Objective:
: The purpose of this study was to characterize the dynamic distribution of training loads in a kettlebell program and evaluate its effects on muscle strength and aerobic capacity.
Methods:
Fourteen recreationally active women with no kettlebell training experience (age: 25.86 ± 5.35 years; V̇O2max = 35.14 ± 5.58 mL/kg/min; body mass = 62.13 ± 13.40 kg; height = 164.75 ± 5.77 cm; body mass index = 22.68 ± 3.99 kg/m²) completed a 10-week kettlebell training program. The kettlebell training program was divided into three phases: Phase I (2 weeks), phase II (4 weeks), and Phase III (4 weeks). Maximum muscle strength (1RM) and aerobic fitness (V̇O2max) measurements were performed before (Pre) and after (Post) training. The external and internal loads were represented by the session's total volume and perceived exertion method.
Results:
An increase in maximum strength (P < .001; ∆% = 23.73; effect size = 0.87) and V̇O2max (P = .004; ∆% = 9.63; effect size = 0.57) was observed when comparing Pre and Post measurements. There was an increase in total volume when phases I and II (P < .001), phases I and III (P < .001), and phases II and III (P < .001) of the training were compared. The internal load values increased significantly between phases I and II (P < .001). However, there was no difference when comparing phases II and III (P = .796).
Conclusion:
The total volume increases during the training phases, and the training load was similar in phases II and III. Furthermore, were observed higher V̇O2max and strength (1 RM load) values.

01:24Respiratory Capacities
One key metric is the Inspiratory Capacity (IC), which represents the maximum amount of air that can be inhaled with full effort. IC is calculated by summing the tidal volume and inspiratory reserve volume, typically ranging from 2.4 to 3.6 liters.
The Functional Residual Capacity (FRC) represents the air in the...

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...

01:20Exercise 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...
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.
