They will be able to identify the symptoms and their HRV and RHR figures will allow them to distinguish whether they are suffering from overreaching or overtraining. Athletes should take a reading immediately following a high intensity workout, and then again one hour after completion of the workout. Usually the RMSSD for the immediate reading will be in single figures. Recovery figures of the RMSSD will be specific to the individual, and they will be able to determine from a history of readings whether the recovery figure is within expected norms. The reading the following morning will indicate the degree of sleep recovery.\u00a0<\/p>\n<p><strong>Prevention strategies for overtraining are a good diet, full hydration, rest between training sessions and good sleep.\u00a0<\/strong><\/p>\n<p>RHR and recovery RMSSD patterns will indicate whether there is cause for concern, and whether more detailed diagnosis is necessary.<\/p>\n<p><strong>Call on the HRV Health team if you need any further guidance.<\/strong><\/p>\n<p><strong>Update:<\/strong><\/p>\n<p>HRV Health has introduced a new feature for users, providing them with advisories on their recovery status with suggestions that will help users to optimise their training.<\/p>\n<div class=\"speaker-mute footnotes_reference_container\"> <div class=\"footnote_container_prepare\"><p><span role=\"button\" tabindex=\"0\" class=\"footnote_reference_container_label pointer\" onclick=\"footnote_expand_collapse_reference_container_214_1();\">References<\/span><span role=\"button\" tabindex=\"0\" class=\"footnote_reference_container_collapse_button\" style=\"display: none;\" onclick=\"footnote_expand_collapse_reference_container_214_1();\">[<a id=\"footnote_reference_container_collapse_button_214_1\">+<\/a>]<\/span><\/p><\/div> <div id=\"footnote_references_container_214_1\" style=\"\"><table class=\"footnotes_table footnote-reference-container\"><caption class=\"accessibility\">References<\/caption> <tbody> \r\n\r\n<tr class=\"footnotes_plugin_reference_row\"> <th scope=\"row\" class=\"footnote_plugin_index_combi pointer\"  onclick=\"footnote_moveToAnchor_214_1('footnote_plugin_tooltip_214_1_1');\"><a id=\"footnote_plugin_reference_214_1_1\" class=\"footnote_backlink\"><span class=\"footnote_index_arrow\">&#8593;<\/span>1<\/a><\/th> <td class=\"footnote_plugin_text\"><a href=\"https:\/\/link.springer.com\/article\/10.1007\/s10286-016-0360-z\">Detailed heart rate variability analysis in athletes<\/a><\/td><\/tr>\r\n\r\n<tr class=\"footnotes_plugin_reference_row\"> <th scope=\"row\" class=\"footnote_plugin_index_combi\" ><a id=\"footnote_plugin_reference_214_1_2\" class=\"footnote_backlink\" onclick=\"footnote_moveToAnchor_214_1('footnote_plugin_tooltip_214_1_2');\"><span class=\"footnote_index_arrow\">&#8593;<\/span>2,<\/a> <a id=\"footnote_plugin_reference_214_1_5\" class=\"footnote_backlink\" onclick=\"footnote_moveToAnchor_214_1('footnote_plugin_tooltip_214_1_5');\"><span class=\"footnote_index_arrow\">&#8593;<\/span>5<\/a><\/th> <td class=\"footnote_plugin_text\"><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/9631215\/\">Fatigue and underperformance in athletes: the overtraining syndrome<\/a><\/td><\/tr>\r\n\r\n<tr class=\"footnotes_plugin_reference_row\"> <th scope=\"row\" class=\"footnote_plugin_index_combi pointer\"  onclick=\"footnote_moveToAnchor_214_1('footnote_plugin_tooltip_214_1_3');\"><a id=\"footnote_plugin_reference_214_1_3\" class=\"footnote_backlink\"><span class=\"footnote_index_arrow\">&#8593;<\/span>3<\/a><\/th> <td class=\"footnote_plugin_text\"><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/9232559\/\">Modeling training and overtraining<\/a><\/td><\/tr>\r\n\r\n<tr class=\"footnotes_plugin_reference_row\"> <th scope=\"row\" class=\"footnote_plugin_index_combi pointer\"  onclick=\"footnote_moveToAnchor_214_1('footnote_plugin_tooltip_214_1_4');\"><a id=\"footnote_plugin_reference_214_1_4\" class=\"footnote_backlink\"><span class=\"footnote_index_arrow\">&#8593;<\/span>4<\/a><\/th> <td class=\"footnote_plugin_text\"><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/9232560\/\">The &#8216;worn-out athlete&#8217;: a clinical approach to chronic fatigue in athletes<\/a><\/td><\/tr>\r\n\r\n <\/tbody> <\/table> <\/div><\/div><script type=\"text\/javascript\"> function footnote_expand_reference_container_214_1() { jQuery('#footnote_references_container_214_1').show();
