The Added Effect of Respiratory Training on Stabilometric, Respiratory and Agility Outcomes Among Recreational Athletes: an Experimental Design

Background Diaphragm activation plays a crucial role in various function activities through the adequate core muscle setup. In order to bring a change in balance, agility, and respiratory outcomes in recreational athletes, the role of combined diaphragm and balance training is still under debate. Purpose The study aimed to investigate the added effect of respiratory training on balance training in recreational athletes. Methods Forty-two male recreational athletes were randomized into either the balance training group alone or the added respiratory training group. Result The result of the study revealed that the agility, balance, and respiratory outcomes were improved significantly (p < 0.05) in the combined respiratory and balance training group. However, in the balance training group seperately, the respiratory and agility outcomes did not improve significantly (p > 0.05), but the balance outcomes improved significantly (p < 0.05). Conclusion The study concludes that additional respiratory training can help enhance respiratory and agility outcomes compared to balance training alone.

Plyometric and Resistance Training: A Dual Approach to Enhance Physical Fitness in 12–15-Year-Old Girls

Background/Objectives: This study aimed to evaluate the effects of an 8-week combined plyometric and resistance training program on the physical fitness (PF) of adolescent girls aged 12 to 15 years. The objective was to determine whether combined training (CT) would yield greater improvements in performance measures compared to resistance training (RT) alone. Methods: Forty-seven adolescent girls were randomly assigned to either the CT group or the RT group. Performance measures such as the 20 m sprint, squat jump, vertical jump, handgrip strength, and flexibility (sit and reach test) were assessed before and after the 8-week intervention. Changes in these measures were analyzed to compare the effects of the two training approaches. Results: The CT group showed a significant reduction in sprint time (−6.5%) compared to the RT group (−4.1%), although the difference was not statistically significant. Squat jump height improved significantly by 5.6% in the CT group compared to 1.1% in the RT group (p < 0.05). Similarly, vertical jump height increased by 6.7% in the CT group and by 2.4% in the RT group (p < 0.05). Handgrip strength improved by 7.5% in the CT group and 4.6% in the RT group, with no significant differences between the groups. Flexibility showed slight, non-significant improvements in both groups. Conclusions: The findings suggest that a combined plyometric and RT program is more effective in enhancing explosive power, specifically squat and vertical jump performance, in adolescent girls compared to RT alone. These results highlight the potential of CT programs for improving overall physical performance in this population.

An Effective Method of Aerobic Capacity Development: Combined Training with Maximal Aerobic Speed and Small-Sided Games for Amateur Football Players

This study aimed to investigate the effects of combined training with maximal aerobic speed and small-sided games on football players’ aerobic capacity development. Methods: The football players were divided into three groups as a combined training group (n = 20) (Mean ± SD age 23.40 ± 2.92 yrs, BMI was 23.67 ± 1.59 kg/m2, mass: 74.80 ± 5.46 kg, height: 177.73 ± 4.31 cm), maximal aerobic speed group (n = 20) (Mean ± SD age 23.93 ± 2.46 yrs, BMI was 23.32 ± 1.42 kg/m2, mass: 72.66 ± 5.38 kg, height: 176.46 ± 4.99 cm) and regular training group (n = 20) (Mean ± SD age 24.80 ± 5.84 yrs, BMI was 22.87 ± 1.67 kg/m2, mass: 73.06 ± 6.74 kg, height: 178.33 ± 7.98 cm). In addition to regular football training, maximal aerobic speed training with small-sided games was applied to the combined training group (CT) and only maximal aerobic speed training was applied to the maximal aerobic speed group (MAS) twice a week for 12 weeks. The normal training group (NT) continued their routine football training programme. All participants applied the Yo-Yo IR1 test in the pre-test and post-test of the study. As a result of normality tests, it was determined that the data showed normal distribution, and the ANOVA test and Tukey’s multiple comparison test were used in the intergroup evaluation. Results: When the Yo-Yo IR1 Test pre-test and post-test results were analysed, maximal aerobic speed training with small-sided games (CT) and maximal aerobic speed (MAS) groups were significantly higher compared to the normal training (NT) group regarding training load, running distance, and VO2max value among the football players (p = 0.001). There was no difference in the normal training group (p > 0.05). As a result, it was determined that combined training with maximal aerobic speed, small-sided games, and only maximal aerobic speed effectively improved football players’ aerobic capacity and general performance.

