Physiological and perceptual responses at ventilatory threshold (VT) and V̇O2 peak were examined in 10 male children (10.2 ± 1.3 yrs) during graded treadmill and cycle exercise. Treadmill V̇O2peak (57.9 ± 6.7 ml · kg−1 · min−1) was higher (p < .05) than the cycle (51.7 ± 7.7 ml · kg−1 · min−1). Ventilation and heart rate (HR) were higher (p < .05) on the treadmill, while respiratory exchange ratio (RER), rating of perceived exertion (RPE), capillary blood lactate, and test duration were similar between tests. The V̇O2 at VT was higher (p < .05) on the treadmill (36.7 ± 4.6 ml · kg−1 · min−1) than the cycle (32.5 ± 4.4 ml · kg−1 · min−1). When VT was expressed as a percentage of V̇O2 peak, there was no difference (p > .05) between tests. The RPE at VT, HR at VT, and VT expressed as a percentage of HRpeak were also similar (p > .05) between tests. Similar to V̇O2 peak, the V̇O2 at VT is dependent on the mode of exercise. However, when VT is expressed as a percentage of V̇O2 peak, it is independent of testing modality. The RPE at VT appears to be linked to a percentage of V̇O2 peak rather than an absolute V̇O2.

Undergraduate research is emphasized as a critical component of today’s science-based undergraduate education and widely accepted as an important part of the overall undergraduate education experience. While educators agree on the value of undergraduate research, significant challenges exist related to the design of the undergraduate research experience and the faculty member’s role in it. Additional challenges include providing high-quality research experiences that benefit the education of a large number of students while maintaining feasibility and cost-effectiveness. The scope of this review is to provide an overview of research and service-learning experiences in kinesiology departments at 3 institutions of higher learning that vary in size and mission.
