Aim:
This study aimed to observe the effects of a concurrent physical training program (CPTP) on aerobic power and body composition in adults.
Methods:
The final sample was composed of 71 non-athletic men, randomized into 2 groups: experimental group (EG, N.=42, 45±8.46 years) and control group (CG, N.=29, 47±8.34 years). Body composition was assessed by Dual Energy X-ray Absorptiometry (DEXA) and aerobic power by maximal oxygen uptake (VO2max), obtained in the Cooper 12-minute run test. CPTP consisted of running training in the Fatmax intensity zone and strength training (squats and bench presses); three 40-minute sessions a week for 24 weeks. Descriptive and inferential analysis (intra-group: t-test and inter-group: 2x2 ANOVA and Sheffe post-hoc) was applied, and the Shapiro-Wilk test was used to test sample normality. The significance level was set at 5% for all tests.
Results:
A significant alteration was found in intra-group comparison for the EG, with respect to fat percentage (D=-1.13 kg; P<0.001), lean mass (D=0.29 kg; P=0.030) and VO2max (D=1.18 mL/kg/min; P<0.001).
Conclusion:
It can be inferred that CPTP caused an increase in aerobic power, evidenced in VO2max and enhanced body composition, with an increase in LM and reduction in F%.

01:20Exercise 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...

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...
01:26Exercise 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.
