Eccentric exercise, particularly when novel and strenuous, can cause soreness and inflammation, impairing subsequent exercise performance. These performance decrements are attributable to oxidative stress and inflammation. Interestingly, a single bout of eccentric exercise can confer protective effects, ameliorating the negative consequences in subsequent bouts. This is termed the repeated bout effect (RBE), which would be of interest to athletes considering the detrimental effects of strenuous eccentric exercise. Athletes regularly consume supplements in hope of attenuating the performance decrements after strenuous eccentric exercise . However, considering the dose-response relationship between the initial performance decrement and the magnitude of the RBE , supplements may diminish the obtainment of the RBE. This notion remains untested, and so the proposed project is a double-blind, placebo-controlled, parallel group study aiming to assess the effects of acute vitamin C and ibuprofen supplementation on the development of the RBE. These two supplements were chosen as they are most frequently and successfully used in the literature to target oxidative stress (vitamin C) and inflammation (ibuprofen). Additionally, these doses (and the timing of supplements) were chosen to mimic protocols reporting beneficial effects

This is a double blind, randomised, placebo-controlled, parallel-group trial to evaluate the effect of Maolactin FMR supplementation on post exercise inflammation, exercise recovery and muscle fatigue and pain in an otherwise healthy population of adults 18-65 years old over 10 weeks with 8 weeks of supplementation. This is PART A of the study.

This study is a randomized, double-blind, placebo-controlled trial designed to examine the effects of pre-sleep creatine monohydrate supplementation on anaerobic performance and muscle damage markers in recreationally active females. Participants will be randomly assigned to receive either 5 grams of creatine monohydrate or a placebo 30 minutes before sleep for seven consecutive days. Anaerobic performance will be assessed using the Wingate Anaerobic Test, evaluating peak and average power output and fatigue index. Blood samples will be collected before and after the supplementation period to analyze markers of muscle damage, including creatine kinase and lactate dehydrogenase. This study aims to provide insight into the efficacy of short-term, time-specific creatine supplementation for enhancing performance and recovery.

After completing novel activity or exercise we may experience exercise-induced muscle damage (EIMD), resulting in a period of reduced muscle function and delayed onset muscle soreness (DOMS). DOMS is characterized by muscle pain and tenderness that typically resolves within a week. While the precise cause of DOMS is unknown, there is growing evidence implicating damage to the connective tissue that surrounds our muscle fibers and is related to a small amount of inflammation. This inflammation is a normal part of our body's ability to recovery from injuries and may be visualized through the use of ultrasound technology. A variety of recovery techniques have been proposed that may help with the recovery of DOMS such as massage and electrical muscle stimulation, but these are not always accessible. Therefore, we are interested in investigating whether the number of daily steps can affect how you experience DOMS.

Crossfit® is a training modality that consists in functional movements, constantly varied and executed at high intensity. Both training sessions and competitions involve physically demanding activities, which in addition to being performed at very high intensity also involves the aerobic metabolism pathway. These characteristics led to very high metabolic and muscular stress, as well as decrease in physical performance immediately after competitions and training sessions. The cumulative effects of the metabolic and muscular stress can be a precursor of injuries. Studies using different therapeutic modalities aiming to improve post-exercise recovery are needed in order to tackle this issue. Oxidative stress induced by exercise has been a research field in constant growth, due to its relationship with the processes of fatigue, decreased production of muscle strength, and its ability to cause damage to the cell. To the date there are no studies comparing the effects of different therapeutic modalities applied after an exercise session on functional performance, muscle damage, and oxidative stress in an exercise modality such as Crossfit®. Therefore, the aim of this project is to assess and compare the effects of different therapeutic modalities on functional performance, muscle damage, and oxidative stress of Crossfit® athletes.

Oral Melatonin is a commercially available product available alone and as a constituent in a number of supplements. Previous research suggests that short-term supplementation with oral melatonin may amplify the recovery response to damaging resistance exercise via modulation of subsequent immune and inflammatory responses. However the effects of oral melatonin on neutrophil and monocyte invasion/migration, a critical step in the resolution of skeletal muscle tissue homeostasis, has not been examined. An oral melatonin supplement (5mg) will be provided three times daily beginning 24-hours before and ending 48-hours after an acute bout of damaging resistance exercise (total 15mg/day for 3 days). Goals: 1. To investigate the effect of melatonin on systemic and cellular responses following an acute bout of damaging resistance exercise. 2. To investigate the effect of melatonin on measures of functional performance before and during recovery from an acute bout of damaging resistance exercise.

The goal of this clinical trial is to compare recovery in healthy, active runners. The main questions it aimed to answer were whether 7 day supplementation with Vistula TC attenuated: * muscle function * inflammation * soreness following a marathon run. Participants will either consume a spray-dried tart cherry supplement or a calorie-matched placebo-control for 7 days, and complete a marathon. Participants will perform functional tests, be assessed for their perceptual recovery and markers of inflammation and muscle damage via: * maximal voluntary contractions * counter movement jumps * visual analog scales to assess soreness * blood samples
