Efficacy of Repair for ACL Injury: A Meta ‑analysis of Randomized Controlled Trials
Int J Sports Med DOI: 10.1055/a-1755-4925We aim to compare the curative effect of primary repair for anterior cruciate ligament (ACL) injury with reconstruction and provide the reliable evidence for its clinical application. The literatures were searched in PubMed, EMBASE, Springer, and other medical literature databases published between January 1970 and June 2021. Basic characteristics, surgery technique, clinical outcome scores and physical examination results were recorded and evaluated. Seven randomized controlled trials (RCT) were eligible for inclusion. The...

Assessment of Peak Oxygen Uptake with a Smartwatch and its Usefulness for Training of Runners
Int J Sports Med DOI: 10.1055/a-1686-9068Peak oxygen uptake (˙VO2peak) is an important factor contributing to running performance. Wearable technology may allow the assessment of ˙VO2peak more frequently and on a larger scale. We aim to i) validate the ˙VO2peak assessed by a smartwatch (Garmin Forerunner 245), and ii) discuss how this parameter may assist to evaluate and guide training procedures. A total of 23 runners (12 female, 11 male; ˙VO2peak: 48.6±6.8 ml∙min−1∙kg−1) visited the laboratory twice to determine their ˙VO2pe...

Active Vegetarians Show Better Lower Limb Strength and Power than Active Omnivores
Int J Sports Med DOI: 10.1055/a-1753-1322Vegetarian diets have become popular among athletes and active individuals and can have advantages for physical performance, but the results are still conflicting regarding muscle strength and power. The aim of this study was to evaluate the diet and physical performance of vegetarians through tests of dynamic, isometric, and relative strength; muscle power; and aerobic capacity. In this cross-sectional study, 32 vegetarians and 26 omnivores, who were physically active, were evaluated for the Healthy Eating Index and perfor...

Muscle Oxygenation during Repeated Cycling Sprints in a Combined Hot and Hypoxic Condition
Int J Sports Med DOI: 10.1055/a-1495-5612The aim of the present study was to examine the effects of a combined hot and hypoxic environment on muscle oxygenation and performance during repeated cycling sprints. In a single-blind, counterbalanced, cross-over research design, 10 male athletes performed three sets of 3 × 10-s maximal pedaling interspersed with 40-s recovery between sprints under four different environments. Each condition consisted of a control (CON; 20°C, 20.9% FiO2), normobaric hypoxia (HYP; 20°C, 14.5% FiO2), hot (HOT; 35°C, 20.9% ...
