Arthroscopic Repair Versus Conservative Treatment for First-time Anterior Shoulder Dislocation
Int J Sports Med DOI: 10.1055/a-1982-3624To systematically compare the clinical efficacy of conservative treatment and arthroscopic one-stage repair for patients with first-time anterior dislocation of the shoulder. A retrieval and systematic review of randomized controlled studies of primary anterior shoulder dislocation with conservative versus arthroscopic repair was conducted and further pooled analysis was performed to compare the overall difference in clinical outcomes, including redislocation and revision surgery rates, shoulder function scores and related ...

Reliability of Biomarkers of Physiological Stress at Rest and Post-exertional Heat Stress
Int J Sports Med DOI: 10.1055/a-1890-0993The purpose of this study was to assess the reliability of blood biomarkers that can signify exercise-induced heat stress in hot conditions. Fourteen males completed two heat stress tests separated by 5–7 days. Venous blood was drawn pre- and post- heat stress for the concentration of normetanephrine, metanephrine, serum osmolality, copeptin, kidney-injury molecule 1, and neutrophil gelatinase-associated lipocalin. No biomarker, except copeptin, displayed systematic trial order bias (p≥0.05). Normetanephrine, ...

Prescription of High-intensity Aerobic Interval Training Based on Oxygen Uptake Kinetics
Int J Sports Med DOI: 10.1055/a-1929-0295Endurance training results in diverse adaptations that lead to increased performance and health benefits. A commonly measured training response is the analysis of oxygen uptake kinetics, representing the demand of a determined load (speed/work) on the cardiovascular, respiratory, and metabolic systems, providing useful information for the prescription of constant load or interval-type aerobic exercise. There is evidence that during high-intensity aerobic exercise some interventions prescribe brief interval times (...

Int J Sports Med DOI: 10.1055/a-1960-2543The purpose of this study was to evaluate changes in health-related parameters caused by the administration of anabolic-androgenic steroids and “fat-burning drugs” during a 6-month competition preparation period. The physiological, biochemical, and anthropometric parameters studied included serum cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, aspartate aminotransferase, alanine transaminase, bilirubin, body mass, and percentage of total body fat. Changes in ...

Jump and Sprint Performance Directly and 24  h After Velocity- vs. Failure-based Training
In conclusion, the non-failure-based VL10 impairs jump and sprint performance less than the failure-based TRF approach, despite matched volume and intensity.

Relative Energy Deficiency in Sport (RED-S) in Adolescents – A Practical Review
Int J Sports Med DOI: 10.1055/a-1947-3174There are many immediate and longer-term physical, psychological and metabolic benefits of being active during adolescence. These benefits exist when exercise and physical activity are undertaken in a state of energy balance. When exercise occurs in an environment of low energy availability, this is currently termed relative energy deficiency in sport and there are potential significant negative effects on mental well-being, bone, endocrine and metabolic health. Therefore, relative energy deficiency in sport may present to ...

Epidemiology of the injuries sustained by elite Spanish under-18 and under-20 rugby players
This study examine the injuries suffered by players (n=166) of the Spanish national men’s under-18 and under-20 rugby teams between 2015 and 2017, and identifies the actions involved in their appearance. All injuries (total n=78) sustained during matches and training were recorded as recommended by World Rugby, and injury incidence rates per 1000 player-hours (ph) calculated for both types of activity. Injuries occurred more commonly during matches than during training (incidence 105.3 [95%CI 78.7-131.9] per 1000 [ph] of match play, vs. 1.16 [95%CI0.69-1.62] per 1000 ph of training), and most days absent per 1000 ph duri...

Retrograde Training: Effects on Lower Body Strength and Power
Int J Sports Med DOI: 10.1055/a-1796-7808Backward walking and running on positive grades (retrograde training) represents a closed kinetic chain exercise used by rehabilitation specialists for patellofemoral-related injuries. To date, no longitudinal studies exist to support it use. This investigation examined the effects of retrograde training on lower body strength and power in recreational athletes aged 18–50 years over 6 weeks. Thirty-seven subjects were divided into two groups. Group 1 performed retrograde training 3 days∙wk−1 using treadmill ...

Both Hypoxia and Hypobaria Impair Baroreflex Sensitivity but through Different Mechanisms
Int J Sports Med DOI: 10.1055/a-1960-3407Baroreflex sensitivity (BRS) is a measure of cardiovagal baroreflex and is lower in normobaric and hypobaric hypoxia compared to normobaric normoxia. The aim of this study was to assess the effects of hypobaria on BRS in normoxia and hypoxia. Continuous blood pressure and ventilation were recorded in eighteen seated participants in normobaric normoxia (NNx), hypobaric normoxia (HNx), normobaric hypoxia (NHx) and hypobaric hypoxia (HHx). Barometric pressure was matched between NNx vs. NHx (723±4 mmHg) and HNx vs. HHx ...
