PURPOSE/OBJECTIVES To evaluate the relationship between nausea and exercise during and after adjuvant cancer treatment (chemotherapy and radiation therapy or chemotherapy alone). DESIGN Secondary data analysis from a longitudinal, single-blinded, three-arm, randomized controlled trial. The trial failed to show a significant effect of an exercise intervention on nausea control (by intent to tr...

We examined the relationship between energy expenditure (in kcal) and epinephrine (Epi), norepinephrine (NE), and growth hormone (GH) release. Ten men [age, 26 yr; height, 178 cm; weight, 81 kg; O(2) uptake at lactate threshold (LT), 36.3 ml. kg(-1). min(-1); peak O(2) uptake, 49.5 ml. kg(-1). min(-1)] were tested on six randomly ordered occasions [control, 5 exercise: at 25 and 75% of the diff...

There are three isoforms of peroxisome proliferator-activated receptor-γ coactivator 1α (PGC-1α) mRNA, which promotes mitochondrial biogenesis in skeletal muscles. Compared with PGC-1α-a mRNA, PGC-1α-b or PGC-1α-c mRNA is transcribed by a different exon 1 of the PGC-1α gene. In this study, effects of exercise intensity and 5-aminoimidazole-4-carboxamide-1β-d-ribofuranoside (AICAR) on isoform-sp...

The purpose of this study was to determine whether the acute hormone response to exercise differed between low intensity blood flow restricted resistance exercise and traditional high-intensity resistance exercise in college-aged women. A total of 13 healthy women (aged 18-25 yrs), who were taking oral contraceptives, volunteered for this randomized crossover study. Subjects performed a session...

We hypothesized that circulating GH would increase only if a threshold of work intensity [corresponding to the anaerobic or lactate threshold (LT)] was exceeded. Ten healthy male volunteers (18-35 yr) first performed ramp-type progressive cycle-ergometer exercise to determine the LT and the maximal oxygen uptake. On subsequent mornings after an overnight fast, each subject performed bouts of 1,...

The effects of in-season, high-intensity interval training on professional male soccer players' running performances were investigated. Twenty-two subjects participated in 2 consecutive training periods of 10 weeks. The first period was considered a control period and was compared with a period where 2 high-intensity interval training exercises were included in the usual training program. Inter...

Introduction Inconsistent results from previous studies of exercise and cognitive function suggest that rigorously designed randomized controlled trials are urgently needed. Here, we describe the design of the Intense Physical Activity and Cognition (IPAC) study, which will assess the impact of a 6-month high-intensity exercise intervention on cognitive function and biomarkers of dementia risk,...

PURPOSE We examined whether exercise-induced lymphocytosis and lymphocytopenia are impaired with high-intensity training. METHODS Eight trained cyclists (VO(2max) = 64.2 ± 6.5 mL · kg(-1) · min(-1)) undertook 1 wk of normal-intensity training and a second week of high-intensity training. On day 7 of each week, participants performed a cycling task, consisting of 120 min of submaximal exercise...

PURPOSE To investigate the association between exercise and glaucoma in a South Korean population-based sample. DESIGN Population-based, cross-sectional study. PARTICIPANTS A total of 11,246 subjects, 40 years and older who underwent health care assessment as part of the 2008-2011 Korean National Health and Nutrition Examination Survey. METHODS Variables regarding the duration (total minu...
