Manipulating high-intensity interval training: Effects on , the lactate threshold and 3000m running performance in moderately trained males

The effects of single versus twice daily short term heat acclimation on heat strain and 3000m running performance in hot, humid conditions

“…Consequently, for moderately trained individuals used within the study, there b b b ' merely reflect a reduction in perceived exertion and improved thermal comfort under heat stress. Previous studies investigating various interventional strategies on 3 km performance, include intermittent hypoxic (Stray-Gundersen, et al, 2001;Katayama, et al, 2003Katayama, et al, , 2004Rodriguez et al, 2007), plyometric (Spurrs et al, 2003;Pellegrino et al, 2015) and intense training periods (Smith et al, 1999;Coutts, et al, 2007;Esfarjani, et al, 2007), reporting a vast range in improvements from 0.8 to 7.3%. However, the le ' aerobic fitness level, running experience, length and method of intervention vary considerably and so comparisons to this study must be interpreted lightly.…”

Performance Training Guidelines for the 1.5 and 2-Mile Runs

“…Because anaerobic factors play a greater role in middle distances than longer runs, increasing LT is likely to improve performance in 1.5 and 2-mile runs. Alterations in LT likely require training at or above LT. 22,23 …”

“…47,48 Denadai et al 42 showed in well-trained runners, that training at 100% of vVO2max twice a week for 8 weeks leads to an increase in vVO2max without significant changes in VO2max. Because of the improvements in 1500 m, 3000 m and 5000 m trials, 23,28,29 it is reasonable to infer that training with this method may also improve 1.5 and 2-mile test performance. Billat et al 46 found that performing only one interval training session per week at vVO2max (along with several runs at onset of blood lactate accumulation) was sufficient to increase vVO2max and running economy after four weeks of training.…”

Reduced volume but increased training intensity elevates muscle Na+-K+ pump α1-subunit and NHE1 expression as well as short-term work capacity in humans

“…In addition, Bickham et al (4) reported change in the MCT1 transport proteins in endurance-trained subjects after a period of sprint training, but in this study the participants had maintained a great portion of their weekly endurance training volume, and thus the combined effect of endurance and high-intensity training was studied. Thus, although a num-ber of studies have shown improvements in specific performance tests after a period with elevated training intensity of already trained individuals (4,10,25), little is known about the effect of such training regimes on muscle ion transport proteins and their relationship with muscle fatigue development during intense exercise.…”