Impact of spinach thylakoid extract-induced 12-week high-intensity functional training on specific adipokines in obese males.

Obesity presents multifarious etiopathologies with its management being a global challenge. This article presents the first ever report on the impact of spinach thylakoid extract-induced high-intensity functional training (HIFT) on obesity management via regulating the levels of novel adipokine, C1q/TNF-related Protein-12 (CTRP-12), furin, and Krüppel-like factor 15 (KLF-15). Sixty-eight obese male subjects were randomly divided into four groups: control group (CG), supplement group (SG), training group (TG), and the combined training and supplement group (TSG). After initial assessments of all groups, the training group commenced a twelve-week HIFT using the CrossFit program (comprising of three training sessions per week, each lasting 30 min). Eligible candidates were randomly assigned to either receive thylakoid-rich spinach extract (5 g per day) or a matching placebo (5 g per day of corn starch, 30 min before lunch) for a total duration of 12 weeks. All required data and investigations were collected at 48 h pre- and post-training. The results indicated a substantial correlation between exercise and the time of KLF-15, furin, and CTRP-12 demonstrating effect sizes of 0.3, 0.7, and 0.6, respectively. Additionally, the training and supplementation group (TSG) exhibited a substantial decrease in low-density lipoprotein (LDL), total cholesterol (TC), and triglyceride (TG) levels (p < 0.0001). Concurrently, there was a significant increase in high-density lipoprotein-cholesterol (HDL-C) levels (p = 0.0001). Furthermore, a notable difference between the groups emerged in HDL, LDL, TC, and TG levels, supported by effect sizes of 0.73, 0.86, 0.96, and 0.89, respectively (p < 0.05). The study offered novel insights into the management of obesity using supplements induced by spinach-derived thylakoid extract during a 12-week HIFT program. The proposed combination intervention may reverse obesity-induced insulin resistance and metabolic dysfunctions by positive regulation of CTRP-12/adipolin and KLF15 and simultaneous suppression of furin levels.

The Combined Effects of Endurance and Strength Training on Exercise Tolerance and Quality of Life in Patients with COPD

Chronic Obstructive Pulmonary Disease (COPD) significantly impairs exercise tolerance and quality of life due to respiratory and systemic effects. Exercise training, including endurance and strength modalities, is a cornerstone of pulmonary rehabilitation, yet the combined effects of these training methods remain underexplored. This study aimed to evaluate the combined effects of endurance and strength training on exercise tolerance and quality of life in COPD patients. A randomized controlled trial was conducted involving 100 COPD patients assigned to four groups: Endurance Training, Strength Training, Combined Training, and Control. The interventions were implemented over 12 weeks, with outcomes assessed pre- and post-intervention, including the six-minute walk test (6MWT) for exercise tolerance and the St. George’s Respiratory Questionnaire (SGRQ) for quality of life. Statistical analyses included ANOVA and post-hoc comparisons to determine group differences. The Combined Training group demonstrated the most significant improvement in exercise tolerance, with a mean increase of 72.4 meters in 6MWT distance, compared to 48.7 meters in the Endurance group and 34.2 meters in the Strength group. Quality of life, measured by SGRQ, improved significantly across all intervention groups, with the greatest reduction in total SGRQ scores observed in the Combined Training group (12.6 points), indicating enhanced physical and psychological well-being. Additional improvements in muscle strength and endurance capacity were also most pronounced in the Combined Training group. Combined endurance and strength training provide superior benefits in enhancing exercise tolerance, muscle strength, and quality of life in COPD patients compared to either modality alone. These findings support the integration of multimodal exercise regimens in pulmonary rehabilitation programs to optimize outcomes for COPD patients.

High-intensity intermittent inspiratory and abdominal muscle combined training in respiratory, swallowing and systemic muscles of healthy adults.

