Book excerpt: This study utilized an experimental design testing low, medium, and high intensity warm-up protocols for NCAA Division I 800-meter male and female middle distance runners to determine which result in optimal outcomes in a peak performance, i.e., 800-meter time trial. Mississippi State University student athletes on the Track and Field Team who compete in middle distance running events participated. Among males, results of the repeated measures ANOVA found no significant difference among the three warm-up protocols for the first 400 meters completed. For females, repeated measures ANOVA results found no significant difference among the protocols for the first 200 meters completed. However, at the completion of the 800-meter time trial, a statistically significant difference (p

This book was released on 2017 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Middle distance runners are always searching for ways to improve performance. This study was conducted to see if high intensity interval training (HIIT) on a cycle ergometer could help improve overall performance within 800/1500m runners. It was hypothesized that HIIT would increase performance, through decreasing 1500m times and increasing time to fatigue. Athletes completed two HIIT sessions every week for four weeks. Pre- and post- performance tests: incremental treadmill test (run to volitional exhaustion) and a 1500m time trial. In addition to performance, athlete’s stride length and stride frequency during the 1500m time trial were recorded. No significant changes were seen within performance measures nor stride length and frequency. It was concluded two weekly training sessions of HIIT for four weeks does not significantly increase performance within college Division I 800/1500m athletes.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The present investigation posed the following questions; 1)What are the relative contributions of Plasma Viscosity (PV), Red Blood Cell Deformability Index (RBCDI) and Haematocrit (Hct) to Whole Blood Viscosity (WBV) in elite middle distance runners? 2)What is the relationship between WBV and performance in elite middle distance runners? 3)Is WBV modified by sleeping in a hypoxic environment? 4)Does sleeping in a hypoxic environment increase performance? Methodology. The present investigation was part of a larger study at the Australian Institute of Sport investigating the effect of Intermittent Hypoxic Exposure (IHE) on the performance of elite middle distance runners. IHE was regulated to simulate an altitude of 2650 metres by the use of nitrogen to generate a normobaric-hypoxia sleeping chamber (Oxygen 16.3 %, barometric pressure approximately 710 mmHg). Eleven elite middle distance runners volunteered to participate in the study. All runners were members of the Australian Institute of Sport Development Squad with a time of 232.3 ł 1.4 s for 1500 meters. There was (i) a 5 day testing block pre-IHE (at Altitude 600 m, the results of which were used to allocate runners into either the ALTITUDE or CONTROL group); (ii) 5 nights of IHE (2650 m), (iii) 3 days at home (all athletes resided in Canberra, Altitude 600 metres), (iv) 5 nights of IHE (2650 m), (v) 3 days home (600 m), (vi) 5 nights IHE (2650 m), (vii) a post-IHE 5 day testing block (600 m), (viii) 11 days out of the IHE chamber with no tests (600 m) and (ix) a post-IHE 5 day testing block (600 m). Three performance tests were completed each 5 day testing block. The performance tests included (i) long duration treadmill test (VO2max), (ii) short duration treadmill test (anaerobic capacity) and (iii) a 1500 m time trial on a synthetic 400 m track. Blood was collected from a superficial forearm vein on nine occasions. Of the nine occasions blood was collected, three were in the mornings immediately proceeding the 1500 m time trials, three were in the mornings following the first night of exposure in the IHE and the remaining three blood samples were collected in the mornings following the fifth night of exposure to the IHE. Blood was analysed for WBV, PV, Hct, Hb, Red Blood Deformability Index (RBCDI), Red Blood Cell Count (RBCC), White Blood Cell Count (WBCC), red blood cell Mean Cell Volume (MCV), percent Reticulocytes (% retics), Platelet Count (PC) and Mean Cell Volume of the Reticulocyte (MCVr). Results. 1.) 