Effects of hyperbaric oxygen therapy on exercise-induced muscle damage.

Purpose: To perform a literature review on hyperbaric oxygen (HBO2) therapy as a treatment for exercise-induced muscle damage (EIMD). Methods: PubMed, Web of Science and Google Scholar were searched for articles related to HBO2 therapy as a treatment for exercise-induced muscle damage. Inclusion criteria included HBO2 therapy as the primary intervention to treat EIMD. Articles used in this review ranged from 1995-2021. Conclusion: Current literature on the effectiveness of HBO2 therapy to treat EIMD is mixed. Early and frequent treatments seem to be important factors when it comes to the success of HBO2 therapy. Additional research is needed to determine if HBO2 therapy has potential to treat more severe forms of EIMD and the role HBO2 therapy has on inflammation and satellite cell function after EIMD.

The Impact Plant-Based Diets Have on Athletic Performance and Body Composition: A Systematic Review.

Plant-based diets have gained popularity among athletes in recent years. Some believe that plant-based diets will improve performance owing to higher intakes of carbohydrates and antioxidants. Some believe it that will harm performance due to lower intakes of complete protein and creatine. This systemic review was conducted using Covidence software. A literature search of PubMed, Embase (Elsevier), CINAHL Plus (EBSCO), and Web of Science was completed on 22 March 2022. Following the development of clear objectives and a research question that identified the population, intervention, comparison, and outcomes, initial search criteria and keywords were identified. Extracted results totaled 2249, including 797 duplicates. The initial screening resulted in 1437 articles being excluded. The remaining 15 articles proceeded to full-text screening. A final 8 articles were included in the review, with 7 excluded. This paper will review the impact plant-based diets have on athletic performance and body composition in healthy young adults aged 18 to 45 years.

Following a plant-based diet does not harm athletic performance.Plant-based diets may improve maximal oxygen consumption, vertical countermovement jumps, and relative strength.There is no evidence that plant-based diets are detrimental to athletic performance or body composition.The long-term implications and the affect following a plant-based diet has on athletic performance in professional athletes are still unknown.

Recovery after Exercise-Induced Muscle Damage in Subjects Following a Vegetarian or Mixed Diet.

It is unclear if following a vegetarian diet affects muscle recovery after exercise-induced muscle damage (EIMD). Sixteen vegetarians (VEG) and sixteen mixed dieters (MIX) performed a vertical jump, quadriceps femoris maximal isometric, and isokinetic concentric strength tests prior to and five days following the EIMD protocol. The quadriceps muscle was injured by performing eccentric contractions. Diet: MIX consumed more g/kg of animal protein (p < 0.001) and EAA (p < 0.05) except for isoleucine. VEG consumed more plant protein (p = 0.001). Isometric strength: MIX recovered post-day 2, VEG recovered post-day 4 (group (p = 0.07), time (p < 0.001)). Concentric contractions at 60 degrees per second: Both recovered post-day 1 (group (p = 0.27), time (p = 0.05)); 180 degrees per second: MIX recovered post-day 2, VEG recovered post-day 5 (group (p = 0.10), time (p < 0.001)); and 240 degrees per second: MIX recovered post-day 1, VEG did not recover by post-day 5 (group (p = 0.01), time (p < 0.001)). Vertical jump: Both recovered post-day 3 (group (p = 0.45), time (p < 0.001)). MIX recovered isometric strength 2 days faster, concentric strength was up to 5 days faster, and soreness was 1-4 days faster when compared to VEG. Both groups had similar recovery time for power.
