The Significance of Time to Exhaustion at the Velocity at VO2MaxEhler, Karen 05 1900 (has links)
There were two primary goals in this investigation. The first goal was to determine if inter-individual variability in time to exhaustion at the velocity associated with V02max (Tlim at Vmax) was explained by anaerobic capacity (AC), Vmax, anaerobic threshold (AT), and/or a combination variable in the form [AC • (Vmax - vAT)^-1]. The second goal was to determine if AC could be predicted from Tlim at Vmax, AT, and/or a combination variable in the form [Tlim • (Vmax - vAT)].

Plantar forces during forward ice hockey skating : comparison between ice and treadmill conditionsLoh, Jonathan James January 2003 (has links)
This study compared the plantar force distribution between forward ice hockey skating and treadmill skating. Four varsity hockey players from McGill University (age = 22.1 +/- 1.2 years, height = 1.8 +/- 0.1 m, mass = 82.2 +/- 8.6 kg) skated on ice surface and on a specialized treadmill at three velocities (22, 24 and 26 +/- 0.5 km/hr). Results showed higher plantar forces were seen during treadmill skating prior to push off and this discrepancy was due to consistently larger forces in the fore region of the foot. This phenomenon was speculated to be the result of differences in skate stability during ice and treadmill skating. With respect to the loading dynamics, the heel region was the same during ice and treadmill skating.

Skate blade hollow and oxygen consumption during forward skatingMorrison, Paul January 2003 (has links)
The purpose of this study was to investigate the effect of skate blade hollow on oxygen consumption during forward skating on a treadmill. Varsity level female hockey players ( n = 10, age = 21.7 yr) performed skating tests at three blade hollows (0.25 in, 0.50 in, and 0.75 in). The subjects skated for four minutes at three submaximal velocities (12, 14, and 16 km/h), separated by five minutes of passive recovery. In addition, a VO^max test was performed on the day that the subjects skated at the 0.50 in hollow. The VOimax test commenced at 14 km/h and increased by 1 km/h each minute until volitional exhaustion was achieved. Four variables were measured for each skating bout, volume of gas expired (VE), volume of oxygen consumed (VO2), heart rate (HR) and rating of perceived exertion (RPE). No significant differences (pO.05) were found in any of the four test variables (VE, VO2, HR, RPE) across the three skate hollows. These results show that when skating on a treadmill at submaximal velocities, skate blade hollow has no significant effect on VE, VO2, HR or RPE.

Evaluation of a new standardized modified ramp protocol : the modified BSU ramp protocolHorn, Stacey Lynn January 1999 (has links)
The purpose of this study was to develop a prediction equation for peak oxygen uptake using the Modified BSU Ramp protocol. Thirty-four subjects (14 men and 20 women, age 32-83 years) completed the standard Ball State University Adult Physical Fitness Program quiet and exercise testing sessions, with the maximal exercise test conducted with the Modified BSU Ramp protocol. The modified ramp protocol increases speed and grade every 20 seconds, and it increases by - 0.15 METs every increment for the first 6 minutes and --0.3 METs per increment thereafter. The Modified BSU ramp protocol was developed to allow for reasonable exercise test times from a standardized ramp protocol with individuals with low functional capacities < 10 METs. Pre-test procedures included height and weight measurements, resting blood pressure, resting heart rate, body fat measures, a blood lipid profile, and resting electrocardiogram (ECG). Exercise testing included ECG, heart rate, and blood pressure that were recorded prior to, during, and in the recovery phase of exercise. Subjects were instructed to continue exercise until fatigue, and respiratory gases were collected to determine V02 . Data was then analyzed using multiple regression techniques. Gender, age, body weight, and treadmill test time were the significant predictors, which were used in the regression equation (R2 = 0.586, SEE = 3.54 ml-kg-'.min'). An equation was developed from the lone predictor, treadmill test time with R2 = .37 and SEE = 4.1 ml•kg'•min'. The equation is as follows: VOA = 4.932 + 1.934 (test time (min)). Of the tests conducted on the Modified BSU ramp protocol, 82% were within an "ideal" test time window of 812 minutes, and 97% were within an "acceptable" test time window of 6-15 minutes. In conclusion, VOA can be estimated with acceptable accuracy (i.e. SEE - ± I MET) from the Modified BSU Ramp protocol, and for clinical purposes it is a suitable protocol to use when testing low fit individuals. / School of Physical Education

