Furthermore, studies employing an intermittent fasting model for an extended Time-restircted reported an enhanced neuromuscular performance in athletes tean9 — Studies that previously investigated the Timd-restricted of Ramadan fasting Time-rsetricted performance shared significant design and exercising protocol issues in common Much of the available information on this topic has been collected from sedentary subjects or low-level competitors.

Such design issues can be remedied by recruiting non-Muslim athletes and having them fast, or by recruiting Muslim athletes and having them only fast for a few days, which does not resemble fasting for the entire month of Ramadan.

Additionally, to our knowledge, the impact of fasting on elite distance runners has not been investigated. The purpose of the current study is to investigate the effect of fasting during Ramadan i. Moreover, the authors hypothesized that distance running performance will be positively impacted by Ramadan fasting in elite distance runners.

Fifteen trained male distance runners who observed Ramadan participated in this study. Each participant reported to the human performance lab on two occasions pre-Ramadan and the last week of Ramadan.

In each visit, participants performed a graded exercise test on the treadmill 13 and their VO 2Heart Rate, time to exhaustion, RPE, and running speed were recorded.

Detailed anthropometrics, food records, sleep diary, and exercise logs were kept for the entire period of the study. All participants were active runners i.

After being informed of the procedures and potential risks involved in the investigation, an IRB-approved informed consent document was signed by each participant before the commencement of the study.

Participants were not instructed to alter their training duration, intensity, or frequency. The daily fasting period was equal to or exceeding 15 h. During the study, subjects consumed a meal before dawn at ~0, with testing sessions beginning 4—4.

The study was an observational design. All procedures were approved by the Hashemite University Institutional Review Board IRB number Before the study, participants were informed of the study's purpose, along with any associated risks and benefits. In accordance with the university institutional review board, and the Declaration of Helsinki, participants gave written informed consent and completed a health history questionnaire before the first test session.

All data was collected in the Human Performance Laboratory at Hashemite University. Participants completed three visits a familiarization visit and two testing visits on different days to undertake the study protocol as indicated below.

On visit one 2 weeks before Ramadananthropometric characteristics, health status, blood pressure and heart rate were assessed. Briefly, participants were familiarized with the testing protocol and tools.

Shortly after that, and following a 25—30 min resting period, the participants' blood pressure and resting heart rate HR rest measurements were conducted while seated, three readings were recorded, and their average was used to determine blood pressure and HR rest. On visit 2 3 days before Ramadan: Pre-Fasting and visit 33 end of the fourth week of Ramadan: End-Fasting preparations performed as described previously, and a Conconi 13 graded exercise test GXT to exhaustion began following a min rest and a 5-tomin warm-up period.

All time to exhaustion running trials were performed at approximately the same time of day between am and amto avoid discrepancies in results caused by testing time.

Oxygen consumption VO 2and carbon dioxide production VCO 2 were calculated breath by breath using a respiratory metabolic cart Quark PFT 2, COSMED. Rome, Italy. Heart rate and rate of perceived exertion RPE were obtained at the end of each stage 6—20, Borg scale chart.

Participants' heart rate was monitored throughout the entire period of each trial using a chest strap heart rate monitor Polar Electro, Oulu, Finland.

Time to exhaustion was considered the point at which participants triggered the emergency stop, the termination signal, or failed to stay within safe range of the safety harness. Time to exhaustion was considered valid if participants achieved at least two of the following criteria at the point of exercise termination:.

Plateau in VO 2 with increasing speed. Heart rate within 10 beats of the age predicted maximal heart rate. RPE value more than or equal to Body mass BM was measured with the use of a digital scale SECA, Hamburg, Germany to the nearest 0.

Height was determined with the use of a stadiometer SECA, Hamburg, Germany to the nearest 0. Measurements were compliant with the recommendations of the International Society for the Advancement of Kinanthropometry Guidelines. Body fat BFbody fat percentage, fat free mass FFMand total body water TBW were assessed with the use of four electrode bioelectrical impedance system InBody, Inbody Seoul, Korea.

Reliability and validity of the measurement system has been reported in the literature 6. Anthropometric measurements were obtained on each visit after subjects rested for a period of 30 min following their scheduled arrival time and before beginning the warmup.

Participants were instructed to keep daily food records and exercise logs. The food records provided full details about ingested food and fluids along with time of consumption, preparation method, meal type, and perceived mood. This software platform is routinely used in to validate other diet assessment tools Exercise logs contained details about type of event, training duration, training intensity, and provided information about frequency of training.

