No Intervention: Usual Care Group
The usual care group will be provided with standard active surveillance medical care.

- Changes of Peak Oxygen Consumption (VO2peak) [ Time Frame: At baseline and 12-week (postintervention) ]VO2peak is a measure of cardiopulmonary fitness and a powerful surrogate outcome for cancer-specific and overall survival. VO2peak will be defined as the highest oxygen-uptake value recorded during the test and quantified where participants reach a plateau in oxygen consumption, which will be expressed as relative to body mass (i.e., ml O2·kg-1·min-1).
- Changes of Natural Killer Cell Cytotoxic Activity (NKCA) and Counts [ Time Frame: At baseline and 12-week (postintervention) ]NKCA significantly contributes to the regulation of tumour suppression in response to exercise and it has been demonstrated to have a diagnostic value in patients with cancer. NK cell activities are assessed using blood analysis as the total number of circulating NK cells and their cytotoxic activity. NK cell counts and NKCA will be measured using the phenotypic markers of NK cells (CD3-CD16+CD56+). NKCA will be expressed as the percentage of target cells killed by a sample of 100,000 peripheral blood mononuclear cells at the effector-to-target ratios of 5:1, 20:1, 40:1, and 100:1.
- Changes of Immune-Related Phenotype [ Time Frame: At baseline and 12-week (postintervention) ]Immune-related phenotypic markers, including CD3, CD16, CD56, and CD107 (on the frozen) and CD4, CD8, CD20, CD25, CD11, CD45RA, CD45RO, CD16, CD56, CD107 activation (fresh on whole blood), will be assessed using blood samples.
- Changes of Prostate-Specific Antigen (PSA) [ Time Frame: At baseline, 12-week (postintervention) ]PSA will be assessed using blood samples.
- Changes of Complete Blood Count with Differential (CBCD) [ Time Frame: At baseline and 12-week (postintervention) ]CBCD, including RBC, WBC, HGB, HCT, PLT, LYMPH, BASO, EOS, MONO, NEUT, will be assessed using blood samples.
- Changes of Insulin [ Time Frame: At baseline and 12-week (postintervention) ]Fasting insulin levels will be assessed using blood samples.
- Changes of Fasting Glucose [ Time Frame: At Baseline and 12-week postintervention ]Fasting glucose levels will be assessed using blood samples.
- Changes of HbA1c [ Time Frame: At Baseline and 12-week postintervention ]HbA1c will be assessed using using blood samples.
- Changes of Insulin-like Growth Factor (IGF)-axis [ Time Frame: At baseline and 12-week (postintervention) ]IGF-axis, including circulating IGF-1 and IGF binding protein(IGFBP)-3, will be assessed using blood samples.
- Changes of Pro-Inflammatory Cytokines [ Time Frame: At baseline and 12-week (postintervention) ]Pro-inflammatory cytokines, including IFN-γ, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12p70, IL-13, and TNF-α, will be assessed.
- Changes of High-Sensitivity C-Reactive Protein (hs-CRP) [ Time Frame: At Baseline and 12-week postintervention ]hs-CRP will be assessed using blood samples.
- Changes of Adiponectin [ Time Frame: At Baseline and 12-week postintervention ]Adiponectin will be assessed using blood samples.
- Physical Function [ Time Frame: At Baseline and 12-week postintervention ]Physical function, consisting of strength, flexibility, and agility components, will be assessed by the Senior's Fitness Test (SFT).
- Health-Related Quality of Life [ Time Frame: At baseline, 12-week (postintervention), 6-month, and 12-month ]Health-related quality of life will be assessed using the European Organization for Research and Treatment of Cancer- Quality of Life Questionnaire (EORTC-QLQ) - C30 questionnaire.
- Prostate Cancer-Specific Quality of Life [ Time Frame: At baseline, 12-week (postintervention), 6-month, and 12-month ]Prostate cancer-specific quality of life will be assessed using the Expanded Prostate Cancer Index Composite-26 (EPIC-26) questionnaire.
- Fear of Cancer Progression [ Time Frame: At baseline, 12-week (postintervention), 6-month, and 12-month ]Fear of cancer progression will be assessed using the Fear of Cancer Recurrence Inventory (FCRI) questionnaire.
- Cancer Worry [ Time Frame: At baseline, 12-week (postintervention), 6-month, and 12-month ]Cancer worry will be assessed using the Cancer Worry Scale (CWS) questionnaire.
- General Anxiety [ Time Frame: At baseline, 12-week (postintervention), 6-month, and 12-month ]General anxiety will be assessed using the Anxiety (general): Spielberger State-Trait Anxiety Inventory (STAI) questionnaire.
- Prostate Cancer-Specific Anxiety [ Time Frame: At baseline, 12-week (postintervention), 6-month, and 12-month ]Prostate cancer-specific anxiety will be assessed using the Memorial Anxiety Scale for Prostate Cancer (MAX-PC) questionnaire.
- Depression [ Time Frame: At baseline, 12-week (postintervention), 6-month, and 12-month ]Depression will be assessed using the Epidemiologic Studies Depression Scale (CES-D) questionnaire.
- Perceived Stress [ Time Frame: At baseline, 12-week (postintervention), 6-month, and 12-month ]Perceived stress will be assessed using the Perceived Stress Scale (PSS) questionnaire.
- Self-esteem [ Time Frame: At baseline, 12-week (postintervention), 6-month, and 12-month ]Self-esteem will be assessed using the Rosenberg Self-Esteem Scale (RSES) questionnaire.
- Fatigue [ Time Frame: At baseline, 12-week (postintervention), 6-month, and 12-month ]Fatigue will be assessed using the Functional Assessment of Cancer Therapy- Fatigue (FACT-F) questionnaire.
- Physical Activity Level [ Time Frame: At baseline, 12-week (postintervention), 6-month, and 12-month ]Physical activity level, consisting of light-, moderate-, and vigorous aerobic exercise and resistance exercise, will be assessed using the Godin Leisure-Time Exercise Questionnaire (GLTEQ).
- Exercise Motivation [ Time Frame: At baseline, 12-week (postintervention), 6-month, and 12-month ]Exercise motivation, consisting of Theory of Planned Behaviour (TPB) constructs (instrumental and affective attitudes, subjective norms, intention and perceived behavioral control), will be assessed using questionnaire.
- Body composition [ Time Frame: At baseline and 12-week (postintervention) ]Body composition, including body weight and waist- and hip-circumferences, will be assessed using weight scales and a tape measure.