Low-intensity continuous inspiratory muscle training improves its strength. The abdominal muscles are the main expiratory muscles, and their training may improve expiratory muscle strength. Respiratory muscle strength regulates coughing effectiveness, which is critical for pneumonia management. In older people, risk factors for the development of pneumonia were respiratory muscle weakness and swallowing impairment. Currently, the impact of high-intensity intermittent inspiratory and abdominal muscle combined training on the respiratory, swallowing, and systemic muscles is unclear. We aimed to explore the effects of high-intensity inspiratory muscle training combined with or without abdominal muscle training on respiratory muscle strength as well as the strength, mass, and performance of swallowing and systemic muscles. Twenty-eight healthy adults were divided into two groups. Participants performed high-intensity intermittent inspiratory muscle single or its combination with abdominal muscle training for 4 weeks. Respiratory muscle strength, swallowing muscle strength and mass, systemic muscle strength, mass and performance were measured at baseline, Week 2 and Week 4. Both groups showed greater maximal respiratory pressures at Week 2 and Week 4 than baseline. Both groups showed improved tongue pressure and geniohyoid muscle thickness at Week 4. In addition, the combined training group improved body trunk muscle mass, handgrip strength and five-time chair stand test, whereas the single training group did not. This study revealed that high-intensity inspiratory muscle training improved inspiratory muscle strength and swallowing muscle strength and mass. Moreover, inspiratory and abdominal muscle combined training showed an additional benefit of improving systemic muscle strength, mass and performance.

Exploring the Impact of Astaxanthin Supplementation in Conjunction with a 12-Week CrossFit Training Regimen on Selected Adipo-Myokines Levels in Obese Males.

Obesity is associated with an exacerbated metabolic condition that is mediated through impairing balance in the secretion of some adipo-myokines. Therefore, the objective of the present study was to explore the impact of astaxanthin supplementation in conjunction with a 12-week CrossFit training regimen on some selected adipo-myokines, insulin insensitivity, and serum lipid levels in obese males. This study is a randomized control trial design; 60 obese males were randomly divided into four groups of 15, including the control group (CG), supplement group (SG), training group (TG), and combined training and supplement group (TSG). The participants were subjected to 12 weeks of astaxanthin (AST) supplementation [20 mg/d capsule, once/d] or CrossFit training or a combination of both interventions. The training regimen comprised 36 sessions of CrossFit, each lasting 60 min, conducted three times per week. The metabolic indices, body composition, anthropometrical, cardio-respiratory, and also some plasma adipo-myokine factors, including decorin (DCN), activin A, myostatin (MST), transforming growth factor (TGF)-β1, and follistatin (FST), were examined 12 and 72 h before the initiation of the main interventional protocols, and then 72 h after the final session of the training protocol. There was no significant difference in the baseline data between the groups (p > 0.05). There were significant interactions between group x time for DCN (η2 = 0.82), activin A (η2 = 0.50), FST (η2 = 0.92), MST (η2 = 0.75), and TGFB-1 (η2 = 0.67) (p < 0.001 for all the variables). Significantly changes showed for DCN in TSG compared to TG and SG and also TG compared to SG (p = 0.0001); for activin A in SG compared to TG (p = 0.01) and TSG (p = 0.002); for FST in SG compared to TG and TSG (p = 0.0001), also in TSG compared to TG (p = 0.0001); for MST in SG, TG, and TSG compared to CG (p = 0.0001) and also in TSG compared to SG (p = 0.0001) and TG (p = 0.001); for TGFB-1 in SG, TG, and TSG compared to CG (p = 0.0001) and also TSG compared to SG (p = 0.0001) and TG (p = 0.001). The 12-week CrossFit training concurrent with AST supplementation reduced anthropometric and metabolic factors and also serum lipid levels while producing positive changes in body composition and cardiovascular factors. Increased FST and DCN and reduced activin A, MST, and TGF-β1 were other affirmative responses to both interventions.

