    Hey,

    I play football and as we coming near the end of the season and the brighter evening our league in the infinite wisdom have been scheduling 3 games a week for us lately - Sat/Mon/Wed... its tough going on the aul legs and my hamstrings are screaming for a rest.

    I have another game tomorrow and just wondering if anybody has any experience with ice baths. Would it be beneficial to have one this evening in for my legs to help them recover a bit better before tomorrow?

    Or is a good hot bath with Epsom Salts/Radox just as good?

    Also does it have to be ice cold to be beneficial or would a c bath run from the cold tap do the job???

    Thanks

    as far as I know the optimum time to use an ice bath is directly after you've finished exercise.
    From ice bath, to hot shower and back to ice bath 3 times is what we used to do for the football.
    i was skeptical and didnt bother first few weeks but tried in one night and couldnt believe the difference the next day.

    Let me guess...UCFL??? We're in Div 1, same both. Our lads are dropping with injuries left right and centre.

    Absolutely disgraceful on the league's behalf.

    AUL Actually... we are 4th in the league (best hope is for 2nd really) and still in two cups! Q-Final tomorrow - just praying it doesn't go to extra time!!!

    I think the British Journal of Sports Medicine did a study where it showed that ice baths increase recovery time.

    Can only speak from personal experience, but I've found them hugely beneficial any times I've used them.

    A contrast shower might be a handier and possibly more effective method, you turn the water on hot as high as you can handle for a minute or so then switch to cold for min, repeat a few times. You can direct it onto the muscles most affected with the shower head.

    This is what i was going to suggest.

    I find them very handy after a deadlift or squat session actually, to just turn the hose on my lower back or quads for a few mins switching between hot and cold, gets the blood moving.


  • Registered Users, Registered Users 2 Posts: 634 ✭✭✭Jonny303


    i really recommend them. ive found the bath/shower far better than just a hot/cold shower but its not always the most practical. i started now after a good deads/squat session. using a (cleaned) wheelie bin and just chnge the water every so often in it


  • Closed Accounts Posts: 8,722 ✭✭✭nice_guy80


    crucial is a good warm down after the game - dynamic stretching

    sit in ice bath for at least 30 secs
    hot shower for 30 secs
    repeat three times. (plunge pools are great for this - also can be done at home with loads of ice and cold water...)
    should be done within 20 minutes of finishing exercise.

    then take a recovery shake to help get food to the muscles quickly. followed by a good dinner and lots of sleep.

    An interesting test would be doing a load of squats and just treating one leg, to see if there is a difference in DOMS.

    Rather you than me lol, sounds like it would make the dom'd up leg feel that much worse. I did it on my back a little earlier and the muscles are much more relaxed its nice to have an easy fix like that to use.

    Got asked a question about this so thought I would answer it here rather than just by PM.

    In short with regard ice baths.

    The entire vote is not in but on early returns it appears that:

    cold water immersion is best and that 10-15mins of immersion is the sweet spot with regard timing.

    cold water alone is significantly better than contrast immersion.

    cold water and contrast immersion beats doing nothing by a country mile

    these conclusions are made with regard performance in power and sprint repeatability.

    Yes...that would help...post exercise is best...as soon as is practicable.
    Or is a good hot bath with Epsom Salts/Radox just as good?
    A hot bath would actually appear to be contra indicated at this stage.
    Also does it have to be ice cold to be beneficial or would a c bath run from the cold tap do the job???

    Thanks
    Irish cold water in winter I would imagine would be plenty cold enough.

    Correct.
    From ice bath, to hot shower and back to ice bath 3 times is what we used to do for the football.
    I know from experience that 'feels' better and it is what I've done myself previously but this is no longer considered best practice in professional sport.
    i was skeptical and didnt bother first few weeks but tried in one night and couldnt believe the difference the next day.
    I've also always been sceptical but there is starting to be more and more valid data to back it up.


  • Closed Accounts Posts: 2,045 ✭✭✭Will Heffernan

    There has been a few studies like that. The studies that have the most data 'like' that were designed to be scientifically rigid but not so easily applied practically.

    That is...attempting to illicit DOMs via heavy eccentric loading on what is basically a leg extension machine and then applying ice packs to the area and then retesting 48hrs later.

    More of the recent data has been collected 'in the field' or in some cases actually 'on the field' in pro sport...as in studies that have been conducted during actual training cycles in professional sport.

    That's pretty much exactly what I used to do and advise.

    The current research would tend to indicate that it isn't very effective.

