“…The reason for a high number of circulating PLT in the blood (thrombocytosis) after intense soccer exercise can be explained by epinephrine hormone secration, which has the ability to cause a strong contraction of the spleen (the storage area of one-third of the body’s PLT), and may play a role in the increase in PLT after exercise [ 51 ]. Likewise, it was declared that the mechanisms related to the increase in PLT after high intensity exercises were not clear [ 48 ].…”

Background: Pre-season training in soccer can induce changes in biological markers in the circulation. However, relationships between chosen hematological and biochemical blood parameters and training load have not been measured. Objective: Analyze the blood measures changes and their relationships with training loads changes after pre-season training. Methodology: Twenty-five professional soccer players were assessed by training load measures (derived from rate of perceived exertion- known as RPE) during the pre-season period. Additionally, blood samples were collected for hematological and biochemical analyses. Results: For hematological parameters, significant increases were found for platelets (PLT) (dif: 6.42; p = 0.006; d = −0.36), while significant decreases were found for absolute neutrophils count (ANC) (dif: −3.98; p = 0.006; d = 0.11), and absolute monocytes count (AMC) (dif: −16.98; p = 0.001; d = 0.78) after the pre-season period. For biochemical parameters, there were significant increases in creatinine (dif: 5.15; p = 0.001; d = −0.46), alkaline phosphatase (ALP) (dif: 12.55; p = 0.001; d = −0.84), C-reactive protein (CRP) (dif: 15.15; p = 0.001; d = −0.67), cortisol (dif: 2.85; p = 0.001; d = −0.28), and testosterone (dif: 5.38; p = 0.001; d = −0.52), whereas there were significant decreases in calcium (dif: −1.31; p = 0.007; d =0.49) and calcium corrected (dif: −2.18; p = 0.015; d = 0.82) after the pre-season period. Moreover, the Hooper Index (dif: 13.22; p = 0.01; d = 0.78), and all derived RPE measures increased after pre-season period. Moderate-to-very large positive and negative correlations (r range: 0.50–0.73) were found between the training load and hematological measures percentage of changes. Moderate-to-large positive and negative correlations (r range: 0.50–0.60) were found between training load and biochemical measures percentage of changes. Conclusions: The results indicated heavy physical loads during the pre-season, leading to a decrease in immune functions. Given the significant relationships between blood and training load measures, monitoring hematological and biochemical measures allow coaches to minimize injury risk, overreaching, and overtraining.

Menopause is an important period of life for women, all of whom experience this natural state. However, awareness of the bodily changes during this period is of great significance. Hence, not paying attention to the dietary, physical, and psychological criteria can reduce the quality of women’s lives. This study aimed to evaluate health-related quality of life (HRQoL), body composition, and physical fitness in postmenopausal women after Pilates exercises. Thirty postmenopausal Iranian women were randomly divided into Pilates (performed for 8 weeks) and control groups. The HRQoL Questionnaire (SF-12) was filled out, and a three-day record of food intake was also kept for dietary assessment. The diet of the women consisted of mean values of 1,923 Kcal daily energy, 16% protein, 72% carbohydrate, 12% fat, and 11.32 mg iron. Calcium, zinc, vitamin D, and vitamin E intake were respectively 73, 87.5, 81.7 and 83.53% of the recommended daily allowance. Pilates exercises had a significant effect on flexibility (P=0.002), endurance (P=0.001), muscle strength (P=0.001), body mass index (P=0.001), lean mass (P=0.003), body fat percentage (P=0.001), and quality of life (P=0.001). Therefore, Pilates is an appropriate training to increase body fitness and improve body composition, lean mass, and quality of life in postmenopausal women.