Effects of continuous, interval, and combined training methods on middle- and long-distance runners’ performance

Introduction: Running performance is largely influenced by training methods, including Continuous, Interval, and combined training methods. However, which training method that best improves the performance has not been identified. Aim: This study was to investigate how training methods continuous, interval, and combined training affect distance running performance. Methods: A total of thirty (n=30) athletes from the Ethiopia Hotel Athletics Club were selected as subjects. The studies included trained runners without previous injuries. Interventions lasted at least 12 weeks, with participants allocated to Interval, Continuous or combined training groups. The athletes' performance was assessed through cooper 12 min run test, wall squat test and multiple sprint test using pre- and posttest interventions. MANOVA was performed using SPSS to determine the mean difference with 95% confidence intervals (CIS) between continuous, interval (CIS), and combined training, and the effect sizes were calculated. Results: All training methods significantly improved VO2max, strength endurance, and speed. Moreover, there was no significant difference between the interval and combined training during the VO2max test (MD = 0.2, P &gt; 0.1). There was no significant difference between continuous and interval training during the posttests VO2max test. During the wall squat test, there was no significant difference between the training methods (p &gt; 0.1). Moreover, there were no significant differences between the continuous and combined, training groups or between the interval and combined training groups at the level of the multiple sprint test (p = 1, MD = 0.53). However, there was a significant difference between the continuous and interval training groups on the multiple sprint test (P = 0.024, MD = -1.75), with an effect size was 0.356.Conclusion: Interval and combined training are better strategies than continuous training for improving athlete performance. Key words: Athletics, continuous, interval, combined training methods, performance

The Effect of Aerobic and Combined Training on Heart Function of Middle-ged Male Patients After Bilateral Femoral Artery Coronary Grafting

Background and Aims Cardiovascular diseases are among the most common causes of death in the world. The prevalence of cardiovascular diseases increases with older age. Using cardiac exercise training to rehabilitate the heart after heart disease creates functional and structural adaptations in the patient’s cardiovascular system, reducing mortality from related diseases. Therefore, this study aimed to investigate the effect of two aerobic and combined exercise training methods on heart function capacity in middle-aged male patients after bilateral femoral artery coronary bypass grafting surgery. Methods In this quasi-experimental study with a pre-test-post-test design, 68 middle-aged male patients (Mean±SD age: 56.19±1.26 years) were studied after bilateral femoral artery coronary bypass grafting surgery. The subjects were randomly and availably divided into 3 groups: Aerobic (n=20), combined exercise training (aerobic+resistance) (n=20), and control (n=28). The subjects in the intervention groups performed 8 weeks of training, 3 sessions per week. Each training session in the aerobic and combined groups was performed for 40 minutes with the intensity of 70-85% heart rate reserved and 60 minutes with the intensity of 40-80% of one repetition maximum for each patient. Levene’s test, multivariate analysis of variance (MANOVA), and Bonferroni statistical tests were used to analyze the obtained data at the significance level of P≤0.05. Results The one-way MANOVA test showed that functional capacity, ejection fraction and maximal oxygen consumption increased significantly after aerobic and combined exercise training compared to the control group (P&lt;0.05). However, the Bonferroni post hoc test showed no significant differences between functional capacity, ejection fraction, and maximal oxygen consumption at post-test levels in aerobic and combined exercise training groups (P&gt;0.05). Conclusion The findings of this study show that both aerobic and combined exercise training can improve the heart functional variables in middle-aged male patients after bilateral femoral artery coronary bypass grafting surgery, and these improvement levels appear to be independent of the types of training.

Effects of Pilates-Combined Training on the Improvement of Flexibility and Pain Relief in Elite Fencers

PURPOSE: This study aimed to examine the effects of incorporating Pilates into the training regimen of elite fencers, focusing on enhancing flexibility and alleviating pain commonly experienced in the sport.METHODS: Twenty-five collegiate male elite fencers were stratified into two groups: a fencing training group (FT, n = 12, age = 18.92 ± 1.08, weight = 71.78 ± 7.43 kg, body mass index [BMI] = 22.32 ± 2.09 kg/m2) and a fencing-Pilates combined training group (FPT, n = 13, age = 19.92 ± 0.64, weight = 70.97 ± 9.14 kg, BMI = 22.61 ± 1.71 kg/m2). Evaluations, including body composition; physical fitness factors; shoulder strength; and joint range of motion in the upper extremities, lower extremities, neck, and spine, were conducted before and after 12 weeks of the intervention. Additionally, examinations of pain catastrophizing and anxiety levels during competitive engagements were performed.RESULTS: There were no statistical differences in body composition, physical fitness factors, or upper-limb strength between the FT and FPT groups. However, the FPT group exhibited a notable enhancement in shoulder abduction of the upper limb when holding a sword, in contrast to the unchanged metrics observed in the FT group. The positive impact of Pilates-combined treatment on flexibility extended to the neck; waist; and lower extremities, such as hip flexion, hip extension, hip abduction, medial rotation, and ankle dorsiflexion, coupled with significant improvements in psychological aspects, such as pain relief and related competition anxiety.CONCLUSIONS: This study confirmed that Pilates-combined treatment can have a beneficial effect on improving flexibility and pain in fencers, and verified the effectiveness of Pilates as an auxiliary training method for elite fencers.

