• Are You Addicted To Your Fitness Tracker?

    Are you addicted to your fitness tracker? Sundried

    Fitness tracking started with written logs and spreadsheets in the 1980s but has now evolved into an industry that’s set to be worth $19 billion by 2018. Smart watches can track your steps, sleep, heart rate, and more, and we're becoming more reliant on them than ever. But are we becoming addicted to their feedback? And is that necessarily a bad thing?

    Benefits Of Using An Activity Tracker

    Fail to plan, plan to fail

    Fitness trackers help you to put a plan into place. They give your walk meaning and they help to create a routine which adjusts to fit your daily activity. Fitness trackers give you a fantastic insight into where your fitness is at and where it should be going. They can also provide motivation; if you're 2,000 steps away from your goal, you're more likely to go for a walk around the block to make up the steps.

    Accountability

    Fitness trackers give your workout accountability. Every activity will be there for you to view via the app and some trackers even share directly with your social media, so everyone knows what you’ve been getting up to. Fitness trackers also mean you can’t cheat yourself and will give you in black and white exactly what results you got from your last training session.

    Motivation

    The leading benefit of tracking your steps, distance, sleep, calories and heart rate amongst other measures is to keep you motivated to do more. Whether it’s to earn a Fitbit gold star or score higher than your friends on Nike Plus, fitness trackers enable that extra incentive that gets you moving more, eating healthier, and going to bed earlier. Putting numerative data on your movement means you’re able to see progress and adjust your activities accordingly.

    Competitiveness

    Those with a competitive streak love a fitness tracker because even if they’re not competing against their friends, they can compete against themselves. Quantifying your fitness makes it easy to monitor progress and up your game when needed. The better you are, the more bragging rights you earn and you’ll have the data to back up your brag.

    Activity Trackers In Numbers

    • Fitbit users walk 43% more than non-Fitbit users.
    • 13.5 million health and fitness trackers (HFTs) were sold in 2014 and the numbers are shooting up every year.
    • Currently, around one in seven (14%) Brits own any wearable technology.
    • Fitbit (the largest wearable company) has 9.5 million active users.
    • Employees equipped with wearable technology reported an 8.5% increase in productivity and a 3.5% increase in job satisfaction.
    • Most people who use wearable tech are young; 48% are between 18 and 34.
    • Growth in the wearables market is expected to increase 35% by 2019.

    Are We Addicted?

    The problem with fitness trackers comes with the obsession over numbers which aren’t necessarily 100% accurate, which can then rather ironically lead to some unhealthy habits. Is it good for your mental health to be obsessing over calories and steps every waking hour?

    It's possible that obsessing over fitness statistics can lead to overtraining, and it's always more important to listen to your body than your tracker. Having it as a support system is great, but never forget that it's all just for fun and is nothing to lose sleep over.

  • Why Is Sleep Important For Recovery?

    Training Recovery Sleep Tracking

    We all know that getting at least 8 hours of sleep a night is important for being healthy, but why? And how does it affect our training?

    How important is sleep to building muscle?

    Not only does your body go through different stages of recovery as you sleep, how your body rested affects how you perform and eat the next day.

    Research by the Annals of Internal Medicine discovered that having less than seven hours of sleep per night can reduce and undo the benefits of dieting in order to lose weight in combination with an exercise regime. In the study, participants were put on different sleep schedules. When their sleep was cut back the amount of fat lost was cut in half, they felt significantly hungrier, were less satisfied after meals and lacked the energy to complete their exercise regime. Overall, their fat loss was reduced by 55% after inadequate rest.

    Another study on sleep monitored Stanford University players for the varsity basketball team. Researchers asked the players to increase their sleep time to roughly 10 hours per night, whereas they were used to sleeping for 6-9 hours. After they had slept more, the players had faster sprint times, their shooting accuracy improved, their free-throw percentage increased by 9% and three-point-field-goal percentage by 9.2%.

    The American Journal of Clinical Nutrition found that poor sleep can increase the levels of our stress hormone cortisol. This increase in cortisol will impact the body's ability to repair damaged muscle tissue, increase weight gain and elevate blood pressure.

    Sleep deprivation has also been seen to decrease production of glycogen and carbohydrates that are stored for energy use during physical activity. In short, less sleep increases the possibility of fatigue, low energy, and poor focus at game time. It may also slow recovery post-game.

    A recent study found that going for 18–20 hours without sleep had the same negative impact on performance as a blood alcohol level of 0.1 (0.08 is considered legally drunk in the US).

