The Effect of Dietary Supplements on Endurance Exercise Performance and Core Temperature in Hot Environments: A Meta-analysis and Meta-regression.

Sports Med 2021 Jun 15. Epub 2021 Jun 15.

A-STEM Centre, College of Engineering, Swansea University, Swansea, UK.

Background: The ergogenic effects of dietary supplements on endurance exercise performance are well-established; however, their efficacy in hot environmental conditions has not been systematically evaluated.

Objectives: (1) To meta-analyse studies investigating the effects of selected dietary supplements on endurance performance and core temperature responses in the heat. Supplements were included if they were deemed to: (a) have a strong evidence base for 'directly' improving thermoneutral endurance performance, based on current position statements, or (b) have a proposed mechanism of action that related to modifiable factors associated with thermal balance.

Chronobiol Int 2021 Jun 15:1-12. Epub 2021 Jun 15.

Laboratory Physical Activity Impact on Health (IAPS), Toulon University, Toulon, France.

This study compares the effectiveness of a 12-week moderate exercise training program (METP), performed in the morning versus the evening, on sleep, physical activity, physical fitness, sleepiness, fatigue and health-related quality of life (HRQoL) in overweight and obese patients. Sedentary and inactive overweight/obese adults (n = 36) were included in METP and randomized into two groups: morning group (GM) and evening group (GE).

Real-Time Estimation of Aerobic Threshold and Exercise Intensity Distribution Using Fractal Correlation Properties of Heart Rate Variability: A Single-Case Field Application in a Former Olympic Triathlete.

Front Sports Act Living 2021 28;3:668812. Epub 2021 May 28.

College of Medicine, University of Central Florida, Orlando, FL, United States.

A non-linear heart rate variability (HRV) index based on fractal correlation properties called alpha1 of Detrended Fluctuation Analysis (DFA-alpha1), has been shown to change with endurance exercise intensity. Its unique advantage is that it provides information about current absolute exercise intensity without prior lactate or gas exchange testing. Therefore, real-time assessment of this metric during field conditions using a wearable monitoring device could directly provide a valuable exercise intensity distribution without prior laboratory testing for different applied field settings in endurance sports.

Plasma Activin A and Decorin in Exercised Purebred Arabian Horses - Preliminary Study.

J Equine Vet Sci 2021 Jul 28;102:103638. Epub 2021 Apr 28.

Department of Horse Breeding and Use, Faculty of Animal Science and Bioeconomy, University of Life Sciences in Lublin, Lublin, Poland.

Development of the musculoskeletal system occurs, in part, through an impact on regulatory proteins, such as activin A and decorin. Activin A induces atrophic effects on skeletal muscle, and decorin regulates the formation of connective tissue proteins like collagen and elastin in tendons and ligaments. The aim of this study was to evaluate the influence of different intensities of exercise on blood plasma activin A and decorin concentrations in horses. Read More

Circulating MicroRNA Responses to Postprandial Lipemia with or without Prior Exercise.

Int J Sports Med 2021 Jun 11. Epub 2021 Jun 11.

Department of Kinesiology, University of Maryland School of Public Health, College Park, United States.

Repeated exposure to a high-fat meal triggers inflammation and oxidative stress, contributing to the onset of cardiometabolic diseases. Regular exercise prevents cardiometabolic diseases and a prior bout of acute endurance exercise can counteract the detrimental cardiovascular effects of a subsequent high-fat meal. Circulating microRNAs (ci-miRs) are potential mediators of these vascular effects through regulation of gene expression at the posttranscriptional level. Read More

Blood Flow Restriction Training for the Shoulder: A Case for Proximal Benefit[Formula: see text].

Am J Sports Med 2021 Jun 10:3635465211017524. Epub 2021 Jun 10.

Orthopedic Biomechanics Research Laboratory, Department of Orthopedics and Sports Medicine, Houston Methodist Hospital, Houston, Texas, USA.

Background: Although blood flow restriction (BFR) is becoming increasingly popular in physical therapy and athletic training settings, little is known about the effects of BFR combined with low-intensity exercise (LIX) on muscles proximal to the site of occlusion.

Hypothesis/purpose: Determine whether LIX combined with BFR applied distally to the shoulder on the brachial region of the arm (BFR-LIX) promotes greater increases in shoulder lean mass, rotator cuff strength, endurance, and acute increases in shoulder muscle activation compared with LIX alone. We hypothesized that BFR-LIX would elicit greater increases in rotator cuff strength, endurance, and muscle mass. Read More

Astaxanthin supplementation enhances metabolic adaptation with aerobic training in the elderly.

Physiol Rep 2021 Jun;9(11):e14887

Department of Radiology, University of Washington, Seattle, WA, USA.

Endurance training (ET) is recommended for the elderly to improve metabolic health and aerobic capacity. However, ET-induced adaptations may be suboptimal due to oxidative stress and exaggerated inflammatory response to ET. The natural antioxidant and anti-inflammatory dietary supplement astaxanthin (AX) has been found to increase endurance performance among young athletes, but limited investigations have focused on the elderly.

The Epidemiology, Risk Factors, and Nonsurgical Treatment of Injuries Related to Endurance Running.

Curr Sports Med Rep 2021 Jun;20(6):306-311

Sea Mar Community Health Centers, Seattle, WA.

Abstract: Running is a popular form of exercise that is easily accessible to various populations; endurance running, defined as distances beyond 5 km, continues to grow within the sport. Endurance running-related injuries are common in the lower extremities and are primarily overuse related. A multitude of risk factors for injury exist, including extrinsic factors, such as running distance and frequency, and intrinsic factors, such as biomechanics and nutrition status. Read More

Effect of hypoxia and nitrate supplementation on different high-intensity interval-training sessions.

Eur J Appl Physiol 2021 Jun 7. Epub 2021 Jun 7.

ISSUL, Institute of Sport Sciences and Physical Education (ISSEP), University of Lausanne, Lausanne, Switzerland.

Purpose: To test the hypothesis that interval-training (IHT) would be impaired by hypoxia to a larger extent than repeated-sprint training (RSH) and that dietary nitrate (NO) would mitigate the detrimental effect of hypoxia to a larger extent during IHT than RSH.

Methods: Thirty endurance-trained male participants performed IHT (6 × 1 min at 90%∆ with 1 min active recovery) and RSH (2 sets of 6 × 10 s "all-out" efforts with 20 s active recovery) on a cycle ergometer, allocated in one of three groups: normobaric hypoxia (~ 13% FO) + NO - HNO, n = 10; normobaric hypoxia + placebo - HPL, n = 10; normoxia (20.9% FO) + placebo - CON, n = 10.

Moderate endurance training reduced hepatic tumourigenesis associated with lower lactate overload compared to high-intensity interval training.

Clin Exp Pharmacol Physiol 2021 Jun 6. Epub 2021 Jun 6.

Key Laboratory of Adolescent Health Assessment and Exercise Intervention of Ministry of Education, East China Normal University, Shanghai, China.

The anti-tumour effects of exercise are still poorly understood. In recent years, high-intensity interval exercise has been recognised as one of the best choices for better health. However, high-intensity interval exercise induces lactate production in muscles and elevates blood lactic acid levels, and the resulting acidic microenvironment may promote tumour progression.