Functional and Combined Training Promote Body Recomposition and Lower Limb Strength in Postmenopausal Women: A Randomized Clinical Trial and a Time Course Analysis.

Encouraging healthy aging in postmenopausal women involves advocating for lifestyle modifications, including regular physical exercise like combined training (CT) and functional training (FT). Regarding this population, age-related alterations in body composition, such as decreased muscle mass and heightened adipose tissue, impact health. The aim of this study was to analyze the effects of FT and CT on body recomposition in postmenopausal women. About the methods, we randomly allocated 96 post-menopausal women to the FT, CT, or control group (CG). We measured body composition by bioimpedance and lower limb muscle strength by sit-to-stand test in five repetitions, respectively. The training protocol lasted 16 weeks, and we measured body composition and lower limb muscle strength every 4 weeks, totaling five assessments. Regarding results, we notice that both training groups increased lean mass from the 8th week of training. In addition, a reduction was observed in total fat percentage and an increase in appendicular lean mass from the 12th week of intervention. No differences were found for body mass. Furthermore, only the experimental groups increase muscle strength, starting from the 4th week of training. The conclusion was that FT and CT promote similar adaptations in body recomposition without affecting body mass in postmenopausal women.

Influence of Vertical-Oriented vs. Horizontal-Oriented Combined Strength Training in Young Basketball Players.

Sánchez-Sabaté, J, Gutiérrez, H, Marco-Contreras, LA, Younes-Egana, O, Gonzalo-Skok, O, and Piedrafita, E. Influence of vertical-oriented vs. horizontal-oriented combined strength training in young basketball players. J Strength Cond Res 38(7): 1280-1287, 2024-This study aimed to compare the effects of 8-week combined vertical-oriented vs. horizontal-oriented training interventions in basketball athletes. Eighteen highly trained U-16 basketball players participated in this study and were randomly assigned to either a combined vertical-oriented training group (CVG, n = 9) or a combined horizontal-oriented training group (CHG, n = 9). Bilateral and unilateral vertical jump height, unilateral horizontal jump distance, 5-m, 10-m, and 20-m sprint times, change-of-direction sprint times, and a limb symmetry index were among the measured performance variables. Combined strength training was performed twice a week for 8 weeks. CVG was compounded by the squat exercise (3 sets of 6-8 R at 30-45% 1 repetition maximum [1RM]), jump squats (2 sets of 6 R, at 5-12.5% body mass [BM]), and vertical jumps (3-4 sets × 6 R). CHG included the hip thrust exercise (3 sets of 6-8 R at 30-45% 1RM), sled towing sprints (2-3 R, at 5-12.5% BM), and sprints (3-4 R of 20-m). Within-group differences showed significant ( p < 0.05 and statistical power >80%) improvements in unilateral vertical jumping with the right leg after both training interventions. By contrast, only CHG improved 5-m, 10-m, and 20-m sprint times ( p < 0.05 and statistical power >80%). Significant effects were observed for CHG compared with CVG in 5-m, 10-m, and 20-m sprint times ( p < 0.05 and statistical power >80%). This study reinforces the importance of oriented-combined training based on force-vector specificity target, mainly in horizontal-oriented actions.

Effect of Combined Physical Exercise Training in Reducing Cardiovascular Risk Among Adults with Obesity: A Randomized Clinical Trial.

