Despite its profound impact on athletic performance, the significance of heart rate recovery (HRR) has been insufficiently addressed in the filed of sports science, particularly in the context of weightlifting characterized by brief and intense exertions involving heavy weights. Serving as a valuable indicator of autonomic nervous system and cardiovascular function, HRR assumes a pivotal role in weightlifting. This comprehensive review aims to delineate the specific demands for HRR in weightlifting, shedding light on the often overlooked cardiovascular considerations within training regimes focused on strength and power. The investigation scrutinizes the repercussions of HRR on weightlifting performance, seeking to elucidate how inadequate recovery intervals may result in physiological and psychological consequences. These consequences encompass a distorted perception of effort, disruption of coordination, compromised posture due to irregular breathing, and an overall decline in lifting capacity. The review systematically presents compelling evidence pertaining to heart rate response and recovery patterns during weightlifting, underscoring the critical importance of well-structured rest periods. Furthermore, the review delves into a comprehensive discussion of factors influencing HRR in weightlifting, encompassing variables such as sex, age, cardiovascular function, hydration, nutrition, and psychological aspects. Finally, a key emphasis is placed on the integration of effective HRR techniques into the training regimens of weightlifters, thereby ensuring sustained and optimized performance outcomes.

Objective: The objective of this study was to investigate the effects of Schroth's three-dimensional exercises in combination with respiratory muscle exercise (SERME) on Cobb's angle and functional movement screen (FMS). Design: Randomized controlled trial. Methods: Fifteen subjects with scoliosis were randomly assigned to two groups. Eight subjects were assigned to the experimental group and seven subjects were assigned to the control group. The experimental group underwent SERME using SpiroTiger (Idiag, Switzerland), while the control group performed only the Schroth's three-dimensional exercises (SE). Both groups performed exercises for one hour per day, three times a week for eight weeks. Cobb's angle, pulmonary function (forced vital capacity, forced expiratory volume at one second, and peak expiratory flow) and FMS were measured before and after the experiment. Results: After intervention, the SERME group showed a significant difference in Cobb's angle, FMS scores, and pulmonary function as compared to before intervention (p<0.05). In the SE group, there was a statistically significant difference in Cobb's angle, pulmonary function, and FMS scores compared to before intervention (p<0.05). The SERME group showed a significant difference in Cobb's angle and peak expiratory flow in pulmonary function compared to the SE group (p<0.05). Conclusions: The results suggest that SERME could be a more effective intervention for improvement of the Cobb's angle and pulmonary function for scoliosis patients.

Purpose: The purpose of this study is to investigate the effect of work intensity on fit factor and affective quality of the dustproof Background: Among the victims who suffer pneumoconiosis due to the inhalation of toxic substances or the lack of oxygen during the work, the proportion of the victims is larger than the other causes. Wearing a respirator may prevent pneumoconiosis, but it can be hazardous to workers because of the leakage through filters, cartridges, exhaust valves, broken parts, and face-to-face contact. Despite leakage through the contact area between the mask and the face has various causes such as the wearer's activity, sweat accumulation, facial shape, etc., There is a lack of relevant research and regulation compared to developed countries that have already institutionalized the law 30 years ago and give the right to sell through a test Method: The work intensity was adjusted by walking or running at 6km/h and 11km/h on the treadmill, and tasks were defined with reference to the test procedure and the exercise sequence applied in the face leakage test of the dustproof mask. And fit factor was measured objectively using 'Respirator Fit Tester 8038' which measures fit factor calculated by dividing the number of dust present outside the mask by inside the mask. In addition, affective quality was classified by the ease of use, ease of breathing, and ease of wearing, and was measured using the 5-point likert scale questionnaire. Results: There was a significant difference in fit factor, ease of breathing, and wearing convenience according to work intensity and no significant difference in ease of use(${\alpha}=0.01$). And when the work intensity was high, fit factor, ease of breathing, and wearing convenience were all lower than when the work intensity was low. Conclusion: In Korea, it is necessary to consider consideration of the work intensity when testing the leakage rate of the face part for safety certification of the respiratory protective equipment, When developing a mask, it should be possible to maintain high adhesion even under intense, active situation and high temperature conditions by selecting materials, improving the wearing style, and expanding the adjustable range.

In old age, measures to cope with the natural phenomenon of aging and various diseases of the elderly due to the deterioration of physical function are also a challenge for this society. While interest in systematic health is increasing, it is true that awareness and interest in oral-related diseases is relatively lacking. This study aims to present basic data necessary to improve the quality of life for senior citizens aged 65 or older by improving the oral dryness caused by systemic health. By research method, improve oral dryness caused by whole-body health with the elderly over 65 and promote their oral health, inducing the increase of the salivary flow rate through oral health care education, oral exercise, and salivary gland massage. First, on the DMSQ according to the general characteristics of the elderly, the recognition of the whole body and oral health status, independent sample t-test and One-way ANOVA were conducted. Second, on changes in the salivary flow rate and saliva pH according to the general characteristics of the elderly, recognition of oral and whole-body health status, and whole-body health, paired samples t-test was conducted. Studies have shown that salivary gland flow increased significantly after oral exercise and salivary gland massage, the salivary flow rate significantly increased. In all variables of the recognition of the oral health status, the salivary flow rate increased after oral exercise and salivary gland massage, and in the whole-body health, regardless of hypertension, diabetes, cardiovascular disorders, and osteoporosis, the salivary flow rate increased after oral exercise and salivary gland massage, and the salivary flow rate increased after oral exercise and salivary gland massage if the subjects responded that they did not have thyroid abnormality, anemia, abnormalities of breathing, hypotension, gastrointestinal disturbance, or kidney diseases. As a comprehensive analysis of this study, many felt oral dryness when they had a problem with the whole-body health, and many felt oral dryness when they had a problem with oral health cognition. After applying oral exercise and salivary gland massage as intervention methods in the oral health care for the elderly, the salivary flow rate significantly increased, and it is judged that the methods were very effective for controlling oral dryness. Furthermore, it is judged that the factors affecting oral health, whole-body health, and oral dryness would be identified, which would be helpful for the promotion of whole-body health and oral health. It is judged that continuous research would be needed so that measures for the application of the oral care program and system for the elderly would be prepared in the future.
