Thereafter, we performed a crossover trial (ClinicalTrials.gov: NCT04197375) assessing the efficacy of head-neck precooling for mitigating the heat-induced psychophysical and performance impacts on junior athletes during tennis match play.<\/p>\n<p>Methods: ITF junior tournament information was collected. We identified meteorological data from nearby (13.6 [20.3] km) weather stations for 3056 (76%) tournaments.\u00a0Results: Overall, 30.1% of tournaments were held in hot (25\u00b0C-30\u00b0C wet-bulb globe temperature [WBGT]; 25.9%), very hot (30\u00b0C-35\u00b0C WBGT; 4.1%), or extremely hot (&gt;35\u00b0C WBGT; 0.1%) conditions. Thereafter, 8 acclimatized male junior tennis athletes (age = 16.0 [0.9] y; height = 1.82 [0.04] m; weight = 71.3 [11.1] kg) were evaluated during 2 matches: one with head-neck precooling (27.7\u00b0C [2.2\u00b0C] WBGT) and one without (27.9\u00b0C [1.8\u00b0C] WBGT).<\/p>\n<p>Head-neck precooling reduced athletes\u2019 core temperature from 36.9\u00b0C (0.2\u00b0C) to 36.4\u00b0C (0.2\u00b0C) (P = .001; d = 2.4), an effect reduced by warm-up. Head-neck precooling reduced skin temperature (by 0.3\u00b0C [1.3\u00b0C]) for the majority of the match and led to improved (P &lt; .05) perceived exertion (by 13%), thermal comfort (by 14%), and thermal sensation (by 15%). Muscle temperature, heart rate, body weight, and urine specific gravity remained unaffected (P \u2265 .05; d &lt; 0.2). Small or moderate improvements were observed in most performance parameters assessed (d = 0.20-0.79).<\/p>\n<p>Conclusions: Thirty percent of the last decade\u2019s ITF junior tournaments were held in hot, very hot, or extremely hot conditions (25\u00b0C-36\u00b0C WBGT). In such conditions, head-neck precooling may somewhat lessen the physiological and perceptual heat strain and lead to small to moderate improvements in the match-play performance of adolescent athletes.<\/p>\n<p><span style=\"color: #000000;\"><strong>Full Text Link: <\/strong><\/span><\/p>\n<p><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/34021093\/\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/pubmed.ncbi.nlm.nih.gov\/34021093\/<\/a><\/p>\n<p><img decoding=\"async\" class=\"alignnone wp-image-8302 size-full\" src=\"https:\/\/www.famelab.gr\/wp-content\/uploads\/2021\/11\/Line.png\" alt=\"\" width=\"1316\" height=\"1\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Misailidi M, Mantzios K, Papakonstantinou C, Ioannou LG, Flouris AD.