1500 m time trial results for the ALTITUDE and CONTROL groups over the three 5 day testing blocks were 241.3 ł 3.0 s vs 241.7 ł 1.9 s, 243.3 ł 1.4 s vs 238.6 ł 1.8 s and 236.6 ł 2.0 s vs 236.2 ł 0.8 s respectively. Long duration treadmill test (VO2max) time to exhaustion results for the ALTITUDE and CONTROL groups over the three 5 day testing blocks were 612 ł 18.4 s vs 588 ł 24.1 s, 645 ł 6.9 s vs 606 ł 24.1 s and 654 ł 10.2 s vs 645 ł 25.5 respectively. Short duration treadmill test to exhaustion results for the ALTITUDE and CONTROL groups over the three 5 day testing blocks were 120 ł 8.6 s vs 129 ł 12.5 s, 113 ł 2.9 s vs 126 ł 7.2 s and 146 ł 7.8 s vs 145 ł 10.7 s respectively. 2.) A significant (p=0.0004) and positive relationship was found between PV and WBV, Hct and WBV (p=0.0001), Hb and WBV (p=0.0001), RBCC and WBV (p=0.04), WBCC and WBV (p=0.04) and PC and WBV (p=0.01). A significant (p=0.05) and negative relationship was found between RBCDI and WBV. No significant relationship was found to exist between WBV and MCV, WBV and Percent Reticulocytes or WBV and MCVr. 3.) A significant (p=0.002) and positive relationship was found to exist between 1500 m time trial time and WBV and a significant (p=0.001) but negative relationship between 1500m time trial-time and Hct. No significant relationship was found to exist between the long duration treadmill test run time to exhaustion (aerobic capacity) and WBV. A significant (p=0.01) and positive relationship was found to exist between Hct and the long duration treadmill test run time to exhaustion. No significant relationship was found to exist between the short duration treadmill test time to exhaustion (anaerobic capacity) and WBV. A significant (p=0.02) and positive relationship was found to exist between short duration treadmill test time to exhaustion and Hct. 4.) Intermittent Hypoxic Exposure resulted in a significant elevation of WBV (p=0.001) in the ALTITUDE group compared to the CONTROL group over the course of the study. 5.) In elite middle distance runners, 15 nights of sleeping in IHE did not significantly improve anaerobic (short duration treadmill test), aerobic (long duration treadmill test) performance, or 1500 m time, any more than sleeping in normoxic (600 m) conditions. Conclusions. i) PV, RBCDI and Hct do significantly and positively contribute to WBV. ii) A significant and positive relationship exists between WBV and WBCC and WBV and PC. iii) There was a paradoxical situation in elite middle distance runners between WBV and 1500 m time trial time and Hct and 1500m time trial time. Increased WBV leads to slower 1500 m time trial times and a shorter time to exhaustion. Increased Hct leads to faster 1500 m time trial times and a longer time to exhaustion. We conclude; (1) that there exists an optimal combination of Hct and WBV to produce optimal performance in elite middle distance runners. (2) Whole blood is significantly more viscous as the result of IHE. (3) Intermittent hypoxic exposure did not improve 1500 m time trial performance, aerobic or anaerobic capacity in an elite middle distance runners.
Book Synopsis The Effects of a Sub-maximal Warm-up on Endurance Performance in Trained Male Runners During a 30-minute Time Trial by : Caleb Bazyler
Download or read book The Effects of a Sub-maximal Warm-up on Endurance Performance in Trained Male Runners During a 30-minute Time Trial written by Caleb Bazyler and published by . This book was released on 2010 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: A sub-maximal running warm-up has been shown to increase endurance performance; however there have been conflicting results. The purpose of this study was to investigate the effects of a sub-maximal warm-up (SWU) on running endurance performance during a 30-minute time trial in trained male runners. Ten well trained male distance runners aged 21 ± 2 yrs with an average VO2max of 67.5 ± 4.7 mL/kg/min were recruited. Subjects reported to the laboratory on 4 separate days. On day 1, anthropometrics and VO2max were determined. On days 3 and 4, subjects were randomly assigned to either a SWU consisting of a 6-minute run at 45, 55, and 65% VO2max (2 minutes each) followed by a 2-minute walk at 2 mph; or sat quietly for 8 minutes (Control). Afterwards both conditions performed a 30-minute time trial in which they were instructed to run as far as possible. Average VO2 and resting temperature values increased significantly from pre-SWU (4.6 ± 1.1 mL/kg/min), (36.3 ± 0.5 C°) to post-SWU (12.8 ± 1.0 mL/kg/min), (36.4 ± 0.5 C°) but did not change in the Control (4.7 ± 0.6 to 5.0 ± 1.3 mL/kg/min), (36.1 ± 0.3 to 36.2 ± 0.4 C°). There was no significant difference in distance run between SWU (4.8 ± 0.3 miles) and Control (4.7 ± 0.4 miles). These findings suggest that a 6-minute SWU does not significantly affect endurance performance in well trained male runners during a 30-minute time trial.

