In this research project, we want to investigate whether the combined intake of proteins and tea extract has an influence on muscle regeneration compared to the sole intake of proteins or a placebo product. In the study, you will be randomly assigned to one of 3 groups. Neither the research group nor you will know which group you are assigned to. The study lasts 5 days for you as a participant. During these 5 days you will have to attend a total of 5 appointments in our laboratory. The groups differ only in the intake of the regeneration product, otherwise all measurements and appointments are identical. You will jog downhill for 30 minutes on the first day in order to strain your muscles. In order to be able to draw conclusions about the regeneration of your muscles, we will carry out the following measurements on all 5 days: Blood sampling at the fingertip, ultrasound of the thigh muscle, pain tolerance of the thigh muscle, strength tests of the thigh muscle, muscle function of the thigh muscle and jumping performance.

The purpose of this study is to evaluate the efficacy of a multi-ingredient recovery supplement . The research will focus on strength recovery and performance maintenance assessing reductions in soreness and inflammation, as well as muscle repair and damage mitigation. By investigating these key recovery metrics, this study aims to investigate the efficacy of this supplement as a solution for active individuals seeking to optimize post-exercise recovery.

Purpose: This study compared two recovery methods-transcutaneous electrical nerve stimulation (TENS) and foam rolling (FR)-for muscle recovery after intense exercise in elite female volleyball players. Background: Delayed-onset muscle soreness (DOMS) is common after intense training and can reduce athletic performance. TENS uses mild electrical currents applied through the skin to reduce pain and improve blood flow. Foam rolling uses a cylindrical device to apply pressure to muscles. Both methods are widely used by athletes, but no previous study has directly compared them in elite female volleyball players. Participants: Thirty elite female volleyball players from Iran's Premier League, aged 18-28 years, with at least five years of competitive experience. Procedures: Participants completed a demanding lower-body exercise protocol designed to induce muscle soreness. They were then randomly assigned to one of three groups: TENS group: received electrical stimulation to thigh muscles for 20 minutes Foam rolling group: performed self-massage with a foam roller for 20 minutes Control group: rested quietly for 20 minutes Interventions were applied 30 minutes after exercise and repeated 24 hours later. Outcomes Measured: Blood marker of muscle damage (creatine kinase \[CK\]) Vertical jump height Anaerobic sprint power Muscle soreness Measurements were taken before exercise and at 1, 24, and 48 hours afterward. Hypothesis: Both active recovery methods would reduce muscle damage markers and preserve jumping ability better than passive rest, with TENS potentially providing faster benefits.

The goal of this interventional study is to observe the effects of bone marrow stem cell behavior in skeletal muscle of women between 60 to 75 years old after a single moderate resistance exercise session. Plant sterol Rg1, a compound known to enhance stem cell infiltration following exercise in young men will be tested against a placebo in a double blinded crossover design. The main questions to be answered are: * Does Rg1 supplementation alter serum sex hormone levels in recovery from exercise? * Does Rg1 supplementation influence bone marrow stem cell differentiation in skeletal muscles of older women? Participants will: * Pre-test body composition, maximal leg strength, blood and muscle tissue. * One hour after taking the supplement, participants will perform 4 sets of 10 repetitions of 70% of maximal strength (1RM) leg press and have two thigh muscle biopsies (0 and 24 h after exercise). * Repeat the protocol one month later on the alternative supplement. Researchers will understand whether Rg1 improves recovery response to resistance exercise in post-menopausal women.

The purpose of this study is to evaluate the effect of NMN supplementation (250 and 500 mg/day over 38 days) compared to placebo in healthy volunteers with moderate physical activity on muscle recovery, physical capacity, cardiorespiratory recovery, the perception of the arduousness of the effort, the variation in blood lactate levels before and after physical exercise, the perception of the intensity of post-exercise muscle pain (cramps), the body composition and Nicotinamide-Adenine Mononucleotide (NAD+) level in blood.

Photobiomodulation therapy (PBMT) has recently been used to alleviate postexercise muscle fatigue and enhance muscle recovery, demonstrating positive results. A previous study by the investigator's research group demonstrated the optimal dose and the optimal output power (100 mW) for an infrared wavelength (810 nm). However, the effects of optimized PBMT on performance and post-exercise recovery in high-level soccer players, to date have not been evaluated. The present research project aims to evaluate the effects of PBMT (using low-level laser therapy) applied before a progressive running test on functional, muscle damage, inflammatory and oxidative stress markers in high-level soccer players.

Muscle fatigue and muscle recovery after exercise are recent areas of research involving Low Level Laser Therapy (LLLT) and many factors remain unknown, such as optimal doses, power and application parameters, mechanisms of action, effects on long-term exercise and the long-term effects on skeletal muscle recovery. The present research project aims to assess the effects of long-term recovery of LLLT in skeletal muscle after exercise and identify the optimal dose application of LLLT. After defining the best dose of application, we recruited two groups which will be irradiated with different power, 100mW and 400mW in order to seek the optimal parameter of low level laser therapy in performance. The investigators believed that the Low Level Laser Therapy can delay the physiological process of muscle fatigue, reduce injury or skeletal muscle microdamage arising from physical effort and accelerate muscle recovery after exercise.
