Fatigue-Related Feedback From Calf Muscles Impairs Knee Extensor Voluntary Activation, Harrison T. Finn, David S. Kennedy, Simon Green, Janet L. Taylor

Research outputs 2014 to 2021

INTRODUCTION:

Fatigue-related group III/IV muscle afferent firing from agonist, antagonist or distal muscles impairs the ability to drive the elbow flexors maximally, that is, reduces voluntary activation. In the lower limb, the effect of feedback from distal muscles on the proximal knee extensors is unknown. Here, we test whether maintained group III/IV afferent feedback from the plantarflexor muscles reduces voluntary activation of the knee extensors.

METHODS:

On 2 d, voluntary activation of the knee extensors during maximal voluntary contractions (MVCs) was assessed in 12 participants before and after a 3-min fatiguing task of the plantarflexors. On 1 d, an inflatable …

The Effects Of Environmental Temperature On High-Intensity Interval Training, Jason R. Boynton

Theses: Doctorates and Masters

Endurance athletes typically spend the large majority of training (> 70%) at low intensities (i.e. below lactate threshold) coupled with short and intermittent bouts of high-intensity exercise or interval training (HIIT). Despite HIIT being a relatively small part of training in terms of duration, it has a substantial effect on the adaptations to endurance training. While it is well-established endurance exercise performance is affected in both hot and cold environmental conditions, the effect ambient temperature (TA; frequently referred to as environmental temperature) has on HIIT as performed by an endurance athlete population is not well understood. Therefore, the overall purpose …

Exercise And Nutrition Induced Weight Loss For Prostate Cancer Patients, Rebekah Louise Wilson

Theses: Doctorates and Masters

This thesis encompasses six main chapters - two reviews and four experimental chapters, in addition to a general introduction and discussion.

Review 1 (Chapter 2) is a discussion of the negative impact of obesity on prostate cancer prognosis and common prostate cancer treatments.

Review 2 (Chapter 3) is an evaluation of the current literature examining prostate cancer patients receiving androgen deprivation therapy (ADT) and how exercise and nutrition interventions can be used to induce fat loss, while preserving or improving lean mass.

Study 1 (Chapter 4) is an examination of the efficacy of a weight loss program in altering body …
