The effect of repeated sprints on immunological modulation and the role of fat-free mass, biological maturation and dietary inflammatory index in male athletes
Background Repeated sprint exercise (RSE) induces inflammation, which may be modulated by fat-free mass (FFM), biological maturation (BM), and dietary patterns, assessed by the Dietary Inflammatory Index (DII). Aim To examine the influences of FFM, BM, and DII on cytokine responses to RSE in male athletes. Methods A study with a quasi-experimental approach and cross-sectional design with a sample of 30 male athletes (20-adolescents, 10-adults). B…
A Practical Approach to Assessing Physical Freshness
Background: Monitoring physical freshness is essential in assessing athletes’ conditions during training periods, training sessions, or competitions. To date, no single physical freshness scale has been successfully validated against training load variables and widely used scales measuring different facets of physical freshness. Objective: In this study, we develop and test the practical utility of a perceived physical freshness (RPF) scale to mo…
Short-Term Effects of Low-Fat Chocolate Milk on Delayed Onset Muscle Soreness and Performance in Players on a Women’s University Badminton Team
This study investigated the short-term effects of low-fat chocolate milk (LFCM) consumption on delayed onset muscle soreness (DOMS) and performance in female badminton players. Seven female badminton players (23 ± 1 years; height: 163.8 ± 4.1 cm; body mass: 58.7 ± 0.9 kg) were randomly assigned to 1 week of LFCM (500 mL) or placebo (water, 500 mL) consumption in a crossover design. Participants consumed LFCM or water immediately after each traini…
The combination of cardiorespiratory fitness and muscular fitness, and prevalence of diabetes mellitus in middle-aged and older men
Background Although the negative relationship between cardiorespiratory fitness (CRF) or muscular fitness and diabetes mellitus were respectively observed in many previous studies, there is still a lack of studies that include CRF and muscular fitness simultaneously. Therefore, this study aimed to investigate the relationship between the combination of CRF and muscular fitness and diabetes through a cross-sectional study. Methods This study was p…
Effects of Endurance Training Intensity on Pulmonary Diffusing Capacity at Rest and after Maximal Aerobic Exercise in Young Athletes
This study compared the effects of varying aerobic training programs on pulmonary diffusing capacity (TL CO ), pulmonary diffusing capacity for nitric oxide (TL NO ), lung capillary blood volume (Vc) and alveolar-capillary membrane diffusing capacity (DM) of gases at rest and just after maximal exercise in young athletes. Sixteen healthy young runners (16-18 years) were randomly assigned to an intense endurance training program (IET, n = 8) or to…
Potential Improvement in Rehabilitation Quality of 2019 Novel Coronavirus by Isometric Training System; Is There “Muscle-Lung Cross-Talk”
The novel Coronavirus Disease 2019 (COVID-19) crisis is now present in more than 200 countries. It started in December 2019 and has, so far, led to more than 149, 470,968 cases, 3,152,121 deaths, and 127,133,013 survivors recovered by 28 April 2021. COVID-19 has a high morbidity, and mortality of 2%, on average, whereas most people are treated after a period of time. Some people who recover from COVID-19 are left with 20 to 30% decreased lung fun…
Wearable Inertial Measurement Unit to Accelerometer-Based Training Monotony and Strain during a Soccer Season
The purpose of this study was to analyze the intragroup differences in weekly training monotony (TM) and training strain (TS) between starter and non-starter male professional soccer players at accelerometry based variables throughout the periods of a season. TM and TS of different accelerations and decelerations zones for twenty-one players were followed for forty-eight weeks. Regardless of group, players obtained the highest mean TM (starters =…
Exercise in an Overweight Patient with Covid-19
Coronavirus (COVID-19) is a dangerous infectious disease that is easily transmitted and which is called an acute respiratory syndrome. With the spread of the coronavirus around the world and its epidemic among humans, we are losing many humans. The long process of treatment in hospitalized patients who are receiving intensive care and medication is associated with physical weakness. It has been suggested that lifelong exercise can create a safe m…
Effects of Unloaded vs. Ankle-Loaded Plyometric Training on the Physical Fitness of U-17 Male Soccer Players
The aim of this study was to compare the impact of two differing plyometric training programs (loaded plyometrics (with 2.5% of body mass placed above the ankle joint) vs. unloaded plyometrics), performed biweekly for 10 weeks, on the physical fitness of elite junior male soccer players. Participants aged 16.0 ± 0.5 years were randomly assigned between unloaded plyometrics (UP; n = 12), loaded plyometrics (LP; n = 14) and control (C; n = 12) grou…
Effects of Ramadan Intermittent Fasting on Gut Hormones and Body Composition in Males with Obesity
We studied the effects of Ramadan intermittent fasting (RIF) on gut hormones (leptin, glucagon-like peptide-1 (GLP-1), peptide YY (PYY), cholecystokinin (CCK), and ghrelin) in males with obesity. Thirty sedentary males were randomly allocated to either an experimental group (EG, n = 15) or a control group (CG, n = 15). The EG group completed their Ramadan fasting rituals (30 days), whereas the CG continued with their normal daily habits. Blood sa…
The effects of attention retraining on depressive mood and cortisol responses to depression‐related stimuli 1
Although it has been reported that attentional bias at an early stage is found in depression, no study has investigated the effects of modification of attentional bias at an early stage on depressive mood and cortisol response to a stressor. Therefore, this study tested the hypotheses that the modification of attentional bias at an early stage would reduce depressive mood and cortisol response. Fifty‐three participants were allocated alternately …
Effect of Cold Acclimation on Antioxidant Status in Cold Acclimated Skaters
We investigated whether cold acclimation leads to increased activity of the antioxidant defense enzymes and muscle injury. Comparisons were between short track skaters (n=6) and inline skaters (n=6) during rest and at submaximal cycling (65% VO2max) in cold (ambient temperature: 5+/-1 degrees C, relative humidity: 41+/-8%) and warm conditions (ambient temperature: 21+/-1 degrees C, relative humidity: 35+/-5%), during 60 min, respectively, and dur…
Comparison of Metabolic Substrates between Exercise and Cold Exposure in Skaters
To test the effect of a cold condition on metabolic substrate and possible development of muscle injuries, short track skaters (n=9) and inline skaters (n=10) took rest and submaximal cycled (65% V(.)O2max) in cold (ambient temperature: 5+/-1 degrees C, relative humidity: 41+/-8%) and warm conditions (ambient temperature: 21+/-1 degrees C, relative humidity: 35+/-5%), for 60 min, each. Blood glucose (BG), triglyceride (TG), free fatty acid (FFA),…
