Article Synopsis
- The study aimed to assess how repeated cold-water immersion (CWI) affects performance and perceptions in adolescent swimmers during a training week.
- Twenty competitive swimmers participated in a randomized crossover study where they experienced three interventions: CWI, thermoneutral water immersion (placebo), and passive recovery, with a focus on swim performance, flexibility, power, and perceived well-being.
- Results showed improvements in swim performance over time for all interventions, but no significant differences in pain or tiredness among them, with a preference for CWI and thermoneutral immersion expressed by the athletes.
This study aimed to investigate the effects of repeated massage adjusted for swimmers' training on the perceptive, functional, and performance outcomes of a sprint. We also investigated the effects of a single short massage on swimmers' self-reported perceptions after resistance training. This cross-over randomized controlled trial with concealed allocation, assessor blinding, and intention-to-treat analysis included 19 male and female competitive swimmers between 12 and 20 years old.

- The study aimed to evaluate the effectiveness of cold-water immersion (CWI) in reducing muscle soreness, focusing on various factors such as immersion time, water temperature, and type of exercise.
- It included a systematic review and meta-analysis of 44 randomized controlled trials that compared CWI with control conditions, revealing CWI's superiority in reducing soreness for immediate effects across many situations.
- The findings concluded that while CWI is beneficial for muscle soreness management, its effectiveness is more pronounced with short to medium immersion times, especially after endurance exercises for immediate results.
Photobiomodulation therapy applied during an exercise-training program does not promote additional effects in trained individuals: A randomized placebo-controlled trial.

Background: Previous studies have shown positive results of photobiomodulation (PBM) for improving performance and accelerating post-exercise recovery. However, the effects of PBM in healthy individuals who underwent a neuromuscular adaptation training remain unclear.
Objective: To investigate the effects of PBM during a training program combining sprints and explosive squats exercises on clinical, functional, and systemic outcomes in trained healthy individuals compared to a placebo intervention and a control.
Muscle strength assessment is fundamental to track the progress of performance and prescribe correct exercise intensity. In field settings, simple tests are preferred. This study develops equations to estimate maximal muscle strength in upper- and lower-extremity muscles based on submaximal elastic resistance tests.

A new mathematical approach to explore the post-exercise recovery process and its applicability in a cold water immersion protocol. J Strength Cond Res 33(5): 1266-1275, 2019-The objective of this study was to propose a mathematical model to analyze the post-training recovery of perceptive, functional, metabolic, and autonomic parameters from the use of cold water immersion (CWI) through isolated and combined analysis.

To compare the effects of resistance training with elastic devices (tubes and Thera-Bands) and conventional devices (weight machines and dumbbells) on the outcome muscular strength. A search was performed in the databases PubMed/MEDLINE, EMBASE, PEDro (Physiotherapy Evidence Database), and CENTRAL (Cochrane Central Register of Controlled Trials) from the earliest records up to 20 December 2017.

One alternative that has recently increased in popularity is the use of elastic tubes, which stand out for being easy to handle, low cost, practical, and feasible.
Objective: Analyze the test-retest reliability of the knee extensors muscle fatigue resistance test (FRT) with elastic tubes.
Objective: The main focus of this systematic review was to determine the efficacy of phototherapy in the management of creatine kinase (CK) activity after exercise and furthermore to identify for which exercise model protocol phototherapy provides the best results.
Design: Meta-analysis comparing phototherapy with a control condition.
Setting: The MEDLINE, EMBASE, SPORTDiscus, PEDro, and CENTRAL databases were searched from their earliest records to October 03, 2016.
Article Synopsis
- * The study analyzed data from over 10,000 Danish workers and found that higher fatigue levels correlated with lower durations of high-intensity leisure-time exercise.
- * Older workers are significantly less active than younger ones, suggesting that employers should implement more opportunities for physical activity during work hours to help mitigate fatigue and improve overall health.
Effect of low-level laser therapy (LLLT) and light-emitting diodes (LEDT) applied during combined training on performance and post-exercise recovery: protocol for a randomized placebo-controlled trial.

Background: Previous studies have shown positive results of phototherapy for improving performance and accelerating recovery; however, the effects of phototherapy during training and after a primary adaptation remain unclear. The aim of this randomized controlled trial is to analyze the effects of phototherapy and combined training on clinical, functional, and psychological outcomes and on vascular endothelial growth factor.
Methods: This randomized placebo-controlled trial by stratified sample will involve 45 healthy male participants.
Background: Cold water immersion (CWI) is a technique commonly used in post-exercise recovery. However, the procedures involved in the technique may vary, particularly in terms of water temperature and immersion time, and the most effective approach remains unclear.
Objectives: The objective of this systematic review was to determine the efficacy of CWI in muscle soreness management compared with passive recovery.