Exercise logs were analyzed using Sportlyzer Sportlyzer LLC. Exercise energy expenditure EEE was estimated using the Compendium of Physical Activities The Daily Sleep Diary Loughborough University, Loughborough, UK was used to evaluate each participant's subjective daily sleep score.

The sleep diary consisted of a brief eight item questionnaire, evaluating the sleep time and quality. This and similar instruments have been reported on in the literature During this study, sleep diary records were collected at two different times, one before at the start of the study visit and one during at the end of study visit.

The questionnaire was completed by each participant for the entire period of the study. The two sets of records were treated separately i. Sleep diaries that show bedtime and awake time and daytime napping during the weekdays and at weekends was obtained together with the total sleep duration in a h period i.

Comparison was administered for the difference in sleep duration before and during Ramadan. All data is presented as means ± standard deviation SD and was analyzed using SPSS version Once the assumption of normality was confirmed using the Shapiro-Wilk test, parametric tests were performed.

For anthropometric measures, sleep duration, and dietary variables, dependent sample t -test was used to detect significant differences between the two trials. For the RPE, VO2, and HR data, a two-way [Time pre and end of Ramadan x Speed] ANOVA with repeated measures was used.

When appropriate, paired t -test was used for pair-wise comparisons. Cohen's d effect size for pairwise tests and partial eta squared ηp 2 for repeated measures analyses were calculated to assess the magnitude of difference between the time points. Effect sizes were considered small at 0. Assessment of changes in body mass and body composition are presented in Table 1.

Latest news Medically reviewed by Daniel Bubnis, M.

Eating erratically and for too many hours daily can provoke chronic circadian disruption or a type of feeding 'jet-lag' which is believed by time-restricted eating proponents to be a driver of weight gain, poor sleep, increased risk of developing chronic disease and, in the end, a shorter life. Intermittent fasting is a dietary approach centered around eating and fasting for specific periods of time throughout the day or week.
Is Time-Restricted Eating Safe for Athletes? – Triathlete The power expressed by an athlete reflects the speed of the race or the ability to climb a greater slope at the same speed. It is also possible that during TRE protocol, subjects have slightly reduced their caloric intake, which might have increased the negative energy balance and reduced REE. We hypothesized that TRE would reduce inflammatory markers and fat mass without affecting physical performance. In this edition, we're sharing some science-backed longevity strategies to help increase your lifespan. Med Sci Sports Exer. Hatori M, Vollmers C, Zarrinpar A, et al.
Intermittent Fasting for Athletes: What Does the Research Say? In addition, it seems that TRE may exert a protective effect on some aspects of the immune system in the context of exercise training. Zauner C, Schneeweiss B, Kranz A, Madl C, Ratheiser K, Kramer L, et al. Though the authors concluded that longer-term studies are in great need to confirm these findings. Meng H, Zhu L, Kord-Varkaneh H, Santos HO, Tinsley GM, Fu P. However, in the last decade, IF has been used specifically to improve body composition and health status in both healthy and obese populations [ 2 , 3 , 4 , 5 ]. A fascinating concept, but likely one that has so many nuances which need to be sussed out through further research.
Time-Restricted Feeding and Aerobic Performance in Elite Runners: Ramadan Fasting as a Model

In a meta-analysis of randomized control trials published in the Journal of the Endocrine Society it was found that compared to control diets with no time constraints, time-restricted eating, defined in this report as 4 to 8 hours of unrestricted eating in 24 hours, resulted in improvements in total body weight and body composition fat mass to lean mass ratio in people who were overweight or obese.

However, the research review found there is not enough data to say that narrowing the eating window can bring about improvements in blood cholesterol LDL and HDL or triglyceride numbers. But a different review of previous research published in the journal Nutrients not only confirmed the benefits that time-restricted eating can have on body composition but suggests there indeed are certain cardiometabolic improvements with this style of eating including blood pressure, fasting blood sugar and blood triglycerides.

Though the authors concluded that longer-term studies are in great need to confirm these findings. There could be a few factors at play here as to why time-restricted eating can help the needle on the scale move to the left.

For most people, there are only so many calories that can be inhaled in a narrow feeding window. Many time-restricted eating protocols discourage feeding after dinner, which helps put the brakes on late-night snacking, a time when many of us eat out of stress or boredom instead of real hunger.

Scientists in Finland determined that compared to people whose calorie intake was proportionally lowest during the evening, those with proportionally highest calorie intake during the evening hours were more likely to be overweight, even if their chronotype suggested they were night types.

And not to be overlooked is that eating too much, too close to bedtime could disrupt sleeping patterns , and some research suggests that poor sleep can send people to seek out more calories from junk food.

