The Impact Of The Cold Pressor Test On Inter-Arm Differences In Blood Pressure, Alyssa C. Watts, Lauren A. Naylor, Michael E. Holmstrup, Brock T. Jensen

International Journal of Exercise Science

International Journal of Exercise Science 16(2): 875-884, 2023. A large inter-arm difference (IAD+; ≥10mmHg between arms at rest) in blood pressure (BP) at rest is linked to cardiovascular risk, and exercise can change this difference. As mechanisms for IAD are elusive, unique physiological stimuli may provide insight towards a better understanding of this phenomenon. The cold pressor test (CPT) has a potent effect on BP and acts primarily through sympathetic nervous system (SNS) stimulation, though the effects of SNS stimulation on IAD are unknown. Therefore, the purpose of the present study was to examine the effects of the CPT on …

International Journal of Exercise Science

International Journal of Exercise Science 16(2): 866-874, 2023. The purpose of this pilot study was to determine if there is a difference in metabolic cost when jumping on platforms of varying thickness, as well as whether a difference exists in metabolic cost between genders exists on the different platforms. Fourteen participants (seven males and seven females) completed three repetitive jumping trials on the DigiJump machine. Each trial was performed at a cadence of 120 jumps per minute and at a minimum height of 1/2” per jump. Trials were completed on platforms of 1/2”, 3/8”, and 1/4” thickness. Participants were instructed …
