“…The deer is the most representative special economic animal with a high reputation both at home and abroad, and its body is full of treasures. Modern research has proved that deer antler has the functions of regulating body metabolism, enhancing physical strength, improving hematopoietic function, promoting growth and development, improving body immunity, and promoting various physiological functions, in addition to deer antler, other deer products, such as antlers, deer whips, deer tails, deer tires, and deer blood, are important nutritional and health care products, therefore, the use of deer antler and by-products to develop functional food is the need for the development of the deer industry, it is the fundamental way to broaden the utilization of deer products, extend the industrial chain, increase the added value of products, and then improve the economic benefits of the deer industry [ 3 ].…”

In order to improve the physical function of athletes under hypoxic training, the authors propose to observe the effect of functional food with active ingredients of polypeptide polyamines in deer antler on the physical function of athletes under ultrasound observation. According to the characteristics of physiological changes during hypoxic training, functional foods containing the active ingredients of polypeptide polyamines in deer antler were selected and given to athletes under simulated hypoxic training, observe the changes of red blood cells (RBC), hemoglobin (Hb), hematocrit (Hct), blood lactic acid, free radical metabolism and immune function of athletes, and musculoskeletal under ultrasound observation, discuss how to improve the physical function and athletic ability of athletes under hypoxic training. Experimental results show that athletes after 6 weeks of hypoxic training, red blood cells and hemoglobin were significantly increased, there was a significant difference compared to the control group ( P < 0.05 or P < 0.01 ). After 6 weeks of hypoxic training, hemoglobin increased by 10.1%, a 5.6 percentage point increase compared to the control group. Conclusion. The antler peptides used by the authors can enhance the effect of hypoxic training.

“…The overall study characteristics are summarized in Table 2 . The included RCTs consisted of five studies using the single-blinding method[ 22 , 23 , 24 , 25 , 26 ], one study with double-blinding[ 27 ], and three studies in which the blinding methods were not described[ 28 , 29 , 30 ]. The total subjects from all nine studies were 274 people with either overweight obesity, elderly, or having sedentary activity[ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ].…”

“…After including overweight-obese population only by eliminating one study with a BMI <25 kg/m 2 (normal weight)[ 26 ], different results were found [ Figure 4 ]. Using the same model as previous by comparing the results of the pre- and post-test in the physical exercise group under hypoxic exposure, the results showed that physical exercise under hypoxic exposure had a low significant effect on reducing blood glucose levels compared to normoxic condition, as indicated by the pooled SMD value of 0.29 (CI = 0.01–0.57; P = 0.04) with the statistical power shows a value of 0.3124.…”

Objectives: To analyze the impact of exercise under hypoxic exposure versus normoxic exposure on blood glucose level, insulin level, and insulin sensitivity in people at risk of Type 2 diabetes mellitus (T2DM). Materials and Methods: We systematically performed electronic searching on PubMed, Web of Science, ProQuest, and Scopus. Primary studies that met the inclusion criteria were analyzed using Revman 5.4.1. Results: Nine randomized controlled trials were included in this meta-analysis. We found that physical exercise under hypoxic exposure had no significant effect on improving blood glucose levels, insulin levels, and insulin sensitivity in the elderly and sedentary people compared to normoxic condition. However, physical exercise during hypoxic exposure had a significant effect on lowering blood glucose levels in overweight/obese individuals (pooled Standardized Mean Difference = 0.29; 95% confidence interval = 0.01–0.57; P = 0.04). Conclusions: Exercising under hypoxic exposure can be an alternative strategy for reducing blood glucose levels in overweight/obese people. Nevertheless, in other populations at risk of T2DM, exercising in hypoxic conditions gives similar results to normoxic conditions.

Introduction: The most evident change during exercise is the increase in oxygen demand, and prolonged high-intensity exercises may impact this even more on this demand. Physical training with progressive loads is a method that aims to reach the training goals by adjusting factors such as initial load, stage load, and a load of the athletes and can be a monitor of the aerobic and anaerobic exercise on the athlete with potential benefits for the high demand of oxygenation. Objective: Study the changes in heart rate and indexes of cardiorespiratory endurance of sprinters under training with progressive loads. Methods: By random sampling, the study subjects were 15 male sprinters and 15 non-sportsmen as research volunteers. The study subjects performed a protocol with progressive load training on a platform. All subjects underwent the Italian Kosmai cardiopulmonary function test before and after training. Results: The subjects who did not practice the sport showed VO2 max values at an exercise intensity of 13 km/h. The VO2 max maximum for sprinters was 15 km/h. Individuals who were not sprinters generally showed lower VT levels than sprinters (P <0.05). Average non-speeder individuals demonstrated higher MET scores than sprinters. Conclusion: Cardiopulmonary endurance and energy metabolism levels are strongly related to long-term participation in physical activity and exercise intensity. Incremental load training improved cardiorespiratory fitness in sprinters. The results may provide a specific theoretical basis for the daily training of sprinters in the future. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
