Abstract ▼ AI-Helper

Sports drinks help optimize and improve performance by delaying and eliminating the buildup of fatigue-causing substances in the body during exercise. Saengmaeg-san is a nature-friendly traditional beverage that has no side effects on the human body and can quench thirst. However, studies on the relationship between exercise ability and Saengmaeg-san are insufficient. The purpose of this study was to prescribe Saengmaeg-san during the summer training period of 4 weeks and to analyze the effect on body composition and exercise performance. Seventeen male participants were divided into 3 groups (Saengmaeg-san acid intake group [n=9], placebo group [n=8]), and body composition (height, weight, muscle mass, fat mass, BMI) and conducted exercise performance (total exercise time and HRmax). In our study, Saengmaeg-san intake had a positive effect on exercise performance, such as decreased body fat percentage, increased exercise time, and decreased HRmax. Therefore, Saengmaeg-san showed the potential as a sports drink. In the future, additional studies on fatigue-related substances, immune function-markers, and blood lipids are needed in order to clearly explain the change in exercise performance due to consumption of Saengmaeg-san.

문제 정의

The purpose of the present study was to evaluate the effect of Saengmaeg-san intake on changes in body composition and exercise performance during the 4 weeks of summer training in college tennis players. The authors hypothesized that participants in the group consuming Saengmaeg-san would experience a positive effect on body composition and exercise performance compared to those in the placebo group.
In this study, considering the advantages of the individual substances, as stated previously, the authors hypothesized that their synergistic effects in Saengmaeg-san would result in superior outcomes. Therefore, the aim of this study was to prescribe Saenmaeg-san to college tennis players during the 4 weeks of summer training and analyze its effects on body composition and exercise performance.

가설 설정

There has been steady progress in studies on ginseng, lilyturf roots, and schisandra berries; however, studies on the relationship between exercise capacity and Saengmaeg-san are insufficient. In this study, considering the advantages of the individual substances, as stated previously, the authors hypothesized that their synergistic effects in Saengmaeg-san would result in superior outcomes. Therefore, the aim of this study was to prescribe Saenmaeg-san to college tennis players during the 4 weeks of summer training and analyze its effects on body composition and exercise performance.
The purpose of the present study was to evaluate the effect of Saengmaeg-san intake on changes in body composition and exercise performance during the 4 weeks of summer training in college tennis players. The authors hypothesized that participants in the group consuming Saengmaeg-san would experience a positive effect on body composition and exercise performance compared to those in the placebo group. Consequently, significant changes were detected among participants in the Saengmaeg-san intake group: a decrease in body fat percentage, an increase in exercise time, and a decrease in maximum heart rate.

제안 방법

All participants had the same breakfast before the start of the experiment, and both groups received the drinks in the same small plastic bag according to the double-blind test design. The test group received Saengmaeg-san and the placebo group received 100% pure water.
The purpose of the study was explained to all participants, who then voluntarily expressed their intention to participate, and subsequently consented in writing. All participants were examined and interviewed by doctors and were tested to confirm the absence of neurological or musculoskeletal diseases. The participants were restricted from consuming nutritional supplements or drugs that could affect the outcomes of the study 1 month prior to commencement.
The program consisted of 10 minutes each of warm-up and clean-up exercises, and 60-70 minutes of the main exercise with an intensity of 70-90% Heart Rate Reserve (HRR) and Rating of Perceived Exertion (RPE) 15-17, 5 times a week for 4 weeks. Basic skill practice, e.g., running strokes, volley and smash, and practice competition (1 set) were conducted as main exercise.
However, two participants were eliminated during the experiment due to injury or absence, resulting in 17 participants(Saengmaeg-san intake group [n=9], placebo group [n=8]). Changes in body composition(height, weight, muscle mass, body fat mass, and BMI) and exercise performance (total exercise time and HRmax) were analyzed immediately before and immediately after the 4-week exercise program. For successful implementation of the study, the researchers monitored the training programs as well as lifestyle-related parameters of the participants, namely eating habits, additional exercise, and medical treatments.

m) before and after. The participants wore simple clothing that was devoid of any metal components and maintained an empty stomach for accurate measurement.
The POLAR (Polar RS400sd, APAC, 90026360, USA) heart rate monitor watch was used to measure the changes in heart rate in real time. The program consisted of 10 minutes each of warm-up and clean-up exercises, and 60-70 minutes of the main exercise with an intensity of 70-90% Heart Rate Reserve (HRR) and Rating of Perceived Exertion (RPE) 15-17, 5 times a week for 4 weeks. Basic skill practice, e.
This double-blind study was conducted on college tennis players to verify the effectiveness of Saengmaeg-san. The study process was divided into pre-test, 4-week experimental session, and post-test stages. Twenty participants were initially included, ten each in the Saengmaeg-san intake and placebo groups.

All participants had the same breakfast before the start of the experiment, and both groups received the drinks in the same small plastic bag according to the double-blind test design. The test group received Saengmaeg-san and the placebo group received 100% pure water. The intake method was based on that described in previous studies on herbal beverages.
Twenty male tennis players who were enrolled in P University were initially selected, out of which 17 players who took Saengmaeg-san and participated in the training program for 4 weeks were selected as final participants. The purpose of the study was explained to all participants, who then voluntarily expressed their intention to participate, and subsequently consented in writing.

데이터처리

The data were analyzed using SPSS ver. 21.0 (IBM Corp., Chicago, IL, USA) to calculate the mean (M) and standard deviation (SD) of the measurement items; repeated measures ANOVA was performed to determine the differences in body composition and exercise performance variables before and after the intake of the Saengmaeg-san extract, followed by Bonferroni’s multiple comparison tests for post-hoc analysis.

이론/모형

Exercise performance was measured using the Schiller CS-200 system (Ergo-Spiro, Schiller AG, Switzerland) with an incremental load exercise method. Based on the Bruce protocol, wherein the speed is increased by 0.

성능/효과

05). Based on these results, it may be considered that Saengmaeg-san has a positive effect on body fat reduction by increasing the efficiency of energy consumption. In addition, the vitamins and various mineral components in Saengmaeg-san affect physiological metabolism in the body, thereby reducing body fat percentage.
The authors hypothesized that participants in the group consuming Saengmaeg-san would experience a positive effect on body composition and exercise performance compared to those in the placebo group. Consequently, significant changes were detected among participants in the Saengmaeg-san intake group: a decrease in body fat percentage, an increase in exercise time, and a decrease in maximum heart rate.
First, the exercise time increased from 13.53±0.80 to 14.98±0.98 among participants in the Saengmaeg-san group, and 12.19±1.19 to 12.46±1.06 among those in the placebo group (P<0.001), showing an interaction effect (P<0.05) and a significant difference in the main effects based on time periods (P<0.01) and groups (P<0.001).

후속연구

In the future, additional studies on fatigue-related substances, hormones related to immune function, and blood lipids are needed to clearly explain the changes in exercise performance in accordance with the intake of Saengmaeg-san. Furthermore, the authors look forward to a study pertaining to the physiological mechanism by which Saengmaeg-san improves exercise performance.