    What is recovery in training?

    Whilst we are sleeping our bodies release hormones which are essential for fitness recovery. The series of events that occurs once we shut our eyes is divided into 4 distinct categories.

    Sleep Stage 1:

    The first stage of sleep is characterised by drowsiness, slowing brain activity and shutting your eyes. This stage of sleep is the most easily disrupted. When it comes to muscles, at this stage they are still quite active and the eyes will roll around, often opening and closing. At this stage breathing becomes more regular and heart rate begins to slow, sudden jerks are common in this phase as sleeping takes over waking.

    Sleep Stage 2:

    Stage two typically constitutes 45-50% of sleep for adults. During this stage muscle activity decreases along with the consciousness of the outside world.

    Sleep Stage 3:

    Stage 3 sleep is the deepest stage of sleep your body enters. Your brain is resting with very little activity, so the blood supply available to your muscles increases, delivering extra amounts of oxygen and nutrients which facilitate their healing and growth. Your pituitary gland also releases a shot of growth hormone which stimulates tissue growth and muscle repair. Muscles and tissues are rejuvenated and new cells are regenerated during this phase of sleep.

    REM Sleep:

    REM sleep is the phase of sleep which is characterised by rapid eye movements. This phase of sleep is where the brain is most awake, but the rest of the body becomes almost paralysed. This is thought to be a built in measure to protect us from hurting ourselves during vivid dreams, as this is the phase of sleep where most dreams and or nightmares take place.

    Our sleeping pattern isn’t chronological and we may go through these cycles multiple times, however when it comes to recovery, we can see that stage 3 is our most valuable sleep stage.

    How many hours of sleep does an athlete need?

    Most people need about 6-8 hours of sleep per night, but when you’re training this can be significantly more. Just as athletes in training typically need to consume more calories, athletes in training typically need an extra hour of sleep, if not more.

    What happens to recovery if we don't get enough sleep:

    • Chronic sleep loss can result in a 30 - 40% reduction in metabolism.
    • Sleep loss causes an 11% reduction in time to exhaustion.
    • 2 days of sleep restriction can lead to 3 times the increases in lapses of attention and slowed reactions.
    • 1 rep max bench press is reduced by 20 lbs after 4 days of disturbed sleep.

    * According to research conducted by Zeo sleep manager.

    Roger Federer (Tennis)

    11-12 Hours

    Lindsey Vonn (Ski)

    9 Hours

    Usian Bolt (Sprinter)

    8 - 10 Hours

    Sarah Hughes (Skater)

    8 Hours

    Lebron James (Basketball)

    12 Hours

    Venus Williams (Tennis)

    8 - 9 Hours

    Tiger Woods (Golf)

    4 - 5 Hours

    Rafael Nadal (Tennis)

    8 - 9 Hours

    Maria Sharapova (Tennis)

    8 - 10 Hours

    Michelle Wie (Golf)

    10 - 12 Hours

    Steve Nash (Basketball)

    10 Hours


    These athletes clearly recognise the benefits of a good night's sleep on their performance, with Tiger Woods being our very own anomaly.

    What are the effects of lack of sleep?

    Not only will lack of sleep put your recovery under threat, it can have considerable effects on your health. Research has found:

    • Going to bed too late doubles the risk of breast cancer.
    • The risk of heart disease is increased by 100% if you get less than 7 hours sleep per night.
    • If you are sleep deprived you are 20% more likely to die in the next 20 years.

    How can I improve my recovery with sleep?

    1. Increase your magnesium intake. Magnesium, found in foods such as halibut, cereal, mixed nuts, soybeans and spinach will help to improve poor sleep.
    2. Eat a diet which combats inflammation. Eating a diet rich in colours will help to combat inflammation, which can lead to a restless night's sleep. Turmeric spice is a great aid for this.
    3. Take naps. If you struggle to sleep at night, napping throughout the day could be the answer to aid your recovery.
    4. Cut out stimulants at least 5 hours before you try to sleep. Caffeine can keep you awake at night or give you a restless night's sleep. Caffeine is a known central nervous system stimulant that takes 45 minutes to be completely absorbed by the body, and it takes approximately three to four hours to be completely eliminated and in some people, this could be even longer. Even if you're one of those types of people who can drink coffee and go right to sleep, it may still interfere with the quality of your sleep.
    5. If you still struggle to sleep after a tough training session, get checked with your GP for sleep apnea.