RELATED: 3 Healthy Ways to Battle the Nighttime Sweet Tooth. There may also be some sort of positive impact on metabolism by noshing in better alignment with circadian rhythms, a concept that can be tricky to prove through research.

Some degree of fasting could set the stage for enhanced metabolic fuel switching, thus improving metabolic flexibility. Improvements in insulin sensitivity , blood sugar control and appetite that may result by eating less often could help in the battle of the bulge.

There is also the opportunity for people to finally learn what physiological hunger feels like, especially with narrower feeding windows, compared to psychological hunger where we are often eating simply because of factors like daily stress and anxiety.

Longevity experts believe a certain degree of daily fasting allows our bodies to undergo cellular natural selection. A time where old, damaged cells are replaced with newer, healthier ones in a process called autophagy.

Pathways involved in this cellular replacement are believed to be activated in the fasted state and suppressed in the fed state, the latter of which is what most Americans are in nearly all the time.

Feeding marathons robs us of the 12 to 16 hours we need to fully metabolize our last meal and lapse into autophagy mode. Autophagy has been shown to degrade damaged cellular components to re-use as an energy source during advanced stages of starvation in mice.

A fascinating concept, but likely one that has so many nuances which need to be sussed out through further research. Exactly how much fasting is required to increase autophagy in humans instead of laboratory animals is completely unknown. In the end, likely not quite the anti-aging miracle we all hope for.

There are certainly some good arguments to be made for taking fewer trips to the kitchen. In contrast to much of the general population, not all triathletes can benefit from a loss of body weight.

Already lean, or too-lean athletes may experience negative health and performance outcomes as a result of shedding more pounds. Nobody should consider a skin-and-bones cyclist post-Tour de France as the ideal physique. Time-restricted eating might be most useful during off-season training as a way to help athletes prevent any unwanted weight creep during periods of lesser calorie burn.

To date, there is little data to show that the initial weight loss experienced with time-restricted eating is lasting as long-term studies are lacking. So many diets fail to result in long-term adherence and lasting body composition improvements. We also desperately need to see studies conducted on female athletes and during various stages of the menstrual cycle.

Also, it is still up in the air what health benefits if any people with a healthy metabolic profile such as cholesterol and blood sugar numbers will glean from eating less often. Likely, we may never really know if time-restricted eating can extend lifespan because long-term studies like that are extremely challenging and cost-prohibitive.

But drawing conclusions from these studies and attempting to apply their findings to intermittent fasting is difficult. For a start, those who fast during Ramadan tend to consume far fewer calories than normal, which by itself will reduce performance, and often they suffer disturbances to their circadian rhythm caused by overnight eating.

A more recent review concluded that, as long as athletes maintain their total intake of calories and micronutrients and their typical sleep quality, they likely would not see any negative effects on performance. For most people most of the time, the timing of these factors is less important provided they consume enough food and fluid.

In fact, more recent research suggests that, for some athletes, periods of time with less—or even no—energy intake may help enhance performance. An important training adaptation for endurance athletes is the production of new mitochondria, called mitochondrial biogenesis.

When endurance athletes train, their bodies detect when energy stores are getting low, which releases several signaling factors including AMPK. These signaling factors, in turn, stimulate many of the positive adaptations to endurance exercise, including mitochondrial biogenesis.

As such, training in a low energy state is associated with enhanced training adaptations in some specific measures.

So periods of lower carbohydrate intake, which we might consider as a proxy although not a perfect one for intermittent fasting, may enhance or reduce training adaptations, depending on your overall training goal.

Similarly, not eating before a high-intensity exercise, such as sprints and resistance training, also will likely reduce training performance and, in turn, hamper competition performance. The only downside is when it comes to protein intake.

While by far and away the most important factor with protein is total daily intake, some evidence suggests that eating g every hours provides a small advantage regarding muscle protein synthesis, which could affect muscle recovery and growth. And though the impact of this may be small, it could make all the difference for elite athletes.

Some evidence suggests that regular intakes of protein spaced throughout the day are better than larger intakes consumed less often.

While the impact might be small, it could make the difference for elite athletes, and intermittent fasting would preclude this. Given that high-level athletes require much more nutrition than non-elite athletes and must spread out these nutrients across the day when they have multiple daily sessions, this time-restricted approach seems to be a sub-optimal option.

However for recreational athletes who train for shorter durations and with less intensity—and therefore have lower energy demands—intermittent fasting may be appropriate, especially for weight management.

