Published: Jan. 14, 2025

Objective Sleep is the most efficient means of recovery for athletes, guaranteeing optimal athletic performance. However, many athletes frequently experience sleep problems. Our study aims to describe sleep-wake patterns fencing and determine whether factors, such as sex, competitive level training schedules, could affect rhythm. Methods data from 23 were collected using Huawei Band 6, monitoring key parameters bedtime, wake time, duration deep light sleep, periods, REM duration, nap duration. During this period, required wear band continuously 24 hours daily, except bathing, charging, competition times.

Enhanced physical performance, attention, and mood states after a nap opportunity following a sleep restriction night in female athletes: A randomized controlled trial

Journal of Sports Sciences, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 13

Published: Feb. 18, 2025

This study examined the effects of two nap durations (40 minutes (N40) and 90 (N90)) on physical performance, sleepiness, attention, mood states (Profile Mood States, POMS), perceived exertion (RPE), pain perception (PP), recovery (PRS), delayed onset muscle soreness (DOMS) in well-trained women. Fourteen female boxers underwent digit cancellation test, POMS, 5-meter shuttle run test (5mSRT) under no-nap (N0), N40, N90 conditions after either normal sleep (NSN) or restriction (SRN). RPE PP were assessed immediately post-5mSRT, while PRS DOMS recorded at 5 min 24 h post-5mSRT. Total distance (TD) higher (HD) better N40 NSN compared to SRN (p < 0.05). Fatigue index (FI) was lower than N0, improved RPE, DOMS, decreased significantly with showing greater benefits POMS scores outperforming Overall, provided enhancing recovery, mood, reducing exertion, pain, both SRN.

Effect of daily mindfulness fluctuations on sleep and recovery-stress states in elite level judoka: an observational study

Frontiers in Sports and Active Living, Journal Year: 2025, Volume and Issue: 7

Published: April 24, 2025

Sleep is a fundamental factor in an athlete's ability to sustain peak performance and endurance. Mindfulness, defined as state of intentional, non-judgmental awareness the present moment, has been linked positive effects on sleep. The study aims investigate which recovery sleep parameters are influenced by interindividual differences mindfulness tendencies intraindividual daily fluctuations mindfulness. A two-week continuous monitoring was conducted with 33 elite-level judoka (17 female, 16 male; age: M = 23.79, SD 3.05) competing at national international level. Data collection included objective via actigraphy subjective through morning evening self-report questionnaires. analyzed function both trait mindfulness, well behavioral factors such number training sessions, session intensity, implementation activities naps. Multilevel analyses revealed significant associations between qualitative parameters, recovery-stress states. Among facets, acting emerged strongest predictor. In terms quantitative latencies. findings suggest that may play key role regulation among athletes, particularly enhancing perceived restfulness, improving states morning, facilitating process falling asleep. These results highlight promising target for interventions aimed reducing onset latencies mindful behaviors. Furthermore, underscores relative independence suggesting they distinct factors.

Post-Lunch Napping as a Strategy to Enhance Physiological Performance and Cognitive Function in Elite Volleyball Players

Medicina, Journal Year: 2024, Volume and Issue: 60(10), P. 1698 - 1698

Published: Oct. 16, 2024

Background and Objectives: Volleyball demands high levels of anaerobic strength, flexibility, agility, mental focus. Adequate sleep has been shown to enhance athletic performance cognitive function. This study investigates the impact post-lunch naps varying durations (25 45 min) on physiological focus elite volleyball players. Materials Methods: Sixteen players (8 male, 8 female) with at least 7 years competitive experience participated in a randomized crossover study. They underwent three experimental conditions: no nap (No-Nap), 25-min (N25), 45-min (N45). Physical was measured through counter-movement jumps (CMJ) agility tests, while function assessed using D2 attention test. Statistical analysis included repeated measures ANOVA examine differences between conditions gender-specific responses. Results: Significant improvements both physical were observed N25 N45 compared No-Nap condition (indicating effectiveness short enhancing performance). Males outperformed females most metrics, scored higher test (suggesting possible responses napping). The showed slightly better results terms quality subsequent (confirming that shorter may be more beneficial). Conclusions: Post-lunch naps, especially 25 or min, These findings suggest integrating into athletes’ training regimens can improve focus, potential benefits. Further research is needed explore long-term effects variations across other sports.

The Acute Effects of 25- Versus 60-Minute Naps on Agility and Vertical Jump Performance in Elite Youth Soccer Players: The Role of Individual Chronotype

Life, Journal Year: 2025, Volume and Issue: 15(3), P. 422 - 422

Published: March 7, 2025

Introduction: While napping is recognized as an effective strategy for mitigating insufficient sleep and enhancing athletic recovery, limited research exists on its effects football players’ anaerobic performance, particularly concerning chronotype variations. This study investigated the impact of strategic durations performance agility in players under age 19 (U19), considering individual chronotypes psychological factors. Methods: Sixteen young (age: 17.18 ± 1.04 years) participated this crossover randomized controlled study. Participants underwent three conditions: no nap (NoN), 25 min (N25), 60 (N60), with 48 h washout periods between sessions. Performance was assessed using Countermovement Jump Test (CMJ), Illinois Agility Test, Change-of-Direction Ball. Chronotype assessment, quality, mood states were evaluated Morningness-Eveningness Questionnaire, Pittsburgh Sleep Quality Index, Profile Mood States respectively. Results: The protocol demonstrated significant improvements compared to other conditions, However, differences observed CMJ parameters across conditions. variations showed correlations factors, evening-type participants displaying different responses interventions morning-type participants. Conclusions: a post-lunch did not affect it positively influenced soccer players. Chronotypic significantly impacted both associated These findings suggest that integrating strategies into training programs, while chronotypic variations, may present opportunities specific aspects performance. Further needed elucidate underlying physiological, psychological, cognitive mechanisms these effects.