It is necessary to understand the relationship between different models of exercise periodization and the reduction of cardiovascular risk in adults with obesity. The aim of this study was to verify the effect of two periodization models of combined training on the cardiovascular risk of adults with obesity of both sexes. A randomized clinical trial was conducted with adults of both sexes with obesity. They were divided into three groups: control group (CG), non-periodized combined training group (NG), and combined training group with linear periodization (PG). The NG and PG groups underwent physical exercise training regimen for 16 weeks, in three weekly sessions of 60min each, with the volume and intensity equalized. Cardiovascular risk was measured by the overall Framingham risk score (FRS). Generalized estimation equations and individual responsiveness analyses were used, stratified by sex. A statistically significant reduction in FRS was observed only in men of the NG (pre: 2.50 ± 0.56; post: 0.50 ± 1.02; p-value = 0.001). There was no statistically significant intervention effect on the women's cardiovascular risk. It was found that, regardless of sex, subjects in the control group mostly presented results of increased cardiovascular risk. In contrast, those belonging to the exercise groups, if not reduced, at least stabilized the chances of suffering a cardiovascular event in the next ten years after 16 weeks of combined training. Sixteen weeks of non-periodized combined training were sufficient to reduce cardiovascular risk in men with obesity. Both periodization models were important to stabilize the risk of developing a cardiovascular disease in the next 10 years.

Combined Training Improves Gene Expression Related to Immunosenescence in Obese Type 2 Diabetic Individuals

ABSTRACT Purpose: The aim of this study was to investigate the effects of moderate combined training (CT) on both the gene expression of pro- and anti-inflammatory markers and senescence in the immune system in peripheral blood mononuclear cells (PBMCs) and subcutaneous adipose tissue (SAT) of obese middle-aged individuals with type 2 diabetes (T2D). Methods: Thirty obese individuals (50.2 ± 9.4 years; body mass index: 31.8 ± 2.3 kg/m²) with T2D underwent 16 weeks of a CT group [CT; aerobic (50–60% of VO2max) plus resistance (50-75% of 1RM) training; 3 times/week, 70 min/session; n = 16)] or a control group (CG, n = 14). Nutritional patterns, muscle strength (1RM), cardiorespiratory fitness (VO2max), waist circumference (WC), body composition (Air Displacement Plethysmograph) and blood collections for biochemical (serum leptin, IL-2, IL-4, IL-6, IL-10, TNF-α and anti-CMV) and molecular (gene expression of leptin, IL-2, IL-4, IL-6, IL-10, TNF-α, PD-1, P16ink4a, CCR7, CD28 and CD27 in PBMCs and SAT) analyses were assessed before (Pre) and after (Post) the 16 weeks of the experimental period. Results: Significant decreases were observed in WC and IL4, TNF-α, PD-1 and CD27 expression in PBMCs for CT. Furthermore, significant increases were observed in 1RM and VO2max for CT after the experimental period. Conclusion: Moderate CT contributed to a reduction in the gene expression of markers associated to chronic inflammation and immunosenescence in PBMCs of obese middle-aged individuals with T2D.

Effects of blood flow restriction training on muscle fitness and cardiovascular risk of obese college students.

Purpose: The aim of this study was to investigate the effect of blood flow restriction (BFR) combined with low-intensity resistance training (RT) on cardiovascular risk factors in obese individuals. Methods: Twenty-six male obese college students were recruited and randomly assigned to a control group (CON, n = 8), a low-intensity RT group (RT, n = 9), and a combined BFR training and low-intensity RT group (BFRT, n = 9). Results: The subjects in BFRT group showed significant reductions in body fat percentage and waist-to-hip ratio and a significant increase in lean mass and muscle mass; the peak torque, peak power, and endurance ratio of knee extensors and elbow flexors were significantly upregulated; the root mean square (RMS) for the medial femoral muscle, lateral femoral muscle and biceps significantly increased; the diastolic blood pressure (DBP) showed a significant decrease. The BFRT group also showed significant up-regulations in RMS of the difference between the adjacent R-R intervals (RMSSD), high-frequency power (HF) of parasympathetic modulatory capacity, the standard deviation of R-R intervals (SDNN) of overall heart rate variability (HRV) changes and low-frequency power (LF) of predominantly sympathetic activity. In addition, glycated hemoglobin (HbA1C), insulin resistance index (HOMA-IR) and fasting blood glucose (FBG) were all significantly downregulated in BFRT group. In parallel, low-density lipoprotein (LDL-C) significantly reduced while high-density lipoprotein (HDL-C) significantly increased in BFRT group. Conclusion: BFR combined with low-intensity RT training effectively improved body composition index, increased muscle mass, improved neuromuscular activation, enhanced muscle strength and endurance, which in turn improved abnormal glucolipid metabolism and enhanced cardiac autonomic regulation.

