were evaluated at 10 weeks of age. Data were analyzed using ANOVA and Tukey's post-hoc test.
The results indicated that after the 6-week HIIT program, both the pre-pregnancy exercise group and the group that exercised before and during pregnancy showed significant differences in speed and distance in the functional performance test compared to the control group (P < 0.05). Additionally, significant differences were observed in the expression of PGC1α and SIRT1 genes among the groups after the birth of the offspring. These differences were significant between the pre-pregnancy exercise group, the pre- and during-pregnancy exercise group, and the control group (P < 0.05). It appears that maternal exercise before and during pregnancy induces changes in the mitochondrial genotype of the offspring, with a more pronounced effect on the expression of mitochondrial genes such as PGC1α and SIRT1 when exercise occurs both before and during pregnancy compared to exercise before pregnancy alone.

Abstract
Vitamin C consumption is important in Iron absorption. Therefore, the purpose of this study was to investigate the effect of acute aerobic activity after two weeks vitamin C supplementation on Iron status and hematological indices in club football players. In this quasi-experimental study, 40 club football players from Khuzestan province were randomly divided into two groups of vitamin C and placebo. Daily and for 14 days, subjects received 400 mg vitamin C in vitamin C group and 400mg dextrose in placebo group. 48 hours after the end of supplementation, a Bruce test was performed. To measure Iron, Ferritin, RBC and Hb levels, four blood samples were taken from the subjects, before and after the supplementation, immediately after and 72 hours after the Bruce test. Repeated measure ANOVA and Two way analysis of variance was used. 2 weeks of vitamin C supplementation showed a significant increase in RBC (p=0.026), Hb (p=0.041), serum Iron (p=0.008) and serum Ferritin (p=0.004) compared to placebo group. After aerobic exhaustive activity, RBC (p=0.034), serum Iron (p=0.023) and Ferritin (p=0.031) in vitamin C group significantly decreases compared to placebo group. After 72 hours of recovery, the vitamin C group showed a significant increase in serum Iron (p=0.036) and Ferritin (p=0.045) compared to placebo group. It seems that two weeks of vitamin C supplementation can improve the serum Iron, Ferritin, RBC and Hb profile of professional footballers before aerobic exhaustive activity and in recovery.

Abstract
Background and Aims:The necessity and importance of such research, especially among the young is quite tangible. The purpose of the present study was to compare the effect of 8 weeks of corrective selected exercise and combination kinesiotaping and tera band training on the kyphosis angle of adolescent boys with kyphosis. Materials and Methods: In this quasi-experimental study, spinal deformity information of 36 boy students in gym of Esfahan city, 15-18year participated in this study. Then boy student’s participated in an 8-week corrective selected exercise and Combination of Kinesiotaping and Teraband، the end their deformity were evaluated again.For data analysis descriptive statistics ، T tests and SPSS Software was used.The angleof kyphosis in pre-test (48/8± 0/9) after using corrective selected exercise have had a significant reduction (46/9±0/8). Angle of kyphosis in pre-test (49. 1 ± 0.7) after using Combination of Kinesiotaping and Teraband have had a significant reduction (46/97±0/8). Conclusion:corrective exercises alone or in combination with new methods of training, the subjects had a positive impact on improving the kyphosis. But according to the results of this study, no significant difference was found between the corrective exercises with the combined method.
