however, I will say that the coach should determine\u00a0<em>what\u00a0<\/em>the athlete should be stretching and setting the ground rules for how long each stretch should be held, sets, reps, etc, instead of just letting them do whatever they want.<\/p>\n<p>A recent study published in the\u00a0<em>Journal of Strength and Conditioning Research\u00a0<\/em>by Fariatti et al (2011) evaluated the response that stretching had on Heart Rate Variability (HRV) in subjects with low flexibility.<\/p>\n<p><em>Note:\u00a0<\/em>I have talked about HRV in a few previous blog posts &#8211;\u00a0<a title=\"Using Heart Rate Variability To Measure Stress: There\u2019s an app for that!\" href=\"https:\/\/optimumsportsperformance.com\/blog\/using-heart-rate-variability-to-measure-stress-theres-an-app-for-that\/\" target=\"_blank\">Using Heart Rate Variability to Measure Stress: There\u2019s an app for that!<\/a>\u00a0and\u00a0<a title=\"Massage, Stress and HRV\" href=\"https:\/\/optimumsportsperformance.com\/blog\/massage-stress-and-hrv\/\" target=\"_blank\">Massage, Stress, and HRV<\/a>.<\/p>\n<p><strong>What They Did And What They Found<\/strong><\/p>\n<p>The\u00a0authors took 10 male subjects, approximately 23yrs of age, who had at least 1yr of strength training background, and had low flexibility (classified in\u00a0percentiles 10-40 on the sit-and-reach test according to the ACSM standards).<\/p>\n<p>During the study the subjects performed three stretches \u2013 right hurdler stretch, left hurdler stretch, and butterfly stretch \u2013 each held for 30sec at maximum end range, with 30sec rest between sets, for 3 sets, and one minute rest between each exercise.\u00a0 The total session lasted approximately 10min.<\/p>\n<p>The heart rate of the subjects was recorded for 30min. before the stretch program, during the stretching program, and for 30min. after the stretching program.\u00a0 To evaluate HRV changes, the last 10min. of each testing period (pre, during, post) were used to for this measurement.<\/p>\n<p>The subjects had increased their\u00a0heart rate\u00a0during the stretching session; however,\u00a0<strong>their heart rate did decline during the recovery period to a value significantly lower than their pre-exercise heart rate.<\/strong><\/p>\n<p>The researchers also found that the 10min. stretching\u00a0sessionincreased post exercise vagal tone, as evident\u00a0by a decrease in\u00a0low frequency to high frequency power during the recovery period following its increase during the stretching session (although it was still higher than it was at rest, during the pre-stretching session).\u00a0\u00a0<strong>Thus parasympathetic activity improved (HRV improved).<\/strong>\u00a0 This paper was in agreement with a previous paper that the authors cited, showing increases in HRV following a 15min. stretching routine performed by athletes over a 28 day period.<\/p>\n<p>One of the unfortunate things was that the study did not include a control group.\u00a0 For example, what would the HRV and heart rate response been for a group of low-flexibility individuals who lied on a table for 70min. during the entire testing and stretching session period?\u00a0 Additionally, what would have been the results of the study if the subjects had been individuals with adequate flexibility?\u00a0 Would there have been the same changes in heart rate and HRV?\u00a0 What if the subjects were high level athletes?\u00a0 Of course these are all things that will hopefully be looked at in future studies; however, I think this information might be a good start in helping us formulate more ideas to assist athletes in recovering from hard training sessions or competition.<\/p>\n<p><strong>Practical Application<\/strong><\/p>\n<p>As stated earlier in this post, recovery modalities can be utilized following training (commonly a brief period after training or even later in the day, as a second session) or on the day following a hard training session.<\/p>\n<p>About 6 or 7 years ago, when I realized that I couldn\u2019t kill myself in the gym every single day, I purchased the book\u00a0<strong>Real Men Do Yoga: 21\u00a0star athletes reveal their secrets for strength, flexibility, and peak performance\u00a0<\/strong>by John Capouya.\u00a0 I figured it would be a good idea to supplement my training with some sort of flexibility regimen.\u00a0 Slowly, over the years, the book worked its way to the bottom of a large pile of other books, and I forgot about it, until I read this paper and decided to pull it out.\u00a0 However, one of the\u00a0limitations of yoga is that taking a large class at a gym\/fitness facility usually has some drawbacks.<\/p>\n<p>First, the stretches being performed are not specific to you and your needs.\u00a0 They are just a sequence that teacher tends to favor, so perhaps, specific limitations that you bring to the table may hinder your ability to perform some of these movements or potentially cause you injury.<\/p>\n<p>Second, it is hard to get help or instruction when you are in a large group like that; as the teacher is commonly in the front of the room and the first few rows of the class are dominated by the women who take the class 10 times a week and\u00a0can perform every pose perfectly.\u00a0 Those of us who are not as flexible or who lack competency in the poses tend to move towards the back of the room where we will be less embarrassed or feel like we are less\u00a0<em>in the way.<\/em><\/p>\n<p>Finally, the teacher dictates the flow of the class and there are many forms of yoga.\u00a0 If you are attempting to recover from hard training, it may be difficult to locate a class or teacher that understands those needs and the class may be more aggressive than what you really need.<\/p>\n<p><em>What to do?!?!<\/em><\/p>\n<p>I think the best thing you can do is find a coach\/trainer that can assess your needs, assess your training program, and prescribe some things that you can do to help improve your mobility and\u00a0in a sequence that is rather slow and controlled so that it can be performed on days in between hard training or later in the day following training to perhaps reap some of the benefits that the above paper is suggesting (improved parasympathetic state, decreased resting heart rate, etc).<\/p>\n<p>One of the things that the book\u00a0<strong>Real Men Do Yoga\u00a0<\/strong>has is various stretching schemes which flow from one stretch to the next,\u00a0which may be of value, and of course you can swap some of the stretches in these schemes that don\u2019t fit into your needs for stretches that do.\u00a0 When I look at some of these schemes, I am reminded of some of the mobility schemes that Gray Cook lays out in his book\u00a0<strong>Athletic Body In Balance.\u00a0\u00a0<\/strong>There\u00a0ar a lot of similarities between these two books with regard to the movement sequences.\u00a0 This is one of the reasons why I have often recommended to various yoga practitioners that they take the Functional Movement Screen course, to help drive their stretching routines for their clients.<\/p>\n<p><strong>Conclusion<\/strong><\/p>\n<p>Recovery is an important component of sports conditioning.\u00a0 Stretching routines may be one aspect that can aid an athlete in getting into a more relaxed\/parasympathetic state.<\/p>\n<p>Before just going out and stretching, try and find a training, therapist, or yoga practitioner who understands assessment and can individualize a mobility\/flexibility scheme to your needs.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Recovery is an important component of any good training program given the fact that if you can\u2019t recover from the training stress you won\u2019t be able to make any progress (in fact you will more than likely begin to slide backward).