A comparative study of exercise blood pressure using the Bruce treadmill test and the 3-3-3 exercise testNaftzger, Lisa A. January 1992 (has links)
The purpose of this study was to compare the exercise blood pressure response of subjects with a history of exercise induced hypertension between the submaximal 3-3-3 exercise test and a maximal Bruce treadmill protocol. Seven male and four female subjects with a mean age of 49 ± 2 years were recruited for the study. All subjects were selected based on a previous elevation of exercise diastolic blood pressure >_ 10 mmHg during maximal exercise.The 3-3-3 test is a short, standardized treadmill test protocol that consists of one stage of treadmill walking at a 3% grade, at 3 miles per hour, for 3 minutes. Subjects completed the 3-3-3 test on one day and the Bruce protocol on a different day with 24-48 hours between tests. Test administration order was randomized and all tests were done at the same time of the morning with all blood pressures taken by the same technician with a mercury manometer.The increase in diastolic pressure from rest was significantly lower (p<0.004) during the 3-3-3 protocol compared to the peak of the Bruce protocol. There were no statistical differences between the change in diastolic pressure from rest to peak exercise when the 3-33 protocol was compared to the Bruce Stage I or when the Bruce Stage I was compared to the peak Bruce diastolic measurement. The mean change in diastolic pressure from rest to peak exercise in the3-3-3 protocol was 3.4 ± 2.6 mmHg as compared to 9.9 ± 2.0 mmHg for the Bruce Stage I, and 15.4 ± 2.4 mmHg from rest to peak exercise with the peak Bruce. There were no differences in resting or standing systolic or diastolic blood pressure values between protocols done on separate trial days. The change in systolic response from rest to peak exercise and the peak systolic pressures were significantly different (p<0.001) between the Bruce Stage I and peak Bruce and between the 3-3-3 and peak Bruce. There were no significant differences in the heart rate and rate pressure product between the third minute of the 3-3-3 protocol and the third minute of the Bruce Stage I (p<0.001).The 3-3-3 test was not able to elicit the same rise in diastolic blood pressure as the Bruce treadmill test in this population, although the Bruce Stage I was able to elicit a response that was not statistically different than the response of the peak Bruce protocol. This implies that submaximal treadmill testing may be a feasible method to screen for the presence of an exaggerated diastolic blood pressure response to exercise. / School of Physical Education

Forward skating in ice hockey : comparison of EMG activation patterns of [sic] at three velocities using a skate treadmillGoudreault, Robin. January 2002 (has links)
This study investigated the EMG muscle activation patterns of forward ice hockey skating at three velocities. Seven varsity hockey players from McGill University (age = 22.1 +/- 1.2 years, height = 1.8 +/- 0.1m, weight = 82.1 +/- 8.5 kg) participated. Testing was done using a skating treadmill. Skin was shaved, abraded and cleansed in the area of the electrode placement over the vastus medialis (VM), adductor magnus (AM), biceps femoris (BF), gluteus maximus, tibialis anterior (TA), peroneus longus (PL), and lateral gastrocnemius (GL) of the right lower limb. Subjects skated at 12 km/hr, 18 km/hr, and 24 km/hr. Repeated measures ANOVAs were performed, followed by Tukey post hoc tests. In general, the amplitude at speed 24km/hr was significantly higher than the speed of 12km/hr. There were few significant differences in temporal values. In conclusion, this study has shown that an increase in velocity results in an increase in the amount of muscle activation, but the muscle coordination patterns remain the same.