Hypoxic acclimatization training improves the resistance to motion sickness.

Vestibular provocation is one of the main causes of flight illusions, and its occurrence is closely related to the susceptibility of motion sickness (MS). However, existing training programs have limited effect in improving the resistance to motion sickness. In this study, we investigated the effects of hypoxia acclimatization training (HAT) on the resistance to motion sickness. Healthy military college students were identified as subjects according to the criteria. MS model was induced by a rotary chair. Experimental groups included control, HAT, 3D roller training (3DRT), and combined training. The Graybiel scores were decreased in the HAT group and the 3DRT group and further decreased in the combined training group in MS induced by the rotary chair. Participants had a significant increase in blood pressure after the rotary chair test and a significant increase in the heart rate during the rotary chair test, but these changes disappeared in all three training groups. Additionally, LFn was increased, HFn was decreased, and LF/HF was increased accordingly during the rotary chair test in the control group, but the changes of these three parameters were completely opposite in the three training groups during the rotary chair test. Compared with the control group, the decreasing changes in pupillary contraction velocity (PCV) and pupillary minimum diameter (PMD) of the three training groups were smaller. In particular, the binocular PCV changes were further attenuated in the combined training group. Our research provides a possible candidate solution for training military pilots in the resistance to motion sickness.

Effect of resourcefulness practice combined with mindfulness training on improving the symptoms of depression in patients after percutaneous coronary intervention

ObjectiveThis study aimed to explore the effect of resourcefulness and mindfulness training on depressive patients after percutaneous coronary intervention (PCI). MethodsThis single-center, randomized clinical trial was conducted. From October 2020 to August 2021, 132 depressive patients after PCI were selected from 4 wards of the cardiovascular department of a Class A tertiary hospital in Tangshan, China and divided into control group (CNG), resourcefulness practice group (RPG), mindfulness training group (MTG) and resourcefulness practice combined mindfulness training group (CMG). On the basis of routine nursing, the three intervention groups received resourecfulness practice, mindfulness training, and resourcefulness practice combined with mindfulness training for 12 weeks (1–6 weeks, once a week, 30 min each time; 7–12 weeks, practice three times a week and live on WeChat once a week, 30 min each time). The control group received routine nursing. Before the intervention, at 12 weeks and 24 weeks after the intervention, the Chinese version of the Cardiac Depression Scale, the Chinese Resourcefulness Scale, and the Five Facet Mindfulness Questionnaire were used to evaluate the depressive symptoms, the level of resourcefulness and the level of mindfulness among patients, respectively. ResultsA total of 132 patients completed the study (33 participants in each groups). After 12 weeks of intervention, the mixed effects model revealed that the level of resourcefulness and mindfulness were improved, and the depressive symptoms of patients were reduced in CMG as compared to CNG (the least square mean difference was −12.99, −37.19, 19.45, respectively, P < 0.01). Compared with the RPG, the level of mindfulness was improved, and the depressive symptoms were reduced in CMG (the least squares mean difference was −13.54, 10.99, respectively, P < 0.01). The level of resourcefulness of patients in CMG was higher than MTG (least squares mean difference was −8.37, P < 0.05). After 24 weeks of intervention, the level of mindfulness was improved, and the depressive symptoms were reduced in CMG, as compared to CNG (the least squares mean difference of the depressive symptoms and the level of mindfulness was −12.45, 13.03, respectively, P < 0.01) and RPG (the least squares mean difference was −7.79, 9.09, respectively, P < 0.05). Compared with the MTG, the depressive symptoms among patients were reduced in CMG (least squares mean difference was 7.37, P < 0.05). ConclusionResourcefulness practice combined with mindfulness training can be effective in reducing the symptoms of depression in patients after PCI, and the effects could last longer. Mindfulness training can supplement spiritual resourcefulness in resourcefulness practice.

