UNLABELLED The warm-up procedure in traditional rowing usually involves continuous low-intensity rowing and short bouts of intense exercise, lasting about 60 min. PURPOSE To compare the effects of a traditional and an experimental 30-min warm-up of lower intensity on indoor rowing time-trial performance. METHODS Fourteen highly trained male rowers (age 25.9 ± 5.3 y, height 1.86 ± 0.06 m, ma...

This study assessed whether the elevated sensitivity of ventilation to hypoxia during exercise is accounted for by an elevation of esophageal temperature (T(es)). Eleven males volunteered for two exercise sessions on an underwater, head-out cycle ergometer at a steady-state rate of oxygen consumption (V(.)(O(2))) of approximately 0.87 l/min (SD 0.07). In one exercise session, 31.5 degrees C (SD...

The aim of this study was to examine the acute effects of pre- performance lower limb massage after warm-up on explosive and high-speed motor capacities and flexibility. Twenty-four physically active healthy Caucasian male subjects volunteered to participate in this study. All subjects were from a Physical Education and Sport Department in a large university in Turkey. The study had a counterba...

OBJECTIVE To determine the efficacy of warm whirlpool, cold whirlpool, and contrast therapy in the treatment of delayed-onset muscle soreness. DESIGN AND SETTING Subjects performed eccentric contractions of the elbow flexors and received 4 treatments: immediately postexercise and 24, 48, and 72 hours postexercise. Treatments consisted of 24-minute treatments with warm whirlpool, cold whirlpoo...

BACKGROUND Preoperative simulation warm-up has been shown to improve performance and reduce errors in novice and experienced surgeons, yet existing studies have only investigated conventional laparoscopy. We hypothesized that a brief virtual reality (VR) robotic warm-up would enhance robotic task performance and reduce errors. STUDY DESIGN In a 2-center randomized trial, 51 residents and expe...

This investigation was conducted to determine the effect of 2 different warm-up treatments over time on driver clubhead speed, distance, accuracy, and consistent ball contact in young male competitive golfers. Two supervised warm-up treatments, an active dynamic warm-up with golf clubs (AD) and a 20-minute total body passive static stretching routine plus an identical AD warm-up (PSS), were app...

on the 2nd January, 1932, about three inches below the left knee on the outer aspect of the leg. History.?He was bitten while cutting grass and was brought to me at about 3-30 p.m. Condition on admission.?The patient was unconscious, pulse feeble, respirations hurried and 48 per minute, body and extremities fairly warm and perspiring freely. Pupils?dilated. Treatment adopted.?A ligature was imm...

Vocal warm-ups are widespread and comprehensive in the singing community. Although it is well recognised practised by professionals, sometimes bypassed neglected singers voice teachers. The objective of this study to assess impact vocal warm-up on quality through acoustic parameters jitter (%), shimmer harmonics-to-noise (HNR [dB]) two-pitch conditions, A3 (chest register) C5 (head register), b...

BACKGROUND The safe duration of warm ischemia during partial nephrectomy remains controversial. OBJECTIVE Our aim was to evaluate the short- and long-term renal effects of warm ischemia in patients with a solitary kidney. DESIGN, SETTING, AND PARTICIPANTS Using the Cleveland Clinic and Mayo Clinic databases, we identified 362 patients with a solitary kidney who underwent open (n=319) or lap...

The purpose of this study was to investigate the effects of a low-load gluteal warm-up protocol on countermovement and squat jump performance. Research by Crow et al. (2012) found that a low-load gluteal warm-up could be effective in enhancing peak power output during a countermovement jump. Eleven subjects performed countermovement and squat jumps before and after the gluteal warm-up protocol....