    It appears getting no respite is actually the answer...stay immersed for 10-15 mins is what the literature is pointing towards.
    should be done within 20 minutes of finishing exercise.
    That's also what the literature is pointing towards....that is...the sooner the better.

    correct
    but who has 15 minutes to sit in an ice bath or plunge pool, especially when other people want to use it.

    I've actually increased my stints in the ice bath to 2 minutes, if I can stick it.

    Ice baths/packs do not help your muscles recover from training - it's a myth. For your body to heal anything there needs to be blood flowing to the area. Applying cold things to a muscle draws all the blood away from it and, in my experience, only makes it stiffer. There's just no logical/scientific base for using ice for anything other than temporary pain relief. Most studies being done now support this, and this one indicates that icing even slows down the recovery process http://journals.lww.com/nsca-jscr/Abstract/publishahead/Topical_Cooling__Icing__Delays_Recovery_from.98090.aspx

    Heat is best because it moves blood into the area. Massage/foam rolling is good too. One other thing to note is that the likes of Deep Heat also don't work. It open the capillaries close to the skin, which also draws blood away from the muscle, and gives the burning sensation on the surface of the skin.

    Ummmm actually....it's not. Your statement is completely unsupported by current data and research. For a start putting together the topical application of ice packs and immersion in ice baths together is like putting the 100m and 10,000m together for the purposes of research as they are both run on a track.
    For your body to heal anything there needs to be blood flowing to the area.
    This is completely false and displays no understanding of human physiology and healing at all.
    Applying cold things to a muscle draws all the blood away from it and, in my experience, only makes it stiffer.
    This statement is fine...you should of added this disclosure to the rest of your statements.
    There's just no logical/scientific base for using ice for anything other than pain relief.
    This is a complete fallacy.

    I don't even know where to begin. The only reason I am even bothering to reply is because the statements you are making are just plain dangerous and the thought that some people might naively follow your advice actually scares me.

    Show me ANY evidence at all where the application of heat is indicated in improving recovery post exercise.

    This statement I can agree with. As in this study doesn't show much in the way of variability between cooling modalities.

    BUT

    Have you actually read the study? Were the subjects trained or untrained? Did you see the intensity of the testing protocol?

    This is one study and you have to ensure that you look at studies as a whole rather than cherry picking them in an attempt to support your argument.

    For example....If I made the statement 'The effect of anabolic steroids on muscle hypertrophy and growth were found to be purely psychological' and then posted the link to one scientific abstract that supported my statement would you believe me or would you find that a little disingenuous?
    I think its a personal thing, some people love them and they work, some hate them and they dont work
    This I disagree with but as you've stated that it is your personal opinion rather than in anyway backed up by huge amounts of data I suppose it is fine.

    I think based on the research currently available that your opinion is incorrect and that it is more like...some people love them and they work, some hate them and they still work.

    That is not a pretty good video on the subject. It's an advertisement.

    You are not helping your argument...the fact that he doesn't actually understand exercise physiology in not really a great start either.

    What about if I stick up some videos of Chuck Norris and his Total Gym discussing it's superiority over traditional resistance/weight training?

    What about if I stick up some videos of people and their vibro plates discussing its superiority over traditional resistance/weight training?

    I am talking about the preponderance of actual scientific data not some pseudo scientific advertisement by some dudes selling equipment.

    I actually find that video offensive in it's stupidity....I feel noticeably dumber after watching it.

    Effects of Water Immersion on Post-training Recovery in Australian Footballers.

    Institute of Sport, Exercise and Active Living, School of Sport and Exercise Science, Victoria University, Melbourne, Australia.
    Abstract
    PURPOSE:
    We investigated the efficacy of a single exposure to 14-min of cold water immersion (COLD) and contrast water therapy (CWT) on post-training recovery in Australian football (AF).
    METHOD:
    Fourteen AF players participated in three weeks of standardised training. Following week 1 training, all players completed a passive recovery (PAS). During week 2, COLD or CWT was randomly assigned. Players undertook the opposing intervention in week 3. Repeat-sprint ability (6 x 20-m), countermovement and squat jumps, perceived muscle soreness and fatigue were measured pre-training and over 48 h post-training.
    RESULTS:
    Immediately post-training, groups exhibited similar performance and psychometric declines. At 24 h, repeat-sprint time had deteriorated by 4.1% for PAS and 1.0% for CWT but was fully restored by COLD (0.0%). At 24 and 48h, both COLD and CWT attenuated changes in mean muscle soreness, with COLD (0.6±0.6 and 0.0±0.4) more effective than CWT (1.9±0.7 and 1.0±0.7) and PAS having minimal effect (5.5±0.6 and 4.0±0.5). Similarly, after 24 and 48 h, COLD and CWT both effectively reduced changes in perceived fatigue, with COLD (0.6±0.6 and 0.0±0.6) being more successful than CWT (0.8±0.6 and 0.7±0.6) and PAS having the smallest effect (2.2±0.8 and 2.4±0.6).
    CONCLUSIONS:
    Australian football training can result in prolonged physical and psychometric deficits persisting for up to 48 h. For restoring physical performance and psychometric measures, COLD was more effective than CWT, with PAS being the least effective. Based on these results we recommend 14-min of COLD be used following AF training.

