Effect Of Seat Tube Angle And Exercise Intensity On Muscle Activity Patterns In Cyclists, Will Duggan, Bernard Donne, Neil Fleming
Effect Of Seat Tube Angle And Exercise Intensity On Muscle Activity Patterns In Cyclists, Will Duggan, Bernard Donne, Neil Fleming
International Journal of Exercise Science
International Journal of Exercise Science 10(8): 1145-1156, 2017. Previous studies have reported improved efficiency at steeper seat tube angle (STA) during ergometer cycling; however, neuromuscular mechanisms have yet to be fully determined. The current study investigated effects of STA on lower limb EMG activity at varying exercise intensities. Cyclists (n=11) were tested at 2 workloads; 160W and an individualised workload (IWL) equivalent to lactate threshold (TLac) minus 10%δ (derived from maximal incremental data), using 3 STA (70, 75 and 80°). Electromyographic data from Vastus Medialis (VM), Rectus Femoris (RF), Vastus Lateralis (VL) and Biceps Femoris (BF) were assessed. …

Rollers Versus Trainers: 10-Km Time Trial, Wayland Tseh, Tate Devlin, Taylor Milleson, T V. Barreira
International Journal of Exercise Science
International Journal of Exercise Science 10(1): 497-505, 2017. The primary aim of this investigation was to determine which cycling training device, Rollers or Trainers, was most effective in improving 10-km time trial. Eight male and 6 female volunteers (N = 14; age = 23.6 ± 4.6 yrs; height = 172.7 ± 9.9 cm; body mass = 68.4 ± 10.4 kg; % body fat = 16.9 ± 7.7; VO2max = 61.0 ± 9.4 ml∙kg-1∙min-1) provided informed consent prior to participation. Participants performed a10-km time trial at baseline and were then randomly assigned into one of three …

Demands Of Simulated Commuting Using An Electrically Assisted Bicycle, D. Taylor La Salle, Robert Shute, Matthew Heesch, Dustin Slivka
International Journal of Exercise Science
International Journal of Exercise Science 10(3): 454-464, 2017. The American College of Sports Medicine (ACSM) recommends adults participate in weekly aerobic activity for a minimum of 30 minutes moderate intensity exercise 5 days per week or 20 minutes of vigorous activity 3 days per week. The electrically assisted bicycle may help individuals achieve the ACSM’s aerobic recommendations and introduce inactive individuals to physical activity. To compare the physiological requirements of riding a bicycle with electric pedal assist versus non-assist among healthy active young adults. 6 males and 6 females completed two randomized cycling trials using electric pedal assist (PAB) and …