In addition, blood counts, anabolic hormones i. free testosterone, IGF-1 and inflammatory markers i. IL-6, TNF-α were assessed. TRE could also be beneficial for reducing inflammation and may have a protective effect on some components of the immune system.

Overall, TRE could be considered as a component of a periodized nutrition plan in endurance athletes. Trial registration: This trial was retrospectively registered at clinicaltrials. The researchers also found some positives in blood markers of immune functioning, most notably less of a decline in leukocytes that can occur during bouts of high-intensity training.

Leukocytes are immune system white blood cells involved in helping us fend off infections. Other research results suggest that an intermittent fasting program in conjunction with resistance training can decrease fat mass while still maintaining muscle mass in resistance-trained males.

Already lean, or too-lean athletes may experience negative health and performance outcomes as a result of shedding more pounds.

Nobody should consider a skin-and-bones cyclist post-Tour de France as the ideal physique. Time-restricted eating might be most useful during off-season training as a way to help athletes prevent any unwanted weight creep during periods of lesser calorie burn. To date, there is little data to show that the initial weight loss experienced with time-restricted eating is lasting as long-term studies are lacking.

So many diets fail to result in long-term adherence and lasting body composition improvements. Sleep is crucial to athletic performance and recovery, as well as hormonal regulation. If fasting keeps you awake at night, consider shortening your fasting periods.

Keep eating like an athlete. While your eating schedule may change a bit when fasting, the macronutrient composition of the foods you eat before, during, and after a run should continue to support exercise performance and recovery. Elo Smart Protein is perfect for intermittent fasting runners of any age who want to maximize post-run recovery.

Each blend is hand-mixed just for you and is optimized to deliver the right amount of protein, and key amino acids after each workout to help you recover faster. Adding a carbohydrate boost branched cyclic dextrin or oat starch will help replenish energy stores as well.

Think of it as a supplement and protein powder in one scoop, uniquely designed for you and your recovery needs. Learn more about how it can enhance your recovery. If you are looking to lose weight and lean out without compromising performance, studies on athletes show intermittent fasting might be an effective strategy.

One randomized controlled trial found elite cyclists given an 8-hour feeding window lost weight, improved their body composition, and performed equally as well during a 4-week high-level training period.

The study also found time restrictive eating TRE may be beneficial for reducing inflammation and have a protective effect on some components of the immune system, which athletes may benefit from [ 7.

A number of studies have also been conducted on athletes who fast from sun up to sun down during Ramadan. While the Ramadan fasting schedule is the opposite of the typical TRF overnight fast, the research shows that athletes who maintain non-fasting energy and macronutrient intake, training load, body composition, and sleep length and quality typically do not experience any substantial performance losses while fasting during Ramadan [ 9.

Running in a fasted state will certainly hurt your short-term endurance, but can training while fasting boost performance when you compete with a full tank? While many athletes have tested this concept in recent years, there is little evidence that fasted endurance training improves endurance levels [ To date, there is very limited research on whether or not it is possible to gain muscle while intermittent fasting, largely because most of the research so far has focused on weight loss and metabolic health.

So far, the research evaluating the impact of intermittent fasting on body composition, and specifically muscle gain, in active individuals has shown mixed results.

One small, randomized trial found TRE did not hinder resistance training adaptations in resistance-trained females. These results suggest similar increases in muscle gains and muscular performance improvements can be achieved with different feeding regimens that contain similar energy and protein content during resistance training [ Another small study in healthy men looked at the impact of TRF on weight training.

In this study, the men, who had not previously weight trained, followed either a normal diet or a 4-hour time-restricted eating program four days per week. The time-restricted feeding group was able to maintain their lean body mass and increase their strength, but the normal diet group increased their strength and also gained five pounds of lean mass during the eight-week trial [ Fasting can make it difficult to get enough calories and protein that are needed to build muscle, and can also interfere with the timing and frequency of protein intake that promotes muscle building and repair.

Intermittent fasting has emerged as a popular dietary strategy and offers runners a unique approach to weight management and potential health benefits. While it can help improve body composition and metabolic health, fasting and running does require careful planning and may have lesser benefits for women.

When implemented carefully, intermittent fasting can complement a runner's lifestyle and performance without compromising overall health.

Intermittent fasting has broad benefits for many health conditions, including obesity, diabetes, heart disease, certain cancers, and neurologic disorders [ 2.

Research shows IF can improve metabolic health and blood sugar control by reducing insulin resistance, blood glucose, and fasting insulin levels [3, 5]. You can maintain your current running performance with IF as long as you prioritize your nutrition intake, training, and sleep [9].
