スポーツ業界では，自転車エルゴメーターやトレッドミル等を用いた運動試験において，マラソン競技の様な持続的運動が，鼻呼吸障害により運動能力へ影響を及ぼすと報告されている。しかし，サッカー等の競技時間の中で，休息時間となる低強度運動と，無酸素運動を伴う高強度運動を何度も繰り返す，間欠的高強度運動においては，鼻呼吸障害による運動能力への影響が明らかにされていない。今回我々は，鼻呼吸障害，いわゆる鼻閉状態を人為的に作成し，鼻呼吸障害が及ぼす持続的運動と間欠的高強度運動への影響を検討した。運動試験の手法としては，よりスポーツ現場に近い環境下での測定を考慮し，持続的運動に対しては20 mシャトルランを，間欠的高強度運動に対してはYo-Yo IRを選択し，走行回数や心拍数，アンケートによる調査を行った。結果は両運動において，正常状態に比し，強制的鼻閉状態で有意に走行回数の減少を認めた。同様に，アン...
Introduction: Inflammation in the brain is known as neuroinflammation and increases TNF-α (Tumor necrosis factor alpha) secretion and activates the TLR4 (Toll-like receptor 4) pathway. The aim of this study was to evaluate the effect of 4 weeks preconditioning with high intensity intermittent training (HIIT) and moderate intensity training (MICT) on TNF-α and TLR4 levels in male Wistar rats. M...
The purpose of this study was to assess, the effects of continuous and intermittent exercise training on lactate kinetic parameters and maximal aerobic speed (MAS) using field tests. Twenty-four male sport students were equally divided into continuous (CT) and intermittent (IT) physically trained groups. Another six participants acted as non-trained controls (CG). The trained participants pract...
OBJECTIVE To verify the acute effects of resistance exercise on post-exercise blood pressure in patients with intermittent claudication. METHODS Eight patients randomly underwent two experimental sessions: a session of resistance exercise (R: 6 exercises, 3 sets of 12, 10 and 8 reps with a perceived exertion of 11 to 13 on the 15-grade Borg scale) and a control session (C: resting on exercise...
Pyridoxal-phosphate-6-azophenyl-2'-4-disulfonate (PPADS), a purinergic 2 (P2) receptor antagonist, has been shown to attenuate the exercise pressor reflex in cats. In vitro, however, PPADS has been shown to block the production of prostaglandins, some of which play a role in evoking the exercise pressor reflex. Thus the possibility exists that PPADS blocks the exercise pressor reflex through a ...
Previously, the decline in glycemia in individuals with type 1 diabetes has been shown to be less with intermittent high-intensity exercise (IHE) compared with continuous moderate-intensity exercise (MOD) despite the performance of a greater amount of total work. The purpose of the present study was to determine whether this lesser decline in glycemia can be attributed to a greater increment in...
This study revised articles from the MEDLINE (PubMed) databases and other research sources, with no time limit. To do so, the search strategy adopted was based on (P.I.C.O.) structured questions (from the initials “Patient”; “Intervention”; “Control” and “Outcome”. As keywords were used: Breast Neoplasm, Mastectomy, Mastectomy, Radical; Lymph Node Excision, Surgery, Lymphedema, Breast Cancer-re...
High-intensity intermittent exercise (HIIE) has been applied in competitive sports for more than 100 years. In the last decades, interval studies revealed a multitude of beneficial effects in various subjects despite a large variety of exercise prescriptions. Therefore, one could assume that an accurate prescription of HIIE is not relevant. However, the manipulation of HIIE variables (peak work...
Intermittent claudication is a form of exercise intolerance characterized by muscle pain during walking in patients with peripheral artery disease (PAD). Endothelial cell and muscle dysfunction are thought to be important contributors to the etiology of this disease, but a lack of preclinical models that incorporate these elements and measure exercise performance as a primary end point has slow...
This mini-review summarizes the physiological adaptations to and pathophysiological consequences of intermittent hypoxia with special emphasis given to the pathophysiology associated with obstructive sleep apnea. Intermittent hypoxia is an effective stimulus for evoking the respiratory, cardiovascular, and metabolic adaptations normally associated with continuous chronic hypoxia. These adaptati...