Experimental research model from quantitative research was used in this study. This study sports infrastructure Antalyaspor the average age of 12,3±0,2 a year, training the average age of 3,5±0,7 with 12 years Combined Training Group (CTG) and the mean age of 12,2±0,1 years of training average age 4,0±0,7 year 12 Normal Training Group (NTG) to 24 male soccer player voluntarily participated. Before and after the 8-week training period, anthropometric measurement (length, width, circumference, subcutaneous fat), posture analysis, physiological tests; heart rate measurements, blood pressure, biomotoric tests; strength, sprint, flexibility, vertical jump, maximal strength (1RM), sit-ups, push-ups, standing long jump, jump rope, sit-reach, FutTech Technical tests (slalom, dribbling, passing, shooting, running), body temperature, ambient temperature and determination of perceived difficulty level tests were carried out. When the CTG and NTG pre-test and post-test data were examined, a statistically significant difference was found in the pre-test biomotoric tests in standing long jump, lat pull and FutTech time values (p&amp;lt;0.05). A statistically significant difference was found in the lat pully and abdominal values of the CTG and NTG end test values in the biomotanical tests (p&amp;lt;0.05). Based on the data we have obtained, it has been determined that combined training performed in children in the infrastructure contributes to the development of some biomotoric features and supports the development of football-specific technical skills compared to normal training programs.

The Effects of Combining Aerobic and Heavy Resistance Training on Body Composition, Muscle Hypertrophy, and Exercise Satisfaction in Physically Active Adults.

This study investigated the effects of combined aerobic and heavy resistance training on the variables of body composition, muscle hypertrophy, and exercise satisfaction in physically active adults in comparison with heavy resistance training only (predominantly designed for hypertrophy). Twenty-two healthy male adults between the ages of 18 and 35, who had limited previous experience with muscle resistance training, participated in the intervention program while maintaining their physical activity level. The participants were randomly allocated into two groups: the resistance training group (control group) and the combined training group (experimental group), which involved both resistance training and aerobic training. Aerobic training consisted of 30 min aerobic interval training sessions three times a week with a total of 8 min work bouts in each at 60-70% of heart rate reserve (HRR). The intervention training program lasted for eight weeks. Resistance training consisted of a 3-day muscle group split (2-3 exercises per muscle group, 8 sets per muscle group, 6-12 repetition maximum (RM). Upon completion, body composition, muscle hypertrophy, and exercise satisfaction were analyzed using the mixed-design ANOVA. Variables selected for this study as markers of body composition responded differently to the different interventions and time; however, some trends were not statistically significant. Overall, it is not possible to state unequivocally that one training modality was superior to another in the body composition cluster, for significant improvements were observed within the groups from pre- to post-interventions, but no significant differences were observed between the resistance training and combined training groups, while, both interventions showed improvement with time in some variables of muscle hypertrophy. Compared to baseline, the exercise satisfaction post-intervention improved within the groups. From pre- to post-testing, both resistance and combined training groups improved exercise satisfaction (p < 0.05 in both groups). However, there was no significant difference in exercise satisfaction observed between the resistance training and combined training groups after the training intervention (p > 0.05).

Evaluating the learning performances for CNC machine practice in mechanical engineering degree courses based on students’ mental workload

This study evaluates the performance of learning CNC machining in mechanical engineering degree programs by assessing students’ mental workload (MWL). Both subjective (NASA-Task Load Index) and objective (increasing ratio of heart rate, IRH) evaluation methods were employed to assess the MWL of 46 students randomly assigned to two groups: a traditional training group and a combined simulation training group. The results demonstrate the significant impact of the training method on students’ MWL. Specifically, the MWL and IHR values of the combined simulation training group were 54.3 and 9.2, respectively, while those of the traditional training group were 58.3 and 13.2. Additionally, the correlation analysis showed a significant correlation between the IHR value and the MWL score of NASA-TLX. These findings suggest that implementing simulated software and the combined simulation training method effectively reduces students’ MWL, thereby promoting active knowledge acquisition. Consequently, students’ MWL can be utilized to evaluate the effectiveness of technical education with the aim of enhancing training efficiency and quality.