Download or read book The Effects of Elapsed Time After a Warm Up on Physiological and Performance Responses During Rowing and Running in a Cold Environment written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Competitive rowers among other athletes, compete in relatively cold environmental conditions. A warm-up is a standard procedure in all sports, and athletes complete it in order to increase body metabolism and tissues. Delays that occur before races can force rowers to be constrained to their boat and lose the effects of the warm-up. Quick racing starts following long delays do not allow time for additional warm-up; therefore, performance during the race may be affected, which is important since rowers perform supramaximally for about 6 to 8 minutes. This combination of intensity and duration does not give the body enough time to benefit from gradual warm-up effects that occur during the first few minutes of exercise at a lower intensity. Purpose: The purpose of this study is to examine the effects of varied durations of post warm-up periods on the metabolic, thermoregulatory, and performance responses during subsequent high intensity rowing or running in a cold environment. Method: Five experienced rowers (1 female; 4 male) and five trained runners (2 female; 3 male) completed four trials consisting of a standardized warm-up followed by: 5 minutes of rest in room temperature (5-R); 5 minutes of rest in the cold (5°C) (5-C); 30 minutes of rest in room temperature (30-R); 30 minutes of rest in the cold (30-C). After the resting period, rowers performed a 2000 meter time trial on a rowing ergometer and runners performed a 1.5 mile time trial on a treadmill. Blood samples were collected pre-exercise, post-warm-up, pre- and post-time trial and 3 minutes post-time trial and were analyzed for lactate concentration in all participants, and pH and bicarbonate (HCO3- ) in the rowers. Core temperature (Tc) was measured via an esophageal probe, skin temperature (Tsk) was measured via surface probes on four sites of the body, and heart rate (HR) was measured via a Polar monitor. These variables were measured every five minutes during the warm-up and resting period, an.

This book was released on 2014 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this study was to investigate the separate and combined effects of precooling and warm-up on a subsequent cycling time trial in a hot environment. METHODS: Nine healthy men (mean ±SD age=24±5 years; body mass=74.7±4.5 kg; height=171.4±7.7 cm; body fat=12.9±5.2%) completed 3 simulated 16.1-km time trials on a cycle ergometer in a hot environment (~33 °C, 45% relative humidity) after: 1) 20 min of fluid ingestion (10 °C) followed by 30 min of ice-slurry ingestion ( -1 °C) coupled with ice-vest (PREC), 2) 30 min of ice-slurry ingestion coupled with ice-vest followed by 20 min of warm-up including ice-slurry and ice-vest (COMBO), 3) 30 min of fluid ingestion (10 °C) followed by 20 min of warm-up (WU). RESULTS: At baseline, rectal temperature (T_re), mean skin temperature (T̄̄_sk), and mean body temperature (T̄_b) were similar among treatments (all P>0.05). After treatment administration and before the start of the time trial, T_re was lower in PREC (36.1±0.3) and COMBO (36.9±0.4) compared to WU (37.6±0.2) (all P0.05). T̄_sk and T̄_b were all lower in PREC than COMBO and WU, and were lower in COMBO than WU (all P0.05). Tre remained lower in PREC than WU throughout exercise and was lower in PREC than COMBO for the first 12 km (all P0.01), while T_re in COMBO remained lower than WU for the first 4 km. T̄_sk during PREC was lower than COMBO at 4 and 8 km and lower than WU at 0 and 4 km, while during COMBO it was lower than WU at 0 and 4 km (all P

Book Synopsis The Effects of Wearing a Cooling Vest During the Warm-up on Long Distance Interval Training by : Andrew Robert Tegeder
Download or read book The Effects of Wearing a Cooling Vest During the Warm-up on Long Distance Interval Training written by Andrew Robert Tegeder and published by . This book was released on 2006 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reducing body temperature before exercise is called precooling. Past research suggests that reducing body core temperature (Tc) slightly can result in improved running performance. This study evaluated the effects that warming up, while wearing a cooling vest prior to an interval workout, had on Tc, and interval time in long-distance runners. Methods: Nineteen healthy male collegiate cross-country runners were recruited for this study. Each subject warmed up and exercised under two different conditions: (a) an experimental condition in which subjects wore a Nike PreCool?? ice vest during warm-up and (b) a control condition. Subjects performed a warm-up followed by running eight 1000 m intervals separated by 90 s of rest. Heart rate (HR) and Tc were measured prior to warm-up, just prior to start of the first interval, and after each interval. Results: Tc measured directly prior to the first interval was significantly lower in the vest condition than the non-vest condition (difference = 0.37?XC; P
