“…Many studies have shown that v _ V V O 2max is a velocity that well-trained runners maintain over 3000 m (Babineau and Leger 1997;Jones 1998). Previous work from our laboratory reported that v _ V V O 2max is also useful as a training intensity prescriptor (Smith et al 1999).…”

The aim of this study was to compare the effects of two high-intensity, treadmill interval-training programs on 3000-m and 5000-m running performance. Maximal oxygen uptake (.VO(2max)), the running speed associated with .VO(2max) (v.VO(2max)), the time for which v.VO(2max) can be maintained (T(max)), running economy (RE), ventilatory threshold (VT) and 3000-m and 5000-m running times were determined in 27 well-trained runners. Subjects were then randomly assigned to three groups; (1) 60% T(max), (2) 70% T(max) and (3) control. Subjects in the control group continued their normal training and subjects in the two T(max) groups undertook a 4-week treadmill interval-training program with the intensity set at v.VO(2max) and the interval duration at the assigned T(max). These subjects completed two interval-training sessions per week (60% T(max)=six intervals/session, 70% T(max) group=five intervals/session). Subjects were re-tested on all parameters at the completion of the training program. There was a significant improvement between pre- and post-training values in 3000-m time trial (TT) performance in the 60% T(max) group compared to the 70% T(max) and control groups [mean (SE); 60% T(max)=17.6 (3.5) s, 70% T(max) =6.3 (4.2) s, control=0.5 (7.7) s]. There was no significant effect of the training program on 5000-m TT performance [60% T(max)=25.8 (13.8) s, 70% T(max)=3.7 (11.6) s, control=9.9 (13.1) s]. Although there were no significant improvements in .VO(2max), v.VO(2max) and RE between groups, changes in .VO(2max) and RE were significantly correlated with the improvement in the 3000-m TT. Furthermore, VT and T(max) were significantly higher in the 60% T(max) group post- compared to pre-training. In conclusion, 3000-m running performance can be significantly improved in a group of well-trained runners, using a 4-week treadmill interval training program at v.VO(2max) with interval durations of 60% T(max).

“…With longer periods of high workload and shorter periods of recovery, interval-like exercise comes close to a constant workload performance [2]. In this respect, the course profile with the (variable) succession of climbs and descents determines how close a MTB race is to constant load exercise, such as road racing time trials.…”

This study aims at describing the workload demands during mountain bike races using direct power measurements, and to compare these data to power output and physiological findings from laboratory exercise tests. Power output (P, Watt) from 11 national team cyclists (9 male, 2 female) was registered continuously during 15 races using mobile crank dynamometers (SRM System). To evaluate the intensity of racing, incremental exercise tests with determination of P at aerobic and anaerobic thresholds (AT, IAT) and at exhaustion (MAX) were performed. Intensity zones were determined (zone 1 < AT; AT < zone 2 < IAT; IAT < zone 3 < MAX; zone 4 > MAX) and time spent during racing in these zones was calculated. Based on power output measurements P during racing was 246 +/- 12 W (male) and 193 +/- 1 W (female). P showed high variation throughout the race. In contrast heart rate (HR) was relatively stable during racing (male 177 +/- 6 bpm, female 172 +/- 7 bpm). 39 +/- 6 % of race time were spent in zone 1, 19 +/- 6 % in zone 2, 20 +/- 3 % in zone 3 and 22 +/- 6 % in zone 4. MTB races are characterized by a high oscillation in P with permanently elevated HR. A highly developed aerobic and anaerobic system is needed to sustain the high variation in workload.

“…Interval exercise protocols have been extensively studied in various, fixed work-to-rest ratios (from 5:1 to 1:11), and recommended for developing aerobic and anaerobic adaptations [3, 18, 31]. Therefore, this type of training is very popular in swimming practice for improving swimming velocity ( v ) [5, 17].…”

Short duration repeated maximal efforts are often used in swimming training to improve lactate tolerance, which gives swimmers the ability to maintain a high work rate for a longer period of time. The aim of the study was to examine the kinematics of swimming and its relation to the changes in blood acid-base status and potassium level. Seven collegiate swimmers, with at least 6 years of training experience, volunteered to participate in the study. The test consisted of 8 x 25 m front crawl performed with maximum effort. The rest period between repetitions was set to five seconds. Blood samples were taken from the fingertip at rest, after warm-up and in the 3rd minute after completion of the test. The swimming was recorded with a video recorder, for later analysis of time, velocity and technique (stroke index). Based on the swimming velocity results, the obtained curve can be divided into rapid decrease of velocity and relatively stable velocities. The breaking point of repetition in swimming velocity was assumed as the swimming velocity threshold and it was highly correlated with the decrease of the blood acid-base status (pH r=0.82, BE r=0.87, HCO3 - r=0.76; p<0.05 in all cases). There was no correlation between stroke index or fatigue index and blood acid-base status. Analysis of the swimming speed in the 8 x 25 m test seems to be helpful in evaluation of lactate tolerance (anaerobic capacity) in collegiate swimmers.
