Rowing performance is strongly linked to the impulse generated during a counter-movement jump (CMJ). Monitoring CMJ force-time characteristics can help improve 2k rowing ergometer results and assess fatigue.
Area of Science:
- Sports Science
- Biomechanics
- Exercise Physiology
Background:
- Rowing is a demanding sport requiring both aerobic and anaerobic energy systems.
- The 2,000-meter (2k) race demands sustained high force output.
Purpose of the Study:
- To examine the connection between rowing ergometer (erg) performance and counter-movement jump (CMJ) force-time characteristics.
- To investigate if rowing-related low back pain (LBP) influences these relationships.
Main Methods:
- Rowers (n=27) completed a 2k ergometer time trial and a CMJ on force plates.
- Partial correlations analyzed the relationships between CMJ force-time data and 2k erg performance.
- The impact of LBP on these relationships was assessed.
Main Results:
- Positive Take-off Impulse showed the strongest correlation with 2k erg performance (r=0.71, p<0.001).
- Jump height was not significantly correlated with 2k erg performance (r=-0.13, p=0.518).
- Existing low back pain altered the relationship between Concentric Mean Force and 2k erg performance (r=0.74, p<0.001).
Conclusions:
- Positive Take-off Impulse is a key indicator for 2k ergometer performance in rowers.
- Longitudinal monitoring of CMJ impulse and force variables may track improvements and neuromuscular fatigue.
- These findings can inform individualized training programs to enhance rowing performance.

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...

Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