    Consecutive days of cold water immersion: effects on cycling performance and heart rate variability.
    Stanley J, Peake JM, Buchheit M.
    Source
    Centre of Excellence for Applied Sport Science Research, Queensland Academy of Sport, Brisbane, Australia, j.stanley@uq.edu.au.
    Abstract
    We investigated performance and heart rate (HR) variability (HRV) over consecutive days of cycling with post-exercise cold water immersion (CWI) or passive recovery (PAS). In a crossover design, 11 cyclists completed two separate 3-day training blocks (120 min cycling per day, 66 maximal sprints, 9 min time trialling [TT]), followed by 2 days of recovery-based training. The cyclists recovered from each training session by standing in cold water (10 °C) or at room temperature (27 °C) for 5 min. Mean power for sprints, total TT work and HR were assessed during each session. Resting vagal-HRV (natural logarithm of square-root of mean squared differences of successive R-R intervals; ln rMSSD) was assessed after exercise, after the recovery intervention, during sleep and upon waking. CWI allowed better maintenance of mean sprint power (between-trial difference [90 % confidence limits] +12.4 % [5.9; 18.9]), cadence (+2.0 % [0.6; 3.5]), and mean HR during exercise (+1.6 % [0.0; 3.2]) compared with PAS. ln rMSSD immediately following CWI was higher (+144 % [92; 211]) compared with PAS. There was no difference between the trials in TT performance (-0.2 % [-3.5; 3.0]) or waking ln rMSSD (-1.2 % [-5.9; 3.4]). CWI helps to maintain sprint performance during consecutive days of training, whereas its effects on vagal-HRV vary over time and depend on prior exercise intensity.

    Abstract
    The aim of the present study was to investigate the potential benefits of cold water immersion (CWI) and active recovery (AR) on blood lactate concentration ([Lac]) and heart rate variability (HRV) indices following high-intensity exercise. 20 male subjects were recruited. On the first visit, an incremental test was performed to determine maximal oxygen consumption and the associated speed (MAS). The remaining 3 visits for the performance of constant velocity exhaustive tests at MAS and different recovery methods (6 min) were separated by 7-day intervals [randomized: CWI, AR or passive recovery (PR)]. The CWI and AR lowered [Lac] (p<0.05) at 11, 13 and 15 min after exercise cessation in comparison to PR. There was a 'time' and 'recovery mode' interaction for 2 HRV indices: standard deviation of normal R-R intervals (SDNN) (partial eta squared=0.114) and natural log of low-frequency power density (lnLF) (partial eta squared=0.090). CWI presented significantly higher SDNN compared to PR at 15 min of recovery (p<0.05). In addition, greater SDNN values were found in CWI vs. AR during the application of recovery interventions, and at 30 and 75 min post-exercise (p<0.05 for all differences). The lnLF during the recovery interventions and at 75 min post-exercise was greater using CWI compared with AR (p<0.05). For square root of the mean of the sum of the squares of differences between adjacent R-R intervals (RMSSD) and natural log of high-frequency power density (lnHF), a moderate effect size was found between CWI and PR during the recovery interventions and at 15 min post-exercise. Our findings show that AR and CWI offer benefits regarding the removal of [Lac] following high-intensity exercise. While limited, CWI results in some improvement in post-exercise cardiac autonomic regulation compared to AR and PR. Further, AR is not recommended if the aim is to accelerate the parasympathetic reactivation.

    Effects of cold-water immersion and contrast-water therapy after training in young soccer players.
    De Nardi M, La Torre A, Barassi A, Ricci C, Banfi G.

