Abstract:
The purpose of this study was to determine the effects of a 36 session COREPOWER machine training intervention and those of a 36 session home-based core training intervention programme on golfers' physical fitness and sport specific performance. It was hypothesised that both modalities will improve on golf related fitness aspects. Subjects comprised of experienced golfers and were randomly divided into a machine group (M: n = 51) and a home group (H: n = 50). The following variables were measured both pre- and post-intervention: lower back flexibility (sit & reach), muscle endurance (sit-ups and push-ups), muscle strength (wall-squats and back dynamometer), cardio-respiratory fitness (3 minute step-test), balance (Biodex Balance System), club head speed and carry distance (Flightscope). The Wilcoxon and Mann-Whitney signed-rank test was used to compare pre and post-intervention measurements within each group with significance set at p < 0.05. An ANCOVA analyses was also run as well as Pearson Product Moment correlations. Results portrayed that with the exception of cardiorespiratory fitness, all variables in both groups showed significant (p<0.05) improvement post intervention. Push-ups (p = 0.000; ↑17.03%; d = 0.92) and driver carry distance (p = 0.000; ↑30.30%; d = 0.40) showed the greatest percentage improvement post intervention within group M, while sit-ups (p = 0.000; ↑14.41%; d = 0.77) and push-ups (p = 0.000; ↑12.52%; d = 0.90) showed the greatest percentage improvement within group H. Lower back strength holds significant correlation to golf performance. Thus both modalities, the COREPOWER machine training and the home-based manual core training were equally effective in improving selected fitness components; however the machine was more effective in improving golf performance parameters. These observations can be applied to golfers in addition to their usual golfing activities as well as to other sport populations as this study formed an evidence base for core training.

Exercise and Muscle Performance
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes
Chest Physiotherapy
Purpose
CPT is primarily used for patients with excessive bronchial secretions who have difficulty clearing...