    University of Milan, Milan, Italy - massimodenardi@alice.it.
    Abstract
    AIM:

    Recent studies have investigated the importance of recovery strategies after training session, including hydrotherapy and cryotherapy. However, only a few studies have focused on cold-water immersion (CWI) treatments in team sport disciplines. The present study investigates the effects of CWI and contrast-water therapy (CWT) on the performance of young male soccer players during a week of training.
    METHODS:

    Eighteen young soccer players participated in the present study (age 15.5±1.0 years, weight 61.8±3.0 Kg, height 175.5±4.0 cm and training experience 8.1±1.0 years). They were involved in a four-day study with recovery using CWI or with CWT after each training session by using performance tests and small-sided games. We measured uric acid concentration, leukocytes, haemoglobin, reticulocytes and creatine kinase changes in the blood, axillary temperature, rating of perceived exertion after a training session, heart rate during exercise, performance tests (counter movement jump, repeated sprint ability and 5' shuttle run).
    RESULTS:

    No significant difference were reported between groups when different physiological tests were used; CWI and CWT did not negatively influence the performances of the athletes. The principal effect of CWI was a reduced perception of fatigue after the training session. The use of active recovery protocols based on cold water or cold/thermoneutral water did not induce modifications of inflammatory and haematological markers in young soccer players.
    CONCLUSION:

    The beneficial effect of a reduced perception of fatigue can improve training and competitions in young soccer players.

    Abstract
    OBJECTIVE:

    : This study was designed to analyze changes in muscle response after cold-water immersion.
    DESIGN:

    : The vastus lateralis of the dominant leg was analyzed in 12 professional soccer players from the Spanish 2nd Division B using tensiomyography, before and after four cold-water immersions at 4°C lasting 4 mins each. Core temperature, skin temperature, and heart rate were monitored.
    RESULTS:

    : A significant interaction (P ≤ 0.05) was found in muscle deformation between control conditions (5.12 ± 2.27 mm) and (1) immersion 3 (3.64 ± 2.27 mm) and (2) immersion 4 (3.38 ± 1.34 mm). A steady decrease was also observed in response velocity (immersion 1, -7.3%; immersion 2, -25.9%; immersion 3, -30.0%; immersion 4, -36.6%) and contraction velocity (immersion 1, -11.5%; immersion 2, -22.1%; immersion 3, -35.0%; immersion 4, -41.9%), with statistically significant differences (P ≤ 0.05) in relation to the reference values commencing with the third immersion. No significant differences were found between control conditions in subsequent exposures to cold water for the values of response time and contraction time. Sustained time and reaction time showed an increase during repeated exposures and with longer exposure time, although the increase was not statistically significant.
    CONCLUSIONS:

    : This study shows that repeated cold-water immersions (4 × 4 mins at 4°C) cause considerable alterations to muscle behavior. These alterations significantly affect the state of muscles and their response capacity, particularly in relation to muscle stiffness and muscle contraction velocity.

    Abstract

    In order to investigate the effectiveness of different techniques of water immersion recovery on maximal strength, power and the post-exercise inflammatory response in elite athletes, 41 highly trained (Football, Rugby, Volleyball) male subjects (age = 21.5 ± 4.6 years, mass = 73.1 ± 9.7 kg and height = 176.7 ± 9.7 cm) performed 20 min of exhaustive, intermittent exercise followed by a 15 min recovery intervention. The recovery intervention consisted of different water immersion techniques, including: temperate water immersion (36°C; TWI), cold water immersion (10°C; CWI), contrast water temperature (10-42°C; CWT) and a passive recovery (PAS). Performances during a maximal 30-s rowing test (P(30 s)), a maximal vertical counter-movement jump (CMJ) and a maximal isometric voluntary contraction (MVC) of the knee extensor muscles were measured at rest (Pre-exercise), immediately after the exercise (Post-exercise), 1 h after (Post 1 h) and 24 h later (Post 24 h). Leukocyte profile and venous blood markers of muscle damage (creatine kinase (CK) and lactate dehydrogenase (LDH)) were also measured Pre-exercise, Post 1 h and Post 24 h. A significant time effect was observed to indicate a reduction in performance (Pre-exercise vs. Post-exercise) following the exercise bout in all conditions (P < 0.05). Indeed, at 1 h post exercise, a significant improvement in MVC and P(30 s) was respectively observed in the CWI and CWT groups compared to pre-exercise. Further, for the CWI group, this result was associated with a comparative blunting of the rise in total number of leucocytes at 1 h post and of plasma concentration of CK at 24 h post. The results indicate that the practice of cold water immersion and contrast water therapy are more effective immersion modalities to promote a faster acute recovery of maximal anaerobic performances (MVC and 30″ all-out respectively) after an intermittent exhaustive exercise. These results may be explained by the suppression of plasma concentrations of markers of inflammation and damage, suggesting reduced passive leakage from disrupted skeletal muscle, which may result in the increase in force production during ensuing bouts of exercise.

    ....I've stopped here only because I am bored now.

    I've actually got these studies at home and unlike you I've read them.
